Pilot Randomized Trial of an Expressive Writing Intervention to Reduce Sexual HIV-Transmission Risk and Substance Use Among Emerging Adult Gay and Bisexual Men.

This pilot randomized controlled trial evaluated the feasibility, acceptability, and preliminary efficacy of expressive writing to reduce HIV-related sexual risk taking and symptoms of drug dependence among emerging adult gay and bisexual men (EAGBM) through linguistic mechanisms involving use of words associated with cognitive processing (e.g., think, cause), positive emotion (e.g., love, nice), and negative emotion (e.g., hurt, shame). Between 2014 and 2015, EAGBM (n = 78; aged 18-29) completed a baseline survey and were randomized to complete three 15-min expressive writing or equivalent control-group writing sessions and follow-up assessments 2 months post-baseline. EAGBM in the expressive writing condition utilized significantly more positive emotion, negative emotion, and cognitive processing words. Path model results indicated the intervention condition resulted in significant reductions in symptoms of drug dependence and frequency of condomless anal sex (CAS) through paths mediated by positive emotion words, and significant increases in CAS through a path mediated by negative emotion words.
