A New Study Is Testing Whether Peer Support via Mobile App Can Help with Diabetes Distress

Living with type 1 diabetes involves constant decisions about insulin, food, activity, and blood sugar management. For many people, this ongoing responsibility creates emotional strain—a experience often called diabetes distress. It's different from clinical depression, but it's very real and affects quality of life.

Peer support—talking to someone who also has type 1 diabetes—can help. People who have lived the experience understand the challenges in ways others may not. Digital tools can make peer support more accessible, reaching people wherever they are.

REACHOUT is designed to be flexible and responsive. Participants can choose a peer supporter for one-on-one conversations, join a 24/7 chat room and discussion boards organized by topic, or attend small group video meetings. The app is customizable, meaning people can pick the support that fits their needs and preferences.

The idea behind 'just-in-time' support is important: when someone is struggling with their diabetes, they can reach out immediately rather than waiting for an appointment or scheduled call.

The trial enrolled 225 adults with type 1 diabetes between ages 19 and 81. Half of them (113 people) started using REACHOUT right away, while the other half (112 people) were put on a waitlist and eligible to join after six months. This design allows researchers to compare outcomes between those receiving the intervention and those not yet receiving it.

The main focus is diabetes distress, but researchers are also looking at depressive symptoms, feelings of social support, quality of life specific to diabetes, and resilience. They'll also measure blood sugar metrics (A1c and time in range), health care use, and cost-effectiveness to understand the full picture of how peer support affects people's lives.

REACHOUT is one of the first studies to rigorously test whether a peer-led mobile app can reduce the emotional burden of type 1 diabetes. The results could show whether this model is practical, effective, and worth the investment for health systems.

If peer support through an app works, it could expand access to mental health care for people with T1D—especially those in rural areas or with limited access to diabetes counselors and mental health professionals. The study is underway now, and results are expected to inform future mental health tools for the diabetes community.
