Although professional practice in forensic psychiatric settings is, in our opinion, extremely complex and requires the input of different disciplines, conceptual or theoretical models guiding such practice remain rare or poorly adapted. In this article, we propose an interdisciplinary model of practice to fill this gap. The objectives of this article are: to provide an overview of the literature review conducted; to report, as faithfully as possible, on our general method of consulting with employees practicing in a forensic psychiatric institution; and, finally, to propose an interdisciplinary practice model resulting from this general consultation within the organization.
