The Duke University Religion Index (DUREL): A Five-Item Measure for Use in Epidemological Studies. Religions, 1, 78-85. Self The Duke Religion Index (DUREL) is a five item scale which measures religiosity in three areas: organizational religiosity (OR), non-organizational religiosity (NOR), and intrinsic religiosity. Two of the questions were derived from large epidemiologic studies and have been shown to have a strong predictive value for many health outcomes. OR has been related to less depression, more social support, better physical health, lower resource utilization, and lower mortality. NOR has been shown to be related to poorer physical health, and greater social support. The other three items were taken from the Hoge 10- item religiosity scale (Hodge et al 1972). The DUREL has high test-retest reliability (intra-class correlation = 0.91), high internal consistency (Cronbach's alpha's = 0.78--0.91).
