The authors performed structured psychiatric examinations of 188 former
prisoners of war (POWs). Sixty-seven percent had had posttraumatic stress
disorder. Of those affected, 29% had fully recovered, 39% still reported
mild symptoms, 24% had improved but had moderate residual symptoms, and 8%
had had no recovery or had deteriorated. Presence of posttraumatic stress
disorder was not significantly correlated with other mental disorders.
Delayed onset was not seen. The findings confirm the DSM-III concept of and
criteria for posttraumatic stress disorder.
