Computer-mediated communication (CMC) has been increasingly applied in health communication to provide interventions and education. A key question confronting health communication research is the effects of new technology on health communication. Despite the advantages of computer-mediated health communication (CMHC), the overall results of computer-mediated health interventions are mixed. To provide insights to CMHC scholars and generate cumulative knowledge, the current dissertation project consists of three meta-analytical reviews under the umbrella of CMHC. Specifically, three studies analyzed the general effectiveness of social-mediabased health intervention, online support groups, and online interactive health interventions. Moreover, a series of moderator analyses were conducted to identify the variables that moderate the general effects of these three types of online health interventions. The identification of moderators will inform health communication scholars and practitioners in designing online health interventions.
