Abstract
Three studies that evaluate the reliability and validity of the Extended Version of the Objective Measure of Ego Identity Status (Adams and Grotevant, 1983) are reported. In Studies 1 and 2, college students in Texas and Utah, respectively, completed the identity measure, the Extended Range Vocabulary Test, and the Crowne-Marlowe Social Desirability Scale and released achievement results from their college records. The identity measure was found to have acceptable reliability (both internal consistency and test-retest) and validity (content, factorial, discriminant, and concurrent). In Study 3, scale scores from the objective identity measure correlated in the predicted pattern with ratings of identity exploration and commitment made from the Ego Identity Interview. Although the objective measure is not intended to replace the interview, it would appear to be useful in a number of situations where administration of the interview is impractical.
