The Turkish Version of the Munich Eating and Feeding Disorder Questionnaire: factor structure, validity, and reliability

Abstract

Objective: This research aims to examine the factor structure, validity, and reliability of the Munich Eating and Feeding Disorder Questionnaire (Munich ED-Quest) in Turkish, which is a new detailed self-rating scale developed for the assessment of eating and feeding disorders. Methods: The English version of the Munich ED-Quest was translated into Turkish using the back-translation technique. Five hundred thirty-four (461 females, 73 males) students studying at the Faculty of Health Sciences in a Turkish university whose age average was 23.0 +/- 3.0 years completed the Munich ED-Quest and the Eating Attitude Test (EAT). One hundred seventy-four of the participants completed the questionnaire again for the test-retest reliability within one week following the first conduct. Results: Factor analysis supported the three-factor structure of the Munich ED-Quest. The total Cronbach's alpha value was 0.940 (95% CI: 0.753-0.936 for the three subscales), and the test-retest reliability was 0.923 (95% CI: 0.755-0.906 for the three subscales) (all p<0.001) for the present time. The positive directional moderate correlation amongst the total points of Munich ED-Quest and EAT points supports the concurrent validity. Conclusion: This research reveals that the Turkish version of Munich ED-Quest is an acceptable, valid, and reliable scale for the investigation of eating disorders among the young Turkish population.
