BACKGROUND: 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.
OBJECTIVES: To evaluate the feasibility, usability, and acceptability of TAS Test.
DESIGN AND SETTING: TAS Test was administered remotely at home and/or in a research facility, using personal computers.
PARTICIPANTS: 2,351 adults aged 50-89 years (mean 65.35), 71.76 % female, from Tasmania, Australia.
MEASUREMENTS: Completion rates, ease-of-use, distraction, test duration, and enjoyment scores. Demographics, computer literacy, cognition, and mood were analyzed.
RESULTS: 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.
CONCLUSIONS: 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.
