OBJECTIVE reliable change methods can assist in the determination of whether observed changes in performance are meaningful. The current study sought to validate previously published 1-year standardized regression-based (SRB) equations for commonly administered neuropsychological measures that incorporated baseline performances, demographics, and 1-week practice effects. METHOD Duff et al.'s SRB prediction equations were applied to an independent sample of 70 community-dwelling older adults with either normal cognition or mild cognitive impairment, assessed at baseline, at 1 week, and at 1 year. RESULTS minimal improvements or declines were seen between observed baseline and observed 1-year follow-up scores, or between observed 1-year and predicted 1-year scores, on most measures. Relatedly, a high degree of predictive accuracy was observed between observed 1-year and predicted 1-year scores across cognitive measures in this repeated battery. CONCLUSIONS these results, which validate Duff et al.'s SRB equations, will permit clinicians and researchers to have more confidence when predicting cognitive performance on these measures over 1 year.

验证一年期可靠的变更方法

客观可靠的变革方法可以帮助确定观察到的绩效变化是否有意义。当前的研究试图验证先前发表的 1 年标准化回归 (SRB) 方程，用于常用的神经心理学测量，其中纳入了基线表现、人口统计数据和 1 周练习效果。方法 Duff 等人的 SRB 预测方程应用于 70 名社区居住的老年人的独立样本，这些老年人要么有正常认知功能，要么有轻度认知障碍，并在基线、1 周和 1 年进行评估。结果 在大多数指标上，观察到的基线和观察到的 1 年随访分数之间，或观察到的 1 年分数和预测的 1 年分数之间，观察到的改善或下降很小。与此相关的是，在重复的一组认知测量中，观察到的 1 年分数与预测的 1 年分数之间具有高度的预测准确性。结论 这些结果验证了 Duff 等人的 SRB 方程，使临床医生和研究人员在预测一年内这些措施的认知表现时更有信心。
