The purpose of this study was to compare identity formation in adolescents from Italian (n = 261), mixed (n = 100), and migrant families (n =148). Participants completed the Italian version of the Utrecht-Management of Identity Commitments Scale that assesses identity processes in educational and relational domains. Within a variable-centered approach we found that adolescents from migrant families reported significantly higher levels of reconsideration of commitment than did their peers from Italian and mixed families. Similarly, within a person-centered approach, adolescents from migrant families were more represented in the searching moratorium status than their counterparts from Italian and mixed families. Overall, these results indicated that migrant adolescents face more difficulties to define their personal identity.
