【摘要】 目的：探讨核心自我评价、生活质量与中学生手机依赖的关系。方法：采取分层整群抽样的方法，于2020年6月在厦门市4所普通中学选取1 692名学生参与研究，采用青少年手机使用依赖自评问卷（self-rating questionnaire for adolescent problematic mobile phone use,SQAPMPU）、核心自我评价量表（core self-evaluations scale,CSES）、儿童少年生活质量量表（quality of life scale for children and adolescents,QLSCA）对其进行调查，采用SPSS 23.0对数据进行描述统计、相关分析、回归分析，并进行中介效应检验。结果：中学生的核心自我评价、生活质量与手机依赖行为均有显著负相关（r=-0.394,P<0.001;r=-0.454,P<0.001），中学生的核心自我评价与生活质量有显著正相关（r=0.709,P<0.001）；生活质量（β=-0.163,t=-11.362,P<0.001）和核心自我评价（β=-0.177,t=-4.630,P<0.001）均对中学生手机依赖有显著负向预测作用；中学生的生活质量在核心自我评价和手机依赖之间存在中介作用，Bootstrap95%置信区间为（-0.372,-0.236）。结论：核心自我评价、生活质量是中学生手机依赖行为的重要影响因素，核心自我评价通过生活质量间接影响中学生手机依赖行为。更多还原

【Abstract】 Objective: To explore the relationship between core self-evaluation, quality of life and problematic mobile phone use among middle school students. Methods: The method of stratified cluster sampling was adopted. In June 2020, 1 692students from 4 ordinary middle schools in Xiamen were given the self-rating questionnaire for adolescent problematic mobile phone use(SQAPMPU), the core self-evaluations scale(CSES) and the quality of life scale for children and adolescents(QLSCA) were used to investigate them, and SPSS 23.0 was used to carry out descriptive statistics, correlation analysis,Regression analysis was performed, and a mediation effect test was performed. Results: Middle school students’ core selfevaluation, quality of life and problematic mobile phone use were significantly negatively correlated(r=-0.394, P<0.001;r =-0.454, P <0.001). There was a significant positive correlation between middle school students’ core self-evaluation and quality of life(r = 0.709, P <0.001). Both quality of life(β =-0.163, t =-11.362, P <0.001) and core self-evaluation(β =-0.177,t =-4.630, P <0.001)significantly negatively predicted middle school students’ problematic mobile phone use. The quality of life of middle school students had a significant mediating effect between core self-evaluation and problematic mobile phone use, Bootstrap 95% confidence interval was(-0.372,-0.236). Conclusion: Core self-evaluation and quality of life are important influencing factors of middle school students’ problematic mobile phone use. Core self-evaluation can affect middle school students’ problematic mobile phone use through quality of life.更多还原
