很少有食物频率调查表被评估其评估可能与疾病相关的独立于其营养成分的个别食物的摄入量的能力。通过131项半定量食物频率问卷对来自卫生专业人员随访研究（一项关于饮食和疾病的大型纵向研究）的127名男性样本进行了食物摄入量测量的重现性和有效性评估。每个受试者完成两份问卷，间隔1年，两个1周的饮食记录，间隔6个月，在干预年。皮尔森相关性评估两份问卷中食物摄入量之间的可重复性，范围从馅饼的0.31到咖啡的0.92（平均值= 0.59）。通过比较第二份问卷的食物摄入量与饮食记录的食物摄入量来衡量有效性。皮尔森相关性校正了饮食记录数据中的人内每周变化，范围从其他坚果的0.17到香蕉的0.95（平均值= 0.63）。大的人内变异排除了29种食物的准确有效性相关性的计算。正如我们之前在女性中观察到的那样，最常被高估的食物是水果和蔬菜，而肉类和乳制品最常被低估。除了少数例外，在这个广泛的食物频率问卷中，观察到个体食物摄入的合理水平的再现性和有效性。
Few food frequency questionnaires have been evaluated for their ability to assess intakes of individual foods that may be related to disease independently of their nutrient content. The reproducibility and validity of food intake measurements by a 131-item semiquantitative food frequency questionnaire were evaluated in a sample of 127 men from the Health Professionals Follow-up Study, a large longitudinal study of diet and disease. Each subject completed two questionnaires 1 year apart and two 1-week diet records 6 months apart during the intervening year. Pearson correlations assessing reproducibility between food intakes from the two questionnaires ranged from .31 for pie to .92 for coffee (mean =.59). Validity was measured by comparing food intakes from the second questionnaire with those from the diet records. Pearson correlations corrected for within-person weekly variation in diet record data ranged from .17 for other nuts to .95 for bananas (mean =.63). Large within-person variation precluded the calculation of accurate validity correlations for 29 foods. As we previously observed in women, the foods most often overreported were fruits and vegetables, and meats and dairy products were most often underreported. With few exceptions, reasonable levels of reproducibility and validity were observed for intake of individual foods in this extensive food frequency questionnaire.
