Young MSM are at increased risk for HIV, especially in the context of
serious relationships, but there is a lack of couples-based HIV prevention for
this population. The 2GETHER intervention—an HIV prevention and
relationship education program for young male couples—demonstrated
promising effects in a pilot trial. However, there is evidence that internalized
stigma (IS) can influence treatment outcomes among MSM. The current study
examined the influence of IS on the efficacy of the 2GETHER intervention among
57 young male couples. The intervention led to decreases in percentage of
condomless anal sex partners and increases in subjective norms regarding HIV
prevention for those with low/average IS, but not high IS. The intervention also
led to increases in motivation to get tested with one’s partner and
decreases in alcohol consumption for those with high IS, but not low/average IS.
In contrast, IS did not moderate intervention effects on other motivational
constructs, dyadic adjustment, or alcohol problems. In sum, IS influences the
extent to which young male couples benefit from HIV prevention and relationship
education, depending on the outcome. Research is needed to understand how IS
influences treatment outcomes.
