Conversational topics discussed by individuals with severe traumatic brain injury and their communication partners during sub-acute recovery

Perceptions of communication recovery following traumatic brain injury: A qualitative investigation across 2 years

BACKGROUND

Exploring the perceptions of individuals with traumatic brain injury (TBI) towards their brain injury recovery across the continuum of care may offer insights to support engagement with rehabilitation services. Illness narratives are a potentially valuable avenue for examining perceptions of recovery that may influence engagement.

AIMS

The aim of this study is to explore the perspective of individuals with severe TBI towards their communication, brain injury and recovery experiences at 6 months, 1 year and 2 years post-injury.

METHODS & PROCEDURES

Discourse samples were obtained from 12 participants with severe TBI at 6 months, 1 year and 2 years following injury. A standardised protocol was used to elicit responses relating to perceptions of communication, the brain injury narrative, and perceptions of recovery facilitators. A thematic analysis of the discourse samples was completed.

OUTCOMES & RESULTS

Three overarching themes were identified: experiences of communication recovery are diverse (Theme 1), varied experiences of recovery and rehabilitation (Theme 2), and continuous and lifelong journey of recovery (Theme 3). Primary communication concerns included presence of anomia, dysarthria, conversational topic difficulties, impacts of fatigue and memory difficulties. Illness narratives revealed the importance of re-establishing a sense of self and the perceived importance of a strong social network post-injury.

CONCLUSIONS & IMPLICATIONS

The varied nature of communication challenges and recovery after TBI highlights the need for holistic, multidisciplinary support as well as inclusion of family and friends in the recovery process. Social communication intervention is a perceived priority area for individuals with TBI. Illness narratives may also play a valuable role in therapy and help to shape post-injury identity. Managing the impacts of fatigue on communication and encouraging individuals to take ownership over their recovery and treatment may also help to improve patient outcomes. Supporting individuals to construct positive brain injury narratives that reaffirm a sense of self and include perspectives of family and friends may offer a potential future avenue for rehabilitation. Tailored but flexible, team-based service delivery models for individuals with TBI that span from acute to long-term care are warranted. WHAT THIS STUDY ADDS?: What is already known on this subject Communication recovery from traumatic brain injury (TBI) is complex and multifaceted. The perceptions of individuals with TBI toward their communication recovery is largely unknown. To establish rehabilitation services that meet the needs of these individuals, we need to understand how they experience communication recovery. What this paper adds to existing knowledge Social communication interventions were perceived as a priority for intervention by individuals with TBI. Fatigue was identified as perceived barrier to communication recovery. Taking ownership over one's recovery process was revealed as a facilitator of recovery. Illness narratives were found to strengthen post-injury identity over time. What are the potential or actual clinical implications of this work? Speech pathologists should prioritise social communication interventions and fatigue management for communication. Facilitating ownership of the recovery process and offering long-term supports are key aspects of treatment. Supporting positive illness narratives as part of treatment may facilitate post-injury identity construction.

Communication and Psychosocial Outcomes 2-Years After Severe Traumatic Brain Injury: Development of a Prognostic Model

OBJECTIVE

To examine predictive factors underlying communication and psychosocial outcomes at 2 years post-injury. Prognosis of communication and psychosocial outcomes after severe traumatic brain injury (TBI) is largely unknown yet is relevant for clinical service provision, resource allocation, and managing patient and family expectations for recovery.

DESIGN

A prospective longitudinal inception design was employed with assessments at 3 months, 6 months, and 2 years.

PARTICIPANTS

The cohort included 57 participants with severe TBI (N=57).

SETTING

Subacute and post-acute rehabilitation.

MAIN OUTCOME MEASURES

Preinjury/injury measures included age, sex, education years, Glasgow Coma Scale, and PTA. The 3-month and 6-month data points included speech, language, and communication measures across the ICF domains and measures of cognition. The 2-year outcome measures included conversation, perceived communication skills, and psychosocial functioning. Predictors were examined using multiple regression.

INTERVENTIONS

Not applicable.

RESULTS

The cognitive and communication measures at 6 months significantly predicted conversation measures at 2 years and psychosocial functioning as reported by others at 2 years. At 6 months, 69% of participants presented with a cognitive-communication disorder (Functional Assessment of Verbal Reasoning and Executive Strategies [FAVRES]). The unique variance accounted for by the FAVRES measure was 7% for conversation measures and 9% for psychosocial functioning. Psychosocial functioning at 2 years was also predicted by pre-injury/injury factors and 3-month communication measures. Pre-injury education level was a unique predictor, accounting for 17% of the variance, and processing speed/memory at 3 months uniquely accounted for 14% of the variance.

CONCLUSION

Cognitive-communication skills at 6 months are a potent predictor of persisting communication challenges and poor psychosocial outcomes up to 2 years after a severe TBI. Findings emphasize the importance of addressing modifiable cognitive and communication outcomes variables during the first 2 years after severe TBI to maximize functional patient outcomes.

Exploring the measurement of pediatric cognitive-communication disorders in traumatic brain injury research: A scoping review

OBJECTIVE

To synthesize information about the constructs measured, measurement instruments used, and the timing of assessment of cognitive-communication disorders (CCDs) in pediatric traumatic brain injury (TBI) research.

METHODS AND PROCEDURES

Scoping review conducted in alignment with Arksey and O'Malley's five-stage methodological framework and reported per the PRISMA extension for Scoping Reviews. Inclusion criteria: (a) cohort description, case-control, and treatment studies; (b) participants with TBI aged 5-18 years; (c) communication or psychosocial outcomes; and (d) English full-text journal articles. The first author reviewed all titles, abstracts, and full-text articles; 10% were independently reviewed.

OUTCOMES AND RESULTS

Following screening, a total of 687 articles were included and 919 measurement instruments, measuring 2134 unique constructs, were extracted. The Child Behavior Checklist was the most used measurement instrument and 'Global Outcomes/Recovery' was the construct most frequently measured. The length of longitudinal monitoring ranged between ≤3 months and 16 years.

CONCLUSIONS AND IMPLICATIONS

We found considerable heterogeneity in the constructs measured, the measurement instruments used, and the timing of CCD assessment in pediatric TBI research. A consistent approach to measurement may support clinical decision-making and the efficient use of data beyond individual studies in systematic reviews and meta-analyses.

Discourse Analysis of Humor After Traumatic Brain Injury

Purpose Individuals with cognitive communication difficulties after traumatic brain injury (TBI) often experience difficulties with social communication. Humor is a sociolinguistic skill that requires social, cognitive, emotional, and behavioral skills and, when used effectively, may serve to enhance one's social relationships. There is a paucity of research related to the use of humor in individuals with TBI. This study categorizes humor use in individuals with cognitive communication difficulties after TBI and examines the linguistic construction of these humorous exchanges. Method The humorous exchanges of nine individuals who had cognitive communication difficulties after a moderate-to-severe TBI were examined. Conversations were collected from a community-based communication skills group, categorized using thematic analysis methods, and examined linguistically using the discourse analysis tools of systemic functional linguistics. Results All participants demonstrated the ability to use a variety of categories of humor, and discourse analysis methods revealed humor use as a strength for engaging with others. Examples of such engagement include use of humor to elicit attention, assert authority, share information, acknowledge shared difficulties, and demonstrate affiliation toward their communication partners. Conclusions Discourse analysis of humor can provide speech-language pathologists with important information about the linguistic strengths of individuals with cognitive communication difficulties. This has important implications for clinical service provision.

Psychosocial Outcomes of Severe Traumatic Brain Injury in Relation to Discourse Recovery: A Longitudinal Study up to 1 Year Post-Injury

Purpose The interrelationship between psychosocial outcomes and discourse after severe traumatic brain injury remains largely unknown. This study examines outcomes relating to work, relationships, and independence within the context of discourse recovery across the 1st year post-injury. Method An inception cohort comprising 57 participants with severe traumatic brain injury was assessed at 3, 6, 9, and 12 months post-injury. Outcomes were measured with the Sydney Psychosocial Reintegration Scale-2 (Tate et al., 2012; Tate, Simpson, Loo, & Lane-Brown, 2011), and discourse was evaluated with Main Concept Analysis of a narrative retell. Correlation and linear regression analyses were utilized. Results Significant correlations were found between psychosocial outcomes reported by relatives and discourse performance across the 1st year. The 6-month discourse scores significantly predicted the 12-month psychosocial outcomes reported by relatives. Initial discourse severity and recovery pattern also informed outcomes. Conclusions Discourse disorders have a strong relationship with everyday outcomes relating to work, relationships, and independence as reported by relatives. Six months post-injury is a beneficial time for assessment, education, and service planning. Age, years of education, and aphasia may mediate recovery and outcomes. A clinical decision tree is offered to support goal setting. Supplemental Material https://doi.org/10.23641/asha.9755444.

Social communication following traumatic brain injury part I: State-of-the-art review of assessment tools

PURPOSE

The primary aim of this paper was to identify and describe current social communication assessment tools for adults with traumatic brain injury.

METHOD

We conducted a state-of-the-art review to identify and categorise the range of social communication assessment tools found in the assessment and treatment literature that revealed 42 measures that were coded according to characteristics related to assessment types, psychometrics, and implementation.

RESULT

Of the 42 assessments, 64% evaluated social cognition and the remaining 36% evaluated communication. Coding of implementation categories revealed that only 18/42 (43%) measures were ecologically grounded and 23/42 (55%) were available to clinicians by purchase or in the public domain. Only three measures incorporated questions or an assessment of the examinee's priorities or concerns.

CONCLUSION

A number of factors limit current social communication assessment. The lack of tools that objectively and reliably evaluate communication or social cognition in ecologically valid ways remains problematic. Of particular concern is the lack of prioritisation of the individual's communication values and needs. Recommendations include a call to focus research on the development of more contextual, standardised assessments, consider availability and feasibility when tools are being developed, and evaluate assessment processes as well as discrete tools.

Association between uncooperativeness and the glucose metabolism of patients with chronic behavioral disorders after severe traumatic brain injury: a cross-sectional retrospective study

Bakground

Patients with behavioral disorders following severe traumatic brain injury (sTBI) often have disorders of consciousness that make expressing their emotional distress difficult. However, no standard method for assessing the unsettled and unforeseen responses that are associated with behavioral disorders has yet to be established. Because the thalamus is known to play a role in maintaining consciousness and cognition, we used 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) to examine the association between brain glucose metabolism in the thalamus and behavioral disorders.

Methods

We retrospectively analyzed 70 consecutive patients with sTBI who had been involved in motor vehicle accidents. To assess behavioral disorders, we evaluated 18 symptoms using the Brief Psychiatric Rating Scale (BPRS): Emotional Withdrawal, Conceptual Disorganization, Tension, Mannerisms and Posturing, Motor Retardation, Uncooperativeness, Blunted Affect, Excitement, Somatic Concern, Anxiety, Feeling of Guilt, Grandiosity, Depressive Mood, Hostility, Suspiciousness, Hallucinatory Behavior, Unusual Thought Content, and Disorientation. First, we identified clinical characteristics of sTBI patients with behavioral disorders. Next, we retrospectively analyzed 18F-FDG-PET/CT data to assess how thalamic activity was related with abnormal behaviors.

Results

Twenty-six patients possessed the minimum communicatory ability required for psychiatric interview. Among them, 15 patients (57.7%) were diagnosed with behavioral disorder, 14 of whom had reached a stable psychiatric state after about 426.6 days of treatment. Excitement (13 patients) and uncooperativeness (10 patients) were the most frequently observed symptoms. Available 18F-FDG-PET/CT data indicated that thalamic glucose metabolism was imbalanced and lateralized (p = 0.04) in 6 patients who exhibited uncooperativeness.

Conclusions

Behavioral symptoms of excitement and uncooperativeness were common in patients with sTBI, although most symptoms improved as the chronic stage continued. Our data support the idea that imbalanced laterality of glucose metabolism in the thalamus might be related to behavioral disorders characterized by uncooperativeness.
