Summary	The Religious Orientation Scale (ROS), introduced by Gordon Allport and J. Michael Ross in 1967, is the instrument that operationalized Allport's distinction between two motivational stances toward faith. The extrinsic orientation treats religion as a means to other ends — comfort, security, social standing — while the intrinsic orientation treats faith as the master motive that the believer lives by. The ROS measures the two orientations on separate item sets rather than as opposite ends of one continuum, which means a respondent can score high, low, or moderate on each independently. Allport and Ross used this independence to build a fourfold typology, adding the 'indiscriminately proreligious' (high on both) and 'indiscriminately antireligious' (low on both) categories, and showed that orientation, not mere churchgoing, predicted prejudice.	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.
