一项基于表现的同伴影响敏感性测量作为同伴规范与青少年性交伴侣数量轨迹之间纵向关联的调节因素进行了研究。71名九年级青少年（52%为女性）参与了一项实验“聊天室”范式，其中包括支持性风险行为的“e联盟”。参与者在“聊天室”之前和期间对风险情景的反应变化被用作基于表现的同伴影响敏感性衡量标准。参与者在基线时报告了他们对受欢迎的同龄人的性伴侣数量的看法，并在基线和6个月、12个月和18个月后报告了他们的性伴侣数量。在受欢迎的同龄人的性伴侣数量和青少年自己的性伴侣数量的轨迹之间的纵向关联中，易感性被检验为调节因素。对受欢迎的同龄人的性伴侣数量的高感知，加上对同伴影响的高敏感性，预示着青少年的性伴侣数量的纵向轨迹更陡峭。研究结果为同伴影响易感性在青少年性行为发展中的重要性提供了新的初步证据。
A performance-based measure of peer influence susceptibility was examined as a moderator of the longitudinal association between peer norms and trajectories of adolescents' number of sexual intercourse partners. Seventy-one 9th grade adolescents (52% female) participated in an experimental "chat room" paradigm involving "e-confederates" who endorsed sexual risk behaviors. Changes in participants' responses to risk scenarios before versus during the "chat room" were used as a performance-based measure of peer influence susceptibility. Participants reported their perceptions of popular peers' number of sexual intercourse partners at baseline and self-reported their number of sexual intercourse partners at baseline and 6, 12, and 18 months later. Susceptibility was examined as a moderator of the longitudinal association between perceptions of popular peers' number of sexual intercourse partners and trajectories of adolescents' own numbers of partners. High perceptions of the number of popular peers' sexual intercourse partners combined with high peer influence susceptibility predicted steeper longitudinal trajectories of adolescents' number of partners. Results provide novel preliminary evidence regarding the importance of peer influence susceptibility in adolescents' development of sexual behaviors.
