The Factor Structure and Psychometric Properties of the Greek Version of the Eating Disorders Examination Questionnaire (EDE-Q)

This study investigates the latent structure and the psychometric characteristics of the attitudinal subscales of the Greek translation of the EDE-Q (G-EDE-Q) using two samples. The first sample consisted of 500 university female students and tested the latent structure of the G-EDE-Q. The second sample consisted of 164 female psychology students and examined the internal consistency as well as the concurrent, convergent, and discriminant validity of the G-EDE-Q. The results from confirmatory factor analysis (CFA) showed that a three-factor solution fit the data better than the other models examined, providing evidence to contradict the originally proposed structure of the instrument. The results support both, the internal consistency as well as the concurrent, convergent, and discriminant validity of the G-EDE-Q global scale and its subscales. The discussion focuses on the critical review of previous statistical procedures employed and the clinical and research implications of the present findings.
