Centrality of Religiosity Scale (CRS)

The Centrality of Religiosity Scale (CRS), developed by Stefan Huber and Odilo Huber and consolidated in their 2012 paper, measures how central the religious meaning system is within an individual's personality. It operationalizes five core dimensions drawn from the Glock-Stark tradition — intellect, ideology, public practice, private practice, and religious experience — and treats them as indicators of a single higher-order construct, the centrality of religiosity. The CRS comes in interchangeable 15-, 10-, and 7-item versions, yields both dimension scores and an overall centrality score, and supports a simple three-level classification of respondents as not religious, religious, or highly religious. Designed for cross-cultural and interreligious use, it has become one of the most widely applied general religiosity measures in contemporary survey research.
