大学生焦虑在手机依赖与核心自我评价间的中介效应

Mediating effect of anxiety on relationship between core self-evaluation and mobile phone dependence in college students

目的:探究大学生的焦虑在核心自我评价与手机依赖关系之间的中介效应。方法:采用手机依赖量表(MPAI)、核心自我评价量表(CSES)及焦虑自评量表(SAS)对759例大学生集体施测。结果:本样本中手机依赖筛查阳性的比例是73.0%;手机依赖组的MPAI得分低于非手机依赖组,而SAS得分高于非手机依赖组(P<0.001);大学生CSES得分与MPAI得分呈负相关(P<0.01),而SAS得分与MPAI得分呈正相关(P<0.01);核心自我评价对手机依赖有负向预测作用,焦虑对手机依赖有正向预测作用;焦虑在核心自我评价与手机依赖之间起部分中介作用,中介效应占总效应的比例为34.2%。结论:核心自我评价是影响手机依赖的重要因素,能够直接对手机依赖产生影响,也可通过焦虑间接对手机依赖产生影响。

Objective： To explore the intermediary effect of anxiety between the core self-evaluation and the cell phone dependence in college students. Methods： Totally 759 college students were collectively measured by the Mobile Phone Addiction Index Scale （MPAI）,the Self-Rating Anxiety Scale （SAS） and the Core Self-evaluation Scale （CSES）. Results： The mobile phone dependence screen positive rate was 73.0% in this sample.The scores of the CSES were lower in the dependent group than in the non-dependent group,and the scores of the anxiety scale were higher in the dependent group than in the non-dependent group （ P 〈0.001）.The scores of CSES and the scores of MPAI were negatively correlated in college students （ P 〈0.01）,while the scores of SAS and MPAI were positively correlated in college students （ P 〈0.01）.Core self-evaluation had negatively predictive effect on mobile phone dependence,and anxiety had positive effect on mobile phone dependence.There were the part intermediary role of anxiety between the core self-evaluation and mobile phone dependence,and the mediating effect accounted for 34.2% of the total effect. Conclusion： Core self-evaluation may be an important factor affecting mobile phone dependence,which could directly influence mobile phone dependence directly,or indirectly influence mobile phone dependence through anxiety.
