Background: Military sexual trauma (MST) is reported by up to 74% of women veterans in the United States and is a driver of poor behavioural and physical health. Self-compassion is a transdiagnostic, protective factor linked with improved posttraumatic stress disorder (PTSD), depression, and health behaviours. Thus, Mindful Self-Compassion training (MSC) may help ameliorate MST-related impacts. However, MSC can also temporarily increase distress (i.e. backdraft).
