Study focus
The T1D REACHOUT study developed and piloted a mobile app aimed at reducing diabetes distress in adults with Type 1 Diabetes.
Diabetes distress is a significant issue for individuals with Type 1 Diabetes, impacting their mental health and diabetes management. Understanding whether mobile interventions can effectively reduce this distress is crucial for improving patient outcomes and enhancing support mechanisms in diabetes care.
Effectiveness of the intervention is unclear. Limited sample size may affect generalizability. Study design does not include a control group.
