Development and validation of ego-identity status.

4 modes of reacting to the late adolescent identity crisis were described, measured, and validated. Criteria for inclusion in 1 of 4 identity statuses were the presence of crisis and commitment in the areas of occupation and ideology. Statuses were determined for 86 college male Ss by means of individual interviews. Performance on a stressful concept-attainment task, patterns of goal setting, authoritarianism, and vulnerability to self-esteem change were dependent variables. Ss higher in ego identity performed best on the conceptattainment task; those in the status characterized by adherence to parental wishes set goals unrealistically high and subscribed significantly more to authoritarian values. Failure of the self-esteem condition to discriminate among the statuses was attributed to unreliability in self-esteem measurement.
