Characterizing Health Literacy and Its Correlates Among Individuals With Traumatic Brain Injury (TBI): A TBI Model Systems Study.

OBJECTIVE: To characterize health literacy among individuals with traumatic brain injury (TBI) at least a year postinjury and to explore its relationship to sociodemographic variables, injury severity, and cognition. SETTING: Community following discharge from inpatient rehabilitation. PARTICIPANTS: In total, 205 individuals with complicated mild to severe TBI who completed follow-up as part of a national longitudinal study of TBI and completed a web-based health literacy measure. DESIGN: Multicenter, cross-sectional, observational study. MAIN MEASURES: Health Literacy Assessment Using Talking Touchscreen Technology. RESULTS: Thirty-one percent of the sample demonstrated marginal/inadequate health literacy; 69% demonstrated adequate health literacy. A higher proportion of non-Hispanic White adults had adequate health literacy than non-Hispanic Black and Hispanic adults. Individuals with greater than a high school education were more likely to have adequate health literacy than those with a high school education or less. Better executive functioning performance was related to adequate health literacy. Better episodic memory performance was related to adequate health literacy, but only for those with complicated mild to moderate injury. CONCLUSIONS: A substantial proportion of individuals with TBI have marginal/inadequate health literacy, which may impact their understanding, appreciation, and use of health-related information and recommendations. While low health literacy may be preexisting, directly related to TBI, or a combination of both, it should be screened and considered by professionals when communicating with persons with TBI. Healthcare providers should tailor their communication approaches and presentation of health information, particularly for those with low health literacy.

Neurobehavioral Symptoms in Spanish-Speaking Individuals With Subconcussive Injuries.

OBJECTIVE: To examine whether exposure to high-risk events causing injury to the head or neck has an effect on neurobehavioral symptoms in the absence of an alteration of consciousness in Spanish-speakers. SETTING: Web-based survey. PARTICIPANTS: Seven hundred forty-eight individuals from Spain and Latin America, aged 18 to 65 years, with 10 years or more of education. Thirty-nine participants failed quality checks and were excluded. Seven hundred nine participants were included in the analyses. DESIGN: Cross-sectional study. Subconcussive exposure was defined as endorsing exposure to one or more high-risk scenarios in the absence of any alteration of consciousness. Three injury groups were derived: No Head Injury, Subconcussive Exposure, and traumatic brain injury (TBI). The Subconcussive Exposure group was further divided into Single and Multiple Exposures. Two analyses were conducted: the effect of lifetime exposure to injury (No Head Injury, Subconcussive Exposure, TBI) on neurobehavioral symptoms; the effect of Subconcussive Exposure Frequency (No Head Injury, Single Exposure, Multiple Exposures) on neurobehavioral symptoms. MAIN MEASURES: Spanish Ohio State University Traumatic Brain Injury Identification Method Self-Administered-Brief (OSU TBI-ID SAB); Neurobehavioral Symptom Inventory (NSI). RESULTS: There was a significant effect for Injury group on the NSI partial eta-squared (ηp2 = 0.053) and a significant effect of Exposure Frequency group on the NSI (ηp2 = 0.40). Individuals with subconcussive exposures reported significantly more neurobehavioral symptoms than those with no history of head injury and significantly less symptoms than those with TBI. Individuals with multiple subconcussive exposures reported significantly more neurobehavioral symptoms than those with single and no exposure. CONCLUSION: This research expands the utility of the OSU-TBI-ID SAB as a lifetime TBI history assessment tool to one capable of evaluating subconcussive exposure dosing effects in Spanish-speakers. Such an index may facilitate establishment of subconcussive exposure prevalence rates worldwide, leading to improved understanding of the chronic effects of high-risk exposures.

The Relationship of Health Literacy to Health Outcomes Among Individuals With Traumatic Brain Injury: A Traumatic Brain Injury Model Systems Study.

OBJECTIVE: To examine the associations between health literacy and health outcomes among individuals with traumatic brain injury (TBI) at least a year post-injury. SETTING: Community following discharge from inpatient rehabilitation. PARTICIPANTS: A total of 205 individuals with complicated mild to severe TBI who completed a TBI Model Systems National Database follow-up interview and a web-based health literacy measure. DESIGN: A multicenter, cross-sectional, observational study. MAIN MEASURES: The Health Literacy Assessment Using Talking Touchscreen Technology (Health LiTT), number of comorbid conditions (Medical and Mental Health Comorbidities Interview [MMHCI]), perceived physical and mental health (PROMIS Global Physical and Mental Health subscales), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7). RESULTS: After controlling for sociodemographic, injury, cognition, and time post-injury, adequate health literacy was associated with higher odds of greater perceived physical health compared with participants with marginal/inadequate health literacy (odds ratio = 4.10; CI = 1.52-11.70]. Participants with inadequate/marginal health literacy had 3.50 times greater odds of depression (PHQ-9 ≥ 10) compared with those with adequate health literacy. Participants 45 years and older reported a greater number of MMHCI physical health conditions, but fewer MMHCI mental health conditions and GAD-7 anxiety symptoms compared with those who were younger. Non-Hispanic White participants and those with mild/moderate TBI were more likely to report a greater number of MMHCI mental health conditions compared with non-Hispanic Black participants or those with severe TBI. Greater time post-injury was associated with greater number of chronic physical and mental health conditions, and less odds of good-to-excellent perceived global mental health. CONCLUSIONS: Inadequate health literacy is associated with worse perceived physical health and greater depressive symptoms among adults with TBI. Greater efforts are needed to explore the mechanisms by which health literacy influences chronic disease management and mental health after TBI to improve postinjury health status and outcomes, particularly among those with limited health literacy skills.

Assessing menopause symptoms in women with traumatic brain injury: the development and initial testing of a new scale.

With greater survival rates after catastrophic injury, more women with traumatic brain injury (TBI) are living longer than ever. However, knowledge about this transition in these women is largely unexamined and there are no scales that have been developed to assess the experience of symptoms. To address this gap, we developed and tested a new scale of menopause symptoms in midlife women with TBI. We selected candidate items from two existing measures based on feedback from focus group discussions with seven women with TBI. Twenty candidate items were tested in cognitive interviews with six women with TBI/1 non-TBI. Then, these were field tested with 221 participants (TBI, n = 68; non-TBI, n = 153) recruited from registries. Rasch analysis and convergent validity testing were used to evaluate the new scale. Results of the Rasch analysis indicate that overall, the scale fits well the Rasch model with evidence for unidimensionality. Differential item functioning indicated that the scale performed equally well for women with and without TBI and distinguished pre- and post-menopausal states. Convergent validity was found in the expected directions. These findings support further development of the new scale to understand the experience of menopause symptoms among women with TBI.

Trajectories of life satisfaction in Hispanic individuals over the 10 years after traumatic brain injury: A model systems study.

PURPOSE: To identify life satisfaction trajectories at 1-10 years post-traumatic brain injury (TBI) and examine which demographic and injury characteristics at the time of injury are associated with those trajectories. METHODS: Participants included 1,051 Hispanic individuals from the multi-site, longitudinal TBI Model Systems (TBIMS) database. Individuals were enrolled after sustaining a TBI and while undergoing inpatient rehabilitation at a TBIMS site; they were included if they completed the Satisfaction with Life Scale during one or more follow-up data collections at 1, 2, 5, or 10 years after TBI. RESULTS: A linear (straight-line) movement of life satisfaction trajectories was the best fit to the data. Across the overall sample, life satisfaction increased over time, with higher trajectories for Hispanic individuals who had been partnered at baseline, born outside the US and experienced a nonviolent injury cause. There were no significant interactions between time and any of these main effect predictors, suggesting no differential change over time in life satisfaction trajectories as a function of these characteristics. CONCLUSIONS: Results revealed increases in life satisfaction over time among Hispanic individuals with TBI and shed light on critical risks and protective factors that may inform targeted rehabilitation services with this underserved group.

Traumatic brain injury as a chronic disease: insights from the United States Traumatic Brain Injury Model Systems Research Program.

Traumatic brain injury (TBI) is a global health priority, associated with substantial burden. Historically conceptualised as an injury event with finite recovery, TBI is now recognised as a chronic condition that can affect multiple domains of health and function, some of which might deteriorate over time. Many people who have had a TBI remain moderately to severely disabled at 5 years, are rehospitalised up to 10 years post-injury, and have a reduced lifespan relative to the general population. Understanding TBI as a chronic disease process can be highly informative for optimising care, which has traditionally focused on acute care. Chronic brain injury care models must be informed by a holistic understanding of long-term outcomes and the factors that can affect how care needs evolve over time. The United States Traumatic Brain Injury Model Systems of Care follows up individuals with moderate-to-severe TBI for over 30 years, allowing characterisation of the chronic (2-30 years or more post injury) functional, cognitive, behavioural, and social sequelae experienced by individuals who have had a moderate-to-severe TBI and the implications for their health and quality of life. Older age, social determinants of health, and lower acute functional status are associated with post-recovery deterioration, while younger age and greater functional independence are associated with risky health behaviours, including substance misuse and re-injury. Systematically collected data on long-term outcomes across multiple domains of health and function are needed worldwide to inform the development of models for chronic disease management, including the proactive surveillance of commonly experienced health and functional challenges.

Translation of Karnofsky Performance Status (KPS) for use in inpatient cancer rehabilitation.

BACKGROUND: Better tools are needed to predict functional decline and oncologic prognosis in inpatient cancer rehabilitation. The Karnofky Performance Status (KPS) is a widely used scale of functional performance in oncology, although the scale differs from current rehabilitation terminology. Use of the KPS in inpatient rehabilitation may support a shared method of communication between cancer rehabilitation providers and the primary oncology teams. OBJECTIVE: To establish interrater reliability for translation of the KPS for use in inpatient cancer rehabilitation. DESIGN: Retrospective interrater reliability review. SETTING: A large inpatient rehabilitation hospital system. PARTICIPANTS: Fifty randomized charts were chosen for review from a larger database of all patients admitted to an inpatient cancer rehabilitation program in 2020. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: The KPS scale was translated into common inpatient rehabilitation grading consistent with the Continuity and Assessment Record and Evaluation (CARE) Item Set to support its use in this specialty area. Additionally, a list of best practice guidelines and scoring instructions were created to assist raters in determining appropriate levels within the scale. Members of the inpatient cancer rehabilitation team scored all patients within the larger database (n = 424) throughout 2020. A blinded rater completed retrospective chart reviews to score the 50-chart sample. A two-way random effects model was used to calculate an intraclass correlation coefficient (ICC) for the KPS scores at each of three time points (premorbid, admission, and discharge). RESULTS: The KPS interpretation for rehabilitation proved to be statistically reliable for the 50-chart sample. The premorbid KPS interrater reliability was acceptable (ICC = 0.67; 95% confidence interval [CI]: 0.40-0.82), admission KPS reliability was good (ICC = 0.88, 95% CI: 0.78-0.93), and discharge reliability was excellent (ICC = 0.96; 95% CI: 0.91-0.98). CONCLUSION: The KPS translation at three time points (premorbid, admission, and discharge) during the inpatient rehabilitation continuum has acceptable interrater reliability.

The Association Between Payer Source and Traumatic Brain Injury Rehabilitation Outcomes: A TBI Model Systems Study.

OBJECTIVE: To examine the relationship between payer source for acute rehabilitation, residential median household income (MHI), and outcomes at rehabilitation discharge after traumatic brain injury (TBI). SETTING: Acute inpatient rehabilitation facilities. PARTICIPANTS: In total, 8558 individuals enrolled in the Traumatic Brain Injury Model Systems (TBIMS) National Database who were admitted to inpatient rehabilitation between 2006 and 2019 and were younger than 64 years. DESIGN: Secondary data analysis from a multicenter longitudinal cohort study. MAIN MEASURES: Payer source was divided into 4 categories: uninsured, public insurance, private insurance, and workers' compensation/auto. Relationships between payer source with residential MHI, rehabilitation length of stay (RLOS), and the FIM Instrument at discharge were examined. Covariates included age, injury severity, FIM at admission, and a number of sociodemographic characteristics including minority status, preinjury limitations, education level, and employment status. RESULTS: Individuals with workers' compensation/auto or private insurance had longer RLOS than uninsured individuals or those with public insurance after controlling for demographics and injury characteristics. An adjusted model controlling for demographics and injury characteristics showed a significant main effect of payer source on FIM scores at discharge, with the highest scores noted among those with workers' compensation/auto insurance. The main effect of payer source on FIM at discharge became nonsignificant after RLOS was added to the model as a covariate, suggesting a mediating effect of RLOS. CONCLUSION: Payer source was associated with preinjury residential MHI and predicted RLOS. While prior studies have demonstrated the effect of payer source on long-term outcomes due to lack of inpatient rehabilitation or quality follow-up care, this study demonstrated that individuals with TBI who are uninsured or have public insurance may be at risk for poorer functional status at the point of rehabilitation discharge than those with private insurance, particularly compared with those with workers' compensation/auto insurance. This effect may be largely driven by having a shorter length of stay in acute rehabilitation.

Preliminary construct validity of a memory concerns scale derived from a PROMIS® item bank in a spanish-speaking sample.

This study examined preliminary evidence of construct validity in a stand-alone memory concerns scale constructed from the Patient-Reported Outcomes Measurement Information System (PROMIS®) Cognitive Function item bank. A sample of 396 individuals, ages 18-75 (M = 33.7, SD = 12.7), from Spain and Latin America completed an online survey regarding lifetime exposure to factors associated with neurological compromise. The sample was 69.4% female. Respondents completed 8 items from the PROMIS® Cognitive Function item bank v1.0 dealing with memory concerns (MCS-8) along with the PROMIS® 8-item short form reflecting general cognitive concerns (CCS-8). The MCS-8 had high internal consistency reliability (Cronbach's alpha = 0.90), and represented a factor distinct from general cognitive concerns items on the CCS-8 in confirmatory factor analysis. Analysis of covariance controlling for sex, age, and education, showed that individuals endorsing history of exposure to sources of neurological compromise scored significantly lower T-scores on the MCS-8 than those who did not report any such history, F(1,390) = 6.4, p = 0.012. Older age was significantly associated with greater memory concerns, a relationship with age not observed with the CCS-8. As a stand-alone self-report measure, the MCS-8 appears to measure a construct distinct from general cognitive concerns that may be of interest for further research in clinical populations.

Trajectories of Cognitive and Motor Functional Independence in Hispanic Individuals During the 10 yrs After Traumatic Brain Injury.

OBJECTIVE: This study examined demographic and injury-related predictors of cognitive and motor functional independence in Hispanics with traumatic brain injury at years 1, 2, 5, and 10 after hospital discharge. DESIGN: Hispanic participants ( n = 1360) from the TBI Model Systems Study were included if they had at least one Functional Independence Measure (FIM) Cognitive and Motor score at any time point (years 1, 2, 5, or 10). Hierarchical linear modeling was used to examine baseline predictors of FIM Cognitive and Motor trajectories across this period. RESULTS: FIM Cognitive trajectories showed a quadratic movement (initial increase followed by a plateau or slight decrease), whereas FIM Motor trajectories showed a cubic movement (initial increase, followed by a plateau, then another increase). Higher FIM Cognitive trajectories were predicted by younger age, shorter length of posttraumatic amnesia, higher education, and having experienced a nonviolent mechanism of injury. Higher FIM Motor trajectories were predicted by younger age, shorter posttraumatic amnesia, and a nonviolent mechanism of injury. CONCLUSIONS: The baseline predictors of functional trajectories identified may help create tailored, evidence-based rehabilitation interventions along the continuum of recovery during the first 10 yrs for Hispanics with traumatic brain injury at risk for reduced functional outcomes.

Validation of the Norma Latina neuropsychological assessment battery in individuals with multiple sclerosis in Mexico.

BACKGROUND: Between 50-60% of Multiple Sclerosis (MS) patients have cognitive alterations. There are several batteries to assess cognitive impairments in MS, however, few exist for Latin Americans. The objective of this study is to evaluate the neuropsychological profile of Mexican people with MS (PwMS) and assess the utility of Norma Latina, a new battery for cognitive assessment in Latin America, in differentiating cognitive test performance between PwMS and healthy controls (HCs). METHODS: 100 PwMS and 100 HCs from Mexico were evaluated with the Norma Latina battery. The following analyses were conducted: 1) low-percentiles of each participant were calculated, 2) Area Under the Curve was used to determine whether the battery discriminated between PwMS and HCs, 3) four composite scores were calculated, and student's t-test was used to compare groups according to these domains. RESULTS: PwMS obtained a greater number of impaired scores compared to HCs, principally in executive function. The battery successfully discriminated between PwMS and HCs, with the strongest capacity to discriminate in the executive functions, and the weakest in memory. CONCLUSION: Establishing validation of a neuropsychological battery for Mexican PwMS will help to more accurately detect cognitive alterations, which will guide the decisions of professionals in terms of cognitive rehabilitation.

The Utility of the Patient Health Questionnaire (PHQ-9) Sleep Disturbance Item as a Screener for Insomnia in Individuals With Moderate to Severe Traumatic Brain Injury.

OBJECTIVE: To examine the utility of the sleep disturbance item of the Patient Health Questionnaire-9 (PHQ-9) as a screening tool for insomnia among individuals with moderate to severe traumatic brain injury (TBI). SETTING: Telephone interview. PARTICIPANTS: A sample of 248 individuals with a history of moderate to severe TBI participated in an interview within 2 years of their injury. DESIGN: Observational, cross-sectional analysis. MAIN MEASURES: The PHQ-9 was administered along with the Insomnia Severity Index, Pittsburgh Sleep Quality Index, Sleep Hygiene Index, Epworth Sleepiness Scale, and the Insomnia Interview Schedule. RESULTS: Receiver operating characteristic curve analysis was conducted for the PHQ-9 sleep item rating against a set of insomnia criteria to determine an optimal cutoff score. A cutoff of 2 on the PHQ-9 sleep item maximized sensitivity (76%) and specificity (79%), with an area under the curve of 0.79 (95% CI, 0.70-0.88). The 2 groups formed using this cutoff differed significantly on all sleep measures except the Epworth Sleepiness Scale. CONCLUSIONS: The PHQ-9 sleep item may serve as a useful screener to allow for detection of potential sleep disturbance among individuals with moderate to severe TBI. Those who screen positive using this item included in a commonly used measure of depression can be prioritized for further and more comprehensive assessment of sleep disorders.

Examining the Use of a Rest-Activity Ratio in a Pediatric Rehabilitation Setting.

OBJECTIVE: To examine the relationship between an estimate of sleep-wake regulation derived from actigraphy and determine whether it would be sensitive to neurocognitive dysfunction associated with acquired brain injury (ABI) in a pediatric rehabilitation sample. DESIGN: Cross-sectional design. SETTING: Inpatient pediatric rehabilitation facility. PARTICIPANTS: A sample (N=43) of 31 males (72.1%) and 12 females (27.9%) admitted to a pediatric rehabilitation hospital wore an actigraph (wrist accelerometer) for 1 week. Participant ages ranged from 8 to 17 years (mean, 13.1y; SD, 2.7y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Raw actigraphy activity counts in 1-minute epochs were used to derive a rest-activity ratio over each 24-hour period; a 5-day average value was calculated for Monday through Friday. Brain injury status was derived through medical record review, resulting in the formation of 3 groups: traumatic brain injury (n=14), nontraumatic brain injury (n=16), and a non-ABI control group (n=13). Functional status was measured using FIM for children (WeeFIM) Cognitive and Motor scores extracted from the medical records. RESULTS: Unadjusted models showed a significant main group effect for brain injury status (P=.012). Compared with controls, the rest-activity ratio was significantly lower in both the traumatic brain injury (P=.005), and nontraumatic brain injury (P=.023) groups. However, the main group effect was no longer significant in an adjusted model controlling for WeeFIM Cognitive and WeeFIM Motor scores at admission. In the context of the adjusted model, there was a significant relationship between the rest-activity ratio and WeeFIM Cognitive scores at admission. CONCLUSIONS: Individuals with lower functional status at admission, especially in the cognitive domain, had lower rest-activity ratios, suggesting poorer sleep-wake regulation. Similar to findings in adults with ABI, this ratio may have utility in tracking sleep-wake regulation in the pediatric rehabilitation setting. Future studies should investigate sensitivity to change over the course of recovery and responsiveness to clinical interventions to improve sleep.

Factor analysis of the Neurobehavioral Symptom Inventory among a sample of Spanish-speakers.

ABSTRACTA study was conducted to examine the factor structure of the Neurobehavioral Symptom Inventory (NSI) among a large community sample of 729 Spanish-speakers from the Continental United States (n = 174, 23.9%), Latin America (n = 465, 63.8%), and Spain (n = 90, 12.3%) The sample was 62.1% female, had at least 10 years of formal education, and ranged in age from 18 to 65 years (M = 36.7, SD = 12.5). The sample was randomly split into two groups with comparable demographics for a sequential analysis that consisted of an exploratory factor analysis on the first subsample followed by a confirmatory factor analysis within a second validation subsample. Results demonstrated a high internal consistency reliability for the Spanish version of the NSI, and a three-factor solution was supported with somatic, affective, and cognitive factors. Findings were comparable to prior studies with the English version of the NSI providing preliminary support for the construct validity of this measure among a large sample of Spanish-speakers. Further study is needed to determine the criterion-related validity of the individual factors as separate subscales and to examine the appropriateness of this measure for individuals with lower levels of education.

Network Analysis of Neurobehavioral Symptom Patterns in an International Sample of Spanish-Speakers with a History of COVID-19 and Controls.

(1) Background: Psychometric network analysis provides a novel statistical approach allowing researchers to model clusters of related symptoms as a dynamic system. This study applied network analysis to investigate the patterns of somatic, cognitive, and affective neurobehavioral symptoms in an international sample of Spanish-speaking individuals with a history of COVID-19 positivity and non-COVID controls; (2) methods: the sample (n = 1093) included 650 adults from 26 countries who reported having previously tested positive for COVID-19 (COVID+) through a viral and/or antigen test (average of 147 days since diagnosis). The control group (COVID-) was comprised of 443 adults from 20 countries who had completed the survey prior to the COVID-19 pandemic; (3) results: relative to the COVID- network, the COVID+ network was very well-connected, such that each neurobehavioral symptom was positively connected to the network. The organize-to-headache and dizzy-to-balance connections in the COVID+ network were stronger than in the COVID- network. The hearing, numbness, and tense symptoms were more central to the COVID+ network with the latter connected to the sleep, fatigue, and frustrated symptoms. The COVID- network was largely disjointed, with most of the somatosensory symptoms forming their own cluster with no connections to other symptom groups and fatigue not being connected to any other symptom. The cognitive and affective symptoms in the COVID- network were also largely connected to symptoms from within their own groups; (4) conclusions: These findings suggest that many of the long-term neurobehavioral symptoms of COVID-19 form a discernable network and that headaches, frustration, hearing problems, forgetfulness, and tension are the most central symptoms. Cognitive and behavioral rehabilitation strategies targeting these central symptom network features may hold promise to help fracture the lingering symptom network of COVID-19.

Assistive Technology Workplace Accommodation and Employment among Diverse Populations with Disabilities: Does Race/Ethnicity Matter?

The purpose of this study was to examine the relationship between assistive technology workplace accommodation (AT-WA) usage and employment status among racial/ethnic populations with disabilities. Chi-square tests and logistic regression were used to analyze secondary data from the 2015 Kessler Foundation National Employment and Disability Survey (KFNEDS). Results indicated that significantly more consumers who used AT-WA were currently working, and a significantly greater proportion of them were White. Moreover, a significantly lower proportion of those who did not use AT-WA had less expected odds of being currently employed. Specific implications are discussed to inform practices, policy, and/or future research.

Primary Language and Participation Outcomes in Hispanics With Traumatic Brain Injury: A Traumatic Brain Injury Model Systems Study.

OBJECTIVE: To examine the relationship between primary language and participation outcomes in English- and Spanish-speaking persons with complicated mild to severe traumatic brain injury (TBI) at 1 year post-injury. SETTING: Community following discharge from inpatient rehabilitation. PARTICIPANTS: A total of 998 Hispanic participants with outcomes available at year 1 follow-up; 492 (49%) indicated English as their primary language and 506 (51%) indicated Spanish as their primary language. DESIGN: Prospective, multicenter, cross-sectional, observational cohort study. MAIN MEASURES: Community participation at 1 year post-injury was assessed by 3 domains of the Participation Assessment with Recombined Tools-Objective (PART-O): Out and About, Productivity, and Social Relations. RESULTS: Unadjusted group comparisons showed better participation outcomes for English versus Spanish speakers for all PART-O domains and for the Balanced Total score. After controlling for relevant covariates, English-speaking participants had significantly better PART-O Balanced Total scores and better scores on the Social Relations domain, although effect sizes were small. CONCLUSIONS: Hispanic persons with TBI whose primary language is Spanish may require greater assistance integrating socially back into their communities after TBI. However, potential cultural differences in value placed on various social activities must be considered. Potential cultural bias inherent in existing measures of participation should be investigated in future studies.

Race/Ethnicity and Community Participation Among Veterans and Service Members With Traumatic Brain Injury: A VA Traumatic Brain Injury Model Systems Study.

OBJECTIVE: To examine racial/ethnic disparities in community participation among veterans and active duty service members with traumatic brain injury (TBI). SETTING: Five Department of Veterans Affairs (VA) TBI Model Systems (TBIMS) Polytrauma Rehabilitation Centers (PRCs). Participants: Three hundred forty-two community-dwelling adults (251 White, 34 Black, and 57 Hispanic) with TBI enrolled in the VA TBIMS National Database who completed a 1-year follow-up interview. Mean age was 38.6 years (range, 19-84 years). DESIGN: Cross-sectional analysis of a prospective observational cohort study. Main Measures: Community participation at 1 year postinjury assessed by 3 domains of the Participation Assessment with Recombined Tools-Objective (PART-O): Out & About, Productivity, and Social Relations. RESULTS: Significant differences were observed among race/ethnicity groups in PART-O Productivity and Out & About domains without controlling for relevant participant characteristics; Productivity scores were significantly higher for non-Hispanic Black than for non-Hispanic White participants (t = 2.40, P = .0169). Out & About scores were significantly higher for Hispanic than for non-Hispanic White participants (t = 2.79, P = .0056). However, after controlling for demographic, injury severity, and 1-year follow-up characteristics, only differences in the Out & About domain remained statistically significant (t = 2.62, P = .0094), with scores being significantly higher for Hispanics than for non-Hispanic Whites. CONCLUSIONS: The results, which differ from findings from studies conducted in non-VA healthcare settings where there are greater racial/ethnic disparities in participation outcomes, could reflect differences between military and civilian samples that may reduce disparities.

Cognitive-Communication Predictors of Employment Outcomes 1 and 5 Years Posttraumatic Brain Injury.

OBJECTIVE: To examine changes in functional memory, problem solving, comprehension, expression, and social communication over the first 2 years posttraumatic brain injury (TBI) and the ability of each to predict return to work (RTW) outcomes at 1 year and 5 years postinjury. DESIGN: Secondary analysis of data from a multicenter longitudinal cohort study. SETTING: Acute inpatient rehabilitation facilities and community follow-up. PARTICIPANTS: A total of 3543 individuals between 16 and 60 years of age who were competitively employed at the time of TBI and had completed year 1, year 2, and year 5 postinjury follow-ups. MAIN OUTCOME MEASURES: Year 1 and year 5 RTW status (± competitively employed) at the time of study completion. RESULTS: Greater function across each of the 5 cognitive-communication abilities was associated with RTW success at 1 year and 5 years post-TBI. At discharge, these 5 abilities showed comparable odds of predicting later employment. At year 1 and year 2 follow-ups, independence with problem solving was the most predictive of employment 5 years post-TBI, followed by social interaction, memory, expression, and comprehension. CONCLUSIONS: An increased rehabilitation focus on functional memory, problem solving, comprehension, expression, and social interaction post-TBI has the potential to improve RTW outcomes.

Assessing lifetime exposure to traumatic brain injury among an international sample of Spanish speakers.

BACKGROUND: With structured interviews being an established method for assessing one's exposure to traumatic brain injury across their lifetime, effective assessment tools are needed to serve the large population of Spanish speakers in the U.S. and abroad. OBJECTIVE: To obtain preliminary evidence of validity for a Spanish version of a web-based, structured interview designed to assess lifetime exposure to TBI. METHODS: A sample of 720 Spanish-speaking individuals between the ages of 18 through 65 from the continental U.S. (34.3%), South America (30.8%), the Caribbean (12.6%), Spain (12.4%), and Mexico and Central America (9.9%) completed an online survey containing the Ohio State University Traumatic Brain Injury Identification Method (Self-Administered-Brief; OSU TBI-ID SAB), Neurobehavioral Symptom Inventory, and PROMIS Cognitive Concerns Scale. RESULTS: Indices of severity of worst TBI, time since most recent TBI, and multiple injuries demonstrated expected relationships with neurobehavioral symptoms such that greater symptom reporting was observed among those who had more severe injuries, more recent injuries, and multiple injuries over a period of time. CONCLUSIONS: Findings provide preliminary evidence of validity for three of the indices derived from OSU TBI-ID SAB among Spanish-speaking individuals. Further study is needed to assess other aspects of this instrument to pave the way for further epidemiological studies involving lifetime exposure to TBI among Spanish-speaking individuals across the U.S., Spain, and Latin America.
