Concurrent validity of self-report measures of eating disorders in adolescents with type 1 diabetes
Acta Pediatrica, 05/24/2012
D’Emden H et al. – Preliminary evidence is provided for the validation of the Youth Eating Disorder Examination–Questionnaire (YEDE–Q) and Eating Disorder Inventory–3 Risk Composite (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.
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.
- The YEDE-Q and EDI-3RC demonstrated good subscale internal consistency; Cronbach alpha’s 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.
