EFFECTS OF INTERNET USE AND SOCIAL RESOURCES ON CHANGES IN DEPRESSION

We examine how people's different uses of the Internet predict their later scores on a standard measure of depression, and how their existing social resources moderate these effects. In a longitudinal US survey conducted in 2001 and 2002, almost all respondents reported using the Internet for information, and entertainment and escape; these uses of the Internet had no impact on changes in respondents' level of depression. Almost all respondents also used the Internet for communicating with friends and family, and they showed lower depression scores six months later. Only about 20 percent of this sample reported using the Internet to meet new people and talk in online groups. Doing so changed their depression scores depending on their initial levels of social support. Those having high or medium levels of social support showed higher depression scores; those with low levels of social support did not experience these increases in depression. Our results suggest that individual differences in social resources and people's choices of how they use the Internet may account for the different outcomes reported in the literature.     

Communicating Global Activism

Many observers doubt the capacity of digital media to change the political game. The rise of a transnational activism that is aimed beyond states and directly at corporations, trade and development regimes offers a fruitful area for understanding how communication practices can help create a new politics. The Internet is implicated in the new global activism far beyond merely reducing the costs of communication, or transcending the geographical and temporal barriers associated with other communication media. Various uses of the Internet and digital media facilitate the loosely structured networks, the weak identity ties, and the patterns of issue and demonstration organizing that define a new global protest politics. Analysis of various cases shows how digital network configurations can facilitate: permanent campaigns; the growth of broad networks despite relatively weak social identity and ideology ties; transformation of individual member organizations and whole networks; and the capacity to communicate messages from desktops to television screens. The same qualities that make these communication-based politics durable also make them vulnerable to problems of control, decision-making and collective identity.

Health Information Seals of Approval: What do they Signify?

Much of the health information available to consumers on the Internet is incomplete, out of date and even inaccurate. Seals of approval or trustmarks have been suggested as a strategy to assist consumers in identifying high-quality information. Little is known, however, about how consumers interpret such seals. This study addresses this issue by examining assumptions about the quality criteria that are reflected by a seal of approval. This question is of particular importance because a wide variety of quality criteria have been suggested for online health information, including: core aspects of quality such as accuracy, currency and completeness; proxy indicators of quality such as the disclosure of commercial interests; and indicators that reflect the quality of the site or the interaction it affords, such as the availability of a search mechanism. The results of this study suggest that seals of approval are assumed to certify information quality primarily with respect to core quality indicators, aspects that subjects both consider to be important and feel relatively less able to evaluate for themselves (compared with their ability to rate proxy indicators of information or indicators of site or interaction quality). This assumption is largely inconsistent with practice: most seals of approval involve assessment of proxy indicators of information quality, rather than direct assessment of content. These results identify a problem that certification or accreditation bodies must address since, unless and until consumer expectations are congruent with evaluation practice, seals of approval will seem to promise more than they deliver.
