Informant sex/gender moderates associations between reported functioning and memory performance in Mexican American adults.

In neuropsychological evaluations, assessing cognitive functioning is often achieved using objective neuropsychological measures, whereas subjective informant reports are typically obtained to determine manifest daily functioning. Informant reports of participant functioning and their associations with objective participant performance on neuropsychological testing have been shown to vary based on informant characteristics. However, associations among informant characteristics, reported functioning, and neuropsychological performance have not been adequately examined with Mexican American or other Hispanic/Latino samples, despite these populations' disproportionately higher rates of dementia due to Alzheimer's disease and related disorders.
