This study investigated the relationship between identity status and structural dimensions of individuals' self-theories or personal construct systems. The sample was composed of 31 Achievers, 31 Moratoriums, 30 Foreclosures, and 26 Diffusions. Participants completed a modified version of Kelly's (1955) Role Construct Repertory test designed to assess their personal sense of integrative continuity over time. Status differences in self-construct differentiation, integration, and self-certainty were analyzed. Results indicated that Moratoriums and Diffusions had the highest self-construct differentiation. Achievers were the most self-certain in their ratings, Diffusions the least. Status differences in self-theory integration were found, but only when a qualitative, structural analysis of levels of self-construct differentiation and integration was performed. No sex effects were found. Results are discussed as replicating and extending previous work in the area, and future research directions are noted. © 1990.
