Abstract

Objectives:

To examine whether the association between posttraumatic stress disorder (PTSD) and injury perceptions (ie, consequences, emotional representations, and coherence) differs for Veterans with mild traumatic brain injury (mTBI) compared with Veterans with non-TBI (ie, orthopedic).

Participants:

Eighty Veterans injured during post-9/11 deployments.

Design:

Observational, 2×2 factorial design.

Main Measures:

Injury histories ascertained using the Ohio State University TBI-Identification Method and Deployment Injury Questionnaire; Injury Perception Questionnaire-Revised (injury perceptions); Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (PTSD diagnosis); and PTSD Symptom Checklist-Civilian Version (PTSD symptoms).

Results:

The association between PTSD diagnosis and injury perceptions did not differ between Veterans with mTBI and those with non-TBIs, adjusting for age, subjective pain, and depressive symptoms. PTSD symptom severity was significantly associated with injury consequences (P < .0001) and emotional representations (P < .0001), irrespective of injury type (mTBI vs non-TBI). Only injury coherence was associated with a significant interaction between PTSD symptom severity and mTBI (P = .04).

Conclusion:

PTSD symptom severity influences perceptions about mTBI and non-TBIs sustained during deployment. Altering injury perceptions may be an important treatment target for Veterans with co-occurring PTSD and deployment-related injuries.
