The data was collected through a voluntary face-to-face survey. The questionnaire was included their general characteristics and the MEQ-18 and Eating Attitude Test-26 (EAT-26). Confirmatory factor analysis (CFA) was used to test the validity of the MEQ-18. Statistical analyzes were conducted using the R-Project program and IBM SPSS Statistics for Windows 26.0.Results: The overall content validity index was 0.93. A confirmatory factor analysis was conducted for the two sub-scales and reduced the abbreviated of MEQ to 18 items. The Cronbach’s alpha coefficient was 0.718 for the MEQ-18 total factor scores and Cronbach alpha values for awareness, and disinhibition were found to be 0,843 and 0,789, respectively. The minimum discrepancy per degree of freedom = 4.914 and the model generally fit well to the structure (RMSEA = 0.074, CFI = 0.934, SRMR = 0.079, TLI = 0.925, GFI = 0.968, AGFI = 0.959).Conclusions: The findings of study showed that the psychometric properties of the abbreviated MEQ adapted into Turkish were acceptable through construct and internal consistency reliability.Level of evidence: Level V, descriptive cross-sectional study.
