RESUMO
OBJECTIVE: To describe associations between a history of traumatic brain injury (TBI) and the severity of tinnitus-related functional impairment among a national, stratified random sample of veterans diagnosed with tinnitus by the Department of Veterans Affairs (VA) healthcare system. SETTING: A multimodal (mailed and internet) survey administered in 2018. Participants: VA healthcare-using veterans diagnosed with tinnitus; veterans with comorbid TBI diagnosis were oversampled. DESIGN: A population-based survey. MAIN MEASURES: TBI history was assessed using International Classification of Diseases (ICD) diagnosis codes in veterans' VA electronic health records. The severity of participants' overall tinnitus-related functional impairment was measured using the Tinnitus Functional Index. Population prevalence and 95% confidence intervals (CIs) were estimated using inverse probability weights accounting for sample stratification and survey nonresponse. Veterans' relative risk ratios of very severe or moderate/severe tinnitus-related functional impairment, versus none/mild impairment, were estimated by TBI history using bivariable and multivariable multinomial logistic regression. RESULTS: The population prevalence of TBI was 5.6% (95% CI: 4.8-6.4) among veterans diagnosed with tinnitus. Veterans with a TBI diagnosis, compared with those without a TBI diagnosis, had 3.6 times greater likelihood of rating their tinnitus-related impairment as very severe (95% CI: 2.1-6.3), and 1.5 times greater likelihood of rating their impairment as moderate/severe (95% CI: 1.0-2.4), versus none/mild. CONCLUSIONS: These findings suggest an important role of TBI in the severity of tinnitus-related functional impairment among veterans. This knowledge can help inform the integration of tinnitus management services into the care received by veterans with TBI.

OBJECTIVE: Post-9/11-era veterans with traumatic brain injury (TBI) have greater health-related complexity than veterans overall, and may require coordinated care from TBI specialists such as those within the Department of Veterans Affairs (VA) healthcare system. With passage of the Choice and MISSION Acts, more veterans are using VA-purchased care delivered by community providers who may lack TBI training. We explored prevalence and correlates of VA-purchased care use among post-9/11 veterans with TBI. SETTING: Nationwide VA-purchased care from 2016 through 2019. PARTICIPANTS: Post-9/11-era veterans with clinician-confirmed TBI based on VA's Comprehensive TBI Evaluation (N = 65 144). DESIGN: This was a retrospective, observational study. MAIN MEASURES: Proportions of veterans who used VA-purchased care and both VA-purchased and VA-delivered outpatient care, overall and by study year. We employed multivariable logistic regression to assess associations between veterans' sociodemographic, military history, and clinical characteristics and their likelihood of using VA-purchased care from 2016 through 2019. RESULTS: Overall, 51% of veterans with TBI used VA-purchased care during the study period. Nearly all who used VA-purchased care (99%) also used VA-delivered outpatient care. Veterans' sociodemographic, military, and clinical characteristics were associated with their likelihood of using VA-purchased care. Notably, in adjusted analyses, veterans with moderate/severe TBI (vs mild), those with higher health risk scores, and those diagnosed with posttraumatic stress disorder, depression, anxiety, substance use disorders, or pain-related conditions had increased odds of using VA-purchased care. Additionally, those flagged as high risk for suicide also had higher odds of VA-purchased care use. CONCLUSIONS: Veterans with TBI with greater health-related complexity were more likely to use VA-purchased care than their less complex counterparts. The risks of potential care fragmentation across providers versus the benefits of increased access to care are unknown. Research is needed to examine health and functional outcomes among these veterans.

OBJECTIVE: To (1) characterize lifetime mild traumatic brain injury (TBI) exposures among male and female US military service members and Veterans (SMVs) and (2) evaluate sex-related differences in mild TBI exposures. SETTING: Clinical research laboratory. PARTICIPANTS: Participants were enrolled in the ongoing Long-term Impact of Military-relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium (LIMBIC-CENC) Prospective Longitudinal Study. DESIGN: Cross-sectional. MAIN MEASURES: Lifetime history of mild TBI was measured via structured interview. All mild TBI characteristics were collected as part of this interview, including total lifetime number; environment (deployment vs. non-deployment); timing of injury (relative to military service and age); and mechanism of injury (blast-related vs. non-blast). RESULTS: Most participants (n = 2323; 87.5% male; 79.6% Veteran) reported ≥1 lifetime mild TBI (n = 1912; 82%), among whom, many reported ≥2 lifetime mild TBIs. Female SMVs reported fewer total lifetime mild TBIs than male participants (P < 0.001), including fewer deployment-related (P < 0.001) and non-deployment (P < 0.001) mild TBIs. There were significant sex differences for total number of mild TBIs sustained before (P = 0.005) and during (P < 0.001) military service but not after separation from military service (P = 0.99). Among participants with a lifetime history of mild TBI, female SMVs were less likely to report ≥2 mTBIs (P = 0.003); however, male SMVs were more likely to report a mild TBI during military service (P = 0.03), including combat-related mild TBI (P < 0.001) and mild TBI involving blast (P < 0.001). CONCLUSIONS: These findings inform clinical and research efforts related to mild TBI in US military SMVs. It may not be sufficient to simply measure the total number of mild TBIs when seeking to compare clinical outcomes related to mild TBI between sexes; rather, it is important to measure and account for the timing, environment, and mechanisms associated with mild TBIs sustained by female and male SMVs.
RESUMO
Objective: The current study sought to describe a nationally representative sample of Veterans diagnosed with co-occurring PTSD and substance use disorder (SUD) who initiated and completed evidence-based psychotherapy (EBP) for PTSD, and explored whether completion rates differed by SUD subtype. Methods: Using electronic health record data from the Veterans Health Administration (VHA) Corporate Data Warehouse, Veterans with a dual diagnosis of PTSD and SUD who initiated either Cognitive Processing Therapy (CPT) or Prolonged Exposure (PE) between January 01, 2019 and July 16, 2019 were identified (N = 2,996). Logistic analyses were employed to determine whether there were differences in EBP completion rates among Veterans with an alcohol use disorder (AUD; n = 1,383) versus all other SUDs (n = 1,613). Results: On average, Veterans were 45 years old, and identified as male, White, and non-Hispanic. Logistic regression analyses revealed there was not a significant difference between Veterans with AUD only and other SUDs in the probability of completing EBP treatment, OR = 1.02, 95% CI =0.87, 1.17, p = 0.79. Conclusions: No differences in EBP completion rates were observed between SUD subtypes, indicating that EBPs for PTSD are tolerated well for individuals with various types of SUDs and may be offered as treatment options.

OBJECTIVE: To examine the relationship between neuropsychological functioning and performance-based functional capacity in veterans with a history of mild traumatic brain injury (mTBI), as well as the moderating effects of age and psychiatric symptoms on this relationship. SETTING: Three Veterans Affairs medical centers. PARTICIPANTS: One hundred nineteen Iraq/Afghanistan veterans with a history of mTBI and self-reported cognitive difficulties. DESIGN: Cross-sectional, secondary data analysis of baseline measures in a randomized controlled trial. MAIN MEASURES: The main outcome measure, functional capacity, was assessed using the objective and performance-based University of California San Diego Performance-based Skills Assessment-Brief. A global deficit score (GDS) was created as a composite score for performance on a battery of neuropsychological measures assessing domains of attention, processing speed, executive functioning, and verbal memory performance. Posttraumatic stress disorder (PTSD) symptom severity was assessed using the PTSD Checklist-Military Version, and depressive symptom severity was assessed using the Beck Depression Inventory, Second Edition. RESULTS: Bivariate analyses indicated that worse neuropsychological performance (ie, higher GDS) and greater PTSD symptom severity were associated with worse communication abilities and worse overall functional capacity. Multiple linear regressions demonstrated that GDS and PTSD symptom severity explained 9% of the variance in communication and 10% of the variance in overall functional capacity; however, GDS emerged as the only significant predictor in both regressions. Age, PTSD, and depressive symptom severity did not moderate the relationship between GDS and overall functional capacity. Performance in the verbal learning and memory domain emerged as the strongest neuropsychological predictor of communication and overall functional capacity. CONCLUSIONS: Worse neuropsychological functioning was moderately associated with worse performance-based functional capacity, even when accounting for PTSD symptom severity. Verbal learning and memory was the primary neuropsychological domain driving the relationship with functional capacity; improvement in verbal learning and memory may translate into improved functional capacity.

OBJECTIVE: To describe associations of demographic, military, and health comorbidity variables between mild traumatic brain injury (mTBI) history and posttraumatic stress disorder (PTSD) status in a sample of Former and current military personnel. SETTING: Participants recruited and tested at seven VA sites and one military training facility in the LIMBIC-CENC prospective longitudinal study (PLS), which examines the long-term mental health, neurologic, and cognitive outcomes among previously combat-deployed U.S. Service Members and Veterans (SM/Vs). PARTICIPANTS: A total of 1,540 SM/Vs with a history of combat exposure. Data were collected between 1/1/2015 through 3/31/2019. DESIGN: Cross-sectional analysis using data collected at enrollment into the longitudinal study cohort examining demographic, military, and health comorbidity variables across PTSD and mTBI subgroups. MAIN MEASURES: PTSD Checklist for DSM-5 (PCL-5), mTBI diagnostic status, Patient Health Questionnaire 9-item (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), AUDIT-C, and other self-reported demographic, military, and health comorbidity variables. RESULTS: Ten years following an index date of mTBI exposure or mid-point of military deployment, combat-exposed SM/Vs with both mTBI history and PTSD had the highest rates of depression symptoms, pain, and sleep apnea risk relative to SM/Vs without both of these conditions. SM/Vs with PTSD, irrespective of mTBI history, had high rates of obesity, sleep problems, and pain. CONCLUSION: The long-term symptom reporting and health comorbidities among SM/Vs with mTBI history and PTSD suggest that ongoing monitoring and intervention is critical for addressing symptoms and improving quality of life.

OBJECTIVE: Many post-9/11 Veterans have received Department of Veterans Affairs (VA) healthcare for traumatic brain injury (TBI). Pain conditions are prevalent among these patients and are often managed with opioid analgesics. Opioids may impose unique risks to Veterans with a history of TBI, especially when combined with other psychotropic medications. We examined receipt of opioid and sedative-hypnotic prescriptions among post-9/11 Veterans with TBI who received VA care nationally between 2012 and 2020. SETTING: Nationwide VA outpatient care. PARTICIPANTS: Veterans with, versus without, clinician-confirmed TBI based on the VA's Comprehensive TBI Evaluation (CTBIE) were followed up for subsequent years in which they received VA care. DESIGN: A historical cohort study. MAIN MEASURES: Proportions of Veterans who received opioid, benzodiazepine, and nonbenzodiazepine sedative-hypnotic prescriptions were compared by CTBIE outcome (TBI yes/no) and by year; overlaps between medication classes, long-term opioid therapy, and high-dose opioid therapy were also examined. Among those with confirmed TBI, logistic regression was used to examine associations between veteran characteristics and likelihood of these potentially high-risk opioid use outcomes. RESULTS: Among 69 752 Veterans with clinician-confirmed TBI, 26.9% subsequently received opioids. The prevalence receiving opioids each year increased from 2012 (16.7%) to 2014 (17.7%), and then decreased each of the following years through 2020 (5.8%). Among Veterans with TBI who received opioids, large proportions also received benzodiazepine (30.1%) and nonbenzodiazepine (36.0%) sedative-hypnotic prescriptions; these proportions also decreased in recent years. In both bivariable and multivariable regression models, Veterans' demographic, TBI, and clinical characteristics were associated with likelihood of potentially high-risk opioid use. CONCLUSIONS: VA opioid prescribing to Veterans with TBI has decreased in recent years but remains an important source of risk, particularly when considering coprescriptions of sedative-hypnotic medication. Understanding patterns of psychotropic prescription use among Veterans with TBI can highlight important healthcare and rehabilitation needs in this large patient cohort.

OBJECTIVE: To describe rates of mild traumatic brain injury (mTBI) with and without concurrent posttraumatic stress disorder a sample of former and current military personnel, and to compare the factor structure of the Neurobehavioral Symptom Inventory (NSI) based on whether participants sustained mTBI with and without a positive posttraumatic stress disorder (PTSD) screen. SETTING: Participants recruited and tested at 7 Veterans Affairs (VA) sites and 1 military training facility as part of a national, longitudinal study of mental health, physical, and cognitive outcomes among veterans and service members. Participants: Total of 1540 former and current military personnel with a history of combat exposure. DESIGN: Cross-sectional analysis of observational data, including confirmatory factor analysis. Main Measures: NSI and PTSD Checklist for DSM-5 (PCL-5). RESULTS: Most participants (81.5%) had a history of mTBI and almost half of these screened positive for PTSD (40.5%); only 23.9% of participants without a history of mTBI screened positive for PTSD. Participants with a history of mTBI reported higher elevations of NSI and PCL-5 symptoms compared with those without a history of mTBI. Confirmatory factor analyses of the NSI demonstrated good model fit using a 4-factor structure (somatosensory, affective, cognitive, and vestibular symptoms) among groups of participants both with and without a history of mTBI. CONCLUSION: Symptoms of mTBI and PTSD are strongly associated with each other among veterans and service members with a history of combat exposure. The 4-factor NSI structure is supported among participants with and without a history of mTBI. These findings suggest the potential benefit of a holistic approach to evaluation and treatment of veterans and service members with concurrent and elevated postconcussive and posttraumatic stress symptoms.

OBJECTIVE: The purpose of this study was to determine modifiable predictors of intervention adherence in a study of group-based Compensatory Cognitive Training (CCT) for Iraq/Afghanistan War veterans with a history of mild traumatic brain injury (mTBI). METHODS: One hundred twenty-three veterans enrolled in a randomized controlled trial of a 10-week CCT intervention (54 assigned to CCT) and were evaluated at baseline, 5 weeks, 10 weeks, and 15 weeks. CCT adherence was determined by the number of CCT sessions attended, with more sessions indicative of greater adherence. Baseline demographic and clinical characteristics, and subjective and objective neuropsychological performance, were examined in relation to CCT session attendance. RESULTS: Older age and worse attention performance at baseline were associated with higher CCT attendance rates. CONCLUSIONS: This study generates preliminary evidence for potential modifiable neuropsychological factors that may improve engagement in CCT interventions.

Background: Cannabis use disorder (CUD) is a growing concern, and evidence-based data are needed to inform treatment options. Purpose: To review the benefits and risks of pharmacotherapies for the treatment of CUD. Data Sources: MEDLINE, PsycINFO, Cochrane Database of Systematic Reviews, and clinical trial registries from inception through September 2019. Study Selection: Pharmacotherapy trials of adults or adolescents with CUD that targeted cannabis abstinence or reduction, treatment retention, withdrawal symptoms, and other outcomes. Data Extraction: Data were abstracted by 1 investigator and confirmed by a second. Study quality was dually assessed, and strength of evidence (SOE) was determined by consensus according to standard criteria. Data Synthesis: Across 26 trials, the evidence was largely insufficient. Low-strength evidence was found that selective serotonin reuptake inhibitors (SSRIs) do not reduce cannabis use or improve treatment retention. Low- to moderate-strength evidence was found that buspirone does not improve outcomes and that cannabinoids do not increase abstinence rates (moderate SOE), reduce cannabis use (low SOE), or increase treatment retention (low SOE). Across all drug studies, no consistent evidence of increased harm was found. Limitations: Few methodologically rigorous trials have been done. Existing trials are hampered by small sample sizes, high attrition rates, and heterogeneity of concurrent interventions and outcomes assessment. Conclusion: Although data on pharmacologic interventions for CUD are scarce, evidence exists that several drug classes, including cannabinoids and SSRIs, are ineffective. Because of increasing access to and use of cannabis in the general population, along with a high prevalence of CUD among current cannabis users, an urgent need exists for more research to identify effective pharmacologic treatments.

Given the extensive research on posttraumatic stress disorder (PTSD) treatment, a single, updatable repository of data from PTSD treatment studies would be useful for clinical, research, and policy stakeholders. To meet this need, we established a preliminary dataset of abstracted PTSD trial data, which serve as the basis for the PTSD Trials Standardized Data Repository (PTSD-Repository), maintained by the National Center for PTSD (NCPTSD). We followed systematic review methods to identify published randomized controlled trials (RCTs) of PTSD interventions. We consulted with a panel of experts to determine a priori inclusion criteria, ensure that we captured all relevant studies, and identify variables for abstraction. We searched multiple databases for materials published from 1980 to 2018 and reviewed reference lists of relevant systematic reviews and clinical practice guidelines. In total, 318 RCTs of PTSD interventions that enrolled almost 25,000 participants were included. We abstracted 337 variables across all studies, including study, participant, and intervention characteristics as well as results. In the present paper, we describe our methods and define data elements included in the data tables. We explain coding challenges, identify inconsistencies in reporting across study types, and discuss ways stakeholders can use PTSD-Repository data to enhance research, education, and policy. The abstracted data are currently publicly available on the NCPTSD website and can be used for future systematic reviews and identifying research gaps and as an information resource for clinicians, patients, and family members.

OBJECTIVES: To quantify the need for, and interest in, supported employment (SE) among recent military veterans with traumatic brain injury (TBI); and to examine characteristics associated with veterans' interest in SE. DESIGN: Stratified random sample of Iraq and Afghanistan War veterans confirmed to have TBI through the Veterans Health Administration (VHA) screening and evaluation system. SETTING: Community-based via mailed survey. PARTICIPANTS: We recruited 1800 veterans with clinician-confirmed TBI (mild TBI: n=1080; moderate/severe TBI: n=720) through multiple mailings. Among 1451 surveys that were not returned undeliverable, N=616 (42%) responded. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Veterans rated their interest in SE after reading a script describing the program. Additional measures assessed mental health and pain-related comorbidities, employment, financial/housing difficulties, demographics, and military service characteristics. Estimates were weighted to represent the population of veterans with VHA clinician-confirmed TBI. RESULTS: Unemployment was reported by 45% (95% confidence interval [CI], 43-47) of veterans with TBI. Although 42% (95% CI, 40-44) reported they would be interested in using SE if it were offered to them, only 12% had heard of SE (95% CI, 11-14) and <1% had used it. TBI severity and comorbidities were not associated with veterans' interest in SE. However, those who were unemployed, looking for work, experiencing financial strain, or at risk for homelessness were more likely to be interested in SE. CONCLUSIONS: Our research highlights an important gap between veterans' vocational needs and interests and their use of SE. Systematically identifying and referring those with employment and financial/housing difficulties may help close this gap.

BACKGROUND: Cannabis is available from medical dispensaries for treating posttraumatic stress disorder (PTSD) in many states of the union, yet its efficacy in treating PTSD symptoms remains uncertain. PURPOSE: To identify ongoing studies and review existing evidence regarding the benefits and harms of plant-based cannabis preparations in treating PTSD in adults. DATA SOURCES: MEDLINE, the Cochrane Library, and other sources from database inception to March 2017. STUDY SELECTION: English-language systematic reviews, trials, and observational studies with a control group that reported PTSD symptoms and adverse effects of plant-based cannabis use in adults with PTSD. DATA EXTRACTION: Study data extracted by 1 investigator was checked by a second reviewer; 2 reviewers independently assessed study quality, and the investigator group graded the overall strength of evidence by using standard criteria. DATA SYNTHESIS: Two systematic reviews, 3 observational studies, and no randomized trials were found. The systematic reviews reported insufficient evidence to draw conclusions about benefits and harms. The observational studies found that compared with nonuse, cannabis did not reduce PTSD symptoms. Studies had medium and high risk of bias, and overall evidence was judged insufficient. Two randomized trials and 6 other studies examining outcomes of cannabis use in patients with PTSD are ongoing and are expected to be completed within 3 years. LIMITATION: Very scant evidence with medium to high risk of bias. CONCLUSION: Evidence is insufficient to draw conclusions about the benefits and harms of plant-based cannabis preparations in patients with PTSD, but several ongoing studies may soon provide important results.

BACKGROUND: Cannabis is increasingly available for the treatment of chronic pain, yet its efficacy remains uncertain. PURPOSE: To review the benefits of plant-based cannabis preparations for treating chronic pain in adults and the harms of cannabis use in chronic pain and general adult populations. DATA SOURCES: MEDLINE, Cochrane Database of Systematic Reviews, and several other sources from database inception to March 2017. STUDY SELECTION: Intervention trials and observational studies, published in English, involving adults using plant-based cannabis preparations that reported pain, quality of life, or adverse effect outcomes. DATA EXTRACTION: Two investigators independently abstracted study characteristics and assessed study quality, and the investigator group graded the overall strength of evidence using standard criteria. DATA SYNTHESIS: From 27 chronic pain trials, there is low-strength evidence that cannabis alleviates neuropathic pain but insufficient evidence in other pain populations. According to 11 systematic reviews and 32 primary studies, harms in general population studies include increased risk for motor vehicle accidents, psychotic symptoms, and short-term cognitive impairment. Although adverse pulmonary effects were not seen in younger populations, evidence on most other long-term physical harms, in heavy or long-term cannabis users, or in older populations is insufficient. LIMITATION: Few methodologically rigorous trials; the cannabis formulations studied may not reflect commercially available products; and limited applicability to older, chronically ill populations and patients who use cannabis heavily. CONCLUSION: Limited evidence suggests that cannabis may alleviate neuropathic pain in some patients, but insufficient evidence exists for other types of chronic pain. Among general populations, limited evidence suggests that cannabis is associated with an increased risk for adverse mental health effects. PRIMARY FUNDING SOURCE: U.S. Department of Veterans Affairs.

A history of mild traumatic brain injury (mTBI) is common among military members who served in Operations Enduring Freedom, Iraqi Freedom, and New Dawn (OEF/OIF/OND). We completed a systematic review to describe the cognitive, mental health, physical health, functional, social, and cost consequences of mTBI in Veteran and military personnel. Of 2668 reviewed abstracts, the 31 included studies provided very low strength evidence for the questions of interest. Cognitive, physical, and mental health symptoms were commonly reported by Veterans/military members with a history of mTBI. On average, these symptoms were not significantly more common in those with a history of mTBI than in those without, although a lack of significant mean differences does not preclude the possibility that some individuals could experience substantial effects related to mTBI history. Evidence of potential risk or protective factors moderating mTBI outcomes was unclear. Although the overall strength of evidence is very low due to methodological limitations of included studies, our findings are consistent with civilian studies. Appropriate re-integration services are needed to address common comorbid conditions, such as treatment for post-traumatic stress disorder, substance use disorders, headaches, and other difficulties that Veterans and members of the military may experience after deployment regardless of mTBI history.

RESUMO
OBJECTIVE: This proof-of-concept study was conducted to establish the feasibility of compiling Federal Interagency Traumatic Brain Injury Research (FITBIR) data pertaining to depression and suicide risk, with the secondary goal of improving understanding regarding these outcomes. FITBIR is a national repository of participant-level traumatic brain injury (TBI) data designed to address methodological limitations (e.g., small sample size, heterogeneity of injuries). METHOD: FITBIR studies with TBI severity and measures related to depression and suicidal ideation were identified. Data were harmonized across relevant studies and grouped to identify "probable depression" and suicidal ideation, resulting in a large, combined sample. Rates of probable depression and suicidal ideation were described across the available studies, considering the influence of demographic and/or injury-related factors on outcomes. RESULTS: Cross-sectional studies meeting criteria included four studies with depression outcomes and two with suicidal ideation outcomes. Two studies reported data appropriate for comparative analyses on depression. Combined results suggested that approximately 71% of participants were categorized as having probable depression. Participants with a history of mild TBI had 2.54 greater odds of probable depression (95% confidence interval [1.93, 3.34]) than those without a history of TBI. CONCLUSIONS: Methods, harmonization code, and meta-databases related to TBI, probable depression, and suicidal ideation are now publicly available on the FITBIR website. Even with limited data, harmonization of FITBIR studies can serve as the basis for ongoing TBI and mental health research. Analyses will be more robust in the future as more studies with relevant outcome data are added to the FITBIR database. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Sleep-wake disturbances frequently present in Veterans with mild traumatic brain injury (mTBI). These TBI-related sleep impairments confer significant burden and commonly exacerbate other functional impairments. Therapies to improve sleep following mTBI are limited and studies in Veterans are even more scarce. In our previous pilot work, morning bright light therapy (MBLT) was found to be a feasible behavioral sleep intervention in Veterans with a history of mTBI; however, this was single-arm, open-label, and non-randomized, and therefore was not intended to establish efficacy. The present study, LION (light vs ion therapy) extends this preliminary work as a fully powered, sham-controlled, participant-masked randomized controlled trial (NCT03968874), implemented as fully remote within the VA (target n=120 complete). Randomization at 2:1 allocation ratio to: 1) active: MBLT (n=80), and 2) sham: deactivated negative ion generator (n=40); each with identical engagement parameters (60-min duration; within 2-hrs of waking; daily over 28-day duration). Participant masking via deception balanced expectancy assumptions across arms. Outcome measures were assessed following a 14-day baseline (pre-intervention), following 28-days of device engagement (post-intervention), and 28-days after the post-intervention assessment (follow-up). Primary outcomes were sleep measures, including continuous wrist-based actigraphy, self-report, and daily sleep dairy entries. Secondary/exploratory outcomes included cognition, mood, quality of life, circadian rhythm via dim light melatonin onset, and biofluid-based biomarkers. Participant drop out occurred in <10% of those enrolled, incomplete/missing data was present in <15% of key outcome variables, and overall fidelity adherence to the intervention was >85%, collectively establishing feasibility and acceptability for MBLT in Veterans with mTBI.
RESUMO
This study sought to examine the relationship between coping strategies and prosocial and deviant peer associations for urban, African American adolescents. In addition, the study analyzed the mediating role of ethnic identity for coping strategies and peer associations. Results of the African American models were then compared with models for European American adolescents. Results indicated that African American and European American adolescents who reported using distraction coping strategies were more likely to associate with prosocial peers, and those who reported using self-destruction strategies were less likely to associate with prosocial peers. Adolescents who reported using distraction coping strategies were less likely to associate with deviant peers, and adolescents who reported using self-destruction strategies were more likely to associate with deviant peers. Ethnic identity mediated the relationship between coping and prosocial peer association for African American adolescents. Limitations of the study and future research directions are also presented.
RESUMO
Mind-body interventions (MBIs) include mindfulness-based interventions (MiBIs), meditation- and mantra-based interventions (MMIs), and movement-based interventions (MoBIs). These approaches have demonstrated preliminary efficacy in improving posttraumatic stress disorder (PTSD) symptoms. However, previous systematic reviews and meta-analyses have noted that this area of research is limited by inadequate comparator conditions, heterogeneity of measurement, and absence of objective outcome measures. For these reasons, an updated review of the highest-quality evidence available is warranted. We used the Agency for Healthcare Research and Quality (AHRQ)-funded evidence tables for the PTSD-Repository to identify relevant studies and assess the risk of bias as follows: The search was conducted between June 2018 and June 2022, and databases included PTSDpubs (formerly PILOTS), Ovid® MEDLINE®, Cochrane CENTRAL, Embase®, the Cumulative Index to Nursing and Allied Health Literature (CINAHL®), SCOPUS, and PsycINFO®. Twenty-six randomized controlled trials met our inclusion criteria. After identifying studies and retrieving risk of bias information from the PTSD-Repository evidence tables, we extracted additional data and synthesized the evidence. The strength of evidence was rated as low for MiBIs and MMIs, largely due to contradicting results, inconsistent use of active versus passive comparators, and high risk of bias. The strength of evidence for MoBIs was rated as moderate due to individual studies consistently favoring the intervention and a relatively large number of studies and participants. Of the 26 included studies, only two included objective outcome measures. Implications for future MBI research and clinical applications for treating PTSD are discussed.
