Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is evaluating a behavioral treatment program that uses diabetes coaching and financial rewards in addition to continuous glucose monitoring to improve diabetes management in adult patients with type 2 diabetes. This study will evaluate if this behavioral treatment program increases individual adherence to a diabetes treatment plan and improves blood sugar management.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A randomized parallel-group pilot study of a combination intervention using Motivational Interviewing (MI) and Contingency Management (CM) for patients with T2DM. Individuals will be randomized in a 1:1 ratio to the intervention group or the control group. Randomization will be blocked and stratified by long-acting insulin and GLP1 medication use. All participants will be given a Continuous Glucose Monitor (CGM) to assess real-time blood sugar levels and establish CM rewards for those assigned to the treatment group.

Blinding Strategy

SINGLE

Caregivers
Because this is a behavioral intervention, participant blinding is not possible. Randomization will occur after baseline assessment and participants will be instructed to not tell their provider their assigned condition.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Behavioral Intervention with financial rewards and coaching

Individuals in the treatment group will receive financial rewards (contingency management) and diabetes coaching (motivational interviewing) in addition to wearing a continuous glucose monitor while receiving their usual diabetes treatment.

Group Type EXPERIMENTAL

Behavioral Intervention with financial rewards and coaching

Intervention Type BEHAVIORAL

Participants will receive variable financial incentives based on their engagement with the continuous glucose monitor and meeting diabetes treatment goals. In addition, they will participate in three motivational interviewing sessions focused on their diabetes management. Participants will continue to receive their diabetes treatment as usual.

Control

Individuals in the control group will not receive any interventions and will only wear a continuous glucose monitor while receiving their usual diabetes treatment.

Group Type ACTIVE_COMPARATOR

Control

Intervention Type BEHAVIORAL

Participants will only receive a continuous glucose monitor, which they may engage with as desired and no further intervention. Participants in the control group will continue to receive their diabetes treatment as usual.
