Although the Spanish version of the WAIS (Escala de Inteligencia Wechsler para Adultos, EIWA) is widely used as a measure of intelligence in Spanish-speaking populations, little is known about the psychometric characteristics of the test beyond the information given in the test manual. Despite this, users have assumed that the test functions clinically and statistically as does the original WAIS. This assumption has been applied to the area of short test forms which are assumed to be as valid as those used with the WAIS. The present study is an attempt to determine the optimal two-, three-, four-, and five-test short forms for estimation of Full Scale IQ based on the EIWA standardization test data. In addition, the relative amount of common and specific variance in the EIWA subtests was determined, along with the degree of measurement error. The study emphasizes the limitations of using the EIWA arising from its out-of-date norms, use of a restricted Spanish-speaking population, and failure to make updates since its introduction. These cautions suggest that the EIWA (long and short forms) should not be used for determining IQs; instead its use should be limited to research and to tracking cognitive changes over time.
尽管韦氏成人智力量表西班牙语版（韦氏成人智力量表西班牙语版，EIWA）在说西班牙语的人群中被广泛用作智力测量工具，但除了测试手册中提供的信息外，对于该测试的心理测量学特征知之甚少。尽管如此，使用者一直认为该测试在临床和统计学上的功能与原始韦氏成人智力量表相同。这一假设已应用于短式测试领域，人们认为短式测试与用于韦氏成人智力量表的测试一样有效。本研究旨在根据EIWA标准化测试数据，确定用于估计全量表智商的最佳两测试、三测试、四测试和五测试短式。此外，还确定了EIWA子测试中共同方差和特定方差的相对量，以及测量误差程度。该研究强调了使用EIWA所存在的局限性，这些局限性源于其过时的常模、使用受限的西班牙语人群以及自引入以来未进行更新。这些注意事项表明，EIWA（长式和短式）不应被用于确定智商；相反，其使用应仅限于研究以及随时间跟踪认知变化。
