Chronic pain experience after deployment can be reduced if the war veterans are more optimistic before deployment. In the study, it was found that higher levels of optimism before deployment were linked with a lower likelihood of reporting new pain after deployment.
Many veterans experience chronic pain after deployment. This study of almost 21,000 U.S. Army soldiers who deployed to Afghanistan or Iraq examined the association between feelings of optimism (such as expecting the best and believing good things will happen) before deployment and new reports of pain after deployment, including new back pain, joint pain, and frequent headaches.
Higher levels of optimism before deployment were linked with a lower likelihood of reporting new pain after deployment, even after accounting for demographic, military and combat factors.
