Many of the additional research studies you will be invited to take part in will be looking at depression and/or anxiety with the goal of better understanding these disorders; however, you may also be contacted to take part in other types of research studies. These could be related to other mental or physical health studies indicated from either your questionnaire responses, physical characteristics, or genetic make-up. These studies may be advertised on the website here, or you may be contacted directly to ask whether you might be interested in participating. You are under no obligation to take part in additional studies. You may be invited to take part in up to four additional studies per year.
