Development and validation of Spiritual/Religious Perfectionism Scale: A preliminary study

The present study aimed to develop and examine psychometric properties of the Spiritual/Religious Perfectionism Scale (SRPS) including construct validity, convergent and discriminant validity, internal consistency, and test-retest reliability. Four hundred and sixty nine Iranian men and women (226 men, 243 women) participated in this study as volunteers. All participants were asked to complete the SRPS, Ego Strength Scale (ESS), Mental Health Inventory (MHI-28), and Positive and Negative Affect (PANAS). The results of exploratory factor analysis supported a general factor structure for the SRPS. The convergent and discriminant validity of the SRPS were supported by an expected pattern of correlations between the scale and the measures of ego strength, psychological well-being, psychological distress, and positive and negative affects. All correlation coefficients between the mean scores on the SRPS and scores of the ego strength, psychological well-being, psychological distress, and positive and negative affects were statistically significant. Coefficient alpha estimates of internal reliability were between .79 and .91 for the SRPS. Test-retest reliability of the SRPS was also calculated at the range of statistically significant of .73. It was concluded that the SRPS can be considered as a reliable and valid scale to measure spiritual/religious perfectionism in Iranian samples.
