Forensic social professionals work with mandated clients who pose a risk to others. They work in a wide range of occupational fields, such as probation services, juvenile detention centres, prisons and forensic care facilities. This work requires a specific set of skills, effective methods and targeted training. Our research group contributes to the professionalism and continuity of this field.

Lines of research within the research group

Supervising and reintegrating mandated clients often involves a number of different institutions, departments and employees. For successful reintegration, it is important that clients experience a consistent approach during the supervision and care provided by different professionals. The line of research Continuity examines what forensic social professionals need in order to achieve this consistency or ‘continuity’.

Among other things, we study:

  • the needs of clients and professionals when it comes to ongoing care and support;
  • collaboration between workers from different organisations and different specialities;
  • existing initiatives to promote continuity.


  • Mea culpa The complexity of financial problems among probation clients

What makes the daily activities of forensic social professionals effective? How do they successfully assist clients in reducing delinquent or antisocial behaviour, and how do they support such clients to reintegrate into society? What skills, attitude and knowledge are required?

This line of research focuses on the professional quality of this occupational group. Among other things, we look at how professionals make effective use of scientific knowledge, establish connections with the experiential knowledge of other professionals and with the clients preferences and experiences. Our research also takes the role of personal beliefs into consideration.
