Psychological Assessment (Mar 1995) published the results of a study of World War Il aviators who were captured by German forces after they were shot down. Having located a total of 239 WWII aviator POW survivors, the researchers asked each veteran to participate in the study; 33 responded to the letter of invitation. Each of the 33 POW survivors was administered the Minnesota Multiphasic Personality Inventory, one component of which measures level of post-traumatic stress disorder or (PTSD). [Note: the higher the score, the higher the level of PTSD.] The aviators produced a mean PTSD score of 9.00 and a standard deviation of 9.32.
