Abstract

Background: There is growing interest in studying the impact of religion/spirituality (R/S) on mental/physical health in Iran; however, little attention has been paid to the role of R/S in addiction. Objectives: This study aim to evaluate the reliability and construct and convergent validity of the Farsi version of the religious commitment inventory-10 (RCI-10) in a sample of substance abusers. Patients and Methods: The original English version of RCI-10 was translated into Farsi, the official language of Iran, using standard forward-backward translation. The reliability of the Farsi version was evaluated by assessing internal consistency; convergent validity was assessed via correlations with other measures of religiosity. Principal component analysis was utilized to assess the construct validity of the measure. Results: The Farsi version of RCI-10 had high internal consistency and satisfactory convergent validity. Factor analysis revealed a three-factor solution for the scale. Conclusions: The results of this study, while preliminary, suggest that the Farsi version of the RCI-10 is a reliable and valid measure of religiosity and can be used in health research with Farsi-speaking populations.
