This chapter introduces the “Socialisation and Reasoned Action Strategic Communications” (SoRaSCo) model as a conceptual framework to understand better and improve P/CVE (Preventing/Countering Violent Extremism) online communication efforts. Building upon the theoretical foundations presented in the preceding chapters, it integrates socialisation theory, strategic communications approaches, and behaviour change models—specifically the Reasoned Action Model (RAM)—to offer a more cohesive lens to examine radicalisation and counter-narratives impact. The chapter argues that traditional radicalisation paradigms, often rooted in linear and psychology-centric thinking, fail to fully capture extremist pathways’ relational, social, and communicative dimensions. By contrast, SoRaSCo regards radicalisation as a dynamic social process shaped by the interplay of social agents, norms, and identity negotiations, all mediated by influential communicative platforms and narratives. The SoRaSCo model is then developed as a blueprint for more context-sensitive, audience-centred, and iterative P/CVE interventions. The approach highlights how strategic communications can counter extremist narratives more effectively through careful audience segmentation, ethically-informed data gathering, and continuous monitoring and evaluation. Ultimately, this chapter argues that integrating insights from socialisation, communication theory, and behaviour change frameworks is essential for designing and deploying counternarratives that resonate authentically and measurably reduce the appeal of extremist messages.
