Radicalisation processes impacting on disaffected and indoctrinated persons and the later involvement of some of them in acts of terrorism are of growing concern for European citizens, their governments and the wider international community. Addressing this threat requires effective prevention policies which some EU member states have been proactive in developing. Effective policies need reliable diagnostic tools designed to identify individuals and groups who might pose a threat.

The publication provides a review of existing approaches and tools to identifying, monitoring and assessing radicalisation in Europe and beyond. It further offers a conceptual framework of radicalisation risk and vulnerability indicators and their interpretation as a basis for developing early-warning mechanisms for frontline practitioners in countries which are yet to develop specific prevention and counter-radicalisation policies. The target group of the guide are policymakers at national and EU levels, as well as practitioners directly involved in the prevention of radicalisation in Central and Eastern Europe and beyond.
