Project description

Working with PVLs requires expertise on different levels. Generally, a three-stage process is involved among individuals and organizations: from the 'aha'-phase (identification of a PVL) and the 'hmm'-phase (what to do now that we identified a PVL?) to the 'okay'-phase (based on early detection of a PVL, expertise can be applied and developed).

In the 'aha'-phase we focus on awareness of the existence of the target group within the mental healthcare caseload. Together we explore the social context of intended extreme violence. We also consider the backgrounds of PVLs as a subject within various professional practices. In the 'hmm'-phase we bring in current affairs, scientific research, and actual experience, and we concentrate on refining the significance of this subject for the field involved.

We also address different kinds of PVLs, processes of radicalization, as well as research on the breeding grounds for processes of radicalization and early detection. In the third phase ('okay') we explore collaboration with professionals within and outside one's immediate practice or institution. This phase also highlights the theme of 'sharing information', based on the book 'The patient's secret' (Trifier-ISI, 2015).

Themes addressed are:

  • demarcation of the PVL group
  • breeding ground of radicalization
  • Processes of radicalization
  • forms of intended extreme violence
  • jihad and exit travellers
  • radicalization and disorders
  • diverse evidence- and practice-based approaches
  • model: pathway of intended extreme violence
  • sharing of information

Group/team composition:

  • Group size is 12-15 participants
  • Participants from disciplines linked to providing care to clients can sign up for these courses, as well as members of multidisciplinary teams involved in interpreting processes associated with clients' behaviour.


  • After completing the workshop, participants have skills and knowledge that allows them to:
  • Support colleagues who deal with detection of PVLs in their caseload
  • Recognize PVLs and possible links to mental healthcare
  • Identify signs of radicalization
  • Refer effectively to specialist care
  • Establish an internal network to structure the sharing of expertise with their own organization
