In Veterans of the United States Armed Forces, military sexual trauma (MST) is a pervasive type of trauma associated with a host of physical and psychological sequelae. A growing literature suggests a relationship between history of MST and chronic pain. This study sought to clarify the relationship between MST and chronic pain among male and female Veterans and explore whether individual factors moderate this relationship. Design A baseline survey of 328 Veterans seeking care for chronic pain via behavioral pain treatments was conducted. Results MST was reported by 31.4% of the sample and uniquely predicted pain interference. A significant interaction was found between MST and age, such that younger Veterans with a history of MST reported greater pain interference than younger Veterans with no MST. Conclusion Findings provide further evidence that the experience of MST may intensify the overall burden of chronic pain and suggest that younger Veterans with MST seem to be most vulnerable to impaired pain rehabilitation. Unique study contributions include a robust sample of women and men with elevated rates of MST and examination of MST-age relationships concurrent with chronic pain.
