“…Pearson correlation coefficients observed in this study also compared favorably with those reported in most European studies (17, 30–32), with the exception of two questionnaires recently validated in Italy (19) and Spain (20), showing median correlation coefficients of 0.78 and 0.82, respectively. The higher correlation coefficients could theoretically be explained by the higher number (189 and 113 items, respectively) and the choice of food items, which could better represent dietary intake.…”

“…For the correlation coefficient, when 14 days of dietary information are obtained, no more than 100 should be sufficient (16). Taken together, these recommendations indicate that our study was moderately powered, as is often the case (19, 20, 23), although a number of recent studies have been less powered (18, 28, 29). …”

“…In their review, Cade et al (16) found that the number of items in FFQs published from 1980 and 1999 ranged from 5 to 350 items, with a median of 79 items. Several recent European FFQs contain more than 100 items (10, 13, 17–20). However, according to Willett (9), there is a rapidly decreasing marginal gain in information obtained with increasingly detailed questionnaires.…”

“…The higher correlation coefficients could theoretically be explained by the higher number (189 and 113 items, respectively) and the choice of food items, which could better represent dietary intake. The authors of these studies reported biases in their studies, that is, the use of the same serving size tool in both methods of diet estimation and a quick list used for the 24-HR recall generated from the food items reported in the FFQ (19) or subjects who have been aware of their dietary pattern due to health-related dietary recommendation (20). …”

BackgroundA 50-item self-administered food frequency questionnaire (FFQ) was developed for French adults, to assess the intake of energy, 10 macronutrients, 11 vitamins, and 11 minerals, and to be used in the context of a medical consultation.ObjectiveTo assess the repeatability and relative validity of this FFQ compared to a 7-day diet record (7-DR).DesignA total of 54 and 100 French adults were included in the repeatability and validation studies, respectively. Repeatability was assessed using two FFQs, the second carried out 3 weeks after the first. In the validation study, subjects first completed the FFQ, then the 7-DR the following week. Energy and nutrient intakes were compared using Pearson correlation. The degree of misclassification by the FFQ, compared to the 7-DR, was calculated by a contingency table of quintiles. Bland–Altman plots assessed the correlation between FFQ and 7-DR across the intake range.ResultsRepeatability for intake, explored by Pearson correlation, was 0.62–0.90 (median: 0.81). Relative validity, as determined by Pearson correlation for the nutrient intake derived from the FFQ and 7-DR, was 0.36–0.80 (0.64). The FFQ tended to report higher fiber and micronutrient intake than 7-DR. Misclassification into opposite quintiles ranged 0–6% (1%), whereas classification into same or adjacent quintiles ranged 59–83% (74%). Bland–Altman plots showed good agreement for most nutrients across the range of intake.ConclusionThis new FFQ showed a high repeatability and good relative validity, and thanks to its short length, should be a useful tool for rapidly evaluating the nutrient intake of French adults.
