Abstract
While psychopathy has been a topic of interest in the psychological field for a long time, it is still unclear which developmental factors are related to its onset. Theories have suggested that experiencing trauma in childhood may contribute to the development of psychopathic traits. Experiencing trauma may also contribute to the development of an insecure attachment style, which in turn might cause the emergence of psychopathic traits. The current study investigated links between experiencing childhood trauma and the three psychopathy domains of the Extended Levenson Self-Report Psychopathy scale (E-LSRP; Egocentricity, Callousness, and Antisocial), and whether these links were mediated by the four insecure attachment dimensions of the Attachment Style Questionnaire (ASQ; Need for Approval, Preoccupation with Relationships, Relationships as Secondary, and Discomfort with Closeness), in a large sample of non-clinical participants (N = 2023, Mage = 32.7, 70.0% female). The results suggested that Relationships as Secondary, but not Discomfort with Closeness, positively mediated the relationship between childhood trauma and the three domains of psychopathy, while Need for Approval negatively mediated this relationship. Preoccupation with Relationships was a significant mediator in the links between childhood trauma and both the Egocentricity and Antisocial domains, but not the Callousness domain. The current findings suggested that there might be both shared and differential mechanisms linking childhood trauma and psychopathic traits through insecure attachment styles. These findings can guide further investigations in longitudinal research.
