OBJECTIVE Prior research has focused on the normal frequency of obtaining low scores on a neuropsychological test battery, but few studies have examined the normal frequency of obtaining high scores. This study involved the preparation of high score multivariate base rates for the Spanish-language National Institutes of Health (NIH) Toolbox Cognition Battery (NIHTB-CB). METHOD Participants included 250 healthy Latinx adults (age range: 19-80) from the Spanish-language NIHTB-CB normative sample who completed the full battery (two crystallized and four fluid cognition tests). Multivariate base rates, stratified by education, crystallized ability, and sociocultural characteristics, quantified the frequency at which participants obtained one or more "high" fluid test scores (i.e., ≥50th, ≥63rd, ≥75th, ≥84th, ≥91st, ≥95th, and ≥ 98th percentile). RESULTS It was common for participants to obtain one or more high scores (i.e., 50.8% obtained one or more scores ≥84th percentile) and uncommon for participants to obtain "no" high scores, especially when using non-conventional thresholds for defining a high score (i.e., 10.8% obtained no scores ≥50th percentile). High scores were more commonly obtained by participants with greater education and higher crystallized ability, who were bilingual, born and educated within the United States, and from higher income households. CONCLUSIONS This study demonstrated that participants administered multiple neuropsychological tests commonly obtain high scores, and that the frequency of high scores varies by education, crystallized ability, and sociocultural characteristics. The absence of high scores may be indicative of cognitive impairment among examinees who are higher functioning, have greater education, and have specific sociocultural characteristics (e.g., bilingualism, higher socioeconomic status).

评估高功能西班牙语患者的认知衰退：西班牙语 NIH 工具箱认知电池的高分基本率。


目的 先前的研究主要集中在神经心理学测试组中获得低分的正常频率，但很少有研究考察获得高分的正常频率。这项研究涉及为西班牙语国家卫生研究院 (NIH) 工具箱认知电池 (NIHTB-CB) 准备高分多元基本率。方法 参与者包括来自西班牙语 NIHTB-CB 规范样本的 250 名健康拉丁裔成年人（年龄范围：19-80 岁），他们完成了全套认知测试（两项结晶认知测试和四项流体认知测试）。按教育程度、具体能力和社会文化特征分层的多变量基本率，量化了参与者获得一项或多项“高”液体测试分数的频率（即≥50、≥63、≥75、≥84、≥91、≥第 95 个百分位，且 ≥ 98 个百分位）。结果 参与者获得一项或多项高分的情况很常见（即 50.8% 的人获得一项或多项分数≥84%），而参与者获得“不”高分的情况并不常见，特别是在使用非常规阈值来定义高分时。分数（即 10.8% 的分数未达到 ≥ 50%）。受过高等教育、结晶能力较高、双语、在美国出生和接受教育、来自高收入家庭的参与者更容易获得高分。结论 这项研究表明，进行多项神经心理学测试的参与者通常会获得高分，并且高分的频率因教育程度、具体能力和社会文化特征而异。 缺乏高分可能表明功能较高、受过高等教育并具有特定社会文化特征（例如双语、较高社会经济地位）的考生存在认知障碍。
