Given the disproportionate impact of neurologic disorders such as HIV on racial/ethnic minorities, neuropsychologists are increasingly evaluating individuals of diverse linguistic backgrounds. This study compares the utility of two brief and one comprehensive language measure to account for variation in English neuropsychological performance within a bilingual population.
Sixty-two HIV+ English/Spanish bilingual Latino adults completed three language measures in English and Spanish: Self-Reported Language Ability; Verbal Fluency (FAS/PMR); and the Woodcock Munoz Language Survey-Revised (WMLS-R). All participants also completed an English language neuropsychological (NP) battery.
It was hypothesized that the comprehensive English/Spanish WMLS-R language dominance index (LDI) would be significantly correlated with NP performance, as well as the best predictor of NP performance over and above the two brief language measures. Contrary to our hypothesis, the WMLS-R LDI was not significantly correlated to NP performance, whereas the easily administered Verbal Fluency and Self-Report LDIs were each correlated with global NP performance and multiple NP domains. After accounting for Verbal Fluency and Self-Report LDI in a multivariate regression predicting NP performance, the WMLS-R LDI did not provide a unique contribution to the model.
These findings suggest that the more comprehensive WMLS-R does not improve understanding of the effects of language on NP performance in an HIV+ bilingual Latino population.
鉴于诸如人类免疫缺陷病毒(HIV)等神经系统疾病对少数种族/族裔群体的影响不均衡,神经心理学家越来越多地对具有不同语言背景的个体进行评估。本研究比较了两种简短语言测量方法和一种综合语言测量方法在解释双语人群英语神经心理学表现差异方面的效用。
62名感染HIV的英语/西班牙语双语拉丁裔成年人用英语和西班牙语完成了三项语言测量:自我报告语言能力;言语流畅性(FAS/PMR);以及伍德库克-穆尼兹语言量表修订版(WMLS-R)。所有参与者还完成了一项英语语言神经心理学测试组合。
研究假设综合英语/西班牙语的WMLS-R语言优势指数(LDI)将与神经心理学表现显著相关,并且是在两种简短语言测量方法之外神经心理学表现的最佳预测指标。与我们的假设相反,WMLS-R LDI与神经心理学表现没有显著相关性,而易于实施的言语流畅性和自我报告LDI均与整体神经心理学表现和多个神经心理学领域相关。在预测神经心理学表现的多元回归中考虑言语流畅性和自我报告LDI后,WMLS-R LDI对模型没有独特贡献。
这些发现表明,更全面的WMLS-R并不能增进对语言对感染HIV的双语拉丁裔人群神经心理学表现影响的理解。
