This investigation provides internal consistency reliabilities for the Wechsler Memory Scale–Fourth Edition (WMS–IV) subtest and index discrepancy scores using the standardization samples of the Adult and Older Adult batteries. Subtest reliabilities ranged from .00 to .93 for Adults and .25 to .94 for Older Adults. Three of 91 Adult coefficients and three of 24 Older Adult coefficients reached the recommended level (≥ .90). Index reliabilities ranged from .46 to .94 for 100 Adult Battery comparisons and .19 to 93 for 36 Older Adult Battery comparisons. Each battery had 10 coefficients ≥ .90. Ability–memory discrepancies were reported using WAIS–IV VCI, PRI, WMI, and GAI as intelligence standards. Ability–memory comparisons for the Adult Battery ranged from .82 to .93 with 12 of 20 comparisons ≥ .90; Older Adult Battery reliabilities ranged from .85 to .94 with six of 16 comparisons ≥ .90. In terms of discrepancy score reliabilities, the WMS–IV represents a marked improvement over the WMS–III.

这项调查使用成人和老年人电池的标准化样本，提供了Wechsler记忆量表-第四版（WMS-IV）子测验和索引差异分数的内部一致性可靠性。成人的子测验信度范围为.00至.93，而老年人则为.25至.94。91个成人系数中的三个系数和24个老年人系数中的三个系数达到建议水平（≥.90）。100次成人电池比较的索引可靠性范围为.46至.94，而36位老年人电池比较的索引可靠性范围为.19至93。每个电池的10个系数≥.90。使用WAIS-IV VCI，PRI，WMI和GAI作为智能标准报告了能力-内存差异。成人电池的能力-记忆比较范围为.82至.93，其中20个比较中的12个≥.90；成年人的电池可靠性范围为。85至.94，其中16个比较中的六个≥.90。就差异评分的可靠性而言，WMS-IV较WMS-III有了显着提高。
