Clinical Trial Summary

This single-blind, three-arm, randomized, controlled trial will assess the impact of messages and financial incentives on the enrollment of demographically diverse individuals to the Alzheimer Prevention Trials (APT) Webstudy. The APT Webstudy is a novel, online registry that employs quarterly cognitive testing using validated platforms. The APT Webstudy implements fully remote assessments, coordinated by the Alzheimer's Therapeutic Research Institute (ATRI) under USC IRB #HS-17-00746. The purpose of the current study is to test whether we can increase enrollment of diverse individuals into the registry. To do this, we will work with Contra Costa Regional Medical Center (CCRMC), the county public hospital and its affiliated health centers in Contra Costa County, California, to test whether sending messages with and without financial incentives to patients who receive primary care with the health system can increase enrollment to the APT Webstudy. The investigators hypothesize that 1) a certain small financial incentive and an award opportunity based incentive (or a drawing with a prize) will increase enrollment rates of CCHS members into the APT Webstudy relative to the control group. The investigators further hypothesize that the award opportunity incentive will increase the enrollment rate of CCRMC patients into the APT Webstudy more than a certain financial incentive with the same expected value.
