Three randomized experiments tested and attempted to replicate a serial multiple mediator model where a performer’s intimate self-disclosure positively affected viewers’ message acceptance via increased perceptions of performer authenticity and feelings of interpersonal liking. In Study 1 (n = 415), participants were randomly assigned to watch a short video where the performer, a male college student, either engaged in self-disclosure or did not while presenting a prosocial, mental health-related message. Throughout both versions of the video (self-disclosure, no-disclosure), the performer gazed and spoke directly into the camera and addressed the viewer’s presence, thereby engaging in parasocial interaction. Study 2 (n = 520) was close conceptual replication of Study 1 that featured a different performer (female college student) in the video stimuli. Findings replicated that of Study 1, where the performer’s intimate self-disclosure increased people’s message acceptance via people’s perceived authenticity and liking of the performer. Study 3 attempted to further replicate and extend the first two studies by featuring a third different performer and a different persuasive message in video stimuli. Findings partially replicated Studies 1 and 2, and the implications of these findings are discussed.
