Diagnostics and assessments regarding processes of individual disengaging from (violent) extremism are characterized by a large variety of methodological and theoretical foundations and influences. Nonetheless, a focus on either (individual) risks or resources is prevalent in most contemporary approaches. As a result, intervention planning is usually informed by an assessment of individual risk and resource factors identified through the structured analysis of the following categories: ‘biography’, ‘needs’ and ‘social integration’. Yet, even though practical experience seems to support the basis underpinning such an approach, the scarcity of supporting empirical evidence and the results of radicalization research point to a need for continued development. To this end, further empirical research on disengagement processes is necessary to fill in remaining evidence and knowledge gaps. Additionally, a comprehensive theoretical basis is needed to fully comprehend radicalization processes in their complexity, and to assess disengagement processes in a reasoned manner. Consequently, this article proposes a structure for the integration of ‘resonance’ as a third dimension alongside the current focus areas of ‘risk’ and ‘resource’. The article then goes on to map out the necessary steps for a more holistic intervention planning in line with this expansion of the diagnostic process.
