大学生核心自我评价对手机依赖的影响：述情障碍与焦虑的链式中介作用

The Influence of College Students’ Core Self-Evaluation on Mobile Phone Dependence: The Chain Mediating Effect of Alexithymia and Anxiety

摘要: 目的：探究述情障碍和焦虑因子在大学生核心自我评价与手机依赖之间的作用。方法：采用手机依赖量表(MPATS)、核心自我评价量表(CSES)、SCL-90焦虑分量表及多伦多述情障碍量表(TAS)对700名大学生进行问卷调查。结果：① 核心自我评价得分分别与述情障碍得分、焦虑得分以及手机依赖得分呈显著负相关；述情障碍得分分别与焦虑得分、手机成瘾得分呈显著正相关；焦虑得分与手机成瘾得分呈显著正相关。② 述情障碍在核心自我评价与手机依赖之间起中介作用，中介效应比率为27.02%。③ 焦虑在核心自我评价与手机依赖之间起中介作用，中介效应比率为8.63%。④ 述情障碍与焦虑在核心自我评价与手机依赖之间起链式中介作用，中介效应比率为5.15%。结论：述情障碍和焦虑因子是核心自我评价与手机依赖之间的中介因素，并具有链式中介效应。

Abstract: Objective: To explore the role of alexithymia and anxiety factors in college students’ core self- evaluation and mobile phone dependence. Method: 700 college students were investigated by Mobile Phone Dependence Scale (MPATS), Core Self-Evaluation Scale (CSES), SCL-90 Anxiety Subscale and Toronto Alexithymia Scale (TAS). Result: ① The core self-evaluation score was significantly negatively correlated with alexithymia score, anxiety score and mobile phone dependence score; alexithymia score was positively correlated with anxiety score and mobile phone addiction score respectively; there was a significant positive correlation between anxiety score and mobile phone addiction score. ② Alexithymia played a mediating role in core self-evaluation and mobile phone dependence, and the mediating effect ratio was 27.02%. ③ Anxiety played a mediating role in core self-evaluation and mobile phone dependence, and the mediating effect ratio was 8.63%. ④ Alexithymia and anxiety played a chain mediating role in core self-evaluation and mobile phone dependence, and the mediating effect ratio was 5.15%. Conclusion: Alexithymia and anxiety factors are mediating factors between core self-evaluation and mobile phone dependence, and they have a chain mediating effect.
