DISORDERS
Trials 1 and 2 used the semi-structured Eating Disorder Diagnostic Interview (EDDI) to assess DSM-IV eating disorder symptoms (these trials started before DSM-5 but collected data used to approximate DSM-5 criteria). Diagnostic interviews were conducted in person at baseline and over follow-up, unless the participant moved from the area or was unable to complete in-person interviews, in which case they were completed by phone. Frequency of binge eating, vomiting, laxative/diuretic use, fasting, and excessive exercise, and overvaluation of weight/shape, feeling fat, and fear of weight gain were assessed monthly over the intervals between assessments. Participants who endorsed binge eating were asked about distress regarding binge eating, rapid eating, eating until uncomfortably full, eating large quantities of food when not hungry, eating alone because of embarrassment, feeling disgusted, depressed, or guilty after overeating. We used the monthly data on eating disorder symptoms to determine when participants first met criteria for threshold/subthreshold eating disorders (operationalized in Stice et al., Trial 3 used the Eating Disorders Examination (EDE) to assess DSM-5 diagnoses of eating disorders via phone. The EDE (Fairburn & Cooper, Diagnoses were conferred using the monthly symptom data collected in interviews. Diagnostic criteria for threshold and subthreshold eating disorders used in this study, which approximate but are not identical to DSM-5 criteria, are in Diagnostic criteria for threshold and subthreshold eating disordersBMI of between 90% and 85% of that expected for age and genderDefinite fear of weight gain more than 25% of the days for at least 3 monthsWeight and shape were definitely an aspect of self-evaluationMissed one period in a three month period (unless on birth control)BMI of less than 85% of that expected for age and genderDefinite fear of weight gain more than 50% of the days for at least 3 monthsWeight and shape one of the main aspects of self-evaluationMissing menstrual cycles in a three month period (unless on birth control)At least 2 uncontrollable binge eating episodes per month for at least 3 monthsAt least 2 compensatory behavior episodes (i.e. self-induced vomiting, laxatives use, diuretic use, fasting, and excessive exercise to compensate for overeating) per month for at least 3 monthsWeight and shape was definitely an aspect of self-evaluationAt least 8 uncontrollable binge eating episodes per month for at least 3 monthsAt least 8 compensatory behavior episodes per month for at least 3 monthsWeight and shape was definitely one of the main aspects of self-evaluationAt least 2 uncontrollable binge eating episodes/days per month for at least 6 monthsLess than 1 compensatory behaviors on average per month during this periodMarked distress about binge eatingBinge eating was characterized by 3 or more of the following: rapid eating, eating until uncomfortably full, eating large amounts when not physically hungry, eating alone because of embarrassment, feeling disgusted, depressed, or guilty after overeatingAt least 8 uncontrollable binge eating episodes/days per month for at least 6 monthsLess than 1 compensatory behaviors on average per month during this periodMarked distress about binge eatingBinge eating was characterized by 3 or more of the following; rapid eating, eating until uncomfortably full, eating large amounts when not physically hungry, eating alone because of embarrassment, feeling disgusted, depressed, or guilty after overeatingAt least 8 episodes of self-induced vomiting or diuretic/laxative use for weight control purposes per month for at least 3 monthsLess than 1 uncontrollable binge eating episode on average per month during this periodWeight and shape was definitely an aspect of self-evaluation
