Abstract:
Inconclusive results of how weight-loss treatment (WLT) results are affected by participants' eating disorders and/or binge eating are partly due to the variation caused by the multitude of assessment instruments used. The objective of the present study was to evaluate the psychometric properties of a short DSM-IV-based assessment instrument designed to be used specifically in WLT settings, the Eating Disorders in Obesity (EDO) questionnaire. Participants were 97 patients seeking WLT at four surgical and one non-surgical clinics. Participants were assessed by the EDO and the Eating Disorder Examination (EDE) interview . The validity and reliability of the EDO was measured as concordance with the EDE, and test-retest agreement of the EDO, respectively. Validity as well as reliability was found to be good for both eating disorders diagnoses and binge eating as a distinct symptom. Results suggest that the EDO is a short, easily administered instrument with good psychometric properties which makes it a suitable, economical method of assessing eating disorders and binge eating in clinical WLT settings.
