Am I eligible to participate?

You may be eligible to participate if you have received a study voucher either in hard copy or electronically from someone you know.

Momentum recruits participants based on a social network model. New partici­pants are always the friends and acqu­aintances of former participants. (See diagram)

Our sampling strategy gives us statist­ically significant data which is invaluable for sexual health research.

Study Overview (10 mins)
Our trained study staff will review the main procedures of the study with you. Participation in this study is entirely voluntary and all information will be kept completely secure and confidential at all times.
Questionnaire (90 mins)
Our questionnaire, which is computer-​based and self-administered, will take approximately 1.5 – 2 hours to complete. You’ll be asked to recall your behaviour in the past six months on topics such as mental health, sexual behaviour, and substance use. The questionnaire will also ask you about your attitudes and beliefs regarding HIV risk, and knowledge of HIV and treat­ment as prevention.
Clinical Component (30 mins)
A registered nurse from VCH will conduct the clinical component of our study. The nurse will collect some brief information about your health, administer a point-of-care rapid HIV test, and collect two small blood samples for syphilis, hepatitis B and C testing. We also offer, at your request, other clinically relevant sexual health services, such as chlamydia and gonorrhea testing and treatment and healthcare referrals.
