Hi, friend! I get a question about Internet-based interventions for sexual health promotion. You may also be aware that men who meet other men through the use of the Internet are more likely to practice unprotected anal intercourse. Therefore, health promoters are increasingly supplementing traditional forms of face-to-face health education with Internet-based HIV-prevention interventions that aim to change both individual behaviors and community attitudes towards sexual health and condom use. However, I found that program evaluation of the effectiveness of such intervention is still very rare. Could you kindly help me with it?
