Both parasympathetic nervous system regulation and receipt of social support from close relationships contribute to prosocial development, although few studies have examined their combined influences in adolescence and particularly within racially and ethnically minoritized populations. In this longitudinal study of 229 U.S. Mexican-origin adolescents (48% female-identifying), youths reported on receipt of social support from family and friends from 10 to 16 years, had their baseline respiratory sinus arrhythmia (RSA) measured at 17 years, reported their prosocial behavior and completed the Mind in the Eyes test to assess cognitive empathy at 17 and 19 years, and reported their prosocial civic behavior (i.e., community activity) at 19 years. Family social support predicted prosocial behavior at 17 years, and friend social support predicted prosocial civic behavior at 19 years. Compared to youths with lower or higher baseline RSA, youths with moderate RSA reported more prosocial civic behavior, had greater cognitive empathy, and tended to report more general prosocial behavior at 19 years. The quadratic association between baseline RSA and cognitive empathy was stronger for youths with greater family social support. These findings are the first to extend the evidence that moderate baseline parasympathetic nervous system activity supports prosocial development into late adolescence and with the U.S. Mexican-origin community, and these findings address calls for more integrative biopsychosocial studies of prosociality.

副交感神经系统的调节和来自亲密关系的社会支持都有助于亲社会的发展，尽管很少有研究在青少年时期，尤其是在种族和民族少数群体中，同时考察它们的综合影响。在这项对 229 名美国墨西哥裔青少年（48%为女性）的纵向研究中，青少年从 10 岁到 16 岁期间报告了从家庭和朋友那里获得的社会支持情况，在 17 岁时测量了他们的基础呼吸窦性心律失常（RSA），在 17 岁和 19 岁时报告了他们的亲社会行为，并完成了“Mind in the Eyes”测试以评估认知同理心，在 19 岁时报告了他们的亲社会公民行为（即社区活动）。家庭社会支持预测了 17 岁时的亲社会行为，而朋友社会支持则预测了 19 岁时的亲社会公民行为。与基线 RSA 较低或较高的青少年相比，基线 RSA 中等的青少年报告了更多的亲社会公民行为，具有更强的认知同理心，并且在 19 岁时更倾向于报告更多的一般亲社会行为。基线 RSA 和认知同理心之间的二次关联在家庭社会支持较高的青少年中更为强烈。这些发现首次将中等水平的基础副交感神经系统活动支持亲社会发展的证据扩展到了青少年晚期，并扩展到了美国墨西哥裔社区，这些发现满足了人们对亲社会性进行更多综合生物心理社会研究的呼吁。（PsycInfo 数据库记录（c）2024 APA，保留所有权利）。
