Various theoretical approaches assume that identity diffusion is an influencing factor of extremism. However, there are hardly any empirical tests on this relationship. Based on a nationwide survey of 8,317 young people in Switzerland, the study analyses whether identity diffusion is associated with right-wing extremist, left-wing extremist, and Islamist extremist attitudes. In addition, the study tests whether identity diffusion mediates the influence of family and school-related variables on extremist attitudes. The results show that identity diffusion primarily increases approval of left-wing extremist and Islamist extremist attitudes. Furthermore, identity diffusion mediates to a small extent the influence of parenting on extremist attitudes.

In criminological research the relationship between religion and delinquency has received great attention. Religiosity has been shown to be a protective factor for violent behaviour, drug use and other types of crime. In contrast, the relationship between religion and extremism was rarely investigated and then almost exclusively in relation to Islamist extremism. This paper presents results of a youth survey on extremism in Switzerland. A total of 8317 young people in ten cantons were interviewed about right-wing, left-wing and Islamist extremism. The study allows in a unique way to analyse religion, religiosity and religious attitudes in relation to three forms of extremist attitudes. The results show that religion is an important influencing factor of extremism, but religious affiliation and religiosity are less important than specific religious attitudes such as religious tolerance and religious exclusivity.

This article aims to better understand the determinants which support the ideologies of the Radical Left among young people in Switzerland. The analyses presented in the article are based on a survey on the theme of political radicalism which has been carried out in secondary schools on level II. The findings showed that economic and political deprivation, as well as a high degree of anti-authoritarianism, increase the probability of adhering to the different ideologies of the Radical Left. They also suggest that several aspects of the school context have an impact on the ideological positioning of young people.

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.
