We evaluated whether the association between deviant peer affiliation and onset of substance use is conditional upon sex and sympathetic nervous system (SNS) reactivity as measured by pre-ejection period (PEP). Community-sampled adolescents ( = 251; = 15.78 years; 53% female; 66% White, 34% Black) participated in three waves. PEP reactivity was collected during a mirror star-tracer stress task. Alcohol, marijuana, tobacco, or any substance use, as well as binge drinking and sexual activity involving substance use were outcomes predicted by affiliation with deviant peers and two- and three-way interactions with sex and PEP reactivity. Probability of substance use increased over time, but this was amplified for adolescents with greater deviant peer affiliation in conjunction with blunted PEP reactivity. The same pattern of results was also found for prediction of binge drinking and sexual activity involving substance use. Findings are discussed in the context of biosocial models of adolescent substance use and health risk behaviors.
我们评估了在青春期个体使用物质的起始与偏差同伴关系之间的关联是否受到性别和交感神经系统（SNS）反应性（以射血前期（PEP）衡量）的影响。本研究的参与者为社区抽样的青少年（n=251；年龄=15.78 岁；53%为女性；66%为白人，34%为黑人），他们参与了三个波次的研究。在进行镜像星迹追踪应激任务时，我们收集了 PEP 反应性数据。使用物质（包括酒精、大麻、烟草或任何物质）、 binge drinking（即酗酒）和包含物质使用的性行为是由与偏差同伴的联系以及性别和 PEP 反应性的二项式和三项式交互作用预测的结果。物质使用的可能性随着时间的推移而增加，但对于具有更高偏差同伴关系且 PEP 反应性迟钝的青少年来说，这种可能性会加剧。同样的结果模式也适用于预测 binge drinking（酗酒）和包含物质使用的性行为。研究结果在青少年物质使用和健康风险行为的生物社会模型背景下进行了讨论。
