Developmental shifts during early adolescence relate to type 1 diabetes (T1D) self-management, increased risk of emotional distress, and worsening health status. Less is known about positive experiences related to T1D. This study evaluated associations of positive well-being (PWB) with diabetes burden, self-management, and glycemic control. Youth (N = 55, age = 12-13 years; X-bar age = 12.75 + 0.56 years, 50.9% male, 38.2% non-Caucasian) reported PWB, depressive symptoms, and diabetes burden. Parents reported on overall T1D adherence. Adherence behaviors and glycemic control were assessed objectively. Higher PWB correlated with lower depressive symptoms (r[subscript s] = -0.45), less diabetes burden (r[subscript s] = -0.48), and better glycemic control (r[subscript s] = -0.43), all p < 0.01. When controlling for diabetes duration, higher PWB correlated with lower depressive symptoms and better glycemic control. PWB was not related to demographics or adherence. Initial exploration suggests PWB is related to key diabetes constructs, and maybe valuable to consider along with efforts to support youth with T1D during a vulnerable developmental period.
