Abstract
Objective
To examine the long-term efficacy of both fear-inducing arguments and HIV counseling and testing at encouraging and maintaining knowledge about HIV transmission and prevention, as well as condom use.
Design
Analyses were conducted with a sample of 150 treatment groups and 34 controls and included measures of change at an immediate follow-up and a delayed follow-up.
Main outcome measures
The main outcome measures were perceived risk of HIV infection, knowledge about HIV, and condom use.
Results
Results indicated that receiving fear-inducing arguments increased perceptions of risk at the immediate follow-up but decreased knowledge and condom use, whereas resolving fear via HIV counseling and testing decreased perceptions of risk and increased knowledge and condom use at both the immediate and delayed follow-ups. The effects on perceived risk and knowledge decreased over time, but the effects on condom use became more pronounced.
Conclusion
Inducing fear is not an effective way to promote HIV-relevant learning or condom use either immediately following the intervention or later on. However, HIV counseling and testing can provide an outlet for HIV-related anxiety and, subsequently, gains in both knowledge and behavior change immediately and longitudinally.
