【摘要】 目的:探讨农村初中生日常环境中的暴力暴露与攻击性行为的关系，并在此基础上建立一个有调节的中介模型，探讨敌意认知的中介作用及冲动性特质的调节作用。方法:采用攻击性行为问卷、日常环境中的暴力暴露问卷、敌意认知问卷、冲动性问卷对721名农村初中生进行调查。结果:(1)相关分析结果表明，农村初中生的暴力暴露与攻击性行为(r=0.80,P<0.01)、敌意认知(r=0.77,P<0.01)、冲动性特质(r=0.33,P<0.01)均呈显著的正相关、攻击性行为与敌意认知(r=0.82,P<0.01)、冲动性特质(r=0.64,P<0.01)均呈显著的正相关、敌意认知与冲动性特质(r=0.62,P<0.01)呈显著的正相关；(2)日常环境中的暴力暴露显著正向预测攻击性行为，敌意认知在暴力暴露和攻击性行为之间存在显著部分中介效应；(3)冲动性特质对敌意认知的中介作用具有调节效应，并调节中介过程的后半路径，即敌意认知对攻击性行为的影响随着冲动性特质的增大而增大。结论:农村初中生日常环境中的暴力暴露通过敌意认知的中介作用影响攻击性行为，冲动性特质对敌意认知的中介作用具有调节效应。更多还原

【Abstract】 Objective:To explore the relationship between violent exposure and aggressive behavior in the daily environment of rural junior high school students, and on this basis to establish a moderated mediation model to explore the mediating role of hostile cognition and the moderating role of impulsivity.Methods:A total of 721 rural junior high school students were investigated by questionnaire of aggressive behavior, questionnaire of violent exposure in daily environment, questionnaire of hostile cognition and questionnaire of impulsiveness.Results:(1) The results of correlation analysis showed that there were significant ly positive correlations between violent exposure and aggressive behavior(r=0.80,P<0.01),hostile cognition(r=0.77,P<0.01),impulsivity(r=0.33,P<0.01);aggressive behavior and hostile cognition(r=0.82,P<0.01)and impulsivity(r=0.64,P<0.01)were positively correlated, while hostile cognition was positively correlated with impulsivity(r=0.62,P<0.01).(2) Violent exposure in daily environment significantly positively predicted aggressive behavior, and hostile cognition had a significantly partial mediating effect between violent exposure and aggressive behavior.(3)The mediating effect of impulsivity on hostile cognition was moderated, and the latter half of the mediating process was moderated, that is, the influence of hostile cognition on aggressive behavior increased with the increase of impulsivity.Conclusion:Exposure to violence in the daily environment of rural junior high school students affects aggressive behavior through the mediating effect of hostile cognition, and impulsivity has a moderating effect on the mediating effect of hostile cognition.更多还原
