Psychopathy and institutional outcome in patients with schizophrenia in forensic settings in the UK

This study examined the institutional outcomes (12 weeks post-admission) of 134 male patients with DSM-IV schizophrenia assessed using the Psychopathy Checklist: Screening Version (PCL: SV) in a medium secure unit in the UK. High psychopathy scorers (HP) were more likely to be violent, non-compliant with programmes, engage in substance misuse violations, have criminal attitudes/peers and have low levels of insight into risk and violence. Psychopathy was also a modest predictor of institutional outcome in these domains.
