To investigate the responsiveness and predictive validity of the computerized digit vigilance test (C-DVT) in inpatients receiving rehabilitation following stroke. Forty-nine patients completed the C-DVT and the Barthel Index (BI) after admission to and before discharge from the rehabilitation ward. The standardized response mean (SRM) was used to examine the responsiveness of the C-DVT. We used a paired -test to determine the statistical significance of the changes in scores on the C-DVT. We estimated the predictive validity of the C-DVT with the Pearson correlation coefficient () to investigate the association between the scores of the C-DVT at admission and the scores of the BI at discharge. Our data showed a small SRM (-0.31) and a significant difference (paired -test, = 0.034) between the C-DVT scores at admission and discharge. These findings indicate that the C-DVT can appropriately detect changes in sustained attention. In addition, we found a moderate association ( = 0.48) between the scores of the C-DVT at admission and the scores of the BI at discharge, suggesting the sufficient predictive validity of the C-DVT. Our results showed that the C-DVT had adequate responsiveness and sufficient predictive validity in inpatients receiving rehabilitation following stroke. Implications for rehabilitation The computerized digit vigilance test (C-DVT) had adequate responsiveness to be an outcome measure for assessing the sustained attention in inpatients receiving rehabilitation after stroke. The C-DVT had sufficient predictive validity to predict daily function in inpatients receiving rehabilitation after stroke.
为了调查接受中风康复治疗的住院患者的计算机数字警觉测试（C-DVT）的反应性和预测效度。49 名患者在入住康复病房后和出院前完成了 C-DVT 和巴氏指数（BI）。使用标准化反应均值（SRM）来评估 C-DVT 的反应性。我们使用配对检验来确定 C-DVT 分数变化的统计学意义。我们使用 Pearson 相关系数（）来估计 C-DVT 的预测效度，以调查入院时 C-DVT 分数与出院时 BI 分数之间的关联。我们的数据显示 SRM 较小（-0.31），并且入院和出院时的 C-DVT 分数之间存在显著差异（配对检验，=0.034）。这些发现表明 C-DVT 可以适当检测到持续注意力的变化。此外，我们发现入院时的 C-DVT 分数与出院时的 BI 分数之间存在中度关联（=0.48），这表明 C-DVT 具有足够的预测效度。我们的结果表明，C-DVT 在接受中风康复治疗的住院患者中具有足够的反应性和足够的预测效度。对康复的影响计算机数字警觉测试（C-DVT）具有足够的反应性，可以作为评估中风后康复住院患者持续注意力的结果测量。C-DVT 具有足够的预测效度，可以预测中风后康复住院患者的日常功能。
