Forensic therapies are sometimes subject to great fluctuations in terms of their continuity of implementation, their quality, as well as their school of thought. Additionally, they are not adequately measured or evaluated. In many cases, their documentation is insufficiently structured and often incomplete. In this context, the change processes of the client are not well documented and important long-term goals are sometimes lost in the process (Melton et al., 2007). However, well-founded findings are available as to which procedures have proven themselves both empirically and in practice in forensic risk assessments. This article offers an overview of the current forensic assessment process with a particular focus on the Forensic Operationalized Therapy/Risk Evaluation System (FOTRES).
