About

Two financial incentive strategies targeting adolescents with type 1 diabetes will be compared to usual care for motivating adolescents to engage in improved self-care to manage their diabetes.

Full description

Participants will be asked to choose a self-care goal relevant to the device(s) they use to manage their diabetes from a pre-defined list of self-care targets. A randomized 3 (treatment) x 3 (occasion) crossover design will be used to compare treatments that are administered to participants in a predetermined sequence. The intervention arms include financial incentives administered in a gain- and loss-frame for adherence to daily self-care goals. The control arm is usual care. Participants can also earn additional incentives for meeting clinical care goals such as an improvement in the percentage of time glucose levels are consistent with hyperglycemia (>180 mg/dL). The primary outcome will be HbA1c at 12 weeks compared to baseline. Secondary outcomes will include frequency of insulin administration, engagement in diabetes self-care (SCI-R), patient-reported outcomes (Problem Areas in Diabetes - Teen version and Diabetes Family Conflict Scale).

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Crossover Assignment

Masking: Double Blind

---

39 participants in 3 patient groups

Control

No Intervention group

Description:

Usual care reflects the standard treatment currently provided to T1D patients. 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. Telephone consultations are available 24/7 as often as necessary between clinic visits.

Gain-framed incentive

Experimental group

Description:

Participants will start off with nothing at the beginning of the treatment period. For each day that participants' meet goals, value will be added to their incentive balance. 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. Telephone consultations are available 24/7 as often as necessary between clinic visits.

Treatment:

Behavioral: Financial incentive (gain)

Loss-framed incentive

Experimental group

Description:

Participants will start off at the maximum incentive balance at the beginning of the treatment period and for each day that participants' fail to meet goals, value will be subtracted from their incentive balance over the 12-week. 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. Telephone consultations are available 24/7 as often as necessary between clinic visits.

Treatment:

Behavioral: Financial incentive (loss)
