高中生Instagram持續使用意圖之研究

Continuance Intention of Using Instagram among High School Students

本研究以資訊系統持續使用模式為基礎，結合知覺有趣性、隱私機制及信任來探討高中（職）生Instagram之持續使用意圖。研究結果顯示：使用者之確認對知覺有用性、知覺有趣性有正向顯著影響；使用者之確認、知覺有用性、知覺有趣性及信任對滿意度有正向顯著影響，其中信任對於滿意度之直接影響效果最大；使用者之知覺有用性、知覺有趣性及滿意度對持續使用意圖有正向顯著影響，其中滿意度對於持續使用意圖之直接影響效果最大；隱私機制對信任有正向顯著影響；信任對持續使用意圖雖無顯著影響，但會透過滿意度間接影響持續使用意圖。 The study is based on Information Systems Continuance Model and combines with perceived enjoyment, privacy mechanism, and trust to investigate continuance intention of using Instagram among high school students.
