Assisting the Courts in Understanding and Connecting with Experiences of Disconnection: Addressing Trauma-Related Dissociation as a Forensic Psychologist,Part I

Although trauma-related dissociation (TRD) is a common reaction to trauma often associated with significant impairment and prognoses that necessitate extended treatment, few assessors are knowledgeable about dissociation, its assessment, and methods for presenting information about it to courts in a way that is evidence-based yet understandable. This paper is the first part of a two-part series that aims to expand forensic assessors’ knowledge about TRD and enhance their ability to assess and present information about dissociation. This article provides overviews of research about dissociation and offers suggestions on how expert witnesses can assist counsel and courts in understanding dissociative reactions and their importance in personal injury cases. Specifically, we define dissociation; discuss the links between trauma, dissociation, and posttraumatic stress disorder; briefly review neurobiological findings related to dissociation; describe dissociative-related impairment and treatment; review challenges that can interfere with accepting and understanding dissociative symptoms; and suggest methods for helping counsel and courts accurately understand and consider TRD in assessing cases and deciding their outcomes.
