Reliability and usability of an internet-based computerized cognitive testing battery in community-dwelling older people

Abstract

Cognitive decline is an early feature of neurodegenerative conditions. CogState has developed a game-like computerized test battery with demonstrated acceptability, validity, reliability, stability, efficiency and sensitivity to detecting cognitive decline in older people under supervised conditions. This study aimed to evaluate an internet-based version of this test when used remotely and self-administered in a cohort of healthy, community-dwelling older adults aged 55 and above over a 12 month period at 1-3 monthly intervals. Test usability and reliability was examined in terms of acceptability, stability and reliability. Of 150 participants (age: 63.6 ± 5.6, range 55-83 years), 143 (95%) ..
