NCT05280184

Brief Summary

Our objective is to test the feasibility, acceptability, and initial efficacy of using behavioral economics incentives (BEI) in a novel, semi-automated intervention to target daily insulin BOLUS scores in adolescents with suboptimal insulin use.

Outcome Measures

Primary Outcomes (2)

  • Change in Glycated Hemoglobin- HbA1c

    proxy measure of average glycemic levels

    change in week 0 outcome at week 13

  • Change in Daily Insulin Bolus Score

    valid, objective measure of insulin use in youth with type 1 diabetes; range 0-3, higher scores reflect greater adherence to mealtime insulin use

    change in week 0 outcome at week 13

Secondary Outcomes (1)

  • Change in Glucose Time in Range (70-180 mg/dL)

    change in week 0 outcome at week 13

Study Arms (2)

Coin2Dose

EXPERIMENTAL

BEI intervention that also combines automated text message reminders to dose for insulin; will test Contingent and Non-Contingent BEI

Behavioral: Coin2Dose

Standard Care Control

NO INTERVENTION

Standard care control group; will not receive automated text message reminders to dose for insulin nor BEI for daily BOLUS scores

Eligibility Criteria

Age11 Years - 17 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • adolescents between 11.0-17.0 years old and their parent/guardian;
  • adolescents have a physician confirmed diagnosis of type 1 diabetes of at least 6 months duration;
  • adolescents use an insulin pump for daily type 1 diabetes self-management;
  • adolescents evidence sub-optimal daily BOLUS scores (a mean daily BOLUS score \<2.5)

Limitations and Caveats

Between June 6 and July 24, 2024, a data attribution issue occurred that affected our ability to accurately link youth participants with their insulin pump data. Data from participants impacted by this issue are not included in the current dataset.
