Background: Eating disorders are increasingly prevalent during adolescence, a critical developmental stage, and there is a pressing need for concise, yet robust assessment tools tailored for this age group. This study evaluated the psychometric properties of the Turkish version of the Eating Disorder Examination Questionnaire-13 (EDE-Q-13) among healthy adolescents. Methods: A total of 223 participants aged 10–17 years were recruited from Istanbul University-Cerrahpaşa, Faculty of Medicine. Internal consistency, test–retest reliability, and construct validity were examined through Cronbach’s alpha, McDonald’s omega, Composite Reliability (CR), Average Variance Extracted (AVE), confirmatory factor analysis (CFA), and correlations with the Eating Attitudes Test-26 (EAT-26) and the Body Appreciation Scale-2 (BAS-2). Results: The total scale showed high internal consistency (α = 0.86, ω = 0.85), with subscale reliabilities ranging from acceptable to good (α = 0.60–0.87). CFA supported the original five-factor structure, yielding satisfactory model fit indices (CMIN/df = 1.58, RMSEA = 0.05, CFI = 0.97, TLI = 0.97). Test–retest reliability over a 15-day interval demonstrated strong temporal stability (r = 0.82; ICC = 0.795–0.886). Significant positive correlations with EAT-26 and negative correlations with BAS-2 confirmed convergent and discriminant validity. Conclusions: These findings indicate that the Turkish EDE-Q-13 is a valid, reliable, and efficient measure for assessing eating disorder psychopathology in healthy adolescents. Its brevity enhances practicality for both clinical and epidemiological research, though future validation in clinical populations is recommended.
