Although the Internet is commonly used by lesbian, gay, bisexual, and transgender (LGBT) youth to explore aspects of sexual health, little is known about how this usage relates to offline explorations and experiences. This study used a mixed-methods approach to investigate the interplay between online and offline explorations of multiple dimensions of sexual health, which include sexually transmitted infections, sexual identities, romantic relationships, and sexual behaviors. A diverse community sample of 32 LGBT youth (ages 16-24) completed semi-structured interviews, which were transcribed and then qualitatively coded to identify themes. Results indicated that, although many participants evaluated online sexual health resources with caution, they frequently used the Internet to compensate for perceived limitations in offline resources and relationships. Some participants turned to the Internet to find friends and romantic partners, citing the relative difficulty of establishing offline contact with LGBT peers. Further, participants perceived the Internet as an efficient way to discover offline LGBT events and services relevant to sexual health. These results suggest that LGBT youth are motivated to fill gaps in their offline sexual health resources (e.g., books and personal communications) with online information. The Internet is a setting that can be harnessed to provide support for the successful development of sexual health.

The current study used a mixed-methods approach to investigate the positive and negative aspects of Internet use for sexual health information among lesbian, gay, bisexual, and transgender (LGBT) young people. A diverse community sample of 32 LGBT young people (aged 16-24 years) completed qualitative interviews focusing on how, where, and when LGBT young people use the Internet for sexual health information. Results indicate that although many participants seek facts and statistics about sexually transmitted infections (STIs) and HIV online, few conduct searches about broader aspects of sexual health. Participants reported that fear about becoming infected with STIs/HIV is a common motivator of searches and noted a number of reasons for not using online sexual health information, including stigma associated with being observed accessing LGBT or HIV information. Together, the results revealed not only significant interest in online sexual health information but also concerns about the perceived limitations of this promising method of sexual health promotion.

HIV+ substance dependent individuals (SDIs) make significantly poorer decisions compared with HIV− SDIs, but the neurocognitive mechanisms underlying this impairment have not been identified. We administered the Iowa Gambling Task, a measure of decision making under uncertain risk, and the Cups Task, a measure of decision making under specified risk, to a group of 56 HIV+ and 23 HIV− men who have sex with men (MSMs) with a history of substance dependence enrolled in the Multicenter AIDS Cohort Study. The IGT provides no explicit information regarding the contingencies for each possible choice, and the probability of each outcome remains ambiguous at least for the early trials; in contrast, the Cups Task provides explicit information about the probability of each outcome. The HIV+ group made significantly poorer decisions on the IGT compared with the HIV− group. Cups Task performance did not differ significantly between HIV− and HIV+ groups. Exploratory analyses of the IGT data suggested that HIV+ subjects tended to perform more poorly during the early learning phase when uncertainty about specific outcomes was greatest. Additionally, performance on the final two trial blocks was significantly correlated with Stroop Interference scores, suggesting IGT performance is driven increasingly by executive control during the later portion of the task. Potential cognitive mechanisms to be explored in later studies are discussed, including impairment in implicit learning processing
