Spanish and English neuropsychological assessment scales: relationship to demographics, language, cognition, and independent function.
This study examined the relationship of the Spanish and English Neuropsychological Assessment Scales (SENAS) to demographic, cultural, and language fluency variables and to measures of cognition and independent functioning. Participants were 367 Hispanics and 160 Caucasians in the 60+ years age range, all living in the community. In Study 1, education and language use had strong influences on SENAS scores and largely explained ethnic group differences in mean scale scores. Age had weak effects on most scales except for verbal memory measures. Acculturation effects in Hispanics were largely accounted for by education and language use. Study 2 showed equivalent sensitivity of SENAS to cognitive and functional status in Hispanics and Caucasians. Results indicate that interpretation of SENAS scores must be informed by effects related to education and language fluency but provide evidence of equivalent validity in Hispanics and Caucasians with respect to concurrent measures of cognition and independent function.
