Results: Disordered eating attitudes and behaviors are common in females with type 1 diabetes (T1D) and negatively impact glycemic control and diabetes outcomes. The Diabetes Eating Problem Survey (DEPS) is a 28-item, self-report questionnaire developed to screen for eating problems in diabetes. Seventy-six youth with T1D (65% female) completed the DEPS. Mean (±SD) age was 14.9±0.9 years (range 13-16), T1D duration was 7.5±3.7 years, zBMI was 0.8±0.7, and A1C was 8.6±1.7%. We revised the original DEPS to create an updated, shorter 16-item measure (DEPS-R) for use in the current era of physiologic insulin replacement. The original DEPS and the DEPS-R have excellent internal consistency (Cronbach's alpha=0.83 and 0.87, respectively). The DEPS-R demonstrated external validity through comparison with other indicators of disordered eating behaviors (see table). DEPS-R score was significantly correlated with zBMI, A1C, blood glucose (BG) monitoring frequency, youth and parent report of diabetes-specific family conflict, and youth and parent-proxy report of youth quality of life (PedsQL). DEPS-R score was also correlated with a 3-item subscale of eating-related items from the DQOLY (r=.59, p<.0001). Youth with possible or probable clinician-determined insulin omission scored significantly higher on the DEPS-R than youth not omitting insulin (p=.02). The DEPS-R demonstrates excellent internal consistency and external validity. Its abbreviated length (<10 minutes to complete) increases its utility as a screening tool for disordered eating attitudes and behaviors in clinical diabetes care.
