First, there is a lack of information reported by Grotevant and Adams (1984) about the ethnic or racial makeup of the norming sample for the EOM-EIS.
TABLE 1 Means and Standard Deviations for the Extended Version of the Objective Measure of Ego Identity Status (EOM-EIS) and the Differentiation of Self Inventory Scale/Subscale M SD EOM-EIS Identity Achievement 66.
Thus, the BRIAS racial identity subscales (Pre-Encounter, Encounter, Immersion/Emersion, and Internalization) were the independent variables in the prediction of each of the EOM-EIS scales (Achievement, Moratorium, Foreclosure, and Diffusion).
Alphas for the EOM-EIS in the present study were adequate: .
Thus, the four subscales of the VIAS (Conformity, Dissonance/Introspection, Immersion, and Awareness) served as the independent variables in the prediction of each of the EOM-EIS scales (Achievement, Moratorium, Foreclosure, and Diffusion).
The four subscales of the VIAS (Conformity, Dissonance/Introspection, Immersion, and Awareness) were entered together as the predictors in the equation for the EOM-EIS Achievement subscale and accounted for 13% of the variance in Achievement, F(1, 171) = 26.
Berzonsky correlated identity status scores from the EOM-EIS with the Identity Style Inve ntory scales and found compatibility between the identity status and identity style constructs.
Explained variance obtained using the EOM-EIS was subtracted from that obtained using the EIPQ.
The effectiveness of the formulae was tested by means of comparing (a) the relationship of continuous measures of status on the EIPQ to Identity Style Inventory style measures with (b) the relationship of continuous measures of status on the EOM-EIS with Identity Style Inventory style measures.
An achieved identity status was not yet accomplished by the respondents, as measured by the EOM-EIS.
In contrast, this work utilized the EOM-EIS with longitudinal data.
Eriksonian-based identity development instruments, principally Marcia's (1980) interview format and the EOM-EIS (Grotevant and Adams, 1984), do not examine intimacy or relationship issues during the identity achievement versus diffusion stage.
