Duke University Religion Index (DUREL)

This chapter presents a concise and comprehensive review of studies on the Duke University Religion Index (DUREL). DUREL is a succinct and focused instrument designed to measure religiosity through its three major components: organizational, non-organizational, and intrinsic. By addressing both external religious behavior and internal religious sentiments, the DUREL offers a thorough assessment of an individual’s religious experiences. DUREL has been validated across diverse languages and populations, including China, Iran, Portugal, and Turkey.
