Analysis of the mediating role of self-control among Chinese college students between physical activities and aggressive behavior

This study aims to explore the mediating role of self-control in the relationship between physical activity and aggressive behavior among college students. And it provides a basis for the prevention and control of aggressive behavior among college students. In terms of the methods, this study employs Physical Activity Rating Scale (PARS-3), Self-Control Scale (SCS) and Chinese version of Buss&Perry aggression questionnaire (AQ-CV) on 950 college students. And mediating effect test and Bootstrap analysis are applied. The analyses yielded the following findings. (1) Physical activity is significantly negatively correlated with aggressive behavior and self-control (r=-0.18, 0.24; P＜0.01) and self-control is positively correlated with aggressive behavior (r=-0.47; P＜0.01). (2) Physical activity not only negatively predicts college students' aggressive behavior (B=-0.08; P<0.01), but also positively predicts self-control (B=0.24; P<0.01) Self-control negatively predicts college students' aggressive behavior (B=-0.52; P<0.01). Self-control plays the mediating role in the relationship between physical activity and aggressive behavior among college students, with the ratio of 60.29%. It is concluded that physical activity can not only directly improve the problem of aggressive behavior among college students, but also indirectly improve it through self-control.

本研究旨在探讨自我控制在大学生体育活动与攻击行为之间关系中的中介作用，为大学生攻击行为的防控提供理论依据。在研究方法层面，本研究采用体育活动评定量表（Physical Activity Rating Scale, PARS-3）、自我控制量表（Self-Control Scale, SCS）以及中文修订版Buss&Perry攻击问卷（Chinese version of Buss&Perry aggression questionnaire, AQ-CV），对950名大学生进行施测，并运用中介效应检验与Bootstrap分析法开展数据分析。本研究得到如下结果：（1）体育活动与攻击行为、自我控制均呈显著相关（r=-0.18、0.24；P＜0.01），自我控制与攻击行为呈显著正相关（r=-0.47；P＜0.01）；（2）体育活动不仅可负向预测大学生的攻击行为（B=-0.08；P<0.01），还可正向预测自我控制（B=0.24；P<0.01），同时自我控制负向预测大学生的攻击行为（B=-0.52；P<0.01）。自我控制在大学生体育活动与攻击行为的关系中发挥中介作用，中介效应占比为60.29%。综上可知，体育活动既可直接改善大学生攻击行为问题，亦可通过自我控制这一中介变量间接改善该问题。
