Paper-based DHQ II Forms
The DHQ II that queries intake for the past year and includes portion size is
the standard version of the NCI's Diet History Questionnaire for which there are
related validation data. There, are, however, four different versions available
for use, described below. Please note that the example forms provided SHOULD
NOT be copied and completed by research subjects unless you intend to input the
data by hand. The questionnaires for analysis are best administered on printed, scannable forms that you can order and have
scanned at your own expense.
- Past year, with portion size (our standard FFQ format): asks about intake in the past year and includes questions about portion size.

The DHQ is available in a variety of file formats, each designed for a
specific method of capturing the data from paper-based forms. Review the options
below and determine the method that you will use to capture the data before
downloading and printing copies for distribution. The DHQ and other required
files are available on each method's page. A Web-based
version of the DHQ II is also available as an option for capturing data.
DHQ data from paper-based forms are stored in an ASCII text file that can be
analyzed using the Diet*Calc software. Please be
aware that although Diet*Calc is available at no cost, there are costs
associated with printing the forms and with scanning or entering the data. There
are two methods for capturing survey data from paper forms: optical scanning and data entry.
To date, scanning has proven to be the most
effective data collection method for the paper-based DHQ. Information regarding all
methods is posted below. When
possible, we have included information regarding the costs involved.
Users may be able to reduce costs by sharing information and resources with
other users. Any new information we know of regarding economical printing,
scanning, or data entry methods will be posted here as it becomes available. If
you would like to submit information regarding your experience with the DHQ,
please contact
the technical support
staff. If you would like to share information with other researchers, please
