This proposed Science of Behavior Change (SOBC) study will translate research on delay discounting to the prevention of Type 2 diabetes (T2D) in persons with prediabetes. A cross-sectional design will be used to test if delay discounting (DD) is a target related to behavioral and medical adherence in persons with prediabetes. Specifically, researchers will examine whether measures of DD, region of interest (ROI) neural activation during DD, and other executive functions are predictive of behavioral and medical adherence among prediabetics.
