    This study validates an existing spirituality measure-the intrinsic spirituality scale (ISS)-for use with Muslims in the United States. A confirmatory factor analysis was conducted with a diverse sample of self-identified Muslims (N = 281). Validity and reliability were assessed along with criterion and concurrent validity. The measurement model fit the data well, normed χ2 = 2.50, CFI = 0.99, RMSEA = 0.07, and SRMR = 0.02. All 6 items that comprise the ISS demonstrated satisfactory levels of validity (λ > .70) and reliability (R2 > .50). The Cronbach's alpha obtained with the present sample was .93. Appropriate correlations with theoretically linked constructs demonstrated criterion and concurrent validity. The results suggest the ISS is a valid measure of spirituality in clinical settings with the rapidly growing Muslim population. The ISS may, for instance, provide an efficient screening tool to identify Muslims that are particularly likely to benefit from spiritually accommodative treatments.
