Learning processes and memory are frequently compromised in acquired brain injury (ABI), while at the same time such involvement is often heterogeneous and a source of deficits in other cognitive capacities and significant functional limitations. A good neuropsychological evaluation of memory is designed to study not only the type, intensity and nature of the problems, but also the way they manifest in daily life.
This study examines the correlation between a traditional memory test, the Wechsler Memory Scale-III (WMS-III), and a memory test that is considered to be functional, the Rivermead Behavioural Memory Test (RBMT), in a sample of 60 patients with ABI.
All the correlations that were observed were moderate. Greater correlations were found among the verbal memory subtests than among the visual memory tests. An important number of subjects with below-normal scalar scores on the WMS-III correctly performed (either fully or partially) the corresponding test in the RBMT.
The joint use of the WMS-III and RBMT in evaluation can provide a more comprehensive analysis of the memory deficits and their rehabilitation. The lower scores obtained in the WMS-III compared to those of the RBMT indicate greater sensitivity of the former. Nevertheless, further testing needs to be carried out in the future to compare the performance in the tests after the patients and those around them have subjectively assessed their functional limitations. This would make it possible to determine which of the two tests offers the best balance between sensitivity and specificity, as well as a higher predictive value.
学习过程和记忆在获得性脑损伤（ABI）中经常受到损害，与此同时，这种损害往往是异质性的，并且是其他认知能力缺陷和显著功能限制的一个来源。对记忆进行良好的神经心理学评估不仅旨在研究问题的类型、强度和性质，还旨在研究它们在日常生活中的表现方式。
本研究在60例ABI患者样本中，考察了传统记忆测试韦氏记忆量表第三版（WMS-III）与一种被认为具有功能性的记忆测试——里弗米德行为记忆测试（RBMT）之间的相关性。
观察到的所有相关性均为中等程度。言语记忆子测试之间的相关性高于视觉记忆测试之间的相关性。在WMS-III上标量分数低于正常水平的相当一部分受试者在RBMT中相应测试（全部或部分）表现正确。
在评估中联合使用WMS-III和RBMT可以对记忆缺陷及其康复进行更全面的分析。与RBMT相比，WMS-III获得的分数较低表明前者具有更高的敏感性。然而，未来需要进行进一步测试，以比较患者及其周围人主观评估其功能限制后测试中的表现。这将有可能确定这两种测试中哪一种在敏感性和特异性之间提供了最佳平衡，以及更高的预测价值。
