1984年3月至10月，在297名55-69岁的芬兰男性中测试了食物频率问卷的生产率和有效性，该问卷旨在测量总脂肪、饱和脂肪和多不饱和脂肪、维生素A、C和E、硒和膳食纤维的摄入量。调查问卷询问了44种食物的消费情况。在再现性研究中，107名受试者以三个月的间隔填写了三次问卷。组内相关性从维生素A的0.52到多不饱和脂肪的0.85不等。在有效性研究中，190名受试者保存了12天的食物消耗记录，平均分布在六个月的时间内，并在此期间之前和之后填写了调查问卷。食物记录中的营养素摄入值与食物频率问卷中的营养素摄入值之间的相关性从硒的0.33到多不饱和脂肪的0.68不等。平均而言，根据食物记录，40-45%的最低和最高五分位数的受试者在通过食物频率问卷评估时处于相同的相应五分位数，70-75%的受试者分别处于两个最低和两个最高问卷五分位数。食物频率问卷和定量食物使用问卷在同一研究中进行了比较。使用这两种仪器在大规模的流行病学研究进行了讨论。
The producibility and validity of a food frequency questionnaire designed to measure intakes of total fat, saturated and polyunsaturated fats, vitamins A, C, and E, selenium, and dietary fiber were tested from March to October 1984 among 297 Finnish men aged 55-69 years. The questionnaire asked about consumption of 44 food items. In the reproducibility study, 107 subjects filled in the questionnaire three times, at three-month intervals. Intraclass correlations varied from 0.52 for vitamin A to 0.85 for polyunsaturated fat. In the validity study, 190 subjects kept food consumption records for 12-two-day periods distributed evenly over a period of six months and filled in the questionnaire both before and after this period. Correlations between the nutrient intake values from the food records and those from the food frequency questionnaires ranged from 0.33 for selenium to 0.68 for polyunsaturated fat. On the average, 40-45% of the subjects in the lowest and highest quintiles based on food records were in the same respective quintiles when assessed by the food frequency questionnaire, and 70-75% were in the two lowest and two highest questionnaire quintiles, respectively. The food frequency questionnaire and a quantitative food use questionnaire tested in the same study were compared. Use of these two instruments in large-scale epidemiologic studies is discussed.
