The reproducibility and validity of self-administered questionnaires on physical activity and inactivity were examined in a random (representative) sample of the Nurses' Health Study II cohort and a random sample of African-American women in that cohort.
Repeat questionnaires were administered 2 years apart. Past-week activity recalls and 7-day activity diaries were the referent methods; these instruments were sent to participants four times over a 1-year period.
The 2-year test-retest correlation for activity was 0.59 for the representative sample (n = 147) and 0.39 for the African-American sample (n = 84). Correlations between activity reported on recalls and that reported on questionnaire were 0.79 and 0.83 for the representative and African-American samples, respectively. Correlations between activity reported in diaries and that reported on questionnaire were 0.62 and 0.59, respectively. Test-retest coefficients for inactivity were 0.52 and 0.55, respectively. Correlations between inactivity reported in diaries and that reported on questionnaire were 0.41 and 0.44, respectively.
The simple, short questionnaires on activity and inactivity used in the Nurses' Health Study II are reasonably valid measures for epidemiological research.
在护士健康研究II队列的随机（代表性）样本以及该队列中的非裔美国女性随机样本中，对关于身体活动和不活动的自我管理问卷的可重复性和有效性进行了检验。
每隔2年发放重复问卷。过去一周的活动回忆和7天活动日记作为参照方法；这些工具在1年时间内分4次发送给参与者。
代表性样本（n = 147）的活动2年重测相关性为0.59，非裔美国样本（n = 84）为0.39。回忆报告的活动与问卷报告的活动之间的相关性，代表性样本和非裔美国样本分别为0.79和0.83。日记报告的活动与问卷报告的活动之间的相关性分别为0.62和0.59。不活动的重测系数分别为0.52和0.55。日记报告的不活动与问卷报告的不活动之间的相关性分别为0.41和0.44。
护士健康研究II中使用的关于活动和不活动的简单、简短问卷是流行病学研究中合理有效的测量方法。
