The relationship between emotion regulation difficulties and eating disorder outcomes: a longitudinal examination in a residential eating disorder treatment facility

Eating disorders (EDs) are associated with numerous comorbidities and deleterious outcomes (e.g. medical complications, high rates of death by suicide). The complexities of EDs are further compounded by treatment dropout, poor treatment outcomes, and relapse. One way to better understand these complexities is to investigate broad, transdiagnostic risk factors that contribute to the etiology and maintenance of EDs, such as emotion regulation (ER) difficulties. We longitudinally tested the relationship between ER difficulties and ED outcomes in a sample of 101 female ED patients in a southeastern U.S. residential ED treatment facility. Consistent with hypothesis, there were significant improvements in both ER difficulties and eating pathology from admission to discharge. Further, improvement in ER difficulties was associated with improvements in eating pathology. These findings further substantiate the role of ER difficulties in eating disorders and provide further evidence for the relationship between ER difficulties and eating pathology among residential eating disorder patients.
