摘要
幫派問題一直是全民治安之一大隱憂，雖經警方多次大力掃蕩，但幫派問題仍然存在難以根除。幫派政策的擬定，對於幫派問題迄今未能有效防治，原因之一在於對幫派問題的瞭解不足。若從反向思考，欲對瓦解幫派進行研究，勢必要向幫派脫離成員學習，來分析警政、獄政、矯治單位該如何發揮社會、心理與經濟功能，滿足社會所未能滿足成員的個別需求。 參酌國內外文獻，本研究透過生命歷程觀點、差別接觸理論、理性選擇等理論來進行幫派脫離歷程之初探，企圖找出幫派脫離的關鍵因素，做為相關單位與幫派抗衡之措施。 為瞭解幫派脫離成員的歷程，本研究透過質性訪談的方式，以立意抽樣及半結構式訪談三名男性幫派脫離成員生命歷程之寶貴經驗，訪談內容包括：個人基本資料、幼年時期生命經驗、幫派生涯歷程及脫離幫派後之生活型態。 研究結果發現，受訪者幼年成長背景有其共通性，家庭結構均不完整、社經地位偏低、教養方式屬於放任式管教、學業成績不佳、鄰里關係較為複雜；成年後有幾項具關鍵性之影響因素致受訪者脫離幫派，即個人堅定意識的決定、結構性日常活動的改變及非正式社會控制的介入等，各因素之間交互影響。透過本研究之分析發現結論，以幫派脫離之形成過程進行幫派脫離之初探，期能在實務上提供助益。

Gang has always been a threat to public order. Although the police has made some effort to wipe out the gang, threats still exist and hard to exterminate. Current policy is incapable of solving the gang problem, due to a lack of understanding of the gang problem. Think about it in another way, if we want to do a research on how to break down the gang, we must learn from the ex-gang member to find out the best solution for different authorities to collaborate with each other. The present study refers to the literature from Taiwan and some other foreign literatures, using the life course, differential association and rational choice theory’s point of view to find out the key factor that persuade the member to leave the gang. This research is based on interviewing three ex-gang members with semi-structured questionnaire, which includes personal detail, childhood experience, gang experience and the lifestyle after leaving the gang. The main outcome of the study is that all three ex-gang member had similar growing background and family structure, with low social status and complicated neighbourhood relationship. The main factor which affected them to leave the gang is the strong self-awareness. Other factors like the changed of daily routine activities and the interference of informal social-control are also effective in helping the member to leave the gang.
