The purpose of this study was two-fold. First, it examined the predictive power of HIV/AIDS-related knowledge, attitudes towards teaching about HIV/AIDS, support for AIDS education, AIDS teaching comfort, HIV/AIDS teaching behavioral control, religious and cultural beliefs about HIV/AIDS, subjective norms about teaching HIV/AIDS, and demographic factors on Haitian educators' reported HIV/AIDS teaching behavior. Second, it assessed the short-term effects of an HIV/AIDS teacher training offered to 214 teachers in Haiti. Results showed that the odds of teaching about HIV/AIDS were greater for those participants with higher perceived subjective norms and behavioral control and lower cultural and religious beliefs about HIV. The odds of teaching about HIV/AIDS were also higher for males and secondary teachers. Also, there was a significant increase in teachers' knowledge, teaching comfort, and perceived behavioral control about teaching HIV/AIDS after the intervention. Implications for future prevention interventions and research are discussed.
