Visual construction and memory tasks are routinely used in neuropsychological assessment, but their subjective scoring criteria can negatively affect the reliability of these instruments. The current study examined the standard scoring criteria for the Figure Copy and Recall subtests of the RBANS and compared them to a modified set of scoring criteria in two samples. In both a large community dwelling sample of older adults and in a mixed clinical sample, the original scoring criteria consistently led to lower scores than the modified criteria. Inter-rater reliability was high for the modified scoring criteria, and no age effects were found with the modified scoring criteria. In both samples, the modified scoring criteria led to Figure Copy scores that more closely approximated other performances on the RBANS compared to the standard criteria, whereas both scoring systems led to plausible Figure Recall scores. Despite these results, the present study cannot identify one scoring criterion as the "better," but only points out the significant differences between them. Such differences can have important clinical implications, and practitioners and researchers who utilize the RBANS with patient samples should be cautious when interpreting low scores on Figure Copy and Recall if the standard criteria are used.
视觉构建和记忆任务在神经心理学评估中经常使用，但其主观评分标准可能会对这些工具的可靠性产生负面影响。本研究考察了RBANS的图形复制和回忆子测验的标准评分标准，并在两个样本中将其与一组修改后的评分标准进行了比较。在一个大型的社区老年人样本和一个混合临床样本中，原始评分标准的得分始终低于修改后的标准。修改后的评分标准的评分者间信度很高，且未发现修改后的评分标准存在年龄效应。在两个样本中，与标准标准相比，修改后的评分标准使图形复制得分更接近RBANS上的其他表现，而两种评分系统得出的图形回忆得分都合理。尽管有这些结果，本研究无法确定一种评分标准为“更好”的标准，而只是指出它们之间的显著差异。这种差异可能具有重要的临床意义，使用RBANS对患者样本进行评估的从业者和研究人员在使用标准标准解释图形复制和回忆的低分结果时应谨慎。
