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.
In a longitudinal study involving over 1500 adolescents (M = 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.
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.
Our findings demonstrate the predictive utility of peer nominations in research on self-control.
自我控制能力可以预测青少年的学业成绩和社交成果。尽管同伴在青少年生活中的作用越来越大，但对于同伴对个体自我控制能力的看法是否对学业和社交成果具有预测效度，我们知之甚少。
在一项涉及 1500 多名青少年的纵向研究中（M=13.74），我们考察了同伴提名的自我控制能力是否比自我报告的自我控制能力更能预测学业成绩和友谊（即作为最好的朋友收到的提名总数）的等级变化。为此，我们跟踪了 8 年级学生到 9 年级，测量了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）、平均绩点和友谊。
同伴提名的学术自我控制能力可以预测平均绩点的等级变化，而同伴提名的人际自我控制能力可以预测友谊的等级变化，这超过了自我报告的学术和人际自我控制能力。
我们的发现证明了同伴提名在自我控制研究中的预测效用。
