Abstract: Female veterans are an underserved population among US military members, with unique challenges underlying high mental illness rates, substance use disorders, and suicidality. Military sexual trauma, difficulty in civilian transition, and other barriers exacerbate these issues, creating disproportionate mental health burdens compared to their male peers. Despite existing treatment programs, female veterans experience stigma and barriers to receiving care access in male-centered treatment models. This thesis explores the intersection of mental health, substance use disorders, and suicide risk in female veterans, gender-sensitive care gaps, and current Department of Veterans Affairs treatment interventions. It offers recommendations for increasing access and care quality for female veterans. The findings emphasize the importance of specialty-level treatments addressing female veterans' needs to enhance mental health outcomes and reduce suicide risk within this vulnerable population. Future focus should be on the development of gender-specific interventions to overcome gender-related barriers, assess the efficacy of novel treatment approaches, such as telehealth and trauma-informed care, and explore policy changes that can enhance access to mental health treatment for women veterans.
