Elaborating Cancer Opinion Leaders’ Communication Behaviors Within Online Health Communities: Network and Content Analyses

Abstract

This study integrates social network and content analyses to examine the communication behaviors of opinion leaders—such as creating threads and engaging in continuous conversations—in two large cancer-focused online health communities. Guided by the diffusion of innovation theory and the social support literature, we analyzed 951 threads and 10,179 posts and found that a group of opinion leaders (including cancer patients, family caregivers, and cancer survivors) centralized the communities from 2017 to 2018. Opinion leaders’ typical replies to others tended to be a combination of opinion support, emotional support, and network support. Amid their self-created threads, we further identified four themes: cancer history and treatment, health or life condition update, advocacy, and emotional ventilation. Implications for network and content analytics of online cancer communication are discussed.
