Social commentary about prevention messages may affect their likelihood of acceptance. To investigate this possibility, student participants (N = 663) viewed 3 antimarijuana advertisements, each followed immediately by videotaped discussions involving 4 adults or 4 adolescents using either extreme or moderate language in their positive commentaries. The commentaries were expected to affect participants' perceptions of the extent to which the ads were designed to control their behavior (perceived control), which was hypothesized to inhibit persuasion. Two indirect effects analyses were conducted. Marijuana attitudes and usage intentions were the outcome variables. Both analyses revealed statistically significant source by language interactions on participants' perceived control (both p < .02). Further analyses revealed significant indirect effects of language extremity on attitudes and intentions through perceived control with adult, but not peer sources (both p < .05). These perceptions were associated with more negative marijuana attitudes and diminished usage intentions when adults used moderate (vs. extreme) language in their favorable ad commentaries (both p < .05). The findings may facilitate development of more effective prevention methods that emphasize the importance of the role of perceived control in persuasion, and the impact of interpersonal communication variations on acceptance of media-transmitted prevention messages.

关于预防信息的社会评论可能会影响其被接受的可能性。为了探究这种可能性，学生参与者（N = 663）观看了3则反大麻广告，每则广告之后紧接着是录像讨论，讨论中4名成年人或4名青少年在积极评论中使用了极端或温和的语言。这些评论预计会影响参与者对广告旨在控制他们行为程度的认知（感知控制），而这被假设会抑制说服力。进行了两项间接效应分析。大麻态度和使用意图是结果变量。两项分析均显示，语言与信息源的交互作用对参与者的感知控制具有统计学意义（均p < .02）。进一步分析表明，语言极端程度通过成人（而非同龄人）信息源的感知控制对态度和意图产生显著的间接效应（均p < .05）。当成年人在对广告的正面评论中使用温和（而非极端）语言时，这些认知与更负面的大麻态度和降低的使用意图相关（均p < .05）。这些发现可能有助于开发更有效的预防方法，强调感知控制在说服过程中的作用的重要性，以及人际沟通差异对媒体传播的预防信息接受度的影响。（PsycINFO数据库记录）
