Note: Models predicting global eating disorder psychopathology, as measured by the Eating Disorder Examination Global score and predicting frequency of objective binge eating in the past 28 days, as measured by the Eating Disorder Examination; Baseline refers to the baseline level of the outcome variable (EDE Global Score or Frequency of Binge Eating); GAS = Group Attitude Scale; GCQ-E – Group Climate Questionnaire – Short Form Engaged Subscale; Group 1 = Self-Help; Group 2 = Therapist Assisted; Group 3 = Therapist Led; GAS and GCQ-E were each centered.
