*recruitment in progress*

A sequel to the Engage Cohort Study, this multiphase, sequential mixed-methods biopsychosocial study aims to examine factors that influence the mental and sexual health of gay, bisexual, and queer (GBQM) men in Canada. This is a national team project with collaboration from institutions across 4 provinces and recruitment will be conducted in 4 major cities: Toronto, Vancouver, Montreal, and Winnipeg. 

Participants of this study will be invited to come back for 5 study visits. Each visit is made up of 2 components: (1) a comprehensive questionnaire consisting of informational, behavioural, sexual, and psychological questions, and (2) HIV and STI counselling and testing. Some participants will be offered an additional, optional, one-time clinical assessment of their mental health.

Participants of the Engage Toronto Study will be characterized by the following eligibility criteria:

• Gender-identify as men, including men who identify on the trans-masculine spectrum
• Report sexual activity with a man in the previous six months
• Have received a recruitment voucher for participation in the study, or was purposively invited to be an initial “seed”
• Have the ability to provide informed consent and complete a computer questionnaire in English
• Be 16 years of age or older
