道德推脱与攻击行为关系的元分析

运用元分析技术, 探讨了道德推脱与攻击行为之间的关系及可能存在的调节变量。41项研究的44个独立样本满足了元分析研究标准, 被试总人数为24536名。元分析结果显示, 道德推脱与攻击行为之间存在着中等程度的正相关(r = 0.35, 95%CI为[0.30, 0.39]), 文化背景、数据特点、道德推脱问卷类型、攻击行为类型、年龄阶段会对道德推脱与攻击行为之间的关系产生显著的调节效应。但出版情况、被试类型不会对道德推脱与攻击行为之间的关系产生显著的调节效应。结果表明, 道德推脱是攻击行为的有效预测变量。

A Meta-Analysis of the Relationship between Moral Disengagement and Aggressive Behavior

A growing body of research has demonstrated consistent links between moral disengagement and aggressive behavior. Meta-analytic procedures were used to test the effects of moral disengagement on aggressive behavior. The studies were searched from 1996 to 2013, which were written in Chinese and English. A total of 41 relevant studies met the criteria for inclusion in the meta-analysis. All studies included 44 independent samples and 24536 participants. Pearson’s r was used as the effect size metric. The Comprehensive Meta-Analysis (CMA) Version 2 program was used to analyze the data. Moderator analyses were also conducted. The meta-analytic findings indicated a positive overall effect (r = 0.35, 95% CI [0.30, 0.39]), supporting the hypothesis that moral disengagement is a significant correlate of aggressive behavior. Furthermore, the results of the moderator analyses indicated that cultural differences, data features, the moral disengagement measure used, type of aggression, and age grades all moderated the positive relationship between moral disengagement and aggressive behavior. In addition, the correlation between moral disengagement and aggressive behavior was larger in Chinese culture as compared to western culture. Finally, implications for aggression are suggested.
