Reinforcement or Displacement? The Reciprocity of FtF, IM, and SNS Communication and Their Effects on Loneliness and Life Satisfaction
基于德国纵向代表性样本，研究发现社交网站沟通会促进后续面对面和即时通讯沟通，且社交网站沟通能轻微提升生活满意度，但三种沟通方式均不影响孤独感。
Does communication on social network sites (SNSs) or instant messengers (IMs) reinforce or displace face-to-face (FtF) communication, and how do the 3 channels affect loneliness and life satisfaction? Using cross-lagged structural equation modeling in a longitudinal and representative sample from Germany, we found that SNS communication increased both FtF and IM communication 6 months later. Likewise, IM communication at T1 increased SNS communication at T2. FtF, SNS, and IM communication did not affect loneliness, and FtF and IM communication did not change life satisfaction. However, communication on SNSs slightly increased life satisfaction. Thus, the data indicated that conversing via SNSs and IM has a mainly reinforcing effect and that communicating via SNSs can enhance life satisfaction several months later.
