The purpose of this study was to examine the psychometric properties of the Diabetes Eating Problem Survey-Revised (DEPS-R) in a large sample of young patients with type 1 diabetes, to establish norms, and to validate it against the Eating Attitudes Test-12 (EAT-12).
A total of 770 children and adolescents aged 11-19 years with type 1 diabetes completed the DEPS-R and the EAT-12. In addition, age- and sex-standardized BMI and HbA1c data were obtained from the Norwegian Childhood Diabetes Registry. In addition to tests of validity, principal axis factoring was conducted to investigate the factor structure of the 16-item DEPS-R.
The DEPS-R demonstrated satisfactory Cronbach a (0.89) and was significantly correlated with the EAT-12 (0.65; P
