Self-administered computerized cognitive testing could effectively monitor older individuals at-risk for cognitive decline at home. In this study, we tested the feasibility and reliability of 3 tablet-based executive functioning measures and an executive composite score in a sample of 30 older adults (age 80±6) with high multimorbidity. The tests were examiner-administered at baseline and then self-administered by the participants at home across 2 subsequent days. Eight of the participants reported no prior experience with touchscreen technology. Twenty-seven participants completed both self-administered assessments, and 28 completed at least one. Cronbach's alpha (individual tests: .87-.89, composite: .93) and correlations between examiner-administered and self-administered performances (individual tests: .72-.91, composite: .93) were high. The participants who had never used a smartphone or a tablet computer showed comparable consistency. Remote self-administered tablet-based testing in older adults at-risk for cognitive decline is feasible and reliable, even among participants without prior technology experience.
