When Needed
Required when a claimant has experienced prolonged or repetitive trauma, such as abuse or modern slavery. The assessment quantifies the psychiatric injury and provides an expert opinion on causation within a claim for damages.
What Is a Complex PTSD Assessment?
A Complex PTSD assessment is a comprehensive clinical evaluation designed to identify symptoms arising from chronic interpersonal trauma. Unlike standard PTSD, this diagnosis—recognised in the ICD-11—encompasses broader disturbances in self-organisation, including emotional dysregulation and relational difficulties.
Within civil litigation, the assessment focuses on the nexus of causation between the index event and the claimant’s current clinical presentation. The expert must differentiate between pre-existing vulnerabilities and the psychological harm materially attributable to the index events described in the claim.
- Affective dysregulation — impaired ability to manage intense emotional states
- Negative self-concept — persistent feelings of worthlessness, shame, or guilt
- Interpersonal dysfunction — sustained difficulty in maintaining relationships or feeling close to others
- Re-experiencing — vivid intrusive memories, flashbacks, or nightmares regarding the trauma
- Avoidance behaviours — active attempts to evade internal or external reminders of the traumatic events
- Hypervigilance — a constant state of high alert or exaggerated startle response
Our experts ensure all reports are strictly CPR Part 35 compliant, providing the court with an objective analysis of the claimant’s condition. The evaluation addresses the prognosis and the likely duration of symptoms to assist in the calculation of damages.
Evidence is gathered through clinical interview, psychometric testing, and a detailed review of medical records. This rigorous approach ensures the expert opinion is defensible under cross-examination in a high-stakes legal environment.
