Psychometric properties and factor structure of the Diabetes Eating Problem Survey Revised in Danish adolescents with type 1 diabetes
Authors' conclusion
This study supports the validity of DEPS-R as a screening tool for detecting the risk of disordered eating in adolescents with T1D but challenges the relevance of item 4. Future research is needed on updating the original DEPS-R, including a sensitivity analysis of DEPS-R in detecting the risk of serious eating disorder-related behaviour in T1D.

As reported in the abstract
Psychometric properties of DEPS-R
- Internal consistency (Cronbach α)
- 0.87
- Correlation with Youth Eating Disorder Examination Questionnaire (YEDE-Q) (p < 0.01)
- r = 0.83
- Correlation with HbA1c (p < 0.01)
- r = 0.35
- Correlation with zBMI (p < 0.01)
- r = 0.35
- Correlation with age (p < 0.05)
- r = 0.20
- Factor analysis: three-factor structure, variance explained
- 58%
