常用於中風病人之工作記憶評估工具及其心理計量特性回顧

Working memory (WM) deficit is a common problem in patients with stroke, which has negative influences on the effectiveness of rehabilitation. Selecting and using WM tests with good psychometric properties and feasibilities is important to identify the WM problems. The objects of this study were to review and appraise both the psychometric properties (i.e., reliability, validity, and responsiveness) and feasibilities (i.e., materials of tests, assessment time, culture/language barriers of tests, and Chinese version) of WM tests that were frequently used (used at least 3 times) in empirical studies of stroke published from January 2009 to June 2014. The results of searching in the English and Chinese databases showed that six frequently used WM tests were the Digit Span Test, Spatial Span Test, Letter-Number Sequencing Test, Paced Auditory Serial Addition Test, Spatial Working Memory Test, and Trail Making Test-Part B. However, the pyschometric properties of the six WM tests were rarly examined except one study shown that the Letter-Number Sequencing Test had poor discriminative validity. Regarding to the feasibilities of the six tests, the Digit Span Test and Spatial Span Test had better feasibilities (i.e., short assessment time, no culture/language barriers, and acceptable Chinese version) to assess in domestic patients with stroke. This study found that the six frequently used WM tests had limited examinations of the psychometric properties in patients with stroke.
