Lurking as an active participation process: a longitudinal investigation of engagement with an online cancer support group.

To better understand participation in computer-mediated social support (CMSS) groups for breast cancer patients, this study examines two overarching questions of (1) who are posters, lurkers, or nonusers and (2) what role do these different types of engagement play in explaining psychosocial health outcomes? This study incorporates the comprehensive model of information seeking and two competing models of social enhancement and social compensation, as well as the literature on lurking and posting behaviors in online groups to answer research questions. Our findings suggest that patterns of engagement in a CMSS group differed according to patients' sociodemographic characteristics and psychosocial factors. In addition, we found that lurkers had a higher level of perceived functional well-being than posters at 3 months post baseline.

The role of provider-patient communication and trust in online sources in Internet use for health-related activities.

Provider-patient communication is an important factor influencing patients' satisfaction and health outcomes. This study draws upon the uses and gratification theory to examine how individuals' perception of communication with healthcare providers is associated with their Internet use for health-related activities. Using the data from the 2007 Health Information National Trends Survey (HINTS), we found that as individuals perceived their communication with providers to be less patient-centered, they were more likely to engage in various types of online health activities, such as using websites for healthy lifestyles, searching for healthcare providers, and seeking health information.
