Computer-based interventions focused on decreasing sexually transmitted infections (STIs) provide participants with information on health issues of interest as well as computer-mediated decision making, behavior change, and emotional support. These interactive programs incorporate contributions from users to produce tailored material and feedback that is personally relevant. Programs may be delivered on personal computers or over the internet.
There is strong evidence that computer-based interventions increase knowledge about HIV and other sexually transmitted infections (STIs), self-efficacy, and safe-sex intentions among adults and adolescents (Guse 2012, Noar 2010, Cochrane-Bailey 2010). These inventions have also been shown to increase condom use and decrease the number of sexual partners (Noar 2009).
Among adolescents, computer-based interventions may also delay initiation of sex and increase pregnancy prevention knowledge (Guse 2012), however, additional evidence is needed to confirm these effects.
Interventions that are tailored to individual users tend to be most successful (Noar 2009, Noar 2010, Cochrane-Bailey 2010). Provision of individualized feedback, promotion of active learning, anonymity, and repeatability are also frequently components of effective computer-based interventions (Cochrane-Bailey 2010).
Computer-based interventions can be easily disseminated and can be relatively inexpensive (Cochrane-Bailey 2010).
Positive Choices is an example of a successful computer-based intervention that implements tailoring (CDC-Positive Choice).
