Associations of Nightmares and Sleep Disturbance With Neurobehavioral Symptoms Postconcussion.

OBJECTIVE: This study investigates the association of nightmares beyond general sleep disturbance on neurobehavioral symptoms in adults with mild traumatic brain injury (mTBI). DESIGN: Secondary analysis of a concussion cohort study. PARTICIPANTS: One hundred and eleven adults older than 20 years with mTBI were recruited from a specialized concussion treatment center. MAIN MEASURES: Behavioral Assessment Screening Tool, Pittsburgh Sleep Quality Index, and self-report of nightmare frequency in the past 2 weeks. RESULTS: Among adults with mTBI, nightmares accounted for the greatest amount of variability in negative affect (ß = .362, P < .001), anxiety (ß = .332, P < .001), and impulsivity (ß = .270, P < .001) after adjusting for age and sex. Overall sleep disturbance had the strongest association with depression (ß = .493, P < .001), fatigue (ß = .449, P < .001), self-reported executive dysfunction (ß = .376, P < .001), and overall burden from concussive symptoms (ß = .477, P < .001). CONCLUSIONS: Nightmares and sleep disturbance are differentially associated with variance in neurobehavioral symptoms. Nightmares were independently associated with neurobehavioral symptoms representing an excess of normal functioning (eg, anxiety, impulsivity), while general sleep disturbance was associated with neurobehavioral symptoms representing functioning below normal levels (eg, depression, fatigue, self-reported executive dysfunction). Clinical and research implications are discussed.

The Behavioral Assessment Screening Tool for Mobile Health (BASTmHealth): Development and Compliance in 2 Weeks of Daily Reporting in Chronic Traumatic Brain Injury.

OBJECTIVES: To develop and evaluate the feasibility of a short form of the Behavioral Assessment Screening Tool (BASTmHealth) for high frequency in situ self-reported assessment of neurobehavioral symptoms using mobile health technology for community-dwelling adults with traumatic brain injury (TBI). DESIGN: Prospective, repeated-measures study of mHealth assessment of self-reported neurobehavioral symptoms in adults with and without a lifetime history of TBI over a 2-week period. SETTING: Community. PARTICIPANTS: Community-dwelling adults with (n=52) and without (n=12) a lifetime TBI history consented to the study (N=64). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: BASTmHealth subscales (2-items each): negative affect, fatigue, executive function, substance abuse, impulsivity; feasibility measured via compliance (assessments assigned/assessments completed) and participant-reported usability. RESULTS: We developed the 10-item BASTmHealth as a screener for high frequency in situ self-reported assessment of neurobehavioral symptoms leveraging mHealth. Compliance for 2 weeks of BASTmHealth supports its feasibility. Fifty-six of 64 participants (87.5%) who completed baseline assessments completed the 2 weeks of daily assessments; all 8 participants who did not complete ecological momentary assessment had a history of TBI. Overall compliance was 81.4% (496 completed of 609 assigned assessments) among all 52 participants with TBI and 96.7% (494 completed of 511 assigned assessments) among the 44 who completed any daily measures, compared with 91.8% (135 completed of 147 assigned assessments) among those with no TBI history. Participants thought the daily surveys were easy to understand and complete and the number of prompts were reasonable. CONCLUSIONS: Conducting daily high-frequency in situ self-reported assessment of neurobehavioral symptoms using the BASTmHealth is feasible among individuals with and without a lifetime history of TBI. Developing and evaluating self-reported assessments for community-based assessment is a critical step toward expanding remote clinical monitoring systems to improve post-TBI outcomes.

Neurobehavioral Symptoms and Heart Rate Variability: Feasibility of Remote Collection Using Mobile Health Technology.

OBJECTIVES: To determine the covariance of heart rate variability (HRV) and self-reported neurobehavioral symptoms after traumatic brain injury (TBI) collected using mobile health (mHealth) technology. SETTING: Community. PARTICIPANTS: Adults with lifetime history of TBI (n = 52) and adults with no history of brain injury (n = 12). DESIGN: Two-week prospective ecological momentary assessment study. MAIN MEASURES: Behavioral Assessment Screening Tool (BASTmHealth) subscales (Negative Affect, Fatigue, Executive Dysfunction, Substance Abuse, and Impulsivity) measured frequency of neurobehavioral symptoms via a RedCap link sent by text message. Resting HRV (root mean square of successive R-R interval differences) was measured for 5 minutes every morning upon waking using a commercially available heart rate monitor (Polar H10, paired with Elite HRV app). RESULTS: Data for n = 48 (n = 38 with TBI; n = 10 without TBI) participants were included in covariance analyses, with average cross-correlation coefficients (0-day lag) varying greatly across participants. We found that the presence and direction of the relationship between HRV and neurobehavioral symptoms varied from person to person. Cross-correlation coefficients r ≤ -0.30, observed in 27.1% to 29.2% of participants for Negative Affect, Executive Dysfunction, and Fatigue, 22.9% of participants for Impulsivity, and only 10.4% of participants for Substance Abuse, supported our hypothesis that lower HRV would covary with more frequent symptoms. However, we also found 2.0% to 20.8% of participants had positive cross-correlations (r ≥ 0.30) across all subscales, indicating that higher HRV may sometimes correlate with more neurobehavioral symptoms, and 54.2% to 87.5% had no significant cross-correlations. CONCLUSIONS: It is generally feasible for community-dwelling adults with and without TBI to use a commercially available wearable device to capture daily HRV measures and to complete a short, electronic self-reported neurobehavioral symptom measure for a 2-week period. The covariance of HRV and neurobehavioral symptoms over time suggests that HRV could be used as a relevant physiological biomarker of neurobehavioral symptoms, though how it would be interpreted and used in practice would vary on a person-by-person and symptom domain basis and requires further study.

Use of mHealth Technology for Patient-Reported Outcomes in Community-Dwelling Adults with Acquired Brain Injuries: A Scoping Review.

The purpose of our scoping review was to describe the current use of mHealth technology for long-term assessment of patient-reported outcomes in community-dwelling individuals with acquired brain injury (ABI). Following PRISMA guidelines, we conducted a scoping review of literature meeting these criteria: (1) civilians or military veterans, all ages; (2) self-reported or caregiver-reported outcomes assessed via mobile device in the community (not exclusively clinic/hospital); (3) published in English; (4) published in 2015-2019. We searched Ovid MEDLINE(R) < 1946 to 16 August 2019, MEDLINE InProcess, EPub, Embase, and PsycINFO databases for articles. Thirteen manuscripts representing 12 distinct studies were organized by type of ABI [traumatic brain injury (TBI) and stroke] to extract outcomes, mHealth technology used, design, and inclusion of ecological momentary assessment (EMA). Outcomes included post-concussive, depressive, and affective symptoms, fatigue, daily activities, stroke risk factors, and cognitive exertion. Overall, collecting patient-reported outcomes via mHealth was feasible and acceptable in the chronic ABI population. Studies consistently showed advantage for using EMA despite variability in EMA timing/schedules. To ensure best clinical measurement, research on post-ABI outcomes should consider EMA designs (versus single time-point assessments) that provide the best timing schedules for their respective aims and outcomes and that leverage mHealth for data collection.

The benefits of an unsupervised exercise program in persons with well-healed burn injuries within the International Classification of Functioning, Disability and Health (ICF).

Vast improvements in the survival rates following burn injuries has led to a greater number of patients living with a wide range of long-term impairments, activity limitations, and participation constraints. Therefore, long-term care is critical in this clinical population and necessitates appropriate rehabilitation strategies to maximize an individual's overall health. The purpose of this study was to test the hypothesis that the extent to which outcomes within the International Classification of Functioning, Disability, and Health (ICF) framework are improved following 6 months of unsupervised exercise training is influenced by the severity of a burn injury (i.e., percent body surface area injured). Outcome variables representing the dimensions of the ICF, body functions & structure, activity, and participation, were collected pre- and post- 6 months of exercise training in three groups of participants: non-injured control subjects (N = 11), subjects with moderate-level well-healed burn injuries (N = 13, 26 ± 6% body surface area burned), and subjects with high-level well-healed burn injuries (N = 20, 58 ± 15% body surface area burned). Exercise training improved lower extremity strength (changes in peak torque/kg body mass at 90 degrees/sec flexion: 30 ± 5% and extension: 36 ± 4%, p < 0.05) and functional activities (changes in sit to stand: -9 ± 4% and ascend stairs: -4 ± 1%; p < 0.05) in all groups. For outcome variables representing ICF levels of body functions & structure and activity, there were no differences at baseline or improvements made between the groups after training. That said, with the exception of the domain of functional activity (reported 17 ± 34% improvement in the high-level burn cohort, p < 0.05), no changes were revealed in the participation level of ICF indexed by health-related quality of life questionnaires. These findings support the utilization of a 6-month unsupervised exercise training program in the long-term rehabilitation of individuals with burn injuries; that is, improvements in body functions & structure and activity can be achieved with an exercise regimen regardless of the severity of burn injury.

Neurobehavioral symptoms by gender and experience of nightmares after traumatic brain injury.

PURPOSE/OBJECTIVE: The purpose of this study is to assess how neurobehavioral symptoms following traumatic brain injury (TBI) may differ based on gender and the experience of nightmares. Research Method/Design: This cross-sectional study of community-dwelling adults ≥ 3 months post-TBI (n = 110) assessed differences in neurobehavioral symptoms between women (n = 41) and men (n = 69) by experience of nightmares. Outcome measures included the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Behavioral Assessment Screening Tool subscales for negative affect, substance abuse, executive functioning, fatigue, impulsivity, and maladaptive coping. RESULTS: N = 22 participants (n = 7 women, n = 15 men) experienced nightmares at least "sometimes" over the past 2 weeks. Nightmares were associated with more substance abuse, negative affect, fatigue, maladaptive coping, depressive symptoms, and anxiety symptoms (ps < .02). Women reported more negative affect, maladaptive coping, depressive symptoms, and anxiety symptoms (ps < .05) than men. Men experiencing nightmares reported more substance use than men without nightmares (p = .036), a difference not seen in women (p = .233). Women experiencing nightmares reported more impulsivity than women without nightmares (p = .028), a difference not seen in men (p = .559). CONCLUSIONS/IMPLICATIONS: Nightmares, post-TBI, are associated with more neurobehavioral symptoms. However, symptom patterns associated with nightmares may differ by gender. Nightmares may be a symptom of, or contribute to, sleep disruptions post-TBI or may indicate other conditions, like posttraumatic stress disorder. Future research should examine gender differences in neurobehavioral symptoms post-TBI in the context of nightmares and/or sleep disorders.

"Descubriendo Soluciones Juntos"-An argument for adapting problem-solving training for Latinx care partners after traumatic brain injury (TBI).

PURPOSE/OBJECTIVE: This commentary demonstrates the need for culturally adapted interventions to support informal caregivers (care partners) of adults with traumatic brain injuries (TBI), proposes and supports an evidence-based intervention, Problem-Solving Training (PST), uniquely suitable for cultural adaptation for Latinx care partners, and describes several considerations and concrete suggestions for initial cultural adaption of PST for Latinx care partners of adults with TBI. RESULTS: Caregiving among Latinxs is rooted in cultural values and norms that may facilitate or challenge family coping and adaptation after TBI in the United States. Evidence-based interventions to address emotional distress, health, and caregiver burden are needed for Latinx care partners, but must first be translated and adapted to address language and cultural values. Compared with other cognitive and behavioral evidence-based interventions, PST is ideal for cultural adaptation, as the problem-solving process is driven by, and therefore sensitive and responsive to, care partners and their individual values and situations. CONCLUSIONS/IMPLICATIONS: Adapting evidence-based problem-solving interventions like PST ("Descubriendo Soluciones Juntos") to be culturally tailored and culturally sensitive for Spanish-speaking Latinx care partners of adults with TBI could reduce existing health disparities and improve the health, well-being, and quality of life of these care partners.

Neurobehavioral Symptoms in Community-Dwelling Adults With and Without Chronic Traumatic Brain Injury: Differences by Age, Gender, Education, and Health Condition.

Neurobehavioral symptoms after Traumatic Brain Injury (TBI) are prevalent, persist for many years, and negatively affect long-term health, function, and quality of life. Symptoms may differ based on age, gender, education, race, ethnicity, and injury severity. To better understand neurobehavioral functioning after TBI, we need a comprehensive picture of emotional, cognitive, and behavioral symptoms in the context of personal factors that may affect these symptoms. We also need to understand the extent to which these symptoms are specific to TBI, shared across other neurological conditions, or attributable to factors outside of the injury itself. We collected neurobehavioral symptoms via the self-reported Behavioral Assessment Screening Tool (BAST) in a National Cohort of English (n = 2,511) and Spanish speaking (n = 350) community-dwelling adults with and without chronic TBI and other neurological and mental health conditions. The primary focus of the present study was to comprehensively describe neurobehavioral symptoms in adults with and without TBI, broken down by gender and health conditions and then further by age group or educational attainment. As expected, participants with TBI reported more symptoms than Healthy Controls. Regardless of condition, women reported more fatigue, while men reported more substance abuse and impulsivity. Hispanic participants reported more neurobehavioral symptoms than non-Hispanic participants did across health conditions, though primarily Spanish-speakers reported fewer symptoms than English-speakers, suggesting that level of acculturation may contribute to symptom reporting. These data provide a comprehensive characterization of neurobehavioral symptoms in adults with TBI and adults without TBI (healthy controls, adults with other neurological conditions, and adults with mental health conditions).

Care partner problem solving training (CP-PST) for care partners of adults with traumatic brain injury during inpatient rehabilitation: Study protocol for a multisite, randomized, single-blind clinical feasibility trial.

Traumatic brain injury (TBI) often leads to immediate and chronic functional impairments that affect care partners, or those providing physical and/or emotional support to individuals with TBI. The many challenges associated with being a care partner often lead to caregiver burden and can compromise the well-being and quality of life of care partners and individuals with TBI under their care. Equipping care partners with problem-solving skills could facilitate and sustain their transition into this supportive role. Problem-solving training (PST) has demonstrated efficacy for providing such skills to care partners of individuals with TBI after discharge from inpatient rehabilitation. We propose that PST delivered to care partners during inpatient rehabilitation of individuals with TBI will provide care partners with the skills to manage their caregiving roles across the transition from hospital to home. Herein, we describe the methodology of a current randomized controlled trial that examines the feasibility and efficacy of PST plus TBI education compared to TBI education alone to improve care partner burden, emotional distress, and adaptive coping when delivered during the inpatient rehabilitation stay of individuals with moderate-severe TBI.

Feasibility Study of Problem-Solving Training for Care Partners of Adults With Traumatic Brain Injury, Spinal Cord Injury, Burn Injury, or Stroke During the Inpatient Hospital Stay.

OBJECTIVE: To determine the feasibility of delivering an evidence-based self-management intervention, problem-solving training (PST), to care partners of individuals with traumatic brain injury (TBI), spinal cord injury (SCI), burn injury, or stroke during the inpatient hospital stay. DESIGN: In this single group pre-post intervention pilot feasibility study. SETTING: Inpatient rehabilitation or acute care and community. PARTICIPANTS: Care partners (spouse or partner, family member, friend who is in any way responsible for the health or well-being of the care recipient) of individuals with TBI, SCI, burn injury, or stroke (N=39). INTERVENTION: PST is a metacognitive self-management intervention that teaches individuals a global strategy for addressing self-selected problems. Participants received up to 6 sessions of PST in person or via telephone during their care recipient's inpatient stay. MAIN OUTCOME MEASURES: We measured feasibility of recruitment, intervention delivery, and postintervention use of a smartphone app (Care Partner Problem Solving [CaPPS]) and participant satisfaction (Client Satisfaction Questionnaire [CSQ]) and engagement (Pittsburgh Rehabilitation Participation Scale [PRPS]) with the intervention. RESULTS: Of 39 care partners approached, n=10 (25.6%) were ineligible. Of n=29 (74.4%) who were eligible, n=17 (58.6%) refused, and n=12 (41.4%) consented, of whom n=8 (66.7%) completed ≥3 PST sessions. Not perceiving any benefit was the most common reason for refusal, followed by no interest in research. Participants were very satisfied with PST (CSQ mean=3.35, SD=0.60), reported strong working alliance (Working Alliance Inventory mean=6.8, SD=3.1), and demonstrated very good engagement (PRPS mean=4.75, SD=1.41). CaPPS was downloaded and used by only n=3 participants. CONCLUSIONS: Delivering a self-management intervention to care partners during the care recipient's acute hospital stay is feasible for a subset of potential participants. Short lengths of stay, language fluency, and perceiving no potential benefit were noted barriers. Boosters via smartphone app have potential, but several barriers must first be overcome.

Cohort Differences in Neurobehavioral Symptoms in Chronic Mild to Severe Traumatic Brain Injury.

Our understanding of neurobehavioral symptoms after traumatic brain injury (TBI) largely relies on data gathered in studies conducted at academic medical centers or large clinical centers with research infrastructure. Though this often provides a well-characterized clinical sample, it may also introduce bias based on geographic locations served by these institutions and personal factors associated with patient access to these institutions. We collected neurobehavioral symptoms via the self-reported Behavioral Assessment Screening Tool (BAST) in a National TBI Cohort (n = 263) and a Medical Center TBI Cohort (n = 218) of English-speaking community-dwelling adults with chronic TBI. The primary focus of the present study was to compare demographics and neurobehavioral symptom reporting across the two cohorts and to discuss the implications of any such differences on interpretation of symptom scores. Across all BAST subscales (Negative Affect, Fatigue, Executive Function, Impulsivity, and Substance Abuse), participants in the National TBI Cohort reported significantly more frequent symptoms than those in the Medical Center TBI Cohort (p's < 0.001). Participants in the National TBI Cohort were more likely to be non-White and Hispanic compared to the Medical Center TBI Cohort, and those with mild TBI in the National TBI Cohort were more likely to have less than a high school education than those with mild TBI in the Medical Center TBI Cohort. Individuals with TBI recruited through academic and clinical institutions may not be representative of individuals with TBI living across the United States.
