Brief Summary

Women, older adults, individuals from communities of color, particularly Black and Latino persons, and individuals with lower socioeconomic status are historically underrepresented in clinical research. This is true across a range of clinical areas but no more so than in Alzheimer's Disease Research. The purpose of this study is to assess whether offering small $25 financial incentives can increase enrollment of diverse community members to the Alzheimer's Prevention Trial (APT) Webstudy, a memory concerns registry meant to accelerate clinical trials, relative to non-monetary incentives such as a reusable grocery bag. To do this we will test in-person recruitment efforts at community events and locations, such as Northgate Gonzalez Market locations and local food bank events. We also aim to compare the relative cost of recruiting an additional person to the APT Webstudy.
