The main developmental task is identity development in adolescence period. Marcia defined four identity statuses based on exploration and commitment process: Achievement, moratorium, foreclosure and diffusion. Certain scales were developed to measure identity development. Another questionnaire that evaluates both four identity statuses and the exploration-commitment process separately is The Ego Identity Process Questionnaire (EIPQ). The most powerful feature of EIPQ is that it focuses on both identity status and exploration and commitment process. The aim of the current study is to adapt EIPQ into Turkish with factor structure, convergent validity and reliability studies on Turkish college students. This scale is consisted of 32-items. Sixteen of the EIPQ items assess exploration and 16 assess commitment. Current study analyzed data from 230 university students (120 female, 52.17%; 110 male, 47.83%). Exploratory and confirmatory factor analysis results showed that EIPQ has two factor-structures that function differently in identity development. Correlations of exploration and commitment with self-esteem, agency and depression scores were calculated in order to examine convergent validity. Internal consistency coefficients, test-retest values and item-total correlations indicated that EIPQ is a reliable scale. It can be concluded that "Turkish Version of EIPQ" can be used to evaluate both exploration and commitment processes and identity statuses.
