網路霸凌目前在少年之間逐漸流行，少年網路被害事件也逐漸增多。過去對 網路霸凌的實證研究中指出被害者之日常生活方式與其遭遇被害有關聯，不過多 半是對網路霸凌的現象面作探討，無法對網路霸凌和日常活動理論的關聯作更深 入研究。為了彌補這個缺口，本研究即嘗試以日常活動理論的三要素：「潛在的 加害者」、「適合的標的物」、「具有能力的監控者不在」，試圖了解網路霸凌的被 害因素，並質性研究取向，在現象學的觀點下進行探索性研究，針對事件的被害 者、加害者、未成年旁觀者與成年監控者，共收集了十三份文本進行分析。 本研究發現網路霸凌起源於現實生活中的紛爭，被害者與加害者習慣使用網 路溝通選項來發展社交關係與解決衝突。加害者經過理性選擇後進行霸凌，但是 沒有顧慮到行為後果。部分加害者利用網路的匿名性與便利性，掩飾身分與隨時 隨地騷擾被害者。加害者利用網路所散佈的訊息，可能引發網路上不特定多數之 人幫助參與霸凌。網路的高私密性使監控者無法在第一時間處理霸凌，所以對少 年網路正當使用的教育與輔導也就更形重要。最後歸納出日常活動理論在解釋網 路霸凌被害因素時的合適度與侷限，並對防治網路霸凌提出具體的建議，作為預 防網路霸凌時的參考。
