A validated physical activity questionnaire for young adults was adapted and validated for use in free living, apparently healthy people, aged 63-80 yr. Test-retest reliability of the questionnaire on 29 participants was 0.89 as determined by Spearman's correlation coefficient. Further classification by tertiles of activity resulted in 72% of the participants being correctly classified and 0% grossly misclassified on two separate occasions. In a similar group of 31 subjects, classifications based on questionnaire activity scores were compared with classifications obtained by repeated 24-h activity recalls and pedometer measurements, showing Spearman's correlations of 0.78 and 0.73, for both methods, respectively. Seventy-one and 67% of the subjects, respectively, were classified in the same activity tertile for both methods. It is concluded that the questionnaire provides a reliable and valid method for classifying elderly subjects into categories of high, medium, and low physical activity.
一份经过验证的针对年轻人的体力活动问卷，经过改编和验证后，可用于63至80岁自由生活、表面健康的人群。根据斯皮尔曼相关系数确定，29名参与者的问卷重测信度为0.89。按活动三分位数进一步分类后，72%的参与者在两个不同场合被正确分类，0%被严重错误分类。在另一组31名受试者中，将基于问卷活动得分的分类与通过重复24小时活动回忆和计步器测量获得的分类进行比较，两种方法的斯皮尔曼相关系数分别为0.78和0.73。两种方法分别有71%和67%的受试者被归为同一活动三分位数。结论是，该问卷为将老年受试者分为高、中、低体力活动类别提供了一种可靠且有效的方法。
