Psychopathic dispositions and emotion dysregulation: A dual-disposition model perspective

The Dual-Disposition Model proposes to understand psychopathy through two dispositions (i.e., threat sensitivity and poor inhibitory control) with distinct etiological substrates. In the current study, we examined the predictive contributions of threat sensitivity, poor inhibitory control, and their interaction to emotion dysregulation in 694 Chinese undergraduates based on the Disinhibition subscale of Triarchic Psychopathy Measure, Behavioral Inhibition System Scale, and Difficulties in Emotion Regulation Scale. Our results suggested that two dispositions have independent contributions to emotion dysregulation. Additionally, interactive effects of two dispositions were found for emotion awareness, impulse control, emotional acceptance, and limited emotion regulation strategies when upset. These provide evidence that deficits associated with poor inhibitory control can be selectively suppressed by low threat sensitivity or exacerbated by high threat sensitivity. Training individuals with high psychopathic dispositions to focus on their emotional state might be able to enhance their ability of emotion regulation.
