No. Once you have registered your interest, the website will check if your details match to any of the current studies, and then continue to check automatically every time new studies are added. It may take some time to match to a study, as explained in “Will I match to a study?” When a match is found, you will be contacted through your preferred manner (by phone, email or letter). Detailed information will then be provided about the study, both through the website and by the researcher, and you will have the opportunity, only if you wish to do so, to answer any further screening questions. You may ask as many questions as you like. You can then decide if you want to take part, and can stop taking part at any time.
