【摘要】 目的 探讨大学生社会自我效能感对网络成瘾的影响，分析压力知觉的中介作用以及自尊是否在此中介过程中发挥调节作用。方法 采用社会自我效能感问卷、压力知觉量表、自尊量表、网络成瘾量表对881名大学生进行问卷调查。结果 (1)社会自我效能感可负向预测网络成瘾（β=-0.06,P<0.01），负向预测压力知觉（β=-0.11, P<0.01）；(2)压力知觉在社会自我效能感与大学生网络成瘾间起部分中介作用，中介效应值为0.12，占总效应量的67%；(3)社会自我效能感通过压力知觉影响网络成瘾的前半段路径受到自尊的调节（β=-0.79,P<0.01）。结论 社会自我效能感、自尊、压力知觉及网络成瘾之间构成了有调节的中介模型。社会自我效能感越低的大学生网络成瘾可能性越大，压力知觉是社会自我效能感与网络成瘾之间重要的心理机制，自尊能够缓冲社会自我效能感对网络成瘾及压力知觉的影响。更多还原

【Abstract】 Objective To explore the relationship between social-efficacy and college students’ internet addiction, and to investigate the mediating role of perceived stress and whether self-esteem plays a moderating role in this mediating process. Methods A total of 881 college students were investigated using the Chinese Socialefficacy Scale, the Chinese Version of the Perception of Stress Scale, the Self-Esteem Scale and the Revised internet Addiction Scale were used. Results(1) Social-efficacy significantly negatively predicted internet addiction(β=-0.06, P<0.01), and significantly negatively predicted perceived stress(β=-0.11, P<0.01).(2) Perceived stress played a partial mediating role between social-efficacy and internet addiction, with a mediation effect value of 0.12, which accounted for 67% of the total effect.(3) The first half pathway of social-efficacy on internet addiction through perceived stress was moderated by self-esteem(β=-0.79, P<0.01). Conclusion Social-efficacy, selfesteem, perceived stress, and internet addiction, constituted a moderated mediation model. The lower sense of socialefficacy, the higher possibility of college students’ internet addiction, perceived stress is an important psychological mechanism between social-efficacy and internet addiction, self-esteem can buffer the impact of social-efficacy on internet addiction and perceived stress.更多还原
