Brief Summary

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

The primary objective of the STRIVE study is to compare two implementation strategies for Diabetes Prevention Program delivery: an in-person health coach strategy (standard 24 in-person sessions at WIC clinics) vs. a multifaceted technology-assisted health coach implementation strategy (12 in-person sessions at WIC clinics supplemented by technology support) on implementation and health-related outcomes in postpartum women.

Detailed Description

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

The overall objective of this project is to study the implementation, effectiveness, and sustainability of implementing the Diabetes Prevention Program (DPP) in postpartum women who receive services from WIC. In this effectiveness-implementation type III cluster-randomized trial, we will compare two implementation strategies for DPP delivery: an in-person health coach-led implementation strategy (standard 24 in-person sessions) vs. a multifaceted technology-assisted health coach implementation strategy (12 in-person sessions supplemented by technology tools).

Nineteen clinics will be randomized to the multifaceted technology-assisted health coach strategy and 19 to the in-person health coach-led strategy. A total of 722 postpartum participants (19 per clinic) will be recruited into the study and followed for 12 months for implementation and effectiveness outcomes. A post-intervention study visit will take place 6 months after the end of the 12-month intervention to evaluate the sustainability of the implementation strategies.

Blinding Strategy

NONE

Due to the nature of the cluster design and intervention program, the study participants, health coaches, DPP Coordinators, WIC clinic staff, and research staff who collect clinical outcome data will not be blinded.

Study Groups

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

In-person health coach strategy

Delivery of 24 health coaching sessions in-person by health coaches over 1 year.

Standard delivery of 24-sessions of the Group Lifestyle Balance (GLB) behavioral intervention in WIC clinics. The GLB was adapted from the original Lifestyle Balance behavioral intervention used in the original Diabetes Prevention Program trial for use in community translation and group settings. It focuses on improving diet and physical activity and promoting moderate weight loss through health coaching on behavioral change, including self-monitoring of food intake, physical activity, and weight.
