Objective: To examine the functioning of military service members 5 years after completing a randomized controlled trial (RCT) of cognitive rehabilitation for mild traumatic brain injury (mTBI).
Setting: Home-based telephonic interview and internet-based self-ratings.
Participants: Sixty-nine of the 126 (55%) active-duty service members who were enrolled in a 4-arm RCT of cognitive rehabilitation 3 to 24 months after mTBI and were successfully contacted by phone 5 years later.
Objective: The study objective was to determine whether number of concussions would affect symptom improvement following cognitive rehabilitation (CR) interventions.
Method: Service members (N = 126) with concussion history completed a 6-week randomized control trial of CR interventions. Participants were stratified based on self-reported lifetime concussion frequency.

Methods: Neuropsychometric profiles of 349 individuals in the TBI Model Systems National Database were examined 4 weeks post-TBI (±2 weeks).
Purpose/objective: Effective treatment for postconcussive symptoms (PCS) immediately following mild traumatic brain injury (mTBI) includes reassurance, support, education about mTBI, and symptom management. However, effective treatments for chronic postconcussive-like symptoms, particularly with mental health comorbidities, remain unclear. Research Method/Design: We conduct a critical review of the treatment literature for chronic PCS, present exemplar studies of two alternative treatment approaches (i.

Method: 126 SMs with a history of mTBI 3 to 24 months postinjury participated in a randomized clinical trial of one of four, 6-week treatment arms: (a) psychoeducation, (b) computer-based CR, (c) therapist-directed manualized CR, and (d) therapist-directed CR integrated with cognitive-behavioral psychotherapy. Practice-adjusted reliable change scores (RCS) were calculated for the three primary outcome measures: Paced Auditory Serial Addition Test (PASAT), Symptom Checklist-90 Revised (SCL-90-R) Global Severity Index (GSI), and Key Behaviors Change Inventory (KBCI).
Population-based post-deployment screening programs within the Departments of Defense and Veterans Affairs have been implemented to assess for mental health conditions and traumatic brain injury. The purpose of this paper is to systematically review the literature on post-deployment screening within this context and evaluate evidence compared to commonly accepted screening implementation criteria. Findings reflected highly variable psychometric properties of the various screens, variable treatment referral rates following screening, low to moderate treatment initiation rates following screening, and no information on treatment completion or long-term outcomes following screening.

Objective: To examine differences in objective neurocognitive performance and subjective cognitive symptoms in individuals with a history of a single concussion, multiple concussions, orthopedic injuries, and posttraumatic stress disorder (PTSD).
Method: Participants included 116 military service members who sustained a mild traumatic brain injury (mTBI) during combat deployment. Subjects were subdivided into groups based on concussion frequency: a single concussion (n = 42), 2 concussions (n = 21), and 3 or more concussions (n = 53).
Objectives: To examine (a) generalization of the effectiveness of prolonged exposure (PE) therapy for posttraumatic stress disorder (PTSD) in improving postconcussive symptoms (PCSs) and other outcomes in military service members and Veterans (VA) with histories of mild to severe traumatic brain injury (TBI), and (b) factors associated with PCS reduction.
Setting: VA polytrauma medical center.
Participants: Consecutive referrals for PTSD treatment of Active Duty (n = 17) or Veterans (n = 27) diagnosed with PTSD and TBI (N = 44).
We sought to further define the epidemiology of the complex, multiple injuries collectively known as polytrauma/blast-related injury (PT/BRI). Using a systems science approach, we performed Bayesian network modeling to find the most accurate representation of the complex system of PT/BRI and identify key variables for understanding the subsequent effects of blast exposure in a sample of Florida National Guard members (1,443 deployed to Operation Enduring Freedom/Operation Iraqi Freedom and 1,655 not deployed) who completed an online survey during the period from 2009 to 2010. We found that postdeployment symptoms reported as present at the time of the survey were largely independent of deployment per se.

In contrast to concerns that cognitive limitations and neurobehavioral symptoms (NBS) associated with traumatic brain injury (TBI) may inhibit treatment effectiveness, a recent study found prolonged exposure (PE) led to large reductions in posttraumatic stress disorder (PTSD) symptoms among Iraq-Afghanistan veterans with a range of TBI severity (article by Wolf, Kretzmer, Crawford, Thors, Wagner, Strom, Eftekhari, Klenk, Hayward, and Vanderploeg [J Trauma Stress 28:339-347, 2015]). We further examined this sample of 69 veterans to determine whether system, veteran, and therapist factors predicted clinically significant responses. Results of hierarchical, logistic regressions revealed that therapist training in PE and lower service connection were associated with increased odds of large decreases in PTSD symptoms after adjusting for the robust effect of PE sessions completed.

Setting: Military medical center.
Participants: A total of 126 service members who received mTBI from 3 to 24 months before baseline evaluation and reported ongoing cognitive difficulties.
Objective: To examine the utility of the Neurobehavioral Symptom Inventory (NSI)-a measure of postconcussion symptoms used within the Veterans Health Administration-as an index of rehabilitation outcome.
Setting: Veterans Administration Polytrauma Rehabilitation Centers Traumatic Brain Injury (TBI) Model Systems program.
Participants: A total of 159 Veterans (14% with mild TBI; 86% with moderate-severe TBI).
The current investigation is a replication and extension of a previously published study by Cooper, Vanderploeg, Armistead-Jehle, Lewis, and Bowles (2014) demonstrating that performance validity test scores accounted for more variance in cognitive testing among service members with a history of concussion than did demographic variables, etiology of and time since injury, and symptom severity. The present study included a sample of 142 active-duty service members evaluated following a suspected or confirmed history of mild traumatic brain injury. Participants completed a battery of neuropsychological measures that included scales of performance and symptom validity (specifically the Medical Symptom Validity Test, Nonverbal Medical Symptom Validity Test, and Personality Assessment Inventory).

Methods: All studies of the VHA's screening and evaluation process were reviewed, both those involving primary data collection and those relying upon VHA data. Diagnostic statistics were summarized and also recalculated on the basis of a positive screening rate of 20%, the observed rate within the VHA, and an estimated population prevalence of TBI of 15% within the Department of Veterans Affairs (VHA).
The present study used archival clinical data to analyze the delivery and effectiveness of prolonged exposure (PE) and ancillary services for posttraumatic stress disorder (PTSD) among Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn veterans (N = 69) with histories of mild to severe traumatic brain injury (TBI). Data from standard clinical assessments of veterans and active duty personnel treated in both inpatient and outpatient programs at 2 Department of Veteran Affairs medical centers were examined. Symptoms were assessed with self-report measures of PTSD (PTSD Checklist) and depression (Beck Depression Inventory-II) before and throughout therapy.

Background: Given questions about "lower thresholds" for concussion, as well as possible effects of repetitive concussion and chronic traumatic encephalopathy (CTE), and associated controversy, there is increasing interest in "subconcussive" blows and their potential significance.
Objective: A formative review with critical examination of the developing literature on subconcussive blows in athletes with an emphasis on clinical outcomes.
Methods: Studies of biomechanical, performance and/or symptom-based, and neuroimaging data were identified via PubMed search and critically reviewed.
The objective of this study was to investigate the effectiveness of a web-based educational intervention for reducing postconcussion symptoms. 158 participants with self-reported symptomatic mild traumatic brain injury were randomized to intervention versus control. There was no effect of intervention on symptom severity or attributions.

Design: Criterion-standard.
Setting: Veterans Health Administration.
Objective: To investigate unique factors that affect health-related quality of life (QOL) in individuals with military deployment-related traumatic brain injury (MDR-TBI) and to develop appropriate assessment tools, consistent with the TBI-QOL/PROMIS/Neuro-QOL systems.
Participants: Three focus groups from each of the 4 Veterans Administration (VA) Polytrauma Rehabilitation Centers, consisting of 20 veterans with mild to severe MDR-TBI, and 36 VA providers were involved in early stage of new item banks development. The item banks were field tested in a sample (N = 485) of veterans enrolled in VA and diagnosed with an MDR-TBI.
