Food frequency questionnaire (FFQ)

A food frequency questionnaire (FFQ) consists of a finite list of foods and beverages with response categories to indicate usual frequency of consumption over the time period queried [NIH Dietary Assessment Primer (https://dietassessmentprimer.cancer.gov/profiles/)].

code "C94817" (Food Frequency Questionnaire) from code system "FDA RouteOfAdministration"
Diet history

The diet history method is a detailed retrospective dietary assessment which obtains details of individual foods, and comprehensive information about foods eaten less regularly. It is used to describe usual food and / or nutrient intakes over months or a year [DAPA-Toolkit (https://dapa-toolkit.mrc.ac.uk/diet/subjective-methods/diet-history)].

code "C17994" (Dietary History) from code system "FDA RouteOfAdministration"
24-h dietary recall

A 24-hour dietary recall (24HR) is a structured interview intended to capture detailed information about all foods and beverages consumed by the respondent in the past 24 hours, most commonly, from midnight to midnight the previous day [NIH Dietary Assessment Primer (https://dietassessmentprimer.cancer.gov/profiles/)].

code "118" (24-h dietary recall) from code system "NFDI4Health_CS_MDS_Remaining_Concepts"
Food record

A food record (also called a food diary) is a self-reported open-ended account of all foods and beverages consumed by a respondent over one or more days [NIH Dietary Assessment Primer (https://dietassessmentprimer.cancer.gov/profiles/)].

code "120" (Food record) from code system "NFDI4Health_CS_MDS_Remaining_Concepts"
Screener

Screeners, also called short dietary assessment instruments: A short food frequency questionnaire, usually without portion size questions or a behavioral questionnaire that asks about general dietary practices (for example, "Do you generally butter your bread?") [NIH Dietary Assessment Primer (https://dietassessmentprimer.cancer.gov/profiles/)].

DietAssessment.validity
Relationship
Rationale

Indication whether the dietary assessment instrument was validated. Validity refers to whether an instrument accurately measures what it is intended to measure. This is typically assessed by comparison to a gold standard using methods like correlations or Bland-Altman plots. It indicates how suitable the instrument is for its purpose and whether it can be applied to other populations beyond the original study.
