Question: You are a clinical psychologist who researches eating disorders. Dialectical Behavior Therapy (DBT) is a therapy that has recently been adapted for eating disorders, specifically binge eating disorder (BED). You are running a study to examine the outcome of DBT for 10 females diagnosed with BED who reside at an inpatient eating disorder facility. You administer the Eating Attitudes Test (EAT-26) to assess eating disorder symptoms (0-30; a score of 20 is very high). The inventory covers dieting, bulimia and food preoccupation, and oral control, which are important to know to determine patients’ recovery. You administer the EAT-26 at the beginning of treatment, at the end of treatment, and at 6 months follow-up.
