Identity Development in Adulthood: A Longitudinal Study

Identity status interviews involving five domains of life (religious beliefs, political ideology, occupational career, intimate relationships, and lifestyle) were conducted with 249 women and men at ages 27 and 36. The results on overall identity and domain-specific identities confirmed our general hypothesis as to the strengthening of the commitment process: (1) stability was higher in the identity statuses involving commitment (identity achievement and foreclosure) than in the statuses not involving commitment (identity diffusion and moratorium); (2) an increase in the salience of identity domains could be attributed to an increase in the commitment process; (3) transitions into identity statuses involving commitment were more frequent than transitions into statuses not involving commitment; indicating that both identity achievement and foreclosure might be end points of identity development. It was concluded that the results pointed to identity development in adulthood rather than to a random fluctuation in identity statuses over time.
