Brief report: the Ego Identity Process Questionnaire: factor structure, reliability, and convergent validity in Dutch-speaking late adolescents.
The reliability and validity of a Dutch version of the Ego Identity Process Questionnaire (EIPQ) were evaluated. In Study 1, the instrument was found to exhibit a clear factor structure and acceptable reliability. Using Confirmatory Factor Analysis, both a model with two process factors (Commitment, Exploration) and a model with four content factors (Ideological Commitment, Ideological Exploration, Interpersonal Commitment, Interpersonal Exploration) evidenced a good fit once direction of wording was taken into account. In Study 2, moderate convergence was observed between Commitment and Exploration, and continuous measures of identity statuses and identity styles. The results of both studies combined indicated that the Dutch version of the EIPQ may be recommended as a research tool with college students.
