Participants attend 4 assessment sessions, during which they complete a series of interviews and questionnaires regarding social anxiety, substance use, and sexual risk behaviours. Participants also attend 10 sessions of counselling, where a therapist seeks to help the participant work towards reducing his anxiety in social and sexual situations and try to better manage his use of alcohol and drugs in sexual situations. The participant undergoes a baseline assessment, followed by 10 weekly counselling sessions, a post-treatment assessment, and 3- and 6-month follow-up assessments.
