Note: Subscripts that differ represent differences between the subtypes using a Bonferroni-Hochberg post-hoc test. All LOC, OBE, and SBE episode means reflect the average number of episodes in the month prior to assessment. LOC = Loss of control eating; OBE = Objective binge episode; SBE = subjective binge episode; EE = Emotional eating; EAH = Eating in the absence of hunger; No-DE = No disinhibited eating; EDE = Eating Disorder Examination; BDI = Beck Depression Inventory; CDI = Children’s Depression Inventory; CBCL = Child Behavior Checklist (parent-reported psychopathology).
Effect sizes for analyses of variance are partial η2; effect sizes for chi-square tests are φ.
