Military combat, posttraumatic stress disorder, and criminal behavior in Vietnam veterans.

Although data are inconclusive, popular perception has linked military combat, posttraumatic stress disorder (PTSD), and criminal behavior. This paper discusses the multifactorial elements of this association that include both conscious and unconscious parameters of psychologic functioning. Testimony on combat-related PTSD has been presented in the courtroom to support veterans' claims of not guilty by reason of insanity (NGRI) and diminished capacity and for consideration during judicial sentencing. Because there is a known connection between the degree of combat involvement and PTSD, verification through collateral sources of the veteran's report of combat experiences is an important component of forensic assessment. The DSM-III-defined diagnosis of PTSD and the presence of a dissociative state have particular relevance in NGRI determinations. In other aspects of the judicial process demonstration of the absolute presence or absence of PTSD is often irrelevant and should be replaced by efforts to establish plausible links between provable combat experiences and the circumstances of the crime.

Vietnam veterans in the general hospital.

Posttraumatic stress disorder is now well known to occur among Vietnam combat veterans. The interest in this diagnosis may have caused an unintentional neglect of veterans with problems that do not meet the strict criteria of DSM-III for this disorder. The authors studied 300 Vietnam veterans admitted to a general hospital to determine their level of symptomatology and to gather data on this previously unstudied group. More than 75 percent of the sample were medical-surgical patients; about 50 percent had high levels of depression and symptoms of posttraumatic stress disorder, or both. Combat veterans were considerably more symptomatic; more than 50 percent of the patients with the highest levels of combat activity were on nonpsychiatric wards. The authors suggest the need to identify Vietnam veterans on medical and surgical wards. Reluctance to talk about war experiences makes Vietnam veterans a group likely to be overlooked.
