Feasibility of computerized motor, cognitive and speech tests in the home: Analysis of TAS Test in 2,300 older adults

Early detection of Alzheimer's disease (AD) risk is crucial for dementia prevention. Tasmanian Test (TAS Test) is a novel, unsupervised, computerized assessment of motor, cognitive, and speech function designed to detect AD risk.

To evaluate the feasibility, usability, and acceptability of TAS Test.

TAS Test was administered remotely at home and/or in a research facility, using personal computers.

2,351 adults aged 50-89 years (mean 65.35), 71.76 % female, from Tasmania, Australia.

Completion rates, ease-of-use, distraction, test duration, and enjoyment scores. Demographics, computer literacy, cognition, and mood were analyzed.

Over 80 % completed motor and cognitive components with 92.8 % completing speech tests. 89.81 % found the duration acceptable. 80.90 % of remote and 83.46 % of onsite participants enjoyed the procedure. High usability and acceptability were reported, with age, gender, education, computer literacy, cognition and mood having minimal or no impact.

TAS Test demonstrated high completion rates and user satisfaction across a large community sample, supporting its feasibility as an unsupervised computerized assessment tool. Future research should address demographic representation and technical refinements.
