Research on peer socialization rarely examines individual differences in adolescents’ susceptibility to peer influence, perhaps because few theories or methods have elucidated how susceptibility is operationalized. This study offers a new analogue measure of peer influence susceptibility in adolescence that is adapted from sociological theory. A preliminary examination of this new paradigm included the study of individual differences in susceptibility to peer influence, convergent validity correlates, and predictive validity by examining decision-making on the task as a moderator of the prospective association between friends’ and adolescents’ engagement in one form of real-world risk-taking. Participants included 714 adolescents (54% female; 46.1% White, 20.9% Black, 24.2% Hispanic/Latinx, 6.2% mixed race or other) aged 15–18 years (M = 16.1). Participants completed the Peer Analogue Susceptibility Task, peer nominations, and self-report measures at Time 1 and repeated an assessment of their own alcohol use 1 year later. Participants’ friends also reported their own alcohol use. Results indicated concurrent associations with peer influence susceptibility, rejection sensitivity, perceived importance of peer status, peer-nominated popularity, and self-reported resistance to peer influence. Furthermore, among adolescents demonstrating average and high levels of peer influence susceptibility on the task, greater perceived alcohol use among friends was associated with their own alcohol use 1 year later. Findings offer preliminary evidence for the convergent and predictive validity of a new approach to study peer influence susceptibility.

关于同伴社会化的研究很少考察青少年对同伴影响易感性的个体差异，这可能是因为很少有理论或方法阐明易感性是如何运作的。这项研究提供了一种新的模拟衡量青春期同伴影响易感性的方法，该方法改编自社会学理论。对这种新范式的初步检验包括研究对同伴影响易感性、聚合效度相关性和预测效度的个体差异，方法是检查任务决策作为朋友和青少年参与的预期关联的调节者现实世界的冒险形式。参与者包括 714 名 15-18 岁的青少年（54% 女性；46.1% 白人，20.9% 黑人，24.2% 西班牙裔/拉丁裔，6.2% 混血或其他人）（M = 16.1)。参与者在时间 1 完成了同行模拟易感性任务、同行提名和自我报告措施，并在 1 年后重复评估自己的酒精使用情况。参与者的朋友也报告了他们自己的酒精使用情况。结果表明，与同伴影响敏感性、拒绝敏感性、同伴地位的感知重要性、同伴提名的受欢迎程度和自我报告的对同伴影响的抵抗力存在关联。此外，在对任务表现出平均和高水平的同伴影响敏感性的青少年中，朋友之间更多的酒精使用与他们自己一年后的酒精使用有关。研究结果为研究同伴影响易感性的新方法的收敛性和预测有效性提供了初步证据。
