Abstract
Psychologists who work as therapists or administrators, or who engage in forensic practice in criminal justice settings, find it daunting to transition into practice in civil cases involving personal injury, namely psychological injury from the psychological perspective. In civil cases, psychological injury arises from allegedly deliberate or negligent acts of the defendant(s) that the plaintiff contends caused psychological conditions to appear. These alleged acts are disputed in courts and other tribunals. Conditions considered in psychological injury cases include posttraumatic stress disorder, depression, chronic pain conditions, and sequelae of traumatic brain injury. This article outlines a detailed case sequence from referral through the end of expert testimony to guide the practitioner to work effectively in this field of practice. It addresses the rules and regulations that govern admissibility of expert evidence in court. The article provides ethical and professional guidance throughout, including best practices in assessment and testing, and emphasizes evidence-based forensic practice.
