Samenvatting

A quasi-experimental research was used to examine the impact of violence and substance use disorder on social cognitive skills on patients with schizophrenia. A sample of 46 male patients was tested with the Reading Mind in the Eyes Test to assess their social cognitive skills. The present study does not show significant impacts with regard to violence, whereas a trend towards significance was found in the impact of substance use disorder on social cognitive skills. Patients who suffer from substance use disorder achieve better scores on the Reading Mind in the Eyes Test than those individuals who do not use substances. An interaction-effect of substance use disorder in violent and non-violent patients was not found. As patients with comorbidity with substance use disorder perform better in social cognition further research is prospected. Adaption of treatment should be assessed.
