Social communication assessment after TBI: a narrative review of innovations in pragmatic and discourse assessment methods

Insights From Important Event Recounts Told by People With Traumatic Brain Injury

PURPOSE

Communication can be chronically impacted by severe traumatic brain injury (TBI), yet there is a critical lack of research investigating communication recovery beyond 12 months postinjury with discourse measures. This longitudinal study aimed to investigate quantitative and qualitative changes in important event recounts produced by a group of people with severe TBI up to 2 years postinjury.

METHOD

A prospective observational design with an inception cohort was adopted. Thirty-four participants with severe TBI were asked to produce an important event recount at 6, 12, and 24 months postinjury. A mixed-methods approach comprised a quantitative analysis of microlinguistic and macrostructural measures, using the automated discourse command EVAL in Computerized Language Analysis (CLAN) and the CLAN Collaborative Commentary tool, respectively. Statistical analysis included a repeated-measures analysis of variance and the Friedman test. An independent qualitative content analysis was also conducted.

RESULTS

The measures revealed significant differences between 6 and 24 months, indicating a protracted recovery trajectory. The microlinguistic analysis showed increased use of revision and repetition over time. The macrostructural analysis indicated changes with orientation to recount characters, evaluative comments, and the number of events or complexity of the recount. The content analysis revealed categories of (a) childhood events, (b) family and relationships, (c) career and education, and (d) grief and loss. Topics at 6 months focused on childhood events and holidays, whereas career and education predominated at 24 months.

CONCLUSIONS

This is the first study to explore important event recounts told by people with severe TBI as they recovered. Participants showed discourse recovery beyond 12 months, highlighting the need for equivalent timing of service provision. The important event recount shows good potential as an ecologically valid assessment tool to evaluate communication recovery that can also be integrated with advances in computerized analysis. Analyses additionally provided insights into potential therapy targets and content categories for chronic discourse impairments.

Story Grammar Analyses Capture Discourse Improvement in the First 2 Years Following a Severe Traumatic Brain Injury

PURPOSE

Narration within a story grammar framework requires speakers to organize characters and events logically. Despite abundant research characterizing narrative deficits following a traumatic brain injury (TBI), the evolution of narrative story grammar over the first 2 years post-TBI has rarely been explored. This study analyzed story grammar in complex narratives of adults with and without severe TBI to (a) examine between-group differences and (b) investigate longitudinal changes over the first 2 years post-TBI.

METHOD

Story grammar analyses of Cinderella narratives from 57 participants with TBI and 57 participants with no brain injury yielded measures of productivity (total number of episodes, total number of story grammar elements), elaboration (total number of elaborated-complete episodes, mean number of episodic elements per episode), and completeness (total number of incomplete episodes). Mann-Whitney U tests compared measures across groups; generalized estimating equation (GEE) models identified predictors of change, including recovery time (3, 6, 9, 12, and 24 months post-TBI) and demographic/injury-related characteristics.

RESULTS

Between-group differences were statistically significant for all productivity and elaboration measures at 3, 6, and 9 months post-TBI; one productivity measure and one elaboration measure at 12 months; and none of the measures at 24 months. GEE models showed significant improvements in all productivity and elaboration measures over the first 24 months post-TBI, with educational attainment and duration of posttraumatic amnesia affecting recovery. Incomplete episodes only showed between-group differences at 12 months and did not capture recovery.

CONCLUSION

Productivity and elaboration are key story grammar variables that (a) differentiate complex narration in individuals with and without severe TBI and (b) capture narrative improvements over the first 2 years post-TBI.

How do speech-language pathologists assess and treat spoken discourse after TBI? A survey of clinical practice

BACKGROUND

Spoken discourse is commonly affected after traumatic brain injury (TBI). Although guidelines recommend prioritizing discourse-level skills in cognitive communication management, previous literature has highlighted challenges in managing discourse clinically. Little is known about how speech-language pathologists (SLPs) assess and treat discourse after TBI.

AIMS

To investigate current SLP practice to determine the alignment of clinical practice with research evidence and recommendations.

METHODS & PROCEDURES

This online survey consisted of 30 questions on SLPs' practice with discourse assessment, analysis and treatment processes, including the materials and methods used and rationales for decision-making. Participants were recruited through national and international SLP professional bodies, TBI-specific or SLP special-interest groups and social media. Survey responses were analysed using descriptive statistics, with free text included to support individual responses.

OUTCOMES & RESULTS

There were 70 participants, from Australia, the United States, UK and New Zealand. Nearly half the participants had over 11 years of experience working with adults with TBI and a quarter had over 20 years of experience. Participants reported that they regularly evaluated the discourse ability of people with TBI, most commonly during spontaneous conversation or with a personal narrative task. Discourse intervention approaches mostly targeted client self-monitoring ability, social skills or conversational interactions. Practice varied dependent on setting, with more SLPs in community or outpatient services undertaking discourse assessment and treatment than in hospital settings.

CONCLUSIONS & IMPLICATIONS

Overall, survey respondents' management of spoken discourse aligned with recommendations in the research literature, incorporating an individualized, goal-based approach. Factors affecting the use of discourse in practice included client-specific factors and needs, availability of time for transcription and analysis, and SLPs' knowledge level and confidence with discourse. Increased knowledge of discourse methods and treatment approaches could help inform decision-making for SLPs working in TBI.

WHAT THIS PAPER ADDS

What is already known on this subject Spoken discourse is one of the most affected areas of communication for people with TBI. Although recent research has provided guidance on assessment and treatment options for TBI discourse, it is unknown how SLPs manage spoken discourse clinically. What this paper adds to existing knowledge This research adds to the limited research on how SLPs across clinical settings and regions manage discourse assessment and treatment. Respondents' practice was generally aligned with recommendations, featuring individualized, goal-based practice. Potential barriers to discourse implementation included client factors and SLP knowledge, training, and service delivery factors. What are the potential or actual clinical implications of this work? This survey provides evidence that clinical translation is starting to occur in this field, but there remains a need for increased knowledge of assessment and treatment methods, training, and TBI-specific resources to better support SLP practice, particularly relating to transcription. Core reporting outcomes in research on TBI discourse management would assist with translation of the findings to practice.

Telehealth administration of narrative and procedural discourse: A UK and US comparison of traumatic brain injury and matched controls

BACKGROUND

Impaired discourse production is commonly reported for individuals with traumatic brain injury (TBI). Discourse deficits can negatively impact community integration, return to employment and quality of life. COVID-19 restrictions have reduced in-person assessment services for people with communication impairments. Advances in telehealth may help speech and language therapists (SLTs) to assess monologic discourse more systematically and improve access to services for patients who may find it difficult to attend in-person.

AIMS

To examine the feasibility of telehealth administration of narrative and procedural discourse tasks with individuals with TBI and matched controls.

METHODS & PROCEDURES

A total of 20 individuals with TBI and 20 healthy controls, aged 18-55 years, were directly recruited from the UK and indirectly recruited from the US. For participants with TBI, time post-injury was at least 3 months with no diagnosis of aphasia. Control participants were matched for sex and as closely as possible for age. Feasibility of measures was based upon the time to administer both narrative tasks, the report of any technological problems, and participant feed. Discourse samples were transcribed verbatim and analysed using story grammar analysis (for narrative discourse) and identification of propositions (for procedural discourse). Interrater reliability was calculated using percentage agreement for 50% of the data. Non-parametric analyses were used to analyse the performance of the two groups.

OUTCOMES & RESULTS

Narrative and procedural discourse samples were collected via telehealth in approximately 10 min with no reported technical difficulties or complaints from any participants. For narrative discourse performance, there were significant differences for the TBI and control groups for measures of complete episodes (p < 0.001) and missing episodes (p = 0.005). No significant group differences were noted for any of the procedural discourse measures.

CONCLUSIONS & IMPLICATIONS

Results support the feasibility of collecting discourse samples via telehealth. Although the participants' discourse performance distinguished the TBI and control groups on the narrative task, no differences between the groups were noted for the procedural task. The narrative discourse task may have been more difficult than the procedural task, or video cue support reduced the cognitive load of the procedural task. This finding suggests the use of more complex procedural tasks without video cue support may be needed.

WHAT THIS PAPER ADDS

What is already known on this subject Although little research has explored the feasibility of administering discourse assessments for individuals with TBI via telehealth, some studies have found that discourse interventions can be feasibly administered via telehealth. It is also well established that individuals with TBI struggle with the supra-structural and macro-linguistic elements of discourse production. Both procedural and narrative discourse tasks have been found to differentiate individuals with TBI from healthy controls. What this paper adds to existing knowledge Few studies have investigated the feasibility of, and procedures for, administering discourse tasks via telehealth. Additionally, the inclusion of multiple types of discourse tasks to parse cognitive-communication abilities is lacking in the current literature. Findings from this study support that narrative and procedural discourse can be feasibly sampled via telehealth and that international collaboration for research on this topic can facilitate such studies. Individuals with TBI performed more poorly on three measures of narrative discourse. No differences between groups were identified for the procedural task. What are the potential or actual clinical implications of this work? Telehealth assessment for discourse provides flexibility for both the individual with TBI and the speech-language therapist and does not compromise the quality of data collected. The administration of discourse tasks and collection of data was not time-consuming and was well accepted by the study participants. Additionally, international research collaboration not only expands potential participation in research but increases the opportunity to recruit and study more diverse groups.

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.

Measuring pragmatic competence of discourse output among Chinese-speaking individuals with traumatic brain injury

OBJECTIVE

Discourse analysis is one of the clinical methods commonly used to assess the language ability of individuals with traumatic brain injury (TBI). However, the majority of published analytic frameworks are not geared for highlighting the pragmatic aspect of discourse deficits in acquired language disorders, except for those designed for quantifying conversational samples. This study aimed to examine how pragmatic competence is impaired and reflected in spoken monologues in Chinese speakers with TBI.

METHODS

Discourse samples of five tasks (personal narrative, storytelling, procedural, single- and sequential picture description) were elicited from ten TBI survivors and their controls. Each discourse sample was measured using 16 indices (e.g., number of informative words, percentage of local/global coherence errors, repeated words or phrases) that corresponded to the four Gricean maxims. Twenty-five naïve Chinese speakers were also recruited to perform perceptual rating of the quality of all 50 TBI audio files (five discourse samples per TBI participant), in terms of erroneous/inaccurate information, adequacy of amount of information given, as well as degree of organization and clarity.

RESULTS

The maxim of quantity best predicted TBI's pragmatic impairments. Naïve listeners' perception of pragmatics deficits correlated to measures on total and informative words, as well as number and length of terminable units. Clinically, personal narrative and storytelling tasks could better elicit violations in pragmatics.

CONCLUSION

Applying Gricean maxims in monologic oral narratives could capture the hallmark underlying pragmatic problems in TBI. This may help provide an additional approach of clinically assessing social communications in and subsequent management of TBI.

The effects of virtual reality immersion on the content and structure of the narrative discourse of healthy adults

BACKGROUND

Narrative discourse is central to effective participation in conversations. When discourse is assessed in people with communication disability, structured tasks (e.g., picture descriptions) provide experimental control, while unstructured tasks (e.g., personal narratives) represent more natural communication. Immersive virtual reality (VR) technology may provide a solution by creating standardized experiences for narrative retell, therefore balancing ecological validity and experimental control in discourse assessment. Research is needed to understand how VR immersion affects narrative retell, first for adults with no communication disability, before application with adults with aphasia or related communication disability.

AIMS

To assess (1) the effects of VR immersion on the linguistic content and structure of narrative retells in a healthy adult population; and (2) whether VR immersion can influence the way a narrative is retold so that the speaker conveys their own experience, rather than the experience of the characters they are watching.

METHODS & PROCEDURES

In this pilot cohort study, 13 healthy adult participants with no reported communication disability watched an animated short film and a comparable immersive VR short film in a randomized order. Participants were asked to retell the events of the story after each condition in as much detail as possible.

OUTCOMES & RESULTS

Mean length of utterance (in morphemes) was significantly higher in the video condition compared with the VR condition. Significantly more first-person pronouns were used in the VR condition compared with the video condition. No other measures of linguistic content or structure were significantly different between the VR and video conditions.

CONCLUSIONS & IMPLICATIONS

Increased morpho-syntactic length and complexity in the video condition may suggest effects of elicitation stimulus on the narrative produced. The larger number of first-person pronouns in the VR condition may reflect that participants experienced a sense of presence in the virtual environment, and therefore were able to retell their communication experience rather than narrating the experiences of characters from an external perspective. Given the increasing need for more functional assessment of discourse in people with communication disability, further research is needed to validate these findings.

WHAT THIS PAPER ADDS

What is already known on this subject As an ecologically valid tool, discourse analysis is often used to assess daily communicative exchanges in adults with acquired communication disability. Clinicians and researchers using narrative discourse assessment must balance the experimental control and diagnostic reference sample capabilities of structured tasks with the ecological validity and real-life transferability of unstructured personal narratives. What this study adds to existing knowledge This study explores the use of immersive VR technologies to create standardized, replicable, immersive experiences as a foundation for narrative discourse assessment. It highlights how the 'sense of presence' in a virtual world can prompt healthy adult speakers to retell a narrative of a personal experience that can be replicated for many different participants. The results suggest that immersive VR narrative assessment for adults with communication disability may balance ecological validity with measurement reliability in discourse assessment. What are the potential or actual clinical observations of this work? Immersion in VR resulted in the production of narratives with morpho-syntactic features that aligned with typical narrative generation, rather than retell. Participants used more first-person pronouns, suggesting retelling of personal experience. Though further study is needed, these preliminary findings suggest clinicians can use immersive VR stimuli to generate structured story generations that balance experimental and diagnostic control with ecological validity in narrative discourse assessment for adults with communication disability.

Developing a Digital Health Intervention for Conversation Skills After Brain Injury (convers-ABI-lity) Using a Collaborative Approach: Mixed Methods Study

BACKGROUND

People with acquired brain injury (ABI) experience communication breakdown in everyday interactions many years after injury, negatively impacting social and vocational relationships. Communication partner training (CPT) is a recommended intervention approach in communication rehabilitation after ABI. Access to long-term services is essential, both in rural and remote locations. Digital health has potential to overcome the challenges of travel and improve cost efficiencies, processes, and clinical outcomes.

OBJECTIVE

We aimed to collaboratively develop a novel, multimodal web-based CPT intervention (convers-ABI-lity) with key stakeholders and evaluate its feasibility for improving conversation skills after brain injury.

METHODS

This mixed methods study consisted of 3 key stages guided by the Integrate, Design, Assess, and Share (IDEAS) framework for developing effective digital health interventions. Stage 1 included the integration of current end-user needs and perspectives with key treatment and theoretical components of existing evidence-based interventions, TBI Express and TBIconneCT. Stage 2 included the iterative design of convers-ABI-lity with feedback from end-user interviews (n=22) analyzed using content analysis. Participants were individuals with ABI, family members, health professionals, and paid support workers. Stage 3 included the evaluation of the feasibility through a proof-of-concept study (n=3). A total of 3 dyads (a person with ABI and their communication partner [CP]) completed 7 weeks of convers-ABI-lity, guided by a clinician. The outcome measures included blinded ratings of conversation samples and self-report measures. We analyzed postintervention participant interviews using content analysis to inform further intervention refinement and development.

RESULTS

Collaborative and iterative design and development during stages 1 and 2 resulted in the development of convers-ABI-lity. Results in stage 3 indicated positive changes in the blinded ratings of conversation samples for the participants with traumatic brain injury and their CPs. Statistically reliable positive changes were also observed in the self-report measures of social communication skills and quality of life. Intervention participants endorsed aspects of convers-ABI-lity, such as its complementary nature, self-guided web-based modules, clinician sessions, engaging content, and novel features. They reported the intervention to be relevant to their personal experience with cognitive-communication disorders.

CONCLUSIONS

This study presents the outcome of using the IDEAS framework to guide the development of a web-based multimodal CPT intervention with input from key stakeholders. The results indicate promising outcomes for improving the conversation skills of people with ABI and their CPs. Further evaluation of intervention effectiveness and efficacy using a larger sample size is required.

An international survey of assessment and treatment practice for discourse in paediatric Acquired Brain Injury

PURPOSE

Guidelines recommend routine discourse assessment and treatment in paediatric acquired brain injury (ABI) but provide little guidance for clinical practice. The degree to which this has influenced the nature of discourse assessment and treatment in clinical practice has not been examined in detail.

METHOD

Speech-language pathologists working in paediatric ABI (clients aged <18 years) in Australia, New Zealand, the UK, the USA, Canada, and the Asia Pacific region were invited to complete a survey of discourse assessment and intervention practices (n = 77).

RESULT

Clinicians from Australia and New Zealand comprised over half of a responses (53%). The largest proportion had over 10 years' experience (60%), worked in the metropolitan area (58%), and with secondary school-age children (64%). Routine discourse assessment was undertaken by 80% of respondents, focussing on a limited range of genres. No preferred intervention approach was identified. One-quarter of clinicians routinely considered holistic factors during clinical decision-making. Limited normative data and treatment evidence, insufficient time and training were identified as clinical barriers.

CONCLUSION

Assessment practices were consistent with guidelines, yet interventions were highly variable, reflecting limited evidence, client heterogeneity, time constraints, and limited training. A biopsychosocial approach to practice was evident, yet a focus on impairment level factors was prominent. Findings support the need for standardised discourse assessment and discourse intervention methods. Translation into practice guidelines would promote consistency and confidence in clinical practice.

Speech and Language Characteristics of Neurologically Healthy Adults When Describing the Modern Cookie Theft Picture: Mixing the New With the Old

PURPOSE

The Modern Cookie Theft picture has recently become available. This study's purpose was to compare (a) speech and language production by neurologically healthy adults (NHAs) given a generic instruction to describe the picture versus instruction to describe it as if talking with someone who was blind and (b) production during the first 90 s versus full samples.

METHOD

One hundred NHAs minus five outliers formed two participant groups. Each group heard either the original or modified task instruction. Transcriptions of resulting descriptions were analyzed regarding duration, word and T-unit productivity, content units (CUs), and main concepts (MCs) both in full and 90-s samples. Identified CUs and MCs were compared with existing lists from previous research.

RESULTS

Significantly longer samples and greater verbosity occurred with the modified versus original instruction even when limiting time to a 90 s maximum. With the modified instruction, CUs included 119 and 138 terms for truncated and full samples, respectively; participants mentioned 98 and 104 CUs, respectively, given the original instruction. MCs expressed were 18 and 19 for truncated and full samples, respectively, given the modified instruction; with the original instruction, this dropped to 11 and 12 MCs for truncated and full samples, respectively. Within samples, CU and MC repetitions were greater given modified rather than original instruction.

CONCLUSIONS

Normative productivity and content generation data are critical for guiding diagnostic efforts and treatment planning. Benefits and detriments associated with differing productivity and content redundancy secondary to varying instructions and analysis time frames are discussed.

Assessment of communication competence in acquired communication disorders: A systematic scoping review

PURPOSE

Individuals with acquired communication disorders (ACDs) experience reduced ability to participate independently in activities of daily life, and maintain interpersonal relationships and psychosocial wellbeing. Communication interventions are designed to optimise communication competence in personally relevant everyday activities. However, the assessment tools speech-language pathologists (SLPs) typically utilise to evaluate communication competence in everyday life are not ideal. To explore the range and availability of assessments used in research to examine functional communication in adults with ACDs.

METHOD

Five databases (Medline, CINAHL, EMBASE, SCOPUS and PsycINFO) were searched to identify assessment or intervention studies evaluating functional communication in adults with ACDs. Functional communication tools utilised in each study were identified. Extracted tools were categorised according to type, target population, consideration of multimodal communication, person-specificity, consideration of context, availability, administration/analysis time and availability of normative/psychometric data.

RESULT

Forty functional communication assessment tools were included. Just over half the tools were performance-based (n = 25), examined different modes of communication (n = 26) and/or considered context (n = 23). Only 14 tools were person-specific. Many of the most comprehensive tools were out of print or considered excessively time consuming to administer and analyse.

CONCLUSION

A paucity of accessible, time-efficient yet comprehensive tools to assess functional communication in ACDs may limit clinical practice and client outcomes. More versatile functional communication assessments incorporating individualised contexts, and the use of modern communication technologies are recommended.

Assessment and rehabilitation of acquired communication disorders in Aboriginal and Torres Strait Islander adults with stroke or traumatic brain injury: a retrospective chart review

PURPOSE

Speech-language pathologists' (SLP) management practices for Aboriginal and Torres Strait Islander adults with acquired communication disorder (ACD), following stroke or traumatic brain injury (TBI), are not well understood. This study explores SLPs' management approaches for ACDs for Aboriginal and Torres Strait Islander adults post-stroke or TBI.

MATERIALS AND METHODS

SLPs' documented notes were analysed from a two-year retrospective medical record review of Aboriginal and Torres Strait Islander adults (≥18 years), admitted to a regional Queensland hospital with principal diagnoses of stroke or TBI.

RESULTS

SLPs frequently used informal approaches to assess ACDs. English-language formal assessment tools were also used in conjunction with the informal approaches. ACD diagnosis was more common in stroke than TBI patients. One-third of patients with ACD received inpatient rehabilitation at the study site. SLPs infrequently documented cultural or linguistic adaptions to assessment or interventions.

CONCLUSIONS

Informal approaches to assess ACDs were commonly employed which may be because they are perceived to be more culturally appropriate. Clinical guidelines for stroke and TBI should accommodate the diversity of cultures and languages. Better consideration of Aboriginal and Torres Strait Islander communication styles and incorporation of these into SLP ACD management approaches may facilitate accurate diagnosis and culturally safe rehabilitation services.Implications for RehabilitationInformal approaches for assessment and intervention of ACDs, that incorporate yarning and salient tasks, are likely to be more culturally appropriate and safe for Aboriginal and Torres Strait Islander peoples.More flexibility and guidance in the use of culturally and linguistically appropriate alternative assessment approaches are required in the National stroke guidelines for Aboriginal and Torres Strait Islander peoples.The adoption of enhanced models of culturally secure ACD service provision, that incorporate frequent SLP engagement with an Aboriginal or Torres Strait Islander support person during assessment and rehabilitation, are needed.There is an imperative for health professionals to actively account for culture and language difference in rehabilitation practices to ensure Indigenous peoples worldwide receive equitable and culturally-responsive services.

Exploring the Cognitive-Communication Challenges of Adults With Histories of Traumatic Brain Injury and Criminal Justice System Involvement: A Pilot Study

INTRODUCTION

The prevalence of traumatic brain injury (TBI) in the criminal justice system (CJS) is well known. Furthermore, the impact of TBI on communication has been well documented; however, no study has explored the communication challenges of those with TBI in the CJS or considered their implications within CJS contexts. Moreover, no study has examined the possible differences in communication between those with TBI and CJS history and those with TBI but no CJS history.

PURPOSE

This cross-sectional pilot study provides a preliminary exploration of the cognitive-communication challenges in a sample of adults with histories of TBI and CJS involvement compared with a sample of adults with histories of TBI but no CJS involvement.

METHOD

Eight individuals with histories of TBI and CJS involvement were recruited through community agencies. The La Trobe Communication Questionnaire (LCQ) was administered to collect self-reported data on perceived cognitive-communication abilities, including social communication behaviors. Findings were examined and then compared with a previously studied sample of 160 individuals with TBI. Logistic regressions were calculated to determine whether response scores on the LCQ would be predictive of group membership (i.e., TBI + CJS or TBI only).

RESULTS

A range of cognitive-communication challenges were reported by both groups. A logistic regression analysis demonstrated a reasonable inference that LCQ responses may predict group membership and support the potential for statistically significant and meaningful results to justify future studies.

CONCLUSIONS

These challenges have the potential to negatively impact the success of communication interactions within the CJS and illustrate a need for speech-language pathology services for individuals with TBI in the CJS. The nature and magnitude of between-group differences merits further investigation with larger samples to explore whether any specific cognitive-communication challenge is unique to, or predictive of, CJS involvement for purposes of targeted assessment and intervention.

Clinically Applicable Sociolinguistic Assessment for Cognitive-Communication Disorders

PURPOSE

The third International Cognitive-Communication Disorders Conference was held in early 2022, providing an opportunity for researchers and clinicians to discuss management of cognitive-communication disorders (CCDs). Presentations that addressed social discourse initiated broader conversations about implementing sociolinguistic methods in research and clinical contexts. Given the heterogeneity of CCDs and sociocultural contexts, a person-centered approach is needed. Sociolinguistic methods are inherently relevant and salient to the individual's communication context and partners. Sociolinguistic analyses provide information about language skills, cognitive-communication skills, and social cognition. The purpose of this article is to share a model of social communication and provide descriptions of current methods that can be used by researchers and clinicians to capture the complexity of social communication, thereby advancing our knowledge and practice.

CONCLUSION

Although there is a growing literature base that supports the inclusion of sociolinguistic methods, there remains a disconnect between the literature and clinical application that current researchers and practitioners have an opportunity to address.

Differences in pragmatic communication skills of adults with intellectual disabilities and dual diagnoses

INTRODUCTION

Pragmatics includes a set of skills related to language structure and meaning that allow the speaker to use the language appropriately and in accordance with different communication situations. The aim of this research was to determine the differences in pragmatic communication skills of adults with intellectual disabilities, dual diagnoses, and typical development, and to determine the effects of gender, age, the level of intellectual functioning and speech comprehension on their achievements on two assessment instruments.

METHODS

The sample included 180 adults (60 typically developing participants, 60 with intellectual disabilities, and 60 participants with dual diagnoses). We used two instruments to assess pragmatic communication skills - Communication Checklist - Adult, CC-A, and the Assessment Battery for Communication, ABaCo. In order to test the differences between the three groups of participants, we used canonical discriminant analysis.

RESULTS

Discriminant analysis revealed two significant canonical functions. Function one (speech comprehension and the level of intellectual disability, social engagement, and paralinguistic scale) differentiates between typically developing participants and participants with dual diagnoses the most. The second canonical function (language structure, linguistic scale, paralinguistic scale, extralinguistic scale, and context scale) differentiates between participants with intellectual disabilities and participants with dual diagnoses the most. According to the results, age did not affect pragmatic achievements.

DISCUSSION

Pragmatic skills are very complex, and different instruments measure different dimensions of these abilities. The results of this research lead to the conclusion that we can differentiate between the pragmatic abilities of typically developing people, people with intellectual disabilities, and those with dual diagnoses with the help of the ABaCo battery and the CC-A questionnaire.

Validation of Videoconference Administration of Picture Description From the Western Aphasia Battery-Revised in Neurotypical Canadian French Speakers

PURPOSE

During the COVID-19 pandemic, clinicians and researchers have increasingly used remote online assessments to pursue their activities, but mostly with tests not validated for videoconference administration. This study aims to validate the remote online administration of picture description in Canadian French neurotypical speakers and to explore the thematic unit (TU) checklist recently developed.

METHOD

Spoken discourse elicited through the picture description task of the Western Aphasia Battery-Revised (WAB-R) was collected from Canadian French neurotypical speakers from Québec aged between 50 and 79 years old. Forty-seven participants completed the task in person, and 49 participants completed the task by videoconference. Videos of each discourse sample were transcribed using CHAT conventions. Microstructural variables were extracted using the CLAN (Computerized Language ANalysis) program, whereas thematic informativeness was scored for each sample using TUs. Chi-square tests were conducted to compare both groups on each TU; t tests were also performed on the total score of TUs and microstructural variables.

RESULTS

Groups were matched on sex, age, and education variables. The t tests revealed no intergroup difference for the total TU score and for the microstructural variables (e.g., mean length of utterances and number of words per minute). Chi-square tests showed no significant intergroup difference for all 16 TUs.

CONCLUSIONS

These findings support remote online assessment of the picnic scene of the WAB-R picture description in Canadian French neurotypical speakers. These results also validate the 16 TUs most consistently produced. The use of videoconference could promote and improve the recruitment of participants who are usually less accessible, such as people using assistive mobility technologies.

Systematic Review of Discourse and Social Communication Interventions in Traumatic Brain Injury

PURPOSE

This study reviewed the current state of discourse and social communication interventions in traumatic brain injury (TBI) to provide clinically focused guidance about treatment efficacy, treatment approaches by TBI severity, treatment components, and treatment outcome measures.

METHOD

Searches were conducted in five electronic databases and reference lists of topical articles for discourse or social communication interventions in TBI published between 2012 and 2021. Search terms reflected three concepts: TBI, treatment, and cognitive-communication. Studies were evaluated for methodological quality using rating scales specific to study design.

RESULTS

Seven hundred sixty-seven records were identified, culminating in 21 studies for qualitative synthesis. All approaches resulted in improvement posttreatment, but durability and strength of evidence varied. Five treatment components were identified as "essential" for fostering change. Discourse approaches were generally more effective in mild-to-moderate TBI, whereas social communication approaches were more effective in moderate-to-severe TBI. Communication outcome measures were generally more sensitive to change than measures of other domains of functioning.

CONCLUSIONS

The evidence suggests that discourse and social communication treatments are promising for improving communication in TBI. Selection of treatment components and tailoring treatment to the individual are important clinical considerations. Use of at least two proximal outcome measures that evaluate the target behavior and extent of functional generalization may be advantageous. The field would benefit from additional, more rigorous treatment studies to provide a greater understanding of how best to treat cognitive-communicative impairments in people with TBI.

Die Erhebung von kommunikativ-pragmatischen Fähigkeiten und Lebensqualität nach Schädel-Hirn-Trauma

Zusammenfassung. Hintergrund: Kommunikationsstörungen nach Schädel-Hirn-Trauma (SHT) können die Betroffenen langfristig in der sozialen Teilhabe und damit in der Lebensqualität (LQ) beeinträchtigen. Der Erfassung dieser Störungen liegt aktuell kein einheitliches Vorgehen zugrunde. Ziele: Ziel des vorliegenden Scoping Reviews war die Erfassung von Diagnostikverfahren, welche die kommunikativ-pragmatischen Kompetenzen und die Auswirkung möglicher kommunikativer Defizite auf soziale Teilhabe und LQ bei Menschen mit SHT überprüfen. Ergebnisse: Eine systematische Datenbankrecherche für den Veröffentlichungszeitraum 2010 bis 2020 identifizierte 14 relevante Testverfahren (6 auf Deutsch verfügbar). Eine inhaltliche und methodische Analyse stellte Verfahren zur Überprüfung der Kommunikationsfähigkeit (z. B. La Trobe Communication Questionnaire [LCQ]) und Verfahren zur Erfassung von Partizipation und LQ (z. B. Quality of Life after Brain Injury [QOLIBRI]) heraus. Zusammenfassung: Trotz der hohen Auftretenshäufigkeit und Persistenz kommunikativer Störungen nach SHT stehen im deutschsprachigen Raum bislang wenige geeignete Diagnostikverfahren zur Ermittlung von Kommunikationsfähigkeiten und LQ zur Verfügung. Eine weiterführende Entwicklung erscheint unerlässlich.

Nonstandardized Assessment of Cognitive-Communication Abilities Following Pediatric Traumatic Brain Injury: A Scoping Review

Purpose The purpose of this study is to describe and synthesize existing research on nonstandardized assessment of cognitive-communication abilities in children with traumatic brain injury (TBI) in order to improve the detection, diagnosis, and tracking of injury sequelae and guide appropriate service provision. Materials and Method A search of peer-reviewed journal databases revealed 504 unique articles published between January 2000 and August 2019. For full inclusion, articles had to report on empirical studies examining variables related to the nonstandardized assessment of cognitive-communication skills following TBI in children. Review articles, expert opinion pieces, and non-English language articles were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guided this process. Results Results were tabulated for each of the 14 articles that met full inclusion criteria. Included studies presented five different types of nonstandardized assessment: discourse analysis (n = 3), systematic observation of child's performance during an instrumental activity of daily living (n = 4), virtual reality tasks (n = 3), structured cognitive tasks (n = 2), and functional rating scales (n = 2). The majority of included studies compared the outcomes of nonstandardized assessment against subtest scores and checklists drawn from a variety of existing standardized and criterion-referenced assessments. Targeted cognitive-communication skills included attention, working memory, self-regulation, planning, multitasking, social problem-solving, inferencing, and macrolevel discourse. Conclusions Preliminary research suggests that a well-designed and systematically implemented nonstandardized assessment can yield essential information about children's cognitive-communication abilities in real-world contexts. Further research is needed to validate these assessments and to determine in which settings and situations they may prove most effective.

The Cognitive-Communication Checklist for Acquired Brain Injury: A Means of Identifying, Recording, and Tracking Communication Impairments

Purpose The communication service needs of individuals with acquired brain injuries (ABIs) are frequently overlooked, leading to delays, denials, or premature discharge from communication interventions. This is particularly true for those with subtle cognitive-communication deficits, which may not be apparent until sufficiently challenged at work, in school, or in the community. The purpose of this study was to evaluate a referral tool that could promote understanding of the broad range of communication impairments that occur following ABI and lead to improved identification and referral. Method This study evaluated the Cognitive-Communication Checklist for Acquired Brain Injury (CCCABI) through a survey. The CCCABI is a referral tool that summarizes 45 communication difficulties in 10 areas of cognitive-communication functioning. One hundred sixteen speech-language pathologists, 34 multidisciplinary referral sources, and 41 individuals with lived experience of brain injury were surveyed to evaluate the utility of this referral tool. Results The need for such a referral tool was endorsed by 96% of speech-language pathology respondents, 91% of multidisciplinary respondents, and 100% of respondents with lived experience of brain injury. Responses supported the CCCABI as a clear, comprehensive, and accessible tool for education and identification of the communication impairments that can occur after ABI. Conclusion The CCCABI is a means of increasing understanding of communication service needs following ABI in a manner that is accessible to individuals, families, program designers, funding sources, administrators, and multidisciplinary referral sources.

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.

Expression of propositional attitudes in conversation by adults with traumatic brain injury: A relevance theoretic approach

BACKGROUND

Impairments in social communication are ubiquitous after moderate to severe traumatic brain injury (TBI). Most attempts to quantify these impairments have been descriptive rather than theoretically motivated. We propose that Relevance Theory provides a framework for characterizing social communication limitations after TBI and linking these problems to underlying cognitive impairments.

AIMS

This study asked how adult speakers with and without TBI used specific linguistic forms in social communication. We selected three linguistic markers that convey thoughts and feelings of the speaker and which are intended to influence the same in the listener: propositional attitude verbs, the discourse marker like and the quotative like.

METHODS & PROCEDURES

Ten adults with moderate to severe TBI and 12 healthy adults completed 5-min casual conversations with student researcher partners as part of a larger research study. Conversations were transcribed and analysed for the frequency of the three linguistic markers, corrected for total words in the transcript.

OUTCOMES & RESULTS

Participants in the TBI group used discourse marker like significantly less than participants in the healthy comparison group (0.75% and 2.06% of total words, respectively; p = 0.05, d = -0.43) and showed less variety in functions of like. The use of propositional attitude verbs and quotative like was not affected by TBI.

CONCLUSIONS & IMPLICATIONS

Expression of propositional attitude seems largely preserved after TBI. Relevance Theory may provide a helpful framework (1) to interpret subtle quantitative and qualitative differences that contribute to social conversation problems of adults with TBI; and (2) to elucidate relations among the social communication signs and symptoms and underlying cognitive impairments. What this paper adds What are the potential or actual clinical implications of this work? More awareness and understanding of how social cognition may look in everyday conversations, may help SLPs who treat patients with such difficulties as a result of TBI.

Profiling variability and development of spoken discourse in mainstream adolescents

Competence in spoken discourse is an important consideration during assessment and intervention planning for adolescents with communication difficulties. Currently, a lack of age-appropriate protocols and reference data against which to interpret performance, are barriers when working with this population, particularly those that assess a range of genre and language features. Using a new assessment tool, the Curtin University Discourse Protocol-Adolescent (CUDP-A), this study aimed to collect and describe spoken discourse samples from a large group of adolescents (n = 160), aged 12 to 15 years, recruited to represent a mainstream academic cohort. For each participant, samples of recount (n = 3), expository (n = 3), persuasive (n = 3), and narrative (n = 2) discourse were described using theoretically supported measurements sensitive to micro-linguistic, micro-structural, macro-structural, and super-structural discourse features. Participants also completed a standardized assessment of oral language. Variability was found in micro-linguistic and micro-structural features, with stability seen in macro-structural and super-structural features. Few age- and gender-related differences were observed, while multiple significant correlations between spoken discourse and oral language variables were revealed across the sample. The CUDP-A was successful in eliciting spoken discourse across genres relevant to social and academic contexts, enabling an in-depth description of adolescent discourse. This tool, supported by the reference data, provides a new opportunity to assess spoken discourse skills in adolescents from clinical populations, e.g., acquired brain injury or developmental disorders. Further research is needed to examine factors influencing discourse ability, such as those that may be related to genre, or contextual factors related to the presence of communication partners, with novel tools such as the CUDP-A facilitating this.

Description and Effectiveness of Communication Partner Training in TBI: A Systematic Review

OBJECTIVES

To evaluate the current evidence on communication partner training and its effectiveness on outcomes for people with traumatic brain injury (TBI) and/or their communication partners.

METHODS

Information sources: Systematic searches of 9 databases (AMED, CINAHL, EMBASE, Medline/EBSCOHOST, PsycINFO, PsycBITE, PsycARTICLES, PubMed, and Scopus) from database inception to February 2019. Eligibility criteria: Empirical studies on interventions for adult communication partners where the primary focus of the program (>50%) was on improving communication skills of people with TBI and/or communication partners. Data: Participants, characteristics of the training, outcome measures, and findings. Risk of bias: Standard checklists were used for methodological quality (PEDro, ROBiN-T) and intervention description (TIDieR). Synthesis: Narrative synthesis and effect sizes (Cohen's d) for group-level studies.

OUTCOMES

Ten articles (describing 8 studies) met eligibility criteria: 3 randomized controlled trials, 2 nonrandomized controlled trials, and 3 single-case experimental designs. Studies included a total of 258 people with TBI and 328 communication partners; however, all but one study had fewer than 65 participants. Methodological quality varied and intervention description was poor. Three studies in the final synthesis (n = 41 communication partners, n = 36 people with TBI) reported positive intervention effects. Effect sizes in group studies were d = 0.80 to 1.13 for TBI and d = 1.16 to 2.09 for communication partners.

CONCLUSIONS

The articles provided encouraging, though limited, evidence for training communication partners. Greater methodological rigor, more clearly described interventions, and consistent use of outcome measures and follow-up after treatment are needed. Further research on this topic is warranted.

Communication partner training in traumatic brain injury: a UK survey of Speech and Language Therapists' clinical practice

PRIMARY OBJECTIVE

To explore the clinical practice of communication partner training by Speech and Language Therapists for people with traumatic brain injury in the UK.

STUDY DESIGN

Online 97-item survey which addressed the practice of training both familiar and unfamiliar communication partners, and barriers and facilitators to implementation informed by the Theoretical Domains Framework.

PARTICIPANTS

169 Speech and Language Therapists from private and public settings in the UK.

RESULTS

While 96% reported training familiar communication partners, only 58% reported training unfamiliar communication partners. Therapists reported providing communication partner training consistent with best practice 43% of the time. Evidence-based published programmes were used by 13.8% and 19.9% of participants for training familiar and unfamiliar partners, respectively. Therapists reported using outcomes for familiar and unfamiliar communication partners 83% and 78% of the time. The most frequently reported barrier was lack of behavioral regulation (e.g., planning). Most frequent perceived facilitators were clinicians wanting to deliver communication partner training and that training was part of therapists' professional role (social professional role and identity).

CONCLUSIONS

Therapists were motivated to deliver communication partner training but reduced capability affected implementation. Further support to clinicians on outcome measurement with materials to develop workplace systems to monitor implementation is needed.

Improved Conversation Outcomes After Social Communication Skills Training for People With Traumatic Brain Injury and Their Communication Partners: A Clinical Trial Investigating In-Person and Telehealth Delivery

Purpose The aim of the study was to investigate the effectiveness of social communication skills training (TBIconneCT) for people with traumatic brain injury (TBI) and their communication partners, delivered in-person or via telehealth, on quality of conversations. Method This study is a clinical trial, including an in-person intervention group (n = 17), a telehealth intervention group (n = 19), and a historical control group (n = 15). Participants were adults at least 6 months post moderate-to-severe TBI with social communication skills deficits and their usual communication partners. Participants completed a casual and purposeful conversation task at pre-intervention, postintervention, and a follow-up assessment. A blinded assessor evaluated conversations using the Adapted Measure of Participation in Conversation and the Adapted Measure of Support in Conversation. Treatment effects were examined by comparing groups on change in ratings between pre- and posttraining. Maintenance of effects was examined using change between posttraining and follow-up assessment. The trial protocol was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12615001024538). Results Trained participants with TBI had significant improvements in participation in casual conversation compared to controls. Trained communication partners also had significant improvements compared to controls on ratings of support in casual conversations. However, treatment effects were not maintained at follow-up for two of eight measures. Comparisons between outcomes of in-person and telehealth groups found negligible to small effect sizes for six of eight measures. Conclusions The findings reinforce previous studies demonstrating the efficacy of communication partner training after TBI. Telehealth delivery produced similar outcomes to in-person delivery.
