TEDS Studies

TEDS-21

Welcome!

This study involves a series of questionnaires about your twins. It has been designed mainly for desktop and laptop computers, not mobile devices. If you use a phone or tablet and experience any technical problems, please try using a desktop/laptop instead if possible.

The study typically takes around 15 minutes to complete. You can complete it in multiple sessions (e.g., log out or close your browser, then log in again later) if you need to. However, if you participate using this web version, your responses are only saved at specific points, so if you do need to stop, it would be best to do so only at one of the designated 'break points' - it will say on screen where they are. This way, you won't lose any progress when you log back in to continue.

Please answer all questions as best you can even if you are unsure or if the question seems repetitive. We understand that your thoughts and feelings are private. Please be assured that all responses will remain confidential, and will only be read by the researcher. All responses will be kept in accordance with the Data Protection Act 1998. Thank you for taking part in this study. Your contribution is very important to us. If you have any questions or concerns, please contact us by phone on (0800) 317029, or by email at teds-project@kcl.ac.uk.
