Findings on executive functioning in psychopathy are inconsistent. Different associations between psychopathy dimensions and executive functioning might explain contradicting findings. This study examined the role of psychopathy dimensions and types of aggression in response inhibition among 117 male adolescents (53 antisocial delinquents and 64 controls). Participants completed a self-report measure of aggression and a GoNoGo task. Psychopathy dimensions were assessed using the Psychopathy Checklist: Youth Version. Although high scores on the antisocial dimension and reactive aggression were associated with poor response inhibition, the affective-interpersonal dimension, proactive aggression, and verbal intelligence (IQ) were related to better response inhibition (two-factor model). Associations with the affective-interpersonal dimensions did not reach significance. Exploratory analyses showed that affective and antisocial facets accounted for the obtained opposing associations of the affective-interpersonal and antisocial psychopathy dimensions with response inhibition. The interpersonal and lifestyle facets (four-facet model) were unrelated to response inhibition. Results could not be explained by Attention Deficit Hyperactivity Disorder (ADHD). Findings suggest differential associations between the psychopathy dimensions, types of aggression, and response inhibition. Therefore, a dimensional approach to psychopathy and related concepts, such as aggression, might strongly improve diagnostic procedures. Global scores could mask important differential associations.
研究发现，精神变态者的执行功能存在不一致性。精神变态维度与执行功能之间的不同关联可以解释相互矛盾的发现。本研究考察了 117 名男性青少年（53 名反社会少年犯和 64 名对照组）中精神变态维度和攻击类型对反应抑制的作用。参与者完成了一项关于攻击性的自我报告测量和 GoNoGo 任务。使用青少年版心理变态检查表评估心理变态维度。尽管反社会维度和反应性攻击的高分与反应抑制不良相关，但情感-人际维度、主动性攻击和言语智力（智商）与更好的反应抑制相关（两因素模型）。与情感-人际维度的关联没有达到显著水平。探索性分析表明，情感和反社会方面解释了情感-人际和反社会心理变态维度与反应抑制之间获得的相反关联。人际和生活方式方面（四方面模型）与反应抑制无关。注意力缺陷多动障碍（ADHD）无法解释研究结果。研究结果表明，精神变态维度、攻击类型和反应抑制之间存在不同的关联。因此，对精神变态和相关概念（如攻击性）进行维度方法可能会极大地改善诊断程序。总体得分可能会掩盖重要的差异关联。
