How and when social media influencers' intimate self-disclosure fosters purchase intentions: the roles of congruency and parasocial relationships

PurposeThis study aims to explore the impact of social media influencers' (SMIs) intimate self-disclosure on consumers' purchase intentions, with a focus on the role of parasocial relationships and congruence among the influencer, product and consumer. The study finds its theoretical foundation in parasocial theory and self-congruency theory.Design/methodology/approachThis study employs a quantitative approach, utilizing a sample of 232 collected survey responses. The proposed hypotheses are evaluated using partial least squares structural equation modeling (PLS-SEM).FindingsContrary to initial assumptions, the study reveals that parasocial relationships do not mediate the link between SMIs' intimate self-disclosure and purchase intentions. However, an interesting moderating effect was discovered: the congruence between the consumer and the influencer influences the relationship between SMIs' intimate self-disclosure and parasocial relationships, and subsequently, between parasocial relationships and purchase intentions.Originality/valueThis study brings fresh insights by pinpointing a boundary condition that dictates the influence of SMIs' intimate self-disclosure on purchase intentions via parasocial relationships. In doing so, this study provides a novel perspective in understanding the dynamics between SMIs and consumers in the rapidly evolving marketing landscape.
