This study investigates the psychological mechanism by which source interactivity influences health message evaluations. Combining health communication and interactivity literature, two theoretical routes to persuasion were proposed: enhanced sense of community and reduced psychological reactance. A 2 × 2 (source interactivity: absence vs. presence X smoking status: nonsmoker vs. current smoker) factorial-design experiment ( = 343) was conducted on an anti-smoking website. Result revealed that the endorsing and sharing features that resembled the Like button on Facebook enhanced self-as-source perceptions and sense of community, which exerted significant effects on message credibility for smokers and message enjoyment for nonsmokers. Among smokers, self-as-source perceptions reduced psychological reactance, which promoted greater message credibility and more negative attitudes toward smoking behavior.
本研究旨在探讨来源互动影响健康信息评估的心理机制。本研究结合健康传播和互动性文献，提出了两种说服的理论途径：增强的社区感和减少的心理抗拒。在一个反吸烟网站上进行了一项 2×2（来源互动：缺席与存在×吸烟状况：非吸烟者与当前吸烟者）的因子设计实验（n=343）。结果表明，类似于 Facebook 上的“赞”按钮的点赞和分享功能增强了自我作为信息源的认知和社区感，这对吸烟者的信息可信度和非吸烟者的信息享受产生了显著影响。在吸烟者中，自我作为信息源的认知减少了心理抗拒，从而提高了信息可信度和对吸烟行为的更负面态度。
