Current trends in Internet- and cell phone-based HIV prevention and intervention programs

Ybarra ML, Bull SS. Current trends in Internet- and cell phone-based HIV prevention and intervention programs. Curr HIV/AIDS Rep. 2007;4(4):201-7.

To identify recent advances in technology-based HIV prevention and intervention research, we conducted a literature search in the Spring of 2007. Only a handful of articles have been published in the last year describing evaluations of technology-based HIV programs. Nonetheless, many programs have recently been funded and are being developed or imminently evaluated. Results to date suggest the Internet and cell phones are feasible technologies to deliver HIV prevention and intervention … [Read more...]

Wolak J, Ybarra ML, Mitchell KJ, Finkelhor D. (2007). Current research knowledge about adolescent victimization via the Internet. Adolesc Med State Art Rev. 2007;18(2):325-341.

Internet-initiated sex crimes have received considerable publicity, but the media stories have contributed to stereotypes that do not accurately portray adolescent Internet experience. Adults’ concerns are valid but need to be supported with information that illuminates the real safety issues and targets the specific … [Read more...]
