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. Abstract: As the reach of the Internet and cell phones increases, their use as health intervention and prevention tools has been increasingly researched. 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...]

Mitchell KJ, Ybarra ML, Finkelhor D. The relative importance of online victimization in understanding depression, delinquency and substance use. Child Maltreat. 2007;12(4):314-324.

Nearly three fourths (73%) of youth reporting an online victimization also reported an offline victimization. Virtually all types of online and offline … [Read more...]

All youth were equally … [Read more...]
Current research knowledge about adolescent victimization via the Internet
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. Abstract: We review current knowledge about adolescent Internet-mediated victimization, including Internet-initiated sex crimes in which offenders use the Internet to meet victims, unwanted online sexual solicitations, Internet harassment, and unwanted and wanted exposure to online pornography. 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...]
Health information seeking among Mbararan adolescents: results from the Uganda Media and You survey
Ybarra ML, Emenyonu N, Nansera D, Kiwanuka J, Bangsberg DR. Health information seeking among Mbararan adolescents: results from the Uganda Media and You survey. Health Educ Res. 2008;23(2):249-258. doi: 10.1093/her/cym026 Abstract: To maximize scarce intervention dollars, pediatricians and other adolescent health professionals must position health promotion efforts in mediums that most effectively reach youth. This may be especially true in resource-limited settings where access to primary health care and medications is limited. To improve the efficiency and impact of disease prevention and health promotion efforts in resource-limited settings, we examine sources of health information cited by adolescents in Mbarara Uganda. Participants in the Uganda Media and You survey were students … [Read more...]

The feasibility and accessibility of Internet-based health interventions in resource-limited settings, where cost-effective interventions are most needed, is unknown. To determine the utility of developing technology-based interventions in resource-limited settings, availability and patterns of usage of the Internet first need to be assessed.
