Women Veterans are the largest veteran population yet have significant mental health disparities, greater than both civilian women and veteran men. This article used constructivist grounded theory methods to explore the experiences of women Veterans that led to mental health outpatient service use. Twelve women Veterans revealed meaningful stories on their experiences of trauma and their use of mental health services. A broader grounded theory process model emerged, linking the categories of Trauma, Transitions, Identity, and Structure. This research provides key insight into how women Veterans make health care–related choices and process traumatic events such as military sexual trauma.
