The Psychology Behind Influencer Identification and Brand Adoption: An Integrated Consumer Behavior Perspective

Abstract

The rapid expansion of social media platforms has transformed traditional brand communication into an influencer-driven ecosystem. Consumers increasingly rely on digital influencers for product discovery, evaluation, and purchase decisions. This study explores the psychological mechanisms underlying influencer identification and its effect on brand adoption. Drawing upon Social Identity Theory, Parasocial Interaction Theory, and the Source Credibility Model, the research proposes an integrated framework explaining how perceived similarity, authenticity, attractiveness, trustworthiness, and expertise drive influencer identification, leading to increased brand adoption. A quantitative survey of 468 social media users was conducted, and Structural Equation Modeling (SEM) was applied for hypothesis testing. The results reveal that authenticity, trustworthiness, and perceived similarity are the strongest predictors of influencer identification, while identification significantly enhances brand attitude and purchase intention. The study contributes to digital marketing psychology by offering a comprehensive explanation of how psychological attachment to influencers translates into measurable brand adoption outcomes.
