Dietary Assessment Calibration/Validation Register

Dietary Assessment Calibration/Validation Register


Sharing information in a timely manner can promote more effective research and application. With this goal in mind, the organizers of the First and Second International Conferences on Dietary Assessment supported an effort to establish a register of dietary assessment calibration and validation studies.

Originally, the idea of creating such a register was suggested at the First International Conference on Dietary Assessment in Minneapolis, Minnesota. During 1993, the organizer of the Second International Conference on Dietary Assessment, Walter Willett, M.D., Dr. P.H. (Harvard School of Public Health), in collaboration with Carolyn Clifford, Ph.D. (Sheba Medical Center); Laurence Freedman, Ph.D., Gloria Stables, Ph.D., M.S., R.D. (both formerly of NCI); and NCI's Frances Thompson, Ph.D., circulated a letter and study questionnaires to a wide range of investigators in the field, soliciting information about particular calibration/validation studies. During 1993-1994, study questionnaires were received for 85 calibration/validation studies. Data from these questionnaires were entered into a database and analyzed. Information from the questionnaires was published in the following report and distributed at the Second International Conference on Dietary Assessment Methods in Boston, MA in January 1995.

Following favorable response to the register, the collaborators concluded that the international nutrition and health community could benefit from accessing this information electronically. Additionally, an effort was made to identify published papers about calibration/validation studies and to make the publication abstracts electronically accessible.

As new studies and publications are added to this database, this site will offer a current, reliable source of worldwide activity in the area of dietary assessment calibration/validation studies.
