This document discusses identity development in adolescents. It begins by outlining Erik Erikson's stages of psychosocial development, with a focus on the 5th stage of identity vs. role confusion. It then explains James Marcia's identity status theory, which identifies four statuses along a continuum from identity diffusion to identity achievement based on exploration and commitment. The statuses are identity achievement, foreclosure, diffusion, and moratorium. Finally, it describes the process of identity consolidation in early, middle, and late adolescence as identities are de-structured, restructured, and tested.
