社交媒體vs.線上遊戲：台灣成人網路使用、媒介慣習與人際互動

Social Network Sites Versus Online Games: Internet Use, Media Habits, and Offline Interaction among Taiwanese Adults

使用傳播資料庫一期一次資料，本研究提出一理論模型檢驗台灣成人的網路使用。立基問題網路使用理論架構，並加入網路慣習，作者探討個人差異對於不同網路活動及後續線下人際互動的影響。結構方程式模型及中介分析顯示，網路使用慣習是三大個人因素中，預測網路活動最強的因素。社交網站頻率正向預測面對面互動的頻率，符合社會增加假說；線上遊戲使用頻率則不會增加面對面互動頻率，導致親友對其上網時間的抱怨，支持社會替代假說。

This study investigated Internet use among Taiwanese adults by using data from the National Communication Database. Employing a theoretical framework of problematic Internet use and media habits, social augmentation, and social displacement hypotheses, the author examined the relationship between individual differences, habits, and online activities, and their impact on offline face-to-face interaction. Results from structural equation models and bootstrapped mediational analyses indicated that a) strong preferences for online interaction, b) using the Internet when feeling lonely and, c) using the Internet habitually are critical factors that predict subsequent online activities. Among these factors, habitual Internet use exerted the strongest predictive power. Among online activities, the frequency of social network site use positively predicted the frequency of face-to-face personal interaction. By contrast, the frequency of online game play did not increase offline social interaction and elicited complaints from family and friends.
