A - 74 Comparing HVLT-R Performance in Monolingual Vs. Spanish/English Bilingual Veterans

Abstract Objective Norms developed in monolingual populations may not be appropriate for use with bilingual patients. This study examined the impact of Spanish-English bilingualism on rote verbal memory using the Hopkins Verbal Learning Test-Revised (HVLT-R). Methods Clinically-referred veterans (86 monolingual; 30 bilingual) completed HVLT-R (English) during a comprehensive neuropsychological evaluation. Chi square analyses and independent samples t-tests were used to examine group demographic differences. Verbal fluency scores and HVLT-R scores were compared between groups using independent samples t-tests. Results Groups did not differ significantly in age (monolingual-M = 62.62; bilingual-M = 65.67) or education (monolingual-M = 13.9; bilingual-M = 13.2). Self-reported race/ethnicity was mostly White for the monolingual sample, while the bilingual sample was predominantly Hispanic. Groups also differed in gender composition (bilingual: 100% male; monolingual: 84% male). Groups did not differ in their speeded English phonemic word generation, t(108) = 0.311, p = 0.757, or speeded semantic word generation, t(109) = 1.931, p = 0.056, suggesting the current bilingual sample had high English proficiency. Cognitively unimpaired monolingual and bilingual veterans did not differ in their raw total recall, t(114) = 1.228, p = 0.222, delayed free recall, t(114) = 0.331, p = 0.741, percent retention, t(114) = 0.240, p = 0.811, or recognition discrimination, t(114) = 0.521, p = 0.603, for target words. Groups did not differ in their age-corrected T-scores in any of the above scores. Conclusions Results support the use of existing HVLT-R normative data for assessment of rote verbal memory in Spanish/English bilinguals with high English proficiency.
