广泛使用的健康习惯和历史问卷（HHHQ）估计“通常过去一年”的营养素摄入量的再现性进行了检查。在三个不同季节的三个场合中，68名女性（平均年龄43岁）在适当的季节提供了所有三个问卷的可用数据。组内相关性（ICC）在三个管理范围从0.56（胡萝卜素）到0.82（脂肪作为能量的百分比），中位数为0.72。因此，可靠性是中度至良好，和季节的管理/ordinality一般对个人的排名影响不大。第一次给药（冬季）时，能量和一些营养素摄入量的点估计值较高。除了膳食纤维和可能的胡萝卜素，大多数差异消失时，调整能量使用营养密度的方法，以及使用重复测量回归模型。第一次给药时的较高摄入量可能更多地是由于学习或疲劳效应，而不是季节性食物供应对“通常"摄入量的影响。这些数据应在未来与有效性数据结合使用，以帮助评估组平均值（以及这些平均值的变化）的精确度的增益，并改善营养素和血清值等因素之间的比值比和相关性的估计，如果问卷调查进行了多次管理。
The reproducibility of the widely, used Health Habits and History Questionnaire (HHHQ) for estimating ''usual past-year'' nutrient intake was examined. The HHHQ was self-administered on three occasions during three different seasons, 68 women (avg age 43 yrs) provided usable data for all three questionnaires in the appropriate seasons. Intraclass correlations (ICC) among the three administrations ranged from 0.56 (carotene) to 0.82 (fat as percentage of energy), with a median of 0.72. Thus, reliability was moderate to good, and season of administration/ordinality generally had little impact on ranking of individuals. The point estimates of intake of energy and a number of nutrients were higher in the first administration (winter). Except for dietary fiber and possibly carotene, most differences disappeared when adjusted for energy using a nutrient density approach, as well as using repeated-measures regression models. The higher intake in the first administration may be due more to either learning or fatigue effects rather than an effect of seasonal food availability on perceptions of ''usual'' intake. These data should be used in conjunction with validity data in the future to help evaluate the gain in precision of group means (and changes in these means) and improved estimates of odds ratios and correlations between nutrients and factors such as serum values, if a questionnaire is administered more than once.
