Dietary Assessment Calibration/Validation Register

Dietary Assessment Calibration/Validation Register

Welcome to the Dietary Assessment Calibration/Validation (DACV) Register, a register of calibration/validation studies and publications. The register contains studies and publications which compare dietary intake estimates from two or more dietary assessment methods. Dietary assessment methods include:

  • Food records or diaries (including weighed intakes)
  • Dietary recalls
  • Food frequency questionnaires (FFQ's)
  • Dietary histories
  • Observed intakes
  • Chemical analyses of duplicate collections of foods consumed
  • Biological assessments (e.g. doubly-labelled water, plasma carotene, etc.)

Excluded from the register are studies related to food composition, studies which assess only household (not individual) consumption, and reliability studies (studies which administer the same method multiple times). Additionally, abstracts or publications that only review or comment on other work are excluded from the register.

Note: inclusion of a study in the Diet Assessment Calibration/Validation Register does not imply NCI approval or review of the study protocol or its results.

The history of this effort dates back to 1993 when the idea for creating such a register was suggested at the First International Conference on Dietary Assessment in Minneapolis, Minnesota.

Development and maintenance of this site is a collaborative effort between the National Cancer Institute's (NCI) Division of Cancer Prevention and the Division of Cancer Control and Population Sciences. It has been developed as a means of keeping the international nutrition and health community aware of calibration/validation studies on dietary assessment methods being conducted worldwide.
