Self-Rating of religiosity (SRR) in Iran: validity, reliability, and associations with the Big Five

The present research aimed to examine the psychometric properties of the Self-Rating of Religiosity (SRR) in Iran. In addition, the associations between the Persian version of this single-item measure of religiosity and the Big Five personality dimensions were investigated. Study 1 (n = 51) suggested that the Persian translation of the SRR had adequate test-retest reliability over a three-week period. Study 2 (n = 228) provided evidence for good convergent validity of the SRR, indexed by strong positive associations with scores on the Duke University Religion Index (DUREL). The Big Five dimensions of personality were measured using the Ten-Item Personality Inventory (TIPI). Moreover, the scores on the SRR were positively associated with Agreeableness (r = .23, p < .01) and Conscientiousness (r = .16, p < .05), while negatively associated with Openness to Experience (r = -.25, p< .01). These findings are in line with cross-cultural findings on personality correlates of intrinsic religiosity. Limitations and future directions are discussed.
