Nearly half of adults in the United States have or are at risk of developing type 2 diabetes. The overall goal of this community-engaged research is to examine the efficacy of an innovative couple-based lifestyle intervention to prevent type 2 diabetes that is applicable to a broad range of partnered adults in the United States. By simultaneously targeting lifestyle and perceived support from romantic partners, there is a high likelihood of creating lasting changes in both
