Abstract
In the last two decades, there has been a growing interest in short versions of questionnaires for measuring several psychological constructs. Focusing on identity development, in the present study, we extracted and tested the psychometric properties of the EIPQ-SF, a short version of the EIPQ scale for measuring identity according to Marcia’s identity statuses (achieved, foreclosed, moratorium and diffused identity). The data of our study derived from a sample of 210 college students aged 18-25 years. For extracting the EIPQ-SF, we first tested the content of the items of the original EIPQ and then we performed exploratory and confirmatory factor analyses. We evaluated the predictive validity of the EIPQ-SF by comparing the levels of self-esteem among participants with achieved, foreclosed, moratorium and diffused identity. The results of our study indicate that EIPQ-SF has a good factor structure and adequate validity and reliability; therefore, it can be used as a short scale for measuring identity in typical samples of young adults (university students). The advantages, applications as well as the limitations of the EIPQ-SF are thoroughly discussed.
