人际关系的建构和维持是人社会性发展的核心内容之一。而对于始成年人来说，朋友关系对其独立性发展、身份识别以及冲突解决能力都能产生深远影响。而随着互联网的普及，始成年人也更多地使用计算机媒介，尤其是社交网站来进行社会化。在个体人际关系构建的过程中，人格特质是非常重要的因素。基于此，本研究试图通过3个子研究，从关系发展和社会网络演化的角度，从现实生活与在线社交网站的角度来探讨人格及其相似性如何影响始成年人的友谊。
本研究选取四个班共166名大一新生。在1学年的时间内完成3次测试。测量工具为John and Srivastava（1999）的大五人格量表，使用循环设计测量个体与班级各个成员的在现实生活中与在线社交网站上的沟通频率。
研究一采用阶层线性模型考察人格对个体自身及关系另一方构建初识友谊与友谊发展的影响。结果发现尽责性的二次项和外向性对沟通频率的起点有正向的预测；宜人性、尽责性和神经质的二次项对关系发展的速率存在显著负向的预测。研究二从社会网络视角考察个体人格对现实友谊质量的影响。结果发现外向性存在积极的选择效应，开放性上存在消极的选择效应；外向性、尽责性存在消极的被选择效应，宜人性、开放性存在积极的被选择效应；外向性、宜人性和开放性上存在相似性选择。研究三从社会网络视角考察个体人格对在线社交网站友谊质量的影响。结果发现宜人性、尽责性、神经质存在积极的选择效应，开放性上存在消极的选择效应；外向性、尽责性存在消极的被选择效应，开放性存在积极的被选择效应。
研究结论：在个体初识以及友谊发展的过程中，人格的作用不尽相同。而人格对于现实线上友谊建立的影响是不一致的。
