The Santa Clara Strength of Religious Faith Questionnaire is a brief (10-item, or five-item short form version), reliable and valid self report measure assessing strength of religious faith and engagement suitable for use with multiple religious traditions, denominations, and perspectives. It has been used in medical, student, psychiatric, substance abuse, and among general populations nationally and internationally and among multiple cultures and languages. Brief non denominational self report measures of religious and faith engagement that have demonstrated reliability and validity are not common but can have potential for general utility in both clinical and research settings. This article provides an overview of the scale and current research findings regarding its use in both research and clinical practice.
