The Duke University Religion Index (DUREL)

The Duke University Religion Index (DUREL) is a brief questionnaire designed to measure an individual's religious involvement. It assesses three aspects: organizational religious activity (such as church attendance), non-organizational activity (like private prayer), and intrinsic religiosity (how personally meaningful religion is to them). By capturing these dimensions, DUREL helps researchers understand how religion influences health, well-being, or social behaviors, providing a quick yet comprehensive snapshot of a person's religious engagement.
