A systematic review of suicidal ideation and behaviors among adults with spinal cord injury.

CONTEXT: Suicide is a public health crisis within the United States. Individuals with spinal cord injury (SCI) are vulnerable to negative outcomes such as suicide. OBJECTIVE: This systematic review describes frequency of suicidal ideation (SI) and behaviors (suicide attempt [SA] and deaths) among samples of adults living with SCI. Associated risk and protective factors of SI and suicidal behaviors were also explored. METHODS: On July 7, 2021, OVID Medline, EMBASE, OVID PsycINFO, Web of Science Core Collection, CINAHL, Cochrane Library, and Google Scholar databases were searched for SI, SA, and deaths by suicide among adults with a history of SCI. Risk of bias (RoB) was assessed using the Effective Public Health Practice Project (EPHPP) quality assessment tool. Results were synthesized descriptively considering the likely impact of RoB. The updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 reporting method was used. RESULTS: Sixty-nine articles were included. Frequency of SI and SAs within study samples ranged from 4% to 67%, and 0% to approximately 66%, respectively. While assessment methods for SI and SA widely varied, suicide deaths data sources were more consistent. Studies assessing SI and SA generally had high RoB and the overall strength of evidence was low. Stronger observational study designs assessing death by suicide had low RoB and the overall strength of evidence was high. Very few studies examined protective factors. DISCUSSION: Findings support previous work. Quality of evidence, and therefore confidence in the frequency of these outcomes, was impacted by the use of assessment measures without sufficient psychometric properties. The field will benefit from use of psychometrically sound measures to assess for SI, SA and suicide deaths. Furthermore, additional work is needed to elucidate risk and protective factors and to clearly characterize samples to increase generalizability of findings to the larger SCI community, including standardized reporting of SCI characteristics (e.g. use of American Spinal Injury Association classification system). Ultimately, improved suicide assessment and risk management is expected to prevent suicide among those living with SCI. REGISTRATION: CRD42020164686.

Association between perceived distress and salivary cortisol in veterans with mTBI.

Mild traumatic brain injury (mTBI) is one of the most common injuries experienced by Veterans and can frequently result in a variety of post-concussive symptoms. Post-concussive headaches (PCH), one of the most common symptoms, can persist for years after the injury occurred. The long-lasting impacts of PCH can be extremely distressing for Veterans, thus necessitating the need to find reliable biomarkers that directly relate to subjective feelings of distress. Yoga-based interventions have been shown to improve both subjective and objective markers of stress. Techniques used in yoga, such as the focus on releasing muscular tension, are also recommended as strategies for treating PCH. Thus, yoga-based interventions provide a unique context for the comparison of subjective and objective measures of distress in Veterans with PCH. In this secondary, exploratory analysis, we examined the relationship between perceived distress and cortisol in sixteen Veterans with mTBI and long-term PCH within the context of a yoga intervention feasibility study. The Visual Analogue Scale (VAS), a validated tool for measuring subjective distress, was administered to participants immediately before and after 75-min yoga classes, which occurred twice weekly over eight weeks. Participants also provided salivary cortisol (pre- and post-yoga) at in-person sessions (eight) to compare to changes in VAS scores. We found that VAS scores were significantly reduced within five of the eight assessed yoga classes, but there were no significant changes in cortisol levels. No significant correlations were found between VAS scores and salivary cortisol levels. When looking at how cortisol levels changed over time (i.e., over the series of eight yoga sessions), there was a significant downward trajectory in post-yoga cortisol, but not after taking pre-class cortisol into account (i.e., within yoga session cortisol change over time). Taken together, we found that subjective distress, but not cortisol was reduced by yoga classes. These data suggest that salivary cortisol did not match changes in perceived distress, thus emphasizing the ongoing challenges of relating subjective and objective measures.

Validation of a Computerized Adaptive Test Suicide Scale (CAT-SS) among United States Military Veterans.

To validate the Computerized Adaptive Test Suicide Scale (CAT-SS), Veterans completed measures at baseline (n = 305), and 6- (n = 249), and 12-months (n = 185), including the CAT-SS (median items 11, duration of administration 107 seconds) and the Columbia-Suicide Severity Rating Scale (C-SSRS). Logistic regression was used to relate CAT-SS scores (baseline) to C-SSRS assessed outcomes (active ideation with plan and intent; attempt; interrupted, aborted or self-interrupted attempt, or preparatory acts or behaviors; all outcomes combined). A mixed-effects logistic regression model was used to evaluate the relationship between the lagged CAT-SS scores and outcomes (6- and 12-months). The baseline CAT-SS demonstrated predictive accuracy for all outcomes at 6-months, and similar results were found for baseline and all outcomes at and through 12-months. Longitudinal analysis revealed for every 10-point change in the CAT-SS there was a 50-77% increase in the likelihood of suicide-related outcomes. The CAT-SS demonstrated added value when compared to current suicide risk prediction practices.

Met and unmet rehabilitative needs among pediatric patients with moderate to severe TBI.

OBJECTIVE: Estimate the probability of met and unmet post-acute rehabilitative needs among pediatric patients with moderate to severe traumatic brain injury (TBI). PARTICIPANTS: One hundred and thirty children who received acute and post-acute rehabilitative services at a hospital for children. METHODS: Prospective, observational study. Recommended service needs (1. Medical, 2. Psychological, 3. Cognitive/Educational, 4. Medically Based Therapies, 5. Community/Caregiver/Family Support) were collected at discharge and 1, 6, 12, and 18 months post-injury. Probabilities were estimated using nonlinear logistic regression models. The impact of age at discharge was also assessed. RESULTS: Over time, the estimated probability of need for Medical, Medically Based Therapies, and Cognitive/Educational services were consistently high. Whereas unmet need for Medical and Medically Based Therapies were low, unmet need for Cognitive/Educational services were relatively high. Need for Psychological and Community/Caregiver/Family Support services increased in the months post-discharge, as did the probability of unmet need. Older age at discharge was associated with need for Psychological and Community/Caregiver Family Support services. CONCLUSIONS: Findings support the long-term monitoring of need for Psychological and Community/Caregiver/Family Support services among children with moderate to severe TBI. Future research to explore the etiology of unmet needs is warranted.

Development and Validation of Computerized Adaptive Assessment Tools for the Measurement of Posttraumatic Stress Disorder Among US Military Veterans.

Importance: Veterans from recent and past conflicts have high rates of posttraumatic stress disorder (PTSD). Adaptive testing strategies can increase accuracy of diagnostic screening and symptom severity measurement while decreasing patient and clinician burden. Objective: To develop and validate a computerized adaptive diagnostic (CAD) screener and computerized adaptive test (CAT) for PTSD symptom severity. Design, Setting, and Participants: A diagnostic study of measure development and validation was conducted at a Veterans Health Administration facility. A total of 713 US military veterans were included. The study was conducted from April 25, 2017, to November 10, 2019. Main Outcomes and Measures: The participants completed a PTSD-symptom questionnaire from the item bank and provided responses on the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) (PCL-5). A subsample of 304 participants were interviewed using the Clinician-Administered Scale for PTSD for DSM-5. Results: Of the 713 participants, 585 were men; mean (SD) age was 52.8 (15.0) years. The CAD-PTSD reproduced the Clinician-Administered Scale for PTSD for DSM-5 PTSD diagnosis with high sensitivity and specificity as evidenced by an area under the curve of 0.91 (95% CI, 0.87-0.95). The CAT-PTSD demonstrated convergent validity with the PCL-5 (r = 0.88) and also tracked PTSD diagnosis (area under the curve = 0.85; 95% CI, 0.79-0.89). The CAT-PTSD reproduced the final 203-item bank score with a correlation of r = 0.95 with a mean of only 10 adaptively administered items, a 95% reduction in patient burden. Conclusions and Relevance: Using a maximum of only 6 items, the CAD-PTSD developed in this study was shown to have excellent diagnostic screening accuracy. Similarly, using a mean of 10 items, the CAT-PTSD provided valid severity ratings with excellent convergent validity with an extant scale containing twice the number of items. The 10-item CAT-PTSD also outperformed the 20-item PCL-5 in terms of diagnostic accuracy. The results suggest that scalable, valid, and rapid PTSD diagnostic screening and severity measurement are possible.

Strength and awareness in action: Feasibility of a yoga-based intervention for post-acute mild TBI headaches among veterans.

BACKGROUND: Mild traumatic brain injury (mTBI) is a signature injury sustained by Veterans during recent conflicts. For some, mTBI/concussion is associated with disabling symptoms, including post-concussive headaches (PCH). However, there are limited evidence-based treatments for persistent PCH. OBJECTIVE: Investigators assessed the feasibility of design elements of a yoga-based interventional trial for PCH among Veterans, as well as the acceptability of the intervention. METHODS: This randomized controlled acceptability and feasibility trial was implemented using a waitlist-control design. Design elements of interest included: an exercise run-in class; recruitment and retention strategies; and, ecological momentary assessment (EMA) modalities to track headaches and yoga practice. Veteran satisfaction regarding the intervention was also evaluated. A descriptive analysis was conducted on candidate outcomes including PCH, post-concussive symptoms, pain, and daily functioning. RESULTS: Twenty-seven participants (out of 70 consented and eligible after Study Visit 1) completed each evaluation timepoint and regularly attended yoga sessions, with 89% of these Veterans reporting moderate to high levels of satisfaction with the intervention at study completion. Qualitatively, participants endorsed improvements in headaches, chronic pain, and mood. Feasibility results were mixed. Initial feasibility criterion regarding yoga attendance was not met; however, modifications, such as expansion to an additional clinic site and reduction of in-person yoga sessions with increased encouragement to use study-created online yoga videos improved feasibility of the study design. Participants most frequently used mobile and web-based EMA modalities to track yoga practice. CONCLUSIONS: Although challenges with feasibility of the study design elements were noted, results suggested acceptability of the yoga-based intervention for Veterans with persistent PCH. Additional exploration regarding the frequency and modality of yoga delivery (e.g., in-person, telehealth) is warranted. IMPACT: Veterans found the yoga-based intervention acceptable, however exploration of novel modalities of intervention delivery will likely be necessary to enhance the feasibility of intervention implementation during future trials.

Acceptability of cognitive anxiety sensitivity treatment among veterans with mTBI.

OBJECTIVE: Anxiety sensitivity (AS) is a transdiagnostic risk factor for persistent physical and psychological symptoms relevant to veterans, such as postconcussive symptoms following mild traumatic brain injury (mTBI). The Cognitive Anxiety Sensitivity Treatment (CAST) computerized intervention has been shown to reduce AS but has not been widely used among veterans. The purpose of this study was to assess the acceptability and feasibility of CAST among veterans with elevated AS and mTBI eligible to receive Veterans Health Administration (VHA) care. DESIGN: Twenty-two veterans with mTBI, elevated cognitive AS, and history of deployment to Iraq and/or Afghanistan completed a single assessment and intervention session. Acceptability was assessed with the Client Satisfaction Quesitonnaire-8 (CSQ-8) and a qualitative interview. Measures of feasibility included study enrollment, ease of participation, and intervention completion. AS was assessed pre- and post-CAST completion. RESULTS: Consistent with interview responses, 77.3% of participants' CSQ-8 scores indicated that veterans found the intervention acceptable. Technological issues, such as internet connectivity, decreased feasibility of consistently delivering the intervention in the research setting readily available to the study team. Decreases on pre-to-post intervention AS outcomes were observed. CONCLUSIONS: Acceptability of the CAST intervention in this sample was generally supported. Feasibility of implementing CAST in this study was limited by technological issues. Data did not indicate a critical need to revise content of the CAST intervention. Identified strategies for increasing the feasibility of future research and clinical implementation of CAST are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Mobile App for Mental Health Monitoring and Clinical Outreach in Veterans: Mixed Methods Feasibility and Acceptability Study.

BACKGROUND: Advances in mobile health (mHealth) technology have made it possible for patients and health care providers to monitor and track behavioral health symptoms in real time. Ideally, mHealth apps include both passive and interactive monitoring and demonstrate high levels of patient engagement. Digital phenotyping, the measurement of individual technology usage, provides insight into individual behaviors associated with mental health. OBJECTIVE: Researchers at a Veterans Affairs Medical Center and Cogito Corporation sought to explore the feasibility and acceptability of an mHealth app, the Cogito Companion. METHODS: A mixed methodological approach was used to investigate the feasibility and acceptability of the app. Veterans completed clinical interviews and self-report measures, at baseline and at a 3-month follow-up. During the data collection period, participants were provided access to the Cogito Companion smartphone app. The mobile app gathered passive and active behavioral health indicators. Data collected (eg, vocal features and digital phenotyping of everyday social signals) are analyzed in real time. Passive data collected include location via global positioning system (GPS), phone calls, and SMS text message metadata. Four primary model scores were identified as being predictive of the presence or absence of depression or posttraumatic stress disorder (PTSD). Veterans Affairs clinicians monitored a provider dashboard and conducted clinical outreach when indicated. RESULTS: Findings suggest that use of the Cogito Companion app was feasible and acceptable. Veterans (n=83) were interested in and used the app; however, active use declined over time. Nonetheless, data were passively collected, and outreach occurred throughout the study period. On the Client Satisfaction Questionnaire-8, 79% (53/67) of the sample reported scores demonstrating acceptability of the app (mean 26.2, SD 4.3). Many veterans reported liking specific app features (day-to-day monitoring) and the sense of connection they felt with the study clinicians who conducted outreach. Only a small percentage (4/67, 6%) reported concerns regarding personal privacy. CONCLUSIONS: Feasibility and acceptability of the Cogito Corporation platform to monitor mental health symptoms, behaviors, and facilitate follow-up in a sample of veterans were supported. Clinically, platforms such as the Cogito Companion system may serve as useful methods to promote monitoring, thereby facilitating early identification of risk and mitigating negative psychiatric outcomes, such as suicide.

Characterization of lifetime TBIs in a cohort of recently deployed soldiers: The warrior strong study.

OBJECTIVE: To describe and characterize the lifetime history of traumatic brain injury (TBI) among active duty soldiers returning from deployment to Afghanistan or Iraq. METHOD: Data were extracted from a larger parent study that was conducted at two large United States Army bases between 2009 and 2014 during Post-Deployment Health Assessment. The sample included 1,060 soldiers who sustained at least one TBI during their lifetime. RESULTS: The Ohio State University TBI-Identification Method interview was administered to characterize individuals' total lifetime history of TBI. Soldiers reported sustaining a median of 2 lifetime TBIs. Slightly more than half of the sample without a most recent deployment-related TBI still reported a history of a lifetime TBI (some of which occurred during previous deployments). Most lifetime injuries reported were of mild severity; however, 6% of individuals reported a history of moderate/severe TBI. Blast was the most frequent mechanism associated with recent deployment-related mild TBIs. CONCLUSION: Findings suggest that soldiers who screened positive, as well as those who screened negative, for a history of TBI during their recent deployment still endorsed a lifetime history of TBI. Future research is needed to explore the functional impact of multiple TBIs over one's lifetime to help inform screening, assessment, and treatment among military personnel.

A Clinical Evidence-Based Approach to Examine the Effects of mTBI and PTSD Symptoms on ANAM Performance in Recently Deployed Active Duty Soldiers: Results From the Warrior Strong Study.

OBJECTIVE: Service members are frequently diagnosed with comorbid mild traumatic brain injury (mTBI) and posttraumatic stress disorder after returning from Afghanistan and Iraq. Little is known about how mTBI in the postacute and chronic phases combined with current posttraumatic stress disorder symptoms (PTS) affects performance on the Automated Neuropsychological Assessment Metrics, Version 4, Traumatic Brain Injury-Military (ANAM4) battery used by the US military. We examined postdeployment ANAM4 performance using conventional statistical methods, as well as rates of poor performance, below established cutoffs (<10th and ≤2nd percentile). METHODS: A total of 868 soldiers were assessed for history of mTBI during the most recent deployment, as well as, lifetime mTBI, current PTS, and current pain-related symptoms. The ANAM4 was also administered. RESULTS: Soldiers with PTS and/or mTBI performed worse on ANAM4 relative to controls with those with both conditions performing worst. However, a nontrivial minority (∼10%-30%) of individuals with mTBI, PTS, or both had scores that were at or below the second percentile. CONCLUSION: Our results illustrate that a combination of mTBI and PTS is associated with worse ANAM4 performance than either condition alone. Furthermore, only a minority of soldiers with any, or both, of the conditions had ANAM deficits. The long-lasting impacts and unique contribution of each condition have yet to be determined.

Soldiers returning from deployment: A qualitative study regarding exposure, coping, and reintegration.

PURPOSE/OBJECTIVE: The purpose of this study was to qualitatively explore exposure to deployment-related physical and/or emotional trauma and associated symptoms among Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) soldiers. Interviews also focused on in-theater- and reintegration-related experiences. RESEARCH METHOD/DESIGN: OEF/OIF soldiers (N = 103) participated in semistructured interviews, and a qualitative descriptive methodology was used to analyze the data. RESULTS: Themes were identified regarding (a) common experiences related to emotional and physical traumas and associated symptoms and strategies for coping and making meaning of experiences and (b) how combat and reintegration experiences affected soldiers' senses of self, relationships with others, and functioning. CONCLUSIONS/IMPLICATIONS: Themes identified support a rethinking of deployment-related mild traumatic brain injury and posttraumatic stress disorder as discrete conditions. Dimensional versus categorical models should be considered. The findings also highlight experiences and potentially meaningful constructs (e.g., moral injury, moral repair) that can be used to inform research and clinical efforts aimed at improving the lives of those who have served.

A Qualitative Study of Potential Suicide Risk Factors Among Operation Iraqi Freedom/Operation Enduring Freedom Soldiers Returning to the Continental United States (CONUS).

OBJECTIVE: A qualitative study among Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Soldiers was conducted to explore potential constructs underlying suicide according to the interpersonal-psychological theory of suicide (IPTS); these include burdensomeness, failed belonging, and acquired capability. METHODS: Qualitative semistructured interviews were conducted with 68 Soldiers at 3 months post-OEF/OIF deployment. Soldiers were asked about changes in their experiences of pain, burdensomeness, and lack of belonging. The methodology employed was descriptive phenomenological. RESULTS: Transcripts were reviewed and themes related to the IPTS constructs emerged. Soldiers' postdeployment transition experiences included higher pain tolerance, chronic pain, emotional reactivity, emotional numbing and distancing, changes in physical functioning, combat guilt, discomfort with care seeking, and difficulties reintegrating into family and society. CONCLUSIONS: Findings highlight the utility of the IPTS in understanding precursors to suicide associated with transition from deployment, as well as treatment strategies that may reduce risk in Soldiers during reintegration.

A factor analysis and exploration of attitudes and beliefs toward complementary and conventional medicine in veterans.

BACKGROUND: Although Veterans utilize complementary and alternative medicine (CAM) at rates comparable with civilians, little is known about Veterans' attitudes and beliefs toward CAM. Measures to increase such knowledge may help to identify treatment preferences, particularly among those with signature conditions from the recent conflicts [ie, traumatic brain injury (TBI), posttraumatic stress disorder (PTSD)]. OBJECTIVE: This exploratory study aimed to: (1) determine the factors of the Complementary, Alternative, and Conventional Medicine Attitudes Scale (CACMAS); and to utilize the resulting factors to describe (2) attitudes and beliefs toward CAM; (3) their association with TBI, PTSD, and history of self-directed violence. Patterns of CAM use were also obtained. RESEARCH DESIGN: Factor analysis. Observational study. SUBJECTS: Participants were 97 Veterans seeking care at a Mountain State Veterans Affairs Medical Center. METHODS: Participants completed the CACMAS, clinical interviews, and self-report measures during a single visit. RESULTS: CACMAS factors identified were: acceptability of (1) CAM and (2) conventional medicine; (3) mind-body integration; and (4) belief in CAM. Acceptability of CAM was significantly associated with history of mild TBI (mTBI) or PTSD symptom severity. Veterans endorsed a wide range of CAM use. CONCLUSIONS: Veterans in this sample were open to CAM and conventional medicine, believed in CAM, and believed that treatments should incorporate the mind and body. Veterans with a history of mTBI or PTSD symptoms may be more accepting of CAM. Understanding Veterans' beliefs and attitudes regarding CAM may help providers deliver patient-centered treatments, particularly among those with conditions for which evidence-based interventions are limited (eg, mTBI).

Self-report measures to identify post traumatic stress disorder and/or mild traumatic brain injury and associated symptoms in military veterans of Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF).

Individuals serving in Iraq and Afghanistan sustain injuries associated with physical and psychological trauma. Among such injuries, mild traumatic brain injury (mTBI) and post traumatic stress disorder (PTSD) are common. Self-report measures are frequently used to identify mTBI and/or PTSD and symptoms associated with these conditions. In addition to providing information regarding mTBI and PTSD, the goal of this literature review was to identify and present information on the psychometric properties of measures used to obtain information regarding these common conditions among Veterans who have returned from Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF). A comprehensive review of studies in which self-report measures were used to evaluate mTBI, PTSD, and associated symptoms among OEF/OIF Veterans is presented. Findings suggest that additional work is needed to identify psychometrically sound and clinically useful self-report measures that assess mTBI and PTSD and associated symptoms among OEF/OIF Veterans.

Implementation of a suicide nomenclature within two VA healthcare settings.

Suicide and suicide attempts are significant issues for military, Veterans Affairs (VA), and civilian healthcare systems. The lack of uniform terms related to self-directed violence (SDV) has inhibited epidemiological surveillance efforts, limited the generalizability of empirical studies of suicide and non-lethal forms of SDV, and complicated the implementation of evidence-based assessment and treatment strategies for individuals with suicidal thoughts and/or behaviors. The Department of Veterans Affairs recently adopted the Centers for Disease Control and Prevention's (CDC) SDV Classification System (SDVCS). This paper describes an implementation study of the SDVCS in two VA Medical Centers. The Veterans Integrated Service Network (VISN) 19 Mental Illness Research, Education and Clinical Center (MIRECC) training program for the SDVCS, including the SDVCS Clinical Tool (CT), will be discussed. Although preliminary data suggest that the CT and SDVCS are generally perceived as being acceptable and useful, further work will likely be required to facilitate widespread adoption. Potential next steps in this process are presented.

Posttraumatic stress disorder, traumatic brain injury, and suicide attempt history among veterans receiving mental health services.

History of posttraumatic stress disorder (PTSD) or traumatic brain injury (TBI) has been found to increase risk of suicidal behavior. The association between suicide attempt history among veterans with PTSD and/or TBI was explored. Cases (N = 81) and 2:1 matched controls (N = 160) were randomly selected from a Veterans Affairs Medical Center clinical database. PTSD history was associated with an increased risk for a suicide attempt (OR = 2.8; 95% CI: 1.5, 5.1). This increased risk was present for those with and without a history of TBI. Results support incorporating PTSD history when assessing suicide risk among veterans with and without TBI.

Postdeployment traumatic brain injury screening questions: Sensitivity, specificity, and predictive values in returning soldiers.

OBJECTIVE: To evaluate the sensitivity, specificity, and predictive values of Post-Deployment Health Assessment traumatic brain injury (TBI) screening questions employed by the Department of Defense (DOD). PARTICIPANTS: Complete data was obtained from 3,072 soldiers upon return from a 15-month deployment to Iraq. METHOD: Comparisons were made between responses to the DOD four-item screener and a brief structured clinical interview for likely deployment-related TBI history. The interview process was facilitated using responses to the Warrior Administered Retrospective Casualty Assessment Tool (WARCAT). RESULTS: The sensitivity and specificity of the DOD screening tool (positive response to all four items) in comparison to the clinician-confirmed diagnosis was 60% and 96%, respectively. The sensitivity increased to 80%, with a slight decrease in specificity to 93%, for positive TBI screening when affirmative responses to questions 1 and 2 only were included. CONCLUSIONS: Affirmative responses to questions 1 and 2 of the DOD TBI screening tool demonstrated higher sensitivity for clinician-diagnosed deployment-related TBI. These two items perform better than positive responses to all four questions; the criteria presently being used for documentation and referral of a deployment-related TBI. These findings support further exploration of TBI screening and assessment procedures.
