Publicly Available Internet Content as a HIV/STI Prevention Intervention for Urban Youth.

Sexual and racial minority adolescents and young adults account for the most substantial number of new HIV infections in the United States. Numerous publicly available websites and YouTube videos contain HIV/STI prevention information that is culturally tailored to racial and ethnic minorities, and gay and bisexual youth. However, the effect of this easily accessible Internet content on adolescent and young adult HIV/STI related knowledge, attitudes and behaviors is unknown. We assembled a HIV/STI Internet intervention from publicly available online sources, including YouTube and privately and publicly hosted websites. We tested the preliminary efficacy of this internet intervention by means of a randomized controlled pilot study with 60 diverse adolescents and young adults recruited in Providence, RI (mean age 18.6 years, 62% male, 52% Black/African American, 36% Hispanic, 47% non-heterosexual). Youth who received links to publicly accessible online prevention content by email had a significant improvement in HIV self-efficacy (p < .05) and a significant reduction in unprotected vaginal or anal sex (12.5 vs. 47.6%, AOR = 7.77, p < .05), as compared to a control group who did not receive the internet content by email. If these preliminary findings can be confirmed by future research, free online content could be inexpensively distributed to at risk youth in underserved communities and could hold promise as an inexpensive method of HIV/STI prevention.

Eliciting affect via immersive virtual reality: a tool for adolescent risk reduction.

OBJECTIVE: A virtual reality environment (VRE) was designed to expose participants to substance use and sexual risk-taking cues to examine the utility of VR in eliciting adolescent physiological arousal. METHODS: 42 adolescents (55% male) with a mean age of 14.54 years (SD = 1.13) participated. Physiological arousal was examined through heart rate (HR), respiratory sinus arrhythmia (RSA), and self-reported somatic arousal. A within-subject design (neutral VRE, VR party, and neutral VRE) was utilized to examine changes in arousal. RESULTS: The VR party demonstrated an increase in physiological arousal relative to a neutral VRE. Examination of individual segments of the party (e.g., orientation, substance use, and sexual risk) demonstrated that HR was significantly elevated across all segments, whereas only the orientation and sexual risk segments demonstrated significant impact on RSA. CONCLUSIONS: This study provides preliminary evidence that VREs can be used to generate physiological arousal in response to substance use and sexual risk cues.
