: Motivation and Problem Solving vs. Mobile 360° Videos to Promote Enrollment in the National Diabetes Prevention Program’s Lifestyle Change Program among people with prediabetes: Randomized Trial Protocol
ABSTRACT
Background:
More than 88 million Americans are at risk of developing Type 2 diabetes mellitus (T2DM). The National Diabetes Prevention Program’s Lifestyle Change Program (DPP LCP) has been shown to be effective in reducing the risk of progressing from prediabetes to T2DM. However, most individuals who could benefit from the program do not enroll.
Objective:
The aim of this trial is to test the real-world efficacy of three Mobile phone-based approaches to increasing enrollment in the DPP LCP including a best practice condition and two novel approaches.
Methods:
We will conduct a three-armed randomized clinical trial comparing enrollment and one-month engagement in a DPP LCP among adults with prediabetes from two health care settings. Participants in the best practice condition will receive short message service (SMS) based notification that they have prediabetes, and a link to a website that explains prediabetes, T2DM, and the DPP LCP. This will be followed by a single question survey, “Would you like the DPP LCP to call you to enroll?” Participants in the two intervention arms will receive the same best practice intervention plus either two Mobile 360° Videos or up to 5 brief phone calls from a health coach trained in a motivational coaching approach known as Motivation and Problem Solving (MAPS). We will collect measures of: diabetes related knowledge, beliefs in the controllability of risk for T2DM, risk perceptions for T2DM, and self-efficacy for lifestyle change pre-intervention and 4 weeks later. The primary outcomes of the study are enrollment in the DPP LCP and 4-week engagement in the DPP LCP. In addition, data on the person-hours needed to deliver the interventions as well as participant feedback about the interventions and their acceptability will be collected. Our primary hypotheses are that the two novel interventions will lead to higher enrollment and engagement in the DPP LCP than the best practice intervention. Secondary hypotheses concern the mechanisms of action of the two intervention arms: 1) whether changes in risk perception are associated with program enrollment among participants in the Mobile 360° Video group? and 2) whether changes in self-efficacy for lifestyle change are associated with program enrollment among participants in the MAPS coaching group? Finally, exploratory analyses will examine the cost effectiveness and acceptability of the interventions.
Results:
The project was funded in September 2020, enrollment is beginning in February 2021 and is expected to continue through July 2022.
Conclusions:
We are conducting a test of two novel, scalable, Mobile phone-based interventions to increase enrollment in the DPP LCP. If effective, they have tremendous potential to be scaled up to help prevent Type 2 diabetes nationwide. Clinical Trial: ClinicalTrials.gov protocol ID: 00132307
