To develop a brief, self-administered questionnaire that accurately measures functional capacity and assesses aspects of quality of life, 50 subjects undergoing exercise testing with measurement of peak oxygen uptake were studied. All subjects were questioned about their ability to perform a variety of common activities by an interviewer blinded to exercise test findings. A 12-item scale (the Duke Activity Status Index) was then developed that correlated well with peak oxygen uptake (Spearman correlation coefficient 0.80). To test this new index, an independent group of 50 subjects completed a self-administered questionnaire to determine functional capacity and underwent exercise testing with measurement of peak oxygen uptake. The Duke Activity Status Index correlated significantly (p less than 0.0001) with peak oxygen uptake (Spearman correlation coefficient 0.58) in this independent sample. The Duke Activity Status Index is a valid measure of functional capacity that can be obtained by self-administered questionnaire.
为了开发一种简短的、可自行填写的问卷，以准确测量功能能力并评估生活质量的各个方面，我们对50名接受运动测试并测量峰值摄氧量的受试者进行了研究。所有受试者均由对运动测试结果不知情的访谈者询问其进行各种常见活动的能力。然后制定了一个包含12个条目的量表（杜克活动状态指数），该量表与峰值摄氧量具有良好的相关性（斯皮尔曼相关系数为0.80）。为了测试这个新指数，另一组独立的50名受试者完成了一份自行填写的问卷以确定功能能力，并接受了运动测试及峰值摄氧量测量。在这个独立样本中，杜克活动状态指数与峰值摄氧量显著相关（p小于0.0001）（斯皮尔曼相关系数为0.58）。杜克活动状态指数是一种可通过自行填写问卷获得的有效功能能力测量方法。
