About The Study

This study will examine the effectiveness of using CBT combined with HIV risk reduction counselling to simultaneously treat social anxiety disorder, substance use disorders, and HIV sexual risk behaviour. The researchers will compare this intervention with applied relaxation – a behavioural intervention that can effectively treat social anxiety disorder but does not focus on substance use or HIV sexual risk behaviours. If successful, the study will provide data for new and innovative HIV prevention strategies for gbMSM.

About The Disease

In Canada, sexually transmitted infections (STIs) and HIV disproportionately affect gay, bisexual, and other men who have sex with men (gbMSM). It is thought that this is largely due to efficient transmission of infections during condomless anal sex (CAS). Research suggests that CAS between gbMSM may be linked to social anxiety, which is anxiety in social situations. Social anxiety may in turn increase the likelihood of substance use in sexual situations, which carries its own risk for HIV transmission.

High social anxiety can be treated using cognitive behavioural therapy (CBT) and applied relaxation. However, to date, only one small study has examined the effectiveness of social anxiety treatment on CAS among gbMSM.

Study Approach

This study will aim to recruit 44 participants per year, to reach a total of 176 HIV-negative gbMSM over a four-year period. The participants will be randomized to either 12 sessions of CBT or 12 sessions of applied relaxation. Assessments will take place at baseline, following the intervention sessions, and three and six months after the intervention. The assessments will include interviews, laboratory testing, and self-reported measures of social anxiety, substance use in sexual situations, and sexual risk behaviours.
