An Empirical Study of User’s Self-Disclosure on RED Abstract: Emotional support on social media has become a significant predictor of online behaviors today. With a growing body of literature on online emotional support, it is necessary to explore its characteristics and effects in a Chinese setting. This study aims to generalize the features of emotional support on Chinese social media RED and examine the influence mechanism of RED users’ perceived emotional support on their self-disclosure via attachment. The results suggest that (1) people's perceived emotional support on RED is positively related to their extent of self-disclosure; (2) people's perceived emotional support on RED is positively related to the level of attachment security; (3) the level of attachment security is positively related to people's general extent of self-disclosure; (4) attachment security partially mediates the relationship between perceived emotional support and self-disclosure on RED.

Introduction 1.1 Overview Emotional support refers to a supportive message that contains feelings of trust, understanding, sympathy, or caring. Historically, the phrase has been used in psychology studies to better understand how people's emotional support affects others and their social well-being. In face-to-face communications, emotional support is delivered through both verbal and nonverbal expressions such as facial reactions, hugs, or eye contact. With the popularity of social media, online communications have gradually occupied a large part of human social life, which lead to an increasing academic interest in understanding emotional support in an online setting. A growing body of recent literature has combined emotional support to understand people’s social behaviors in online communities. In this case, emotional support not only consists of conditional supportive messages closely related to emotions but also contains online interactions such as liking, commenting, and reprinting. In recent years, a large number of preceding works in the disciplines of psychology and communication have examined the function of online emotional support. Unlike psychological research which directly refers to emotional support, communication scholars tend to measure the concept under the title of social support. Multiple studies have found that online social support, which includes instrumental, informational, and emotional support, is related to people's mental health and future use of online support groups, socio-commerce platforms, and social media (Yoo et al, 2014; Malecki & Demaray, 2003). People's perceived social support online, in particular, can increase their propensity to disclose personal information with other media users, with emotional support serving as an important predictor of their self-disclosure purpose, breadth, and depth (Weber et al., 2004). While Western scholars tend to notice the crucial role of emotional support in online interactions, Chinese researchers are more likely to focus on social support as a whole, suggesting the necessity to look closer into the specific emotional support in a Chinese setting. Regarding the emotional support literature to date, earlier studies have confirmed a positive and direct relationship between online emotional support and self-disclosure. However, few of them examined how these two variables might be impacted by additional variables, particularly adult attachment. Research on the relationship between emotional support, 1 attachment, and self-disclosure is also conducted independently (Hunter et al., 2006; Mikulincer & Nachshon, 1991), thus providing a new idea to investigate the indirect effect of emotional support on self-disclosure via attachment. Collectively, this study aims to examine the impact mechanism of emotional support on people's self-disclosing behavior through attachment security and to identify the features of emotionally supportive messages on Chinese social media by investigating RED users with an online questionnaire. As one of the most popular social media apps, RED has more than 170,780,000 monthly active users and experienced a fast growth of downloads in the past two years (iiMedia Ranking, 2022). The media is also famous for its amicable platform atmosphere which triggers a high frequency of emotional support exchange. Therefore, conducting the research on RED can not only target a diverse sample but can explore the role of emotional support on Chinses social media more precisely. Since previous works on RED mostly emphasized its characteristic as a socio-commerce platform, this study offers further insights into its social media functions. 1.2 Significances The particular significances of this study lie in its contributions to the existing emotional support and self-disclosure literature and a deepening of understandings about the role of online emotional support in people’s social life. First, it presents an overview of emotional support on RED and provides suggestions for future academics in the field. The present study indicates that RED users mostly exchange emotionally supportive messages on rational topics like knowledge popularization, showing the unique preferences of Chinese people to express sympathy or approval online. On the other hand, the findings of this study confirm that the positive effects of social media emotional support on secure attachment as well as self-disclosure can still apply to Chinese media, which further verifies the universality to predict people’s online activities by an irrational factor. Second, the findings of this study explain how emotional support can affect people’s online activities in a psychological process. Specifically, this study highlights the increasing importance of emotional factors in online interactions and its role in reducing people’s concerns about sharing personal details with unfamiliar others. It is noted that emotionally supportive messages not only encourage people to participate in media content creation but also satisfy 2 their multiple social needs by providing timely responses as well as a sense of safety within the socialization. 2. Literature Review 2.1 Emotional Support Offline and Online Emotional support is originally mentioned as a psychological concept within the context of social support, which mainly consists of two crucial parts: structural and functional support. Theoretically, structural support refers to the number of relationships within social interactions whereas functional support is more concerned with the quality of these relationships (e.g., emotional support) (Reblin & Uchino, 2008). Furthermore, functional social support can be divided into two types: received support and perceived support. In this case, emotional support refers to the perceived availability of caring, trusting individuals with whom life experiences can be shared (Brinker & Cheruvu, 2017). A large body of literature has investigated the definition of emotional support and its role in face-to-face communications. According to Burleson (1984), emotional support is an approach to help other people cope with depression by listening, empathizing, and rationalizing their feelings through conversations. Buhrmester et al. (1988) suggested that emotional support is a domain of people's interpersonal competence which can provide comfort when others are undergoing problems and distress. Being emotionally supported is also viewed as the determinant of intimacy development and people’s satisfaction with interpersonal relationships with friends, lovers, families, and colleagues at work (Cunningham & Barbee, 2012; Burleson, 2008). With the emerging use of the Internet and social media, online communications gradually extend face-to-face communications and thus change the landscape of how people exchange social support and emotional support with each other. Since the absence of nonverbal cues such as facial expressions and touch (Wright, 2012), online social support that may help social media users has greatly relied on messages and is naturally intangible. Previous research states that social support from the internet generally covers at least three aspects: instrumental, informational, and emotional support (X. Li et al., 2015). Specifically, instrumental support is the provision of tangible help including financial and material assistance as well as needed 3 services. Informational support encompasses the given messages from online communities that could help people cope with their problems in the form of advice, knowledge, or referrals. Emotional support refers to providing messages that involve emotional concerns like trust, caring, understanding, encouragement, affirmations, or sympathy (Malecki & Demaray, 2003; Taylor et al., 2004). Different from instrumental and informational support that offer helps to other users directly, emotional support in the virtual environment is expected to be beneficial in an indirect way (Liang et al., 2011). Within a social media context, likes, favorites, and upvotes are all examples of ways in which emotional support is provided (Liu & Ma, 2020). In the current study, online emotional support is defined as a form of emotionally supportive message that encompasses an individual’s perceived feelings of trust, understanding, caring, sympathy, or encouragement, and also includes social interactive behaviors such as likes, favorites, and collections. Considerable research attention has been devoted to the effect of emotional support on individuals’ psychological health and social well-being within online communities. Wang and colleagues (2012) claimed that emotional support people obtained in online support groups can strengthen their perceived bond with support providers and is strongly associated with their increased group commitment. In a study of members’ mental health outcomes in an online breast cancer support community, Yoo and the team (2014) found that breast cancer patients who participate in exchanging emotional support show better performance in their emotional well-being. Emotional support is also found to be helpful with teacher-student interactions through the internet. An analysis of online collaborative learning demonstrated that emotional support can establish strong socio-emotional bonds within a work team and can create a climate of trust as well as a sense of belonging among team members (Hernández-Sellés et al., 2019). In an e-commerce setting, emotional support is proven to be strongly associated with customers' behaviors. Liang et al. (2011) yielded that emotional support from other users is positively related to people's perceived relationship quality on social commerce platforms and thus has a significant effect on their continuous use of online shopping sites. Scholars have also noted that emotional support on social commerce sites can generate familiarity among customers which promotes their relationship intimacy (Li, 2017). According to Hammouri and Abu-Shanab (2017), emotional social support provided by other consumers on online 4 communities can establish a long-term trust toward specific brands and promote purchase behavior in online market. Despite a massive number of studies centered on various online forums, numerous studies have also attempted to explain the provision of emotional support in a more general type of online communities such as Social Networking Sites (SNSs) and social media (e.g., Facebook and Microblog). Past work indicated that emotional support from online friends can promote people's satisfaction with their online social life, and thus lead to better online well-being and affect their continuous use and commitment to SNSs (Lee et al., 2013; Lin et al., 2016). In an analysis of the impact of Facebook emotional support on college students' perceived stress, Wright (2012) reported that online emotional support can greatly reduce an individual's perceived life stress and is strongly associated with the homophily they perceived with others. However, some scholars have argued that online emotional support may also generate negative feelings at the same time (Shensa et al., 2020). For example, McCloskey et al. (2015) reported in a newly developed measure of Facebook social support that emotional support from social media is associated with higher depression and loneliness. Shensa et al. (2020) similarly claimed that Facebook emotional support is associated with greater depression risks among young adults. Furthermore, being emotionally supported online can also contribute to people's internet addiction and media dropout (Liu & Ma, 2020; Chang et al., 2019). Collectively, prior studies have outlined the critical role of online emotional support in people's social interactions and media use behaviors. Receiving emotional support from the internet is not only associated with human emotional needs (e.g., fighting against passive feelings) but is significantly related to people's social demands (e.g., building up relationships). Since past works have devoted less attention to examining the impact of emotional support on media users' behavior than other influence factors, it is necessary to explore how online emotional support can change people's media use especially in a Chinese context. 2.2 Online Self-disclosure and Emotional Support Self-disclosure has been mentioned by Jourard and Lasakow (1958) as an approach to an individual making the self known to others and was redefined as a process of telling one’s self-related information, honestly sharing one’s personal, private thoughts and feelings with another person (Jourard, 1971). Traditionally, scholars have used the term as a personality 5 construct in research or to describe the process within social interactions simultaneously (Cozby, 1973). In face-to-face communications, self-disclosure not only promotes interpersonal relationships but also acts as a crucial part of developing intimacy and trust between couples. Researchers have also highlighted that self-disclosure is a reciprocal process where one person's disclosure can encourage other people to disclose the self responsively (Greene et al., 2006). To this end, the reciprocity of disclosure appears to be a norm of social interactions today, especially with the growing popularity of social media. With the integration of social media, people today can connect and interact with each other across geographic and time limits. Compared to the counterpart in face-to-face communication, self-disclosure on social media is granted with new patterns due to the strong connectivity as well as anonymous environment of internet. Typically, online self-disclosure is aimed at multiple people where as self-disclosure of offline communication occurs in a relatively smaller group. By liking, commenting, and sharing multiple media content, individuals disclose their identity, social networks, and social interactions purposefully and publicly. Self-disclosure, therefore, becomes the core behavior on social media and is recognized as a promotor of people’s communication frequency in online contexts (Caplan, 2007). Considerable research attention has been devoted to understanding the determinants of self-disclosure. For example, Rime et al. (1998) reported in a study about the social sharing of emotions that people tend to disclose themselves when experiencing emotionally intense events. Collins and Miller (1994) have noted that liking can motivate people to self-disclose during interactions. Partners’ responsive disclosure can also be a strong predictor of people’s disclosive behaviors (Reis & Shaver, 1988). Collectively, an individual's disclosive behaviors are greatly affected by various motives including internal, social, and contextual factors. Internal factor, in this case, is related to one person's psychological state which may reflect on their psychological needs and thus influence the disclosure productions online (Luo & Hancock, 2020). Study of disclosure reported that those with psychological distress may show a greater desire to express themselves through the internet to cope with stress and work off steam (Pennebaker, 1997). It is also proved that people who perceive higher levels of stress can trigger greater amounts of self-disclosure on social media than those with less pressure. Unlike the one motivated by internal reasons, self-disclosure driven by social factors such 6 as relational development aims to develop relational connection and intimacy with others. As stated by Lai and Yang (2015), interpersonal needs of relational maintenance have a significant effect on individuals’ self-disclosure behavior. More specifically, people who are in need of interacting or contacting with online friends show higher propensity to disclose the self at a great extent on social media. According to Luo and Hancock (2020), people who are lonely and socially anxious in real life self-disclose more through online networking to compensate for a lack of interpersonal interactions. Previous researches have also shown that self-disclosure on social media is strongly associated with interpersonal closeness in which social media users can express affinity to make up for the textual environment in an online setting (Hollenbaugh & Ferris, 2014). Drawing on an extensive range of sources, Desjarlais et al. (2015) yielded in a literature review that the context factor, which refers to the online environment, also contributes to people's self-disclosure online. The absence of identity cues and anonymity on social media make it easier for users to disclose any kind of content across the board compared to real-name setting offline. People’s perceptions of network responsiveness, on the other hand, also contribute to their disclosive behaviors with which people may disclose themselves more openly if they think their social media network is more responsive (Walsh et al., 2020). Prior studies also found a positive effect between trust and self-disclosure in which trust can predict an individual's self-disclosure online (Taddei & Contena, 2013). In an analysis of customer self-disclosure on sci-commerce sites, Bansal et al. (2010) indicated that customers show greater proneness to reveal information if they have a higher level of trust in brands and websites via perceived customer care. The finding, which highlighted the role of customer care, may suggest that people's self-disclosure can be affected by emotional elements. To date, a number of studies have examined the impact of emotional support on people’s disclosive behaviors. Y. Lin and Chu (2021) investigated the association between online self-disclosure and intimacy development on social media and found that users who have a sense of emotional support from the sites tend to engage in self-disclosure with considerable depth and breadth. Weber et al. (2004) similarly demonstrated that emotional support has a positive effect on people’s intent to self-disclose online. It is also proved that a favorable social support environment as well as positive emotional support can significantly encourage people 7 to share information and reveal personal stories online (Zhou, 2017). Despite the growing body of research drawing attention to how emotional support can predict people’s disclosure, most studies, however, centered on emotional support as the benefit and result of self-disclosing online (Lu & Hampton, 2017; Wang et al., 2015). In this case, to further explore the impact of emotional support on an individual's self-disclosure can not only fill in the gaps of relevant research but establish a better understanding of how emotional elements can facilitate people’s media use. Therefore, the following hypothesis is proposed: H1: The user's perceived emotional support is positively related to his/her self-disclosure on RED. 2.3 The Role of Attachment in Online Behaviors The term “attachment” is a psychological construct which initially developed by Bowlby (1969) in the study of parent-child relationships. Accordingly, Bowlby (1969) concluded that attachment is a unique emotional bond between infants and mothers or caregivers and highlighted that infants will react strongly when being departed from their mothers. The finding then established a foundation for attachment research today. In an analysis of how childhood attachment styles help form adult attachment styles, Ainsworth et al. (1978) concluded that people can be divided into secure individuals, anxious-ambivalent individuals, and anxious-avoidant individuals based on different levels of attachment anxiety and avoidance. To this end, attachment has multiple characteristics of which to seek support and comfort from attached partners when being frightened or afraid and becoming anxious when being separated from the partners (Cao et al., 2016). Based on the attachment framework above, considerable scholars have applied the theory to adult relationships. For example, Hazan and Shaver (1987) yielded in the study of couples and found that attachment styles formed by parent-child attachments are significantly associated with the caretaking behaviors between romantic partners. The exploration of adult attachment was then extended to the domain of friendship, in which Fraley and Davis (1997) reported that secure friendships are not only beneficial to a secure romantic attachment but can also provide single individuals with primary attachment. Along with the increasing number of attachment researches, recent studies have shifted attention from interpersonal attachment to place attachment, brand attachment, and so forth. For example, Hidalgo et al. (2001) developed 8 the term “place attachment” to explain a positive emotional tie between individuals and specific spots, emphasizing the effect of emotional elements within attachment as well as an individual's action intent on strong emotional attachments. In the marketing domain, prior study reported that consumers with a higher level of attachment toward the brand or products are more willing to maintain a long-term relationship with the firm and purchase their products repeatedly (Liu, 2020). With regard to information system domains, prior researchers have noted the applicability of using attachment theory to explain people’s online behaviors. Similar to place attachment, people can form attachment relationships with virtual communities through their interactions online (Goel et al., 2011), which further leads to their continuous use of the medium. Choi (2013) claimed in an empirical study that online user attachments have a positive effect on people’s intention to participate in online communications. In the context of social media, people's attachment styles are significantly associated with people's engagement with the media. Theoretically, one person's attachment styles can reflect his or her unique cognitions, emotions, and behaviors in close relationships. Ren et al. (2012) yielded that different types of attachment styles can result in variance between people's informational behaviors. According to Shaver and Mikulincer (2007), individual attachment styles predict the way how people interact with acquaintances and strangers. An empirical study of young people's interactive behaviors in virtual social networks reported that secure individuals are more likely to develop more social ties and initiate web-based relationships (Yaakobi & Goldenberg, 2014). They also revealed that a decreased avoidance score can result in an increased willingness to information dissemination online. Despite a large body of studies about individual variance in attachment styles to important others, some scholar devoted their attention to intrapersonal variability of attachments across relational partners (La Guardia et al., 2000). In line with Self-Determination Theory, La Guardia and colleagues (2000) established the A-R-C model to explain the mechanism of how people form secure attachment in communications and noted that attachment security is significantly linked with psychological need fulfillment. To this end, the degree of an individual's secure attachment is well predicted by how much they are satisfied with the needs of autonomy, relatedness, and competence (La Guardia et al., 2000). Accordingly, autonomy 9 need refers to one person's recognition and choice of behavior when he or she perceives the external environment as satisfied. Relatedness need relates to an individual's desire to pursue a sense of belonging in a group and to form strong relationships with others. Competence need is people's perceived feeling of capability and increased effectiveness when accomplishing certain tasks. Past work has applied the A-R-C model and proved that users' emotional attachment, determined by three primary demands, can effectively explain and predict their stickiness toward social networks through online interactions (X. Ren, 2018). 2.4 Relations between Emotional Support, Attachment, and Self-disclosure A growing body of research today has indicated that there is a correlation between emotional support, attachment as well as self-disclosure. With regard to the workplace domain, prior researchers have investigated the mechanism of how workers' perceived emotional support can generate a sense of attachment in organizations. For example, Nelson and Quick (1991) noted that newcomers who need help will form attachments with others who provide them with protection and nurturance. In the context of social media, people can seek emotional benefits through online interactions with other people (X. Ren, 2018). Past work has found that members from virtual communities can receive emotional support from each other with a high frequency of commenting or liking (Tu & Chen, 2015). In a qualitative study of online supportive content, K. Huang et al. (2010) examined the characteristics of informational and emotional support provided in support communities and suggested that emotional support from other members may generate emotional comfort and attachment. In the same vein, Hunter et al. (2006) found that emotional support from caregivers is positively correlated with the degree to which recipients are securely attached. Yet, multiple studies have reported a positive relationship between emotional support and individual attachment; however, few draw their attention to investigating whether people's perceived emotional support from social media makes a difference to their level of attachment security. To this end, the current study plans to further verify the influence relationship between these two factors and examine how much can emotional support promote people’s overall attachment security. Hence, the following hypothesis is proposed: H2: The user's perceived emotional support is positively related to the level of his/her attachment security. 10 Referring to individual attachment and self-disclosure online, scholars to date have considered the role of attachment in predicting the way in which people disclose themselves in an internet setting. Shang and colleagues reported in 2015 that people’s attachment style can change their posting and interactive behaviors on social network. According to C. Huant et al. (2019), attachment security is effective in measuring individuals' numbers of social ties as well as the intention to develop web-based relationships with others through online communications. Prior works have also indicated that secure people not only show more self-disclosure but also feel more comfortable interacting with other people online (Mikulincer & Nachshon, 1991; Keelan et al., 1998; Wei et al., 2005). Grabill and Kerns (2000) similarly reported a positive effect of secure attachment to self-disclosure in a short-term adult relationship. According to Welch and Houser (2010), a securely attached individual is demonstrated to be more satisfied with relationships and disclose more about the self to their interactive partner. In contrast to previous studies, Aharony (2016) argued that there is a negative correlation between attachment security and people’s self-disclosure online and highlighted that insecurely attached people disclose themselves more on Facebook due to their avoidance of face-to-face communications. Similarly, Keelan and colleagues (1998) reported in a study of individuals’ online relationship satisfaction that people with an insecure attachment style disclose more intimate information to strangers through social networking sites. In view of all that has been mentioned so far, one may suppose that the level of attachment security is a strong predictor of people's self-disclosing behaviors within the online environment. Since there are conversed findings about how people's degree of security can result in less or more self-disclosure, it is necessary to re-examine the association between these two elements. Hence, the following hypothesis is proposed: H3: The level of the user's attachment security is positively related to his/her self-disclosure. Along with past works that involve attachment in investigations about emotional support as well as self-disclosure, several studies have identified a mediating effect of attachment in people's emotional experiences and their future behaviors. For example, Cai et al. (2013) reported a mediating effect of attachment within the relationship between authoritative parenting to Chinese adolescent-parent communications, indicating that a lack of emotional 11 support from parents predicts adolescents' less frequency to disclose themselves with parents via a lower degree of secure attachment. Collectively, previous investigations on the role of attachment in relation to emotional support and self-disclosure are mutually independent, and less is known about whether attachment can affect the influence path from an individual's perceived emotional support and the act of self-disclosing. To this end, the following research question is proposed: RQ1: Does the level of users' attachment security mediate the relationship between their perceived emotional support and online self-disclosure? In light of the fact that people are likely to spend more time on social media, it becomes important to discuss how the frequency of participating in online interactions may impact a person's online behavior. In the e-commerce domain, scholars have indicated that the more consumers participate in social interactions through social media, the more likely they are to purchase certain products online in the future (Kozinets et al., 2010). Further, the number of individuals’ interpersonal communication within online communities is also closely related to their emotional bonding as well as an attachment to other members, which therefore motivates them to join online value co-creation (Shen et al., 2020). With regard to communication studies, a considerable body of work has indicated that the time people spent on online interactions negatively correlates with their perception of emotional support (Shensa et al., 2016) and is positively associated with increasing media addiction (Liu & Ma, 2020). Yet, little evidence is found to support the correlations between the frequency of online interactions, perceived emotional support, and self-disclosure. Therefore, it is of great significance to discuss and further explore how people’s frequency to interact with other social media users can change their perceptions of online emotional support, the overall level of attachment security, and the extent to which they self-disclose information on social emdia. Thus, the following research question is proposed: RQ2: What are the effects of online interaction frequency on RED users’ perceived emotional support, attachment security, and self-disclosure? Gender is found to be an important factor in people’s perception of emotional support and self-disclosure online (Nelson & Quick, 1991; Cosby, 1973). Prior studies indicated that gender not only affects people’s attitude to emotional support but also influences their choices of what 12 and how much to disclose in online interactions (Burleson, 2003; Bond, 2009). Traditionally, females are thought to be more considerate and have a greater desire to tell personal stories. Males are generally thought to be tougher and stronger, as they tend to withhold personal feelings when communicating with others. In an online environment, women are more sensitive to emotional support and more likely to disclose multiple topics than men. However, men show a greater desire to start intimate communication with new friends online than women do (Bond, 2009). Despite multiple studies that found significant differences between women and men in perceived support and self-disclosure, some scholars argued that there are no obvious distinctions between genders in online communications, especially for those who come from the same cultural background (Burleson, 2003). Thus, there is a need to explore gender variances in perceived emotional support and self-disclosure on Chinese social media RED. In this study, gender differences are explored through the following research question: RQ3: What are the differences in perceived emotional support, attachment security, and self-disclosure as reported by males versus females? Taken together, the present study aims to generalize the characteristics of emotional support on RED and investigate the mechanism by which RED user’s perceived emotional support affects their online self-disclosure. Additionally, the study also intends to examine the mediation effect of attachment security within the relationship of emotional support and self-disclosure. Based on the above hypothesizes and research questions, a conceptual model of this study is proposed (see Figure 2.4.1).

Methodology 3.1 Methods A quantitative method was conducted to provide a generalizable knowledge base to explain the impact mechanism of perceived emotional support on individuals' online self-disclosure. To ensure participant diversity and time efficiency, the study used an online questionnaire to collect information. Figure 3.1.1 presents an overview of research process. Figure 3.1.1 Research process 3.2 Participants Respondents were recruited from online communities of Jinan University and RED by random sampling. Since this study centered on the impact of perceived emotional support from RED on its user’s self-disclosure, participants selected for the survey were RED users who perceived the media as a social platform for daily use. A total of 402 individuals completed the survey but 84 cases were excluded due to the low quality of answers (see Table 4.1.1). The final data set included 318 RED users, consisting of 179 females (56.3%) and 139 males (43.7%). All of them were from mainland China. The majority of participants were aged between 18 and 25 years (N = 222, 69.8%), followed by people from the 26-30 years group (N = 68, 21.4%) and those who were over 30 years (N = 25, 7.9%). Only 3 people were under 18 years old (0.9%). All of the participants have joined in 14 social interactions with other people on RED before, including liking (N = 302, 95%), favoriting (N = 300, 94.3%), commenting (N = 283, 89%), and notes creations (N = 259, 81%). 3.3 Measurements The survey questionnaire used a variety of established measures. Overall, it included 9 non-scale items for general information and 33 scale items for specific measured dimensions: Emotional Support (ES), Attachment Security (AS), and Self-Disclosure (SD). Participants were asked to complete the questionnaire referring to their interactive experience on RED. In the current study, Cronbach's alpha of 42 items in total was 0.953. Descriptions and reliabilities for each scale are reported below. Emotional Support. The current study assessed perceived emotional support from RED using the Communication-Based Emotional Support Scale (CBESS) developed by Weber and Patterson (1996) to specifically measure people’s perceptions of communication-based emotional support adequacy (see 3.4.1). The CBESS was originally used to measure emotional support within romantic relationships and has been successfully conducted to measure individuals' perceived emotional support in different contexts, including online support groups and other online communities. Wright (2012) applied the CBESS to measure undergraduate students' perceived emotional support on Facebook and examine how their perceived emotional support online can impact their trust in others and self-disclosure behaviors. In a study of relationships between individual Facebook use and emotional support, Rethwish (2018) conducted the CBESS to observe people’s perceived emotional support from acebook networks. Specifically, CBESS consists of 1 items including statements like “He/she is a good listener when I am upset” and “He/she shows genuine concern for my problems” after the re-examination for better validation and reached a Cronbach’s alpha of 0.9 in general (Weber & Patterson, 1996). The current study translated the original English version of CBESS into Chinese and changed all converse statements into positive items for a more convenient data analysis. Collectively, the measurement of RED users' perceived emotional support contained 13 items in total through a 5-point Likert scale. Participants were required to rate each statement to the degree from which they "strongly disagree” (1) to “strongly agree” (5). 15 Table 3.4.1 Items of emotional support measurement onstruct Emotional Support tems eference ES01 There are people on RED who help me work through my thoughts and feelings about ma or life decisions (e.g., career choice). Weber and Patterson (1996) ES02 There are people on RED who patiently and sensitively listen to me let off steam about an outside problem that I am having. ES0 When I tell other RED users about a problem that I am having, they seem to be paying attention to me. ES0 There are people on RED who help me cope with problems concerning my friends and/or family members. ES05 There are people on RED who come to me when I am depressed. ES06 There are people on RED who are a good listener when I am upset. ES07 There are people on RED who say and do supportive things for me when I am feeling down. ES08 When I want to talk to other RED users about what is bothering me, they seem to be with full concentration. ES09 There are people on RED who show genuine concern for my problems. ES10 There are people on RED who gives me good advice when I ask for it. ES11 There are people on RED who makes it very easy to discuss my personal feelings. ES12 There are people on RED who listen to my side of the story even if they think that I am wrong. ES1 There are people on RED who make an effort to make me feel better when I am depressed. Self-Disclosure. The current study adopted a modified version of Self-Disclosure Scales which was originally developed by Wheeless and Gotz in 1976 (see 3.4.2). Originally, Wheeless and Gotz’s scale (1976) refers to an individual's self-reported disclosure within interpersonal relationships and is measured by 21 items ranging from five different dimensions: the amount of self-disclosure, consciously intended disclosure, honesty-accuracy of disclosure, positiveness-negativeness of disclosure, and depth-intimacy of disclosure. Although the scale is beneficial in measuring people’s self-disclosure model within multiple settings, it fails to involve new patterns of online interactions in an anonymous environment. With the popularity of social media, individuals tend to establish weak-tie relationships with others and avoid disclosing personal details deeply and openly. To this end, Park and colleagues (2011) excluded the dimension of depth-intimacy of disclosure and revised the primary statements into a 17-item scale to measure online users' self-disclosure on Facebook, covering dimensions of self-disclosure amount, honesty, intent, and positivity. The Cronbach’s alpha of Park’s instrument was ranged from 0.68 to 0.79. To ensure the validity of data collection, some items from Park's self-disclosure scale were combined and deleted after translation from English to Chinese and the pilot test in this study. The Chinese version of the self-disclosure scale referenced Cao's revised general self-disclosure scale in investigating Chinese students' 16 disclosing behaviors on Microblog (Y. Cao, 2014). Overall, this study's survey retained two to three items under each dimension and developed an 11-item scale to measure RED users' self-disclosure. Participants were required to complete the questionnaire by scoring from "strongly disagree" (1) to "strongly agree" (5). Reverse statements were modified to positive descriptions. Table 3.4.2 Items of self-disclosure measurement onstruct Self Disclosure tems eferences SD01 I frequently talk about myself on RED. SD02 I usually write about myself extensively on RED.

SD07 When I reveal my feelings about myself on RED, I consciously intend to do so. SD08 When I wish, my self disclosures in RED are always accurate reflections of who I really am. SD09 I usually disclose positive things about myself on RED. SD10 n the whole, my disclosures about myself on RED are more positive than negative. SD11 I don t often disclose negative things about myself on RED. Attachment Security. The current study applied the 9-item Need Satisfaction Scale developed by La Guardia and the team (2000) to measure the degree of people's attachment security on RED (see 3.4.3). In line with Self Determination Theory, the need satisfaction scale involved within-person factors to predict how much people are securely attached to relational others and is centered on three primary demands of individuals in interpersonal communications, including needs for autonomy, relatedness, and competence (La Guardia et al., 2000). It is noted that the more one person's three basic demands are satisfied, the higher level of attachment security he or she develops. Generally, the Cronbach’s alpha of La Guardia’s instrument was ranged from 0.91 to 0.97. Referring to empirical study domains, X. Ren (2018) has adopted the need satisfaction scale to access social media users' emotional attachment to online interactions. Xiao (2022) also applied the scale to measure sports fitness APP users' emotional attachment to the medium and further examine how people's attachment predicts their intention of continuous use. In the current study, participants were presented with a Chinese version of the 9-item need satisfaction scale along with a modification of reversed descriptions. Participants were required to score each statement from "strongly disagree" (1) to 17 "strongly agree" (5).

This platform can generate exclusive link and QR code for each survey, facilitating the current study to forward and spread the questionnaire through multiple platforms including WeChat and RED. Based on personal social networks and online chatgroups, this study distributed the survey with a snowball sampling approach and obtained massive first-hand data conveniently. Before the formal questionnaire was issued, a preliminary survey was conducted on the target population. 56 valid responses were gathered and no items were changed or deleted. Formal data were collected from March 10 to March 15 in 2023. Participants in this study were asked to complete all survey items after providing informed consent. If there was a missing answer, participants would not be able to submit the answers. Past experience using RED was measured first, followed by a battery of questions referring to participants' perceptions of emotionally supportive messages on RED. In the first four questions, participants were asked to report the frequency of how often they like, comment, collect others' notes and create their own media content on RED. The following questions examined the specific topics (“which of the following topics provide you with emotionally supportive messages the most”) and strategies (“which of the following expressions describe the emotionally supportive messages you encounter or receive the best”) that participants received emotionally supportive messages from, which specifically related to their experience on RED. These two questions served to establish a general picture of individuals' perceived 18 emotional support online. Next, participants completed a multidimensional scale by rating the degree to which statements best described their feelings and behaviors in online interactions. 13 items like “There are people on RED who are a good listener when I am upset” were applied to measure people’s perceived emotional support. Another 9 items formed a composite approach for people’s attachment security, including “When I am using RED, I feel loved and cared about”. Self-disclosure was measured by 11 items including “I frequently talk about myself on RED”. After completing the current scale, participants were debriefed and thanked for their participation. As part of the follow-up phase of the investigation, ethical considerations and answer validity problems were discussed. Firstly, respondents' data were only used for academic purposes and destroyed when the study was completed to ensure anonymity and confidentiality. Secondly, all of the responses were screened according to two basic criteria: (1) the response time should not be less than 60 seconds, and (2) all of the options for the survey questions must not be identical. 3.5 Data Analysis The first stage of the current study centers on measuring the reliability and validity of the current questionnaire. Subsequently, descriptive statistics and correlation statistics are applied to make further insight into different genders' patterns of using RED and to establish a general picture of emotional support sources. Since the current study used a self-reported online survey as a single instrument to collect data, Harman’s one-factor test is employed in the following stage to check the possibility of common method bias and eliminate systematic errors caused by artificial and latent elements. Next, the current study applied structural equation modeling (SEM) to test the hypotheses and establish a theoretical model based on three variables including emotional support, attachment security, and self-disclosure. As a powerful technique in scientific investigations, SEM is increasingly used to examine and evaluate multivariate casual relationships through path analysis, providing a convenient method to verify direct and indirect effects between variables in the present study. Finally, mediation analysis is conducted to answer the research question through a bootstrap methodology that examines the mediate effect of attachment security by repeated sampling and 95% confidence intervals. 19 4. Results of Data Analysis 4.1 Descriptive Statistics A gross sample of 402 RED users was collected from the online survey and none of them participated in the pretest. After excluding unusable data based on time and quality criteria, the final sample of the current investigation contained 318 respondents, including 179 female participants (56.3%) and 139 male participants (43.7%). The average age of the participants was 26.05 years (SD = 11.60). The composition of the sample's educational background was 79.6% with a bachelor's degree, 11.3% with a college degree or less, and 9.1% with a master's degree. None of the respondents had a doctorate degree. As far as interaction frequency (including the act to like, favorite, comment, and content creation) is concerned, 8.5% never or rarely liked, favorited, commented, or created media content on RED, 41.8% sometimes engaged in these activities, 40% reported a higher frequency to do so, and 9.7% reported interacting with others on RED most often. Table 4.1.1 shows the respondents' characteristics regarding demographic details and online interactions. With regard to sources of the emotionally supportive message, media content related to knowledge sharing as well as popular science (M = 2.78) was ranked as the most frequently seen topic that provide participants with emotional support, followed by topics related to daily life sharing and product recommendation (M = 2.69), emotion and relationships consulting (M = 2.27), and hobbies (M = 2.26). Table 4.1.2 shows the ranking of each topic by their average score. Nevertheless, participants also rated on emotional support strategy according to how often did they receive emotional support through six types of expressions (see Table 4.1.3). These various expressions represented six different emotional supportive strategies from S. Liu et al.'s (2021) Emotional Support Conversation Framework. In this case, reflecting on others' feelings (M = 4.05), responding with self-disclosure (M = 4.00), and providing affirmation and assurance (M = 3.60) were the top 3 most frequently used strategies to convey emotional support on RED. Table 4.1.3 presents the ranking of each strategy by its average score. 20 Table 4.1.1 Descriptive statistics of the participant demographic information ate ory tems um er ender ale 1 9 emale 179 .7 56. e 18 0.9 18 25 222 69.8 26 0 68 21. 0 25 7.9 6 11.

Cronbach's alpha of the 33-item measurement is 0.953 (emotional support = 0.939, attachment security = 0.913, self-disclosure = 0.934), showing good consistency and stability of this instrument (see Table 4.2.1). Table 4.2.1 Construct reliability Confirmatory factor analysis (CFA) was applied to test measurement accuracy by convergent validity as well as discriminant validity. Convergent validity was measured by average variance extracted (AVE) and composite reliability (CR) (see Table 4.2.2). In general, AVE values of each construct are greater than a recommended level of 0.5 and all CR values are higher than a marginal value of 0.7, indicating that the current instrument has satisfactory reliability and convergence validity. In addition, all factor loadings from CFA results are significant in the t-test and well above 0.60, providing strong evidence of good convergent validity. Discriminant validity was examined through the inter-construct correlations by comparing the square root of AVE for each dimension with a correlation of latent elements. Table 4.2.3 illustrates that all AVEs are higher than the maximum correlation coefficient between factors, which is supported for discriminant validity. 4.3 Common Method Variance Since the data was collected from a single survey measurement, there was potential for common method bias in the present study. Common method bias can exist when independent and dependent variables are measured by one survey and through the same response method. To this end, Harman’s single factor test was applied to eliminate this systematic error. The results indicate that the first factor with an eigenvalue greater than 1 explains 40.2% of the covariance in the current study, and is lower than the threshold of 50% (Hair et al., 1988), providing evidence of the absence of a common method bias. 22 Table 4.2.2 Results of confirmatory factor analysis onstructs ndicators Emotional support ttachment Security Self Disclosure ote s CR oadin s ES01 0.71 ES02 0.8 2 ES0 0.72 ES0 0.716 ES05 0.7 5 ES06 0.759 ES07 0.71 ES08 0.7 6 ES09 0.697 ES10 0.681 ES11 0.7 7 ES12 0.77 ES1 0.751 S01 0.69 S02 0.818 S0 0.695 S0 0.72 S05 0.785 S06 0.768 S07 0.72 S08 0.679 S09 0.721 SD01 0.788 SD02 0.8 6 SD0 0.7 SD0 0.727 SD05 0.725 SD06 0.799 SD07 0.687 SD08 0.8 5 SD09 0.705 SD10 0.719 SD11 0.7 Composite Reliability E A E 0.9 0.5 8 0.91 0.5 0.9 7 0.579 verage ariance Extracted. 23 p 0.001 Table 4.2.3 Inter-construct correlations 4.4 Structural Model After the preliminary steps of data analysis (measurement model and common method variance) were carried out, structural equation modeling (SEM) was employed to test the proposed hypothesized relationships through AMOS 25.0. As one of the most popular methods in quantitative investigations, SEM is capable of providing a precise evaluation of measurement errors, assessing latent variables through observed variables, and conducting a model test on the proposed structure in which data fit can be evaluated (Kaplan, 2008). Results of structural equation modeling including model fit as well as path estimates are shown in Figure 4.4.1. In general, the structural model obtains acceptable model fit (X2 = 649.173, df = 492, p < 0.001, X2/df = 1.320, RMSEA = 0.032, CFI = 0.975, NFI = 0.906, TLI = 0.974, IFI = 0.976), indicating that it can be processed through path analysis. As shown in Figure 4.4.1, RED users' perceived emotional support online accounts for 33% of the variance in their level of attachment security (R2 = 0.33) and explains 37% of the variance together with the level of secure attachment in the extent of self-disclosure (R2 = 0.37). Both of the model fits (R2) are greater than 0.33 which indicates that the proposed structural model achieves an acceptable level of explanatory power.

As illustrated in the table, standardized coefficients of path estimates indicate a positive and significant relationship between perceived emotional support and self-disclosure (β= 0.263, t = 4.079, p < 0.001), which provides strong evidence for Hypothesis 1. Perceived emotional support is also found to be positively related to the level of attachment security (β= 0.574, t = 8.282, p < 0.001), thus supporting the proposed Hypothesis 2. In addition, the relationship between the level of attachment security and self-disclosure is established (β= 0.420, t = 6.044, p < 0.001), confirming the proposed Hypothesis 3. Collectively, these findings demonstrated that people's perceived emotional support on RED can not only lead to their greater desire to self-disclose but also a higher level of attachment security while interacting with each other.

In the present study, perceived emotional support is modeled as the independent variable of people's self-disclosure online. Based on the theoretical review, the level of attachment security is involved as a proposed mediator within the relationship between perceived emotional support and self-disclosure. This study referred to Baron and enny’s (1986) guidelines as well as Preacher and Hayes’s (2008) bootstrap approach to test the mediating effect of attachment security and further examine its significance. Regression analysis was conducted first to test whether the mediating effect is complete or partial. According to Baron and Kenny (1986), three conditions should be met in the results to support mediation: (1) the independent variable significantly impacts the dependent variable in the first regression analysis; (2) the independent variable significantly impacts the mediator in 25 the second regression analysis; (3) the mediator significantly impacts the dependent variable in the third regression analysis, in which both independent variable and mediator are entered as predictors. In this case, completed mediation is supported if all conditions are met and the independent variable no longer affects the dependent variable when the mediator is controlled. Partial mediation presents if the independent variable’s influence on the dependent variable is reduced after the mediator is controlled (Baron and Kenny, 1986). Table 4.5.1 presents the results of the mediation analysis to support each condition. As shown, the direct effect without the mediator established a significant correlation between emotional support and self-disclosure (β= 0.520, p < 0.001). When the mediator is involved, the direct effect of emotional support on self-disclosure (β= 0.292, p < 0.001) sees a decrease, thus providing evidence of partial mediation.

Bootstrapping method was employed to assess the significance of mediating effect in the next stage. In line with Preacher and Hayes’s (2008), the current study applied 5,000 bootstrap iterations and 95% confidence intervals as the measurement. If the confidence interval excludes zero, the indirect effect is significant. Moreover, if the direct effect of the mediator is significant at the same time, the mediation is not completed. As shown in Table 4.5.1, attachment security significantly and partially mediates the path from emotional support to self-disclosure (β= 0.228, p < 0.001, CI = 0.158 to 0.319). 4.6 Impact of Interaction Frequency and Gender Differences A Pearson correlation coefficient was computed to assess the linear relationship between people’s online interaction frequency, their perception of emotional support, attachment security, and self-disclosure. As presented in Table 4.6.1, the frequency of people participating in online interactions on RED (like, favorite, comment, and content creation) presents a small positive correlation with both perceived emotional support (r = 0.194, p < 0.001) and self-disclosure (r = 0.190, p < 0.001). However, no significant relationship is found between the 26 frequency of interaction and attachment security (r = 0.043, p > 0.1).

One difference was found in terms of emotional support, as males reported emotional support from other RED users as more adequate than did females (t = 5.517, p < 0.001). With respect to attachment security, men reported a higher level of attachment security compared to women (t = 5.545, p < 0.001). Referring to self-disclosure, the extent to which men self-disclose on RED is greater than that of females (t = 6.600, p < 0.001). 5. Findings and Discussions The constantly updating social media has brought about new changes in people's online behaviors and triggered increasing academic attention to exploring the motives that may contribute to the change. In this case, emotional support as a psychological term is introduced to communication studies and shows substantial power to predict individuals' online behaviors. Despite a growing body of literature studying the causes and possible impact of emotional support, less is known about how emotional support from social media can affect people's self-disclosure behaviors online. Therefore, the current study centers on the role of emotional support on Chinese social media RED in fostering people to participate in online interactions 27 and self-disclosure. In general, this study aims to generalize the characteristics of emotional support on RED and examine the impact mechanism of social media emotional support on RED users’ self-disclosure. A research model involving online emotional support, attachment security, and self-disclosure has been proposed and evaluated. 5.1 Findings The table below shows an overview of hypothesis verification (Table 5.1.1). As can be seen from the results, this study indicates that (1) people's perceived emotional support online has a significant positive effect on their self-disclosure extent; (2) people's perceived emotional support has a positive effect on their attachment security, which in turn affects their self-disclosing behaviors; (3) the level of attachment security plays a partial mediating role in the relationship between perceived emotional support and self-disclosure on social media; (4) people's interaction frequency is significantly related to the perception of emotional support and the general extent of self-disclosure; (5) males show higher scores in emotional support, attachment security, and self-disclosure than females. Table 5.1.1 Results of hypothesis verification 5.2 Interpretation of Findings 5.2.1 Emotional Support on RED The present study investigated sources of emotionally supportive messages on RED and its specific messaging strategies. In general, the emotional support that RED users received is mainly from popular science sharing and delivered through a reflection of feelings like “I understand you” and so forth. Regarding support sources, participants reported that they received emotional support mostly from knowledge-related topics like job seeking and school enrollment, followed by daily sharing and emotional counseling. In contrast to expectations, RED users elicit care and 28 understanding of content related to close relationships the least compared to the other two types. Several possible explanations may account for the results. First, the large number of contents related to shopping advice, life skills, and other useful tips makes it easier for RED users to get access to emotional assistance under those knowledge-based topics. As a platform originating from a consumer community, RED is commonly viewed as a unique search engine by its users to search for assonance from those who encounter the same troubles. In addition, the trait of Chinese people as conservative and implicative also hold back RED users to involve in others' relationship problems. For some Chinese media users, emotional issues should only be discussed privately with close friends or families, resulting in their avoidance of commenting on other people's emotional experiences or sharing their real thoughts publicly on social media. More importantly, exchanging emotional support under more neutral topics reduces the risk of establishing close relationships and maintaining a weak-tie connection with others online, Concerning support strategies, the results of the study indicate that most RED users provide emotional assistance through the reflection of others' feelings, followed by the strategies of self-disclosure and affirmation. It seems that conveying understanding and agreement directly is the most convenient way for one person to show goodwill while preventing information leakage. Unlike this approach, the self-disclosure strategy is less popular among media users since it requires people to tell their stories against human nature to withhold real thoughts in front of a stranger. However, its irreplaceable power in expressing sincerity and sharing companionship still makes it the top 2 choices for people to exchange emotional support in a nonverbal social media context. 5.2.2 The Role of Social Media Emotional Support The present study discussed the role of emotional support in both individuals’ self-disclosure as well as the enhancement of attachment security in online communications. In line with previous works on emotional support (Y. Lin & Chu, 2021; Weber et al., 2004; Zhou, 2017), the findings of this study confirmed a significant positive relationship between people’s perceived emotional support and their self-disclosure on RED. More specifically, it suggests that if one person perceives himself or herself as being adequately emotionally supported, he or she will become more willing to disclose personal stories deeper and with higher frequency. According to the Social Exchange Theory and the Social Penetration Theory, emotional support from 29 interactive partners can encourage one person to reveal more about the self by promoting intimacy and trust. This positive impact of emotional support remains strong within online communications through social media. Prior studies have reported that emotional support from interactive partners online is as effective as that from face-to-face communication to establishing trust and intimacy between unfamiliar people and fostering online self-disclosure (Taddei & Contena, 2013; Y. Lin & Chu, 2021; Zhou, 2017). As Y. Lin and Chu (2021) yielded in the study of Facebook self-disclosure, social media users can be facilitated by a sense of emotional support to engage in online self-disclosing behaviors with meaningful breath and depth. It is also proved that social media emotional support can play an important role in enhancing self-disclosure development. Beyond, since online emotional support can be delivered through self-disclosure, people may be motivated to reveal their details reciprocally as a response to others' self-disclosive emotional support. The results of this study also confirm a positive correlation between social media emotional support and the degree of individuals’ attachment security. To be more specific, it is suggested that the more one persona feels emotionally supported online, the stronger he or she is securely attached to online interactions. In accordance with the present literature, this finding is consistent with previous researchers which demonstrated the significant role of emotional support in promoting attachment (K. Huang et al., 2010; Hunter et al., 2006; X. Ren, 2018). In a study of online support groups, Hunter et al. (2006) indicated that emotional support from online group members can bring comfort and attachment. X. Ren (2018) further claimed that a high frequency of emotional support transformation has a positive effect on enhancing overall satisfaction with the need for autonomy, relatedness, and competence, thus forming strong emotional attachments. In the case of RED, emotional support provided by other users can satisfy all three basic needs (autonomy, relatedness, and competence) respectively through likes, favorites, and comments. In general, this finding not only verifies the positive impact of emotional support on the secure attachment but also explains the reason why people show a strong reliance on social media today. First, seeking emotional support on social media can gather massive responses from others in a relatively short time, which is effective and efficient. Secondly, people can easily connect to those who share similar interests and personalities with the powerful social media network and get access to more emotional support messages. Further, 30 since social media provides people with a weak-tied anonymous environment, individuals can maintain a comfortable emotional distance from others while interacting frequently for support and understanding (Colineau & Paris, 2010). In this case, people can realize their social goals while avoiding the responsibility of maintaining a relationship, thus leading to a sense of security. 5.2.3 Attachment Security and Its Mediation Effect In the current study, the relationship between attachment security and self-disclosure was further examined. As stated by prior works (Keelan et al., 1998; Wei et al., 2005; C. Huang et al., 2019; Mikulincer & achshon, 1991), the results of this investigation agree that people’s attachment security is positively and significantly related to their self-disclosure on social media. Referring to the adult attachment theory, people can be divided into four groups based on different scores on attachment anxiety and avoidance. As explained in the literature review, people who are anxiously attached are characterized by a preoccupation with connection maintenance whereas avoidant people tend to refuse to form close relationships with others. In contrast to these two types, people with a considerable level of attachment security are more likely to positively view themselves as lovable and others as trustworthy (Smith et al., 1999; Oldmeadow et al., 2013). C. Huang et al. (2019) claimed that people with a higher level of attachment security show a stronger desire to develop relationships and share personal stories with partners. This positive relationship between attachment security and self-disclosure not only exists in face-to-face communications but is confirmed within interactions on social media (Grabill & Kerns, 2000; Keelan et al., 1998). Compared to attachment anxiety and avoidance, attachment-secure people feel more comfortable and open to disclosing the self online (Wei et al., 2005). Although the finding in the present study agrees with most works to date, some researchers highlighted a negative relationship between attachment security and self-disclosing behaviors. According to Aharony (2016), people with insecure attachment styles are more likely to reveal personal information on Facebook. A possible explanation for these contradictory results may be the variance in platform atmosphere, which also predict an individual’s willingness to share personal information with others or not. It is reasonable that social media users will tell their stories actively to the public if they perceive the general atmosphere of the platform as friendly 31 and respectful. According to Shan and Yi (2022), a harmonious and fair communicative environment can influence the process of people building mental connections with the platform and further affect their intention to disclose personal information. Another potential reason for the controversy may relate to people’s traits, for example, the Big ive Personality Types. ccording to Hollenbaugh and erris (201 ), individuals’ personality is an important contributor to their disclosure on social media, together with the effect of attachment. Specifically, extravert persons are found to disclose the self in greater amounts and be more likely to form secure attachments within online communications. Compared with previous research in figuring how emotional support can increase attachment security (Hunter et al., 2006; K. Huang et al., 2010) and past examinations in predicting individuals’ self-disclosure through secure attachment (Mikulincer & Nachshon, 1991; Grabill & Kerns, 2000), the present study integrated these findings as to the whole and further explored the role of attachment security within the path from emotional support to self-disclosure. Accordingly, the results of the present investigation suggest that attachment security mediates the correlation between emotional support and online self-disclosure, verifying prior studies’ ideas of emotional elements indirectly affecting people’s media use through attachment (Zhang & Chen, 2022; C. Huang et al., 2019). As Zhang and Chen (2022) reported in the study of social media users' content-sharing behaviors, recognition, and encouragement from other users can enhance people's attachment security by fulfilling basic needs and predict a stronger desire for them to share media content. On the other hand, the finding of attachment security's mediator role also agrees with the concept of social media attachment. Specifically, a secure attachment to social media may appear if one person is assured by others and able to increase their connectedness and presence by publishing media content through the medium (Altuwairiqi et al., 2019). Referring to RED, this process might be triggered by other users responding to one person's comment or RED notes with emotionally supportive messages and ending in the motivation to tell personal stories in return. Those who perceive themselves as adequately emotionally supported on RED are more likely to feel securely attached online and disclose information more no matter in depth or breath. Overall, the verification of attachment security as a mediator highlights the necessity of employing irrational factors to predict one person’s self-disclosure and potential media use. 32 5.2.4 Influence of Interaction Frequency Since media use is associated with people’s perception of emotional support and can predict their future media use (Shensa et al., 2020; Lee et al., 2013; Lee et al., 2013; Lin et al., 2016), it is reasonable to examine how the frequency of people to participate in online interactions can influence their recognition of perceived emotional support and self-disclosure. In this study, interaction frequency is measured by the number of times that people like, favorite, comment, and create media content on RED. In line with a prior study (Shensa et al., 2016), people’s interaction frequency on RED was found to be associated with their perceived emotional support and self-disclosure. It is evident that the more people interact with others online, the more they feel emotionally supported and the more they are willing to disclose information. According to X. Ren (2018), interactions among social media users can facilitate shared emotional experiences and create a sense of belonging which strengthen people's desire for self-expression and sharing personal stories. Traditionally, humans as social animals tend to establish relationships with the external world through communication, in which interacting with verbal and nonverbal messages is a crucial means. In the context of social media, people can get desirable information and get to know each other through frequent interactions, which in turn enhances their perceived level of closeness to strangers. Compared with those who rarely participate in online interactions, people with a higher frequency of communication through likes, favorites, or comments generate stronger feelings of being understood, empathy, and affirmation, thus perceiving emotional support from social media as more adequate. In contrast to the positive correlations between interaction frequency, emotional support, and self-disclosure, the times that people socialize with each other on RED showed no significant association with their degree of attachment security. A possible explanation for this result might be that frequent interactions can only explain a greater number of online communications but fail to ensure good quality of them. To be more specific, one person may like or favorite others' media content many times but have never commented on or produced any posts online, which leads to a lack of two-way interactions and failure to meet three basic needs. In this case, interaction frequency has no obvious impact on the degree of individuals' attachment security. 33 5.2.5 The Gender Matters Genders as a crucial demographic factor are commonly discussed within communication literature. Consistent with previous research (Nelson & Quick, 1991; Cosby, 1973), the results of the current study reported a gender variance in perceived emotional support, attachment security, and self-disclosure. Beyond expectations, male participants who completed the scale reported a higher degree of feeling emotionally supported by others and being securely attached during interactions. A possible explanation for these results may be a discrepancy in emotional support received in offline social life. Compared to females, males receive relatively less emotional support from daily communications due to a conventional view in which men seeking comfort or sympathy is considered to be weak. In this case, male users may become more sensitive and suggestible to emotional support than female users and may report a greater amount of perceived emotional support on RED. Another possible explanation for the covariances lies in the privileges that men enjoy in daily life. Since men are empowered with priorities in society for a long time, they tend to feel less uncertainty in the process of growing up and be securely attached to others in relationships, which also ends in higher attachment security during social media interactions. It is also surprising to find that male RED users have a greater desire to tell personal stories and preferences than their counterparts. Contradict to previous studies indicating females are the ones to disclose themselves more (Snell et al., 1988), men in the current study show a stronger willingness to release private details and share real thoughts on multiple topics. This result may be explained by the fact that males are more narcissistic and used to presenting themselves to others, leading to a higher extent of self-disclosure online (Stokes et al., 1980; Hollenbaugh & Ferris, 2014). In addition, a social tendency of gender equality in which males are encouraged to oppose traditional disciplines of manliness and express emotional demands freely may also contribute to this finding. 5.3 Implications 5.3.1 Theoretical Contributions Theoretically, this study establishes a new self-disclosure model by integrating psychological factors to explore how social media emotional support can influence users’ extent to disclose intimate information about the self on social media. Specifically, the current study synthesizes 34 past work’s conclusions on the role of emotional assistance and examines its indirect effect on individuals’ self-disclosure via attachment security. According to the results, it is noted that irrational motives (e.g., emotional support) are positively correlated with people's activities on social media. This study also revalidates the relationships among online emotional support, attachment, and self-disclosure in a Chinese setting. Prior works have demonstrated that emotional support can enhance relationship quality among online users, foster their intention to continuously use the medium, and encourage them to self-disclosing the self (Liang et al, 2011; Li, 2017; Y. Lin & Chu, 2021). However, most of the emotional support literature centered on Western applications (e.g., Facebook and Instagram); less is known about Chinese social media like RED and examines the effect of emotional support in another cultural background. In this case, the results of this study may enrich the research on emotional support by discussing the unique patterns of Chinese media users and drawing a more general conclusion about the correlation between emotional support on disclosive behaviors. With respect to the implementation of attachment security, the findings extend the application of attachment theory as well as La Guardia's A-R-C model (2000) in explaining the communicative phenomenon. In previous research, the A-R-C model was only used to represent individuals' general emotional attachment toward the platform in examinations of continued use and information-sharing behaviors (X. Ren, 2018; Zhang & Chen, 2022). In this study, participants were surveyed regarding their overall satisfaction with three basic needs (autonomy, relatedness, competence) to provide an overview of how much they can feel securely attached to the facilitation of emotional support during online interactions. Taking advantage of the powerful online network, people can conveniently connect with those who share similar interests and are more likely to believe that only relationships on social media can provide them with favorable sympathy, respect, or patience, which strengthens their attachment to social media (Yue, 2022). 5.3.2 Practical Implications In terms of practical implications, the findings of this study suggest that emotional support from social media plays a vital role in explaining new changes in people's interpersonal communications during post-pandemic times and provides further insights for society, the 35 general public, as well as individuals. Concerning society's benefits, the current study notices the strong power of social media emotional support in changing the online climate and promoting active mass communication. By encouraging emotional support exchanges in online interactions, mainstream media can motivate the passion of the public and generate a sense of resonance as well as belonging. Additionally, since emotional support is positively related to people’s self-disclosure, mainstream media can also facilitate a free-flowing discussion by offering adequate emotional support to the people. In terms of the general public, the findings of this study note that social media emotional support not only activates people’s participation in online activities but serves as a significant predictor of individuals' increasing social media addiction. With the advantages of quantity and efficiency, emotional support from other media users can satisfy people's multiple social needs better compared to that offline partners. By providing a perceived feeling of understanding and comfort, online emotional support helps realize individuals' need for belonging, esteem as well as self-actualization, thus encouraging them to express the self confidently on social media. On the other hand, the positive relationship between emotional support and attachment security also reflects on the fact about lack of emotional assistance in offline interactions. In this case, people are forced to seek accompany from online networks which in turn strengthens their reliance and trust on social media. This study also highlights the irreplaceable value of online emotional support for younger generations today. Growing up with the development of the internet, young people are used to spending more effort in maintaining online relationships and view social media as a tree hole to pour out troubles. In this case, online emotional support has long been an integral part of their social lives to receive desirable responses. Moreover, it also provided young people, who were greatly affected by the only-child policy, with abundant companionship to reduce the loneliness they felt in real life. Apart from the above implications, the study also offers valuable information for both social media users and operators. On the one hand, the results suggest that media users should improve their media intimacy while benefiting from online emotional support and participating in online interactions. Since social media emotional support can also promote people's 36 attachment to the platform, users should also be aware of its harm to exacerbate the addiction to the virtual world and separate them from real life. On the other hand, the findings of this study also offer some advice for media operators to enhance individuals' enthusiasm in public discussion as well as user-generated content creation by making good use of the correlation between emotional support and self-disclosure. 5.4 Limitations and Future Research 5.4.1 Limitations in Research Design The results of this study should be interpreted with caution for multiple reasons. First, most respondents of the present investigation were from the younger generation. Although the ratio of males to females is relatively even, the overall sample is not as representative as designed. Compared to the older generations, this group of people is grown up with the development of the internet, which contributes to their greater desire to seek emotional support and self-disclose on social media. Future studies should attempt to recruit a more comprehensive sample consisting of people from multiple age groups to test the general effect of perceived emotional support on self-disclosure. Second, the measurement of the present work may have a few discrepancies with the original English scales due to linguistic differences. In this case, future studies should invite communication specialists in the preliminary stage and carefully adjust the scales to ensure that participants can understand the actual meaning of each item and complete the questionnaire. Third, the single self-reported instrument in the current study may result in a potential side effect of massive subjective factors such as bias and errors. Different groups of people (e.g., males and females, adolescents and adults) may interpret the survey items in different ways and with different understanding levels. People’s responses may also be affected by the order of survey items and their characteristics. In future investigations, it might be possible to use a combined method of questionnaires and situational experiments to conduct a more precise measurement of people's attitudes toward certain variables. 5.4.2 Prospects for Future Research Apart from the inadequacies in research design, there are several questions thrown up in need of further investigation. Since this study has only examined the effect of perceived emotional support on self-disclosure as well as attachment security, some potential impact factors may be ignored within the current research model. or example, people’s perceived emotional support 37 may also enhance their social media self-efficacy to achieve desirable social goals online and thus strengthen the willingness to disclose while indirectly affecting self-disclosure via attachment security. In this case, more research should be undertaken to examine whether there is another potential path from emotional support to disclosing behaviors. Besides, it is also suggested to involve prior experiences as a control variable in identifying the differences between new and existing users on the perception of social media emotional support as well as the general extent of self-disclosure. 6. Conclusion The current study extends research about online emotional support and social media self-disclosure on a Chinese social media RED as it has integrated attachment security as an irrational factor to explore the impact path from perceived emotional support to online self-disclosure. The study proposed that the former element would affect the latter directly and the relationship between these two would be mediated by the individual's secure attachment. Results of the investigation suggested that (1) people's perceived emotional support on RED is positively related to their extent of self-disclosure; (2) people's perceived emotional support on RED is positively related to the level of attachment security; (3) the level of attachment security is positively related to people's general extent of self-disclosure; (4) attachment security partially mediates the relationship between emotional support and self-disclosure on RED. These findings confirmed prior studies’ identifying a significant positive correlation between emotional support and self-disclosing behaviors and highlighted that adult attachment plays an important role in the influence of emotional factors on individual media use. More specifically, if people are exposed to adequate emotional support and feel comfortable on social media, they may develop a higher level of attachment security while interacting with others, therefore in turn promoting their desire to disclose the self more honestly and frequently. Furthermore, the study presented an overview of emotional supportive messages on RED and reported that knowledge-based topics and lifestyle sharing are better at gathering emotional support from others whereas emotional topics may hinder people's impulsion to exchange support related to actual feelings. Additionally, expressions with greater reciprocity such as reflection of feelings and self-disclosure are the most frequently used strategies for people to 38 offer emotional support compared to other four types. However, this study also has certain limitations in both research procedures and design. First, it fails to recruit as multiple participants as possible during data collection. Since most respondents are from younger generations, different patterns of media use and perceptions toward online emotional support from older age groups may be neglected. Second, data from the present questionnaire in this study may not be as accurate as expected due to a discrepancy between the original English scales and the modified Chinese version. Although this instrument achieved favorable reliability and validity, future studies should ask communication specialists for better suggestions on item setting. Third, this study did not involve objective factors while conducting the research. All data were collected from a single survey instrument by participants self-reporting their experiences and first impressions on certain items. Although the approach is useful for quickly gathering a large amount of information from samples, it can also be biased and prone to errors. Forth, the present study only considered the direct effect of emotional support on attachment security which may ignore certain moderating or mediating factors within the path. Further, it also failed to include prior experience of using RED as a control variable into the research model and did not identify a potential variance in perceived emotional support, attachment security, and self-disclosure between new and existing RED users. In this case, more researches are needed to explore other potential factors within the impact mechanism of emotional support on self-disclosure. Collectively, future studies should not only target the sample carefully and thoroughly but apply a combined method to study the relationship between emotional factors and individual media use. It is also important to incorporate more variables while investigating the effect of emotional support in Chinese social media settings to cope with a more complex and changeable media environment. 39 Acknowledgements I would like to express my deepest appreciation to my supervisor for her professional and timely help with this thesis.
