MINDD 3: Prediabetes and Delay Discounting — MINDD  

PreDiabetes Clinical Trial

Official title: Delay Discounting as a Target for Self-Regulation in Prediabetes

Status Completed

Clinical Trial Summary

The proposed research will translate research on delay discounting to the prevention of Type 2 diabetes (T2D) in persons with prediabetes. In this study, the investigators will verify target engagement (DD) by examining if EFT improves DD under conditions shown to increase discounting of the future. Prediabetics will be randomized to receive EFT/ERT in a factorial design when experiencing simulated poverty/neutral conditions, respectively. The effects will be measured on DD. The investigators predict that poverty conditions will increase discounting of the future for ERT subjects, but those receiving EFT will show levels of DD similar to levels observed for participants in the wealth condition.

Clinical Trial Description

The prevention of Type 2 diabetes in an obese person with prediabetes requires developing a healthier lifestyle. The rational approach for someone with prediabetes would be to eat healthier, be more active, lose weight, and manage their comorbidities. However, preliminary research suggests that individuals with Type 2 diabetes discount the future and engage in behaviors that maximize current pleasure and short-term gain; thus, daily choices needed to improve future health are rare in this population. Delay discounting (DD) describes the choice of smaller immediate versus larger delayed rewards. This behavioral process is related to a wide variety of health choices, ranging from preventive health to behavioral and medical regimen adherence, including regimens used for Type 2 diabetes. The investigators believe that DD provides a target for one type of self-regulation that can improve a wide variety of health behaviors and medical adherence.

Research from our laboratories has shown that episodic future thinking (EFT), a form of prospection which reduces the bias towards immediate gratification, activates brain regions involved in planning and prospection such that future rewards have increased value and the extent of delay discounting is reduced. Cueing individuals to think about future events during inter-temporal decision-making reduces the rate of DD, eating in and outside of the laboratory, and smoking behavior. The overarching goal of this research is to use an experimental medicine approach to translate basic research on DD and EFT into clinical interventions to prevent the transition from prediabetes to a diagnosis of Type 2 diabetes. ;
