Abstract

Objective: To assess the perceived outcomes associated with diet/food intake in the general adult population. Design and subjects: The Food Benefits Assessment (FBA©) questionnaire was developed from subjects’ verbatim transcripts (n 18) and after comprehension tests (n 5). Normal-weight (n 130) and overweight (n 67) subjects then completed the final questionnaire twice, 7 d apart. Psychometric properties were assessed, including construct validity by principal components analysis (PCA), concurrent validity (Spearman coefficient) with the Short Form-36 scale (SF-36), known-group validity by comparing FBA dimension scores according to lifestyle and clinical variables, internal consistency reliability (Cronbach’s α) and test–retest reproducibility in stable subjects over 1 week (intraclass correlation coefficient, ICC). Results: PCA and Multitrait analysis confirmed the final version of the FBA comprising forty-one items split into seven dimensions (vitality; digestive comfort; physical appearance; well-being; snacking; disease prevention; aesthetics). All dimensions displayed good item convergent validity (0·44 to 0·80), good concurrent validity (highest correlation between well-being dimension of FBA and mental health scale of SF-36, r = 0·83) and good known-group validity and reproducibility (ICC ≥ 0·76); internal consistency reliability was good to excellent (Cronbach’s α = 0·79 to 0·91). Conclusion: The FBA is the first valid and reliable questionnaire that allows the assessment of diet effects and impact as perceived by subjects. It is a good candidate in the nutrition field for further use in specific population settings and with a particular food or daily diet. Linguistically validated English (UK and US) and German versions of the questionnaire are available.

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.
