Centrality of Religiosity Scale (CRS)
Also known as: Huber CRS, Centrality of Religiosity Scale, Religiosity Centrality Measure, CRS-15 / CRS-10 / CRS-7
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.
Key highlights
- Provides both a single centrality score and five interpretable dimension scores from a short instrument.
- Designed and validated for cross-cultural and interreligious comparison, not just Christian samples.
- Offers interchangeable 15-, 10-, and 7-item versions on a common metric, easing inclusion in larger surveys.
- Grounds its dimensions in the well-established Glock-Stark tradition while adding a clear second-order centrality construct.

When to use it
Use the CRS when you need a compact, validated general measure of how important religion is in a person's life and want both an overall index and a breakdown into intellect, ideology, public practice, private practice, and experience. It is well suited to large surveys, to cross-cultural and interreligious comparison, and to studies where a short instrument is required but multidimensional coverage is still wanted, thanks to its 15-, 10-, and 7-item forms. It is less appropriate when the research question targets a specific facet of religious motivation or content — such as intrinsic versus extrinsic orientation or fundamentalism — that the CRS deliberately abstracts away, or when the population's religion does not express itself through the five chosen dimensions.
Strengths & limitations
- Provides both a single centrality score and five interpretable dimension scores from a short instrument.
- Designed and validated for cross-cultural and interreligious comparison, not just Christian samples.
- Offers interchangeable 15-, 10-, and 7-item versions on a common metric, easing inclusion in larger surveys.
- Grounds its dimensions in the well-established Glock-Stark tradition while adding a clear second-order centrality construct.
- Compresses each dimension into very few items, limiting fine-grained measurement of any single facet.
- The three-level classification rests on conventional cut points that are pragmatic rather than absolute.
- Captures the centrality and frequency of religious expression but not its motivational quality or content.
- Cross-religious comparability still requires measurement-invariance testing in each new population rather than being assumed.

Frequently asked
What does 'centrality of religiosity' mean?
It refers to how central or important the religious meaning system is within a person's overall personality and life. Rather than asking only whether someone believes or attends services, the CRS gauges how strongly religion organizes a person's thinking, beliefs, public and private practice, and experience. A high centrality score indicates that the religious system is a dominant, chronically accessible part of the personality; a low score indicates it is peripheral.
What are the five dimensions the CRS measures?
The CRS measures intellect (engagement with and interpretation of religious questions), ideology (the firmness of religious belief), public practice (participation in communal worship), private practice (individual devotion such as prayer or meditation), and religious experience (perceived contact with a transcendent reality). These five descend from the Glock-Stark multidimensional tradition and are combined into a single higher-order centrality construct.
Which version of the CRS should I use?
The CRS comes in 15-, 10-, and 7-item forms placed on a common metric, so the choice depends on survey space and the level of dimensional detail required. The 15-item form gives the fullest measurement of each dimension; the 10- and 7-item forms are designed for situations where questionnaire length is constrained but a valid overall centrality score is still needed. For cross-cultural work, whichever form is chosen should be tested for measurement invariance before group means are compared.
