Interventions

BEHAVIORAL

Individual intervention condition (PreventT2)

PreventT2 will be delivered by a team of trained CDC National Diabetes Prevention Program (NDPP) Lifestyle Coaches to adults at high risk for diabetes. The 2021 version of the lifestyle intervention curriculum to be used is freely available from the CDC. The intervention will be delivered in the context of the University of Utah National DPP, which has Full recognition from the CDC based on outcome data over the course of a number of years.

BEHAVIORAL

Couple-based intervention condition (PreventT2 Together; couple-based adaptation of 2021 PreventT2; approved by the CDC in November 2022 as an Alternate Curriculum for use in the NDPP)

PreventT2 Together will be delivered by a team of trained CDC National DPP Lifestyle Coaches to adults at high risk for diabetes and their partners. The lifestyle intervention curriculum was developed with the input of a community advisory board and was approved by the CDC for use in the National DPP (Diabetes Prevention Program) (i.e., meets CDC Diabetes Prevention Recognition Program Standards, including 22+ classes delivered over the course of 12 months and targeting lifestyle changes to prevent type 2 diabetes). In contrast to PreventT2, the intervention includes content specific to couples with prompts encouraging partners to consider and discuss how they can best support one another, information about lifestyle intervention in a relationship context, and examples demonstrating how couples collaborated to make healthy lifestyle changes.
