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.
