Abstract
Abstract Background There is a high prevalence and complex overlap between type 1 diabetes (T1D) and disordered eating. However, screening for disordered eating in children and young people (CYP) with T1D is not routinely conducted, with reluctance reported by both professionals and parents. This study aimed to validate a parent‐reported version of a validated disordered eating screening tool for CYP with T1D (the Diabetes Eating Problems Survey‐Revised; DEPS‐R). Methods The existing DEPS‐R was adapted for parent use. 89 parents of CYP with T1D aged 11‐14 years completed the parent‐reported DEPS‐R and other questionnaires related to demographics, child eating behaviours and parental wellbeing. CYP of parents were invited to participate with 51 CYP completing the validated CYP‐reported DEPS‐R for comparison. Results The parent‐reported DEPS‐R demonstrated good internal consistency (Cronbach's α = 0.89). Moderate to good inter‐rater reliability was found between the parent‐reported DEPS‐R and CYP‐reported DEPS‐R (ICC 0.746, 95% CI = 0.554‐0.855, p <0.001), indicating good convergent validity. Construct validity with hypothesised variables, including specific eating behaviours, diabetes‐related distress, wellbeing, CYP BMI, gender and parental worry about CYP disordered eating, suggested validity of the measure. However, some hypothesised variables did not significantly correlate with the parent‐reported DEPS‐R as expected. Conclusions The parent‐reported DEPS‐R has demonstrated good reliability and validity and it may provide clinical benefit by increasing screening and early detection of disordered eating in CYP with T1D. Whilst novel and providing stepped increase in our knowledge, these findings would benefit from further validation (e.g., in a larger sample and responsiveness).
