ABSTRACT

Polyvictimization, moral disengagement, impulse control, and hostility are all risk factors for violent offending. The present study tested a multiple mediation model to identify pathways leading from polyvictimization early in life to violent offending risk in adulthood. The Pathways to Desistance data were used in analyses. Group-based trajectory modeling was utilized to identify developmental heterogeneity in moral disengagement during adolescence. Generalized structural equation modeling was used to estimate multiple mediation pathways. Results indicated that a two-group moral disengagement model best fit the data. Increased polyvictimization scores at baseline predicted increased risk for violent offending in adulthood. This relationship was mediated by differential development of moral disengagement, hostility in adulthood, and impulse control in adulthood. The full path running from polyvictimization to differential development of moral disengagement to impulse control to violent offending was found to be significant. These findings indicate that polyvictimization may lead to high and chronic levels of moral disengagement, which may then lead to diminished impulse control, and that this entire sequence may increase violent offending risk.

摘要

多重伤害、道德脱离、冲动控制和敌意都是暴力犯罪的危险因素。本研究测试了一种多重中介模型，以确定从生命早期的多重受害到成年后的暴力犯罪风险的途径。Pathways to Desistance 数据用于分析。基于群体的轨迹模型被用来识别青春期道德脱离的发展异质性。广义结构方程模型用于估计多种中介途径。结果表明，两组道德脱离模型最适合数据。基线时多受害分数的增加预测成年后暴力犯罪的风险增加。这种关系是由道德脱离的差异发展、成年期的敌意、以及成年后的冲动控制。发现从多重受害到道德脱离到冲动控制再到暴力犯罪的差异发展的完整路径是重要的。这些发现表明，多重受害可能导致高度和长期的道德脱离，进而导致冲动控制减弱，并且整个过程可能会增加暴力犯罪的风险。
