Let's get aligned! Developing a core outcome set for clinical trials in eating disorders

Abstract

Objective

Our study aimed to review the outcome measures/assessment instruments used and to assess their heterogeneity/homogeneity in eating disorders (EDs) randomised controlled trials.

Methods

APA PsycInfo, PubMed, and Embase were searched in December 2022 to identify studies published between and inclusive of January 2012 and December 2022. Inclusion/exclusion criteria were: (1) complete articles published in peer-reviewed scientific journals, which were: (2) randomised trials, (3) in a clinical setting (4) with human subjects, (5) with an ICD or DSM diagnosis of Anorexia Nervosa, Binge Eating Disorder, or Bulimia Nervosa. The selected papers also: (6) used one or more standardised instruments designed to measure one or more psychometric characteristics associated with ED as a primary or secondary outcome, as judged by the authors of this systematic review, and (7) were published in English or Danish.

Results

Ninety one articles were included, and a total of 196 outcome measures were collected.

Discussion

The diversity of outcome measures in ED trials hampers result comparability and data integration. We suggest creating a core outcome measure set using the Delphi method, including clinician and patient-reported ED assessments, along with relevant comorbidity scales.
