According to new research conducted at Walter Reed Army Institute of Research in Silver Spring, Maryland, the proportion of soldiers using mental health services nearly doubled between 2003 and 2011. Furthermore, researchers found a small but significant decrease in the perceived stigma associated with seeking mental health services. In 2003, only about 8 percent of soldiers sought mental health services. In 2011, about 15 percent of soldiers did so. Even with the increase in the number of soldiers seeking mental health help, researcher Phillip Quartana stated that two-thirds of soldiers with post-traumatic stress (PTSD) or major depression symptoms did not seek treatment between 2002 and 2011. More than 25 percent of active infantry soldiers from the conflicts in Afghanistan and Iraq, dating back to the beginning of the conflicts in 2001, met self-reported criteria for these diagnoses. While the number of soldiers seeking help has increased and the stigma associated with seeking mental health services has decreased, these results demonstrate that more progress is needed to increase soldiers’ use of mental health care services. Researchers used data from active-duty personnel who completed Health-Related Behavior Surveys between 2002 and 2011. This study is the first to empirically examine trends concerning utilization of services and stigma across multiple wars. The study was published online in the American Journal of Public Health .
