Currently, the interviewer-administered 24-hour dietary recall (24HR) is considered the best dietary data collection methodology. It provides the highest quality and least biased food intake data for a single day (past 24 hours). The newly developed web-based Automated Self-Administered 24-hour Recall (ASA24) transforms 24HR methodology into a convenient, self-administered, low-cost method of collecting dietary intake data. Because it is web-based, self-administered, and uses 24HR methodology, the ASA24 makes it feasible to collect multiple days of dietary intake data in large-scale studies. The web-based, automated data collection system also offers the advantage of automated coding of food items and calculation of nutrient intakes. A single day of 24HR data will be collected from a sample of eligible participants either once or twice within a six week period using the ASA24 and the AMPM. Dietary intake from the new ASA24 method will be compared to dietary intake data from the standard AMPM method. The findings from this study will provide information on the feasibility and validity of the ASA24 relative to the standard AMPM methodology. The ASA24 method would offer a low-cost alternative to the AMPM method, and thus could allow a wider use of 24HR methodology within existing resources.

This adjustment is an extension of the previously approved project. The ASA24 Respondent application is currently available as a beta version only. There has been a delay in the completion of a fully functional Version 1 due to a contractual conflict over intellectual property rights with a subcontractor who designed the graphic user interface. A virtual work stoppage occurred for approximately a year as legal and contractual issues were discussed with contracts staff, legal counsel, and contractors. Ultimately, NCI decided to develop a new graphical user interface for the respondent application. This work began in August of 2010 with a new contract in place. Progress has been substantial and continuous. Version 1, which is ultimately the ASA24 tool that will be available to the public in the future, will be free of the bugs in the beta version and will offer improved functionality and features, such as additional optional modules (e.g., supplement intake) and a Spanish language option is expected to be available in the summer of 2011. The burden has decreased slightly since last submission as a result spreading the same number of anticipated participants over a period of 3 years, rather than 2 years, which was the time frame requested in the 2009 submission.
