| 目的 检验多维度视频定量评估系统（简称多维系统）在脑卒中手功能障碍患者中的信度和效度，为临床应用提供客观依据。 方法 对60例单手功能障碍的脑卒中患者，采用多维系统、手主动关节活动度（AROM-H）、Fugl-Meyer上肢功能评定量表（FMA-UE）、上肢运动研究量表（ARAT）进行评估。采取内部一致性、组合信度、分半信度、复本信度、评估者间信度、评估者内信度行信度检验，内容效度、结构效度、收敛效度、校标效度行效度检验。 结果 ①信度检验显示，多维系统Cronbach α系数=0.860，单维度的组合信度=0.939，分半信度系数=0.880，复本信度系数=0.922，各动作评估者间信度ICC=0.965～0.998［95%CI=（0.919，0.999）］，评估者内信度ICC值=0.973～0.998（95%CI=（0.937，0.999））。②效度检验显示，内容效度指数I-CVI=1，且各亚项与多维系统总分Pearson相关系数均＞0.600（P<0.01）；结构效度中KMO值=0.882（P<0.01），成分矩阵中存在一个公因子，累计反映原始变量60.879%的信息量；收敛效度AVE=0.609；标效度中多维系统与FMA-UE和ARAT的Pearson相关系数均＞0.700（P<0.01）。 结论 多维度视频定量评估系统对脑卒中手功能障碍患者的评估具有较高的信效度。 |

| Objective To test the reliability and validity of a multi-dimensional, quantitative video evaluation system (the Multi-dimensional system) for evaluating hand dysfunction among stroke survivors so as to provide an objective basis for its clinical application. Methods Sixty stroke survivors with single dysfunctional hand were evaluated using the Multi-dimensional system and also using the Fugl-Meyer Upper Extremity Assessment (FMA-UE) and the Action Research Arm Test (ARAT) and in terms of their active range of hand motion (AROM-H). The Multi-dimensional system′s internal consistency, composite reliability, split-half reliability, parallel-forms reliability as well as intra- and inter-observer reliability were quantified. Its validity was tested in terms of content validity, structural validity, convergent validity and criterion validity. Results The system′s Cronbach′s α was determined to be 0.86. Its one-dimension composite reliability was 0.939, its split-half reliability coefficient was 0.88 and its parallel-forms reliability was 0.922. The inter-evaluator reliability was between 0.965 and 0.998 ［95%CI= (0.919, 0.999)］, and the single evaluator ICC value was 0.973 to 0.998 ［95%CI= (0.937, 0.999)］. The validity test produced a content validity index of 1, and the Pearson correlation coefficients between each sub-item and the total score were all greater than 0.60. The KMO value for structural validity was 0.882, and there was a common factor in the component matrix which reflected 60.9% of the information in the original variables. The system′s convergent validity AVE was 0.609 with Pearson correlation coefficients between the multidimensional system and the FMA-UE and ARAT both > 0.70. Conclusion The multi-dimensional quantitative video evaluation system has good reliability and validity in the evaluation of stroke survivors with hand dysfunction. |
