Abstract: Organizational research has uncovered that stress experience not only have negative aspects but also positive aspects on mental health, so we explored the effect of stressful life events on adolescent’s self-esteem in the similar frame. We hypothesized that stressful life events had a total positive effect on adolescent’s self-esteem, with positive effect through the mediating role of presence of meaning, negative effect through the mediating role of passive network using, and negative effect through the serial mediating role of passive network using and presence of meaning. 605 adolescents (304 males; M±SD=14.82±1.56) participated in the study. Using the Meaning of Life Questionnaire (MLQ), Adolescent Stressful Life Events Questionnaire (ASLEC), Passive Use of Social Network Use Scale (PUSNU) and Self-esteem Scale were used to survey adolescent students. The data was analyzed by SPSS 24.0 and Mplus7.4. The results showed that: (1) Stressful life events had a total positive effect on self-esteem (β=.20, p<.01). (2) Passive network using mediated the relationship between stressful life events and self-esteem (-.0254

摘要： 采用青少年生活事件量表、被动性社交网站使用量表、生命意义感量表以及自尊量表对605名青少年施测，旨在探讨压力性生活事件对自尊的效应以及被动性社交网站使用和人生意义感的中介作用。结果发现：被动性社交网站使用和拥有人生意义感在压力性生活事件与自尊之间起中介作用，压力性生活事件分别通过被动性社交网站使用、拥有人生意义感的中介作用和被动性社交网站使用与拥有人生意义感的序列中介作用对自尊产生效应。
