This is a retrospective, multi-site, cross-sectional study utilizing data collected from a total of 289 Operation Iraqi Freedom\/Operation Enduring Freedom Veterans who were classified into diagnostic groups using the symptom attribution and classification algorithm and the VA clinical reminder and comprehensive traumatic brain injury evaluation. The Neurobehavioral Symptom Inventory was used to assess mTBI symptom number and severity. The World Health Organization Disability Assessment Schedule 2.0 was used to assess functional impairment. Symptom profiles differed between diagnostic groups irrespective of symptom attribution method used. Veterans with both mTBI and BHCs and those with BHCs alone had consistently greater number of symptoms and more severe symptoms relative to no symptom and symptoms resolved groups. Symptom number and severity were significantly associated with functional impairment. Both symptom number and functional impairment were significantly associated with the number of mTBI exposures. Together, these results informed evidence-based theories on understanding why symptoms and functional impairment persist among some OEF\/OIF Veterans.<\/jats:p>","DOI":"10.1093\/milmed\/usy306","type":"journal-article","created":{"date-parts":[[2019,3,22]],"date-time":"2019-03-22T12:05:19Z","timestamp":1553256319000},"page":"138-147","source":"Crossref","is-referenced-by-count":4,"title":["Relationships and Evidence-Based Theoretical Perspectives on Persisting Symptoms and Functional Impairment Among Mild Traumatic Brain Injury and Behavioral Health Conditions"],"prefix":"10.1093","volume":"184","author":[{"given":"Amy A","family":"Herrold","sequence":"first","affiliation":[{"name":"Research Service & Center for Innovation and Complex Chronic Healthcare, Edward Hines Jr., VA Hospital, 5000 S 5th Ave, MC 151 H, Hines, IL"},{"name":"Department of Psychiatry and Behavioral Sciences, Northwestern University, Feinberg School of Medicine, 710 N Lakeshore Dr., Chicago, IL"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bridget","family":"Smith","sequence":"additional","affiliation":[{"name":"Research Service & Center for Innovation and Complex Chronic Healthcare, Edward Hines Jr., VA Hospital, 5000 S 5th Ave, MC 151 H, Hines, IL"},{"name":"Department of Pediatrics, Northwestern University, Feinberg School of Medicine, 310 E.
