Chapter 7: Conducting Personal Injury Evaluations

The legal framework rests on tort law principles, which establish that defendants may be held liable when their breach of duty directly causes compensable harm to plaintiffs. The civil litigation process involves multiple stages where psychological experts become essential contributors, typically during discovery and trial phases, with their testimony governed by evidence rules requiring reliable methodology and sufficient empirical basis. A central ethical tension in personal injury work stems from the adversarial nature of litigation, demanding that evaluators maintain unwavering objectivity regardless of which party retained them, avoid dual relationships that compromise impartiality, ground opinions in comprehensive data from multiple sources, and actively resist partisan distortion of their findings. Establishing psychological harm requires assessing both functional impairment and causal attribution, with evaluators focusing primarily on how injury affects the plaintiff's capacity to work, relate to others, and engage in daily activities rather than simply documenting diagnostic labels, though posttraumatic stress disorder remains the most frequently claimed condition in these cases. The causality determination presents particular complexity because psychological difficulties are multifactorial, necessitating careful comparison of pre-injury and post-injury functioning while accounting for prior vulnerabilities and the legal doctrine of the eggshell plaintiff, which protects individuals with predisposing conditions from having their damages reduced. Conducting rigorous evaluations demands a multimethod approach integrating document review to establish baseline functioning, extended clinical interviews allowing direct behavioral observation, validated psychological instruments designed to assess current symptomatology and detect response bias, and collateral information from third parties to corroborate or challenge the plaintiff's account. Finally, experts must communicate findings through comprehensive written reports detailing all data sources and reasoning, and prepare to defend their opinions under cross-examination through depositions and courtroom testimony, always maintaining professional composure and prioritizing objective evidence over advocacy.
