摘　　要：目的:探讨Berg平衡量表在脑卒中患者中的构想效度。方法:40例符合入选标准的脑卒中偏瘫患者参与本研究。对患者进行Berg平衡量表、Fugl-Meyer评价表、步行速度和Barthel指数的评价。对测量数据进行项目分析、因素分析和相关性分析,验证Berg平衡量表的因素效度、会聚效度和区分效度。结果:经过因素分析形成包含两个因素,第一个因素测量与静态平衡相关的内容,第二个因素测量与动态平衡相关的内容,两个因素可解释总变异量为70.6%,显示Berg平衡量表具有良好的因素效度。Berg平衡量表得分显著相关于步行速度(rho=0.717,P<0.001)和Barthel指数得分(rho=0.673,P<0.001),显示Berg平衡量表具有良好的会聚效度。Berg平衡量表与Fugl-Meyer量表下肢得分之间显著相关(rho=0.655,P<0.001),而且Fugl-Meyer量表下肢得分≤25分组和得分>25分组的BBS得分之间比较差异显著(t=2.85,P=0.007),显示Berg平衡量表具有良好的区分效度。结论:Berg平衡量表在脑卒中患者中具有良好的构想效度。Objective：To examine the construct validity of Berg Balance Scale （BBS） in patients with stroke. Method： Forty ambulatory patients with stroke participated in this study. Each participant performed the assessment of BBS, Fugl-Meyer Scale,maximum walking speed and Barthel Index on the same day. Construct validity was investigated by using a factor analysis （factorial validity）. Result： The confirmatory factor analysis suggested a two- factor structure. Two factors were accounted for 70.6% of the variance. The first factor measured static-related problems and the second factor measured dynamic-related problems. The measurements indicated a good factorial validity for BBS. The scores of BBS closely correlated with maximum walking speed and Barthel index （rho=0.717 and 0.673, respectively P〈0.001）, and indicated a high level of convergent validity for BBS. The lower limb section at Fugl-Meyer scale assessment had positive correlation with scores of BBS （rho=0.655, P〈0.001） and Fugl-Meyer scores〉25 group achieved a significantly higher scores of BBS than Fugl-Meyer scores≤25 group （t=2.85, P=-0.007）. It indicated a high level of discriminant validity for BBS. Conclusion：The BBS has been shown good construct validity in patients with stroke.
