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 N = 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.

精神病态特征在解释童年创伤经历和攻击性之间的关联中的作用。

本研究报告了一项预先注册的调查，调查了三元精神病成分大胆、卑鄙和去抑制对儿童创伤经历 (CTE) 和攻击性之间关联的潜在中介作用。三个非临床样本（总 N = 1,729；1,176 名女性，68.02%）完成了 CTE、三元精神病特征、反应性和主动性攻击（样本 1 和 2）以及一般攻击（样本 3）的自我报告工具。横断面路径分析显示，卑鄙和去抑制始终介导 CTE 和攻击性之间的关联。这些间接影响在不同性别之间是一致的，尽管卑鄙对主动攻击的直接影响在男性中比在女性中更强（样本 1 和 2）。最后，在所有三个样本中，胆量与童年创伤经历的负相关性较弱，但与攻击性没有直接关联。综上所述，这些相关性研究结果表明，通过提高精神病性特征水平，将早期创伤经历与成人攻击性联系起来的潜在发展机制。
