This study presents the validation of the short forms of Centrality of Religiosity Scale (CRS) in Georgia. This country offers a unique Christian orthodox context with a long-lasting religious tradition and strong affiliation to churches. Translated short forms were administered in the years 2012 (CRS-5) and 2018 (CRSi-7). Participants reported on ideological, intellectual, and experiential aspects of their faith and their private and public religious practice in face-to-face interviews. The collected data was subject to reliability analyses. Scale invariance over time was tested with the CRS-5, whereas the CRSi-7 was examined for model goodness, with one factor—Centrality of Religiosity—with a confirmatory factor analysis. Derived statistical coefficients from large stratified random populational samples (2012: N
= 2238 and 2018: N
= 1906) show good to acceptable Cronbach’s
= 0.73 and
= 0.67). The composite scores’ means and standard deviations contour norm values for further investigations in social sciences related to religiosity in Georgia. The results of the confirmatory factor analyses show that the Centrality of Religiosity manifests a stable factor, adequately explaining different dimensions of faith life. The high reliability of the CRS-5 over time leads to the conclusion of consistent measurement characteristics and thus, its suitability for longitudinal analysis. The CRSi-7 has a comparable model fit to the CRS-5 providing an alternative for interreligious contexts if needed. Aspects of assessment and analysis are discussed and reasons for the application of the longer version of the CRS are provided in the end.
