Abstract

Aim:  Eating disorder screening tools have not been adequately validated for use with adolescents with type 1 diabetes. This study compared the Youth Eating Disorder Examination–Questionnaire (YEDE-Q) and the Eating Disorder Inventory-3 Risk Composite (EDI-3RC) against the child Eating Disorder Examination (chEDE). These screening tools were chosen because they broadly assess eating disorder psychopathology and have subscales helpful for clinical management.

Methods:  In this cross-sectional study, 124 adolescents with type 1 diabetes aged 13–18 years completed two self-administered questionnaires, the YEDE-Q and the EDI-3RC. Cronbach’s alpha was used to assess internal consistency of the tools. Fifty-one adolescents, randomly selected, participated in the chEDE. Intraclass correlations and Spearman’s correlations were used to measure concordance of the chEDE with the YEDE-Q and EDI-3RC.

Results:  The YEDE-Q and EDI-3RC demonstrated good subscale internal consistency; Cronbach’s alpha for YEDE-Q (0.78–0.95) and EDI-3RC (0.79–0.94). High levels of concurrent validity with the chEDE were seen with both tools.

Conclusion:  Preliminary evidence is provided for the validation of the YEDE-Q and EDI-3RC for use in adolescents with type 1 diabetes. The YEDE-Q also defines individual disturbed eating behaviours with frequency ratings which can be helpful for tailoring early intervention.
