Psychometric properties of an Arabic translation of the shortest version of the Central Religiosity Scale (CRS-5) in a sample of young adults

Abstract

Background: There is a dearth of research on religiosity in Arabic-speaking populations, partly due to a lack of universal, standardized and valid instruments to assess this construct. We sought through this study to establish the psychometric properties of an Arabic translation of the shortest version of the Central Religiosity Scale (CRS-5), a widely used measure of religiosity that can be applicable to most religious traditions, thus allowing for worldwide cultural and trans-religious comparisons. Method: A total of 352 Lebanese young adults enrolled in this study with a mean age of 25.08 years (SD = 9.25) and 73.3% women. The forward-backward method was adopted to translate the original English version of the CRS-5 to Arabic. Results: We ran an Exploratory Factor Analysis for the CRS-5 to test whether the expected dimensionality is suitable for the subsequent Confirmatory Factor Analysis (CFA). The model found replicates the originally proposed five items and one-factor model. Our findings demonstrated that the Arabic CRS-5 achieved good levels of composite reliability, with a McDonald’s ω coefficient of.85. A multi-group CFA was modelled for the examination of measurement invariance of the Arabic CRS-5 across gender at the metric, configural, and scalar levels. Between-gender comparisons revealed no significant differences between males and females regarding CRS-5 scores. Finally, we found that religiosity was positively correlated with positive mental health aspects (i.e., social support) and inversely correlated with negative mental health aspects (i.e., suicidal ideation, depression, social anxiety and entrapment); thus attesting for the convergent validity of the CRS-5 as a measure of centrality of religiosity. Conclusion: Pending further validations with larger and more representative populations, we preliminarily suggest that the Arabic CRS-5 is psychometrically sound, and can be recommended for use for research and clinical purposes in Arabic-speaking people of various religions and cultures.
