Evaluation of a web-based, pictorial diet history questionnaire
Open accessAbstract
Objective: To develop and evaluate a pictorial, web-based version of the NCI diet history questionnaire (Web-PDHQ). Design: The Web-PDHQ and paper version of the DHQ (Paper-DHQ) were administered 4 weeks apart with 218 participants randomised to order. Dietary data from the Web-PDHQ and Paper-DHQ were validated using a randomly selected 4 d food record recording period (including a weekend day) and two randomly selected 24 h dietary recalls during the 4 weeks intervening between these two diet history administrations. Setting: Research office in Reston, VA, USA. Participa414ts: Computer-literate men and women recruited through newspaper advertisements. Results: Mean correlation of energy and the twenty-five examined nutrients between the Web-PDHQ and Paper-DHQ was 0·71 and 0·51, unadjusted and energy-adjusted by the residual method, respectively. Moderate mean correlations (unadjusted 0·41 and 0·38; energy-adjusted 0·41 and 0·34) were obtained between both the Web-PDHQ and Paper-DHQ with the 4 d food record on energy and nutrients, but the correlations between the Web-PDHQ and Paper-DHQ with the 24 h recalls were modest (unadjusted 0·31 and 0·29; energy-adjusted 0·37 and 0·26). A subset of participants (n 48) completing the Web-PDHQ at the initial visit performed a retest on the same questionnaire 1 week later to determine repeatability, and the unadjusted mean correlation was 0·82. Conclusions: These data indicate that the Web-PDHQ has comparable repeatability and validity to the Paper-DHQ but did not improve the relationship of the DHQ to other food intake measures (e.g. food records, 24 h recall).

The average unadjusted correlation coefficient of .47 compared favorably with the range reported by similar validation studies comparing FFQ with food records: .34-.46.
“The average unadjusted correlation coefficient of .47 compared favorably with the range reported by similar validation studies comparing FFQ with food records: .34-.46 [31-32,34,41].”

The pattern of higher estimated energy and nutrient intakes on the first administration of the Food4Me FFQ has been observed in numerous other reproducibility studies.
“This pattern has been observed in numerous other reproducibility studies [21,31-32], and is proposed to result from learning effects and questionnaire fatigue [39].”

The mean unadjusted correlation coefficient (r=.75) for energy and nutrient intake compared well with previous studies on both computerized and non-Web-based FFQ.
“The mean unadjusted correlation coefficient (r=.75) for energy and nutrient intake compared well with previous studies on both computerized [21,30-31] and non-Web-based FFQ [23,32-35].”

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.
