Abstract Objectives Our aim was to evaluate self-reported depressive symptoms and clinical outcomes during routine screening for adolescents and young adults with type 2 diabetes (T2D), and examine associations among depressive symptoms and demographic and clinical characteristics. Methods The Patient Health Questionnaire (PHQ) was administered to 197 adolescents and young adults with T2D using the PHQ-2 or PHQ-9 in routine pediatric diabetes care at 4 academic medical centres. Data from electronic health records were extracted from the screening date and 12 months earlier. Results Adolescents and young adults with T2D (mean age, 16.85 years; 57% male; 77.2% non-Caucasian) completed the PHQ as part of routine diabetes care. On the PHQ, 19.3% of adolescents and young adults endorsed elevated depressive symptoms (PHQ score ≥10) and, among a subsample with item-level data (n=53), 18.9% endorsed thoughts of self-harm. Subsequently, 50.0% of those with depressive symptoms had a documented referral for mental health treatment in the electronic health record after the positive screening outcome. Older age, shorter diabetes duration, higher glycated hemoglobin level, being non-Hispanic white, more blood glucose checks per day and being prescribed oral medications were significantly associated with more depressive symptoms. Conclusions Screening for depressive symptoms identifies individuals in need of referral for mental health treatment. A focus on self-harm assessment, standardized methods for documentation of symptoms and mental health referrals and increased referral resources are needed.
