    • Abstract:
      Background: Recent studies suggest that persons who suffer from eating disorders, specifically anorexia nervosa (AN) and bulimia nervosa (BN) have poor cognitive flexibility. Difficulties with cognitive flexibility and learning could be a critical part of the causes of eating disorders and may contribute to treatment resistance and relapse. This study aims to replicate previous findings of set-shifting deficits and examine how these deficits are related to treatment outcomes in a cognitive-behavioral treatment program. Method: A novel set-shifting task was given to 47 eating disorder patients presenting for intensive evidence-based outpatient treatment at a university clinic. Pre-treatment performance on the task was evaluated in relation to outcome three months after treatment. Pre-treatment set-shifting scores were also compared to scores of 17 healthy control (HC) participants. Clinical and personality traits were evaluated. Results: Patients diagnosed with AN had a statistically significant impairment in cognitive set-shifting compared to patients with BN and HC participants, but the BN group did not perform worse at the set-shifting task than HC group. There was little evidence that pre-treatment set-shifting scores were associated with clinical improvement during the course of treatment, but this hypothesis could not be adequately tested due the extremely high rate of missing data and attrition. Conclusion: This study replicates previous findings that patients with AN have set-shifting deficits compared to BN and HC. Future studies are needed to test the impact that pre-treatment cognitive flexibility may have on clinical improvement during treatment. (PsycINFO Database Record (c) 2019 APA, all rights reserved)
