INTRODUCTION Self-control predicts academic achievement and social outcomes in adolescents. Despite the increased role of peers in the lives of adolescents, little is known about whether peers' views of an individual's self-control have predictive validity for academic and social outcomes. METHOD In a longitudinal study involving over 1500 adolescents (Mage  = 13.74), we examined whether peer nomination of self-control provides incremental predictive validity over and above self-reports for rank-order changes in academic achievement and friendship (i.e., the total number of nominations received as a best friend). To do so, we followed 8th graders through the 9th grade, measuring self-reported self-control (academic vs. social), peer-nominated self-control (academic vs. social), grade point average, and friendship. RESULTS Peer-nominated academic self-control predicted rank-order changes in grade point average and peer-nominated interpersonal self-control predicted rank-order changes in friendship over and above self-reported academic and interpersonal self-control. CONCLUSION Our findings demonstrate the predictive utility of peer nominations in research on self-control.

朋友认识你：自我控制的同伴提名预测青少年之间学业成就和友谊的变化。

引言 自我控制可以预测青少年的学业成就和社会成果。尽管同龄人在青少年生活中的作用越来越大，但人们对同龄人对个人自我控制的看法是否对学业和社会成果具有预测有效性知之甚少。方法 在一项涉及 1500 多名青少年 (Mage = 13.74) 的纵向研究中，我们检查了自我控制的同伴提名是否为学业成就和友谊的等级变化提供了超越自我报告的增量预测效度（即总数作为最好的朋友获得的提名）。为此，我们跟踪 8 年级学生到 9 年级，测量自我报告的自我控制（学术与社交）、同伴提名的自我控制（学术与社交）、平均成绩和友谊。结果 同伴提名的学术自我控制预测了平均成绩的排名变化，同伴提名的人际自我控制预测了友谊的排名变化，超过了自我报告的学术和人际自我控制。结论 我们的研究结果证明了同行提名在自我控制研究中的预测效用。
