Similarity between Parent’s and Children’s Coping with Childhood Cancer Ellen K. Williams Thesis completed in partial fulfillment of the requirements of the Honors Program in the Psychological Sciences Under the Direction of Prof. Bruce E. Compas Vanderbilt University 2 April 2012 SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 2 Abstract Objective. Childhood cancer diagnoses and treatment presents challenges and sources of stress for both children and their parents in related domains. It is important to understand how parents and children cope with the child’s cancer. The current study will examine the degree of similarity in ways of coping in a sample of children with newly diagnosed cancer and their parents. Methods. Children and adolescents (5 to 17years-old; N = 334) and their parents were recruited near the time of a child’s diagnosis or relapse of cancer. Children, mothers, and fathers completed measures on coping at home or in the hospital/clinic. Results. Mother’s coping was significantly related to children’s coping with 6 of the 9 significant correlations (r’s ranged from -.24 to .31, p < .05 or p < .01). There was no significant relationship between father’s and children’s coping. Linear multiple regression analyses indicated that there was a unique effect of secondary control between mothers and children. Conclusions. There is a relationship between mother’s coping and children’s coping, which suggests that there may be benefit in teaching parents coping strategies in interventions to improve children’s coping with cancer. SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER Introduction Over 12,000 children and their parents are faced with significant stress associated with a cancer diagnosis and treatment annually in the U.S, with cancer also being the second highest cause of death for children (Jemal, Siegel, Xu, & Ward, 2010). Parents and children are faced with a variety of different stressors caused by cancer, including disruptions in daily/role functioning, physical effects of treatment, uncertainty about the disease and treatment, and the fear and threat of death (Rodriguez, Dunn, Zuckerman, Vannatta, Gerhardt, & Compas, 2012). With these high levels of stress, it is important to understand how parents and their children cope with the child’s cancer. Theories of the socialization of coping propose three alternative models for how children’s adaptations to stressors are affecting the family, including coaching, modeling, and family context (Kliewer, Sandler, & Wolchik, 1994). These models suggest that parent’s coping with the child’s cancer will affect how the child copes with cancer, but there is a lack of research about this relationship. However, previous research has not examined the relations between the ways that children and parents cope with the stress associated with a child’s cancer. The current study will examine the degree of similarity in ways of coping in a sample of children with newly diagnosed cancer and their parents. Children with Cancer Childhood cancer diagnoses and treatment presents challenges and sources of stress for both children and their parents (Kupst & Bingen, 2006). A recent study by Rodriguez et al. (2012) examined stressors faced by children and their mothers and fathers in several domains. For children, stressors include daily/role functioning 3 SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 4 (missing school or falling behind in school work, not being able to do the things that children used to do, frequent hospital or clinic visits, concerns about family and friends), physical effects of treatment (feeling sick from treatments, changes in appearance, pain and soreness from medical procedures), and uncertainty about cancer (not understanding medical professionals, confusion about cancer, and concerns about the future). Daily/role functioning stressors were most frequently rated as stressful from self-reports from children, whereas parents rated children’s physical effects stressors as more stressful than role functioning stressors. Parents cancer-related stressors included daily/role functioning (paying bills and family expenses, concerns about job, having less time and energy for other family members, cancer communication (talking with child about cancer, talking with family and friends about cancer, understanding information about cancer and medical treatment, arguing with child about taking medicines and other treatment), and cancer caregiving (not being able to help child feel better, the effects of child’s treatment, not knowing if child’s cancer will get better). Caregiving stressors were rated as somewhat or very stressful by 88% of mothers and 74% of fathers and levels of this type of stress were associated with higher levels of emotional distress. The high levels of stress related to cancer both for parents and children indicate that it is important to understand how parents and children cope with this stress. Understanding how parents and children cope with childhood cancer, and how their coping relates to each other has important implications for interventions as well as greater understanding of possible mechanisms in the development of coping during childhood and adolescence. SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 5 Coping There is considerable debate and discussion surrounding how coping is defined, although a consensus is emerging. As defined by Compas, Jaser, Dunn, and Rodriguez (2012), “coping can be viewed as a collection of purposeful, volitional efforts that are directed at the regulation of aspects of the self and the environment under stress.” Eisenberg, Fabes, and Guthrie (1997) describe coping as “involving regulatory processes in a subset of contexts— those involving stress” (p. 42). Skinner and Wellborn (1994) define coping as “an organizational construct, which describes how people regulate their own behavior, emotion, and motivational orientation under conditions of psychological distress” which includes how people “mobilize, guide, manage, energize, and direct behavior, emotion, and orientation, or how they fail to do so” under stressful conditions (abstract, p. 113). Compas, Connor-Smith, Saltzman, Thomsen, and Wadsworth (2001) define coping as, “conscious and volitional efforts to regulate emotion, cognition, behavior, physiology, and the environment in response to stressful events or circumstances” (p. 89). These definitions all focus on how coping involves the regulation of psychological and behavioral processes. The emerging definition of coping allows coping to be researched more completely and its importance to be understood. There is also debate on how coping should be measured. Compas et al. (2012) state that, “in their comprehensive review of over 400 subtypes of coping that have appeared in research on coping, Skinner, Edge, Altman, and Sherwood (2003) identified only four frameworks for classifying subtypes of coping that have been empirically tested and validated (Ayers, Sandler, West, & Roosa, 1996; Connor-Smith, Compas, SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 6 Wadsworth, Thomsen, & Saltzman, 2000; Tobin, Holroyd, Reynolds, & Wigal, 1989; Walker, Smith, Garber, & Van Slyke, 1997).” Of those that have been empirically tested and validated, only Connor-Smith et al. (2000) and Walker et al. (1997) have been used for children and adolescents coping with illness (Connor-Smith et al. 2000, Walker et al., 1997). Compas et al. (2012) identified multiple common factors between these frameworks, including factors identifying different types of coping. Each framework had a dimension of active or primary control coping, which includes a direct effort to change the source of stress or one’s response to the stressor. The frameworks also had a dimension related to accommodative or secondary control coping, which includes adapting to stress through “reappraisal, positive thinking, acceptance, or distraction” (Compas et al., 2012, p. 461). The third factor of coping presented is passive, avoidant, or disengagement coping, which includes avoidance of the source of stress (Compas et al., 2012). These frameworks have been widely used to study coping with a variety of different stressors. The framework developed by Conner-Smith et al. (2000) divides coping into three specific factors with common techniques that are used within the factor, and has previously been used to study children with illnesses. The factors are primary control coping (problem solving, emotional expression, emotional regulation), secondary control coping (cognitive restructuring, positive thinking, acceptance, distraction), and disengagement coping (wishful thinking, avoidance, denial) (Connor-Smith et al., 2000). The type of coping technique used by children and adolescents is related to psychological and physiological processes, including anxiety, depression, aggression, and positive mood. For example, the use of secondary control coping in response to SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER stressors associated with parental depression was associated with lower internalizing and externalizing symptoms (Langrock, Compas, Keller, Merchant, & Copeland, 2002). In addition, secondary control coping was related to a decrease in anxious/depressed symptoms and aggressive behavior in response to parental depression and interparental conflict (Fear et al., 2009). Increased levels of observed positive mood and lower levels of affective problems were also associated with the use of secondary control coping (Jaser, Champion, Dharamsi, Riesing, & Compas, 2011). The results also suggested that positive mood created a resilient affect, showing the importance of primary and secondary control coping in increasing positive affect and decreasing affective problems. In a recent study by Compas, Desjardins, Gerhardt, Vannatta, Young-Saleme, Rodriguez, Dunn, and Snyder (2013), secondary control coping was found to have the most consistent association with emotional distress and was related to lower levels of anxiety and depression for children with cancer. In contrast to secondary coping techniques, disengagement coping has been found to be associated with lower levels of positive mood and higher levels of affective problems (Jaser et al., 2011). Disengagement coping is also associated with higher behavioral emotional responses and higher levels of depressive symptoms (ConnorSmith et al., 2000; Fear et al., 2009). The use of primary control coping is associated with higher positive mood, but it may be a more effective form of coping when the individual perceives or has some degree of control over the problem or stressor (Jaser et al., 2011). Development and Socialization of Coping 7 SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER Zimmer-Gembeck and Skinner (2011) reviewed and critiqued research on the development of coping across childhood and adolescence. Zimmer-Gembeck and Skinner identified what coping techniques were most commonly used for each age group. They noted that research suggests that young children primarily seek support from adults or use active behavioral forms of coping to get what they want, overcome obstacles, distract themselves, or withdraw from stressful situations. In middle childhood, Zimmer-Gembeck and Skinner note that children become more self- reliant and their coping strategies become more differentiated and complex. For adolescents, “instrumental action is supplemented by planful problem-solving, which is among the most common strategies adolescents report using when they encounter challenges. Distraction tactics also become more diverse; compared to children, adolescents more often draw upon both behavioural and cognitive strategies” (Zimmer-Gembeck & Skinner, 2011, p. 12). However, these patterns of the development of coping do not explain how children learn how to cope, or explain the effect parent’s coping abilities has on children. One model of how children learn to cope is the socialization of coping. The socialization of coping proposes three alternative models for how children’s adaptations to stressors affect the family, including coaching, modeling, and family context (Kliewer et al., 1994). Coaching is the parent’s direct instruction or assistance on how to appraise stressful events and deal with problems. Modeling is the parents’ own response to stressful situations and how these affect children’s appraisals of stressful events, and includes watching and imitating parental responses. Family context is how the parents provide and shape the family environment, including 8 SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 9 stability, family cohesion, the parent-child relationship, acceptance and warmth, and authoritative parenting styles (Kliewer et al., 1994). In a more recent study, Kliewer, Parrish, Taylor, Jackson, Walker, and Shivy (2006), examined the influences of the caregiver for the socialization of coping with regard to community violence. The study presented different models and their implications with models predicting problemfocused coping, avoidance-distraction coping, proactive actions coping, aggressive coping, and arousal reduction coping. Modeling, coaching, and family context each contributed to the reports of coping by children, with problem-focused coping having the strongest associations with changes in adjustment. For example, in the model predicting problem-focused coping, more educated caregivers who encouraged active coping were more likely to support problem-focused coping (Kliewer et al., 2006). Also for the model predicting proactive coping, encouragement to proactively avoid situations created feelings for the child that they were loved, valued, and accepted by their caregiver (Kliewer et al., 2006). Coping with Cancer Childhood cancer is stressful for the entire family, and parents and children face stress in similar domains, including daily/role functioning, communication about cancer, and fear about the future. Parents are also involved in their child’s cancer treatment, so they are aware of the stress in their child’s life. Children with cancer and their parents provide a potentially interesting sample to study coping because of the similarities in the source of stress. Since parents and children are facing similar stress from cancer, this provides an opportunity for children to observe how their parents cope as well as be coached by their parents for how they should cope with cancer. SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 10 Modeling, coaching, and family context all potentially influence how children learn to cope with cancer, so the children with cancer and their parents provide a unique sample to see how parents’ and children’s coping are related and to see if parents and children cope similarly to childhood cancer. However, as noted above, these potentially important processes have not been examined in previous research on children coping with cancer. Hypotheses Modeling, coaching, and family context are impacted by how the parent themselves cope with stress. With a parent modeling and coaching certain coping techniques, we hypothesize that children will cope similarly to their parents. For example, mothers’ primary, secondary, and disengagement coping will be positively correlated with children’s primary, secondary, and disengagement coping respectively. We also hypothesize that children will cope more similarly to their parents as children move from childhood into adolescence. Method Participants Participants were 483 parents, including 317 mothers and 166 fathers of 334 children with cancer. Within this group of mothers and fathers, there were 153 couple dyads (i.e., data were collected from both the mother and the father of the child). Participants were recruited from pediatric cancer registries at two hospitals in the Midwestern and Southern United States. Eligibility criteria included children who (a) were ages 5–17 years old; (b) had a new diagnosis or relapse/recurrence of initial cancer diagnosis (i.e., child’s treatment progressed to maintenance phase or further and SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 11 initial diagnosis recurred) within the previous 6 months; (c) were actively receiving treatment through the oncology division; and (d) had no preexisting developmental disability. Parents consented to participate in the study between 0 and 6 months after their child’s diagnosis or relapse (M = 1.4 months, SD = 1.2) and returned questionnaires between 0 and 9 months after their child’s diagnosis (M = 2.4, SD = 2.1). Families of children with new diagnoses comprised 88.9% of the sample; there were no significant differences in enrollment or completion time based on the child’s first-time diagnosis versus relapse status. Reports were obtained from all of these parents about their children’s coping and emotional distress, and child self-reports were obtained from 116 adolescents (ages 10-17 years old) who were old enough to complete the self-report measures used in this study. This subset of children was on average 13.5 years old (SD = 2.5), and 54.3% (n = 63) were female. For all families included in the study (see Table 1), children were on average 10.6 years old (SD = 3.9), and 51.8% (n = 170) were male. Children had diagnoses of leukemia (37%; n = 120), lymphoma (26%; n = 84), brain tumor (8% n = 26), and other solid tumors (e.g., osteosarcoma, Wilm’s tumor; 30%; n = 98). Thirty-seven children (11%) were recruited into the study following a relapse of their original cancer. For the subgroup of children who were old enough and provided self-report data, children were on average 13.4 years old (SD = 2.4); 48% (n = 76) male; 90% (n = 141) White/Caucasian, 8% (n = 12) Black/African-American, and 2% (n = 4) other. They had diagnoses of leukemia (33% n = 51, lymphoma (34%; n = 53), brain tumor (5%; n = 7), and other solid tumor (29%; n = 46). Sixteen (10%) were children with relapsed SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 12 disease. Mothers were on average 37.5 years old (SD = 7.1), and fathers were 39.5 years old (SD = 7.7). Race and ethnicity of the parents was 86.5% (n = 418) White/Caucasian, 8.9% (n = 43) Black/African-American, 0.8% (n = 4) Asian-American, 0.2% (n = 1) American Indian/Native Alaskan, and 3.3% (n = 16) other. The families represented a variety of annual income levels: 27.7% (n = 91) earned $25,000 or less, 28% (n = 92) earned $25,001-$50,000, 14.3% (n = 47) earned $50,001-$75,000, 11.6% (n = 38) earned $75,001-$100,000, and 14.9% (n = 49) earned over $100,000. Measures Demographic and Medical Data. Parents provided demographic information including age, education level, race, family income, and marital status. Participants gave permission for the research staff to access medical data, where the child’s diagnosis/relapse status was extracted. Children’s coping. The Responses to Stress Questionnaire-Pediatric Cancer version (RSQ-PC; Connor-Smith et al., 2000; Miller et al., 2009; Rodriguez et al., 2012) was used to obtain adolescents’ self-reports and mothers’ and fathers’ reports of their children’s coping with cancer. The RSQ-PC Version includes a list of 12 cancer-related stressors (e.g., missing school, frequent hospital or clinic visits, changes in personal appearance), and 57 items reflecting voluntary (coping) and involuntary (automatic) stress responses of children/adolescents in response to cancer-related stressors. For the purpose of this study, only the three voluntary coping scales are reported. The coping scales include: primary control coping (i.e., problem solving, emotional modulation, emotional expression), secondary control coping (i.e., acceptance, cognitive SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 13 restructuring, positive thinking, distraction), and disengagement coping (i.e., avoidance, denial, wishful thinking). To control for response bias and individual differences in base rates of item endorsement, proportion scores were calculated by dividing the total score for each factor by the total score for the entire RSQ (Osowiecki & Compas, 1998, 1999; Vitaliano, Maiuro, Russo, & Becker, 1987). In the current sample, internal consistencies of children’s self-reports (ages 10-17) were: primary control = 0.81, secondary control = 0.84, and disengagement = 0.82. Internal consistencies for mother and father parent reports, respectively, were: primary control = 0.66/0.74, secondary control = 0.87/0.85, and disengagement = 0.71/0.69. The factor structure of the RSQ has been supported in confirmatory factor analytic studies with children and adolescents from a wide range of ethnic and cultural backgrounds coping with a wide range of stressors (e.g., Benson et al., 2011; Compas et al., 2006; ConnorSmith et al., 2000; Connor-Smith & Calvete, 2004; Wadsworth, Reickmann, Benson, & Compas, 2004; Yao et al., 2011). Parents’ Coping. Participants completed a version of the Response to Stress Questionnaire (RSQ; Connor-Smith et al., 2000) that is designed to assess coping responses to stressors related to having a child with cancer. The RSQ includes 57 items on which participants indicate on a 4-point scale how much they use various coping methods, from 0 (not at all) to 4 (a lot), in response to stressful aspects of their child’s cancer (e.g., “Not knowing if my child’s cancer will get better,” “Understanding information about cancer and medical treatments”). Factor analyses of the RSQ have identified five factors: primary control engagement coping (problem solving, emotional expression, emotional modulation), secondary control engagement coping (cognitive SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 14 restructuring, positive thinking, acceptance, distraction), disengagement coping (avoidance, denial, wishful thinking); two additional scales that reflect involuntary stress responses were not used in the current analyses. The RSQ has been shown to have good psychometric properties (Connor-Smith et al., 2000). Internal consistencies for this sample for each of the factors of interest ranged from = .75 to = .79 for mothers and from = .74 to = .76 for fathers. Proportion scores were created by dividing the total score for each factor by the total score for the RSQ (Connor-Smith et al., 2000) and were used in the current analyses to control for response bias. Means and standard deviations were calculated for mothers’ and fathers’ Primary Control Coping, Secondary Control Coping, and Disengagement Coping ratio scores, and for mothers’ and fathers’ depressive, anxiety, and PTSS symptoms. Procedure Parents were identified from cancer registries at the two hospitals in the Southern and Midwestern United States and approached in the outpatient hematology/oncology clinics or in inpatient rooms by a member of the research team. The staff member introduced the study, explained that the goals of the study were to help medical personnel and future families of children and youth with cancer better understand how families coped with the stress of a cancer diagnosis and treatment, and assessed parents’ interest in participating. Variation in the time at which parents were first approached by the research team occurred based on the timing of communication of the diagnosis from the medical team, parents’ availability to hear about the study, and parents’ needing time to consider the study before consenting. After providing informed consent during a visit to the hospital, parents were given questionnaire SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 15 packets that they completed in the hospital, outpatient clinic, or took home and returned at a subsequent visit. In the case that only one parent was present and another parent or caregiver was involved, consent forms and questionnaires were sent home for the other caregiver to consider. Parents consented to participate in the study between 0 and 6 months after their child’s diagnosis or relapse (M = 1.4 months, SD = 1.2) and returned questionnaires between 0 and 9 months after their child’s diagnosis (M = 2.4, SD = 2.1). Families of children with new diagnoses comprised 88.9% of the sample; there were no significant differences enrollment or completion time based on the child’s first-time diagnosis versus relapse status. Families were compensated $50 when at least one parent completed the measures. The Institutional Review Boards at both sites approved the study protocol. Statistical Analyses Pearson correlation coefficients and linear regression analyses were conducted to evaluate associations between mothers’ coping, fathers’ coping, and children’s coping. Results No significant differences were found between sites for age of child, type of tumor, time since diagnosis, and coping ratio scores. Therefore, all analyses included combined data from both sites. Descriptive statistics Means and standard deviations are presented in Table 2 for mothers’ and fathers’ reports of coping on the RSQ and children’s self report on coping on the RSQ. Mothers’, fathers’, and children’s reports of coping are reported as proportion scores to SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 16 control for response bias and individual differences in base rates of item endorsement. The proportion scores were calculated by dividing the total score for each factor by the total score for the entire RSQ. The proportion scores were normally distributed, with no skewness towards zero. Correlational analyses Bivariate correlations of mothers’, fathers’, and children’s’ self-report of coping are presented in Table 3. As hypothesized, mother’s coping was significantly related to children’s coping. For the nine correlation values between mother’s coping and children’s coping, 6 of the 9 correlations were significant (r’s ranged from -.24 to .31, p < .05 or p < .01). Specifically, mothers’ secondary coping was significantly associated with children’s secondary coping (r = .31, p < .01). In addition, mothers’ disengagement coping was significantly correlated with children’s disengagement coping (r = .19, p < .05). However, fathers’ coping had no significant associations with children’s coping. The correlations did fit the same trend as mothers’ coping and children’s coping. Disengagement coping was negatively associated with primary and secondary coping (r’s ranged from -.22 to .25), but these correlations were not significant, perhaps due to the smaller sample of fathers in the study and the relatively lower statistical power than in the sample of mothers and children. Correlations between mothers’ and fathers’ coping and children’s coping while accounting for age is presented in Table 4. Children who had completed the self-report of the RSQ were split into a younger and older group based on the median of 169 months or 14.1 years. There is no difference in the magnitude of the correlations for younger and older children based on Fisher’s z tests with z’s ranging from 0 to 1.31 SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 17 with no significant differences. Younger children had 3 of the 9 correlations between mother’s coping and children’s coping as being significant, with the greatest of those being between mother’s secondary control coping and children’s secondary control coping (r = .36, p < .01). For the older children, only 1 of the 9 correlations between mother’s coping and children’s coping was significant; the correlation between mother’s secondary control coping and children’s disengagement coping (r = -.29, p < .05). These correlations do not support the hypothesis that with age, children’s coping will become more similar to their parents, but the sample is limited by the child self report only being able to be given to children between the ages of 10 and 17. Regression Analyses There were multiple significant relationships between mothers’ self report of coping and children’s self report of coping; 6 of 9 correlations were significant with all types of coping having significant associations with children’s coping. Linear multiple regression analyses were conducted to examine the associations of all three types of mother’s coping when entered together in models predicting children’s coping. Since there were no significant correlations for father’s self report of coping and children’s self report of coping, linear multiple regressions were only conducted for children and mothers. For the model predicting child report of secondary control coping, the overall equation was significant, F (3, 107) = 4.06, p < .01, adjusted R2 = .37. Mother’s secondary control coping ( = .23, p < .05) was a significant predictor of child selfreported secondary control coping; primary control and disengagement coping were not significant predictors for children’s secondary control coping, and there were no SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 18 significant predictors of mother’s coping for children’s primary and disengagement coping. Discussion The diagnosis and treatment of cancer present both parents and children with challenges and sources of stress related to the disease, its treatment, disruptions in daily life, and fears about the future. Understanding how parents and children cope with the stress of cancer and how coping relates is important for providing interventions to enhance effective adaptation to cancer. Previous research provides models of how parents might influence children’s coping and how children learn to cope, for example, through modeling and coaching from the theory of the socialization of coping (Kliewer et al., 1994). The current study examined how parents and children coping are related, and there has been no research that has looked at how parents and children cope with a child having cancer. The current study is one of the first to use a control-based model to study children’s and parent’s coping with cancer by examining primary control, secondary control, and disengagement coping. To determine how parents’ and children’s coping relates, correlations and linear regressions were preformed. Mothers’ and children’s coping were significantly related, with 6 of 9 correlations being significant (r’s ranged from -.24 to .31, p < .05 or p < .01). There were no significant relationships between fathers’ coping and children’s. However, the correlations for fathers were a similar magnitude as mothers. The fewer number of fathers created a lack of power that could have hidden potential relationships. One of the weaknesses of the study was the small number of fathers. SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 19 In the linear multiple regression analyses for mothers’ coping predicting children’s coping, there was a significant relationship between mothers’ secondary control coping and children’s secondary control coping. This demonstrates a unique effect of secondary control coping between mothers and children. Previous research suggests that secondary control coping has a significant relationship with distress and symptoms of anxiety and depression (Compas, Desjardins et al., 2013). The relationship between mothers’ and children’s secondary control coping has implications for the importance of secondary control coping in interventions. Since there is a relationship between mothers’ coping and children’s coping, it may be important to ensure that interventions teach coping strategies not only to children, but also to their parents. Our study had several limitations that need to be addressed in future research. First, this study was cross-sectional, and it will be important to examine the association between parents’ and children’s coping using prospective longitudinal designs. Second, our sample was limited by the age at which children can use a self-report of coping and fill out the RSQ. To include children under the age of 10, future research should ensure that there is another informant to report on young children’s coping. Third, our sample was somewhat limited with regard to ethnic and racial diversity; future studies of children’s coping with cancer with more diverse samples are needed. The findings from this study have implications for future research. The current study looked at how parents’ and children’s coping relates, but it does not study how children learn to cope. There are opportunities for future research to study how children learn to cope with cancer and other stress and the influence parent’s coping SIMILARITY BETWEEN PARENT’S AND CHILDREN’S COPING WITH CHILDHOOD CANCER 20 has on that learning. Future research should also examine the relationship of fathers’ coping and children’s coping. The trends in correlations found in this study suggest that there could be significant relationships that could be studied in the future. Future research should also examine the effect that both parents have on children together. If both parents use and promote one coping strategy, there could be a different effect on the child. Since parents coping strategies are related to each other, the effect that both parents have on children should be examined further (Compas, Bemis, Gerhardt, Vannatta, Dunn, & Rodriguez, 2013).
