Scholars rarely compare youth gangs members and extremists. Yet, studies of gangs can yield relevant information on extremist groups, and vice versa. This article compares youth gang members with left-wing, right-wing and Islamist extremists. The aims of this article are to determine the prevalence of gang members and extremists among young people in Switzerland, to determine the overlap, if any, between gang members and extremists, and to analyse the differences and similarities of individual characteristics among the gang members and extremists, their delinquency and victimization. Comparisons of such groups may provide important insights into the individual members of these groups. The similarities between gang members and extremists could give us information for the prevention programmes. The study was based on a self-report survey completed by 8317 students of non-compulsory school age (about 17 years old) and living in Switzerland. The results show greater numbers of young people affiliated with gangs (6.6 percent) and left-wing extremism (6.2 percent), and more similarities between the members of gangs and left-wing extremists, compared with the other forms of extremism.

学者们很少将青年团伙成员和极端分子进行比较。然而，对帮派的研究可以产生关于极端组织的相关信息，反之亦然。本文将青年帮派成员与左翼、右翼和伊斯兰极端分子进行了比较。本文的目的是确定瑞士年轻人中帮派成员和极端分子的流行程度，确定帮派成员和极端分子之间的重叠（如果有的话），并分析帮派成员和极端分子之间个体特征的异同。极端分子，他们的犯罪和受害。对这些群体的比较可能会提供对这些群体的个别成员的重要见解。帮派成员和极端分子之间的相似之处可以为我们提供预防计划的信息。该研究基于由居住在瑞士的 8317 名非义务教育年龄（约 17 岁）学生完成的自我报告调查。结果显示，与其他形式的极端主义相比，与帮派 (6.6%) 和左翼极端主义 (6.2%) 有关联的年轻人数量更多，帮派成员与左翼极端主义分子之间的相似性也更多。
