 Reviews of the literature have suggested that there have been 3 basic approaches to the design of HIVSTI risk reduction programs aimed at MSM. One approach is to seek to reduce risk through the implementation of small group or workshop interventions. The second approach is through the use of community-level interventions. A third approach is the individual one-on-one intervention. All three approaches have merit and have reduced risk behavior among men in controlled trials. An advantage of the one-on-one is that it avoids the problem of men having to risk revealing that they have sex with other men in order to participate in the prevention program. There are added benefits of the one-on-one approach. It permits tailoring the intervention to the specific needs of the man. A recent meta-analysis has identified characteristics of effective HIV behavioral interventions for MSM. Efficacy was associated with interventions having more than one session, duration of 4 or more hours, and a time span of at least 3 weeks.
