Paper-based DHQ II Forms
Alternate Version AvailableYou are viewing the Web site for the DHQ II, which is the latest version of the DHQ. You may want to see the original version of this information.
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.
- DietCalc QDD file
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.
