对50例关节炎患者在全关节置换术前后进行五项健康状况调查。评估了疼痛、移动性和身体功能、社会角色和社会活动以及全球健康变化测量的相对效率和灵敏度。这些工具具有高度相关的分数，但在某些维度上存在差异。社会和全球结果的工具间差异大于疼痛或流动性。没有一种仪器的性能始终优于其他仪器。描述了一种用于确定相对效率的方法。
Five health status instruments were administered in random order to 50 arthritis patients before and after total joint arthroplasty. Relative efficiency and sensitivity in measurement of change in pain, mobility and physical function, social role and social activity, and global health were assessed. The instruments had highly correlated scores, but had differences in certain dimensions. Inter-instrument differentials were larger for social and global outcomes than for pain or mobility. NO single instrument consistently outperformed the others. A method for determining relative efficiency is described.
