The Barthel Index is a valid measure of disability. In this study we investigated the reliability of four different methods of obtaining the score in 25 patients: self-report, asking a trained nurse who had worked with the patient for at least one shift, and separate testing by two skilled observers within 72 hours of admission. Analysis of total (summed) scores revealed a close correlation between all four methods: a difference of 4/20 points was likely to reflect a genuine difference. In individual items, most disagreement was minor and involved the definition of middle grades. Asking an informed nurse or relative was as reliable as testing, and is quicker.
巴氏指数是一种有效的残疾测量方法。在本研究中，我们调查了25名患者中获取该评分的四种不同方法的可靠性：自我报告、询问与患者共事至少一个班次的训练有素的护士，以及在入院72小时内由两名熟练的观察者分别进行测试。总分（累加得分）分析显示，所有四种方法之间存在密切相关性：4/20分的差异很可能反映了真实差异。在各个项目中，大多数分歧较小，涉及中等等级的定义。询问有见识的护士或亲属与测试一样可靠，而且更快。
