Abstract

Background: Sleep has been shown to be associated with treatment outcome in addictive disorders, mood disorders and mixed eating disorders samples. To date no research has examined the relationship between insomnia symptoms and treatment outcome in binge eating disorder (BED). Method: The present study was a secondary analysis that evaluated whether insomnia symptoms were associated with Dialectical Behaviour Therapy (DBT) self-help treatment outcome in a community sample of 71 participants with BED. Binge eating frequency, eating disorder psychopathology, insomnia symptoms, as well as anxious and depressive symptoms were assessed at pre- and post-treatment and at 3-month follow-up. Results: Results showed an improvement in insomnia symptoms from pre- to post-treatment and that baseline clinical levels of insomnia symptoms were associated with poorer treatment outcome at a trend level. Conclusion: Results are preliminary and additional research is needed to determine the prognostic significance of sleep in BED. Clinical implications and future directions are discussed.
