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.)

Before studies and publications are added to the database, each one is reviewed. The following is a list of studies that are not included in the register:

• Food composition studies
• Studies which assess only household and not individual food consumption
• Reliability studies (studies which administer the same method at multiple times)

The following is a list of publications that are not included in the register:

• Abstracts submitted to conferences
• Publications that only review or comment on other work

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, MN.

If you would like to view the details of one or more studies in the register, then do a study search.

If you would like to view the abstracts of one or more publications in the register, then do a publication search. If you have a study or publication which you think should be included in the register, then add it to the database.

Development and maintenance of this site is a collaborative effort between the Division of Cancer Prevention and the Division of Cancer Control and Population Sciences of the National Cancer Institute. 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.
