Validation of the Serbian Version of the Utrecht-Management of Identity Commitments Scale (U-MICS) in an Adult Population

The Utrecht-Management of Identity Commitments Scale (U-MICS) is a widely applied identity measure. It is used to assess the identity processes encompassed in the three-factor identity model (commitment, in-depth exploration, and reconsideration of commitment). The purpose of this study was to validate the Serbian version of the U-MICS in an adult population. Participants were 375 (73.3% females) Serbian adults aged from 18 to 65 years (M age = 33.75, SD age = 8.92). They completed the U-MICS along with self-reports of self-esteem and life satisfaction. The results of Confirmatory Factor Analyses indicated that the three-factor model fit the data very well and better than alternative one- and two-factor models. Furthermore, hierarchical levels of measurement invariance (configural, metric, and scalar) in sex and age groups could be established. Finally, convergent validity was demonstrated by showing meaningful associations between identity processes and indicators of psychosocial functioning (i.e., self-esteem and life satisfaction). This study documents the psychometric properties of the Serbian version of the U-MICS in a population of adults.
