Validity and reliability of the Turkish version of the Eating Disorder Examination Questionnaire (EDE-Q-13): Short-Form of EDE-Q 

Abstract Background: The Eating Disorder Examination Questionnaire (EDE-Q) is a frequently used scale to evaluate eating behaviors and attitudes. In recent years, its use has increased due to the fact that the use of short forms is more practical. The aim of this study was to validate the short Turkish form of the Eating Disorder Examination Questionnaire (EDE-Q).Methods: The study included 924 adults at a mean age of 30.3±10.93 years. EDEQ-13 was translated and adapted to Turkish according to the Beaton guideline. The Eating Attitudes Test - 26 (EAT-26), Satisfaction with Life Scale (SWLS), and Body Appreciation Scale (BAS) were used to analyze their relationships with EDE-Q-13. Results: In this study, the rate of the total variance explained by the factors of EDE-Q-13 according to the Explanatory Factor Analysis (EFA) results of the scale was 83.545%. The Cronbach's alpha value of the scale was 0.897, and the Cronbach's alpha values of the 5 subscales were calculated in the range of 0.758-0.942. Criterion validity showed an acceptable correlation between the EAT-26, SWLS and BAS. Confirmatory factor analysis (CFA) revealed that the model obtained was within goodness-of-fit and acceptable -of-fit indexConclusion: Both EFA and CFA results showed that it is appropriate to use the Turkish EDE-Q-13. EDE-Q-13 was significantly correlated with eating disturbances, body appreciation, and life satisfaction. In conclusion, the Turkish version of EDE-Q-13 possesses high levels of validity and reliability.
