A Cognitive Behavioral Therapy (CBT) Intervention to Reduce Fear of Hypoglycemia in Type 1 Diabetes

In persons with type 1 diabetes (T1DM), hypoglycemia is the major limiting factor in achieving optimal blood glycemic control. All persons with T1DM are at risk for hypoglycemia (blood glucose level < 70 mg/dl), which is life-threatening and accompanied by serious physical and psychological symptoms, resulting in a profound fear of hypoglycemia (FOH) and reduced quality of life. Young adults with T1DM are at greater risk for FOH and have worse glycemic control and self-management behavior than other age groups with T1DM. The investigator's preliminary research identified that 77% of young adults with T1DM reported FOH, and FOH resulted in increased glycemic variability. Glycemic variability (GV) is the minute-to-minute fluctuation in blood glucose that can be missed if looking only at A1C, a longer-term measure. Increased GV is dangerous because it is associated with cardiovascular events and diabetes complications. A major gap exists in how to manage FOH as a component of diabetes self-management. The Investigators specifically aim to: (1) determine the feasibility and acceptability of a fear reduction program in young adults with T1DM, who experience FOH; and (2) determine the impact of an 8-week cognitive behavioral therapy (CBT)-based intervention on the outcomes: FOH, self-management behavior, glycemic control, and GV. To achieve these aims, the investigators propose a randomized controlled trial in 50 young adults aged 18 to 35 years with T1DM. At completion, FOH will be measured and glycemic patterns will be analyzed to determine differences between the FREE and control groups. Findings from this proposed pilot study will serve as the foundation for a larger clinical trial to reduce FOH and improve self-management, glycemic control, and GV. This program of research promises to reduce the development of diabetes complications and improve quality of life for young adults with T1DM.
