Abstract. The current study proposed the adaptation of the Utrecht-Management of Identity Commitments Scale (U-MICS) to the religious domain as an instrument to measure both individuals’ religious identity formation processes (when a variable-centered approach is adopted) and religious identity statuses (when a person-centered approach is adopted). The scale has been tested on a sample of 727 Italian participants aged 13–65 years, by collecting evidence of score structure, convergent, and criterion-related validity. Regarding the score structure validity, we confirmed that religious identity formation consists of three processes (commitment, in-depth exploration, reconsideration of commitment) and that, by using these scores, individuals can be placed into five different religious identity clusters (achievement, diffusion, foreclosure, moratorium, searching moratorium). As to the convergent and criterion-related validity, we tested the relationship that the three factors (religious identity formation processes) and the five clusters (religious identity statuses) have with religiousness and subjective well-being, respectively. Results indicate that the instrument is a promising tool to measure religious identity. Future studies should test this scale in other countries and with people from diverse religious traditions.
