Assessing Cultural Invariance of the Extended Objective Measure of Ego-Identity Status (EOM-EIS) Questionnaire

The purpose of this study was to assess the cultural invariance of the Extended Objective Measure of Ego-Identity Status (EOM-EIS) Questionnaire across three ethnic groups (African-Americans, Caucasians, and Latinos). The total sample consisted of 289 undergraduates from a comprehensive doctoral university in the Southeastern United States. Results of the chi-squared test of goodness-of-fit indicated that the sample reflected the university’s student body proportionally by gender, ethnicity, and academic major. To assess if the factor structure of the EOM-EIS operated equivalently across the three ethnic groups, a multi-group confirmatory factor analysis was conducted. Results indicated that EOM-EIS was invariant across the ethnic groups.
