Objective

To assess the association between perceived stigma and discrimination and caregiver strain, caregiver well-being, and patient community reintegration.

Design

A cross-sectional survey study of 564 informal caregivers of U.S. military service veterans of wars in Iraq and Afghanistan who experienced traumatic brain injuries or polytrauma (TBI/PT).

Setting

Care settings of community-dwelling former inpatients of U.S. Department of Veterans Affairs Polytrauma Rehabilitation Centers.

Participants

Caregivers of former inpatients (N=564), identified through next-of-kin records and subsequent nominations.

Interventions

Not applicable.

Main Outcome Measures

Caregiver strain, depression, anxiety, loneliness, and self-esteem; as well as care recipient community reintegration, a key aspect of TBI/PT rehabilitation.

Results

Family stigma was associated with strain, depression, anxiety, loneliness, lower self-esteem, and less community reintegration. Caregiver stigma-by-association was associated with strain, depression, anxiety, loneliness, and lower self-esteem. Care recipient stigma was associated with caregiver strain, depression, anxiety, loneliness, lower self-esteem, and less community reintegration.

Conclusions

Perceived stigma may be a substantial source of stress for caregivers of U.S. military veterans with TBI/PT, and may contribute to poor outcomes for the health of caregivers and for the community reintegration of the veterans for whom they provide care.  相似文献

Objective

To comprehensively estimate the diagnostic accuracy and reliability of the Department of Veterans Affairs (VA) Traumatic Brain Injury (TBI) Clinical Reminder Screen (TCRS).

Design

Cross-sectional, prospective, observational study using the Standards for Reporting of Diagnostic Accuracy criteria.

Setting

Three VA Polytrauma Network Sites.

Participants

Operation Iraqi Freedom, Operation Enduring Freedom veterans (N=433).

Main Outcome Measures

TCRS, Comprehensive TBI Evaluation, Structured TBI Diagnostic Interview, Symptom Attribution and Classification Algorithm, and Clinician-Administered Posttraumatic Stress Disorder (PTSD) Scale.

Results

Forty-five percent of veterans screened positive on the TCRS for TBI. For detecting occurrence of historical TBI, the TCRS had a sensitivity of .56 to .74, a specificity of .63 to .93, a positive predictive value (PPV) of 25% to 45%, a negative predictive value (NPV) of 91% to 94%, and a diagnostic odds ratio (DOR) of 4 to 13. For accuracy of attributing active symptoms to the TBI, the TCRS had a sensitivity of .64 to .87, a specificity of .59 to .89, a PPV of 26% to 32%, an NPV of 92% to 95%, and a DOR of 6 to 9. The sensitivity was higher for veterans with PTSD (.80–.86) relative to veterans without PTSD (.57–.82). The specificity, however, was higher among veterans without PTSD (.75–.81) relative to veterans with PTSD (.36–.49). All indices of diagnostic accuracy changed when participants with questionably valid (QV) test profiles were eliminated from analyses.

Conclusions

The utility of the TCRS to screen for mild TBI (mTBI) depends on the stringency of the diagnostic reference standard to which it is being compared, the presence/absence of PTSD, and QV test profiles. Further development, validation, and use of reproducible diagnostic algorithms for symptom attribution after possible mTBI would improve diagnostic accuracy.  相似文献

Objective

To test the feasibility and validity of an online version of an established interview designed to determine a lifetime history of traumatic brain injury (TBI).

Design

Cross-sectional.

Setting

General community.

Participants

A volunteer sample of individuals (N= 265) from the general population across the United States.

Interventions

Not applicable.

Main Outcome Measure(s)

Online version of the Ohio State University Traumatic Brain Injury Identification Method, Rivermead Postconcussion Symptoms Questionnaire (RPQ), Patient-Reported Outcomes Measurement Information System Cognitive Concerns Scale.

Results

The measure was completed by 89.4% of the sample with most participants completing the measure in <8 minutes. After controlling for age, sex, psychiatric history, drug or alcohol history, and history of developmental disability, worst TBI severity was significantly associated with scores on the RPQ, F(2,230)=4.56, P=.011, and having a TBI within the past 2 years was associated with higher scores on the cognitive factor subscale of the RPQ, F(1,75)=7.7, P=.007.

Conclusions

The online administration of the Ohio State University Traumatic Brain Injury Identification Method appears to be feasible in the general population. Preliminary validity was demonstrated for the indices of worst TBI severity and time since most recent TBI.  相似文献

Objectives

To develop, for versions completed by individuals with traumatic brain injury (TBI) and an observer, a more precise metric for the Neuropsychiatric Inventory (NPI) Irritability and Aggression subscales using all behavioral item ratings for use with individuals with TBI and to address the dimensionality of the represented behavioral domains.

Design

Rasch and confirmatory factor analyses of retrospective baseline NPI data from 3 treatment studies.

Setting

Postacute rehabilitation clinic.

Participants

NPI records (N = 525) consisting of observer ratings (n = 287) and self-ratings (n = 238) by participants with complicated mild, moderate, or severe TBI at least 6 months postinjury.

Interventions

Not applicable.

Main Outcome Measures

Frequency and severity ratings from NPI Irritability/Lability and Agitation/Aggression subscales.

Results

Confirmatory factor analyses of both observer and participant ratings showed good fit for either a 1-factor or a 2-factor solution. Consistent with this, the Rasch model also fit the data well with aggression items indicating the more severe end of the construct and irritability items populating the milder end.

Conclusions

Irritability and aggression appear to represent different levels of severity of a single construct. The derived Rasch metric offers a measure of this construct based on responses to all specific items that is appropriate for parametric statistical analysis and may be useful in research and clinical assessments of individuals with TBI.  相似文献

Objective

To describe and synthesize the literature on adult traumatic brain injury (TBI) family caregiver and dyad intervention. TBI is a common injury that has a significant long-term impact, and is sometimes even characterized as a chronic condition. Informal (ie, unpaid) family caregivers of adults with TBI experience high rates of burnout, depression, fatigue, anxiety, lower subjective well-being, and poorer levels of physical health compared to noncaregivers. This study addresses the critical gap in the understanding of interventions designed to address the impact of TBI on adult patients and their family caregivers.

Data Sources

PubMed and MEDLINE.

Study Selection

Studies selected for review had to be written in English and be quasi-experimental or experimental in design, report on TBI caregivers, survivors with heavy involvement of caregivers, or caregiver dyads, involve moderate and severe TBI, and describe an intervention implemented during some portion of the TBI care continuum.

Data Extraction

The search identified 2171 articles, of which 14 met our criteria for inclusion. Of the identified studies, 10 were randomized clinical trials and 4 were nonrandomized quasi-experimental studies. A secondary search to describe studies that included individuals with other forms of acquired brain injury in addition to TBI resulted in 852 additional titles, of which 5 met our inclusion criteria.

Data Synthesis

Interventions that targeted the caregiver primarily were more likely to provide benefit than those that targeted caregiver/survivor dyad or the survivor only. Many of the studies were limited by poor fidelity, low sample sizes, and high risk for bias based on randomization techniques.

Conclusions

Future studies of TBI caregivers should enroll a more generalizable number of participants and ensure adequate fidelity to properly compare interventions.  相似文献

Objectives

To evaluate (1) the trajectory of resilience during the first year after a moderate-severe traumatic brain injury (TBI); (2) factors associated with resilience at 3, 6, and 12 months postinjury; and (3) changing relationships over time between resilience and other factors.

Design

Longitudinal analysis of an observational cohort.

Setting

Five inpatient rehabilitation centers.

Participants

Patients with TBI (N=195) enrolled in the resilience module of the TBI Model Systems study with data collected at 3-, 6-, and 12-month follow-up.

Interventions

Not applicable.

Main Outcome Measure

Connor-Davidson Resilience Scale.

Results

Initially, resilience levels appeared to be stable during the first year postinjury. Individual growth curve models were used to examine resilience over time in relation to demographic, psychosocial, and injury characteristics. After adjusting for these characteristics, resilience actually declined over time. Higher levels of resilience were related to nonminority status, absence of preinjury substance abuse, lower anxiety and disability level, and greater life satisfaction.

Conclusions

Resilience is a construct that is relevant to understanding brain injury outcomes and has potential value in planning clinical interventions.  相似文献

Background

Mental health problems are common after pediatric traumatic brain injury (TBI). Many patients in need of mental health services do not receive them, but studies have not consistently used prospective and objective methods or followed samples for more than 1 year.

Objective

To examine adolescents’ use of mental health services after TBI.

Design

Secondary analysis from multicenter prospective randomized controlled trial.

Setting

Five level 1 U.S. trauma centers.

Participants

Adolescents aged 12-17 years with moderate-to-severe TBI were recruited for a randomized clinical trial (n = 132 at baseline, 124 at 6 months, 113 at 12 months, and 101 at 18 months).

Methods

Participants were randomly assigned to counselor-assisted problem-solving or Internet resource comparison. Follow-up assessments were completed at 6, 12, and 18 months after baseline. Generalized estimating equations with a logit link were used to examine use of mental health services. Treatment group and participant impairment were examined as predictors of use.

Main Outcome Measurements

Mental health care use was measured with the Service Assessment for Children and Adolescents; daily functioning and clinical outcome with the Child and Adolescent Functional Assessment Scale; behavioral and emotional functioning with the Child Behavior Checklist; and executive dysfunction with the Behavior Rating Inventory of Executive Function.

Results

Use of mental health services ranged from 22% to 31% in the 2 years post-TBI. Participants with impairments were about 3 times more likely than those without impairments to receive services (odds ratio 4.61; 95% confidence interval 2.61-8.14; P < .001). However, 50%-68% of patients identified as impaired had unmet mental health care needs.

Conclusions

Less than one half of adolescents with behavioral health needs after TBI received mental health services. Future studies are needed to examine barriers associated with seeking services after TBI and psychoeducation as preventive care for this population.

Objectives

To describe the prevalence of cannabis use in an adult sample with spinal cord injury (SCI) or traumatic brain injury (TBI) in Colorado, and to describe the self-reported reasons and side effects of cannabis use in this sample.

Design

Mixed-methods observational study, using focus group data and telephone survey.

Setting

Community.

Participants

Colorado adults who sustained SCI or moderate to severe TBI and received services through Craig Hospital.

Interventions

None.

Main Outcome Measures

Survey.

Results

Focus group participants identified issues that were then included in the survey development. Seventy percent of the 116 participants surveyed reported cannabis use before their injury (67% SCI, 74% TBI) and 48% reported use after their injury (53% SCI, 45% TBI). Overall, the most common reason for use was recreational (67%), followed by reducing stress/anxiety (62.5%) and improving sleep (59%). Among the respondents with SCI, the most common reasons for use were to reduce spasticity (70%), recreation (63%), and to improve sleep (63%). Among those with TBI, reasons endorsed were recreational (72%), reducing stress/anxiety (62%), and improving sleep (55%). Smoking was the most common method of use.

Conclusions

A majority of this sample reported using cannabis before injury, and approximately half reported using cannabis after injury. Both groups reported recreational use, whereas the group with SCI also highly endorsed using cannabis to address chronic medical conditions. Clinicians should be aware of the high prevalence of cannabis use in these populations and the impact such use may have on the individual’s medical management. Further research in this area is needed.  相似文献

Objective

To examine the different sources of medications, the most common drug classes filled, and the characteristics associated with Medicare Part D pharmacy use in veterans with spinal cord injury/disorder (SCI/D).

Design

Retrospective, cross-sectional, observational study.

Setting

Outpatient clinics and pharmacies.

Participants

Veterans (N=13,442) with SCI/D using Medicare or Veteran Affairs pharmacy benefits.

Interventions

Not applicable.

Main Outcome Measures

Characteristics and top 10 most common drug classes were examined in veterans who (1) used VA pharmacies only; (2) used both VA and Medicare Part D pharmacies; or (3) used Part D pharmacies only. Chi-square tests and multinomial logistic regression analyses were used to determine associations between various patient variables and source of medications. Patient level frequencies were used to determine the most common drug classes.

Results

A total of 13,442 veterans with SCI/D were analyzed in this study: 11,788 (87.7%) used VA pharmacies only, 1281 (9.5%) used both VA and Part D pharmacies, and 373 (2.8%) used Part D pharmacies only. Veterans older than 50 years were more likely to use Part D pharmacies, whereas those with traumatic injury, or secondary conditions, were less associated with the use of Part D pharmacies. Opioids were the most frequently filled drug class across all groups. Other frequently used drug classes included skeletal muscle relaxants, gastric medications, antidepressants (other category), anticonvulsants, and antilipemics.

Conclusions

Approximately 12% of veterans with SCI/D are receiving medication outside the VA system. Polypharmacy in this population of veterans is relatively high, emphasizing the importance of health information exchange between systems for improved care for this medically complex population.  相似文献

Objective

To evaluate the effectiveness of a replicable group treatment program for improving social competence after traumatic brain injury (TBI).

Design

Multicenter randomized controlled trial comparing 2 methods of conducting a social competency skills program, an interactive group format versus a classroom lecture.

Setting

Community and veteran rehabilitation centers.

Participants

Civilian, military, and veteran adults with TBI and social competence difficulties (N=179), at least 6 months postinjury.

Interventions

The experimental intervention consisted of 13 weekly group interactive sessions (1.5h) with structured and facilitated group interactions to improve social competence, and the control consisted of 13 traditional classroom sessions using the same curriculum with brief supplemental individual sessions but without structured group interaction.

Main Outcome Measures

Profile of Pragmatic Impairment in Communication (PPIC), an objective behavioral rating of social communication impairments after TBI. LaTrobe Communication Questionnaire (LCQ), Goal Attainment Scale (GAS), Satisfaction with Life Scale, Posttraumatic Stress Disorder Checklist-C (PCL) civilian version, Brief Symptom Inventory 18 (BSI-18), Scale of Perceived Social Self-Efficacy (PSSE).

Results

Social competence goals (GAS) were achieved and maintained for most participants regardless of treatment method. Significant improvements in the primary outcome (PPIC) and 2 of the secondary outcomes (LCQ and BSI) were seen immediately posttreatment and at 3 months posttreatment in the alternative treatment arm only; however, these improvements were not significantly different between the group interactive structured treatment and alternative treatment arms. Similar trends were observed for PSSE and PCL-C.

Conclusions

Social competence skills improved for persons with TBI in both treatment conditions. The group interactive format was not found to be a superior method of treatment delivery in this study.  相似文献

Objective

To compare movement reaction time and joint kinematics between athletes with recent concussion and matched control recreational athletes during 3 functional tasks.

Design

Cross-sectional.

Setting

Laboratory.

Participants

College-aged recreational athletes (N=30) comprising 2 groups (15 participants each): (1) recent concussion group (median time since concussion, 126d; range, 28–432d) and (2) age- and sex-matched control group with no recent concussions.

Interventions

We investigated movement reaction time and joint kinematics during 3 tasks: (1) jump landing, (2) anticipated cut, and (3) unanticipated cut.

Main Outcome Measures

Reaction time and reaction time cost (jump landing reaction time–cut reaction time/jump landing reaction time×100%), along with trunk, hip, and knee joint angles in the sagittal and frontal planes at initial ground contact.

Results

There were no reaction time between-group differences, but the control group displayed improved reaction time cost (10.7%) during anticipated cutting compared with the concussed group (0.8%; P=.030). The control group displayed less trunk flexion than the concussed group during the nondominant anticipated cut (5.1° difference; P=.022). There were no other kinematic between-group differences (P≥.079).

Conclusions

We observed subtle reaction time and kinematic differences between individuals with recent concussion and those without concussion more than a month after return to activity after concussion. The clinical interpretation of these findings remains unclear, but may have future implications for postconcussion management and rehabilitation.  相似文献

Objective

To determine the extent to which the content of the Quality of Life in Neurological Disorders (Neuro-QoL) covers the International Classification of Functioning, Disability and Health (ICF) Core Sets for multiple sclerosis (MS), stroke, spinal cord injury (SCI), and traumatic brain injury (TBI) using summary linkage indicators.

Design

Content analysis by linking content of the Neuro-QoL to corresponding ICF codes of each Core Set for MS, stroke, SCI, and TBI.

Setting

Three academic centers.

Participants

None.

Interventions

None.

Main Outcome Measures

Four summary linkage indicators proposed by MacDermid et al were estimated to compare the content coverage between Neuro-QoL and the ICF codes of Core Sets for MS, stroke, MS, and TBI.

Results

Neuro-QoL represented 20% to 30% Core Set codes for different conditions in which more codes in Core Sets for MS (29%), stroke (28%), and TBI (28%) were covered than those for SCI in the long-term (20%) and early postacute (19%) contexts. Neuro-QoL represented nearly half of the unique Activity and Participation codes (43%–49%) and less than one third of the unique Body Function codes (12%?32%). It represented fewer Environmental Factors codes (2%?6%) and no Body Structures codes. Absolute linkage indicators found that at least 60% of Neuro-QoL items were linked to Core Set codes (63%?95%), but many items covered the same codes as revealed by unique linkage indicators (7%?13%), suggesting high concept redundancy among items.

Conclusions

The Neuro-QoL links more closely to ICF Core Sets for stroke, MS, and TBI than to those for SCI, and primarily covers activity and participation ICF domains. Other instruments are needed to address concepts not measured by the Neuro-QoL when a comprehensive health assessment is needed.  相似文献

Objective

To investigate the relation between posttraumatic stress (PTS) symptom severity and health-related quality of life (HRQoL) after severe traumatic brain injury (TBI).

Design

Longitudinal prospective multicenter, cohort study on severe TBI in Switzerland (2007–2011).

Setting

Hospital, rehabilitation unit, and/or patient’s living facility.

Participants

Patients with severe TBI (N=109) were included in the analyses. Injury severity was determined using the Abbreviated Injury Score of the head region after clinical assessment and initial computed tomography scan.

Interventions

Not applicable.

Main Outcome Measures

HRQoL (Medical Outcomes Study 12-Item Short-Form Health Survey Physical and Mental Component Summaries) and self-reported emotional, cognitive, and interpersonal functioning (Patient Competency Rating Scale for Neurorehabilitation).

Results

Multilevel models for patients >50 and ≤50 years of age revealed significant negative associations between PTS symptom severity and interpersonal functioning (P<.001 and P=.002), respectively. Among patients ≤50 years of age, PTS symptom severity was significantly associated with total functioning (P=.001) and emotional functioning (P<.001). Among all patients, PTS symptom severity was significantly associated with cognitive functioning (P<.001) and mental HRQoL (P=.01).

Conclusions

Findings indicate that PTS symptoms after severe TBI are negatively associated with HRQoL and emotional, cognitive, and interpersonal functioning.  相似文献

Background

Depression and traumatic brain injury (TBI) substantially contribute to the U.S. health care burden. Depression is a known risk factor for prolonged recovery after TBI. However, the effect of depression treatment on health care utilization has yet to be studied.

Objective

To examine whether an association exists between pharmacologic treatment of depression at the time of mild or concussive TBI and the number of subsequent clinician visits for persistent injury-related symptoms.

Design

Retrospective medical record review.

Setting

Tertiary care medical center.

Participants

A total of 120 patients (mean age 45.6 years) with a history of depression who subsequently experienced a mild or concussive TBI were included.

Methods

Individuals were identified with co-occurring diagnoses of depression and mild or concussive TBI by retrospective electronic medical record review. The diagnosis of depression must have preceded the diagnosis of TBI.

Main Outcome

The number of clinician visits for postinjury symptoms were counted at 3, 6, and 12 months postinjury.

Results

Clinician visits for persistent injury-related symptoms were significantly fewer at all 3 time points for the group treated for depression at time of injury.

Conclusions

Depressed individuals who were pharmacologically treated for depression at the time of TBI had significantly fewer clinician visits for persistent postinjury symptoms than those not pharmacologically treated for depression at the time of injury. Routine depression screening in patients with a high risk for TBI may identify a mood disorder that could contribute to persistent symptoms if left untreated, with its effective management potentially reducing health-related costs.

Objective

To prospectively compare the proportion of traumatic brain injuries (TBIs) that would be classified as mild by applying different published definitions of mild TBI to a large prospectively collected dataset, and to examine the variability in the proportions included by various definitions.

Design

Prospective observational study.

Setting

Hospital emergency departments.

Participants

Children (N=11,907) aged 3 to 16 years (mean age, 8.2±3.9y). Of the participants, 3868 (32.5%) were girls, and 7374 (61.9%) of the TBIs were the result of a fall. Median Glasgow Coma Scale score was 15.

Main Outcome Measures

We applied 17 different definitions of mild TBI, identified through a published systematic review, to children aged 3 to 16 years. Adjustments and clarifications were made to some definitions. The number and percentage identified for each definition is presented.

Results

Adjustments had to be made to the 17 definitions to apply to the dataset: none in 7, minor to substantial in 10. The percentage classified as mild TBI across definitions varied from 7.1% (n=841) to 98.7% (n=11,756) and varied by age group.

Conclusions

When applying the 17 definitions of mild TBI to a large prospective multicenter dataset of TBI, there was wide variability in the number of cases classified. Clinicians and researchers need to be aware of this variability when examining literature concerning children with mild TBI.  相似文献

Clinical practice guidelines admonish against prescribing opioids for individuals with chronic pain and traumatic brain injury (TBI) because of increased risk for adverse outcomes, yet no studies have described opioid prescribing patterns in these higher-risk patients. Between October 2007 and March 2015, 53,124 Iraq and Afghanistan veterans with chronic pain not prescribed opioids in the previous year were followed for 1 year after completing a Comprehensive TBI Evaluation within the Department of Veterans Affairs health care facilities. Veterans reporting the most severe TBI sequelae (eg, loss of consciousness?>30 minutes) were significantly more likely to receive short-term and long-term opioid therapy than those with less severe or no TBI sequelae (P values?<?.001). In analyses adjusted for sociodemographic characteristics, military service, pain disability, and previous nonopioid treatment modalities, veterans with moderate to severe TBI had a significantly increased risk of receiving opioid therapy. Veterans with moderate to severe TBI and comorbid post-traumatic stress disorder and depression had an even greater risk of initiating long-term opioid therapy in the year after the Comprehensive TBI Evaluation (adjusted relative risk?=?3.57 [95% confidence interval?=?2.85–4.47]). Higher-risk patients with chronic pain and TBI with mental health comorbidities may benefit from improved access to behavioral health and nonpharmacological therapies for chronic pain.

Perspective

Paradoxically, veterans with greater TBI severity and comorbid mental health burden are more likely to be prescribed opioids for chronic pain. More vulnerable veterans may benefit from improved access to behavioral health and nonpharmacological modalities for chronic pain, because of the health and safety risks of opioids.  相似文献

Objectives

To investigate the role of spinal cord injury (SCI) peer mentorship on quality of life (QoL)/participation, and test a self-determination theory model that explains the role of SCI peer mentorship on these outcomes.

Design

A static group comparison design.

Setting

Community.

Participants

A convenience sample of mentees (individuals receiving peer mentorship) (n=68) and nonmentees (n=63) who had an SCI, were older than 18 years, and spoke either English or French.

Interventions

Mentees: at least 4 peer mentorship sessions over the past 5 years; nonpeer mentees: 0 or 1 brief introductory session.

Main Outcome Measures

QoL (ie, life satisfaction and positive and negative affect), participation (eg, autonomous indoor; family role), and the psychological needs of autonomy, competence, and relatedness.

Results

No group differences were found, but years since injury was a moderator indicating that, generally, peer mentees living with SCI for longer (~30y) appear to benefit more from peer mentorship interactions compared with nonmentees and mentees living with SCI for approximately 6 years. Competence and relatedness mediated the peer mentorship–outcome relationship for QoL and some participation variables, indicating that peer mentorship predicted competence and relatedness, which in turn were related to the outcomes.

Conclusions

Satisfaction of competence and relatedness needs requires greater attention in SCI peer mentorship. Years since injury modified the relationship between peer mentorship and outcomes, which provided new insights on the role of SCI peer mentorship. Further studies are needed to determine SCI peer mentorship–specific outcomes that are important across the years-since-injury spectrum.  相似文献

Objective

To explore the factor structure of the UK Functional Independence Measure and Functional Assessment Measure (FIM+FAM) among focal and diffuse acquired brain injury patients.

Design

Criterion standard.

Setting

A National Health Service acute acquired brain injury inpatient rehabilitation hospital.

Participants

Referred sample of adults (N=447) admitted for inpatient treatment following an acquired brain injury significant enough to justify intensive inpatient neurorehabilitation

Intervention

Not applicable.

Outcome Measure

Functional Independence Measure and Functional Assessment Measure.

Results

Exploratory factor analysis suggested a 2-factor structure to FIM+FAM scores, among both focal-proximate and diffuse-proximate acquired brain injury aetiologies. Confirmatory factor analysis suggested a 3-factor bifactor structure presented the best fit of the FIM+FAM score data across both aetiologies. However, across both analyses, a convergence was found towards a general factor, demonstrated by high correlations between factors in the exploratory factor analysis, and by a general factor explaining the majority of the variance in scores on confirmatory factor analysis.

Conclusions

Our findings suggested that although factors describing specific functional domains can be derived from FIM+FAM item scores, there is a convergence towards a single factor describing overall functioning. This single factor informs the specific group factors (eg, motor, psychosocial, and communication function) after brain injury. Further research into the comparative value of the general and group factors as evaluative/prognostic measures is indicated.  相似文献

Objective

To determine the relation between sleep quantity and sleep disturbances on symptoms and neurocognitive ability during the acute phase (<7d) and after sports-related concussion (SRC; >21d).

Design

Prospective inception cohort study.

Setting

General community setting of regional middle and high schools.

Participants

A sample (N=971) including youth athletes with SRC (n=528) and controls (n=443) (age, 10–18y).

Interventions

Not applicable.

Main Outcome Measures

Athletes completed the Immediate Post-Concussion Assessment and Cognitive Testing battery. Partial correlation analyses and independent t tests were conducted to assess sleep quantity the night before testing. Multivariate analysis of covariance was used to assess sleep disturbances and their interaction with age.

Results

Less sleep quantity was correlated with greater report of cognitive (P=.001) and neuropsychological (P=.024) symptoms specific to prolonged recovery from SRC. Sleep disturbances significantly affect each migraine, cognitive, and neuropsychological symptoms (P<.001). A significant interaction was found between sleep disturbances and age (P=.04) at >21 days post-SRC.

Conclusions

Findings emphasize that the continued presence of low sleep quantity and sleep disturbances in youth athletes with SRC should be a specific indicator to health professionals that these athletes are at an increased risk of protracted recovery. Further research should identify additional factors that may interact with sleep to increase the risk of protracted recovery.  相似文献
