Assessing spirituality/religiosity in the treatment environment: the Treatment Spirituality/Religiosity Scale.

There has been much interest in measuring and evaluating the role of spirituality/religiosity (S/R) in substance use disorder (SUD) treatment. This study presents the initial evaluation of a new measure of S/R in the treatment environment: the Treatment Spirituality/Religiosity Scale (TSRS). The TSRS has 10 items and can be completed by both patient and staff to measure the emphasis on S/R in a given treatment program, which may have important implications for patient-program fit. Data on the TSRS were gathered from 3,018 patients and 329 staff members from 15 residential SUD treatment programs within the Department of Veterans Affairs Health Care System. The TSRS showed good internal consistency (alpha = .77), a single-factor structure, close agreement between patients and staff members (r = .93), and good discriminant validity. The TSRS appears to be a brief, easily administered, and potentially useful measure of the emphasis on S/R in residential SUD treatment programs.
