Abstract: The validity of results from studies assessing the impact of nutritional factors on health depends directly on the quality of dietary assessment tools. All dietary assessment methods have strengths and weaknesses and are subject to bias. The 24-hour dietary recall (24HDR), where an interviewer asks the participant to report all foods and beverages consumed during the last 24 hours, is increasingly used in epidemiology due to validation studies using biomarkers that have demonstrated that repeated 24HDR could provide high quality dietary intake data with minimal bias. However, this tool is considered expensive since it depends on trained professionals for both its administration and the coding of responses in nutritional databases. The development of web-based assessment tools appears as an economical solution in a context where it is increasingly easy to reach Canadians through a web application. It is in this context that an automated, self-administered web-based 24-hour recall, the R24W, was developed at INAF, Laval University. The objective of this study is to describe the development of this new dietary assessment tool and to discuss the impact of its use in nutrition research.
