We have designed specialized food frequency questionnaires for various population groups. We offer scannable paper forms. Once forms are completed and sent back to DAC they are quality controlled and a nutrient daily report per subject is sent to you in 2 to 3 weeks.
We have an OpScan 6 Scanner, optical mark reader (OMR) from Pearson Assessments. The scanner has an information dual-side, reflective read head for faster two-sided document scanning, and is set up for automated processing of food frequency questionnaires. Using scannable forms, data are quickly and accurately scanned and then linked to our nutrient database for processing to nutrient information.
Portion Size Tools
We use Nasco food models (http://www.enasco.com/product/WA21359HR) to assist subjects in identifying their food portion sizes. We also use the Food Portion Booklet which is used to assist with telephone interviews.
