Different methodologies in the assessment of identity: Congruence between self-report and interview techniques?

Convergent-divergent validity and reliability estimates for clinical interview and self-report measures of ego identity were obtained. Twenty-three males and 25 females completed an extended version of the Ego Identity Interview [H. D. Grotevant, W. Thorebecke, and M. C. Meyer (1982) "An Extension of Marcia's Identity Status Interview into the Interpersonal Domain,"Journal of Youth and Adolescence 11: 33-48] and the extended version of the Objective Measure of Ego Identity Status [H. D. Grotevant and G. R. Adams (1984) "Development of an Objective Measure to Assess Ego-Identity in Adolescence: Validation and Replication,"Journal of Youth and Adolescence, 13: 419-438]. While the two measures were expected to converge, little convergence was observed. The findings suggest that the two measures may be (a) assessing relatively distinct forms of ego identity, or (b) that the ego-identity construct as measured by the process (exploration) and outcome (commitment) dimensions needs further theoretical examination.
