The National Institutes of Health Toolbox-Cognition Battery (NIHTB-CB) is a tablet-based cognitive assessment intended for individuals with neurological diseases of all ages. NIHTB-CB practice effects (PEs), however, need clarification if this measure is used to track longitudinal change. We explored the test-retest PEs on NIHTB-CB performance at 3 months in young healthy adults ( = 22). We examined corrected T-scores normalized for demographic factors and calculated PEs using Cohen's . There were significant PEs for all NIHTB-CB composite scores and on 4/7 subtests. This work suggests the need to further assess NIHTB-CB PEs as this may affect the interpretation of study results incorporating this battery.
美国国立卫生研究院工具包认知电池（NIHTB-CB）是一种基于平板电脑的认知评估工具，适用于各个年龄段患有神经疾病的个体。然而，如果该测试用于跟踪纵向变化，那么需要明确 NIHTB-CB 的练习效应（PE）。我们在 3 个月的时间内对年轻健康成年人（n=22）的 NIHTB-CB 进行了测试-重测 PE 研究。我们检查了经人口统计学因素校正后的 T 分数，并使用 Cohen's 计算了 PE。所有 NIHTB-CB 综合评分和 7 项测试中的 4 项均存在显著的 PE。这项工作表明，需要进一步评估 NIHTB-CB 的 PE，因为这可能会影响包含该测试的研究结果的解释。
