The theory of media effect can be divided into channel choice and media usage(Brandtzæg, 2010). The mix of media channels are posited to affect individuals’ media usesand their relationships (Haythornthwaite, 2005; Meng, Williams, & Shen, 2015). Comparedwith face-to-face communication, individuals can communicate via computer-mediatedcommunication in different time and space, which is assumed to affect interpersonalrelationships generated online and offline (Parks & Roberts, 1998; Walther, 1992; Walther& Parks, 2002). Meanwhile, the choice of communication medium should be determinedby both senders and recipients (Table 1) and is regarded to affect their relational behaviorand level of closeness/or intimacy (Ledbetter, Taylor, & Mazer, 2016; Ramirez & Broneck,2009).
