This follow-up questionnaire is for completion by our study participants. The questionnaire has been designed to collect up-to-date information about you and your life. The questionnaire is split into several modules and will take about 45-50 minutes to complete.
The questionnaire can be completed in multiple visits. You can save what you’ve done, log out and return to it later by clicking the ‘Save and Exit’ button. Once you click on the ‘Save and Continue’ button, you will not be able to return to that section or edit your answers. Please answer all items as accurately as possible. If you do not recall, please give your best estimate.
For ease of use, we recommend that you complete the questionnaire using a desktop computer, laptop or tablet device.
If you own an Android phone, please consider installing our phone usage app.
