Optimizing the unsupervised assessment of cognition in web‐based registries of individuals at risk for Alzheimer’s disease: Results from the Healthy Brain Project

Background Web‐based platforms are used increasingly to assess cognitive function in unsupervised settings. However, methods for ensuring the validity of cognitive data arising from unsupervised assessments are limited. We applied Human Computer Interaction (HCI) concepts of acceptability and usability to examine the validity of unsupervised cognitive testing in middle‐aged adults enrolled in the Healthy Brain Project (HBP). Method A total of...
