Differences between Internet samples and conventional samples of men who have sex with men: implications for research and HIV interventions

The Internet is becoming a new erotic oasis for obtaining sex online or in person. We reviewed the literature on cybersex and compared differences in data from samples of homosexually active men obtained on identical questionnaires from a conventional written questionnaire, distributed through the mailing and contact lists of a large national gay organization in Sweden, and through the same organization's website and chat room. A total of 716 written questionnaires and 678 Internet questionnaires were obtained. The Internet sample was younger, more likely to live in small towns or cities, live with parents or a girlfriend, and have lower formal education. They are less likely to have previous sexual experience solely with other men (one in three of the Internet sample vs. 1 in 14 of the written sample defined themselves as bisexual) and more likely to visit erotic oases such as bathhouses, video clubs and erotic movie houses. They also visited Internet chat rooms more frequently (86% of the Internet sample vs. 50% of the written sample). One third of the Internet sample wanted the opportunity to talk with an expert about HIV compared with a quarter of the written sample. Sexual practices between the two samples were generally similar, although the Internet sample reported significantly less body contact, kissing, hugging, mutual masturbation, and more condom use for anal intercourse with steady partners. Over four times as many of the Internet samples reported sex with women in the past year as the written sample. These data indicate that Internet data collection is feasible and that this mode of data collection, despite the nonrandom and self-selected nature of both types of samples, is likely to be more significantly oriented toward the young, geographically more isolated, and more behaviorally and self-identified bisexual respondent than conventionally distributed written questionnaires.

Health information, the Internet, and the digital divide

Through an analysis of recent data on adults' and children's computer use and experiences, this DataWatch shows that use of computers and the Internet is widespread and that significant percentages of the public are already using the Internet to get health information. The surveys also show that the Internet is already a useful vehicle for reaching large numbers of lower-income, less-educated, and minority Americans. However, a substantial digital divide continues to characterize computer and Internet use, with lower-income blacks especially affected. Implications for the future of health communication on the Internet also are explored.     

Computer access and Internet use among urban youths

This report presents data on computer access, Internet use, and factors associated with health information seeking on the Internet among a sample of youths aged 15 to 30 years in New York City. Findings from street intercept surveys indicate substantial computer access at home (62%) and frequent (everyday or a few times a week) Internet use (66%). Fifty-five percent of the sample reported seeking health information on the Internet, which was associated with positive beliefs about getting a health checkup and frequent Internet use.     

Unsolicited narratives from the Internet: a rich source of qualitative data

Recently, the Internet has become a forum for informal communication. Many--whose voices may have been unheard--can now express themselves through this medium. Rich narratives are available to the qualitative researcher from bulletin boards, guestbooks, Web pages, and listservs on the Internet. In this article, these data sources are defined and described. Strategies for using these data are discussed. One concern with using unsolicited data from the Internet is the protection of human subjects and the requirement for consent. A proposed model describing the process for deciding when such data are publicly available, as defined by the Office for the Protection of Rights of Research Subjects, and when the use of the data requires consent is presented.     

Chronic illness and health-seeking information on the Internet

By using the theories of help-seeking behavior and health-information seeking, this article demonstrates the relationship between chronic illness, retrieving health information from the Internet and changing health behavior. Research on the impact of health information on the Internet and changing health behavior is fairly new, given the growth of the Internet in recent years. Using US data on Internet use within the US population, multiple regression analysis was performed to explore the relationships between chronic medical conditions and frequency of Internet use, as well as changes in health behavior due to frequency of Internet use. The findings suggest that it is not merely the presence of a particular chronic illness, but rather the total number of chronic conditions that determine Internet use. Also, the more frequently a person uses the Internet as a source of health information, the more likely they are to change their health behavior.     

Incidental Health Information Use on the Internet

This study investigates the correlates of incidental or nonpurposive health information use on the Internet. Through a secondary analysis of the Health Information National Trends Survey II data, this study reveals that incidental health information use on the Internet is positively associated with overall Internet use, active health information seeking on the Internet, and incidental health information use from traditional media. Thus, this study extends the notion of media complementarity to incidental media usage in a health communication context. This study also reveals that adults who have been diagnosed with cancer are more likely to have incidental health information use from traditional media but not the Internet. More important, this study suggests that incidental health information use on the Internet is positively associated with health knowledge. The findings have important implications for health information campaigns on the Internet.     

Examining Factors Influencing Internet Addiction and Adolescent Risk Behaviors Among Excessive Internet Users

In China, public concern continues to mount regarding the risks of excessive Internet use among adolescents. This study investigated the factors influencing Internet addiction and adolescent risk behaviors among excessive Internet users. Proposing a conceptual model with a theoretical origin in risk behavior theory and media dependency theory, this study examined the influence of personality traits, online gaming, Internet connectedness (both the overall index and various scopes), and demographics on Internet addiction and risk behaviors (smoking, drinking, gambling, and risky sexual behaviors). Clinical data (N = 467) were retrieved from one of the earliest and largest Internet addiction clinics in China. The findings reveal that certain personality traits are significantly associated with Internet addiction and risk behaviors. Online gaming had a strong impact on both Internet addiction and risk behaviors among excessive Internet users. The study also reveals that various scopes of Internet connectedness, such as site scope, facilitate addictive Internet use, and risk behaviors among adolescents. The findings can contribute to the prevention of and intervention into Internet addiction and adolescent risk behaviors.
