Trial results for a study investigating behavioral approaches to reducing diabetes distress and improving glycemic control in adults with Type 1 Diabetes were posted on ClinicalTrials.gov on 2025-10-14. The study enrolled 296 participants.
Background
Type 1 Diabetes is a chronic autoimmune condition requiring lifelong management of blood glucose levels through insulin therapy. Beyond the physiological challenges, many individuals with Type 1 Diabetes experience significant psychological burden, often referred to as diabetes distress. This distress encompasses worries and concerns related to managing the condition, fear of complications, and the constant demand for self-care. Addressing diabetes distress is crucial not only for mental well-being but also for improving adherence to treatment regimens and ultimately, glycemic control. Behavioral interventions offer a promising avenue to support patients in coping with the demands of living with Type 1 Diabetes.
Trial design
This completed study, designated as Phase NA, enrolled 296 adult participants diagnosed with Type 1 Diabetes and experiencing Diabetes Distress. The trial compared three distinct behavioral programs: TunedIn, FixIt, and StreamLine. The objective was to assess their effectiveness in reducing diabetes distress and improving glycemic control. Approximately one-third of participants were assigned to each program.
Key results
The trial reported several key measurements at 12 months across the three behavioral programs:
- Diabetes Distress at 12 Months (score on a scale):
- StreamLine: Mean score of 2.34 (Standard Error 0.074)
- TunedIn: Mean score of 2.03 (Standard Error 0.077)
- FixIt: Mean score of 2.06 (Standard Error 0.079)
- Hemoglobin A1c (HbA1c) at 12 Months (percentage of glycosylated hemoglobin):
- StreamLine: Mean of 7.52% (Standard Error 0.092)
- TunedIn: Mean of 7.60% (Standard Error 0.098)
- FixIt: Mean of 7.94% (Standard Error 0.101)
- Hypoglycemic Episodes at 12 Months (hypoglycemic episodes):
- StreamLine: Mean of 1.17 (Standard Deviation 1.15)
- TunedIn: Mean of 1.32 (Standard Deviation 1.66)
- FixIt: Mean of 1.23 (Standard Deviation 1.46)
- Depression Symptoms at 12 Months (score on a scale):
- StreamLine: Mean score of 6.35 (Standard Deviation 5.72)
- TunedIn: Mean score of 5.94 (Standard Deviation 4.54)
- FixIt: Mean score of 7.09 (Standard Deviation 5.73)
Several ANCOVA analyses were also performed, reporting various mean differences (final values) and p-values. These included mean differences of 0.28 (p-value 0.007), 0.42 (p-value 0.006), and 0.15 (p-value 0.82). Further analyses showed mean differences of 1.15 (p-value 0.01), 0.04 (p-value 0.4), and 1.65 (p-value 0.12).
What this means
The results suggest that behavioral programs can influence diabetes distress and glycemic control in adults with Type 1 Diabetes. Specifically, the TunedIn and FixIt programs were associated with lower mean diabetes distress scores compared to the StreamLine program at 12 months. Regarding glycemic control, the StreamLine program showed the lowest mean HbA1c, while FixIt had the highest. The reported statistical analyses indicate some significant differences in mean outcomes, which could point to varying effectiveness among the behavioral interventions. These findings highlight the potential for tailored behavioral support to improve both psychological well-being and clinical markers in individuals managing Type 1 Diabetes, though the specific comparative effectiveness of each program on all outcomes would require further detailed analysis.
