我们评估了一项前瞻性研究中使用的51,529名男性自我管理的体力活动问卷的可重复性和有效性。调查问卷通过邮件管理两次，238名参与者相隔2年。在此期间，参与者完成了过去一周的回忆和一周的活动日记，对应于一年中不同季节的四次。此外，研究参与者的一个子集进行了台阶休息。用于测量再现性的组内相关系数分别为0.39不活动，0.41 nonventricular活动，和0.52剧烈活动。根据日记测量值的变化进行调整后，基于日记和基于日记的活动评分之间的相关性为：不活动为0.41，非剧烈活动为0.28，剧烈活动为0.58。活动分数的分布在问卷和过去一周回忆的平均值之间是相似的，这表明参与者能够将季节性变化纳入问卷的回忆中。剧烈活动与静息脉搏的相关系数为-0.45，而踏步后脉搏率的相关系数为-0.41。这些数据表明，这种体力活动问卷是可重复的，并提供了一个有用的措施，平均每周活动，特别是剧烈活动，超过1年的时间。
We assessed the reproducibility and validity of a self administered physical activity questionnaire used in a prospective study of 51,529 men. The questionnaire was administered by mail twice to 238 participants 2 years apart. During this interval, the participants completed a past week recall and a 1-week activity diary at four times corresponding to different seasons throughout a year. Also, a step rest was taken by a subset of the study participants. The intraclass correlation coefficients used to measure reproducibility were 0.39 for inactivity, 0.41 for nonvigorous activity, and 0.52 for vigorous activity. The correlations between diary-based and questionnaire-based activity scores, adjusted for variation in the diary measurements, were 0.41 for inactivity, 0.28 for nonvigorous activity, and 0.58 for vigorous activity. The distribution of activity scores was similar between the questionnaires and the average of past-week recalls, indicating the participants' ability to incorporate seasonal variation into their recall on a questionnaire. The cor relation between vigorous activity and resting pulse was -0.45, whereas, for the pulse rate after stepping, the correlation was -0.41. These data indicate that this physical activity questionnaire is reproducible and provides a useful measure of average weekly activity, particularly vigorous activity, over a 1-year period.
