Oxford WebQ Questionnaire

We developed an online dietary questionnaire, the Oxford WebQ, to ask participants about what they had to eat and drink the previous day. This has been used in the UK Biobank, the Million Women Study, and other prospective studies. 

The Oxford WebQ is a validated web-based 24 hour dietary assessment tool developed for repeated administration in large prospective studies. It is a self-administered low-cost method for measuring dietary intake, and in our evaluation it took a median of 12·5 minutes to complete. Nutrients are estimated automatically. 

If you want to use the Oxford WebQ in your study please email oqs.admin@ndph.ox.ac.uk. 

If you are already using the Oxford WebQ and have a general inquiry please email dietweb@ceu.ox.ac.uk.
