Validation of the Turkish Version of the Eating Attitudes Test-7

Abstract

Background: Disordered eating attitudes are major public health concerns associated with adverse physical, psychological, and social outcomes. Therefore, brief, psychometrically sound screening tools are needed to identify individuals at risk early. The Eating Attitudes Test-7 (EAT-7) is a shortened screening tool developed to assess disordered eating attitudes. However, its Turkish validity and reliability have not been previously examined. Therefore, this study aimed to assess the validity and reliability of the Turkish version of the EAT-7 among Turkish-speaking adults. Methods: This methodological validation study was conducted between November 2025 and January 2026. Data were collected online using a snowball sampling technique. After a pilot study with 210 participants, the main study included 1635 adults aged >= 18 years. Exploratory factor analysis was performed with 500 participants, and confirmatory factor analysis was performed with an independent sample of 1135 participants. Internal consistency and construct validity were assessed. Convergent validity was evaluated through correlations with the EAT-26, Eating Disorder Examination Questionnaire-13 (EDE-Q-13), and Depression Anxiety Stress Scale Short Form (DASS-8). Results: The Turkish version of the EAT-7 demonstrated excellent internal consistency, with a Cronbach's alpha coefficient of 0.925. The Kaiser-Meyer-Olkin value was 0.909, and Bartlett's test results were significant. Exploratory factor analysis supported a single-factor structure explaining 70.133% of the total variance. Confirmatory factor analysis confirmed a good model fit. The total EAT-7 score was positively correlated with the EAT-26, EDE-Q-13, and DASS-8 scores. Conclusions: The Turkish version of the EAT-7 is a valid, reliable, brief, and practical screening tool for assessing disordered eating attitudes among Turkish-speaking adults.
