美国国家癌症研究所的研究人员开发了一种新的基于认知的食物频率问卷（FFQ），饮食历史问卷（DHQ）。美国餐桌上的饮食研究试图验证和比较DHQ与Block和Willett FFQ。1997年，在从全国代表性样本中招募的1 640名男性和女性中，1 301人完成了四次24小时电话召回，每个季节一次。受试者随机接受DHQ和阻滞FFQ或DHQ和Willett FFQ。采用标准测量误差模型，估计的真实性与DHQ、Block FFQ和Willett FFQ之间的能量相关性分别为0.48、0.45和0.18（女性），0.49、0.45和0.21（男性）。对于26种营养素，DHQ与块FFQ的相关性和衰减系数略高，并且在未调整能量的模型中均优于Willett FFQ。能量调整显著增加了Willett FFQ的相关性和衰减系数，并适度增加了DHQ和Block FFQ仪器的相关性和衰减系数。DHQ整体表现最好。这些数据表明，DHQ和Block FFQ在估计绝对摄入量方面比Willett FFQ更好，但在能量调整后，所有三种方法在评估饮食疾病风险方面更具可比性。
Researchers at the National Cancer Institute developed a new cognitively based food frequency questionnaire (FFQ), the Diet History Questionnaire (DHQ). The Eating at America's Table Study sought to validate and compare the DHQ with the Block and Willett FFQs. Of 1,640 men and women recruited to participate from a nationally representative sample in 1997, 1,301 completed four telephone 24-hour recalls, one in each season. Participants were randomized to receive either a DHQ and Block FFQ or a DHQ and Willett FFQ. With a standard measurement error model, correlations for energy between estimated truth and the DHQ, Block FFQ, and Willett FFQ, respectively, were 0.48, 0.45, and 0.18 for women and 0.49, 0.45, and 0.21 for men. For 26 nutrients, correlations and attenuation coefficients were somewhat higher for the DHQ versus the Block FFQ, and both were better than the Willett FFQ in models unadjusted for energy. Energy adjustment increased correlations and attenuation coefficients for the Willett FFQ dramatically and for the DHQ and Block FFQ instruments modestly. The DHQ performed best overall. These data show that the DHQ and the Block FFQ are better at estimating absolute intakes than is the Willett FFQ but that, after energy adjustment, all three are more comparable for purposes of assessing diet-disease risk.
