I just stumbled across this interesting article; “Mental Health Care Provision in the U.K. Armed Forces”. What struck me was the massive difference between US and UK soldiers reporting of PTSD.
“The prevalence of PTSD among U.S. forces returning from Iraq has approached 20% of combat personnel. This is in contrast to U.K. forces, which have reported approximately 5% using the same screening tools. There are differences between the forces deployed, some of which may explain the differences in mental health outcomes: U.S. troops are younger, less experienced, deploy for longer tours, and are more likely to be reservists than U.K. forces, all of which are independent risk factors for the development of symptoms of PTSD. A further explanation is that the higher levels of reporting may reflect societal and cultural factors not necessarily associated with deployment.”
