We have recently sent invitation letters to 3G participants who completed our first questionnaire in 2017.
If you have received our invitation to take part in our Hertfordshire 3G Follow-up and are willing to participate, please complete the online form below providing your email address. We will then send an email with a link and instructions on how to complete the online consent form and questionnaire.
If, for any reason, you wish to receive a paper copy, you can let us know here by ticking the box at the end of this form.
By completing this form, you are not committed or obliged to take part in any future research. All our studies are entirely voluntary and you are free to remove yourself from the study at any point.
