Forensic Case Formulation

Formulation is the process or product of gathering and integrating diverse information to develop a concise account of the nature and etiology of the problems affecting a person's mental health to guide idiographic treatment design and other decision-making. Formulation is a core competency in mental health practice, including forensic mental health; however, there is no agreement concerning the details of how it should be done or how to evaluate it, either generally or more specifically with respect to forensic mental health. The purpose of this paper is to raise specific issues in the practice and evaluation of forensic case formulation, and so enhance the profile of this important area of work. In this paper, we (1) define case formulation and describe its key features, (2) specify criteria for evaluating case formulation, and (3) address challenges in forensic practice, with suggestions for advancing practice through research. We conclude with a proposed research agenda that we hope will encourage and promote activity in this important area.
