Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Adolescent participants will be randomized to usual care or receive financial incentives for meeting diabetes self-management and clinical outcomes goals during the study. Researchers will compare changes in glucose levels, as well as adolescent and caregiver person-reported outcomes between groups.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The goal of this study is to find out whether financial incentives can help adolescents with their daily self-management. Adolescent participants will be assigned to one of 6 groups. Some participants will be asked to choose diabetes self-management goals such as increasing daily bolus insulin administration or increasing their continuous glucose monitoring system wear time, and then will be provided with financial incentives (money) when they meet their selected goals. Other participants will be asked to continue their diabetes management as usual.
Researchers will collect data from 96 adolescent participants and their caregivers to assess change in glucose levels, as well as adolescent and caregiver person-reported outcomes.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group A (low-value incentive, 6 months [24 weeks])
If the participant is assigned to Group A, they would receive $1.75 for each day that they meet their diabetes self-management goal. This equates to up to $49 every 4 weeks ($1.75 x 28 days = $49), or up to $294 over a period of 24 weeks. They would also receive $2.75 for each week that they meet their clinical outcome goal. This equates to up to $11 every 4 weeks ($2.75 x 4 weeks), or up to $66 over a period of 24 weeks. In total, they could earn up to $60 ($49 + $11) every 4 weeks, or up to $360 over a period of 24 weeks.
Financial Incentives Program
Adolescent participants will receive financial incentives for meeting diabetes self-management and clinical outcome goals.
Group B (high-value incentive, 6 months [24 weeks])
If the participant is assigned to Group B, they would receive $3.50 for each day that they meet their diabetes self-management goal. This equates to up to $98 every 4 weeks ($3.50 x 28 days = $98), or up to $588 over a period of 24 weeks. They would also receive $5.50 for each week that they meet their clinical outcome goal. This equates to up to $22 every 4 weeks ($5.50 x 4 weeks), or up to $132 over a period of 24 weeks. In total, they could earn up to $120 ($98 + $22) every 4 weeks, or up to $720 over a period of 24 weeks.
Financial Incentives Program
Adolescent participants will receive financial incentives for meeting diabetes self-management and clinical outcome goals.
Group C (low-value incentive, 12 months [48 weeks])
If the participant is assigned to Group C, they would receive $1.75 for each day that they meet their diabetes self-management goal. This equates to up to $49 every 4 weeks ($1.75 x 28 days = $49), or up to $588 over a period of 48 weeks. They would also receive $2.75 for each week that they meet their clinical outcome goal. This equates to up to $11 every 4 weeks ($2.75 x 4 weeks), or up to $132 over a period of 48 weeks. In total, they could earn up to $60 ($49 + $11) every 4 weeks, or up to $720 over a period of 48 weeks.
Financial Incentives Program
Adolescent participants will receive financial incentives for meeting diabetes self-management and clinical outcome goals.
Group D (high-value incentive, 12 months [48 weeks])
If the participant is assigned to Group C, they would receive $1.75 for each day that they meet their diabetes self-management goal. This equates to up to $49 every 4 weeks ($1.75 x 28 days = $49), or up to $588 over a period of 48 weeks. They would also receive $2.75 for each week that they meet their clinical outcome goal. This equates to up to $11 every 4 weeks ($2.75 x 4 weeks), or up to $132 over a period of 48 weeks. In total, they could earn up to $60 ($49 + $11) every 4 weeks, or up to $720 over a period of 48 weeks.
Financial Incentives Program
Adolescent participants will receive financial incentives for meeting diabetes self-management and clinical outcome goals.
Group E (usual care, 6 months [24 weeks])
Usual care reflects the standard treatment currently provided to adolescents with type 1 diabetes at Seattle Children's Hospital. All adolescent participants in the study will have access to the multidisciplinary care team including a diabetes provider, registered diabetes nurse, social worker, and nutritionist. They will continue to be offered routine diabetes clinic appointments as is the standard of care. Telephone consultations are available 24/7 as often as necessary between clinic visits.
No interventions assigned to this group
Group F (usual care, 12 months [48 weeks])
Usual care reflects the standard treatment currently provided to adolescents with type 1 diabetes at Seattle Children's Hospital. All adolescent participants in the study will have access to the multidisciplinary care team including a diabetes provider, registered diabetes nurse, social worker, and nutritionist. They will continue to be offered routine diabetes clinic appointments as is the standard of care. Telephone consultations are available 24/7 as often as necessary between clinic visits.
