暴力暴露对青少年攻击行为的影响：一个有调节的中介模型

The Influence of Violence Exposure on Adolescent Aggressive Behavior: A Moderated Mediation Model

摘要: 目的：探讨暴力暴露与青少年攻击行为的关系，并在此基础上提出一个有调节的中介模型，考察道德推脱的中介作用和父母心理控制的调节作用。方法：以363名山东省临沂市初中生为被试，采用父母心理控制量表、AQ攻击问卷、暴力暴露问卷、道德推脱问卷，以班级为单位进行集体施测。结果：(1) 暴力暴露与道德推脱、攻击行为两两之间均呈显著正相关。(2) 道德推脱在暴力暴露与攻击行为的关系中起部分中介作用(β = 0.13, p < 0.001)。(3) 父母心理控制调节暴力暴露通过道德推脱对攻击行为影响的后半段中介路径，父母心理控制水平高的个体，道德推脱对攻击行为的正向预测作用会更大(β = 0.18, p < 0.001)；父母心理控制水平低的个体，道德推脱对攻击行为的正向预测作用会变小(β = 0.08, p < 0.001)。结论：暴力暴露对青少年攻击行为有重要影响，道德推脱起到部分中介效应，父母心理控制在中介效应后半段路径起到调节作用。

Abstract: Objective: To explore the relationship between violence exposure and adolescent aggressive behavior, and propose a moderated mediation model to examine the mediating role of moral disengagement and the moderating role of parental psychological control. Methods: A total of 363 junior high school students from Linyi City, Shandong Province, were recruited. Measures included the Parental Psychological Control Scale, AQ Aggression Questionnaire, Violence Exposure Questionnaire, and Moral Disengagement Questionnaire. Group testing was conducted by class. Results: (1) Violence exposure was significantly positively correlated with moral disengagement and aggressive behavior. (2) Moral disengagement partially mediated the relationship between violence exposure and aggressive behavior (β = 0.13, p < 0.001). (3) Parental psychological control moderated the latter half of the mediating path through which violence exposure influenced aggressive behavior via moral disengagement. Higher parental psychological control strengthened the positive predictive effect of moral disengagement on aggressive behavior (β = 0.18, p < 0.001), while lower parental psychological control weakened this effect (β = 0.08, p < 0.001). Conclusion: Violence exposure significantly impacts adolescent aggressive behavior, with moral disengagement serving as a partial mediator. Parental psychological control moderates the latter half of the mediating path.
