Results of all analyses are adjusted for participant age, sex, and educational level.

ED, eating disorder; HC, Healthy Control; MD, mean difference; SD, standard deviation; η², Partial eta2; |d|, Cohen's d.

¹p-values are adjusted for multiple testing using the Holm–Bonferroni method.

^*Medium effect size for d > 0.50 and

^**large effect size for d > 0.80.
