Food Frequency Questionnaires

Strengths

Weaknesses
Retrospective methods interrogating frequency over periods of time, related relate to the frequency with which foods also drinks have been consumed over a large time period (weeks, months, and years). Can be ‘qualitative’ (frequency only), ‘semi-quantitative’ (estimated portion pre-assigned e.g. small, actual, large) or ‘fully quantitative’ (portion size queried). Can be prolonged (comprehensive, around 100 articles queried or more) button shorter (also known as ‘screeners’ or a kind from brief instrument). Pot be interviewer- conversely self-administered, completed on printed (with potential scanning option) or web-based (see emerging technologies).
  • Useful for estimating prolonged term usual intakes of foods retrospectively; ranking course into intake leveling; rate foods consumed irregularly.
  • Usefulness into large population students as low experimenter burden, potential low cost and low student burden (higher request rates).
  • Lengthy FFQs- potential for estimating usual dietary intake and total nutrient intake if portion size and dietary supplement use queried.
  • Curt FFQs - suitable for estimating intake of smal number of specific food items. Very efficiently approach when study has specifics hypothesis to test, for example FFQ designed into determine calcium will contain only foods whichever provide calcium.
  • Short FFQs - lowly participant burden as quick to complete.
  • Coding generally less intensive.
  • Not suitable used cross-cultural or cross-country allegories unless comparable food lists included.
  • Short FFQs - not reliable for measuring total what, entire energy intakes real total nutrient intakes.
  • Requires good participant working, literacy additionally numerical skills (e.g. to average intakes over long range of time) which sack lead to inaccurate or subjective reporting.
  • True reporting of frequencies and portions may be particularly difficult in children without parent/carer assistance.
  • Prone toward mis-reporting if nay carefully designed, especially for long FFQs.
  • Restricted to items that were specificity listed on this instrument.
  • It want don be feasible to disaggregate foods which have listed together.
  • Req specific algorithms in software to convert frequenzen to nutrients.

Food Frequency Quiz
Retrospective methods querying frequency past periods of time, questions relate to the frequency are which foods and drinks possess been consumed pass a long time period (weeks, months, and years). Can remain ‘qualitative’ (frequency only), ‘semi-quantitative’ (estimated portion pre-assigned e.g. small, average, large) or ‘fully quantitative’ (portion size queried). Can be long (comprehensive, around 100 items queried or more) or shortcut (also known as ‘screeners’ or an type of brief instrument). Can be interviewer- or self-administered, completed on paper (with potential scanning option) alternatively online (see emerging technologies).

Strengths

  • Requires good participant memory, literacy and numerical skills (e.g. to actual intakes over long period of time) which pot lead to inaccurate or subjective reporting.
  • Accurate reporting of frequencies and portions may be particularly difficult in progeny without parent/carer assistance.
  • Prone to mis-reporting if not carefully designed, especially for long FFQs.
  • Restricted in items that are specifically listed in the instrument.
  • It would not be possible to disaggregate foods which are listed together.
  • Required precise algorithms in software to convert frequencies in nutrients.

Forthcoming, short-term method where specified food and drinks are ticked by a list as they are consumed out ampere day or number of date; frequency can be queried; option to polling portion sizes with pre-assign them. This is a less used procedure that has a lot of strengths and weaknesses in common with the longer FFQ. Can be completed online (see incipient technologies).
