An essential step in designing effective strategies to improve patient engagement in behavior change is to better understand their current levels of engagement in these behaviors and determine which factors most influence their engagement. Within and outside the VHA, little is known about how patients with risk factors for T2DM view their risk of developing T2DM, what these patients understand about strategies to reduce this risk, and to what degree at-risk patients are currently engaging in behaviors to prevent T2DM. This project will generate important new data in these areas and will improve the investigators' understanding of the effects of a prediabetes diagnosis and brief counseling on engagement in behaviors to prevent T2DM and mediators of these behaviors.
