ED, eating disorder; AN, anorexia nervosa; BN, bulimia nervosa; BED, binge eating disorder; HC, healthy control; BMI, body mass index; DOI, duration of illness; EDFLIX-GF, general flexibility; EDFLIX-FoEx, food and exercise flexibility; EDFLIX-WeSh, weight and shape flexibility; BRIEF-A Shift, the Behavior Rating Inventory of Executive Function – Adult Version Shift subscale; EDDS SCS, Eating Disorder Diagnostic Scale Symptom Composite Score. Analyses of variance (ANOVA) are performed for group A, B, C, and D. For ED and HC total sample comparisons, see independent sample t-test in text. Results from post hoc Tukey tests have used p < 0.01 unless marked with an ∗p < 0.05. Cohen’s d effect sizes are reported in superscript brackets using the following denominations d = 0.2–0.5 (small), d = 0.5–0.8, (medium), d = ≥ 0.8 (large).
