Posttraumatic stress disorder, guilt, depression, and meaning in life among military veterans.

Veterans of various service eras (N = 174) completed an Internet survey about combat exposure, posttraumatic stress disorder (PTSD) symptoms, depression, guilt, and meaning in life. Results of a hierarchical regression indicated that younger age; higher levels of combat exposure, depression, and guilt; and lower meaning in life predicted greater PTSD severity. The interaction between meaning in life and depression also was significant, with a stronger inverse relation between meaning and PTSD at lower levels of depression.
