Evaluation of the clinimetric properties of the Barthel Index.
To measure disabilities in activities of daily living (ADL) and mobility by independent observers.
Clinical and outpatient departments of Neurology of the University Medical Centre, Amsterdam.
In 35 patients of the clinical and 25 patients of the outpatient department the stroke disabilities were assessed independently by three observers. The Barthel Index was evaluated in terms of score agreements, homogeneity, and construct validity.
There was an excellent concordance of total scores (mean kappa = 0.88; range 0.85-0.90) and single item scores (range mean values of kappa = 0.82-1.00). Repeated analyses, after exclusion of patients with maximum total scores, did not result in a significant reduction of these kappa values. The Barthel Index was a highly homogeneous scale (Cronbach's alpha = 0.96). All items contributed to this reliability in a balanced way. Factor analysis showed that the items on the scale described one common underlying trait. This factor explained 81% of the score variance.
The Barthel Index is a sound instrument to measure disabilities in ADL and mobility. The scale is suitable for use in both patient care and research.
评估巴氏指数的临床测量特性。
由独立观察者测量日常生活活动(ADL)和移动能力方面的残疾情况。
阿姆斯特丹大学医学中心神经内科的临床科室和门诊科室。
临床科室的35名患者和门诊科室的25名患者由三名观察者独立评估中风残疾情况。从得分一致性、同质性和结构效度方面评估巴氏指数。
总分(平均kappa值 = 0.88;范围0.85 - 0.90)和单项得分(kappa值范围平均值 = 0.82 - 1.00)具有极佳的一致性。排除总分最高的患者后进行重复分析,这些kappa值并未显著降低。巴氏指数是一个高度同质的量表(克朗巴哈系数α = 0.96)。所有项目以平衡的方式对这种可靠性有贡献。因子分析表明量表上的项目描述了一个共同的潜在特征。该因子解释了得分方差的81%。
巴氏指数是测量ADL和移动能力方面残疾情况的可靠工具。该量表适用于患者护理和研究。
