The association of deployment stressors and PTSD and depression symptoms in military mothers

Previously deployed mothers report higher levels of posttraumatic stress and depression symptoms than non-deployed mothers. However, the specific stressors encountered during deployment that account for elevated clinical symptoms are not well understood including the impact of Military Sexual Trauma (MST) in the context of other deployment-related stressors. This study examined whether MST during deployment, degree of combat exposure, and length of deployment will each be associated with posttraumatic stress and depression symptoms among previously deployed mothers. Participants included 113 mothers (86.6% White) who had previously been deployed to Iraq or Afghanistan during the post 9/11 conflicts. Logistic regressions revealed that mothers who experienced MST during deployment were five times more likely to report clinically significant posttraumatic stress symptoms and two times more likely to report clinically significant depression symptoms. When controlling for MST, degree of combat exposure and length of deployment were not significantly associated with posttraumatic stress or depression symptoms. The present study fills an important gap in the literature and implicates MST as an important correlate of post-deployment functioning for military mothers. Findings from this study can be used to inform both prevention and intervention efforts.
