Proceedings of 23rd International Business Research Conference 18 - 20 November, 2013, Marriott Hotel, Melbourne, Australia, ISBN: 978-1-922069-36-8 Understanding Consumers’ Intention in Socially Responsible Purchasing in Malaysia Using the Theory of Reasoned Action Victor Ong, Ho Ooi Tim, Liew Chiu Limn and Liew Wei Chyi Past researches have demonstrated the effectiveness of theory of reasoned action (TRA) model to predict consumers’ purchase intention. However, many researches scarcely use a psychosocial perspective to predict consumers’ purchase intention. Hence, this study extends existing researches by incorporating moral norms to gain a better understanding of consumers’ purchase intention for ‘socially responsible’ products in the Malaysian marketplace. Results from this particular study indicate that attitudes towards behaviour in TRA exercise a larger influence in predicting consumers’ purchase intention while personal norm has the highest correlation with purchase intention and it indirectly influences the relationship of subjective norm and purchase intention. From the findings, it is recommended that companies (and even the government) encourage socially responsible purchasing through holding more public activities, creating social expectations, better disclosures of corporate social responsibility and providing education regarding socially responsible purchasing. JEL Codes: M31 1.0 Introduction Corporate Social Responsibility (CSR) is becoming more important that many companies have started to focus on improving CSR. The trend of pursuing CSR may be due to the contribution of researches that suggested CSR can lead to positive brand attitudes and therefore increases consumers‟ purchase intention. Sen and Bhattacharya (2001) argued that CSR can influence consumers‟ purchase intention directly and indirectly. CSR also improves long term profitability (Rashid & Ibrahim, 2002). Another benefit for companies that adopt CSR is the enhancement of corporate reputation and goodwill (Holmes, 1976). Furthermore, it is found that consumers prefer to buy products from companies that possess good CSR and willing to pay more for it. On the other hand, CSR can bring negative impacts to companies if consumers think that the companies focus only on profits (Chakraborty et al, 2004). _______________________________________________________________________ Victor Ong, Sunway University Business School, Sunway University, MALAYSIA.

However, companies are facing challenges due to changes in consumer preferences, unfavorable consumer perceptions of socially responsible products and the high cost to invest in CSR activities (Tan and Lau, 2010). Hence, it is very important for companies to know more about consumer behaviour in order to stand out in the market. The concepts of consumer behaviour were derived from psychological and behavioural studies. In order to understand consumer behaviour, Fishbein and Ajzen‟s theory of reasoned action (TRA) will be used. However, each individual will behave differently when making purchasing decision on socially responsible products as consumers may have different moral obligations. Some studies showed that personal-related constructs should be included in the model to explain individual differences (Bamberg and Moser, 2007). Therefore, personal normative concerns were included in this study to have a better understanding on consumers‟ purchase intention. The research questions in this study were: 1. How does TRA model predict Malaysian‟s purchase intention in socially responsible products? 2. How does the extended TRA model with inclusion of personal norms predict Malaysian‟s purchase intention in socially responsible products? The main objective of this study is to understand the variables that affect consumers‟ purchase intention in socially responsible products by using TRA. Our sub-objectives of the research are: 1. To understand the relationship between CSR and consumer behaviour. 2. To understand the influences of personal norms on purchase intention in socially responsible products. Findings in this study are important for companies in Malaysia. By using TRA to understand consumer behaviours, companies can determine which variables will affect consumers‟ purchase intention. Therefore, this study provides evidences for companies to decide whether to pursue CSR activities or not and provides guidelines for the government and other interested parties to improve the practices of socially responsible purchasing in Malaysia. 2.0 Literature Review 2.1 CSR and Socially Responsible Purchasing One of the pioneers of corporate social responsibility studies, A.B. Carroll (1991) defines CSR as “The total corporate social responsibility of business entails the simultaneous fulfilment of the firm‟s economic, legal, ethical and philanthropic responsibilities. The firm with good CSR should strive to make a profit, obey the law, be ethical, and be a good corporate citizen”. 2 Proceedings of 23rd International Business Research Conference 18 - 20 November, 2013, Marriott Hotel, Melbourne, Australia, ISBN: 978-1-922069-36-8 Socially Responsible Products (SRPs) or Prosocial Products are the products which were produced by companies and sold in order to sponsor or support certain non-profit groups or social causes. Socially Responsible Purchasing refers to consumers‟ behaviour in purchasing causerelated products as a reward for companies‟ CSR (Jia, 2010). A recent research found that consumers are becoming more interested in ethical and socially responsible products (Trudel and Cotte, 2009). Harrison et al. (2005) also found that consumers are now more engaged in purchasing socially responsible products. For example, consumers are now demanding ethical products such as fair-trade products (Nicholls and Opal, 2005). In addition, Creyer (1997) found that consumers will take the ethical dimension of a firm‟s behaviour into consideration when they make the purchase decision, and they were willing to pay a premium price as a reward for the latter‟s ethical conduct. 2.2 Theory of Reasoned Action and Purchase Intention The theory of reasoned action (TRA) is a theory to explain how was a consumer led to a certain buying behaviour (Fishbein, 1980 cited by Choong, 1998). The theory asserts that there are two variables affecting consumer‟s behavioural intention (Choong, 1998). Lutz (1991 cited by Choong, 1998) offered two important propositions in the theory of reasoned action. First, it is necessary to measure a person‟s attitude towards behaviour in order to predict a specific purchase behaviour. The second determinant of the behaviour would be subjective norm, which is the social influence on a person‟s behaviour. Research done by Thompson et al. (1994) found that attitude towards behaviour, subjective norm, and another factor in the extended theory of planned behaviour which is perceived behavioural control, explained a 40-50 percent of variance in behavioural intentions and the intentions explain 19-38 percent of variance in behaviour. However, we focus only on attitude towards behaviour and subjective norm and will be looking into only one aspect in behaviour which is consumer purchase intention in this research, that is a combination of attitude towards behaviour and subjective norm will predict consumer purchase intention. H1: Theory of reasoned action is a prediction model of purchase intention 2.3 Attitude towards Behavior According to TRA, attitudes are a function of beliefs. Suddin Lada et al. (2009) further explained attitude towards behaviour as “a person who believes that performing a given behaviour will lead to mostly positive outcomes will hold a favourable attitude toward performing the behaviour, while a person who believes that performing the behaviour will lead to mostly negative outcomes will hold an unfavourable attitude.” For instance, religion dictates why Muslims have a favourable attitude regarding their purchase intention of halal food. In the same research, Suddin Lada et al. (2009) also found that attitude is positively related to purchase intention of halal food. Researches too found that when consumers have a positive attitude towards environmentally friendly products, their purchase intention of the products will more likely to be positive (e.g. Alwitt and Pitts, 1996). Additionally, Kim et al. (2003) cited by Hustvedt (2006) measured customers‟ 3 Proceedings of 23rd International Business Research Conference 18 - 20 November, 2013, Marriott Hotel, Melbourne, Australia, ISBN: 978-1-922069-36-8 attitudes towards online apparel shopping. They found that attitudes significantly predicted purchase intention of online apparel. On the other hand, it is also found that consumer‟ attitudes toward CSR programs predicted their purchase intention of the company‟s products (Dodd and Supa, 2011). H2: Attitude towards behaviour significantly predicts consumer‟s purchase intention 2.4 Subjective Norm Suddin Lada et al. (2009) define subjective norm as “a person‟s perception of the social pressure put on him/her to perform or not to perform the behaviour in question.” Subjective norm is also a function of beliefs that is predicted by normative beliefs that what other relevant people would advise (Thompson and Thompson, 1996). For instance, a person will receive social pressures to act accordingly when people whom he/she is motivated to comply thinks that he/she should perform the behaviour. Some examples of social norm would be parental influence, peer influence etc. Cotte and Wood (2004) found that parental influences will exist in the consumer‟s purchase decision making process and will also shape their children‟s behaviour. Parents who have a strong desire in purchasing material goods will also cause their children to value material goods in a similar way (Chaplin and John, 2010). On the other hand, Wouters et al. (2010) cited by Barua Promotosh (2010) found that peer influence will positively influence consumers‟ behaviour regarding their consumption patterns of snacks and soft drinks. In addition, it is found that teenagers don‟t even think twice about paying a higher price if their peers think that fashion products are cool (Grant & Stephen, 2006). Moreover, mass media also influences people‟s behaviour. Gullen and Johnson (1986) conducted a study on short term advertising and its impacts on sales and they found that short term advertising have a strong impact on sales. In general, subjective norm will influence consumer‟s behaviour. Sparks and Shepherd (1992) cited by Hustvedt and Dickson (2009) found that subjective norm is a good predictor of consumer‟s intention to eat organic vegetables in the near future. Besides that, Kim et al. (2003) cited by Hustvedt (2006) found that subjective norm significantly predicted consumer‟s intention in online apparel shopping. H3: Subjective norm significantly predicts consumer‟s purchase intention 2.5 Personal norm Ajzen (1991) states that: “The theory of planned behaviour is, in principle, open to the inclusion of additional predictors if it can be shown that they capture a significant proportion of the variance in intention or behaviour after the theory‟s current variables have been taken into account.” Personal norm is defined as “an evaluation of the specific 4 Proceedings of 23rd International Business Research Conference 18 - 20 November, 2013, Marriott Hotel, Melbourne, Australia, ISBN: 978-1-922069-36-8 behaviour in relation to a specific internal standard” (Hustvedt, 2006). Described in a simple way, personal norm is the moral beliefs. Manstead (2000) cited by Jia (2010) included moral obligation measure in the regression equation and it is found that the inclusion of personal norm significantly improved the prediction of intentions than just by attitudes and subjective norms. Harland et al. (1999) cited by Hustvedt (2006) also concluded that including personal norm in the prediction model will improve the prediction of a person‟s behaviour and intention. Dean et al. (2008) cited by Jia (2010) also revealed the important influence of moral concern on purchase decision in the context of organic food. H4: Personal norm significantly predicts consumer‟s purchase intention 2.6 Mediating Role of Personal Norm Bamberg and Moser (2007) found that subjective norm is directly associated with personal norm and it was an indirect determinant of intention. Besides that, Taute and McQuitty (2004) found that personal norm mediated the relationship between social norms and respondents‟ behaviour in making donation. Hence, personal norm has a mediating effect between social norms and purchase intention. H5: Personal norm mediates the relationship between subjective norm and purchase intention The Five Hypotheses in This Research Produced the Framework Below: H1 THEORY OF REASONED ACTION Attitude towards the behaviour H5 Subjective norm H2 H3 Purchase intention of socially responsible product H4 Personal norm Diagram 2.1 Research framework 5 Proceedings of 23rd International Business Research Conference 18 - 20 November, 2013, Marriott Hotel, Melbourne, Australia, ISBN: 978-1-922069-36-8 3.0 Methodology 3.1 Instrumentation The questionnaires include three major sections. Section A gathers data on theory of reasoned action which will be used to assess consumers‟ intention in socially responsible purchasing. An instrument of 10 items which is adapted from Jia (2010) was used to measure attitude towards the behaviour and subjective norm; and an instrument of 6 items which is adapted from Hustvedy and Dickson (2009) was used to measure personal norm. Section B gathers data of consumers‟ purchase intention. An instrument of 5 items which is adapted from Theofilou and Jerofejeva (n.d.) was used to measure consumers‟ purchase intention. Each construct was designed using a 5-point Likert scales. Lastly, section C comprises demographic information of respondents which are gender, age, race and education and a screening question.

However, only 178 questionnaires were used as 24 questionnaires were incomplete and 48 questionnaires were omitted as respondents did not engage in socially responsible purchasing before. From the 178 data, there were 95 female participants (53.4%) and 83 male participants (46.6%). 3.3 Reliability and Factor Analysis Oblimin rotation factor analysis was conducted to assess the uni-dimensionality and discriminant validity of the instruments in TRA model and purchase intention by using fixed number of factors to extract. Problematic items were suppressed. The new factors were significant for KMO and Bartlett‟s test of adequacy with 0.749. The factors were then restructured as the following. Internal reliability tests were conducted for all variables and the Cronbach‟s Alpha for each construct is more than 0.6, which is considered as acceptable. 6 Proceedings of 23rd International Business Research Conference 18 - 20 November, 2013, Marriott Hotel, Melbourne, Australia, ISBN: 978-1-922069-36-8 FACTORS Attitude towards behaviour Subjective norm Personal norm Purchase intention NO.

Correlation analyses were conducted on purchase intention and each of the following variables: attitude towards the behaviour, subjective norm and personal norm. Multiple linear regressions analysis was conducted to assess the relationship between TRA and purchase intention. In addition, mediation analysis was conducted to test the mediating role of personal norm between subjective norm and purchase intention. 4.0 Results 4.1 Descriptive Statistics VARIABLES Attitude towards behaviour Subjective norm Personal norm Purchase intention MEAN 3.8743 STANDARD DEVIATION 0.60853 3.7575 3.6766 3.2470 0.74619 0.72825 0.57364 Table 4.1.1 Mean and standard deviation of variables All statements were measured with a 5-point Likert scale. Table 4.1 shows the mean of the variables and the result shows that all variables have a mean which is higher than neutral. This indicates that respondents‟ attitude towards behaviour, subjective norm and personal norm are positive and led them to have a high intention in socially responsible purchasing in the future. Besides that, the mean of subjective norm is slightly higher than personal norm. This indicates that consumer‟s feelings about altruistic behaviour are weaker than social pressure in socially responsible purchasing. However, both variables are still positive. Standard deviation of 0.5 to 0.7 for each variable indicates that degree of consistency among respondents is quite high. 7 Proceedings of 23rd International Business Research Conference 18 - 20 November, 2013, Marriott Hotel, Melbourne, Australia, ISBN: 978-1-922069-36-8 4.2 Correlation Analysis VARIABLES Attitude towards behaviour Subjective norm Personal norm Purchase intention Attitude towards behaviour 1 0.414 0.424 0.436 Subjective Personal norm norm Purchase intention 0.414 0.424 0.436 1 0.343 0.350 0.343 1 0.497 0.350 0.497 1 Table 4.2.1 Correlation among variables The correlations among variables are all significant . It indicates that H2, H3 and H4 were accepted that each variable, attitude towards behaviour (0.436), subjective norm (0.350) and personal norm (0.497) have a positive relationship with consumers‟ purchase intention. Personal norm has a highest correlation with purchase intention than others. However, correlation cannot test the causal relationship between independent variables and dependent variables. Therefore, multiple linear regression was carried out to test the casual relationship. 4.3 Multiple Regression Analysis Multiple linear regression analysis was used to gauge the relative importance of each variable in predicting purchase intention in socially responsible products. In this research, the dependent variable is purchase intention while attitude towards behaviour and subjective norm are independent variables. The assumptions of multiple linear regression analysis, which are linearity, multicollinearity, normality and homoscedastic, were all tested and passed. In order to get the best result, the influential cases were deleted based on values that are greater than Cook Distance , Leverage , Studendised residual | | or Mahalanobis Distance . Firstly, those influential cases were tested one by one to see whether the R square increases or decreases compared to the original model (R square = 0.096). The influential cases that lead the R Square to increase will be deleted from the model. In contrast, the influential cases that lead the R Square to decrease will be maintained in the model. Lastly, 11 influential cases were deleted and the model had developed by enter regression: Model 1 R Square 0.225 Model Summary Adjusted R Std.

In the TRA model, purchase intention was regressed on attitude towards behaviour and subjective norm. The result explained 22.5% of the variance in purchase intention of socially responsible products and supported hypothesis 1. Both variables in the model were proved to have a significant direct influence on purchase intention. For every 1 % increased in attitude towards behaviour, the purchase intention in socially responsible products will increase for 33.1%. For every 1% increased in subjective norm, purchase intention will increase for 15.7%. 4.4 Mediation Analysis 4.4.1 Subjective Norm, Personal Norm and Purchase Intention Subjective norm 0.35*** Purchase intention (0.204**) Diagram 4.4.1 Mediation of personal norm 0.343*** 0.497*** (0.427***) Personal Norm Diagram 4.4.1 Mediation of personal norm Diagram 4.4.1 shows the beta weight of subjective norm on purchase intention had dropped from 0.35 to 0.204 after the inclusion of personal norm. Baron and Kenny (1986) stated that there will be a significant mediation for the relationship if there is a significant drop in beta after a variable is added. The result shows that personal norm has a significant mediating effect on the relationship and then tested with Sobel‟s test. The test indicated that personal norm has a significant partial mediating effect on the relationship with a ratio of 0.7157 and z-value of 3.727229 (p<0.001). Therefore, hypothesis 6 was accepted. 9 Proceedings of 23rd International Business Research Conference 18 - 20 November, 2013, Marriott Hotel, Melbourne, Australia, ISBN: 978-1-922069-36-8 5.0 Discussion and Implication 5.1 Discussion The main objective of this research is to find out if the theory of reasoned action which comprises attitude towards behaviour and subjective norm could facilitate the prediction of socially responsible purchasing in Malaysia. The results of this study showed that the model of TRA was statistically significant to explain 22.5 percent of variance in consumer‟s intention in socially responsible purchasing. This is in line with a study that both attitude towards behaviour and subjective norm will positively affect loan applications (Ryan and Bonfield, 1980). Therefore, the TRA is a valid model of prediction. Consistent to the study by Gwendolyn and Marsha (2008), this research found that attitude is positively and significantly related to purchase intention (β= 0.331). The findings also showed that subjective norm positively and significantly predicted purchase intention (β=0.157). This further confirmed the study by Suddin Lada et al. (2009). In the multiple linear regression model, attitude towards behaviour has a higher ability to predict purchase intention (β= 0.331) than subjective norm (β=0.157). The results are consistent with prior researches which found that attitude has a higher predictive value than subjective norm (Thompson and Thompson, 1996; Syed Shah Alam and Nazura Mohamed Sayuti, 2011). From the research, it is also found that personal norm which is not included in the TRA, has the highest correlation of 0.497 with the purchase intention among the three predictors. The result concluded that besides attitude and subjective norm, personal norm can also positively predict purchase intention. In addition, the research found that personal norm has a significantly partial mediating effect on subjective norm and purchase intention with a ratio of 0.7157. The finding is in line with the study by Taute and McQuitty (2004). Lastly, this research found that personal norm also partially mediated attitude and purchase intention with a ratio of 0.5855. 5.2 Implications The attitude towards behaviour appeared to most effectively predict purchase intention of socially responsible products in Malaysia. In order to encourage socially responsible purchasing, companies in Malaysia should focus on public activities such as designing awareness campaigns to influence consumers‟ beliefs and attitudes regarding socially responsible purchasing. As subjective norm is also a predictor of purchase intention, the government and companies should focus on creating social expectations regarding socially responsible purchasing. It is also recommended for socially responsible companies to focus on promoting their CSR activities such as a better CSR disclosure In addition, the government may consider giving education regarding socially responsible purchasing to improve consumers‟ personal moral beliefs as they may act differently if they have more knowledge regarding this issue. 10 Proceedings of 23rd International Business Research Conference 18 - 20 November, 2013, Marriott Hotel, Melbourne, Australia, ISBN: 978-1-922069-36-8 6.0 Conclusion, Limitations and Future Research In conclusion, this research shows that the theory of reasoned action provides a useful conceptual framework in predicting the purchase intention of socially responsible products. Attitude towards the behaviour and subjective norms are found to predict purchase intention in socially responsible products. The findings were matching the objectives in this research. Although there are plenty of evidences for the relationship between attitude towards the behaviour, subjective norms and purchase intention, the model still cannot accurately predict behavioural intention. Therefore, an extra independence variable, personal norm was incorporated into this research and the results showed that personal norm did improve the prediction. Hence, the extended model provides a better understanding in socially responsible purchasing from psychosocial perspectives. This research identifies a few constraints that can be looked into in future research. Firstly, this research is done with the majority of respondents being in the age group of 20 to 30 years. Regarding the limitation, future research might consider to identify respondents with more different age groups. Secondly, the research is restrictive as the survey distribution is limited to a small suburban area, that is, Bandar Sunway. Hence, the results may or may not be suitable in other places. Therefore, collecting data from respondents in different areas is encouraged for future research. Thirdly, the model of this research is made up from three identified determinants such as attitude toward the behaviour, subjective norms and personal norm. Future research might consider incorporating more possible determinants such as respondent‟s motivation to purchase and other psychological factors. Furthermore, quantitative method (questionnaires) was used in this research. Qualitative research method such as interviews and secondary data could be used in future research. References Ajzen, I.
