This is first and foremost a clinicians’ guide: it has been written with the aim of supporting people to develop, maintain and repair relationships within their work as forensic practitioners.Research repeatedly finds that client perception of the therapeutic relationship is a significant factor in treatment success; however, data suggests that forensic psychologists have a poor history of trust and engagement with people in prisons. Tackling this issue head‑on, this book explores key factors in working relationships across a broad range of forensic client groups, settings and tasks and reflects on specific points of tension in forensic therapeutic relationships. Drawing on the expertise of a diverse range of authors, it unpicks the challenges in building such relationships and explores factors such as neurodiversity, extremism, professional boundaries and working effectively with women and children. It outlines how productive working relationships can be developed and maintained, and highlights the essential constituent parts of that process, using both a theoretical and experiential lens. Finally, this book identifies and discusses examples of good practice from both practitioner and, in places, service participant perspectives. Guiding practitioners to find respectful and connected solutions, while maintain‑ing safety and appropriate professional and personal boundaries.
