Rising to the Challenge: Reliability Verification of an Asynchronous Remote Assessment for Cognitive Impairment
ABSTRACT
Background:
Evidenced by the further reduced access to testing during the COVID-19 pandemic, there is an urgent, ever-growing need for remote cognitive assessment for individuals with cognitive impairment. The Neurotrack Cognitive Battery (NCB), our response to this need, was evaluated for its temporal reliability and stability as part of initial validation testing.
Objective:
To assess the temporal reliability of the NCB tests across a one-week period and to determine the temporal stability of these measures across three consecutive administrations in a single day.
Methods:
For test-retest reliability, 29-66 cognitively healthy participants completed each cognitive assessment twice, one week apart. In a separate study, temporal stability was assessed using data collected from 31 different cognitively healthy participants at 3 consecutive timepoints in a single day.
Results:
Correlations for the assessments were between .72-.83, exceeding the standard acceptable threshold of .70 for temporal reliability. Intraclass correlations ranged from .60-.84, indicating moderate to good temporal stability.
Conclusions:
These results demonstrate the clinical utility of NCB as a brief, easy to administer, and reliable assessment for remote cognitive testing.
