The Study of Adolescent Identity Formation 2000–2010: A Review of Longitudinal Research

Longitudinal research into personal and ethnic identity has expanded considerably in the first decade of the present century. The longitudinal studies have shown that personal identity develops progressively during adolescence, but also that many individuals do not change identity, especially ethnic identity. Researchers have found rank‐order stability of personal identity to be larger in adulthood than in adolescence and stability of ethnic identity to be larger in middle and late than early adolescence. Personal identity appears to progress in adulthood, as well. Adolescents with a mature identity typically show high levels of adjustment and a positive personality profile, live in warm families, and perform well at school. There is little evidence for developmental order, however, and studies instead have mainly found covariation over time between identity and the other developmental processes. The present review demonstrates that the dimensional approach to the study of identity formation can be very successful. It allows for combined variable and person‐centered analyses, and for empirically generated and replicable statuses. Theoretically, the review suggests that identity formation is a less dynamic process than commonly assumed, that the identity status continuum has the order diffusion (D)→moratorium (M)→foreclosure (F)→achievement (A), that adolescents may follow two distinct sets of identity transitions on this continuum: D→F (or EC: early closure, an alternative label for foreclosure)→A or D→M→C (closure, a subtype of early closure)→A, that present identity status research offers multiple ways to study continuity of identity, and that there is no empirical proof for the assumption that exploration precedes commitment in the process of identity formation. Additionally, narrative identity research became highly visible between 2000 and 2010. The studies into narrative identity have shown that continuity of identity and coherence of the life story both grow in adolescence. Suggestions for future research are outlined.
