On the Progression and Stability of Adolescent Identity Formation. A Five-Wave Longitudinal Study in Early-to-Middle and Middle-to-Late Adolescence
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.

The BFs as reported for RQ 1 in Table 2 (p. 1574) should have been BF 2,1 = 15,514 and BF2,unc = 21.41. The PMP values of M1, M2, and M3 should have been: < .001, .95 and .05, respectively. The conclusions from the analysis do not change because of the corrected results.
We elaborated on what went wrong in the following paper.
