Clinicians' knowledge of and sensitivity to religious issues have been questioned. The present study measures religious knowledge and willingness to utilize such knowledge in clinical practice. We administered a 41-item questionnaire testing religious knowledge and willingness to utilize such knowledge to 28 psychiatric clinicians. The mean religious knowledge score was 61% of the total possible score. In spite of low scores, only 33% of clinicians consistently refrained from initiating discussions of religious issues. Results support a low level of religious knowledge but do not support a contention that clinicians are insensitive to religious issues.
