The Identity Status Continuum Revisited: A Comparison of Longitudinal Findings With Marcia's Model and Dual Cycle Models

The developmental continuum of identity status has been a topic of theoretical debate since the early 1980's. A recent meta-analysis and recent studies with dual cycle models lead to two conclusions: (1) during adolescence there is systematic identity maturation; (2) there are two continuums of identity status progression. Both continuums show that in general adolescents move from transient identity statuses to identity statuses that mark the relative endpoints of development: from diffusion to closure, and from searching moratorium and moratorium to closure and achievement. This pattern can be framed as development from identity formation to identity maintenance. In Identity Status Interview research using Marcia's model, not the slightest indication for a continuum of identity development was found. This may be due to the small sample sizes of the various studies leading to small statistical power to detect differences in identity status transitions, as well as developmental inconsistencies in Marcia's model. Findings from this review are interpreted in terms of life-span developmental psychology.
