The goal of this randomized pilot clinical trial is to describe the feasibility of a couple-based lifestyle intervention and the study protocol in preparation for a future definitive randomized clinical trial. Participants include individuals at risk for type 2 diabetes and their romantic partners.~Prior to all study procedures, eligible participants will be required to complete an informed consent process and electronically sign a consent document. 12 eligible couples will be randomly assigned to either an individual lifestyle intervention (PreventT2) or a couple-based adaptation designed with input from a community advisory board (PreventT2 Together) (1:1). Both curricula have CDC approval for use in the National DPP and are delivered to small groups of participants over the course of 12 months.~Across conditions, participants will complete assessments before and after the year-long intervention, as well as monthly during the intervention. Data will be collected on: feasibility, background, health behaviors, physical and mental health, and relationship functioning.
