The utility of the Spanish WAIS-III was investigated by examining its reliability and validity among 100 Spanish-speaking participants. Results indicated that the internal consistency of the subtests was satisfactory, but inadequate for Letter Number Sequencing. Criterion validity was adequate. Convergent and discriminant validity results were generally similar to the North American normative sample. Paired sample t-tests suggested that the WAIS-III may underestimate ability when compared to the criterion measures that were utilized to assess validity. This study provides support for the use of the Spanish WAIS-III in urban Hispanic populations, but also suggests that caution be used when administering specific subtests, due to the nature of the Latin America alphabet and potential test bias.
