As children enter adolescence, their understanding of society and their place in it begins to expand, and they develop political views and ideas about whether and how they might participate in shaping society. This decision process may lead to disengagement and political apathy, democratic engagement, or indeed radicalized engagement that is marked by support for undemocratic, violent means. Across disciplines (psychology, political science, and criminology), different theoretical frameworks are used to explain what turns adolescents towards versus away from radicalization - e.g., the quest for significance model, the uncertainty-identity-model, a justice seeking and unfairness judgement model, a criminological model based on general strain theory, and a gender-identification based model. This talk presents data from an ongoing longitudinal study running from 2024 - 2026 (6 waves total) in five Austrian states (Vienna, Upper Austria, Carinthia, Burgenland, and Salzburg). 1616 students in the 8th grade of different school types (Mage = 13.97 years, SD = .88 years, 49 % female / 48 % male / 4 % other) participated in the first wave of data collection in spring of 2024, with data collections taking place in the autumn and spring of each year. Using one lesson in school to participate in the study, students filled in a survey containing various age-adjusted measures of predictors pertaining to the above-mentioned explanatory models. This talk presents preliminary analyses of the distribution and prevalence of these predictors in the sample and their relations to different political attitudes and behavioural outcomes, such as voting intentions, attitudes towards voting, engagement in collective action, and support of radicalized and violent political means.
