The present meta-analysis explored the predictive utility of the Psychopathy Checklist: Youth Version at the facet level, namely the relation between the interpersonal, affective, lifestyle, and antisocial facets with violent and general recidivism. We included data from 12 manuscripts and 16 independent samples drawn exclusively from longitudinal study designs. Only the lifestyle and the antisocial facets were significantly related to both outcomes (General: rw = 0.15, p = .023 and rw = 0.22, p < .001, respectively. Violent: rw = 0.17, p = .003 and rw = 0.24, p < .001, respectively). Additional analyses from multivariate results revealed contrasting lower effect sizes (not exceeding rw = 0.05), which suggests the shared variance between the facets is more important for predicting recidivism than their independent effect. Finally, our moderation analyses showed that longer follow-ups resulted in lower predictive effects among some facets, suggesting the malleability of psychopathic traits in youth.
