STEP-Home transdiagnostic group reintegration workshop to improve mental health outcomes for post-9/11 Veterans: Design, methods, and rationale for a randomized controlled behavioral trial.

BACKGROUND: Many post-9/11 U.S. combat Veterans experience difficulty readjusting to civilian life after military service, including relationship problems, reduced work productivity, substance misuse, and increased anger control problems. Mental health problems are frequently cited as causing these difficulties, driven by unparalleled rates of mild traumatic brain injury, posttraumatic stress, and other co-occurring emotional and physical conditions. Given the high prevalence of multimorbidity in this cohort, acceptable, non-stigmatizing, transdiagnostic interventions targeting reintegration are needed. The STEP-Home reintegration workshop has the potential to significantly improve skills to foster civilian reintegration, increase engagement in VA services, and improve mental health outcomes in Veterans with and without diagnosed clinical conditions. METHODS/DESIGN: Ongoing from 2019, a prospective, two-site, randomized trial of 206 post-9/11 U.S. military Veterans randomized to receive either 12 sessions of the STEP-Home transdiagnostic reintegration workshop (SH; Active Intervention) or Present Centered Reintegration Group Therapy (PCRGT; Active Control Intervention). Primary outcomes are reintegration, anger, and emotional regulation post-intervention and at 3-months post-intervention. Secondary outcomes include measures of mental health, functional and vocational status, and cognition. CONCLUSION: This study addresses an important gap in transdiagnostic interventions to improve civilian reintegration in post-9/11 Veterans. STEP-Home is designed to promote treatment engagement and retention, opening the door to critically needed VA care, and ultimately reducing long-term healthcare burden of untreated mental health illness in U.S. Veterans.

Importance of validity testing in psychiatric assessment: evidence from a sample of multimorbid post-9/11 veterans.

OBJECTIVE: Performance validity (PVTs) and symptom validity tests (SVTs) are necessary components of neuropsychological testing to identify suboptimal performances and response bias that may impact diagnosis and treatment. The current study examined the clinical and functional characteristics of veterans who failed PVTs and the relationship between PVT and SVT failures. METHOD: Five hundred and sixteen post-9/11 veterans participated in clinical interviews, neuropsychological testing, and several validity measures. RESULTS: Veterans who failed 2+ PVTs performed significantly worse than veterans who failed one PVT in verbal memory (Cohen's d = .60-.69), processing speed (Cohen's d = .68), working memory (Cohen's d = .98), and visual memory (Cohen's d = .88-1.10). Individuals with 2+ PVT failures had greater posttraumatic stress (PTS; ß = 0.16; p = .0002), and worse self-reported depression (ß = 0.17; p = .0001), anxiety (ß = 0.15; p = .0007), sleep (ß = 0.10; p = .0233), and functional outcomes (ß = 0.15; p = .0009) compared to veterans who passed PVTs. 7.8% veterans failed the SVT (Validity-10; ≥19 cutoff); Multiple PVT failures were significantly associated with Validity-10 failure at the ≥19 and ≥23 cutoffs (p's < .0012). The Validity-10 had moderate correspondence in predicting 2+ PVTs failures (AUC = 0.83; 95% CI = 0.76, 0.91). CONCLUSION: PVT failures are associated with psychiatric factors, but not traumatic brain injury (TBI). PVT failures predict SVT failure and vice versa. Standard care should include SVTs and PVTs in all clinical assessments, not just neuropsychological assessments, particularly in clinically complex populations.

Inhibitory control and alcohol use history predict changes in posttraumatic stress disorder symptoms.

OBJECTIVE: Posttraumatic stress disorder (PTSD) is associated with significant disability and can become chronic. Predictors of PTSD symptom changes over time, especially in those with a PTSD diagnosis, remain incompletely characterized. METHOD: In the present study, we examined 187 post-9/11 veterans (Mage = 32.8 years, 87% male) diagnosed with PTSD who performed two extensive clinical and cognitive evaluations approximately 2 years apart. RESULTS: We found that greater PTSD symptom reductions over time were related to lower lifetime drinking history and better baseline inhibitory control ability (Color-Word Inhibition and Inhibition/Switching), though not performance on other executive function tasks. Further, groups with reliably Improved, Worsened, or Chronic PTSD symptoms demonstrated significant differences in baseline inhibitory control and lifetime drinking history, with marked drinking differences starting in the early-to-mid 20s. We also found that PTSD symptom changes showed little-to-no associations with changes in inhibitory control or alcohol consumption. CONCLUSIONS: Together, these findings suggest that, in those diagnosed with PTSD, inhibitory control and alcohol use history reflect relatively stable risk/resiliency factors predictive of PTSD chronicity.

Diagnostic Accuracy of the Boston Assessment of Traumatic Brain Injury-Lifetime Clinical Interview Compared to Department of Defense Medical Records.

INTRODUCTION: Since 2006, efforts have been made to increase the accurate identification of traumatic brain injuries (TBIs) in post-9/11 military personnel. The Boston Assessment of TBI-Lifetime (BAT-L) is the first validated instrument designed specifically to diagnose TBIs throughout the life span in post-9/11 Veterans. The objective was to compare the diagnostic accuracy of the BAT-L with medical records from the Department of Defense (DoD). MATERIAL AND METHODS: Traumatic brain injury diagnosis for 153 Veterans deployed in 2011 enrolled in the Translational Research Center for TBI and Stress Disorder longitudinal cohort study from the BAT-L clinical interview was compared to DoD online medical records to determine diagnostic prevalence and injury severity for all head injury cases during deployment. Sensitivity, specificity, Cohen's kappa, and Kendall's tau-b were calculated for TBI diagnosis and severity. Concordant TBI cases and discordant TBI cases were compared using chi-square and t-test analyses. This study has been approved by VA Boston by Institutional Review Boards for human participants' protection. RESULTS: Correspondence of TBI diagnoses from the BAT-L with DoD records was fair (κ = 0.42; sensitivity = 72.7%; specificity = 82.8%). Comparison of injury severity also showed fair correspondence (κ = 0.41). Missing TBI diagnostic data from DoD records were frequent; 43% of TBIs reported on the BAT-L did not have any documentation of assessment or diagnoses in DoD records. CONCLUSION: This study addresses a critical gap in research by comparing the diagnostic accuracy of a validated, semi-structured clinical interview with available medical records. Diagnosis of TBIs via the BAT-L was both sensitive and specific when compared to DoD records, supporting the validity of the BAT-L for retrospective assessment of military TBI. However, diagnostic correspondence was only fair. This lack of diagnostic agreement was related to multiple factors including lack of documentation at the time of injury by DoD, differences in assessment and goals, and other combat-related motivational factors associated with failure to report injuries while deployed. Several policies have been implemented to address underreporting and under-documentation of TBIs, yet challenges remain. Recommendations for evaluating TBI are presented. Accurate diagnosis of TBI is necessary for appropriate treatment planning, as well as service-related compensation.

Contributory Etiologies to Cognitive Performance in Multimorbid Post-9/11 Veterans: The Deployment Trauma Phenotype.

OBJECTIVE: This study examined cognitive functioning in post-9/11 Veterans with the deployment trauma phenotype (DTP), comprised of co-occurring diagnoses of depressive disorder (major depressive disorder and or persistent depressive disorder/dysthymia), posttraumatic stress disorder (PTSD), and mild traumatic brain injury (mTBI), using objective neuropsychological measures. METHOD: Participants included a cross-sectional sample of 399 post-9/11 Veterans who completed clinical interviews and neuropsychological tests as part of a larger study at VA Boston Healthcare System. Confirmatory factor analysis identified four cognitive domains: attention, cognitive control/processing speed, episodic memory, and cognitive flexibility. Veterans with DTP and its constituent diagnoses in isolation, two-way diagnostic combinations, and no constituent diagnoses were compared. RESULTS: Veterans with DTP had a twofold increased prevalence for below average performance in cognitive control/processing speed compared with those with no constituent diagnoses (prevalence ratios [PRs] = 2.04; 95% confidence interval [CI]: 1.03-4.05). The PTSD + depressive disorder group also had a twofold increased prevalence for below average performance in episodic memory (PR = 2.16; 95% CI: 1.05-4.43). CONCLUSIONS: The deployment trauma phenotype is associated with clinically significant decrease in cognitive control/processing speed in post-9/11 Veterans. Comorbid PTSD and depressive disorder negatively impacted performances in episodic memory. Mild TBI alone showed no cognitive deficits. Clinical interventions should target psychiatric symptoms with a transdiagnostic approach to address this multimorbid population.

Post-traumatic stress disorder and depression are uniquely associated with disability and life dissatisfaction in post-9/11 veterans.

Veterans who served in post-9/11 conflicts and experience deployment trauma sequelae frequently endorse disability and dissatisfaction with life. Although correlated, disability and life dissatisfaction represent distinct constructs with separate implications for quality of life. We examined associations between deployment trauma sequelae, disability and life dissatisfaction in 288 post-9/11 Veterans. Participants completed assessments of psychiatric, somatic and social functioning. Self-reports evaluating disability and life dissatisfaction were used to group participants based on established criteria (i.e., Disability and Dissatisfaction, Disability Only, Dissatisfaction Only, or No Disability or Dissatisfaction). Multinomial logistic regressions revealed that greater post-traumatic stress disorder (PTSD) and depressive symptom severity were independently associated with increased odds of being in the Disability and Dissatisfaction group, the Disability Only group and the Dissatisfaction Only group, relative to the No Disability or Dissatisfaction group. Number of prior mild traumatic brain injuries (mTBI) was not associated with disability or dissatisfaction after accounting for other trauma sequelae. Social support attenuated the relationship between depression and membership in the Disability and Dissatisfaction group. Participants who reported greater dissatisfaction than disability endorsed greater depression and mTBI frequency. Overall, PTSD and depression convey a heightened risk of both disability and life dissatisfaction, while social support may be protective.

Online Telehealth Delivery of Group Mental Health Treatment Is Safe, Feasible, and Increases Enrollment and Attendance in Post-9/11 U.S. Veterans.

Post-9/11 U.S. veterans are clinically complex with multiple co-occurring health conditions that lead to increased morbidity and mortality, risk for suicide, and decreased quality of life, but underutilization and resistance to treatment remain significant problems. Increased isolation and decreased community and social support due to coronavirus disease (COVID-19) have exacerbated mental health risk. This study evaluated the safety and feasibility of home-based telemental health group workshops to improve reintegration and social connection in post-9/11 U.S. military personnel. Seventy-four (61 males/13 females) post-9/11 U.S. military veterans were randomized to receive 12 sessions of STEP-Home cognitive-behavioral group workshop or present-centered group therapy. Treatment was delivered either in person (traditional medical center setting, treatment as usual [TAU]), or via home-based synchronous videoconferencing (VC). The change to VC occurred due to social distancing guidelines during COVID-19. Mean age was 41.0 years (SD = 11.5, range 24-65). Forty-five (36 males/9 females) participated in VC and 29 (25 males/4 females) in TAU. Demographics were similar across treatment milieu. There were no differences in therapist treatment adherence for TAU versus VC. Therapist satisfaction was higher for TAU groups (q value < .05). Veterans showed higher enrollment, attendance, group cohesion, and veteran-to-veteran support for VC compared to TAU (q values < .05). Safety procedures were successfully implemented via VC. Results demonstrate the safety, feasibility, and high satisfaction of group telemental health in U.S. veterans. Higher enrollment and treatment adherence for telemental health delivery resulted in a greater likelihood of receiving an effective treatment dose than TAU. Strong group cohesion and veteran-to-veteran support were achievable via telehealth. Telemental health offers convenient, efficient, and cost-effective care options for veterans and may be particularly helpful for patients with high psychiatric burden.

The Boston Assessment of Traumatic Brain Injury-Lifetime Semistructured Interview for Assessment of TBI and Subconcussive Injury Among Female Survivors of Intimate Partner Violence: Evidence of Research Utility and Validity.

OBJECTIVE: To adapt the Boston Assessment of TBI-Lifetime (BAT-L) interview specifically for female survivors of intimate partner violence (IPV), validate the adapted BAT-L/IPV, and report the prevalence of head injury. SETTING: The BAT-L is the first validated instrument to diagnose traumatic brain injuries (TBIs) throughout the life span for post-9/11 veterans. The BAT-L/IPV was adapted to target diagnostic issues belonging exclusively to IPV while maintaining its life span approach. PARTICIPANTS: Community-dwelling convenience sample of 51 female survivors of IPV with subthreshold (n = 10) or full diagnostic criteria (n = 41) of posttraumatic stress disorder. DESIGN: Standard TBI criteria were evaluated using a semistructured clinical interview. MAIN MEASURES: The BAT-L/IPV is compared with the Ohio State University TBI Identification Method (OSU-TBI-ID) scoring approach as the criterion standard. RESULTS: Correspondence between the BAT-L/IPV and the OSU-TBI-ID score was excellent (Cohen κ = 0.86; Kendall τ-b = 0.89). Sensitivity = 89.3% (95% CI, 81.2-97.4); specificity = 98.3% (95% CI, 95.0-100); positive predictive value = 98.0% (95% CI, 94.2-100); and negative predictive value = 90.6% (95% CI, 83.5-97.7). On the BAT-L/IPV, more than one-third (35.3%) of IPV survivors reported TBI secondary to an IPV-related assault, 76.5% reported IPV subconcussive head injury, 31.4% reported attempted strangulation, and 37.3% reported non-IPV TBI. CONCLUSIONS: The BAT-L/IPV performed well in diagnosing TBI in female IPV survivors as compared with the criterion standard. The prevalence of TBI was frequent; subconcussive head injury was pervasive. Greater awareness for head injury risk and increased diagnostic specificity of TBI in IPV survivors is needed.
