This study, called InvesT1D, is looking at whether giving financial incentives (money) can help teenagers with type 1 diabetes better manage their condition. Participants will be between 12 and 18 years old and have had type 1 diabetes for at least a year. They also need to use a continuous glucose monitor (CGM) and either use it less than 70% of the time or give themselves insulin shots (boluses) less than 3 times a day on average. Some teens will receive financial rewards for reaching diabetes goals, while others will continue their usual care. The main goal is to see if these incentives improve their "Time In Range" (how long their blood sugar stays in a healthy range) over 12 to 18 months. Researchers will also look at how teens and their caregivers feel about their diabetes management.

Study design

This is an interventional study with 96 participants. Participants will be assigned to one of six groups, some receiving financial incentives and others continuing usual care.

What's involved

Participants will choose diabetes self-management goals, such as increasing daily insulin shots or CGM wear time. Researchers will collect data from participants and their caregivers.

Compensation

Participants in some groups will receive financial incentives (money) when they meet their selected goals.

Follow-up

Changes in glucose levels will be measured over 12 to 18 months.
