Examining Ethnoracial Differences in Retention in Evidence-Based Treatments for Posttraumatic Stress Disorder Secondary to Military Sexual Trauma.

Improving and expanding mental health treatment for Veterans who have experienced military sexual trauma (MST) is currently a top priority in Veterans Healthcare Administration. Many of these Veterans develop posttraumatic stress disorder (PTSD), and there is increasing recognition that diversity is a core treatment consideration for Veterans who have experienced trauma. As such, more information is needed concerning the relationship between trauma-focused treatment attrition and ethnoracial identity in Veterans who have experienced MST. This article presents two studies exploring dropout from a Midwestern Department of Veterans Affairs (VA) PTSD clinic in samples of Veterans who experienced MST. These studies aim to reduce this knowledge gap by contrasting Black and White Veterans' retention in trauma-focused care. In Study 1 (n = 141), we examined ethnoracial differences in dropout in a cohort of treatment-seeking Veterans who experienced MST and engaged in cognitive processing therapy (CPT) in a VA specialty PTSD clinic. In Study 2 (n = 109), we explored the same questions related to treatment attrition in a separate cohort of treatment-seeking Veterans who experienced MST and engaged in prolonged exposure (PE) in a VA specialty PTSD clinic. Results from both studies did not indicate ethnoracial differences in attrition rate (for both total sessions and an 8-week minimally adequate care [MAC] window) across evidence-based PTSD treatment. However, it remains important to consider the impact of racial and cultural factors on retention. Future research should aim to recruit a larger racially and ethnically diverse sample to explore possible varying retention outcomes of CPT and PE for MST-related PTSD.
