艾弗森通过在计算变化分数时考虑时间2分数的变异性，扩展了可靠的变化方法。然而，由于现有数据有限，对影响变化的变量的描述并不完整。目前的文件试图解决这些局限性，并澄清了评估可靠的change.Methodusing一年的测试重测数据的可重复电池的评估神经心理状态（RBANS）在老年人谁是认知完整或轻度阿尔茨海默氏病（AD），变化分数进行了计算，并提出了各种模型，一致或分歧从艾弗森。认知完整的个体倾向于表现出较少的变量分数，特别是在时间2，这导致了比AD患者更大的变化分数。当应用于独立样本时，观察到不同的变化模式：（1）使用完整数据的模型比使用AD数据的模型显示出更多的认知变化;（2）校正练习效应并使用完整数据的模型显示出最大的下降;（3）校正练习效应并使用AD数据的模型显示出最大的改善。在独立的情况下，下降/稳定/改善分类的模型，表现出最强的关联是那些使用完整的数据和不一致的使用实践effects.ConclusionsOverall，研究结果强调计算可靠的变化的复杂性，他们借给额外的艾弗森的原始限制的警告。然而，使用被归类为认知完整的个人的数据和对实践效果的校正似乎是有道理的。
ObjectiveIverson expanded on reliable change methodology by accounting for the variability in scores at Time 2 in the calculation of change scores. However, due to limitations in available data, an incomplete picture of variables affecting change was presented. The current paper sought to address some of these limitations and clarify the methodology for assessing reliable change.MethodUsing one-year test-retest data on the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) in older adults who were cognitively intact or had mild Alzheimer’s disease (AD), change scores were calculated, and various models, consistent with or divergent from Iverson, were presented.ResultsAcross the RBANS, individuals with intact cognition tended to show less variable scores, especially at Time 2, which resulted in larger change scores than those with AD. When applied to an independent sample, different patterns of change were observed, with: (1) models that used intact data showed more cognitive change than those using AD data; (2) the model that corrected for practice effects and used intact data showed the most decline; and (3) the model that corrected for practice effects and used AD data showed the most improvement. The models that showed the strongest association in classifying independent cases as decline/stable/improve were those that used intact data and were discordant on the use of practice effects.ConclusionsOverall, findings highlight the complexity of calculating reliable change, and they lend additional caution to Iverson’s original limitations. However, the use of data from individuals classified as cognitively intact and a correction for practice effects seems warranted.
