To examine two approaches to the measurement of identity, the identity dimension approach and the identity status approach, an identity dimension scale based on Bourne's theoretical analy sis (1978) was first constructed and validated. This scale was then administered together with an identity status scale constructed by Nato (1983) to 161 male and 135 female university students, and means of identity dimension score were compared among various identity statures. The identity achievement(A),

... eclosure(F), and achievement-foreclosure intermediate (A-F) statuses composed a homogeneous high mean dimension score subset; the moratorium(M) and diffusion moratorium intermediate (D-M) statuses composed a homogeneous medium mean score subset and the identity diffusion (D) status composed a low mean score subset, with identity dimension scores differing significantly among the subsets. The results suggested the validity and significance of the identity status approach.
