Guided by narrative engagement theory and social cognitive theory, the present study investigates effects of narrative persuasion and peer communication on Nicaraguan adolescent substance use. Eighth-grade students in Nicaragua were recruited to participate in the culturally grounded, school-based prevention intervention Dale se REAL and to watch five entertainment-education intervention videos that teach drug refusal communication strategies. Using the cross-sectional survey (N = 224), a path analysis was run to examine the mediated moderation effects of narrative engagement (e.g., interest, realism, and identification with main characters) and peer communication about the intervention videos (e.g., frequency and valence of communication) on adolescent refusal self-efficacy and substance use behaviors. Results revealed that realism was significantly related to adolescent refusal self-efficacy and frequent peer communication moderated the association between refusal self-efficacy and the past 30-day marijuana use. Findings suggest that health communication scholars should take into consideration social factors and cultural contexts for adolescent substance use prevention research.

本研究以叙事参与理论和社会认知理论为指导，探讨叙事说服和同伴交流对尼加拉瓜青少年物质使用的影响。尼加拉瓜的八年级学生被招募参加以文化为基础、以学校为基础的预防干预Dale se REAL，并观看五个教授拒绝药物沟通策略的娱乐教育干预视频。使用横断面调查（N= 224），进行了路径分析，以检查叙事参与（例如，兴趣、现实主义和对主角的认同）和关于干预视频的同伴交流（例如，交流的频率和效价）对青少年拒绝的中介调节作用自我效能感和物质使用行为。结果表明，现实主义与青少年拒绝自我效能感显着相关，频繁的同伴交流调节了拒绝自我效能感与过去 30 天大麻使用之间的关联。研究结果表明，健康传播学者应考虑青少年物质使用预防研究的社会因素和文化背景。
