Men who have sex with men (MSM) are the key population most
affected by HIV in Europe. We performed the first European multicenter,
simple-randomized parallel-group study to test the effectiveness of a
theory-guided computer-assisted intervention to improve safer sex among
HIV-positive MSM.
Between 02/2011-02/2013, 112 participants were enrolled in
eight different European HIV care settings. Intervention participants received
three individual counseling sessions facilitated by trained service providers
using computer-assisted tools. The control-group received sexual health advice
delivered as part of regular HIV care. Outcome behavior (self-reported condom
use at last intercourse; combined HIV transmission risk score), its influencing
factors and mediating variables were assessed at baseline, and at three and six
months follow-up. Mixed effects models were used to compare primary outcomes
(condom-use at last intercourse, HIV transmission risk score), and mediation
analysis to explore intervention effects.
Condom-use at last intercourse increased more among
intervention- than control participants at three months follow-up (odds ratio
of 3.83; p=0.03), but not significantly at six months follow-up. Intervention
participants reported a lower transmission risk at three months follow-up than
controls (odds ratio compared to baseline of 11.53 and 1.28 respectively;
p=0.008) but this effect became nonsignificant at six months. Intervention
effects were mediated by the proximal variables self-efficacy to negotiate
condom-use and condom attitudes.
This intervention showed short-term effectiveness. The
intervention should be replicated in other settings, eventually investigating
if booster-counseling sessions would yield a longer lasting effect.
