Abstract 029: The Automated Self-Administered 24-Hour Dietary Recall (ASA24): A Research Resource from the National Cancer Institute (NCI)

Introduction: Extensive evidence has demonstrated that 24-hour dietary recalls (24HRs) provide high-quality dietary intake data with minimal bias, making them the preferred tool for nutrition monitoring and, potentially, for studying diet and disease associations. Traditional 24HRs, however, are expensive and impractical for large-scale research because they rely on trained interviewers, and require multiple administrations to estimate usual intakes. To address these challenges, NCI developed ASA24. System: The ASA24 system is a publicly available web-based software tool that enables automated and self-administered 24HRs for epidemiologic, intervention, behavioral, or clinical research. ASA24 consists of a Respondent application used by participants to enter recall data and a Researcher application used by researchers to manage study logistics and obtain nutrient and food level data. The format and design of the Respondent application are modeled on USDA’s interviewer-administered Automated Multiple Pass ...
