Anxiety, Obsessive-Compulsive, and Depressive Symptom Presentation and Change Throughout Routine Eating Disorder Treatment.

OBJECTIVE: The present study examined whether patients with binge/purge and restricting anorexia nervosa (AN-BP and AN-R), bulimia nervosa (BN), binge eating disorder (BED), avoidant/restrictive food intake disorder (ARFID), and other specified feeding and eating disorder (OSFED) differ in generalised anxiety disorder (GAD), obsessive-compulsive disorder (OCD), and depression symptom patterns and overall comorbid symptom severity at admission. We also assessed between-group differences in the patterns of change and overall comorbid symptom severity change from admission to discharge from routine eating disorder (ED) treatment at higher levels of care (HLOC). METHOD: The initial sample included 3730 adults routinely assessed for GAD, depression, and OCD at admission and discharge from treatment. RESULTS AND CONCLUSIONS: ED diagnostic groups exhibited somewhat different symptom patterns (e.g., AN-R and ARFID were more prone to GAD and OCD than depression symptoms; BED exhibited the opposite pattern) and overall symptom severity at admission (i.e., AN-BP and OSFED had the highest overall comorbid symptom severity; BED had the lowest). Although the overall symptom improvement was significantly greater in ARFID and BED than in AN-BP, AN-R, and OSFED, ED patients collectively and within each diagnostic group improved significantly in GAD, OCD, and depression symptoms following routine ED treatment at HLOC.
