英文摘要：

Prior researches revealed the positive relation between cyber-victimization and depression among adolescents. However, it was less known about the mechanisms underlying the relation between eyber-victimization and depression. Based on the buffering effect model of social support, this study examined a moderated mediation model which integrated the mediating effect of perceived stress and the moderating effect of online social support between cyber-vietimization and perceived stress, as well as between perceived stress and depression. A sample of 751 junior high school students completed the E-Victimization Scale, Perceived Stress Scale, Online Social Support Questionnaire and the Center for Epidemiologie Studies Depression Scale. The results showed that： （ 1 ） Cyber- victimization was positively associated with adolescents＇ depression; （2） Perceived stress could fully mediate the relation between eyber-vietimization and depression; （3） Online social support moderated the association between perceived stress which aroused by eyber-victimization and depression. With online social support increasing, the negative effect of perceived stress on adolescents＇ depression reduced, and this result provided substantial evidence that the buffering effect model of social support was also applicable to online social support in the cyber space. Thus, both mediating and moderating effects existed in the association between cyber-victimization and depression among adolescents.
