With the introduction by E. H. Erikson (1968) of “Identity: Youth and Crisis”, and J.E. Marcia’s (1966) construction of the “identity status paradigm,” investigators have been interested in measuring identity diffusion, foreclosure, moratorium and achievement statuses. To address this need The Objective Measure of Ego-Identity Status (OMEIS; Adams, Shea & Fitch, 1979) was developed to assess identity status in adolescence and young adults. Four original validation studies were completed for the measure and it has been widely used for thirty years. More recently Adams (2010) has prepared a manual that includes a history of the theoretical underpinnings of the use of the Objective Measure of Ego-Identity Status, a summary of several longitudinal studies to further validate the theoretical underpinnings of psychological differentiation and integration, the inclusion of new items and a description of a new validation study, and details on scoring criteria. Beyond a comprehensive presentation of a theoretical view of the nature of socialization and identity formation, a summary of seven studies are reviewed that support many tenets of the theoretical framework. This includes a description of the construction and use of the original version of the OMEIS in several validation and three important longitudinal studies. Given the thirty years of use of the original measure and continuing interest in its applications a validation of new items has been completed. A random sample of 2000 entering university students was contacted using internet methodologies. Of the 2000 students contacted, 1620 completed the validation study. Twenty four new or modified items were constructed to measure the four identity statuses. These items continue to measure occupational, political and religious ideological aspects of ego-identity and are used to compute a participant’s scores into a diffusion, foreclosure, moratorium, or identity achievement status. A factor analysis of the items revealed four factors reflecting the four identity statuses. Alphas ranged from .84 to .90 for the four ego-identity status factors. Predictive validity revealed that moratorium and achievement status youth had significantly higher global identity and lower authoritarianism scores than diffusion and foreclosure students. Foreclosed and achieved identity students were significantly more self-accepting than diffused or moratorium identity status peers. Identity achievement students were significantly lower in rigidity of thought than the remaining three identity status students. Analyses were computed to test for gender, age, program, and living arrangement differences for students on their identity status scores. No significant main or interactions effects were observed. The new modifications and revisions of the 24 items are judged to have satisfactory construct validity, reliability, and predictive validity
