Lifetime and current prevalence of specific psychiatric disorders among Vietnam veterans and controls.

To determine if Vietnam theater veterans were more likely than controls to have a specific psychiatric disorder other than posttraumatic stress disorder, the rates of specific psychiatric disorders were estimated using the Diagnostic Interview Schedule for national samples of veterans who served in Vietnam, other veterans of the Vietnam era, and matched civilian controls. Overall, there were few differences in rates of disorder between theater and other veterans; there were somewhat more differences between theater veterans and civilians. There were striking differences, however, in rates for most disorders, both lifetime and current, between male theater veterans with high levels of exposure to war zone stress and other male veterans or civilians. Female veterans exposed to high levels of war zone stress also had higher rates than other female respondents for several disorders.
