Effectiveness of Online Education for Recruitment to an Alzheimer's Disease Prevention Clinical Trial

For this study, 10,450 participants enrolled in an initial cohort study were asked to complete a six-lesson interactive education course, AlzU.org, about Alzheimer’s disease. Participants in the highest lesson completion group demonstrated the greatest screening rates for the Anti-Amyloid Treatment in Asymptomatic Alzheimer's Disease (A4) trial. In a subsequent randomized-controlled trial, 351 new participants were enrolled in the six-lesson course (n = 180) versus a time-neutral control course focused on Alzheimer’s disease information that would not be expected to change perceptions about Alzheimer’s clinical trials or other behaviors (n=171). After six months, 2.78% of the intervention group screened for the A4 trial compared to 0% of controls. The authors conclude that online education may serve as an effective strategy to supplement clinical trial recruitment.
