This study examined identity development in a 5-wave study of 923 early-to-middle and 390 middle-to-late adolescents thereby covering the ages of 12-20. Systematic evidence for identity progression was found: The number of diffusions, moratoriums, and searching moratoriums (a newly obtained status) decreased, whereas the representation of the high-commitment statuses (2 variants of a [fore]closed identity: "early closure" and "closure," and achievement) increased. We also found support for the individual difference perspective: 63% of the adolescents remained in the same identity status across the 5 waves. Identity progression was characterized by 7 transitions: diffusion→moratorium, diffusion→early closure, moratorium→closure, moratorium→achievement, searching moratorium→closure, searching moratorium→achievement, and early closure→achievement. © 2010 The Authors.
