Theoretical framework: 5-item measure of religiosity across three dimensions: organizational religious activity, non-organizational religious activity, and intrinsic religiosity.

Reliability: Published studies report good internal consistency, particularly for the intrinsic religiosity subscale.

Validity: Widely used in epidemiological and health-research studies examining religiosity as a variable.

Limitations: Imported from the OpenScales open item-bank project. This specific digital implementation has not been independently clinically validated by PsiQ — scores are for self-reflection, research, and educational purposes only.
