The present study reports on a preregistered investigation of the potential mediating role of the triarchic psychopathy components Boldness, Meanness, and Disinhibition for associations between childhood traumatic experiences (CTE) and aggression. Three nonclinical samples (total = 1,729; 1,176 women, 68.02%) completed self-report instruments of CTE, triarchic psychopathy traits, reactive and proactive aggression (Samples 1 and 2), and general aggression (Sample 3). Cross-sectional path analyses revealed that both Meanness and Disinhibition consistently mediated associations between CTE and aggression. These indirect effects were consistent across gender, even though the direct effect of Meanness on proactive aggression was stronger in men than in women (Samples 1 and 2). Finally, Boldness had weak negative associations with childhood traumatic experiences in all three samples, but no direct association with aggression. Taken together, these correlational findings suggest potential developmental mechanisms linking early traumatic experiences to adult aggression through elevated levels of psychopathic traits.
本研究报告了一项预先注册的调查，研究了三因素精神病态成分（大胆、卑鄙和去抑制）在儿童创伤经历（CTE）与攻击行为之间的关联中的潜在中介作用。三个非临床样本（共 1729 人，其中 1176 名女性，占 68.02%）完成了 CTE、三因素精神病态特征、反应性和主动性攻击（样本 1 和 2）以及一般攻击性（样本 3）的自我报告量表。横截面路径分析显示，卑鄙和去抑制都在 CTE 和攻击之间的关联中起中介作用。这些间接效应在性别之间是一致的，尽管卑鄙对主动性攻击的直接效应在男性中强于女性（样本 1 和 2）。最后，大胆与所有三个样本中的儿童创伤经历呈弱负相关，但与攻击行为没有直接关联。综上所述，这些相关研究结果表明，通过更高水平的精神病态特征，早期创伤经历与成年攻击行为之间可能存在潜在的发展机制。
