Clinical Trial Summary

Gay, bisexual, queer, and other men who have sex with men (GBM) continue to bear a disproportionate burden of the sexually transmitted and blood-borne infections (STBBI), largely attributable to efficient transmission during condomless anal sex (CAS). In 2020, GBM accounted for 46.6% of new HIV diagnoses in Canada. Incidence of syphilis, chlamydia and gonorrhea have risen among men who have sex with men (MSM), especially among HIV+ GBM living in Canadian urban centres, including Toronto. Post-traumatic stress disorder prevalence is also higher among GBM than among heterosexual men. Post-traumatic stress disorder (PTSD) is a risk factor for CAS and related STBBI among GBM. Despite the strong association between PTSD and STBBI risk among GBM, no studies have examined the efficacy of PTSD treatment on STBBI risk among GBM. PTSD is highly treatable via cognitive-behavioural therapies, including by Cognitive Processing Therapy. The present study will provide preliminary feasibility and acceptability data for a novel and innovative STI/HIV prevention intervention for GBQM. This intervention builds upon empirically supported treatments for PTSD, including PTSD-related substance use, by adding risk reduction counselling to reduce sexually transmitted infections (STI) and HIV sexual risk behaviour. The present study will provide trial data for a novel and innovative STBBI prevention psychotherapy for GBM that could be administered by mental health providers across Canada. The intervention will consist of 15 1-hour sessions of an integrated cognitive-behavioural approach using Cognitive Processing Therapy (CPT) to treat PTSD and to reduce STBBI risks among GBQM. The primary outcome will be condomless anal sex with casual partners. The secondary outcomes will be PTSD prevalence, trauma symptoms, problematic substance use, and PTSD-related avoidance of negative thoughts and feelings. This psychotherapy intervention will build upon empirically supported interventions to reduce HIV risk
