INTRODUCTION: Video-based cognitive testing is becoming more common. The 'VCog' study aims to evaluate the validity, feasibility, and acceptability of a standardized video-administered cognitive research battery.
METHODS: Twelve Alzheimer's Disease Research Centers (ADRCs) administered, in randomized order, an in-person and video-adapted Uniform Data Set Version 3 (UDSv3) cognitive assessment battery to participants with normal cognition (n = 156), mild cognitive impairment (MCI; n = 230), and dementia (n = 77). Acceptability of technology and participant experience completing video testing was assessed.
RESULTS: Of 463 participants (mean age 75.1 years, 52.5% female, and 25.5% non-White individuals), most rated video testing as easy (90.0%), convenient (95.3%) and would accept it in future visits (75.5%). Greater cognitive impairment was associated with more difficulty with setup and use of video. Staff rated most administrations as producing valid data (94.8%).
DISCUSSION: Video-based research cognitive testing with an adapted UDSv3 battery is feasible and well-accepted among older adults with and without cognitive impairment.
HIGHLIGHTS: The COVID-19 pandemic increased the need for video-administered cognitive assessments in Alzheimer's Disease Research Centers (ADRCs) . Feasibility, acceptability, and validity of video cognitive testing were evaluated. Participant experience and examiner evaluations of data validity were positive. Video assessment may extend the ADRCs reach to otherwise unreachable participants.
