Validation of the Arabic and Hebrew versions of the Utrecht-Management of Identity Commitments Scale (U-MICS)

Introduction: The Utrecht-Management of Identity Commitments Scale (U-MICS; Crocetti, Rubini, & Meeus, 2008) is a self-report scale that can be applied to measure three identity processes (commitment, in-depth exploration, and reconsideration of commitment) in specific domains. The current study was aimed at testing the applicability of the U-MICS in two new languages: Arabic and Hebrew. Specifically, we (a) tested the fit of the three-factor structure; (b) examined measurement invariance of the Arabic and Hebrew versions; and (c) investigated convergent validity by relating the identity processes (commitment, in-depth exploration, and reconsideration of commitment) to multiple indicators of psychosocial adjustment (self-esteem, prosocial behaviors, and delinquency). Methods: Participants were 314 Arab and 386 Jewish adolescents living in Israel (N = 770; 54.7% girls; M_age = 13.79, SD_age = 0.51, age-range = 12–15). Assessments of identity processes, self-esteem, and delinquency were collected using self-report measures, while prosocial behaviors were measured through peer nominations. Results: The results highlighted that (a) the three-factor model fit the data excellently in the total sample as well as in Arab and Jewish samples; (b) hierarchical levels of measurement invariance (configural, metric, and scalar), as well as invariance of covariances, could be clearly established; and (c) convergent validity was demonstrated by showing meaningful associations between identity processes and indicators of psychosocial functioning. Conclusions: This study indicates that the U-MICS is a reliable instrument for assessing identity processes in Arabic and Hebrew-speaking adolescents.
