What is a short food frequency questionnaire?
This tool is an non-quantitative, paper based, short food frequency questionnaire, which includes 25 food items and focuses on fruit, vegetables, fibre-rich foods, high fat and high-sugar foods, meat, meat products and fish. The aim of the tool was to measure diet quality for population surveys.
Are FFQs reliable?
Cronbach’s alpha values (0.708 to 0.824) and intraclass correlation coefficients (0.710 to 0.826) showed good agreement between repeated FFQs. The results suggest that the FFQ has acceptable validity and good reliability. Hence, the FFQ can be used to assess preschool children’s food intake.
How reliable are food frequency questionnaires?
The findings from this study suggest that the FFQ has good reliability and acceptable validity when compared to a 3-day dietary record.

Which is easier, a 24 hour food recall or a FFQ?
FFQs can be easier and less time-consuming to implement than a 24-hour Dietary Recall, if the food list is relatively short (e.g. <100 items) FFQs require substantial up-front investment to develop and validate the instrument (food list and quantities) for a given context or country.
