Gender differences in social network development via mobile phone text messages: A longitudinal study

We examined the development of face-to-face (FTF) social networks and mobile/cell phone text message (MPTM)-mediated social networks, and gender differences in the social network structure of 64 male and 68 female first-year undergraduate students. Social network analysis showed that MPTM social networks consisted of dyadic relationships, and its growth was slower than FTF social networks. The intimacy of friends who communicate via both FTF and MPTM was rated higher than those who communicate only via FTF. The structure of MPTM social networks coincided with known gender differences in network characteristics. Females tended to expand their MPTM social networks more than males. These findings suggest that patterns of interpersonal relationships for MPTM social networks corresponded to Matsuda's (2000) selective interpersonal relationship theory.
