Can I use my smartphone or tablet to complete the questionnaire?

Yes, most questionnaires are compatible with a wide range of smartphones, tablets, laptops, and desktop computers. However, some questions may be easier to answer on a larger screen.

I got interrupted or could not finish the questionnaire. Can I log in again to finish it?

Yes, you will be able to log in to the questionnaire as many times as needed. After you log back in at nhs3login.org you will pick up from where you left off; you will not need to start over from the beginning.

How will you use my data?

Questionnaire responses will remain strictly confidential and will only be used for research purposes. For further information on confidentiality and privacy, please click here.
