The influence of neuropsychological rehabilitation on symptomatology and quality of life following brain injury: A controlled long-term follow-up

Young Adults With Acquired Brain Injury Show Longitudinal Improvements in Cognition After Intensive Cognitive Rehabilitation

PURPOSE

The aim of this study was to assess the effect of an intensive cognitive and communication rehabilitation (ICCR) program on language and other cognitive performance in young adults with acquired brain injury (ABI).

METHOD

Thirty young adults with chronic ABI participated in this study. Treatment participants (n = 22) attended ICCR 6 hours/day, 4 days/week for at least one 12-week semester. Deferred treatment/usual care control participants (n = 14) were evaluated before and after at least one 12-week semester. Pre- and postsemester standardized cognitive assessment items were assigned to subdomains. Between-groups and within-group generalized linear mixed-effects models assessed the effect of time point on overall item accuracy and differences by item subdomain. Subdomain analyses were adjusted for multiple comparisons.

RESULTS

Between-groups analyses revealed that treatment participants improved significantly faster over time than deferred treatment/usual care participants in overall item accuracy and specifically on items in the verbal expression subdomain. Investigating the three-way interaction between time point, group, and etiology revealed that the overall effects of the treatment were similar for individuals with nontraumatic and traumatic brain injuries. The treatment group showed an overall effect of treatment and significant gains over time in the verbal expression, written expression, memory, and problem solving subdomains. The control group did not significantly improve over time on overall item accuracy and showed significant subdomain-level gains in auditory comprehension, which did not survive correction.

CONCLUSIONS

Sustaining an ABI in young adulthood can significantly disrupt key developmental milestones, such as attending college and launching a career. This study provides strong evidence that integrating impairment-based retraining of language and other cognitive skills with "real-world" application in academically focused activities promotes gains in underlying cognitive processes that are important for academic success as measured by standardized assessment items. These findings may prompt a revision to the current continuum of rehabilitative care for young adults with ABI.

Multi-level outcomes for young adults with acquired brain injury through a remote intensive cognitive rehabilitation approach: a pilot intervention study

OBJECTIVE

To investigate the effects of the Intensive Cognitive and Communication Rehabilitation (ICCR) program for young adults with acquired brain injury (ABI) using a quasi-experimental pilot intervention study design while transitioning to remote implementation.

METHOD

Twelve young adults with chronic ABI (treatment n = 7; control n = 5) participated in ICCR (i.e., lectures, seminars, individual cognitive rehabilitation (CR), technology training) for six hours/day, four days/week, for one or two 12-week semesters. Outcomes included classroom metrics, individual therapy performance, including Goal Attainment Scaling (GAS), standardized cognitive-linguistic assessments, and participation and health-related quality of life (QOL) measures.

RESULTS

In the first semester (in-person and remote), treatment participants significantly improved in classroom exams; individual therapy (i.e., memory, writing, GAS); executive function and participation measures, but not QOL. In the second semester (remote), treatment participants significantly improved in classroom exams; essay writing; individual therapy (i.e., writing and GAS); and memory assessment, but not in participation or QOL. Treatment participants enrolled in consecutive semesters significantly improved in classroom exams, individual therapy (i.e., memory), participation and QOL, but not on standardized cognitive assessments. Controls demonstrated no significant group-level gains.

CONCLUSION

These preliminary results highlight the benefit of intensive, integrated, and contextualized CR for this population and show promise for its remote delivery.

Development of prognostic models for Health-Related Quality of Life following traumatic brain injury

Background

Traumatic brain injury (TBI) is a leading cause of impairments affecting Health-Related Quality of Life (HRQoL). We aimed to identify predictors of and develop prognostic models for HRQoL following TBI.

Methods

We used data from the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) Core study, including patients with a clinical diagnosis of TBI and an indication for computed tomography presenting within 24 h of injury. The primary outcome measures were the SF-36v2 physical (PCS) and mental (MCS) health component summary scores and the Quality of Life after Traumatic Brain Injury (QOLIBRI) total score 6 months post injury. We considered 16 patient and injury characteristics in linear regression analyses. Model performance was expressed as proportion of variance explained (R²) and corrected for optimism with bootstrap procedures.

Results

2666 Adult patients completed the HRQoL questionnaires. Most were mild TBI patients (74%). The strongest predictors for PCS were Glasgow Coma Scale, major extracranial injury, and pre-injury health status, while MCS and QOLIBRI were mainly related to pre-injury mental health problems, level of education, and type of employment. R² of the full models was 19% for PCS, 9% for MCS, and 13% for the QOLIBRI. In a subset of patients following predominantly mild TBI (N = 436), including 2 week HRQoL assessment improved model performance substantially (R² PCS 15% to 37%, MCS 12% to 36%, and QOLIBRI 10% to 48%).

Conclusion

Medical and injury-related characteristics are of greatest importance for the prediction of PCS, whereas patient-related characteristics are more important for the prediction of MCS and the QOLIBRI following TBI.

Cognitive Retraining in Traumatic Brain Injury: Experience from Tertiary Care Center in Southern India

Objective  Traumatic brain injury (TBI) is a leading cause of mortality and chronic disability across the globe. This study aimed to understand the effects of cognitive retraining (CR) intervention on neuropsychological functions, symptom reporting, and quality of life in patients with moderate to severe TBI.

Materials and Methods  The present single-group intervention study with a pre–post design included 12 patients diagnosed with moderate to severe TBI within 3–24 months post injury. Outcome measures included National Institute of Mental Health and Neuro Sciences (NIMHANS) Neuropsychology Battery, Perceived Stress Scale, Rivermead Post-Concussion Symptom Questionnaire, World Health Organization Quality of Life Scale—Brief, and Visual Analogue Scale. All patients underwent a total of 20 sessions of hospital-based CR, spanning over a period of 2 months. The CR included tasks targeting to enhance processing speed, attention, executive function, learning, and memory. Outcome assessments were conducted at baseline and immediately at post intervention.

Statistical Analysis  Mean, standard deviation, frequency, and percentage were used as measures of descriptive statistics. Pre- and post-intervention scores were compared using Wilcoxon signed-rank test.

Results  The results showed that at post intervention, significant improvements were found in processing speed, working memory, planning, visuo-spatial construction, visual memory, and verbal encoding. Subjective symptom reporting, perceived stress, and quality of life in psychological domain also improved.

Conclusion  CR can be helpful in improving not only cognition but also symptom reporting and quality of life in moderate to severe TBI.

The Role of Self-Efficacy in the Recovery Process of Stroke Survivors

Introduction

Belief in one’s personal capabilities are conducive to achieving success and provides additional energy for action. The stronger the conviction of one’s self-efficacy, the higher the self-goals and the stronger the commitment to achieving them, despite any adversities. Our knowledge regarding the role of self-efficacy in post-stroke rehabilitation is still scarce.

Aim of the Study

The study aimed to analyze characteristics related to high self-efficacy levels before and after rehabilitation and to determine the role of self-efficacy in this process.

Materials and Methods

The study involved 99 stroke survivors. Participants’ mental and functional state were assessed using Generalized Self-Efficacy Scale (GSES), Barthel Index (BI), Acceptance of Illness Scale (AIS), Geriatric Depression Scale (GDS), Visual Analogue Scale for Pain (VAS), Instrumental Activities of Daily Living (IADL) and Rivermead Mobility Index (RMI). Patients were evaluated twice: on admission (T₁) and 3 weeks into rehabilitation (T₂).

Results

Patients without self-efficacy improvement after 3 weeks of rehabilitation, on discharge from the ward demonstrated poorer well-being (p = 0.002, Hedges’ g = 0.63, 95% CI [0.24–1.08]), lower illness acceptance levels (p < 0.001, Hedges’ g = −0.78, 95% CI [−1.25 – −0.41]), poorer functional status in basic activities of daily living (p = 0.003, Hedges’ g = −0.62, 95% CI [−1 – −0.25]), locomotive abilities (p = 0.004, Hedges’ g = −0.58, 95% CI [−1.12 – −0.15]) and instrumental activities of daily living (p = 0.001, Hedges’ g = −0.71, 95% CI [−1.15 – −0.34]).

Conclusion

Self-efficacy level is significantly related to rehabilitation outcomes. A routine self-efficacy assessment during the rehabilitation process seems very important. Patients whose initial self-efficacy is low or remains unchanged despite rehabilitation require special attention. Close cooperation between all members of the therapeutic team is essential to strengthen, at each stage, the sense of self-efficacy in stroke survivors.

Cognitive function and health-related quality of life 1 year after acute brain injury: An observational study

BACKGROUND

Cognitive impairment and reduced health-related quality of life (HRQoL) are well-established sequelae of critical illness. Studies on survivors of critical illness have found delirium to be a predictor of these conditions, but evidence regarding survivors of acute brain injury is sparse. We aimed to explore if delirium duration was associated with 1-year cognitive impairment and reduced HRQoL in patients with acute brain injury.

METHOD

Intensive care unit (ICU) delirium was assessed using the Intensive Care Delirium Screening Checklist. Cognitive status was assessed using the Repeatable Battery for Neuropsychological Status (RBANS) and HRQoL using the European Quality of Life 5-dimension questionnaire (EQ-5D). We used a multiple linear regression for testing the association of delirium duration with cognitive impairment and quality of life, respectively.

RESULTS

Forty-seven survivors of acute brain injury participated in follow-up and 35 completed RBANS. Delirium was present in 39 of 47 (83%) with a median duration of 4 days. Delirium duration did not predict cognitive impairment (95% CI -4.1 to 0.5) or lower HRQoL (95% CI -1.4 to 2.7). Moderate-to-severe cognitive impairment was present in 17 of 35 (49%) participants, and they had a mean EQ-5D health visual analogue scale of 70.9 vs 81.6 for the Danish age-matched norm.

CONCLUSIONS

Our sample did not demonstrate an association between delirium and 1-year cognitive impairment or reduced HRQoL. Still, a large proportion of the participants were cognitively impaired, and their quality of life was lower compared to norm. Larger studies are necessary to explore these associations further.

Early, specialist vocational rehabilitation to facilitate return to work after traumatic brain injury: the FRESH feasibility RCT

BACKGROUND

Up to 160,000 people incur traumatic brain injury (TBI) each year in the UK. TBI can have profound effects on many areas of human functioning, including participation in work. There is limited evidence of the clinical effectiveness and cost-effectiveness of vocational rehabilitation (VR) after injury to promote early return to work (RTW) following TBI.

OBJECTIVE

To assess the feasibility of a definitive, multicentre, randomised controlled trial (RCT) of the clinical effectiveness and cost-effectiveness of early, specialist VR plus usual care (UC) compared with UC alone on work retention 12 months post TBI.

DESIGN

A multicentre, feasibility, parallel-group RCT with a feasibility economic evaluation and an embedded mixed-methods process evaluation. Randomisation was by remote computer-generated allocation.

SETTING

Three NHS major trauma centres (MTCs) in England.

PARTICIPANTS

Adults with TBI admitted for > 48 hours and working or studying prior to injury.

INTERVENTIONS

Early specialist TBI VR delivered by occupational therapists (OTs) in the community using a case co-ordination model.

MAIN OUTCOME MEASURES

Self-reported RTW 12 months post randomisation, mood, functional ability, participation, work self-efficacy, quality of life and work ability. Feasibility outcomes included recruitment and retention rates. Follow-up was by postal questionnaires in two centres and face to face in one centre. Those collecting data were blind to treatment allocation.

RESULTS

Out of 102 target participants, 78 were recruited (39 randomised to each arm), representing 39% of those eligible and 5% of those screened. Approximately 2.2 patients were recruited per site per month. Of those, 56% had mild injuries, 18% had moderate injuries and 26% had severe injuries. A total of 32 out of 45 nominated carers were recruited. A total of 52 out of 78 (67%) TBI participants responded at 12 months (UC, n = 23; intervention, n = 29), completing 90% of the work questions; 21 out of 23 (91%) UC respondents and 20 out of 29 (69%) intervention participants returned to work at 12 months. Two participants disengaged from the intervention. Face-to-face follow-up was no more effective than postal follow-up. RTW was most strongly related to social participation and work self-efficacy. It is feasible to assess the cost-effectiveness of VR. Intervention was delivered as intended and valued by participants. Factors likely to affect a definitive trial include deploying experienced OTs, no clear TBI definition or TBI registers, and repatriation of more severe TBI from MTCs, affecting recruitment of those most likely to benefit/least likely to drop out.

LIMITATIONS

Target recruitment was not reached, but mechanisms to achieve this in future studies were identified. Retention was lower than expected, particularly in UC, potentially biasing estimates of the 12-month RTW rate.

CONCLUSIONS

This study met most feasibility objectives. The intervention was delivered with high fidelity. When objectives were not met, strategies to ensure feasibility of a full trial were identified. Future work should test two-stage recruitment and include resources to recruit from 'spokes'. A broader measure covering work ability, self-efficacy and participation may be a more sensitive outcome.

General self-efficacy as a driving factor of post-stroke depression: A longitudinal study

Post-stroke depression (PSD) is the most common psychiatric condition after stroke, affecting one third of survivors. Despite identification of meaningful predictors, knowledge about the interplay between these factors remains fragmentary. General self-efficacy (GSE) is closely linked to PSD, yet direction and magnitude of this relationship remains unclear. The authors assessed the relationship between GSE and depression during the first two years post-stroke while controlling for stable inter-individual differences using continuous time (CT) structural equation modelling (SEM). Patients of two German rehabilitation centres (N = 294, mean age = 63.78 years, SD = 10.83) were assessed six weeks after ischemic stroke and at four follow-ups covering two years. GSE Scale and Geriatric Depression Scale (GDS) were used to assess GSE and depression. CT-analysis revealed significantly higher within-person cross-effects of GSE on GDS (a₂₁ = -.29) than vice versa (a₁₂= -.17). Maximal cross-lagged effects emerged six months post-stroke. Our results show that decreasing GSE led to increasing depressiveness, and only to a smaller extent vice versa. This suggests that fostering GSE by strengthening perceived control after stroke can counter PSD emersion and exacerbation. Six months post-stroke, when patients face social re-integration, programmes focusing on GSE could potentially help to prevent later PSD.

Outcomes of a community-based treatment programme for people with acquired brain injury in the chronic phase: a pilot study

The objective of the study was to evaluate the outcomes of Brainz, a low intensity community-based treatment programme for people with acquired brain injury (ABI). Participants were 62 people with sustained ABI (5.2 years post-injury, SD = 4.5) and 35 family caregivers. Participants attended two to five cognitive and physical group modules and received two hours of individual home treatment every two weeks. Primary outcomes for people with ABI were participation, perceived difficulties in daily life and need of care, level of goal attainment, and self-esteem. Primary family caregiver outcome was perceived burden of care. Attrition rate of people with ABI was 24% (n = 15), and of family caregivers was 31% (n = 11). People with ABI were more satisfied with the level of their participation after completing Brainz (p < .01), but showed no change in participation frequency or in restrictions (both ps > .01). They perceived fewer difficulties in daily life and less need of care (both ps < .01). Also, in two cognitive modules people improved on their goal achievement (p < .01). However, their self-esteem was reduced (p < .01). Caregiver burden was reduced (p < .01). This study has provided preliminary evidence of the effectiveness of a combined group-based clinical and individual home-based treatment programme, but more research is needed, preferably in larger controlled studies.

The Norwegian version of the QOLIBRI - a study of metric properties based on a 12 month follow-up of persons with traumatic brain injury

BACKGROUND

Consequences after Traumatic brain injury (TBI) affect the injured person's self-image and quality of life. The purpose was to assess the health related quality of life (HRQoL) at 12 months after a TBI in patients admitted to regional trauma centres, and to evaluate the metric properties of the Norwegian version of the Quality of Life After Brain Injury (QOLIBRI) questionnaire.

METHODS

Two hundred four patients with TBI of all severities were included. HRQoL at 12 months post-injury was measured by the QOLIBRI. It has a total scale and 6 subscales (satisfied with Cognition, Self, Daily Life and Autonomy and Social Relationships, and bothered by Emotions and Physical Problems). Demographic and injury related data were registered. Disability was registered by Glasgow Outcome Scale Extended (GOSE) and Rivermead Post-Concussion Questionnaire, and mental health by Hospital Anxiety and Depression Scale. Descriptive statistics, internal consistency by Cronbach's alpha and Corrected Item-Total Correlations were calculated. Rasch analysis, Principal Component Analysis (PCA) and Structural Equation Modelling (SEM) were applied.

RESULTS

Mean age was 37.6 (SD 15.4) years; 72% were men, and 41% had higher education. Over 60% were severely injured. Mean Glasgow Coma Scale score was 9.3 (SD 4.5). According to the GOSE 5.9% had severe disability, 45.5% had moderate disability, and 48.5% had good recovery at 12 months post-injury. The QOLIBRI scales had a high internal consistency (α = 0.75-0.96), and only Physical Problems had an α < 0.85. In the Rasch analysis all subscales and their items fit the Rasch model, except for the depression item in the Emotion subscale. PCA and SEM analyses supported a six-factor structure in a second-order latent model. The QOLIBRI supports an underlying unidimensional HRQoL model. The SEM model fit statistics of the second-order model indicated a moderate fit to the observed data (CFI = 0.86, TLI = 0.85, RMSEA = 0.076, SRMR = 0.061, χ2 = 1315.76, df = 623, p-value < 0.001).

CONCLUSION

The Norwegian QOLIBRI has favourable psychometric properties, but there were some weaknesses related to its measurement properties of the total score when tested on a TBI population where many had severe TBI, and many had good recovery.

Evaluation of a Cognitive Rehabilitation Protocol in HIV Patients with Associated Neurocognitive Disorders: Efficacy and Stability Over Time

The primary aim of the present study was to evaluate the efficacy and stability over time of a cognitive rehabilitation protocol (restorative and compensatory approach) in HIV/AIDS patients with HIV-associated Neurocognitive Disorder (HAND). At baseline, 32 HIV/AIDS patients (16 with and 16 without HAND) were assessed with a neuropsychological battery (i.e., pre-assessment) consisting of 22 tests covering eight cognitive domains. Then, the experimental group was administered over 4 months a cognitive rehabilitation protocol aimed at improving four cognitive domains by means of eight paper and pencil/computer-based exercises. The control group received guideline-adherent clinical care (i.e., standard of care). At the end of the cognitive treatment, both groups were re-administered the neuropsychological battery (i.e., post-assessment). Additionally, 6 months after post-assessment, the experimental group was given the same neuropsychological battery (i.e., follow up-assessment). In order to test the efficacy of the cognitive rehabilitation protocol, we compared between groups the results of the neuropsychological battery at the pre- and post-assessments. In order to evaluate the stability over time, the effects of the cognitive rehabilitation protocol was examined comparing within the experimental group the results of the neuropsychological battery at post- and follow up-assessments. Our results show that the two groups did not differ at the pre-assessment, but differed at post-assessment. Specifically, the experimental group showed a significant improvement in five domains (Learning and memory, Abstraction/executive functioning, Verbal fluency, Attention/working memory, and Functional), whereas the control group significantly worsened in the same domains. The improvement of the experimental group did not change in the follow up-assessment in two domains (Abstraction/executive functioning, Attention/working memory, and Functional). Overall, these findings support the efficacy and, to some extent, the stability over time of our cognitive rehabilitation protocol.

Health-related quality of life after TBI: a systematic review of study design, instruments, measurement properties, and outcome

Measurement of health-related quality of life (HRQL) is essential to quantify the subjective burden of traumatic brain injury (TBI) in survivors. We performed a systematic review of HRQL studies in TBI to evaluate study design, instruments used, methodological quality, and outcome. Fifty-eight studies were included, showing large variation in HRQL instruments and assessment time points used. The Short Form-36 (SF-36) was most frequently used. A high prevalence of health problems during and after the first year of TBI was a common finding of the studies included. In the long term, patients with a TBI still showed large deficits from full recovery compared to population norms. Positive results for internal consistency and interpretability of the SF-36 were reported in validity studies. The Quality of Life after Brain Injury instrument (QOLIBRI), European Brain Injury Questionnaire (EBIQ), Child Health Questionnaire (CHQ), and the World Health Organization Quality of Life short version (WHOQOL-BREF) showed positive results, but evidence was limited. Meta-analysis of SF-36 showed that TBI outcome is heterogeneous, encompassing a broad spectrum of HRQL, with most problems reported in the physical, emotional, and social functioning domain. The use of SF-36 in combination with a TBI-specific instrument, i.e., QOLIBRI, seems promising. Consensus on preferred methodologies of HRQL measurement in TBI would facilitate comparability across studies, resulting in improved insights in recovery patterns and better estimates of the burden of TBI.

Relationships between kinesiotherapy methods used in rehabilitation and the course of lost function recovery following surgical treatment of cranio-cerebral trauma

INTRODUCTION AND AIM

This paper aims to outline the relationships between kinesiotherapy methods used in rehabilitation and the recovery of the patient's ability to perform activities of daily living (ADLs), improvement of functional condition, regression of pareses and improvement of conscious state following surgical treatment of traumatic subdural haematomas.

MATERIALS AND METHODS

The study was conducted on 84 patients treated surgically for traumatic subdural haematomas, divided into two groups. The key differentiating factor was the kinesiotherapy method used in rehabilitation. Patients were assessed using the International Scale of Muscle Weakness (ISMW), Barthel Index and modified Rankin Scale, while their conscious state was assessed using the Glasgow Coma Scale.

RESULTS

A significant improvement of the assessed features was observed in all patients. However, patients treated with proprioceptive neuromuscular facilitation (PNF) and elements of the Bobath concept regained lost function significantly faster than patients treated with traditional kinesiotherapy. No significant differences were observed in the course of improvement of conscious state between the two groups.

CONCLUSIONS

Treatment using functional elements may significantly accelerate the return of the ability to perform ADLs, improvement in functional condition and regression of pareses in comparison with traditional kinesiotherapy.

Spanish, French, and British cross-cultural validation of the European Brain Injury Questionnaire

OBJECTIVE

To explore the factor structure of the European Brain Injury Questionnaire and to assess the cross-cultural and construct validity of this questionnaire by using Rasch analysis.

PARTICIPANTS

A total of 366 individuals with traumatic brain injury or stroke were recruited from 3 different countries: Spain (116 participants), the United Kingdom (110 participants), and France (140 participants).

ANALYSES

We first performed a factor analysis and then applied Rasch analysis to the resulting factors to examine construct and cross-cultural validity.

RESULTS

Three subscales labeled Depressive Mood, Cognitive Dysfunction, and Poor Social and Emotional Self-regulation were extracted using the factor analysis. In the Rasch analyses, 8 items were removed because of misfit and 7 items showed differential item functioning by country.

CONCLUSION

Rasch analyses showed good fit to the model, unidimensionality, construct validity, and good reliability of the 3 European Brain Injury Questionnaire subscales. However, only the Depressive and Cognitive subscales showed cross-cultural validity.

Evidence-based cognitive rehabilitation: updated review of the literature from 2003 through 2008

OBJECTIVE

To update our clinical recommendations for cognitive rehabilitation of people with traumatic brain injury (TBI) and stroke, based on a systematic review of the literature from 2003 through 2008.

DATA SOURCES

PubMed and Infotrieve literature searches were conducted using the terms attention, awareness, cognitive, communication, executive, language, memory, perception, problem solving, and/or reasoning combined with each of the following terms: rehabilitation, remediation, and training for articles published between 2003 and 2008. The task force initially identified citations for 198 published articles.

STUDY SELECTION

One hundred forty-one articles were selected for inclusion after our initial screening. Twenty-nine studies were excluded after further detailed review. Excluded articles included 4 descriptive studies without data, 6 nontreatment studies, 7 experimental manipulations, 6 reviews, 1 single case study not related to TBI or stroke, 2 articles where the intervention was provided to caretakers, 1 article redacted by the journal, and 2 reanalyses of prior publications. We fully reviewed and evaluated 112 studies.

DATA EXTRACTION

Articles were assigned to 1 of 6 categories reflecting the primary area of intervention: attention; vision and visuospatial functioning; language and communication skills; memory; executive functioning, problem solving and awareness; and comprehensive-holistic cognitive rehabilitation. Articles were abstracted and levels of evidence determined using specific criteria.

DATA SYNTHESIS

Of the 112 studies, 14 were rated as class I, 5 as class Ia, 11 as class II, and 82 as class III. Evidence within each area of intervention was synthesized and recommendations for Practice Standards, Practice Guidelines, and Practice Options were made.

CONCLUSIONS

There is substantial evidence to support interventions for attention, memory, social communication skills, executive function, and for comprehensive-holistic neuropsychologic rehabilitation after TBI. Evidence supports visuospatial rehabilitation after right hemisphere stroke, and interventions for aphasia and apraxia after left hemisphere stroke. Together with our prior reviews, we have evaluated a total of 370 interventions, including 65 class I or Ia studies. There is now sufficient information to support evidence-based protocols and implement empirically-supported treatments for cognitive disability after TBI and stroke.

Quality of life after traumatic brain injury: the clinical use of the QOLIBRI, a novel disease-specific instrument

OBJECTIVE

To report the clinical use of the QOLIBRI, a disease-specific measure of health-related quality-of-life (HRQoL) after traumatic brain injury (TBI).

METHODS

The QOLIBRI, with 37 items in six scales (cognition, self, daily life and autonomy, social relationships, emotions and physical problems) was completed by 795 patients in six languages (Finnish, German, Italian, French, English and Dutch). QOLIBRI scores were examined by variables likely to be influenced by rehabilitation interventions and included socio-demographic, functional outcome, health status and mental health variables.

RESULTS

The QOLIBRI was self-completed by 73% of participants and 27% completed it in interview. It was sensitive to areas of life amenable to intervention, such as accommodation, work participation, health status (including mental health) and functional outcome.

CONCLUSION

The QOLIBRI provides information about patient's subjective perception of his/her HRQoL which supplements clinical measures and measures of functional outcome. It can be applied across different populations and cultures. It allows the identification of personal needs, the prioritization of therapeutic goals and the evaluation of individual progress. It may also be useful in clinical trials and in longitudinal studies of TBI recovery.

The return to work after a neuropsychological programme and prognostic factors for success

INTRODUCTION

Several factors influence the return to work (RTW) after brain injury (BI). The aims of the study were to follow-up the RTW after a vocational neuropsychological programme for individuals with a brain injury and to explore factors predicting RTW. The hypothesis was that as self-awareness was already addressed in the programme, severity of injury would have a greater impact on RTW.

METHOD

Sixty-five of 72 persons (median age 27) who had attended the programme 1998-2003 were interviewed about their occupation at 1, 2, 3 and 5 years after the programme. A logistic regression was made with the variables concerning process skill, somatic problems and irritability, the digit symbol coding and pre-morbid occupation to explore predictors of RTW.

RESULTS

The main cause was TBI (44.6%). Before injury 77% were employed or studied and after the injury 80% did not have any occupation. After 5 years 40% had returned to work. The only significant variable in the regression was the pre-morbid occupation.

DISCUSSION

The study stresses the difficulty to know the key elements involved in RTW which confirms the need for rehabilitation to focus on several factors in different contexts in order to affect the outcome.

The truth effect in relation to neuropsychological functioning in traumatic brain injury

OBJECTIVES

Individuals with traumatic brain injury may have difficulty accepting other viewpoints, but there is not yet a clinical test to measure the readiness with which one accepts new information as true. This study examined the truth effect-the tendency to rate previously seen material as being 'more true' than newly presented material-to explore whether individual differences in the truth effect can be quantified and related to memory or other neuropsychological variables, including brain injury severity.

METHODS

Seventy-four individuals being seen for neuropsychological assessment were asked to classify 15 semantic statements as biographical, scientific or historical and were later asked to rate 10 of the previously viewed statements and 10 new statements as either true or false.

RESULTS

A truth effect was clearly present in two groups which had gained familiarity with opposite sets of statements. As well, individuals with better immediate verbal memories rated more of the previously seen statements as true.

CONCLUSIONS

A verbal encoding factor appears to underlie the truth effect and may explain the difficulties that some TBI patients have in accepting newly presented information as true.

Traumatic brain injury and long-term quality of life: findings from an Australian study

Recent calls have been made for the inclusion of health-related quality of life (HRQoL) in traumatic brain injury studies. This study reports the impact of TBI on traditional measures (general health, depression, social isolation, labor force participation), self-assessed health function status using the SF-36 version 2 (SF-36V2), and self-assessed health preference using two generic utility instruments, the assessment of quality of life (AQoL) and the SF6D. A random sample of TBI cases (n = 66) was drawn from a trauma registry and matched (gender, age, education, and relationship status) with non-trauma-exposed cases from a population health survey. All participants were interviewed and the two cohorts compared. When compared with matched comparators, TBI cases experienced worse general health, elevated probabilities of depression, social isolation, and worse labor force participation rates. The TBI-cohort reported worse health status on the SF-36V2. The most affected areas were social function, role emotion, and mental health (effect sizes -0.70 to -0.86). The reported utility values indicative of a HRQoL between 13 and 24% worse than their non-TBI contemporaries (effect sizes -0.80 to -0.81). The findings suggest that TBI has long-term consequences across all aspects of peoples' lives, and that these consequences can be self-assessed using generic instruments. The challenge is to provide and evaluate long-term services targeted at the life areas that those with TBI find particularly difficult.
