It was originally printed in 1998, reprinted in 2002 with minor changes to the front page and the development of a Spanish translation, and reprinted again in 2007 with changes to the Today's Date field to include the years 2007-2011.

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. As of August 2005, a Web-based version of the DHQ is also available as an option for capturing data.
DHQ data stored in an ASCII text file can be analyzed using the Diet*Calc software. Please be aware that although Diet*Calc is available at no cost, there may be costs associated with printing the forms and with scanning or entering the data. There are 3 methods for capturing survey data -- scanning, data entry, and computer-assisted interviews. To date, scanning has proven to be the most effective method for DHQ. However, information regarding all methods will be posted in the links below as it becomes available. When possible, we have included information regarding the costs involved.
