Survivors of imprisonment in the Pacific theater during World War II.

Data were obtained from 41 survivors of imprisonment by the Japanese during World War II. Interview data suggested that these individuals, despite the 40 years that had passed since their prisoner of war experiences, showed manifestations of posttraumatic stress disorder, notably a sleep disturbance marked by recurrent nightmares. MMPI data suggested significant pathology, characterized as an anxiety state, in this group. Half of the subjects met the full set of DSM-III criteria for posttraumatic stress disorder.
