Abstract

The aim of the present study was to assess reproducibility and relative validity of a self-administered FFQ used in the PREDIMED Study, a clinical trial for primary prevention of CVD by Mediterranean diet in a population at high cardiovascular risk. The FFQ was administered twice (FFQ1 and FFQ2) to explore reproducibility at 1 year. Four 3 d dietary records (DR) were used as reference to explore validity; participants therefore recorded their food intake over 12 d in the course of 1 year. The degree of misclassification in the FFQ was also evaluated by a contingency table of quintiles comparing the information from the FFQ2 and the DR. A total of 158 men and women (aged 55–80 years) were asked not to modify their dietary habits during the study period. Reproducibility for food groups, energy and nutrient intake, explored by the Pearson correlation coefficient ( r ) ranged 0·50–0·82, and the intraclass correlation coefficient (ICC) ranged from 0·63 to 0·90. The FFQ2 tended to report higher energy and nutrient intake than the DR. The validity indices of the FFQ in relation to the DR for food groups and energy and nutrient intake ranged ( r ) from 0·24 to 0·72, while the range of the ICC was between 0·40 and 0·84. With regard to food groups, 68–83 % of individuals were in the same or adjacent quintile in both methods, a figure which decreased to 55–75 % for energy and nutrient intake. We concluded that FFQ measurements had good reproducibility and a relative validity similar to those of FFQ used in other prospective studies.

  • The FFQ used for nutritional assessment was a validated 143-item food frequency questionnaire from the PREDIMED study, adapted for the Spanish population.

    “A validated 143-item food frequency questionnaire (FFQ) from the PREDIMED study, adapted for the Spanish population [22], was used to collect data on the participants’ habitual dietary patterns over the previous year.”

    From Efficacy of Power Training on Sarcopenic Obesity in Community-Dwelling Older Women: A 32-Week Randomized Clinical Trial (2025) · cites this paper as [22]

    The Materials and methods section says the PREDIMED FFQ was adapted from a previously validated Spanish questionnaire, and the Discussion reports acceptable validity. But both sections identify it as a 137-item FFQ, not a 143-item one. The Results section confirms that the FFQ assessed intake over the previous year; page numbers are unavailable in our copy.

  • At baseline and each annual visit, a 14-item MedDiet adherence questionnaire, a 137-item validated food frequency questionnaire, and the validated Spanish version of the Minnesota Leisure-Time Physical Activity questionnaire were administered.

    “At baseline and at each annual visit we administered 1 ) a short-questionnaire about lifestyle variables, medical conditions, and medication use, 2 ) a 14-item questionnaire of adherence to the MedDiet ( 12 ), 3 ) a 137-item validated food frequency questionnaire ( 13 ), and 4 ) the validated Spanish version of the Minnesota Leisure-Time Physical Activity questionnaire ( 14 ).”
  • A previously modified, adapted and validated food frequency questionnaire with portion sizes and food groups usually consumed by the Spanish child population was used.

    “A previously modified, adapted and validated food frequency questionnaire (FFQ) with the portion sizes and food groups usually consumed by the Spanish child population was used [30].”
  • Fiber intake was calculated using the Spanish food composition tables and through a validated food frequency questionnaire.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
