The U.S. military has long been regarded as an institution that attracts individuals with a strong sense of duty, resilience, and physical and mental fitness. However, recent research has revealed a more complex picture, particularly regarding the mental health status of soldiers prior to enlistment. Studies have shown that a significant proportion of soldiers enter the military with pre-existing mental health conditions, such as depression, anxiety, substance abuse, and intermittent explosive disorder. This finding raises critical questions about the effectiveness of pre-enlistment screening processes and the need for enhanced mental health support within the military.
Research conducted by the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) has demonstrated that nearly one in five soldiers had a common mental illness before enlisting, despite the military’s screening procedures. These conditions were not only prevalent but, in some cases, more so in the military population than in the civilian population. For example, intermittent explosive disorder—a disorder characterized by uncontrolled outbursts of anger—was found at nearly six times the civilian rate among pre-enlistment soldiers. These findings underscore the importance of understanding and addressing mental health issues before and during military service.
Pre-Enlistment Mental Health Conditions
The Army STARRS studies, which included confidential surveys and interviews with over 5,400 soldiers, revealed that a wide range of mental health conditions were present prior to enlistment. These conditions included depression, anxiety disorders, attention deficit hyperactivity disorder (ADHD), panic disorder, bipolar disorder, substance abuse, and intermittent explosive disorder. The prevalence of these conditions was often comparable to that seen in the civilian population. However, certain disorders, such as intermittent explosive disorder, were significantly more common among military recruits than among civilians.
Intermittent explosive disorder, in particular, was the most frequently observed condition among pre-enlistment soldiers. This disorder is characterized by sudden, impulsive episodes of aggression that are disproportionate to the situation. The high prevalence of this condition in the military population suggests that individuals with a predisposition for aggression or emotional dysregulation may be more likely to enlist in the military. As one of the study's lead researchers, Ronald Kessler, noted, those who join the military tend to have "a lot more acting-out kind of mental disorders," including higher rates of aggression and conflict.
Other findings also highlighted the presence of pre-enlistment suicidal ideation and suicide attempts. More than 8% of soldiers had considered suicide, and 1.1% had made a suicide attempt before joining the military. These rates, while lower than in the general population, are still significant, especially considering that the military typically excludes individuals with a history of suicide attempts. The fact that these individuals were still able to enlist suggests that the current screening process may not be sufficient to identify and address mental health risks.
Challenges in Pre-Enlistment Screening
The military's pre-enlistment screening process is designed to identify individuals with mental health conditions that could impair their ability to serve. However, the studies suggest that this process may not be effective in preventing individuals with pre-existing mental health issues from enlisting. One of the main reasons for this is the reliance on self-disclosure. Applicants are asked to report any history of mental health conditions, but many are reluctant to do so because of the potential consequences. As Dr. Elspeth Ritchie, a former chief psychiatrist in the Army, explained, individuals who want to join the military are often aware that disclosing a history of mental illness, especially a suicide attempt, could prevent them from being accepted.
This self-reporting approach has limitations, particularly because individuals may not accurately perceive or disclose their mental health status. In some cases, they may not recognize that their behavior or emotions indicate a mental health issue. In other cases, they may downplay or hide their symptoms in order to pass the screening process. This can lead to the enlistment of individuals who are at higher risk for mental health complications later in their service.
Another challenge is the potential impact of recruitment pressures. During periods of high demand for recruits, such as during the wars in Iraq and Afghanistan, some recruiters may have discouraged applicants from disclosing mental health issues. This could have contributed to the enlistment of individuals with pre-existing mental health conditions, which in turn may have contributed to the rising rates of mental health issues and suicides among soldiers.
Post-Enlistment Mental Health Trends
Once enlisted, the prevalence of mental health disorders among soldiers increased significantly. The studies showed that the rates of depression, anxiety, panic disorder, and post-traumatic stress disorder (PTSD) were much higher among soldiers than in the civilian population. For example, nearly 5% of soldiers developed depression, nearly 6% developed anxiety disorder, and nearly 9% developed PTSD during their service. These increases suggest that the military environment, including exposure to combat and other stressors, may exacerbate existing mental health conditions or contribute to the development of new ones.
The rise in mental health disorders was also reflected in suicide rates. The studies found that soldiers who had been deployed to Afghanistan or Iraq had higher rates of suicide compared to those who had not been deployed. However, even soldiers who had not been deployed also experienced a steady increase in suicide rates during the study period. This finding suggests that factors beyond deployment, such as the overall stress of military service, may contribute to mental health decline.
Implications for Mental Health Support and Policy
The findings from these studies have important implications for mental health policy within the military. One key takeaway is the need for improved pre-enlistment screening. While the current process relies on self-disclosure, it may not be sufficient to identify individuals with mental health conditions that could affect their service. Alternative approaches, such as more comprehensive mental health assessments or the use of standardized screening tools, may be necessary to better identify at-risk individuals.
However, simply screening out individuals with mental health conditions may not be the best solution. As Dr. Matthew Nock, a psychologist involved in the study, noted, the goal should not be to exclude individuals with mental health issues but to provide them with the necessary support and treatment. This could involve implementing early intervention programs that focus on building resilience, providing mental health education, and offering access to counseling and therapy.
Another important consideration is the need for ongoing mental health support during and after military service. The studies found that the rates of mental health disorders increased significantly after enlistment, indicating that the military environment may contribute to the worsening of pre-existing conditions or the development of new ones. To address this, the military should consider expanding access to mental health services, including counseling, therapy, and peer support programs.
In addition, the findings highlight the importance of addressing the mental health needs of young recruits. The study on enlistment at a young age suggests that individuals who enlist at a younger age may be more vulnerable to the stressors of military service. This is particularly concerning given the evidence that childhood adversity can have long-term effects on mental health and brain development. Experts have called for the minimum enlistment age to be raised to 18 in order to better protect young recruits from the potential harms of military service.
Conclusion
The research on pre-enlistment mental health among U.S. soldiers reveals a complex picture of mental health challenges that exist before, during, and after military service. A significant proportion of soldiers enter the military with pre-existing mental health conditions, which may be exacerbated by the stressors of military life. These findings highlight the need for improved screening processes and enhanced mental health support within the military. While the current system relies on self-disclosure, it may not be sufficient to identify at-risk individuals. Instead, the focus should be on early identification, intervention, and support to help soldiers manage their mental health and reduce the risk of negative outcomes such as suicide.
The studies also underscore the importance of addressing the mental health needs of young recruits, who may be particularly vulnerable to the stressors of military service. Experts have called for policy changes, including raising the minimum enlistment age and implementing more comprehensive mental health programs. These efforts are essential to ensuring the well-being of military personnel and addressing the growing concerns about mental health within the armed forces.
