The efficacy of all dietary studies, whether aimed at monitoring a population's diet, understanding diet and health relationships, or evaluating the effect of an intervention, depends on appropriate assessment of intakes. Determining the most suitable dietary instrument for a particular study can be a challenge and is dependent upon a number of considerations, including the specific research question, dietary components of interest, study design, and target population. The National Cancer Institute has developed an online resource to provide guidance on the selection of appropriate dietary assessment methodologies for characterizing the intakes of a group or groups and to outline various considerations for the use of each. The Dietary Assessment Primer describes the major types of self‐report instruments; provides guidance on using the instruments alone or in combination to address different research questions; compares key features of each instrument; explains validity, measurement error, and calibration in the context of dietary assessment; provides expanded information about particular key topics; and includes a Glossary of basic terms and an extensive list of References and Resources. The online tool was developed by subject matter experts within NCI, with internal and external review to ensure the content reflects the current state of the science. User‐centered design principles were applied to developing the web‐based interface to ensure optimal usability. The Primer is intended to help researchers collect the highest quality dietary data possible given their study resources and constraints, with the ultimate goal of improving our capacity to monitor diets among populations and understand how diet affects health.
