Numerous commentators have noted a historic ambivalence between religion and psychiatry. However, a growing body of evidence indicates an association between mental health and various religious activities, both private and public. As such, there are growing calls for greater religious sensitivity among mental health clinicians, to help unlock the potentially healing aspects of religiosity. So far, most literature from English-speaking countries has focused on Christianity and mental health, with little attention paid to Muslim mental health. This is the fastest growing religion in English-speaking countries, and the mental health of Muslims in these countries is under-researched. As such, the present paper summarises new directions in the mental health and religion literature, with a focus on the mental health of Muslims in English-speaking countries.
