本研究之主要目的在於探討當前澳門中學生之互聯網使用狀況、網絡成癮狀況、學習適應狀況及自我價值狀況;比較不同背景變項之中學生在網路成癮、學 習適應、自我價值之間的差異狀況;探討學習適應、自我價值與網路成癮之間的 關係。 本研究採用問卷調查法，以澳門地區392名中學生為研究對象，經施以自編的「網路使用狀況調查表」、「網路成癮量表」、「學習適應量表」、「自我價值量表」，並且以敘述性統計、t檢定、單因子變異數分析、卡方檢定、皮爾森 積差相關進行資料分析。 本研究之主要發現如下: 1.澳門中學生最主要的上網形式(2011)，主要集中在使用個人電腦(54.2%)和家中的共用電腦(36.1%)。在上網時間方面，最多學生每天上網2至3小時(38.4%)，其次是每天上網3至4小時(26.6%)。澳門中學生主要的網絡使用行為是使用社交網站(67.6%)，其次是聊天(60.70%)、聽音樂(45.40%)、玩網絡遊戲(42.30%)、看電影(33.9%)、查找資料(32.9%)等。 2.澳門中學生網絡成癮傾向不高；澳門中學生網絡成癮率為21.68%。不同性別、年級、上網時間在網路成癮上有顯著差異。高危群學生與一般學生在「每天上網平均時間」上有顯著差異，而在「性別」、「年級」、「上網形式」和不同的「學校類別」上無差異。高危群的中學生較會發生「收發電子郵件」、「瀏覽色情網站」、「網上投注博彩」等網絡使用行為。高危群學生與一般學生在網路成癮、學習適應上有差異，而在自我價值上無差異。不同學校類別在學習適應上有顯著差異，呈公立學校得分較低;不同性別在自我價值上有顯著差異，呈女生自我價值較高。 3.學習適應與網路成癮呈顯著負相關，學習適應越差網絡成癮就越嚴重。自我價值與網路成癮呈顯著正相關，自我價值越高網絡成癮亦越嚴重。 關鍵詞: 中學生、網絡使用行為、網絡成癮、學習適應、自我價值
