Reliability and validity of a parent-reported screening tool for disordered eating in children and young people with type 1 diabetes.

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 parental use. Eighty-nine 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 well-being. 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, well-being, 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).

PaRent InterventiOn to pRevent dIsordered eating in children with TYpe 1 diabetes (PRIORITY): Study protocol for a feasibility randomised controlled trial.

AIMS: Increasing evidence suggests that children and young people with type 1 diabetes (T1D) are at greater risk of disordered eating compared to children without T1D. Disordered eating in T1D has been linked to impaired wellbeing, increased health service use and early mortality. To address this problem, we will co-develop a psycho-education intervention for parents of children and young people with T1D, informed by the Information Motivation Behavioural Skills model. METHODS: The objective of this study is to assess the feasibility and acceptability of the intervention compared to a waitlist control group using a feasibility randomised controlled trial (RCT) design. We aim to recruit 70 parents of children and young people with T1D (11-14 years), 35 in each arm. Those assigned to the intervention will be invited to participate in two workshops of 2 h each. Parents will be asked to complete outcome measures regarding eating habits, diabetes management, as well as a questionnaire based on the Information Motivation Behavioural Skills model which provides a theoretical foundation for the intervention. These will be completed at baseline, 1- and 3-month post-intervention. Children and young people will be asked to complete questionnaires on their eating behaviours at the same time intervals. Parents randomised to receive the intervention will be invited to take part in interviews to feedback on the intervention and research protocol acceptability. CONCLUSION: It is anticipated that the psycho-education intervention aimed at parents will help prevent the development of disordered eating in children and young people with T1D and improve parental wellbeing. The results of this feasibility trial will determine whether this intervention approach is acceptable to families living with T1D, and whether a definitive RCT of intervention effectiveness is justified. Qualitative findings will be used to refine the intervention and study protocols. TRIAL REGISTRATION: This protocol has been registered with ClinicalTrials.gov [Identifier: NCT04741568].
