Externalizing pathology and the five-factor model: a meta-analysis of personality traits associated with antisocial personality disorder, substance use disorder, and their co-occurrence.

In this meta-analysis we examined Five-Factor Model of personality (FFM) characteristics of externalizing disorders. Two pathologies, Antisocial Personality Disorder (APD) and Substance Use Disorder (SUD), have significant levels of co-occurrence that may be due to shared personality traits. Results from 63 samples (N = 15,331) were analyzed in order to summarize and compare five-factor results for APD, SUD, and co-occurring APD/SUD. Shared and unique personality features were identified at both the domain and the facet level of the FFM. Moderation analyses indicated that sample source (clinical versus community) and diagnosis (psychopathy versus DSM-based APD) accounted for some of the variability at the domain level. Results are discussed with respect to personality and externalizing disorders.
