Deradicalisation and Counter Violent Extremism

Two guides – an introduction to deradicalisation programmes, and an overview of what good CVE practice should look like – are being published today by CREST.

With colleagues James Lewis and Kim Knott, Sarah Marsden has reviewed the literature on CVE programmes, to give examples of what good CVE practice should look like. Dr Marsden has also created an introductory guide to deradicalisation programmes, setting out the types of interventions in operation, the methods they use, and how to evaluate their effects.

CVE II: A guide to good practice

Countering Violent Extremism: A guide to good practiceThis second guide on Countering Violent Extremism (CVE) provides an overview of what good practice in CVE should look like, giving examples that help explain the need for an evidence-based theory of change, as well as the targeting, delivery and evaluation of CVE programmes.

CVE has yet to develop a strong evidence base, making it difficult to determine which interventions are effective. In addition, because the factors which drive violent extremism are complex and wide-ranging, the boundaries of CVE are often unclear.

Nevertheless, over a decade of CVE programmes has produced valuable learning. The case studies in this guide include a range of models and reflect different aspects of good practice, relating to programme design, delivery, and assessment.

Ongoing research and evaluation is a priority, as there remains much to learn about the impact of initiatives designed to counter violent extremism.

Written by CREST Researchers Dr Sarah Marsden and Professor Kim Knott and CREST Associate James Lewis, this guide details where CVE programmes are targeted, the range of methods used, who delivers the different intervention programmes, and an overview of the impact of CVE practice, based on current evidence.

This guide was produced as part of our Evaluating Countering Violent Extremism project. More information about this project is available on our website at:

Deradicalisation Programmes: Introductory guide

Deradicalisation Programmes: Introductory guideDeradicalisation programmes seek to address the ideological, social, and personal issues that lead someone to become involved in violent extremism.

Their aim is to support the move away from terrorism in order to protect the public, reduce the risk of reengaging in violent extremism, and enable the individual to pursue a more positive future.

They are targeted at those convicted of terrorism or people assessed to be meaningfully involved in violent extremism. These interventions are distinct from other areas of countering violent extremism focused on earlier stages of the radicalisation process.

Deradicalisation programmes are often described as tertiary interventions which seek to prevent ongoing involvement in militancy. This is in contrast to primary interventions which aim to prevent radicalisation by increasing awareness about violent extremism and addressing ‘root causes’, or secondary interventions focused on those considered at risk of engaging in violent extremism.

This guide, by Dr Sarah Marsden, is an introduction to deradicalisation programmes, setting out the types of interventions in operation, the methods they use, and how to evaluate their effects.
