Cluster analysis of self-awareness levels in adults with traumatic brain injury and relationshipto outcome

Socratic guided feedback therapy after acquired brain injury: A multicenter randomized controlled trial to evaluate effects on self-awareness

Impaired self-awareness after acquired brain injury (ABI) challenges neuropsychological rehabilitation. The current study aimed to compare the effects of Socratic Guided Feedback therapy to usual care in a multicenter randomized controlled trial with 64 participants with reduced self-awareness after ABI. The objectives were to study the effects on (1) self-awareness and (2) motivation for and participation in therapy, mood, quality of life, and social participation. Patients were recruited from rehabilitation centres in The Netherlands and Belgium. They were 50.8 (±16) years old and 2.7 months (±1.8) post-injury at baseline. Session duration ranged from 20-60 minutes and the number of sessions ranged from 1 to 162 sessions. Self-awareness increased over time in both groups. Between 9 and 12 months after baseline measurement, self-awareness (Patient Competency Rating Scale discrepancy score between patient and significant other) improved in the experimental group and deteriorated in care as usual. No significant differences were found on secondary outcome measures. In conclusion, Socratic Guided Feedback therapy is as effective as care as usual but provides a structure for therapists. We recommend further investigation of the added value of Socratic Guided Feedback therapy in later follow-up measurements, group therapy settings, and on other outcome domains such as caregiver burden.

Ecological validity of the Meyers Neuropsychological Battery

Neuropsychologists are increasingly being asked to apply neuropsychological test results to real world functioning; however, neuropsychological tests are not usually constructed to do so, but instead are more concerned with diagnostic accuracy than with prediction of daily functioning. Using samples of 5,460 patients that did self-ratings and 2791 patients that had family ratings plus the Meyers Neuropsychological Battery (MNB), it was found that the family ratings were better predicted by neuropsychological test data than were self-ratings on the 38 item Patient Competency Rating Scale (PCRS). The R values for family ratings on the 36 regression equations ranged from .236 to .763. The results show that the ratings given patients by family members could be predicted by the neuropsychological test results. These findings can help the clinician to make broad statements regarding likely real-life functioning and also support the ecological validity of the tests that make up the MNB.

Anosognosia in moderate-to-severe traumatic brain injury: A review of prevalence, clinical correlates, and diversity considerations

METHOD

A comprehensive search of peer-reviewed articles was conducted from September to November 2020 using Google Scholar and PubMed databases. Key terms included "anosognosia," "self-awareness," "traumatic brain injury," and variants thereof. Our search was restricted to articles published in English within the last 25 years, although a few historical articles were included due to scientific merit. Articles were chosen based on methodological quality, inclusion of solely or predominantly msevTBI sample, and relevance to the current topic.

CONCLUSIONS

Anosognosia is a multifaceted and domain-specific construct that affects the majority of those with msevTBI. It is related to TBI severity, injuries in right-hemispheric and cortical midline regions, specific aspects of executive function, psychological function, and cultural factors. We offer pragmatic advice for clinicians working with this population and discuss implications for the field regarding "best practices" of anosognosia assessment and intervention.

Modification of the Patient Competency Rating Scale to Measure Anosodiaphoria after Severe Acquired Brain Injury: Preliminary Findings

OBJECTIVE

Impaired self-awareness (ISA) of altered functional capacities is a common sequelae of severe acquired brain injury that can severely hamper neuro-rehabilitation in this clinical population. ISA is frequently associated with anosodiaphoria and/or apathy. Although several scales are available to measure apathy, no tools have been published to specifically assess anosodiaphoria after acquired brain injury. In this paper, we reported an initial effort to develop an anosodiaphoria subscale in a commonly used measure of ISA, that is, the Patient Competency Rating scale-neurorehabilitation form (PCRS-NR).

METHOD

A sample of 46 participants with severe acquired brain injury completed a functional, ISA, apathy, and anosodiaphoria assessment. One informal caregiver of each patient participated in the study. Thus, we were able to obtain external data on his/her level of functional competencies, and self-awareness, which allowed separating patients with low self-awareness (LSA) from those with high self-awareness (HSA). Finally, the patients were compared with 44 healthy age-gender-years of formal education matched control participants (HCs).

RESULTS

Compared to both patients with HSA and HCs, patients with LSA demonstrated greater anosodiapvhoria and lower levels of functioning than both HSA patients and HCs. A stronger relationship emerged between ISA and anosodiaphoria rather than with apathy.

CONCLUSIONS

These initial findings provide support that PCRS scale can be adapted to measure anosodiaphoria as well as ISA. The findings reveal a stronger correlation between this measure of anosodiaphoria and ISA compared with the correlation of apathy to ISA. The present method for measuring anosodiaphoria takes into account the actual levels of patients' functioning.

Impaired self-awareness after traumatic brain injury: A systematic review. Part 2. Consequences and predictors of poor self-awareness

BACKGROUND

Impaired self-awareness (ISA) has frequently been found both frequent and deleterious in patients with moderate to severe traumatic brain injury (TBI).

OBJECTIVES

This is the second of a two-part systematic review on ISA after TBI, focusing on the consequences and predictors of ISA after TBI.

METHODS

Following the PRISMA guidelines, 95 articles meeting the inclusion criteria were included; 46 were specifically related to this second part of the review.

RESULTS

Among 16 studies that investigated the effect of ISA on outcome, most (n=13) found poor self-awareness associated with poor rehabilitation, functional, social and vocational outcome and with increased burden on relatives. Multiple factors have been found associated with increased frequency of ISA. ISA was found significantly related to injury severity in 8 of 10 studies, impaired executive functions in 12 of 15 studies, and poor social cognition in 3 studies, but paradoxically inverse associations were repeatedly found between self-awareness and emotional status (11 of 12 studies). Finally, although research in the field is still scarce, ISA seems associated with a dysfunction within brain networks involving the anterior cingulate cortex, anterior insula and fronto-parietal control network.

CONCLUSIONS

ISA is a complex and multifaceted disorder associated with poor rehabilitation outcome, severe injuries, and deficits of executive functions and social cognition but has an inverse association with mood impairments.

Impaired self-awareness after traumatic brain injury: a systematic review. Part 1: Assessment, clinical aspects and recovery

BACKGROUND

Impaired self-awareness (ISA) has frequently been found to be both frequent and deleterious in patients with moderate to severe traumatic brain injury (TBI).

OBJECTIVES

The present paper is the first of a two-part systematic review of ISA after traumatic brain injury (TBI), focusing on assessment methods, clinical aspects and recovery.

METHODS

Following the PRISMA guidelines, 95 articles meeting the inclusion criteria were included.

RESULTS

ISA occurs in 30% to 50% of patients with moderate to severe TBI, although it tends to improve with time. There is no one single gold-standard measure of ISA. Self-proxy discrepancy scores, with scales such as the Patient Competency Rating Scale or the Awareness Questionnaire, or a structured interview such as the Self Awareness of Deficits Interview, are the most frequently used assessment methods, with adequate psychometric properties. Scores on these different scales correlate only moderately with each other, which suggests that they may address different aspects of self-awareness. ISA mainly concerns cognitive and behavioral problems rather than physical or sensory impairments and may concern different areas of functioning, such as anticipatory, emergent or meta-cognitive awareness.

CONCLUSION

ISA is a complex and multifaceted issue that should be systematically assessed in rehabilitation settings using a range of relatively well-validated tools. The consequences and predictors of ISA after TBI will be addressed in a companion paper.

Conceptualization of self-awareness in adults with acquired brain injury: A qualitative systematic review

Self-awareness is an important consideration in cognitive rehabilitation for clinicians working with individuals following acquired brain injury (ABI), with impaired self-awareness linked to poor outcomes. To appropriately target assessment and intervention for self-awareness, its theoretical foundation and definition must be considered. The aim was to identify the definitions, theoretical models and conceptual frameworks of self-awareness in adults with ABI, and how self-awareness is conceptualized within those models. A qualitative systematic review was completed using search terms related to descriptions of models/frameworks, ABI and self-awareness. Data were analysed by narrative synthesis. Thirty-five papers were included in the review. Within these, 13 models, 12 conceptual frameworks and 2 theories were described. The main themes and subthemes conceptualized in the synthesis were: Clinical presentation of self-awareness (classifications and dimensions of self-awareness), development of self-awareness (knowledge, feedback mechanisms, temporal aspects, self-evaluation, enablers, barriers), understanding (dys)function (cognitive processing mechanisms, neurological foundations, causal factors), and practice guidance (assessment and intervention). This review identified an extensive theoretical basis to support conceptualization of self-awareness following ABI, underpinned by a distinction between intellectual awareness, on-line awareness, and psychological denial. Clinical application of an evaluation process that includes these elements would be beneficial to inform the rehabilitation process.

Joint Video Self-Modeling for Persons With Traumatic Brain Injury and Their Partners: A Case Series

Purpose Individuals with traumatic brain injury (TBI) experience impairments to self-regulation and social communication that strain relationships. Video self-modeling (VSM) provides visible and audible, tangible evidence of what they do well and what could improve. Conducting such training in the context of authentic exchanges with their everyday partners may support positive change in social communication. The present investigation sought to evaluate indices of improved social communication. Method A mixed-methods design was employed for this case series investigation. Quantitative measures include pre- and postoutcomes on goal attainment scales (GASs) and measures of conversational effectiveness. Qualitative measures include responsiveness to video-supported prompts, conversational behaviors, and metacognitive statements. Results Participants perceived gains on GAS of 3-4 SDs, as well as perceived improvements on the La Trobe Communication Questionnaire. Those gains were validated by gains on the adapted Measure of Participation in Conversation and Measure of Skill in Supported Conversation. Individuals with TBI and their partners reached consensus on most goals and postintervention La Trobe Communication Questionnaire ratings. Participants made accurate judgments about their behaviors at a high rate, given video review. Conversational behaviors and use of metacognitive statements varied across participants and conversational contexts. Field notes and session transcripts provide evidence that both dyads increased internalization of VSM goals and purpose. Conclusions Joint VSM shows promise as a method for eliciting accurate self-assessments among individuals with TBI and their close partners. Both dyads perceived positive gains in interactions within and outside their dyads. Furthermore, joint VSM and GAS appear to improve self-awareness and internalization of VSM goals and purpose.

Prediction of quality of life by Helsinki computed tomography scoring system in patients with traumatic brain injury

PURPOSE

The aim of this study is to assess the association between the Computed Tomography (CT) findings on admission, according to the Helsinki computed tomography CT score, and patient's Quality of Life (QoL) following traumatic brain injury (TBI) in Lebanon.

METHODS

A retrospective study was performed on 49 males suffering from war induced TBI. Participants were stratified into two groups based on the date of injury. Helsinki CT score was calculated for CT scans of participants. Outcomes were assessed using QoL scales including the Project for the Epidemiological Analysis of Critical Care Patients scale (PAEEC).

RESULTS

Correlation analysis showed that QoL, up to 4 years post-TBI, was significantly associated with Helsinki CT classification. Group 1 of subjects living with TBI for 1-2 years revealed a correlation coefficient r = 0.536, p-value = 0.027, whereas, group 2 including subjects who are injured since 3-4 years, had a correlation coefficient r = 0.565, p-value = 0.001.

CONCLUSION

The present study showed that patients with traumatic brain injury experienced significant quality of life deterioration up to 4 years post-TBI. Our findings propose the important role of Helsinki score in predicting the quality of life among patients with TBI.

Metacognitive knowledge and functional outcomes in adults with acquired brain injury: A meta-analysis

Pronounced difficulties in functional outcomes often follow acquired brain injury (ABI), and may be due, in part, to deficits in metacognitive knowledge (being unaware of one's cognitive strengths and limitations). A meta-analytic review of the literature investigating the relationship between metacognitive knowledge and functional outcomes in ABI is timely, particularly given the presence of apparently inconsistent findings. Twenty-two articles revealed two distinct methods of measuring metacognitive knowledge: (1) absolute (the degree of inaccurate self-appraisal regardless of whether the error tends towards under- or over-confident estimations) and (2) relative (the degree and the direction of the inaccuracy) discrepancy. Separate meta-analyses were conducted for absolute and relative discrepancy studies to assess the relationship between metacognitive knowledge and functional outcomes (affect-related quality of life, family and community integration, and work outcomes). The pattern of results found suggested that better metacognitive knowledge is related to better overall functional outcomes, but the relationship may differ depending on the outcome domain. These findings generally support the importance of focusing on metacognitive knowledge to improve outcomes following ABI. Nonetheless, the relatively small effect sizes observed suggest that other predictors of functional outcome should be investigated, including other subdomains of metacognition.

Setting and achieving individualized social communication goals for people with acquired brain injury (ABI) within a group treatment

BACKGROUND

Cognitive-communication disorders are common following an acquired brain injury (ABI). Remediation should involve individualized goal-setting, yet few reports describe the effectiveness of setting communication goals in a group setting.

AIMS

To describe a process for setting and achieving goals for people with ABI.

METHODS & PROCEDURES

A total of 21 participants with ABI participated in a group treatment (triads and dyads) over 6 weeks (20 h in total). Specific social communication goals were set using goal attainment scaling (GAS) with the participant and their communication partner. Goals targeted strategy use that accounted for existing cognitive abilities. The participant and their communication partner evaluated the goals post-treatment and 6-8 weeks later. Data were analysed using Friedman's test to identify the achievement of GAS goals.

OUTCOMES & RESULTS

A total of 20 participants recalled goals independently post-treatment. Significant improvement post-treatment on GAS goals was rated by both the participant (p < 0.001) and their communication partner (p < 0.001). This improvement was maintained at follow-up. No significant differences in ratings were found between participants and their communication partners at either time point.

CONCLUSIONS & IMPLICATIONS

Individualized social communication goals can be set and achieved for people with ABI in group treatment, even when participants are several years post-injury. GAS offers a method for structuring and quantifying goal progress. Involving communication partners and cognitive strategies were effective in improving communication.

Reporting on novel complex intervention development for adults with social communication impairments after acquired brain injury

PURPOSE

Interventions are often poorly described in published controlled trials, with relatively little information regarding intervention development, content and fidelity. This makes it difficult to conduct replication studies, interpret and compare findings across studies and for therapists to deliver the intervention in clinical practice. Complete reporting of interventions (including fidelity) is now recommended for treatment studies, and this standardized approach is achieved using the Template for Intervention Description and Replication (TIDieR). The aim of this article is to describe the multi-phase process of developing a novel intervention for adults with acquired brain injury (ABI) and report on the findings from involving practicing therapists in this process.

METHODS

Phase 1 involved a review of relevant literature and specifying the intervention as a prototype intervention manual. Phase 2 comprised a focus group with eight practicing therapists exploring their experiences and perceptions of the intervention, potential active components, and essential elements; it also included a review of the prototype manual. Data from the focus group discussion was transcribed and analyzed thematically. Phase 3 investigated actual fidelity of the intervention undertaken, achieved by observers viewing videoed sessions and appraising against the fidelity checklist, which was then analyzed using Cohen's kappa.

RESULTS

Project-based intervention was defined as having six essential elements: a project or tangible end product focus; group-based intervention; individualized communication-based goals; communication partner involvement; acknowledgement and support of participants' cognitive ability; and consideration and plan to address impaired awareness. Analysis of focus group data revealed four themes of essential elements; group context; therapeutic skills; and manual core components and informed the development of a fidelity checklist with 13 essential and 6 desirable criteria. Fidelity assessed using percent agreement was acceptable for almost all rater pairs; where significant, Kappa coefficients had values ranging from poor to excellent (k = 0.34-1.0) depending on rater pair and session.

DISCUSSION

The TIDieR framework provided a clear systematic approach for the complete description and reporting of a complex communication intervention for people with ABI. This article comprehensively described the development and manualisation of intervention in collaboration with practicing therapists which can be used for future testing. In addition, the process undertaken has the potential to inform rehabilitation researchers in other fields on the development of complex interventions.Implications for rehabilitationThe results of this study detail the steps needed to describe an intervention, from the identification of the essential elements through to the creation of a manual and checklist to show fidelity. The process provides a starting point for other rehabilitation researchers developing complex interventions.This article provides a clear and comprehensive description of a novel intervention containing six essential elements for people with acquired brain injury presenting with communication impairments.Project-based intervention is one intervention, which intends to help improve communication skills and quality of life in people with acquired brain injury.This study highlights the important role practicing therapists can play in the creation of an intervention manual and fidelity checklist and in ensuring that sufficient detail is provided to help therapists implement the intervention into clinical practice.

Depression, apathy and impaired self-awareness following severe traumatic brain injury: a preliminary investigation

Primary Objective: The primary aim of this study was to determine the frequency of severe impaired self-awareness (ISA) in patients with severe traumatic brain injury (TBI) and the correlates of selected clinical, neuropsychiatric and cognitive variables. The secondary aim of the study was to assess depression and apathy on the basis of their level of self-awareness. Methods: Thirty patients with severe TBI and 30 demographically matched healthy control subjects (HCs) were compared on measures of ISA, depression, anxiety, alexithymia, neuropsychiatric symptoms and cognitive flexibility. Results: Twenty percent of the patients demonstrated severe ISA. Severe post-acute ISA was associated with more severe cognitive inflexibility, despite the absence of differences in TBI severity, as evidenced by a Glasgow Coma Scale (GCS) score lower than 9 in all cases in the acute phase. Patients with severe ISA showed lower levels of depression and anxiety but tended to show more apathy and to have greater difficulty describing their emotional state than patients with severe TBI who showed minimal or no disturbance in self-awareness. Conclusion: These findings support the general hypothesis that severe ISA following severe TBI is typically not associated with depression and anxiety, but rather with apathy and cognitive inflexibility.

Do stroke survivors agree with their clinicians on the extent of their post-stroke activity limitation and participation restriction?

This study aimed to examine discrepancies in the reporting of post-stroke functioning between stroke survivors and their clinicians across various disability domains and across current and predicted functioning. Fifty sub-acute stroke survivors (Age M = 70.30 SD = 15.80, 56% female) and their occupational therapist independently completed three measures assessing activity limitations (cognitive, physical, instrumental) and participation restrictions. Assessments were made of current functioning and predicted functioning at three months' post-discharge. Compared to physical functioning, appraisal discrepancies were more pronounced for cognitive functioning, instrumental activity limitation, and participation restriction. Discrepancies were more pronounced for current, as opposed to predicted, cognitive functioning (Z = -4.21, p < .001) and instrumental activity limitation (Z = -4.00, p < .001). Conversely, discrepancies in participation restriction were greatest for predicted functioning (Z = -4.03, p < .001). Follow-up (n = 39) showed that, compared to survivors' predictions, clinicians' predictions were more closely aligned with actual stroke survivor functioning at three months' post-discharge (as rated by a close other). These findings suggest appraisal discrepancy varies across disability domains and time reference points, with cognitive and complex functional activities being particularly discrepant between stroke survivors and clinicians. Furthermore, clinicians may hold more realistic expectations of short-term functional recovery.

Injury Severity and Depressive Symptoms in a Post-acute Brain Injury Rehabilitation Sample

This study explored the relationship between injury severity and depressive symptoms for treatment-seeking individuals with traumatic brain injury (TBI). The Mayo Classification System was used to classify TBI severity in 72 participants who completed the Patient Health Questionnaire at admission and at dismissal from rehabilitation. Patients with mild TBI reported more depressive symptoms than those with moderate or severe TBI at admission and at dismissal. Although injury severity groups differed by gender composition, gender had no effect on severity of depressive symptoms. All participants reported fewer depressive symptoms at dismissal from rehabilitation, including lower endorsement of dysphoria by discharge. Participants with mild TBI, however, continued to report depressive symptoms of a mild severity at dismissal, with residual problems with anhedonia. These findings underscore the benefit of interdisciplinary post-acute rehabilitation services for persons with TBI of any severity, including those with mild injury.

Assessing Anosognosia in Apraxia of Common Tool-Use With the VATA-NAT

In neurological patients, a lack of insight into their impairments can lead to possibly dangerous situations and non-compliance in rehabilitation therapy with worse rehabilitation outcomes as a result. This so called anosognosia is a multifaceted syndrome that can occur after brain damage affecting different neurological or cognitive functions. To our knowledge no study has investigated anosognosia for apraxia of common tool-use (CTU) so far. CTU-apraxia is a disorder frequently occurring after stroke that affects the use of familiar objects. Here, we introduce a new questionnaire to diagnose anosognosia for CTU-apraxia, the Visual Analogue Test assessing Anosognosia for Naturalistic Action Tasks (VATA-NAT). This assessment is adapted from a series of VATA-questionnaires that evaluate insight into motor (VATA-M) or language (VATA-L) impairment and take known challenges such as aphasia into account. Fifty one subacute stroke patients with left (LBD) or right (RBD) brain damage were investigated including patients with and without CTU-apraxia. Patients were assessed with the VATA-L, -M and -NAT before and after applying a diagnostics session for each function. Interrater reliability, composite reliability as well as convergent and divergent validity were evaluated for the VATA-NAT. Seven percent of the LBD patients with CTU-apraxia demonstrated anosognosia. After tool-use diagnostics this number increased to 20 percent. For the VATA-NAT, psychometric data revealed high interrater-reliability (τ ≥ 0.828), composite reliability (CR ≥ 0.809) and convergent validity (τ = -0.626). When assessing patients with severe aphasia, the possible influence of language comprehension difficulties needs to be taken into account for interpretation. Overall, close monitoring of anosognosia over the course of rehabilitation is recommended. With the VATA-NAT we hereby provide a novel assessment for anosognosia in patients with CTU-apraxia. For diagnosing anosognosia we recommend to combine this new tool with the existing VATA-M and -L subtests, particularly in patients who demonstrate severe functional deficits.

Development and content validity of the behavioral assessment screening tool (BASTβ)

PURPOSE

Develop and establish the content validity of the Behavioral Assessment Screening Tool (BAST_β), a self-reported measure of behavioral and emotional symptoms after traumatic brain injury.

METHODS

This was an assessment development study, including two focus groups of individuals with traumatic brain injury (n = 11) and their family members (n = 10) and an expert panel evaluation of content validity by experts in traumatic brain injury rehabilitation (n = 7). We developed and assessed the Content Validity Index of the BAST_β.

RESULTS

The BAST_β initial items (n = 77) corresponded with an established conceptual model of behavioral dysregulation after traumatic brain injury. After expert panel evaluation and focus group feedback, the final BAST_β included 66 items (60 primary, 6 branching logic) rated on a three-level ordinal scale (Never, Sometimes, Always) with reference to the past two weeks, and an Environmental Context checklist including recent major life events (n = 23) and four open-ended questions about environmental factors. The BAST_β had a high Content Validity Index of 89.3%.

CONCLUSION

The BAST_β is a theoretically grounded, multidimensional self-reported assessment of behavioral dysregulation after traumatic brain injury, with good content validity. Future translation into mobile health modalities could improve effectiveness and efficiency of long-term symptom monitoring post-traumatic brain injury. Future work will establish and validate the factor structure, internal consistency reliabilities and other validities of the BAST. Implications for Rehabilitation Behavioral problems after traumatic brain injury is one of the strongest contributing factors to poor mood and community integration outcomes after injury. Behavior is complex and multidimensional, making it a challenge to measure and to monitor long term. The Behavioral Assessment Screening Tool (BAST) is a patient-oriented outcome assessment developed in collaboration with individuals with traumatic brain injury, their care partners, and experts in the field of traumatic brain injury rehabilitation to be relevant and accessible for adults with traumatic brain injuries. The BAST is a long-term monitoring and screening tool for community-dwelling adults with traumatic brain injuries, to improve identification and management of behavioral and emotional sequelae.

Spectrum of outcomes following traumatic brain injury-relationship between functional impairment and health-related quality of life

Background

The outcome following traumatic brain injury (TBI) is heterogeneous and poorly defined and physical disability scales like the extended Glasgow Outcome Score (GOSE) while providing valuation information in terms of broad categorisation of outcome are unlikely to capture the full spectrum of deficits. Quality of life questionnaires such as SF-36 are emerging as potential tools to help characterise factors important to patients’ recovery. This study assessed the association between physical disability and subjective health rating. The relationship is of value as it may help evaluate the impact of TBI on patients’ lives and facilitate the delivery of appropriate neuro-rehabilitation services.

Methods

A single-centre retrospective study was undertaken to assess the relationship between physical outcome as measured by GOSE and quality of life captured by the SF-36 questionnaire. Cronbach’s alpha was calculated for each of the eight SF-36 domains to measure internal consistency of the test. Multivariate analysis of variance was conducted to look at the association between GOSE and the physical (PCS) and mental (MCS) component scores on the SF-36. Finally, we performed a generalised linear mixed model (GLMM) to assess the relative contribution of GOSE score, age at the time of trauma, sex and TBI duration towards MCS and PCS rating.

Results

There is a statistically significant difference in the MCS and PCS scores based on patients’ GOSE scores. The mean scores of the eight SF-36 domains showed significant association with GOSE. GLMM demonstrated that GOSE was the strongest predictor of PCS and MCS. Age was an important variable in the PCS score while time following trauma was a significant predictor of MCS rating.

Conclusions

This study highlights that patients’ physical outcome following TBI is a strong predictor of the subjective mental and physical health. Nevertheless, there remains tremendous variability in individual SF-36 scores for each GOSE category, highlighting that additional factors play a role in determining quality of life.

Psychological traits predict impaired awareness of deficits independently of neuropsychological factors in chronic traumatic brain injury

OBJECTIVES

To dissociate injury-related factors from psychological contributions to impaired awareness of deficits following traumatic brain injury (TBI); impaired awareness is theorized to partly reflect psychological factors (e.g., denial), but empirical evidence for this theory is scarce.

DESIGN

We examined how different factors predict awareness in patients undergoing rehabilitation (N = 43). Factors included (1) neurological (injury severity), (2) neuropsychological loss, (3) psychological (denial, projection, identification), and (4) personality (narcissism).

METHODS/MAIN MEASURES

The Patient Competency Rating Scale, comparing patient with clinician reports on different functional domains; the Thematic Apperception Test, an injury-independent measure of the propensity to mobilize specific defence mechanisms; and the Narcissism Personality Inventory.

RESULTS

Impaired awareness was not predicted by injury-related and neuropsychological scores but was significantly predicted by use of primitive defence mechanisms (denial and projection). Patients who underestimate their abilities also demonstrated high denial levels, but contrary to underestimators, this was positively related to depression and negatively to awareness.

CONCLUSIONS

Primitive defence mechanism use significantly contributes to impaired awareness independent of injury-related factors, particularly in domains associated with self-identity. Well-validated tests of defence mechanism mobilization are needed to support clinical interpretation of and intervention with impaired awareness. More research is needed to understand the psychology of hypersensitivity to deficits.

PRACTITIONER POINTS

This study provides an empirical demonstration of dissociable contributions of neurological and psychological factors to awareness of deficits in TBI. Trait proclivity to mobilize defence mechanisms in response to anxiety-provoking situations can be measured, and strongly predicts impaired awareness. Importantly, measures of psychological reactions were independent of responses to the neurological deficits themselves, discriminating between psychological and neurological contributions to impaired awareness. The importance of identifying psychological reactions to impaired awareness and hindering rehabilitation success is highlighted, and vital for clinicians to consider during the rehabilitation process. Psychological reactions to TBI can be identified using well-validated, quantitative measures of the use of psychological defences (e.g., Cramer's Thematic Apperception Test scoring system), and the authors suggest this is a critical step to properly characterize and manage awareness in patients during treatment. Although only TBI patients were examined, the results may inform impaired awareness that occur as a result of other disorders and illnesses. The patients in this study were in the chronic stages of the injury, and therefore, the results may not generalize to patients in more acute stages.

Self-awareness rehabilitation after Traumatic Brain Injury: A pilot study to compare two group therapies

BACKGROUND AND PURPOSE

Deficits of self-awareness (SA) are very common after severe acquired brain injury (sABI), especially in traumatic brain injury (TBI), playing an important role in the efficacy of the rehabilitation process. This pilot study provides information regarding two structured group therapies for disorders of SA.

METHODS

Nine patients with severe TBI were consecutively recruited and randomly assigned to one SA group therapy programme, according either to the model proposed by Ben-Yishay & Lakin (1989) (B&L Group), or by Sohlberg & Mateer (1989) (S&M Group). Neuropsychological tests and self-awareness questionnaires were administered before and after a 10 weeks group therapy.

RESULTS

Results showed that both SA and neuropsychological functioning significantly improved in both groups.

CONCLUSION

It is important to investigate and treat self-awareness, also to improve the outcome of neuropsychological disorders. The two group therapies proposed seem to be specific for impulsivity and emotional dyscontrol and for cognitive disorders.

Investigating the relationship between reduced self-awareness of falls risk, rehabilitation engagement and falls in older adults

The present study aimed to investigate whether self-awareness of falls risk is associated with rehabilitation engagement, motivation for rehabilitation, and number of falls after hospital discharge. The sample comprised 91 older adults (M_age=77.97, SD=8.04) undergoing inpatient rehabilitation. The Self-Awareness of Falls Risk Measure (SAFRM) was used to measure different aspects of self-awareness. The treating physiotherapist and occupational therapist rated the patient's engagement in rehabilitation and the patient reported his/her motivation for treatment. Falls information was collected from the patient and significant other once a month for three months following hospital discharge. Significant correlations were found between physiotherapist-rated engagement and intellectual (r_s=-0.22, p<0.05) and anticipatory awareness (r_s=-0.24, p<0.05). Occupational therapist-rated engagement and patient-reported motivation for rehabilitation was correlated with emergent awareness (r_s=-0.38 and -0.31, p<0.05, respectively) and overall self-awareness (r_s=-0.31 and -0.26, p<0.05, respectively). Regression analyses indicated that overall self-awareness provided a unique contribution to occupational therapist-rated engagement when controlling for age, gender, cognition and functional ability. Falls were reported by 29.9% of participants, however, self-awareness did not differ significantly between fallers and non-fallers. The findings suggest that self-awareness of falls risk is associated with rehabilitation engagement and motivation. Therefore, improving patient self-awareness of falls risk may increase engagement in therapy leading to better patient outcomes.

Reliability and sensitivity to change of measurement instruments used in a traumatic brain injury population

Objective: To compile a minimum data set for the follow-up of traumatic brain injury patients from discharge from hospital to one year post injury to assess functioning and participation in the physical, cognitive and psychosocial domains, and in quality of life.

Design: Repeated questionnaire interviews by two observers to establish interobserver reliability of the measurement instruments at discharge and at one year post injury, as well as their sensitivity to change over time in traumatic brain injury patients.

Setting: Department of neurosurgery of an academic hospital, department of a rehabilitation centre, and at the patients' homes in the Netherlands.

Subjects: The study at discharge included 25 patients aged 18-50 years with a moderate to severe traumatic brain injury (Glasgow Coma Scale score 3-14), whereas the one year post injury study included 14 patients aged 19-51 years.

Main (outcome) measures: Physical domain: Barthel Index (BI), Functional Independence Measurement (FIM), Glasgow Outcome Scale (GOS), GOS Extended (GOSE). Cognitive domain: Disability Rating Scale (DRS), Functional Assessment Measurement (FAM), Levels of Cognitive Functioning Scale (LCFS), Neurobehavioural Rating Scale (NRS). Psychosocial domain: Community Integration Questionnaire (CIQ), Employability Rating Scale (ERS), Frenchay Activity Index (FAI), Multi Health Locus of Control (MHLC), Rehabilitation Activities Profile (RAP), Social Support List (SSL), Supervision Rating Scale (SRS), Wimbledon Self Reporting Rating Scale (WSRS). Quality of life: Coop/Wonca Charts (Coop), Rand SF-36 (Rand-36), Sickness Impact Profile-68 (SIP-68).

Results: At both discharge and at one year post injury, in the physical domainthe FIM showed excellent squared weighted kappa (SWK ranging from 0.75 to 0.80), and intraclass correlation coefficient (ICC ranging from 0.75 to 0.92), and a relatively small standard error of measurement (SEM 3.22) and smallest detectable difference (SDD 8.92). In the cognitive domain the FAM and the NRS showed excellent SWK, and ICC, and a relatively small SEM and SDD. In the psychosocial domainthe FAI showed excellent SWK (0.89), and ICC (0.87), and a relatively small SEM (2.64) and SDD (7.31). For quality of life, at both discharge and at one year post injury the SIP-68 and the Coop showed excellent SWK (0.87), and ICC (0.89), and a relatively small SEM (3.79) and SDD (10.51). At both time points SWK and ICC ranged from 0.80 to 0.89, SEM ranged from 1.47 to 1.98, and the SDD was 4.07.

Conclusions: An example of a reliable minimum data set that is also able to detect changes over time is: the FIM, the FAM and the Coop for the early stages in recovery, extended with the NRS, the FAI, and the SIP-68 later in recovery, thereby covering all relevant domains after traumatic brain injury.

The efficacy and safety of extended-release methylphenidate following traumatic brain injury: a randomised controlled pilot study

OBJECTIVE

To investigate the feasibility, safety and efficacy of extended-release methylphenidate in enhancing processing speed, complex attentional functioning and everyday attentional behaviour after traumatic brain injury.

DESIGN

Seven week randomised, placebo-controlled, double-blind, parallel pilot study.

SETTING

Inpatient and outpatient Acquired Brain Injury Rehabilitation Program.

PARTICIPANTS

Eleven individuals with reduced processing speed and/or attention deficits following complicated mild to severe traumatic brain injury.

INTERVENTIONS

Participants were allocated using a blocked randomisation schedule to receive daily extended-release methylphenidate (Ritalin^® LA at a dose of 0.6 mg/kg) or placebo (lactose) in identical capsules.

MAIN OUTCOMES

Tests of processing speed and complex attention, and ratings of everyday attentional behaviour were completed at baseline, week 7 (on-drug), week 8 (off-drug) and 9 months follow-up. Vital signs and side effects were monitored from baseline to week 8.

RESULTS

Three percent ( n = 11) of individuals screened participated (mean post-traumatic amnesia duration = 63.80 days, SD = 45.15). Results were analysed for six and four individuals on methylphenidate and placebo, respectively. Groups did not differ on attentional test performance or relative/therapist ratings of everyday attentional behaviour. One methylphenidate participant withdrew due to difficulty sleeping. Methylphenidate was associated with trends towards increased blood pressure and reported anxiety.

CONCLUSION

Methylphenidate was not associated with enhanced processing speed, attentional functioning or everyday attentional behaviour after traumatic brain injury. Alternative treatments for attention deficits after traumatic brain injury should be explored given the limited feasibility of methylphenidate in this population.

Facilitating Transfer of Skills and Strategies in Occupational Therapy Practice: Practical Application of Transfer Principles

In Occupational Therapy (OT) practice, practitioners assume that the skills and strategies taught to clients during rehabilitation will transfer to performance and participation in everyday life. Despite transfer serving as a practice foundation, outcome studies conclude that this assumption of transfer is not occurring and it often results in decreased efficacy of rehabilitation. This paper investigated key aspects of transfer and found concepts in the psychology literature that can support transfer of skills and strategies in OT. Six key principles proposed from educational psychology can serve as a guide for practitioners to better train for transfer. In this paper, we discuss the six principles and apply concepts from psychology. Each principle is supported with examples of how they may be incorporated OT practice. If occupational therapists understand these principles and implement them in treatment, the efficacy of treatment may improve for many populations.

Reporting of neuropsychological dysfunction remains discrepant between individuals with traumatic brain injury and their close others up to five years post-injury

PURPOSE

The degree to which individuals with traumatic brain injury (TBI) and their close others share a common understanding and experience of post-injury neuropsychological changes is currently unclear. The aim of this preliminary study was to longitudinally examine levels of agreement between self and close other reports of neuropsychological dysfunction following TBI and explore factors associated with these agreement levels.

METHOD

Sixty-three people with TBI and their nominated close others independently completed the Structured Outcome Questionnaire at 1- and 5-years post-injury, reporting whether the person with TBI was experiencing any negative cognitive, behavioural or emotional changes compared to pre-injury.

RESULTS

Agreement levels between pair members ranged from chance to approximately 75% across neuropsychological domains and did not significantly change over 1- and 5-year time points. In the case of pair disagreement, close others were generally more likely to report difficulties. Pair disagreement was significantly associated with close other anxiety.

CONCLUSIONS

Agreement between self and close others remains limited up to 5-years post-injury which questions the practice of using these reports interchangeably in research and clinical practice. Preliminary findings suggest some association between pair disagreement and close other psychological function; however, further research is warranted. Implications for Rehabilitation Reporting of neuropsychological dysfunction between individuals with TBI and their close others is not sufficiently reliable to warrant interchangeable use within research or clinical practice. Including both individuals with TBI and their close others in clinical assessments will facilitate a more holistic understanding of the client's difficulties and their relationships with those close to them. Preliminary findings indicate that disagreement between individuals with TBI and their close others may be associated with close other anxiety. Clinicians should be aware of the potential for disagreement to impact on the psychological health of close others.

Patient Effort in Traumatic Brain Injury Inpatient Rehabilitation: Course and Associations With Age, Brain Injury Severity, and Time Postinjury

OBJECTIVE

To describe patients' level of effort in occupational, physical, and speech therapy sessions during traumatic brain injury (TBI) inpatient rehabilitation and to evaluate how age, injury severity, cognitive impairment, and time are associated with effort.

DESIGN

Prospective, multicenter, longitudinal cohort study.

SETTING

Acute TBI rehabilitation programs.

PARTICIPANTS

Patients (N=1946) receiving 138,555 therapy sessions.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Effort in rehabilitation sessions rated on the Rehabilitation Intensity of Therapy Scale, FIM, Comprehensive Severity Index brain injury severity score, posttraumatic amnesia (PTA), and Agitated Behavior Scale (ABS).

RESULTS

The Rehabilitation Intensity of Therapy Scale effort ratings in individual therapy sessions closely conformed to a normative distribution for all 3 disciplines. Mean Rehabilitation Intensity of Therapy Scale ratings for patients' therapy sessions were higher in the discharge week than in the admission week (P<.001). For patients who completed 2, 3, or 4 weeks of rehabilitation, differences in effort ratings (P<.001) were observed between 5 subgroups stratified by admission FIM cognitive scores and over time. In linear mixed-effects modeling, age and Comprehensive Severity Index brain injury severity score at admission, days from injury to rehabilitation admission, days from admission, and daily ratings of PTA and ABS score were predictors of level of effort (P<.0001).

CONCLUSIONS

Patients' level of effort can be observed and reliably rated in the TBI inpatient rehabilitation setting using the Rehabilitation Intensity of Therapy Scale. Patients who sustain TBI show varying levels of effort in rehabilitation therapy sessions, with effort tending to increase over the stay. PTA and agitated behavior are primary risk factors that substantially reduce patient effort in therapies.

Positive Person–Environment Factors as Mediators of the Relationship Between Perceived Burden and Quality of Life of Caregivers for Individuals With Traumatic Brain Injuries

The purpose of this study was to determine whether personal (caregiving mastery and problem-solving coping) and environmental (social support and professional and community support) caregiver resources mediate the relationship between caregiver perceived burden and quality of life (QOL). The sample consisted of 108 caregivers recruited from support groups who were predominantly White women. The majority of care-recipients had a severe head injury. Measures administered were the Interpersonal Support Evaluation List, the COPE, Family Needs Questionnaire, Modified Caregiving Appraisal Scale, and the World Health Organization Quality of Life–Brief Version. Results showed that social, professional, and community supports mediate the link between perceived burden and QOL. Caregivers of persons with traumatic brain injury frequently face elevated levels of burden, stress, and depression. Positive personal and environmental support, particularly social support, professional/community supports, and mastery, could lessen the negative impact of caregiving burden on QOL of the caregiver.

Pilot feasibility of an mHealth system for conducting ecological momentary assessment of mood-related symptoms following traumatic brain injury

OBJECTIVE

This study assessed pilot feasibility and validity of a mobile health (mHealth) system for tracking mood-related symptoms after traumatic brain injury (TBI).

DESIGN

A prospective, repeated measures design was used to assess compliance with daily ecological momentary assessments (EMA) conducted via a smartphone application over an 8-week period.

METHODS

An mHealth system was developed specifically for individuals with TBI and utilized previously validated tools for depressive and anxiety symptoms (Patient Health Questionnaire-9, Generalized Anxiety Disorder-7). Feasibility was assessed in 20 community-dwelling adults with TBI via an assessment of compliance, satisfaction and usability of the smartphone applications. The authors also developed and implemented a clinical patient safety management mechanism for those endorsing suicidality.

RESULTS

Participants correctly completed 73.4% of all scheduled assessments, demonstrating good compliance. Daily assessments took <2 minutes to complete. Participants reported high satisfaction with smartphone applications (6.3 of 7) and found them easy to use (6.2 of 7). Comparison of assessments obtained via telephone-based interview and EMA demonstrated high correlations (r = 0.81-0.97), supporting the validity of conducting these assessments via smartphone application in this population.

CONCLUSIONS

EMA conducted via smartphone demonstrates initial feasibility among adults with TBI and presents numerous opportunities for long-term monitoring of mood-related symptoms in real-world settings.

Connecting Self-Awareness and Error-Awareness in Patients with Traumatic Brain Injury

Impaired self-awareness after traumatic brain injury (TBI) is often seen in stark contrast to the observations of significant-others, who are acutely aware of the difficulties experienced by patients. Our objective was to investigate the relationship between metacognitive knowledge in daily life and emergent awareness of errors during laboratory tasks, since the breakdown of error detection mechanisms may impose limitations on the recovery of metacognitive knowledge after TBI. We also examined the extent to which these measures of awareness can predict dysexecutive behaviors. A sample of TBI patients (n=62) and their significant-others, provided reports of daily functioning post injury. In addition, patients underwent a neuropsychological assessment and were instructed to signal their errors during go/no-go tests. Interrelationships between metacognitive and emergent levels of awareness were examined, after controlling for the influence of secondary cognitive variables. Significant-other ratings correlated with errors made by the patients on neuropsychological tests but not with their premorbid function. Patients who under-reported daily life difficulties or over-reported their competency, compared to significant-other reports, were less likely to show awareness of laboratory errors. Emergent awareness was also identified as the sole predictor of performance on the modified six-element test, an ecologically valid test of multitasking. The online breakdown of error awareness after brain injury is related to difficulties with metacognitive awareness as reported in daily life, and is also predictive of dysexecutive behaviors. These findings are discussed in the context of multidimensional and neural models of awareness and error monitoring.

The manifestation of anxiety disorders after traumatic brain injury: a review

The development of anxiety disorders after a traumatic brain injury (TBI) is a strong predictor of social, personal, and work dysfunction; nevertheless, the emergence of anxiety has been largely unexplored and poorly understood in the context of TBI. This article provides an overview of the limited published research to date on anxiety disorders that are known to develop after TBI, including post-traumatic stress disorder, generalized anxiety disorder, obsessive-compulsive disorder, panic disorder, specific phobia, and social anxiety disorder. This review also examines diagnostic criteria, the epidemiology of each disorder, and the factors that influence the expression of these conditions, including injury-related and psychosocial variables. Putative neural correlates will be reviewed where known. A discussion of current treatment options and avenues for further research are explored.

Connecting clinical and experimental investigations of awareness in traumatic brain injury

Questionnaire-based demonstrations of impaired self-awareness (SA) after traumatic brain injury (TBI) are not always supported by experimental studies of in-the-moment or online awareness. This chapter begins by describing the clinical phenomenon of impaired SA, how it is measured, and why its interdependency with mechanisms of online awareness may provide the scaffolding from which appraisals of cognitive functioning can be accurately revised following a brain injury. We review research that has measured unawareness of errors in routine action in TBI patients and propose more rigorous methodological approaches to studying the emergent properties of awareness with greater clarity in the laboratory. We discuss how neuropsychological and electrophysiologic studies are beginning to inform our understanding of impaired error processing in TBI patients and we highlight recent theory proposing that online metacognitive processes accumulate evidence of erroneous responses in a graded fashion. Neural signals with amplitudes that scale with the strength of accruing evidence and peak latencies that mark the threshold at which awareness emerges represent important neural mechanisms to examine the breakdown of error awareness after brain injury. We also discuss how errors can be investigated in relation to different sources of evidence that contribute to aware experiences after brain injury. Finally, we explore conditions beyond error signaling, and how different "objects of insight" that require retrospective and prospective judgments of confidence need to be examined in relation to the clinical phenomenon of impaired SA.

An occupation-based video feedback intervention for improving self-awareness: Protocol and rationale

Background.

Impaired self-awareness can limit rehabilitation outcomes for people with traumatic brain injury (TBI). Video feedback on occupational performance has been found to improve self-awareness after TBI when delivered according to specific principles.

Purpose.

The purpose of this article is to describe an occupation-based video feedback intervention found to be effective in a randomized controlled trial to assist with translation into clinical practice.

Key Issues.

The intervention uses therapist-mediated video feedback on clients’ occupational performance, aiming to facilitate self-reflection on performance and improve self-awareness. This paper describes the theoretical background, intervention principles, and protocol of the intervention.

Implications.

Therapists can use video feedback intervention, incorporating the principles in this article, to improve people’s intellectual awareness and ability to recognize and correct errors during task performance after TBI without a negative impact on emotional status.

Development of Self-Awareness After Severe Traumatic Brain Injury Through Participation in Occupation-Based Rehabilitation: Mixed-Methods Analysis of a Case Series

OBJECTIVE. We examined participation in goal planning and development of self-awareness for people with impaired self-awareness after traumatic brain injury.

METHOD. We performed a mixed-methods study of 8 participants recently discharged from inpatient rehabilitation. Self-awareness was measured using discrepancy between self and significant other ratings on the Mayo–Portland Adaptability Index (MPAI–4) at four time points. We calculated effect size to evaluate the change in MPAI–4 discrepancy over time.

RESULTS. Seven participants identified their own goals. We found a large reduction in mean MPAI–4 discrepancy (M = 8.57, SD = 6.59, N = 7, d = 1.08) in the first 6 wk and a further small reduction (M = 5.33, SD = 9.09, N = 6, d = 0.45) in the second 6 wk of intervention. Case data indicated that 7 participants demonstrated some growth in self-awareness.

CONCLUSION. Engagement in occupation-based, goal-directed rehabilitation appeared to foster awareness of injury-related changes to varying extents.

The current practices of speech-language pathologists in providing information to clients with traumatic brain injury

The provision of information about cognitive-communication disorders (CCDs) following traumatic brain injury (TBI) is important given the impact these communication impairments can have on the rehabilitation of people with TBI. This study describes the results of an online survey which investigated the current practices of 74 Australian speech-language pathologists (SLPs) working with adults with TBI. Thirty-seven SLPs outlined their practices in information provision. SLPs reported they provide information to adults with TBI about CCDs, the impact of CCDs on participation in life activities, and rehabilitation from CCDs. In addition, SLPs identified barriers and facilitators to information provision. Barriers identified included time, impairments resulting from TBI, and personal characteristics of the client. Facilitators included family functioning and support and the multidisciplinary team. Findings of this research indicate a need for some changes in the format and content of information that SLPs provide to adults with TBI, to ensure they can achieve fundamental levels of health literacy and better health outcomes.

Self-reported competency--validation of the Norwegian version of the patient competency rating scale for traumatic brain injury

PURPOSE

To evaluate the psychometric properties of the Norwegian version of the Patient Competency Rating Scale (PCRS) in patients with traumatic brain injury (TBI) at 12 months post-injury.

METHODS

Demographic and injury-related data were registered upon admission to the hospital in 148 TBI patients with mild, moderate, or severe TBI. At 12 months post-injury, competency in activities and global functioning were measured using the PCRS patient version and the Glasgow Outcome Scale-Extended (GOSE). Descriptive reliability statistics, factor analysis and Rasch modeling were applied to explore the psychometric properties of the PCRS. External validity was evaluated using the GOSE.

RESULTS

The PCRS can be divided into three subscales that reflect interpersonal/emotional, cognitive, and activities of daily living competency. The three-factor solution explained 56.6% of the variance in functioning. The internal consistency was very good, with a Cronbach's α of 0.95. Item 30, "controlling my laughter", did not load above 0.40 on any factors and did not fit the Rasch model. The external validity of the subscales was acceptable, with correlations between 0.50 and 0.52 with the GOSE.

CONCLUSION

The Norwegian version of the PCRS is reliable, has an acceptable construct and external validity, and can be recommended for use during the later phases of TBI.
