Abstract
This empirical research investigated the structural relationships between social media influencer attributes, perceived friendship, psychological well-being, loyalty, and perceived social responsibility of influencers, focusing on the perspective of social media users. More specifically, this study conceptually identified social media influencer attributes such as language similarity, interest similarity, interaction frequency, and self-disclosure and examined the respective effects of each dimension on perceived friendship and psychological well-being, consequently resulting in loyalty toward social media influencers. The authors collected and analyzed data from 388 social media users in the United States via Amazon's Mechanical Turk with multivariate analyses to test the hypothesized associations among the variables in this study. The findings indicated that perceived friendship was significantly influenced by language similarity, interest similarity, and self-disclosure, but did not have a significant impact on psychological well-being. Additionally, perceived friendship significantly affected psychological well-being and loyalty, and psychological well-being significantly influenced loyalty. Lastly, social media influencers' social responsibility moderated the path from psychological well-being to loyalty. Based on these findings, this study proposes theoretical and managerial implications for the social media influencer marketing context.
