Spiritual/Religious Perfectionism Scale in Iran: Psychometric Evaluation.

This article introduces a new self-report measure of perfectionism: the Spiritual/Religious Perfectionism Scale (SRPS). Following preliminary psychometric evidence for a 20-item SRPS (Besharat, 2017),  the present investigation examined the structure of the SRPS using exploratory factor analysis in study 1 (368 students: 181 men, 187 women) and confirmatory factor analysis in study 2 (384 community adults: 189 men, 195 women) in Iran. After exploratory factor analysis, we retained 14 items. Confirmatory factor analysis supported the SRPS-14's unidimensionality and invariance across sex and sample type. The SRPS-14's internal consistency, test-retest reliability, and construct validity including criterion, convergent, incremental, and discriminant were examined. The results provided preliminary evidence for the reliability and validity of the SRPS-14 as a measure of spiritual/religious perfectionism. It should be noted that the English-language translation of the items presented in this paper has not yet been validated in an English-speaking sample, but should be validated in future research.
