【摘要】 目的·基于问题行为理论，构建结构方程模型，开展对于大学生社交网络成瘾的相关研究。方法·在上海市某高校一、二年级本科生中开展关于大学生社交网络成瘾的横断面问卷调查，采用Logistic回归分析性别、年级、学习压力、自尊、孤独感、抑郁、困顿感、挫败感、人际需求、社会支持、吸烟、饮酒、运动和学习成绩对社交网络成瘾的影响。以问题行为理论为理论框架，构建大学生社交网络成瘾的理论框架模型。结果·60.31%(591/980)的低年级大学生有社交网络成瘾情况。单因素Logistic回归结果显示：抑郁、自尊、孤独感、挫败感、困顿感、社会支持、人际需求、运动和学习成绩对社交网络成瘾有显著影响。研究构建的大学生社交网络成瘾的结构方程模型拟合结果良好[S-Bχ2/df=8.03，拟合指数（goodness-of-fit index,GFI）=0.924，比较拟合指数（comparative fit index,CFI）=0.909，非规范拟合指数（TuckerLewis index,TLI）=0.872，近似误差均方根（root mean square error of approximation,RMSEA）=0.096，标准化残差均方根（standardized root mean square residual,SRMR）=0.070]，提示人格系统与社会环境系统之间、人格系统与行为系统之间、社会环境系统与行为系统之间均相互影响（β=1.018,P=0.000;β=0.218,P=0.003;β=0.268,P=0.000）。人格系统和行为系统对社交网络成瘾的影响在统计学上不存在显著性，社会环境系统对社交网络成瘾有显著的正向影响（β=0.481,P=0.001）。结论·人格系统和行为系统通过影响社会环境系统间接影响社交网络成瘾，社会环境系统直接影响社交网络成瘾。对于低年级大学生社交网络成瘾问题，应当充分尊重大学生的特点，从系统3个层面共同入手，降低大学生社交网络成瘾风险。更多还原

【Abstract】 Objective·To construct a structural equation model based on problem behavior theory to conduct a study on social network addiction among junior college students. Methods·A cross-sectional questionnaire survey was conducted in a college in Shanghai. Logistic regression analysis was used to analyze the effects of gender, grade, study pressure, self-esteem, loneliness,depression, entrapment, defeat, interpersonal needs, perceived social support, smoking, alcohol, exercise, and academic achievement on social network service addiction. Based on the problem behavior theory, the structural equation model was used to construct a theoretical framework model of social network service addiction of junior college students. Results·60.31% of the total 980participants had social network service addiction. The univariate Logistic regression results showed that depression, self-esteem,loneliness, frustration, drowsiness, social support, interpersonal needs, exercise, and academic performance had a significant impact on social network addiction. The structural equation model fitted well [S-Bχ2/df=8.03, goodness-of-fit index(GFI) =0.924,comparative fit index(CFI) =0.909, Tucker-Lewis index(TLI) =0.872, root mean square error of approximation(RMSEA) =0.096,standardized root mean square residual(SRMR) =0.070], suggesting the mutual influence between the personality system and the perceived environment system, between the personality system and the behavioral system, and between the perceived environment system and the behavior system interact(β =1.018, P=0.000; β =0.218, P=0.003; β =0.268, P=0.000). The influence of personality system and behavior system on social network service addiction was not statistically significant, while the perceived environment system had a significant positive impact on social network service addiction(β=0.481, P=0.001). Conclusion·Personality system and behavior system indirectly affect social network service addiction by influencing perceived environment system, and perceived environment system directly affects social network service addiction. For the problem of social network addiction among lower grade college students, it is necessary to fully respect the characteristics of college students, and work together from three levels of the system to reduce the risk of social network addiction among college students.更多还原
