Cognitive-communication difficulties due to traumatic brain injury sustained in adults 55 years and older: A survey of speech-language pathology professional practice in Australia

PURPOSE

Limited research informs management of cognitive-communication difficulties following traumatic brain injury (TBI) in older adulthood. The purpose of this study was to understand the characteristics and practice of speech-language pathologists (SLPs) working with people who sustained TBI at ≥55 years and more specifically their management of cognitive-communication difficulties with this population. This included assessment and treatment practices, resource needs, barriers to practice, and impact to service delivery from COVID-19 restrictions.

METHOD

A cross-sectional survey-based design with non-probability sampling of SLPs working in Australia with adults with TBI was utilised. Descriptive statistics and content analysis were used for analysis of survey data.

RESULT

Fifty responses were eligible for inclusion. Participants predominantly worked in inpatient rehabilitation (48%), acute (40%), and community settings (36%). Service delivery to adults who sustained TBI at ≥55 years commonly included cognitive-communication management. Assessment and treatment trends are described. Most SLPs (74%) perceived barriers to cognitive-communication management, often relating to time and funding, that existed prior to the COVID-19 pandemic. Pandemic restrictions presented additional challenges.

CONCLUSION

Research relating to cognitive-communication difficulties following TBI in older adulthood is required to support evidence-based practice and inform services for older adults who sustain TBI.

Communication between rehabilitation staff and people with traumatic brain injury: A systematic review

This systematic review aimed to synthesize barriers and facilitators in communicative interactions between staff and people with traumatic brain injury (TBI) in the rehabilitation context. Searches captured published evidence up to November 2022 in MEDLINE, Embase, SCOPUS, Web of Science, CINAHL, AMED, and PsycINFO. Eligible studies reported on the communicative interaction between rehabilitation staff and adults with TBI. In total, 31 studies were included in the review; including quantitative, qualitative, and mixed-methods designs. Quality assessment was carried out using standard checklists. Quantitative studies and quantitative components of mixed-method studies were synthesized descriptively according to reported communication barriers and facilitators. Qualitative studies and qualitative components of mixed-method studies were analysed through an inductive thematic meta-synthesis; generating six main themes with four subthemes. Themes were categorized as barriers or facilitators to communicative interaction. Findings demonstrated that cognitive-communication disorders of people with TBI challenge the communicative interaction between rehabilitation staff and people with TBI. However, the extent to which these disorders create a communicative barrier is closely related to staff's communicative approach. While staff holding a collaborative and acknowledging approach and using supportive strategies may facilitate successful communicative interactions, staff using the opposite approach may exacerbate communication barriers.

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.

Primed to cue

The behavioral effects of lexical priming are well studied in the cognitive sciences. Clinical use of the term and widespread implementation of priming based behavioral interventions has remained limited. This is despite the fact that response-contingent cueing, a behavioral intervention technique used during many cognitive-linguistic interventions, is grounded in theories of priming research. The aim of this manuscript is to connect behavioral performance changes observed following priming with those noted following cueing, providing a theoretical rationale for the therapeutic use of both priming and cueing in language and cognitive interventions. In this review, we establish a conceptual basis for how both primes and cues serve to pre-engage the neural system by triggering the retrieval of linked conceptual knowledge, resulting in faster and more accurate responses. Differences between the two (primes and cues) have been linked to timing and conscious intentional engagement, though these distinctions are often task dependent. Additionally, this paper will provide evidence of the clinical utility of priming. Studies of priming in adults with acquired brain injuries are discussed and clinical interventions based on theories of priming are examined. Furthermore, the present work will briefly detail the inhibitory effects of priming to aid clinicians and researchers in deciding how to pair primes and cues with intended retrieval targets. In summation, the present work is intended to bridge two related fields providing both theoretical and clinical insight with respect to the use of primes and cues.

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.

Participants' perspectives of feasibility of a novel group treatment for people with cognitive communication difficulties following acquired brain injury

Purpose: To determine whether treatment was acceptable to participants and perceived as beneficial by exploring the experiences of people with cognitive communication difficulties following acquired brain injury who participated in a novel, group, communication, project-based treatment. The purpose of the treatment was to improve participants' communication skills and quality of life, by focussing group activity towards the production of a project and by incorporating individualised communication goals into group sessions.Methods: Twenty-one people with acquired brain injury recruited from community settings participated in project-based treatment, which comprised one individual and nine group sessions (of 2-3 people) over six weeks. Structured interviews were conducted post-treatment as part of a broader assessment battery. Interviews were transcribed verbatim and analysed using content analysis to identify codes, categories, and themes.Results: Themes identified from the analysis centred around the treatment experience (general experience; group experience; project experience; working on goals) and benefit of treatment (communicative benefit; other benefits; emotional effects; meeting others; something to do). These themes were consistent with the treatment being perceived as acceptable and having initial efficacy for the participant group.Conclusion: The qualitative data presented here provide positive feasibility findings (acceptability and initial efficacy) of project-based treatment for people with acquired brain injury. The results highlight the value of incorporating participants' views in assessing feasibility in developing novel interventions.Implications for rehabilitationInviting people (with cognitive communication difficulties following acquired brain injury) to feedback on their treatment experience provides valuable information that can confirm treatment choice and content or inform adjustments to future treatment.Group treatment with a meaningful and motivating focus, and individualised communication goals, seem to promote positive change in communication, emotional state, cognition, self-awareness, and social interaction.This study highlights the value of individuals' perspectives in evaluating feasibility of a novel intervention.

Changes in discourse structure over time following traumatic brain injury

The objective of the present study was to investigate structural changes in the narrative discourse of individuals with penetrating traumatic brain injury (pTBI) following immediate and delayed story retellings. Additionally, the potential influence of immediate memory, working memory, and executive functions on narrative discourse performance were examined. The narrative discourse of two groups, 123 with pTBI and 44 non-brain injured (NBI), was sampled. Participants were asked to retell a wordless picture story immediately after viewing it and again 30-min later. Story narratives were analyzed using a variety of microlinguistic and macrostructural measures. Results revealed significant group differences of both microlinguistic and macrostructural measures following the immediate retell, but not following the delayed retell. Regression analyses revealed that immediate memory accounted for a modest degree of the explained variance for the production of critical content during narrative discourse. The observed deficits were relatively stable over a short delay (30 min) and appeared attributable, in part, to difficulty with the encoding and consolidation of story content.

Strengthening the quality of longitudinal research into cognitive-communication recovery after traumatic brain injury: A systematic review

PURPOSE

(i) To systematically review longitudinal and prognostic studies relating to the trajectory of cognitive-communication recovery after TBI and (ii) to provide recommendations to strengthen future research.

METHOD

Thirteen health literature databases were accessed up until July 2014.

MAIN MEASURES

Articles were screened systematically against pre-determined inclusion and exclusion criteria. Quality reviews were performed on the selected articles using a modified Downs & Black Rating Scale. Two independent reviewers performed the reviews.

RESULT

Sixteen longitudinal and prognostic articles met the inclusion criteria. There was evidence of either maintenance or improvement of cognitive-communication skills during the first 3 years post-injury. However, the studies did not provide detailed recovery trajectories, by failing to evaluate numerous data points over time. No studies evaluated recovery beyond 3 years post-injury. Injury severity, lesion location, brain volume loss and conversation skills may predict specific cognitive-communication outcomes. There was high variability in study characteristics and measures.

CONCLUSION

There is currently scarce evidence regarding cognitive-communication recovery and prognosis. People with TBI may recover or maintain pre-morbid cognitive-communication skills during the early rehabilitation stage. Further research detailing the recovery trajectory with a view to evaluating predictive factors is strongly indicated. Guidelines for future research are provided.

Identification of hearing loss among residents with dementia: perceptions of health care aides

Effective communication can be difficult when working with individuals with dementia and hearing loss. Given the high prevalence of both dementia and hearing loss among individuals in long term care, direct care providers in this setting, will almost certainly confront frequent communication challenges. To understand health care aide perspectives of caring for residents with dementia and hearing loss, 12 health care aides from five nursing homes participated in audio-recorded, semi-structured interviews. Transcripts were coded and themes were identified. Health care aides reported the difficulties in distinguishing the relative contributions of hearing loss and dementia to communication breakdowns. They reported that familiarity with residents helped them differentiate between sensory versus cognitive impairments in conversations with residents. Although able to identify strategies to support communication, communication difficulty complicated both their provision of care and support of quality of life for residents with dementia and hearing loss. Suggestions for practice and education are provided.
