In this article, we discuss psychological approaches to the understanding of acts of violence and, specifically, psychodynamic approaches to both formulation and treatment. We suggest that the key theoretical paradigm of a psychodynamic approach involves the exploration and elaboration of the meaning of a violent act for the offender and describe the relevance of this approach for both legal assessments and clinical services in secure residential care. We argue that a psychodynamic approach can improve the quality of assessments of both psychopathology and risk and inform effective therapeutic interventions in hard-to-treat patients.
