The validity of self-report psychopathy assessment has been questioned, especially in forensic settings where clinical evaluations influence critical decision-making (e.g., institutional placement, parole eligibility). Informant-based assessment offers a potentially valuable supplement to self-report but is challenging to acquire in under-resourced forensic contexts. The current study evaluated, within an incarcerated sample (n = 322), the extent to which brief prototype-based informant ratings of psychopathic traits as described by the triarchic model (boldness, meanness, disinhibition; Patrick et al., 2009) converge with self-report trait scores and show incremental validity in predicting criterion measures. Self/informant convergence was robust for traits of boldness and disinhibition, but weaker for meanness. Informant-rated traits showed incremental predictive validity over self-report traits, both within and across assessment domains. These findings indicate that simple prototype-based informant ratings of the triarchic traits can provide a useful supplement to self-report in assessing psychopathy within forensic-clinical settings.
自陈式精神病态评估的有效性一直受到质疑，尤其是在法医环境中，临床评估会影响关键决策（例如，机构安置、假释资格）。基于知情者的评估为自陈式评估提供了一个潜在的有价值的补充，但在资源匮乏的法医环境中获取这种评估具有挑战性。本研究在一个被监禁的样本（n=322）中评估了，简短的基于原型的知情者对三因素模型（大胆、卑鄙、去抑制；Patrick 等人，2009）所描述的精神病态特征的评分与自陈式特质评分的一致性程度，并在预测标准测量方面显示出增量有效性。大胆和去抑制特质的自我/知情者一致性较强，但卑鄙特质的一致性较弱。知情者评定的特质在自我报告特质内和跨评估领域均显示出增量预测有效性。这些发现表明，基于简单原型的三因素特质的知情者简单评分可以为法医临床环境中评估精神病态提供有用的自陈式评估补充。
