本研究重點欲探討時下人人皆有的心理狀態「寂寞感」、「交友軟體的使用動機」與「自我揭露」行為之間的關係、而「交友軟體品質特性」又如何調節影響「交友軟體使用動機」與「自我揭露」行為。本研究採取網路問卷調查的方式，對於交友App有使用經驗的使用者為主要調查對象，共計307有效問卷進行分析。本研究主要發現如下： 1.本研究的受試者以男性、年齡18-25歲、學歷以大專院校者為最多，感情狀況以未婚族群最多，但是還是有非單身甚至已婚交友用戶；使用交友軟體的時間大多兩年之內，平均下載2.66個交友App軟體，其中最常使用的交友App軟體為Beetalk。受試者平均每週上交友軟體的天數為5.07天，每週花費5.43小時。另外，高達94.1%的受試者曾經在交友App平台上與陌生人進一步用其他通訊軟體、社群媒體互動，並有88.9%的受試者曾約現實碰面。 2.寂寞感程度可顯著的正向預測交友軟體使用動機中的日常社交、社會逃避以及尋愛之三個構面。 3.寂寞感程度可顯著的正向預測自我揭露中的誠實度、數量以及正負向之三個構面。 4.關於交友軟體使用動機(日常社交、社會逃避、尋愛)與自我揭露(誠實度、數量、正負向)之間的關係：交友軟體使用動機中日常社交、社會逃避與尋愛之三個構面皆可顯著預測自我揭露中的誠實度：當日常社交和社會逃避動機越高時，自我揭露中的誠實度越高；但是當尋愛動機越高時，自我揭露中的誠實度越低。交友使用動機中日常社交和尋愛之二個構面皆可顯著預測自我揭露中的數量：當日常社交動機越高時，自我揭露中的數量越高；但當尋愛動機越高時，自我揭露中的數量越低。交友使用動機中日常社交之構面可顯著正向預測自我揭露中的正負向。 5.交友軟體品質特性(使用者介面、安全性、形象聲譽、會員素質、尋愛達成率)對交友軟體使用動機與自我揭露的調節效果中，僅只有尋愛達成率對交友軟體使用動機和自我揭露產生調節效果。 6.交友軟體使用動機中僅有日常社交之構面對於寂寞感程度與自我揭露有中介效果。 / The purpose of this study is to explore how “loneliness” which is widely prevalent throughout the society affects the motives of using online dating applications and the behavior of self-disclosure.
