The outcomes included severity of post-traumatic stress disorder (PTSD) measured by Clinician Administered PTSD Scale-5, the level of post-traumatic stress symptoms measured by the PTSD Checklist, DSM-5, and the level of mental health symptoms measured by the Brief Symptom Inventory.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A greater number of lifetime (but not childhood) traumatic experiences were found among those with mTBI and PPCS compared to those with mTBI but\n                      <jats:italic>no<\/jats:italic>\n                      PPCS or no mTBI; however a greater number of childhood traumatic experiences were associated with poor mental health symptoms in areas of somatization and interpersonal sensitivity, but only among those with mTBI and PPCS.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The findings of this exploratory study show that the number of lifetime traumatic experiences may be related to persistent post-concussive symptoms; however, only the number of childhood trauma was associated with mental health symptoms among those with persistent symptoms. These findings support screening for childhood and lifetime traumatic experiences during evaluations at clinic intake to improve risk assessment, treatment planning, and recovery expectations and outcomes. While the results may highlight the need for early identification of at-risk individuals for persistent symptoms to enhance readiness and return-to-duty rates, further studies are needed to elucidate the mechanisms of these associations.<\/jats:p>\n
