Retrospective Appraisals Mediate the Effects of Combat Experiences on PTS and Depression Symptoms in U.S. Army Medics.

A life-threatening traumatic experience can cause physical and psychological distress, but it can also be remembered with pride from having demonstrated one's courage and abilities under severe circumstances. Characteristics of the event, early response, as well as later personal reflection, together determine the individual's response to a traumatic event. We investigated how traumatic combat experiences and retrospective appraisals of those experiences affected reports of symptoms of posttraumatic stress and depression in 324 U.S. Army medics. Higher levels of combat experiences were associated with both appraisals of threat to life (r = .40) and appraisals of personal benefit of the deployment (r = .15). Threat appraisals were associated with increases (r = .33 and .29), whereas benefit appraisals were associated with decreases (r = -.28 and -.30, respectfully), in symptoms of posttraumatic stress and depression. These opposing mediation pathways led to weak or nonsignificant total effects, which concealed the effects of combat intensity on posttraumatic stress (R(2) = .28) and depression (R(2) = .24). Acknowledging the beneficial effects that a combat experience had on one's life was associated with less intense behavioral health symptoms and offset the detrimental effects of traumatic combat experiences.
