This longitudinal study examined peer contagion of depressive symptoms over an 18-month interval within a sample of 100 11th-grade adolescents. Three types of peer contagion moderators were examined, including characteristics of adolescents (social anxiety, global self-worth), friends (level of friends' peer-perceived popularity), and the relationship between them (friendship quality). Measures were collected using adolescents' and their friends' reports of depressive symptoms, adolescents' reports of social anxiety, global self-worth, friendship quality, and a sociometric assessment of peer-perceived popularity. Results indicated that among girls higher levels of social anxiety were associated with adolescents' greater susceptibility to peer contagion. Among boys, higher levels of friends' peer perceived popularity and lower levels of positive friendship quality each were associated with greater susceptibility to depressive symptom contagion.
这项纵向研究在100名十一年级青少年样本中，考察了18个月期间抑郁症状的同伴传染情况。研究考察了三种同伴传染调节因素，包括青少年的特征（社交焦虑、总体自我价值）、朋友的特征（朋友在同伴眼中的受欢迎程度）以及他们之间的关系（友谊质量）。通过青少年及其朋友对抑郁症状的报告、青少年对社交焦虑、总体自我价值、友谊质量的报告以及对同伴感知受欢迎程度的社会测量评估来收集数据。结果表明，在女孩中，较高水平的社交焦虑与青少年更容易受到同伴传染有关。在男孩中，较高水平的朋友在同伴眼中的受欢迎程度和较低水平的积极友谊质量，各自都与更容易受到抑郁症状传染有关。
