The authors assessed all measures of religious commitment (N = 139) reported in research studies published in the American Journal of Psychiatry and Archives of General Psychiatry in 1978 through 1989 (N less than 35). For nearly two-thirds of the measures, the studies either made no hypotheses or reported no results concerning the relationship of religious commitment to mental health status. For the great majority of the measures assessed, the studies reported a positive relationship between religious commitment and mental health.
