本研究的主要目的是建立广泛成就测试（WRAT-3）阅读评分在两次年度评估中的稳定性。参与者被分为对照组（n = 200），轻度认知障碍（MCI; n = 137），或可能或可能的阿尔茨海默病（AD; n = 41）。所有诊断组的重测稳定性均为可接受至较高水平。描述性分类（例如，“平均”）保持一致，只有74%的参与者。结果表明，WRAT-3阅读评分适用于老年人，尽管不支持使用分类描述符来描述基于这些评分的病前能力。
The primary goal of this study was to establish the stability of the Wide Range Achievement Test (WRAT-3) Reading score across two annual assessments of aging individuals. Participants were classified as controls (n = 200), mild cognitive impairment (MCI; n = 137), or possible or probable Alzheimer's disease (AD; n = 41). Test-retest stability was acceptable to high for all diagnostic groups. The descriptive classification (e.g., "average") remained consistent for only 74% of participants. Results indicated that WRAT-3 Reading scores are appropriate for use with older adults, though the use of categorical descriptors to describe premorbid ability based on these scores is not supported.
