This study investigates bidirectional associations between adolescents' daily experiences of victimization and aggression perpetration within friendships. We investigated (a) across-day associations between victimization and aggression perpetration; (b) morning cortisol activity as a moderator of cross-day victimization and aggression links; and (c) potential sex differences in these patterns. For 4 consecutive days, 99 adolescents (M = 18.06, SD = 1.09, 46 females) reported whether they were victimized by or aggressive toward their friends. On three of these days, adolescents provided three morning saliva samples. Multilevel path analyses showed that across days, victimization and aggression were bidirectionally linked, but only for male adolescents. Additionally, for male adolescents, morning cortisol output (but not morning cortisol increase) moderated the association between victimization and next-day aggression; victimization predicted greater next-day aggression for boys with low, but not high, morning cortisol output. Findings implicate a physiological factor that may modify daily links between victimization and aggression in male adolescent friendships.
本研究调查了青少年在友谊中每天遭受侵害和实施攻击行为之间的双向关联。我们调查了：（a）侵害和攻击行为之间的跨日关联；（b）晨皮质醇活动作为跨日侵害和攻击联系的调节因素；以及（c）这些模式中的潜在性别差异。在连续 4 天里，99 名青少年（M=18.06，SD=1.09，46 名女性）报告了他们是否被朋友侵害或对朋友有攻击性。在其中三天，青少年提供了三份早晨唾液样本。多层次路径分析表明，在不同的日子里，侵害和攻击是双向关联的，但仅适用于男性青少年。此外，对于男性青少年，晨皮质醇输出（而不是晨皮质醇增加）调节了侵害与次日攻击之间的关联；对于晨皮质醇输出较低而非较高的男孩，侵害预示着次日攻击性更强。这些发现暗示了一种生理因素，可能会改变男性青少年友谊中侵害和攻击之间的日常联系。
