Abstract

The COVID-19 pandemic highlighted the need to validate novel remote assessment platforms. The risk of selection bias complicates interpretation of data from all-remote validation studies; persons agreeing to participate may be inherently different than those who decline. We examined participation and retention rates in an uncompensated study of a new web-based platform for self-administered remote cognitive assessment, Mayo Test Drive (MTD): Test Development through Rapid Iteration, Validation and Expansion. We hypothesized that those who declined would be older and have less education than those who participated. 292 women ≥55 years (Mage = 66 years; 44% college education or above; 92% White) were invited to complete two MTD sessions approximately one week apart. Although only half agreed to participate (53%, 156 completed session 1), attrition rate was low (5%; 148 also completed session 2). There was no difference in age (t(288) = 0.62, p = 0.59) or education level (X2 (5, N = 291) = 3.44, p = 0.63) for those who did vs. did not participate. Future studies, using a larger, more diverse sample, should explore additional factors associated with participating in remote research to aid in creating an individualized user experience and targeted strategies to increase engagement.
