Concept of and approaches toward a developmental prevention of radicalization: Promising strategies to keep young people away from political, religious, and other forms of extremism

Abstract Radicalization and violent extremism in young people are growing problems in almost every society around the globe. This article starts by briefly summarizing the result of several comprehensive reviews on the prevention of radicalization and violent extremism. Based on a new social-developmental model of radicalization, it then introduces the concept of developmental prevention and presents a review of prevention principles, approaches, and programs derived from a developmental perspective within four different fields of proximal radicalization processes. These include (1) identity problems; (2) prejudice and negative intergroup attitudes; (3) extremist narratives, beliefs, and ideologies; and (4) antisocial development. Overall, several approaches and programs reveal promising effect sizes for a developmentally founded prevention of radicalization. However, more sound evaluations are needed to further promote this field.
