“…In 3D virtual communities, users' identification with and social attraction to the community, also influenced the subsequent sustained use of virtual services (Kim, Lee, & Kang, 2012;Zhang, Ordóñez de Pablos, et al, 2014;Zhang, Zhang, et al, 2014;Zhou, Fang, Vogel, Jin, & Zhang, 2012), Additionally, various indicators of online popularity on SNS profile pages (e.g., number and physical attractiveness of friends) have also been found to influence interpersonal attraction and willingness to develop online friendships (Henderson & Gilding, 2004;Sheer, 2011;Tong et al, 2008;Wang, Walther, & Hancock, 2009). Studies assessing SNSs for dissemination of health messages have also found that active SNS use led to greater behavioral intention, behavioral beliefs, attitude change, and self-efficacy for prevention of health issues such as STDs (Jones, Eathington, Baldwin, & Sipsma, 2014), smoking (Phua, 2013), and anorexia (Syed-Abdul et al, 2013). Further, research has found that active participants in online health com- munities showed greater levels of empathy with other members (Pfeil & Zaphiris, 2007) and increased altruistic sharing (Civan & Pratt, 2007).…”
