Note. Partial eta squared (ηp2) values are considered small at .01, medium at .06, and large at .14 (Cohen, 1988). OBE, SBE, and OOE variables were square root-transformed to meet assumptions of normality. However, we report non-transformed means here to facilitate interpretation. BMI=Body Mass Index; OBE=Objective binge episode; SBE=Subjective binge episode; OOE=Objective overeating episode; EDE=Eating Disorder Examination; BDI=Beck Depression Inventory; BED=Binge eating disorder.
