Abstract

Objective: To delineate score differences between the Wechsler Adult Intelligence Scale-IV (WAIS-IV) and the WAIS-IV México in the assessment of balanced bilingual Mexican Americans and to determine the efficacy of five hold measures in predicting summary scores in each version.

Methods: Hold measures were WAIS-IV Information, Vocabulary, and Matrix Reasoning subtests, picture vocabulary, and the Test of Premorbid Function (English)/Word Accentuation Test (Spanish). Using a repeated measures design, 60 neurologically intact participants were tested in a counterbalanced order, with WAIS-IV version as the repeated measure (mean intertest interval = 5.68 days). To minimize practice effects, the five visual-perceptual subtests, which contain the same items in each version, were administered only once during the initial session.

Results: All mean WAIS-IV México index/subtest scores were significantly higher than the U.S. equivalents (Full-Scale IQ by about .5 SD). Unexpectedly, most (83%) participants educated in the US to at least a high school level had numerically equal or higher scores on the U.S. version. Means on WAIS-IV language format indices/subtests were lower than those of visual-perceptual format indices/subtests within both versions (excepting Processing Speed Index/subtests in the U.S. version). All hold measures significantly predicted WAIS-IV summary scores for the U.S. version. Similarly for the México version, except for the Word Accentuation Test.

Conclusions: When evaluating a balanced bilingual Mexican American, opting for the WAIS-IV México version will yield higher scores across the Full-Scale IQ, indices, and all core subtests unless the patient was educated in the US to at least a high school level.

韦氏成人智力量表 - IV 墨西哥版与美国版在墨西哥裔美国人评估中的比较。
目的方法:保持测量包括WAIS-IV信息、词汇和矩阵推理子测试、图片词汇和病前功能测试(英语)/单词重音测试(西班牙语)。采用重复测量设计,60 名神经系统完好的参与者按照平衡顺序接受了测试,并以 WAIS-IV 版本作为重复测量(平均测试间隔 = 5.68 天)。为了最大限度地减少练习效应,五个视觉感知分测验在每个版本中都包含相同的项目,在首次测试中只进行一次:结果:所有 WAIS-IV 墨西哥指数/分测验的平均分都明显高于美国的同等水平(全量表 IQ 高出约 0.5 SD)。出乎意料的是,大多数(83%)在美国接受过至少高中教育的受试者在美国版本中的分数与之持平或更高。在两个版本中,WAIS-IV语言格式指数/小测验的平均值均低于视觉感知格式指数/小测验的平均值(美国版的处理速度指数/小测验除外)。在美国版中,所有保持测量都能明显预测 WAIS-IV 的总分。除了单词重音测试外,墨西哥版的情况与美国版类似:结论:在评估双语平衡的墨西哥裔美国人时,除非患者在美国至少接受过高中教育,否则选择 WAIS-IV 墨西哥版会在全量表智商、指数和所有核心分测验中获得更高的分数。

期刊介绍: The Journal of the International Neuropsychological Society is the official journal of the International Neuropsychological Society, an organization of over 4,500 international members from a variety of disciplines. The Journal of the International Neuropsychological Society welcomes original, creative, high quality research papers covering all areas of neuropsychology. The focus of articles may be primarily experimental, applied, or clinical. Contributions will broadly reflect the interest of all areas of neuropsychology, including but not limited to: development of cognitive processes, brain-behavior relationships, adult and pediatric neuropsychology, neurobehavioral syndromes (such as aphasia or apraxia), and the interfaces of neuropsychology with related areas such as behavioral neurology, neuropsychiatry, genetics, and cognitive neuroscience. Papers that utilize behavioral, neuroimaging, and electrophysiological measures are appropriate. To assure maximum flexibility and to promote diverse mechanisms of scholarly communication, the following formats are available in addition to a Regular Research Article: Brief Communication is a shorter research article; Rapid Communication is intended for "fast breaking" new work that does not yet justify a full length article and is placed on a fast review track; Case Report is a theoretically important and unique case study; Critical Review and Short Review are thoughtful considerations of topics of importance to neuropsychology and include meta-analyses; Dialogue provides a forum for publishing two distinct positions on controversial issues in a point-counterpoint format; Special Issue and Special Section consist of several articles linked thematically; Letter to the Editor responds to recent articles published in the Journal of the International Neuropsychological Society; and Book Review, which is considered but is no longer solicited.
