目的:探究反刍思维在大学生社交焦虑与手机成瘾倾向间的中介作用。方法:使用社交回避及苦恼量表(social avoidance and distress scale，SAD)、手机成瘾倾向量表(mobile phone addiction tendency scale，MPATS)和反刍思维量表(ruminative response scale，RRS)对682名大学生进行测量。采用SPSS 25.0及Mplus 7.0进行数据分析，用Pearson相关分析考察社交焦虑、手机成瘾倾向、反刍思维的相关性，用Bootstrap法检验反刍思维在大学生社交焦虑与手机成瘾倾向间的中介作用。结果:大学生社交焦虑总分为(13.36±6.02)分，反刍思维总分为(51.04±11.56)分，手机成瘾倾向总分(40.46±11.74)分。大学生手机成瘾倾向检出率为23.90%，社交焦虑检出率为49.85%。大学生社交焦虑总分与反刍思维总分呈正相关(n r＝0.31，n P<0.01)，与手机成瘾倾向总分呈正相关(n r＝0.25，n P<0.01)，大学生反刍思维总分与手机成瘾倾向总分呈正相关(n r＝0.46，n P<0.01)。结构方程模型显示，反刍思维在高社交焦虑和手机成瘾倾向间起到完全中介作用，效应值为0.18；低社交焦虑与大学生手机成瘾倾向间不存在中介效应，直接效应为0.33。n 结论:低社交焦虑直接影响大学生手机成瘾倾向，高社交焦虑通过反刍思维间接对手机成瘾倾向产生影响。“,”Objective:To explore the mediating effect of rumination between social anxiety and mobile phone addiction tendency among college students.Methods:The social avoidance and distress scale (SAD), mobile phone addiction tendency scale (MPATS) and ruminative response scale (RRS) were used to measure 682 college students.SPSS 25.0 and Mplus 7.0 were used for data analysis.Pearson correlation analysis was used to explore the correlation among social anxiety, mobile phone addiction tendency and rumination.Bootstrap method was used to test the mediating effect of rumination between social anxiety and mobile phone addiction tendency among college students.Results:The total score of social anxiety was (13.36±6.02), the total score of rumination was (51.04±11.56), and the total score of mobile phone addiction tendency was (40.46±11.74). The detection rate of mobile phone addiction tendency was 23.90%, and the detection rate of social anxiety was 49.85%.The total score of social anxiety was positively correlated with the total score of rumination (n r=0.31, n P<0.01) and the total score of mobile phone addiction tendency (n r=0.25, n P<0.01). The total score of rumination was positively correlated with the total score of mobile phone addiction tendency (n r=0.46, n P<0.01). The structural equation model showed that rumination played a complete mediating role between high social anxiety and mobile phone addiction tendency, and the effect value was 0.18.There was no mediating effect between low social anxiety and mobile phone addiction tendency, and the direct effect value was 0.33.n Conclusion:Low social anxiety directly affects college students' tendency of mobile phone addiction, while high social anxiety indirectly affects college students' tendency of mobile phone addiction through rumination.
