Abstract Objective The study investigated the relationship between levels of symptom reporting and performance validity testing (PVT) in Active Duty Service Members (ADSM) with mild traumatic brain injury (mTBI). Method A total of 70 ADSM with a history of mTBI completed the Neurobehavioral Symptom Inventory (NSI); the PTSD Check List for DSM-5 (PCL-5), Headache Impact Test (HIT-6), Patient Health Questionnaire (PHQ8), Pittsburgh Sleep Quality Index (PSQI), and Alcohol Use Disorders Identification Test (AUDIT-C); and a comprehensive neuropsychological evaluation including the Test of Memory Malingering (TOMM). A multiple regression was conducted with all self-reported symptom questionnaires as predictors of PVT performance. To further explore this relationship, the four NSI subscales (affective, cognitive, vestibular, somatosensory) plus the mild Brain Injury Atypical Symptoms (mBIAS) subscore were entered into a separate regression analysis. Results The NSI was the only significant predictor of TOMM Trial 1 performance (TOMMT1; R2 = .272, F(6,58) = 3.606, p < .01; β = −.615, p > .01). When the four NSI subscales (affective, cognitive, vestibular, somatosensory) plus the mild Brain Injury Atypical Symptoms (mBIAS) subscore were entered into a separate regression analysis, only the somatosensory subscore emerged as a significant predictor of TOMMT1 (R2 = .208, F(5,63) = 3.317, p < .05; β = −.384, p > .05). Conclusions Results suggest that performance validity measures in ADSM with mTBI may at times be more strongly influenced by patients’ health concerns than by overt dissimulation.

Background:There is a high comorbidity of posttraumatic stress (PTS) and mild traumatic brain injury (mTBI), with largely overlapping symptomatology, in military service members.Objective:To examine white matter integrity associated with PTS and mTBI as assessed using diffusion tensor imaging (DTI).Method:Seventy-four active-duty U.S. soldiers with PTS (n = 16) and PTS with co-morbid history of mTBI (PTS/mTBI; n = 28) were compared to a military control group (n = 30). Participants received a battery of neurocognitive and clinical symptom measures. The number of abnormal DTI values was determined (>2 SDs from the mean of the control group) for fractional anisotropy (FA) and mean diffusivity (MD), and then compared between groups. In addition, mean DTI values from white matter tracts falling into three categories were compared between groups: (i) projection tracts: superior, middle, and inferior cerebellar peduncles, pontine crossing tract, and corticospinal tract; (ii) association tracts: superior longitudinal fasciculus; and (iii) commissure tracts: cingulum bundle (cingulum-cingulate gyrus and cingulum-hippocampus), and corpus callosum.Results:The comorbid PTS/mTBI group had significantly greater traumatic stress, depression, anxiety, and post-concussive symptoms, and they performed worse on neurocognitive testing than those with PTS alone and controls. The groups differed greatly on several clinical variables, but contrary to what we hypothesized, they did not differ greatly on primary and exploratory analytic approaches of hetero-spatial whole brain DTI analyses.Conclusion:The findings suggest that psychological health conditions rather than pathoanatomical changes may be contributing to symptom presentation in this population.

Abstract Objective Examine factors associated with history of arrests and felony incarceration among Veterans and Service Members (V/SM) with combat exposure. Method Participants were V/SM who completed a baseline assessment for the multicenter Chronic Effects of Neurotrauma Consortium study (N = 1555). Most were male (87%), white (72%), with a mean age of 40 years (SD = 9.71). The majority (83%) reported a history of ≥1 mild traumatic brain injury (mTBI), with thirty-five present of those experiencing 3+ mTBIs. Results Three groups were composed based on self-reported level of involvement with the criminal justice system: 1.) No history of arrests or incarcerations (65%), 2.) A lifetime history of arrest but no felony incarceration (32%), and 3.) A lifetime history of felony incarceration (3%). Chi-square and Kruskal-Wallis H tests revealed statistically significant differences between the groups in demographic factors including the incarcerated group having younger age, greater percentage of men, lower education, and greater percentage of never being married, followed by the arrest group and then the no arrest group (all p < 0.05). The incarcerated group also had the highest level of posttraumatic stress disorder (PTSD) symptoms, lowest social support, and greatest percentage of hazardous alcohol consumption, followed by the arrest and then the no arrest groups (all p < 0.05). No differences were found between groups for mTBI history or neuropsychological testing results. Conclusions Correlates of legal involvement among V/SM span demographic and psychological dimensions. Some correlates are modifiable, including social support, PTSD symptoms, and alcohol consumption. Addressing these modifiable risk factors is critical to lower the risk of future criminal justice involvement.
