Following World War I, researchers began to study psychological and behavior problems resulting from war experiences. Today these problems are defined as Posttraumatic Stress Disorders (PTSD). The PTSD problems of Vietnam veterans have been widely reported but less is known about World War II and Korean veterans. A study was undertaken to examine PTSD problems of former prisoners of war from World War II and Korea. Five variables are measured: (1) length of time as a prisoner of war (POW); (2) where prisoners were captured, since prisoners of Japan endured longer captivity, worse conditions, and more severe treatment than European POWs; (3) age; (4) rank; and (5) branch of service. A sample of POWs (N=172) from an ex-POW organization completed a questionnaire designed to assess current occurrence of PTSD. Four percent reported never being troubled by PTSD symptoms and 25 percent reported always being bothered by these symptoms. Most of the remaining 71 percent had intermittent problems with PTSD. A noteworthy percentage had stable marriages with 88 percent married and a mean duration of current marriages of 35 years. However, these marriages may not denote emotional intimacy. Only age and rank at time of capture were significantly related to PTSD with lower ranking and younger veterans demonstrating greater current problems. The relationship between type of trauma and PTSD should be examined. References and the POW questionnaire are appended. (ABL)
