Psychometric properties of the Duke Religion Index applied in a virtual platform

Abstract Introduction The Duke Religion Index (DUREL) is a brief instrument for the assessment of organized, non-organized and intrinsic religiosity. It’s been increasingly used on mental and public health studies in the recent years. The use of virtual platforms for data collection can be an alternative to its research context in the public health. Objective This study aims to assess the psychometric properties of DUREL applied in a virtual platform. Methods We studied 253 adults assessed through a series of online questionnaires, including DUREL. We compared the scores of atheists/agnostics, catholic, evangelicals and participants with other religions in the scale and calculated its internal consistency, factorial structure and correlations with other measures. Results The DUREL applied in virtual platform presented moderate-high internal consistency, factorial structure of a single component and associations with sociodemographic and mental health variables. Conclusion The results suggest that the psychometric properties of the DUREL applied in an online platform are similar to the conventional application.
