Adolescents diagnosed with Type 1 Diabetes Mellitus often exhibit reduced adherence to their medical regimen and poor glycemic control. A retrospective study examined longitudinal hemoglobin A1c (HgbA1c) outcomes for adolescent patients referred to the psychology service embedded within an endocrinology clinic. Three patient groups were examined: (1) Treatment: 59 adolescents referred who engaged in psychotherapy; (2) No Treatment: 40 adolescents referred yet failed to initiate psychotherapy; (3) Control: 58 adolescents not referred for treatment and matched on demographics to the two treatment groups. Over 1 year, the Treatment group had a sustained decrease in HgbA1c while the No Treatment and Control groups had an overall increase in HgbA1c. At study end, the Treatment group had HgbA1c values that were not significantly different from patients who were not considered in need of psychological treatment (Control). Adolescents that utilized the pediatric psychology service saw decreased HgbA1c values over time.
