The state of research on ego identity: A review and appraisal : Part II.

In the first part of this review (see Volume 7, Number 3 of this journal), a comprehensive survey of empirical research on ego identity was presented. Special emphasis was given to the large number of studies employing James Marcia's "identity status" paradigm. Research within this paradigm is recapitulated here by presenting empirical results which typify each of the four identity statuses (i.e., achievement, moratorium, foreclosure, and diffusion). A detailed evaluation of the identity status paradigm itself follows. Among the topics considered are (1) the construct and external validity of the approach as a whole, (2) the rationale and discriminant validity of the identity statuses, and (3) the reliability of the Identity Status Interview. Part II concludes by considering a number of problems for future research. Several persisting methodological and substantive issues within the identity status paradigm are noted. Finally, it is suggested that investigators turn their attention to the processes mediating identity formation. Contemporary psychoanalytic conceptions of adolescent development are viewed as providing one possible theoretical framework for investigating such processes.
