Introduction
Celebrities are actively capitalizing on their fame and credibility by launching their own brand extensions which are heavily promoted on Instagram. This situation is especially prevalent in Malaysia among many local Malay ‘celepreneurs’. While consumers’ constant involvement with a celebrity on Instagram is believed to result in the purchase of celebrity branded products, the central question of how a causal variable such as Instagram involvement has an effect on the outcome of purchase has been less explored in contemporary studies. The role of celebrity adulation and style conformity in the context of celebrity branding-cum-entrepreneurship deserves much attention given the strong influence celebrities exert on young consumers in this digital era of accessible information.
Research framework
Given the admiration that young consumers have towards the celebrities they follow on Instagram, celebrity worship, in both pathological and non-pathological form, is believed to be a crucial link between their involvement with the social media and their desire to imitate their favourite celebrity’s style. Eventually this paves the way for the purchase of celebrity brand products given that getting the products is an avenue for the young consumers to attain their celebrities’ style. Therefore in this study, four variables that mediate the relationship between Instagram involvement and purchase of celebrity branded products are examined: celebrity worship as manifested across three varying levels particularly entertainment-social (lowest form of worship); intense-personal (mid-level); borderline pathological (highest level); and style conformity.
Method
Data was collected from 226 Malaysian women of Malay ethnicity who are active Instagram users and fall under the technology-savvy Millennial segment using a self-administered questionnaire. This segment of consumers is technology savvy and has personalities and lifestyles (Gurau, 2012). They also tend to imitate their favourite celebrity in contrast to their male counterparts (Djafarova & Rushworth, 2017). Measures for the mediating variables were derived from McCutcheon et al.’s (2002) Celebrity Worship Scale and Park and Yang’s (2010) items on celebrity style conformity. A five-point scale (1=strongly disagree to 5=strongly agree) was utilized to capture the responses to the variables measured.
Analysis and results
Serial multiple mediation testing was applied on the data using variance-based structural equation modelling. The multiple mediation analysis showed that of all the three levels of celebrity worship which mediate the link between Instagram involvement and style conformity, only celebrity worship (entertainment-social) was found to be a significant mediator between Instagram involvement and style conformity (Indirect effect=0.127; t-value= 3.285, 95% Boot CI: LL=0.059, UL=0.216). In addition, the presence of a serial mediation was detected for the link between Instagram involvement-celebrity worship (entertainment-social)-style conformity-purchase of celebrity brand products (Indirect effect=0.04; t-value=2.954, 95% Boot CI: LL=0.02, UL=0.08).
Conclusion
The serial mediation testing in this study has demonstrated that celebrity worship and style conformity serve as the missing link between the involvement-purchase relationship. Furthermore, the multiple mediation testing has shown that only celebrity worship at the basic level functions as a mediator. The findings of this study imply that the use of Instagram is indeed a compelling marketing communication tool that fosters the purchase of celebrity brand extensions. Constant involvement in Instagram by following the celebrity, liking, reposting, commenting or hashtagging on the celebrity’s account builds a keen sense of devotion for the celebrity whereby the individual will constantly watch, read and learn about the celebrity. This then heightens the user’s desire to emulate the style of the celebrity which may well lead them to purchase the celebrity’s products in an effort to imitate the celebrity’s look and demeanour. strong desire for and high willingness to spend on branded products that match their
