Influence of spirituality and religiousness on substance misuse in patients with schizophrenia or schizo-affective disorder.

Substance misuse represents a major issue in the treatment of schizophrenia patients. Spirituality and religiousness have been shown to reduce substance misuse and to foster recovery among substance misusers in the general population. One hundred and fifteen stabilized outpatients with schizophrenia (mean age 39; 70% male) were selected in 2004 for an interview about religious coping. Religious involvement was significantly inversely correlated to substance use and abuse. A content analysis showed that religion may play a protective role toward substance misuse in 14% of the total sample, especially for patients who had stopped substance misuse (42%). It played a negative role in 3% of cases. Religion may play a role in the recovery of schizophrenia patients with substance misuse comorbidity.
