A psychological injury is the psychological or psychiatric consequence of a traumatic event or physical injury. Such an injury might result from events such as abusive behavior, whistleblower retaliation, bullying, kidnapping, rape, motor vehicular collision or other negligent action. It may cause impairments, disorders, and disabilities perhaps as an exacerbation of a pre-existing condition (e.g., Drogin, Dattilio, Sadoff, & Gutheil, 2011; Duckworth, Iezzi, & O'Donohue, 2008; Kane & Dvoskin, 2011; Koch, Douglas, Nicholls, & O'Neil, 2006; Schultz & Gatchel, 2009; Young, 2010, 2011; Young, Kane, & Nicholson, 2006, 2007). Psychological injury is considered a mental harm, suffering, damage, impairment, or dysfunction caused to a person as a direct result of some action or failure to act by some individual. The psychological injury must reach a degree of disturbance of the pre-existing psychological/ psychiatric state such that it interferes in some significant way with the individual's ability to function. If so, an individual may be able to sue for compensation/ damages. Typically, a psychological injury may involve posttraumatic stress disorder (PTSD), traumatic brain injury (TBI), a concussion, chronic pain, or a disorder that involves mood or emotions (such as depression, anxiety, fear, or phobia, and adjustment disorder). These disorders may manifest separately or in combination (co-morbidity). If the symptoms and effects persist, the injured person may become a complainant or plaintiff who initiates legal action aimed at obtaining compensation against whoever is considered responsible for the injury. Diagnosis and treatment Psychologists and psychiatrists are those professionals typically qualified by their regulating or licensing bodies or boards to diagnose and treat psychological injuries. Psychologists are trained in the study of behavior and its assessment, diagnosis, and treatment. Many psychological tests are limited in their use to psychologists, as psychiatrists are unlikely receive substantial training in test administration and interpretation. However, being medical professionals, psychiatrists have skills and a knowledge base not typically available to psychologists. The Diagnostic and Statistical Manual of Mental Disorders—now in its fourth edition (DSM-IV-TR, American Psychiatric Association, 2000)—will soon be updated by a fifth edition slated for publication in 2013 (see Young and First, 2010, for a critique). This Manual is prepared under the aegis of the American Psychiatric Association, but psychologists contribute to this process by participating in its working groups. Rehabilitation and other clinical psychologists—such as trauma psychologists—may be in professional contact with injured survivors at the onset injury, shortly thereafter, and throughout the course of
