本研究以五次的實證研究來探索與驗證網路使用者使用線上社交網站的因素,藉由實證一進行43位使用者的深度訪談及實證二535份的紙筆問卷,再以實證三193份的線上調查問卷,提出七個使用線上社交網站的因素,這七個因素分別為:關係維持、拓展社交網路、尋求人氣、抒發情緒、獲取資訊、娛樂與消磨時間。根據前三次的實證研究,本研究提出一個包含21題問卷題項的社交網站使用量表,來衡量網路使用者使用線上社交網站的使用。實證四進行一個242位受訪者的線上問卷調查,以了解社會臨場感與知覺互補性對於Facebook社交網站使用之影響。結果顯示,社會臨場感的程度對於關係維持、拓展社交網路、尋求人氣、抒發情緒與消磨時間有影響。而知覺互補性對於拓展社交網路、獲取資訊、娛樂與消磨時間有影響。最後,實證五進行281份的紙筆問卷調查分析,透過多重特質多重方法矩陣(MTMM)分析五大人格量表、Facebook七個使用因素之強制排序法與李克特量表兩個統計方法的相關係數比較,以驗證七個使用Facebook因素的適當性。經過五次的實證研究,本研究所發展之線上社交網站使用因素量表具有高度的信效度。
