Previous studies have shown that interpersonal communication, and particularly perceived conversational valence (i.e., the perceived negativity or positivity of conversations) about health topics, influences health determinants. On the basis of 43 dyads (N = 86) discussing the topic of alcohol consumption, this study is the first to show that whereas perceived and objective conversational valence are positively related, only perceived conversational valence is a significant predictor of binge drinking attitudes and intentions. Thus, subjective reality matters more than objective reality. Furthermore, only the perceived valence of the participants' own contributions-and not of their conversation partners--influences binge drinking intentions, indicating that self-persuasion is more influential than persuasion by others. Thus, conversations in which discussants themselves express negative opinions about unhealthy behaviors can enhance public health.
以往的研究表明，人际沟通，尤其是关于健康话题的感知对话效价（即对话中感知到的消极或积极程度）会影响健康决定因素。基于43对讨论饮酒话题的二人组（N = 86），本研究首次表明，虽然感知对话效价与客观对话效价呈正相关，但只有感知对话效价是暴饮暴食态度和意图的重要预测指标。因此，主观现实比客观现实更重要。此外，只有参与者自身贡献的感知效价——而非其对话伙伴的——会影响暴饮暴食意图，这表明自我说服比他人说服更具影响力。因此，讨论者自身对不健康行为表达负面意见的对话可以促进公众健康。
