In recent years it has become increasingly apparent that the validity of the food frequency questionnaire (FFQ) approach to assessing dietary intake is inadequate. Although there are other dietary assessment methodologies with superior validity (24‐hour dietary recalls and food records) they are not feasible for use in large epidemiologic studies where participant burden and measurement costs are key considerations. To address the need for a valid and feasible approach to assessing diet in large studies we developed a 24‐hour dietary recall questionnaire (DRQ) that may be self‐administered and optically scanned or key entered. A preliminary evaluation of this questionnaire was conducted in a sample of adults (n=57) who were asked to complete the DRQ and a telephone 24‐hour dietary recall (reference measure) for concurrent days. Mean intake estimates from the recalls and the DRQs were similar for most (18 of 20) nutrients examined. For example, average energy intake estimates from the recalls and DRQs were 2176 kcals and 2297 kcals, respectively (p=0.25). Correlations between nutrient intakes estimates from the recalls and DRQs ranged from 0.31 for trans fat (p
