Abstract

Emotion regulation (ER) difficulties are observed in eating disorders (EDs). However, few studies have explored ER before and after treatment. The aims are as follows: to explore ER difficulties across ED types and a healthy control (HC) group (Study 1) and to assess pretreatment and post-treatment changes among ED types (Study 2). In Study 1, adult women with EDs (n=438) and HC (n=126) completed an assessment including Eating Disorders Inventory-2, Difficulties in Emotion Regulation Scale and Symptom Checklist-90-Revised. Patients in Study 2 (n=69) were also reassessed after treatment. All ED types reported worse ER compared with HC (p<.001); also, ER differences were found between ED types. Prospective analyses show ER improvements after treatment (p<.001; |d|=0.51), especially in patients with bulimia nervosa (p<.001; |d|=1.03; Reliable Change Index=9.79) with greater improvement in those with a better treatment outcome (p=.034). In conclusion, emotion dysregulation is a part of all forms of EDs. Furthermore, emotional dysregulation can be modified. ED treatments for anorexia nervosa and binge eating disorder might be enhanced by targeting ER skills.
