Are psychologically vulnerable youth more susceptible to extremism than their peers? Today's radicalized Westerners are young and their extreme opinions develop during adolescence, a period in which challenges to worldview and self-perception can be potent motivators for extremist engagement, as shown in work on significance quests (Kruglanski et al., Political Psychology, 2014, 35, 69-93) and general strain (Agnew, Theoretical Criminology, 2010, 14, 131-153). To better understand the developmental paths to extremism, more knowledge is needed about the interplay among vulnerability factors. Thus, this study investigates whether psychological vulnerabilities among Norwegian youth increases susceptibility to extremism. It specifically explores psychological vulnerabilities in relation to mental illness, traumatic experiences, early socialization, perceived discrimination, social capital, and delinquency. The study's data come from Young in Oslo 2015, a population-based, cross-sectional survey of over 24,000 adolescents conducted in upper secondaryschoolsinthe Norwegian capital(n = 10.932).Overall,Osloyouthare representativeofNorwegian youth, demographically, psychosocially, and with regard to extremism. This study measured four expressions of extremism and conducted structural equation modeling (SEM). Results indicate that factors indicative of psychological vulnerabilities are relevant in explaining susceptibility to extremism among Norwegian youth, especially when viewed in relation to specific demographic variables. Quests for significance and opposition to collective strains appear to be relevant to the relationship between extremism and psychological vulnerabilities. More broadly, this study suggests that extremism develops as a result of complex interactions among numerous factors, that the ordering of these factors varies, and that there is no one trajectory to extremism.
Public Significance StatementIt is commonly assumed that no relationship exists between mental health challenges and extremism. This study challenges this view, suggesting that psychological vulnerabilities are relevant to explaining youth susceptibility to extremism. It also advances the idea that there are numerous developmental paths to extremism, all resulting from the complex, temporal interplay among factors. These findings improve the general knowledge about extremism and have implications for the development of sustainable and effective preventive measures.
