Evaluation of the usability of a brief computerized cognitive screening test in older people for epidemiological studies

Abstract

Background: Computerized cognitive testing has the potential to be an effective way to assess and monitor cognition in large neuroepidemiological studies. CogState is a game-like computerized test with demonstrated validity and reliability that has shown sensitivity to decline in older individuals over time. This study aimed to evaluate the serial usability of the test specifically within an older community cohort. Methods: The test battery was administered to healthy volunteers aged 50 years and above at 3-month intervals over 12 months in a community setting. Test usability was examined in terms of acceptability, efficiency and stability. Results: Of 301 subjects (age: 61.9 ± 7.2 years), 8..
