Studies indicate that religious and spiritual dimensions are positively related to all forms of mental health, including indicators of subjective well-being and personality factors. It has also been suggested that religious/spiritual well-being might play an important role in the development, course and recovery of mental illness. However, despite such claims, there have been numerous recordings of delusions and hallucinations adopting a religious nature. Furthermore, there is some evidence that religion and spirituality can be harmful for patients with psychosis.
Dimensions of religious/spiritual well being (RSWB; such as hope, forgiveness, or general religiosity) have been examined comprehensively, and its positive relation to subjective well-being has been confirmed. However, there also might be facets of RSWB linked to mental illness (e.g. delusional ideas).
