The aim of this study is to determine the effect of the self-expression and the need of social affiliation factors on the brand attitude, positive electronic word of mouth marketing (positive E-WOM) behavior and purchasing intention of consumers in the X, Y and Z generations. With the determination of how sports celebrities can be used effectively in social media ads, businesses will be able to benefit more effectively from social media ads using sports celebrities. Sports Celebrities’ encouragement to their followers for self-expression and meeting their needs of social affiliation on social media pages can be important factors to influence consumer perception positively. The data survey was obtained from the questionnaire forms done with 608 participants from generations X, Y, Z by using convenience sampling method in January-April of the year 2019. Structural equation model was used for the analysis of the data obtained from 608 participants. As a result of the study, the self-expression factor influences only the positive E-WOM behaviour for generation X. The need of social affiliation has no effect on any of these generations. In terms of generations Y and Z, self-expression factor has an effect on brand attitude and positive E-WOM behaviour. The need of social affiliation factor has effect on brand attitude, positive E-WOM behaviour and purchasing intention for generation Y. On the other hand the need of social affiliation factor has a direct effect on purchasing intention for generation Z. Thus, sports celebrities should give opportunities to generations Y and Z to express their feelings and thoughts comfortably on their personal and fan pages on social media and developing friendly relations with their followers on social media, which will enable them to make more effective advertisements.
