37 The Influence of Informant Characteristics on Reports of Participant Functioning and Associations Between Reported Functioning and Neuropsychological Performance among Non-Hispanic Black Adults
Published online by Cambridge University Press: 21 December 2023
Abstract
Assessing one’s functional capacity
– in addition to neuropsychological performance
– is essential for determining neurocognitive status, and functional assessment is often provided via informant report. While informant characteristics have been shown to influence reports of participant functioning, the degree to which they moderate relationships between reported functioning and participant performance on neuropsychological testing is unclear. Moreover, associations among informant characteristics, reported functioning, and neuropsychological performance have not been directly examined with non-Hispanic Black (NHB) samples, despite this population’s disproportionately high risk for dementia.
In this cross-sectional observational study, we examined the influence of informant characteristics on (1) informant reports of participant functioning (assessed via the Functional Activity Questionnaire [FAQ]), and (2) associations between reported functioning and participant performance on neuropsychological testing, among NHB adult participants in the National Alzheimer’s Coordinating Center cohort (n=1024).
Younger age, female sex/gender, higher education, longer relationships with participants, and cohabitation were informant characteristics associated with poorer reported functioning (ps<.01). Moreover, poorer reported functioning was associated with poorer performance on (1) memory and language tests, particularly for participants with male (versus female) informants, and (2) the Multilingual Naming Test, particularly for participants with cohabitating (versus non-cohabitating) informants (ps<.01).
Within the context of neurocognitive evaluation of NHB adults, informant age, sex/gender, education, relationship length, and cohabitation status influence informant reports of participant functioning, and informant sex/gender and cohabitation status in turn moderate associations between reported functioning and participant performance on comprehensive neuropsychological testing.
