Erikson's psychosocial stage model posits that identity formation is a key developmental task for adolescents, and that successfully resolving the identity versus role confusion crisis at this time of life has important impacts on psychosocial development through adulthood. However, little empirical work has tested the consequences of early-life identity development for progression through the subsequent psychosocial stages in Erikson's model. The purpose of the present study was to test whether identity resolution measured during emerging adulthood predicted later developmental trajectories of intimacy, generativity, and integrity across adulthood. We used data from four cohorts of participants in the Rochester Adult Longitudinal Study (RALS; N = 1,224), with up to five assessments spanning the twenties through the sixties. Latent growth curve modeling was used to estimate developmental trajectories for intimacy, generativity, and integrity, and to test the association between emerging adulthood identity resolution and growth parameters for each psychosocial outcome. Findings suggested that individuals with higher emerging adulthood identity resolution also experienced high levels of intimacy, generativity, and integrity in emerging adulthood, and these levels remained consistently high across adulthood. In contrast, those with lower identity resolution in emerging adulthood experienced lower initial levels of intimacy, generativity, and integrity, but faster growth over time. As a result, these trajectories appeared to nearly converge by the time participants were in their sixties, suggesting that one's emerging adulthood identity has less importance over time, and that individuals who struggled more with identity formation in adolescence and emerging adulthood are able to make up for it later in life.
