The cohort of all Australian former army conscripts of the Vietnam era was followed from 1965-1982 to determine mortality rates & causes of death. 91 suicide victims were compared to a random sample of survivors. One finding was that suicides were more likely to have had a history of psychiatric diagnosis & treatment during service. However, service in Vietnam was not associated with suicide. The difference in death rates between high scorers & low scorers on a 4-item model was 46-fold.
