The aim of this study was to investigate the relationships between standardized, factor-based measures of religiosity and personality/mental health. In a sample of 471 self-identified Christian subjects, 303 females and 168 males, 79 non-psychotic psychiatric in-patients and 392 non-patients, personal extrinsicness was partially positively correlated with the BCI Obsessive score. In multiple regression analyses some of the factor-based religious orientation indices related differently to the BCI Oral, Obsessive and Hysterical Scales and the SCL-90 Global Symptom Index as dependent variables. The religious orientations explained 8.8% of the variance of the BCI Oral Score, 4.2% of the BCI Obsessive score, 3.3% of the BCI Hysterical score, and 12.3% of the SCL-90 Global Symptom Index score. Of the doctrinal belief and morality indices only with Moral conservatism was significantly related to the BCI Hysterical score, and then negatively.
