大学生冲动性与攻击行为的关系：执行功能和正念的平行中介作用

The Relationship between Impulsivity and Aggressive Behavior in College Students: Parallel Mediating Roles of Executive Function and Mindfulness

摘要: 目的：基于一般攻击模型，从认知和情绪感双路径的视角考察执行功能和正念在大学生冲动性与主动性、反应性攻击之间的中介作用。方法：通过线上收集数据的方式，以627名大学生为被试，采用反应性与主动性攻击问卷、Barratt冲动性问卷、TEXI青少年执行功能问卷、五因素正念量表。结果：1) 相关分析显示，大学生冲动性、大学生主动性、反应性攻击行为、执行功能两两显著正相关，且均与大学生正念显著负相关。2) 多群组路径分析显示，性别对这一中介模型没有显著的影响。3) 中介效应检验表明，大学生的冲动性不仅直接影响其主动性和反应性攻击行为，还通过执行功能缺陷的单独中介影响主动性、反应性攻击行为；而正念仅在冲动性和主动性攻击行为之间起中介作用。结论：执行功能缺陷和正念在大学生冲动性和主动性攻击之间起并列中介作用。

Abstract: Objective: Based on the general aggression model, to investigate the mediating role of executive function and mindfulness between impulsivity and proactive and reactive aggression in college students from the perspective of cognitive and emotional dual pathways. Methods: Through online data collection, 627 college students were used as subjects, and the Reactive-Proactive Aggression Questionnaire, the Barratt Impulsivity Questionnaire, the TEXI Adolescent Executive Function Questionnaire, and the Five Facet Mindfulness Questionnaire were used. Results: 1) Correlation analysis showed that college students’ impulsivity, college students’ proactive aggressive behavior, reactive aggressive behavior and executive function were significantly positively correlated, and all of them were significantly negatively correlated with college students’ mindfulness. 2) Multi-group path analysis showed that gender had no significant effect on this mediation model. 3) The mediation effect test shows that the impulsivity of college students not only directly affects the proactive and reactive aggressive behavior, but also affects the proactive and reactive aggressive behavior through the independent mediation of executive function deficit; Mindfulness only mediates between impulsivity and proactive aggressive behavior. Conclusions: Executive dysfunction and mindfulness play a parallel mediating role between impulsivity and proactive aggression in college students.
