Abstract
Objective
A valid estimate of premorbid ability (PA) is important when attempting to identify cognitive decline. Measures of PA in English have been widely validated, but there is a lack of PA instruments for Spanish speakers. The findings of a pilot study assessing the feasibility of using the Word Accentuation Test (WAT) as a PA measure in a diverse, traditionally underserved, Spanish speaking population are described.
Method
The WAT was administered as part of comprehensive neuropsychological evaluations and neurobehavioral status exams (NBSE) completed with Spanish speaking patients at Montefiore Medical Center (MMC) in a 6-month period. Sixty-one patients completed the WAT- 12 as part of comprehensive testing (mean age 60 (SD 11.05) range 43-80, 67% female) and 49 during NBSEs within the context of multidisciplinary memory disorders clinics (mean age 74.35 (SD 8.60) range 51-93, 80% female). T-tests and correlations with WAT performances were completed.
Results
Overall, our population correctly read an average of 19.67 (SD 7.61) words. There was no statistical difference by gender or age, but years of education predicted WAT performance (p = .004). For those individuals who had comprehensive cognitive evaluations, WAT scores were correlated with performance on the vocabulary subtest of the EIWA-III (p = .003). All patients without severe dementia were able to complete the task.
Conclusions
Analysis of pilot data from our diverse Spanish population demonstrated that the WAT is an PA appropriate task that appears to have good correlation with years of education and vocabulary performance. Additional research is necessary to validate the measure in this cohort and other cohorts.
