Objective: Eating disturbances are common in children placing a vulnerable group of them at risk for full-syndrome eating disorders and adverse health outcomes. In order to provide a valid self-report assessment of eating disorder psychopathology in children, a short form of the child version of the Eating Disorder Examination (ChEDE-Q) was psychometrically evaluated. Similar to the EDE-Q, the ChEDE-Q provides assessment of eating disorder psychopathology related to anorexia nervosa, bulimia nervosa, and binge-eating disorder. However, it does not assess symptoms of avoidant/restrictive food intake disorder, pica, or rumination disorder.
Method: In 1836 participants ages 7 to 18 years, recruited from two independent population-based samples, the factor structure of the recently established 8-item short form EDE-Q8 for adults was examined, including measurement invariance analyses on age, gender, and weight status derived from objectively measured weight and height. For convergent validity, the ChEDE-Q global score, Body Esteem Scale, Strengths and Difficulties Questionnaire, and sociodemographic characteristics were used. Item characteristics and age- and gender-specific norms were calculated.
Results: Confirmatory factor analysis revealed good model fit for the 8-item ChEDE-Q. Measurement invariance analyses indicated strict invariance for all analyzed subgroups. Convergent validity was provided through associations with well-established questionnaires and age, gender, and weight status, in expected directions.
Discussion: The newly developed ChEDE-Q8 proved to be a psychometrically sound and economical self-report assessment tool of eating disorder psychopathology in children. Further validation studies are needed, particularly concerning discriminant and predictive validity.
