The present study examined whether skin conductance level reactivity (SCLR) moderated prospective associations linking peer victimization with externalizing behaviors and depressive symptoms across the transition to middle school. Participants included 123 early adolescents (M age = 12.03 years at T1; 50% male; 58.5% European Americans, 35% African Americans, 6.5% of other races/ethnicities). At Time 1, SCLR was measured in the context of peer-evaluative challenges, and early adolescents and teachers reported on peer victimization. At Time 1 and Time 2, early adolescents and parents reported on depressive symptoms and externalizing behaviors, respectively. SCLR moderated prospective associations between peer victimization and depressive symptoms, such that both adolescent- and teacher-reported peer victimization predicted higher Time 2 depressive symptoms more strongly at lower levels of SCLR compared to higher levels of SCLR. SCLR did not moderate the prospective association between peer victimization and externalizing behaviors. Results of the present study suggest that low reactivity in the inhibitory dimension of the sympathetic nervous system may increase vulnerability to depressive symptoms in the context of peer victimization, whereas higher reactivity may operate as a protective factor.
本研究考察了皮肤电传导水平反应（SCLR）是否调节了同伴侵害与进入中学后外化行为和抑郁症状之间的前瞻性关联。参与者包括 123 名早期青少年（T1 时的平均年龄为 12.03 岁；50%为男性；58.5%为欧洲裔美国人，35%为非裔美国人，6.5%为其他种族/族裔）。在同伴评价挑战的背景下测量了 SCLR，早期青少年和教师报告了同伴侵害情况。在 T1 和 T2 时，早期青少年和父母分别报告了抑郁症状和外化行为。SCLR 调节了同伴侵害与抑郁症状之间的前瞻性关联，即与 SCLR 较高的水平相比，SCLR 较低的水平下，青少年和教师报告的同伴侵害更能预测更高的 T2 抑郁症状。SCLR 并没有调节同伴侵害与外化行为之间的前瞻性关联。本研究的结果表明，抑制性交感神经系统的低反应性可能会增加在同伴侵害的背景下对抑郁症状的易感性，而较高的反应性可能是一种保护因素。
