Social Competence Treatment After Traumatic Brain Injury: A Multicenter, Randomized Controlled Trial of Interactive Group Treatment Versus Noninteractive Treatment

Cognitive communication disorders after brain injury: A systematic COSMIN review of measurement instruments

BACKGROUND

There is a lack of consensus on standardized measurement instruments (MIs) for the assessment of cognitive communication disorders in individuals with acquired brain injury (ABI).

OBJECTIVES

To identify and describe the currently available MIs for the assessment of cognitive communication disorders in individuals with ABI and to evaluate the psychometric properties of MIs.

METHODS

A search was conducted in 6 databases on March 12, 2024 using a validated methodological search filter. We included studies that evaluated psychometric properties of MIs used to assess cognitive communication disorders in individuals with ABI. We applied the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) to evaluate the psychometric properties of the MIs.

RESULTS

We included 48 records reporting on 44 MIs. Of all MIs, the La Trobe Communication Questionnaire (LCQ) and the St Andrew's-Swansea Neurobehavioural Outcome Scale (SASNOS) were studied most extensively. No MIs had undergone exhaustive methodological evaluation.

CONCLUSIONS

Based on the COSMIN, only 1 of 44 MIs can be recommended as its results can be trusted. Most MIs have the potential to be recommended but require further research to assess their psychometric quality. The development of new tools is not necessary but further methodological studies should be conducted on promising tools. This review may help clinicians and researchers to select an MI for the assessment of cognitive communication disorders and may facilitate diagnosis and research.

Family members' and friends' reports after standard and intensive group treatment for social communication difficulties following acquired brain injury - a mixed method approach

OBJECTIVE

To examine family members/friends' perception of change following standard and intensive group interactive structured treatment (GIST) for persons with social communication difficulties (SCDs).

METHODS

A parallel mixed methods design combining data from questionnaires, the Goal Attainment Scale, and interviews.

PARTICIPANTS

Forty-nine adult (>18 years) family members/friends (69.4% female) of persons with SCDs and acquired brain injury (ABI) (cohabitating partner, 53.1%; other relatives, 30.6%; friends, 16.3%).

INTERVENTION

Standard GIST consisted of 12 weekly outpatient sessions (2.5 h). Intensive GIST consisted of 4 weeks of inpatient rehabilitation (2 × 3 days/week, 2 × 4 days/week). Both treatments included 3- and 6-month follow-ups.

MAIN OUTCOME MEASURES

Quantitative measures (n = 49) included the following informant reports: Latrobe Communication Questionnaire (LCQ), Social Communication Skills Questionnaire-Adapted (SCSQ-A), Behavior Rating Inventory for Executive Functions-Adult version (BRIEF-A), and Goal Attainment Scale. The qualitative measure (n=9) was an interview performed at 6-month follow-up.

RESULTS

Converging results were found, suggesting a perceived positive change over time for both standard and intensive GIST, with no substantial differences reported between the treatments.

CONCLUSIONS

Family members/friends reported improved social communication skills of the persons with SCDs following standard and intensive GIST. However, the integration of data showed the complexity of assessing SCDs and the need for further investigation.

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.

INCOG 2.0 Guidelines for Cognitive Rehabilitation Following Traumatic Brain Injury, Part IV: Cognitive-Communication and Social Cognition Disorders

INTRODUCTION

Moderate to severe traumatic brain injury causes significant cognitive impairments, including impairments in social cognition, the ability to recognize others' emotions, and infer others' thoughts. These cognitive impairments can have profound negative effects on communication functions, resulting in a cognitive-communication disorder. Cognitive-communication disorders can significantly limit a person's ability to socialize, work, and study, and thus are critical targets for intervention. This article presents the updated INCOG 2.0 recommendations for management of cognitive-communication disorders. As social cognition is central to cognitive-communication disorders, this update includes interventions for social cognition.

METHODS

An expert panel of clinicians/researchers reviewed evidence published since 2014 and developed updated recommendations for interventions for cognitive-communication and social cognition disorders, a decision-making algorithm tool, and an audit tool for review of clinical practice.

RESULTS

Since INCOG 2014, there has been significant growth in cognitive-communication interventions and emergence of social cognition rehabilitation research. INCOG 2.0 has 9 recommendations, including 5 updated INCOG 2014 recommendations, and 4 new recommendations addressing cultural competence training, group interventions, telerehabilitation, and management of social cognition disorders. Cognitive-communication disorders should be individualized, goal- and outcome-oriented, and appropriate to the context in which the person lives and incorporate social communication and communication partner training. Group therapy and telerehabilitation are recommended to improve social communication. Augmentative and alternative communication (AAC) should be offered to the person with severe communication disability and their communication partners should also be trained to interact using AAC. Social cognition should be assessed and treated, with a focus on personally relevant contexts and outcomes.

CONCLUSIONS

The INCOG 2.0 recommendations reflect new evidence for treatment of cognitive-communication disorders, particularly social interactions, communication partner training, group treatments to improve social communication, and telehealth delivery. Evidence is emerging for the rehabilitation of social cognition; however, the impact on participation outcomes needs further research.

American Speech-Language-Hearing Association Clinical Practice Guideline: Cognitive Rehabilitation for the Management of Cognitive Dysfunction Associated With Acquired Brain Injury

BACKGROUND

Cognitive-communication impairments following acquired brain injury (ABI) can have devastating effects on a person's ability to participate in community, social, vocational, and academic preinjury roles and responsibilities. Guidelines for evidence-based practices are needed to assist speech-language pathologists (SLPs) and other rehabilitation specialists in the delivery of cognitive rehabilitation for the adult population.

PURPOSE

The American Speech-Language-Hearing Association, in conjunction with a multidisciplinary panel of subject matter experts, developed this guideline to identify best practice recommendations for the delivery of cognitive rehabilitation to adults with cognitive dysfunction associated with ABI.

METHOD

A multidisciplinary panel identified 19 critical questions to be addressed in the guideline. Literature published between 1980 and 2020 was identified based on a set of a priori inclusion/exclusion criteria, and main findings were pooled and organized into summary of findings tables. Following the principles of the Grading of Recommendations Assessment, Development and Evaluation Evidence to Decision Framework, the panel drafted recommendations, when appropriate, based on the findings, overall quality of the evidence, balance of benefits and harms, patient preferences, resource implications, and the feasibility and acceptability of cognitive rehabilitation.

RECOMMENDATIONS

This guideline includes one overarching evidence-based recommendation that addresses the management of cognitive dysfunction following ABI and 11 subsequent recommendations focusing on cognitive rehabilitation treatment approaches, methods, and manner of delivery. In addition, this guideline includes an overarching consensus-based recommendation and seven additional consensus recommendations highlighting the role of the SLP in the screening, assessment, and treatment of adults with cognitive dysfunction associated with ABI. Future research considerations are also discussed.

Each Systematic Review Brief summarizes the evidence on a theme related to a systematic review topic. This Systematic Review Brief presents findings from the systematic review on education and skills training interventions that address psychosocial, behavioral, and emotional skills for people with traumatic brain injury (TBI).

Goal attainment scaling as an outcome measure for randomised controlled trials: a scoping review

OBJECTIVES

(1) Identify the healthcare settings in which goal attainment scaling (GAS) has been used as an outcome measure in randomised controlled trials. (2) Describe how GAS has been implemented by researchers in those trials.

DESIGN

Scoping review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews approach.

DATA SOURCES

PubMed, CENTRAL, EMBASE and PsycINFO were searched through 28 February 2022.

ELIGIBILITY CRITERIA

English-language publications reporting on research where adults in healthcare settings were recruited to a randomised controlled trial where GAS was an outcome measure.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers completed data extraction. Data collected underwent descriptive statistics.

RESULTS

Of 1,838 articles screened, 38 studies were included. These studies were most frequently conducted in rehabilitation (58%) and geriatric medicine (24%) disciplines/populations. Sample sizes ranged from 8 to 468, with a median of 51 participants (IQR: 30-96). A number of studies did not report on implementation aspects such as the personnel involved (26%), the training provided (79%) and the calibration and review mechanisms (87%). Not all trials used the same scale, with 24% varying from the traditional five-point scale. Outcome attainment was scored in various manners (self-report: 21%; observed: 26%; both self-report and observed: 8%; and not reported: 45%), and the calculation of GAS scores differed between trials (raw score: 21%; T score: 47%; other: 21%; and not reported: 66%).

CONCLUSIONS

GAS has been used as an outcome measure across a wide range of disciplines and trial settings. However, there are inadequacies and inconsistencies in how it has been applied and implemented. Developing a cross-disciplinary practical guide to support a degree of standardisation in its implementation may be beneficial in increasing the reliability and comparability of trial results.

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.

Lifetime history of traumatic brain injury is associated with increased loneliness in adults: A US nationally representative study

BACKGROUND/OBJECTIVES

An estimated 55 million individuals worldwide live with chronic disability associated with traumatic brain injury (TBI), which may include cognitive, behavioral, and social impairments. Reduced participation in social activities is common after TBI; however, few studies have evaluated loneliness among survivors of TBI. The current study aimed to evaluate the association between history of TBI and loneliness and to identify mediators of this association.

METHODS/DESIGN

Retrospective cohort study. Nationally representative sample of N = 724 adults over age 50 years (Health and Retirement Study). Loneliness was evaluated using the 11-item Revised University of California Los Angeles (R-UCLA) Loneliness Scale (range 11-33). Lifetime history of TBI evaluated retrospectively using the Ohio State University TBI Identification Method. We included the following covariates: age, sex, race, and education; and mediators: depressive symptoms, number of comorbidities, chronic pain, difficulty with activities of daily living, and social network index.

RESULTS

History of TBI was associated with a 1.28-point (95% CI, 0.46-2.11; P < .05; Cohen's D = 0.284) increase in R-UCLA Loneliness Scale scores after covariate adjustment. Individuals with more recent injuries (within 10 years) and multiple lifetime TBIs reported the highest loneliness scores. In the structural equation model, depressive symptoms partially mediated the relationship between TBI and loneliness. All models were adjusted for US population sampling weights.

CONCLUSIONS

History of TBI was associated with greater loneliness compared with individuals without TBI in a representative sample of US adults. Managing depressive symptoms and medical consequences of TBI may be a target to ameliorate reporting of loneliness in this population.

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.

Intensive and standard group-based treatment for persons with social communication difficulties after an acquired brain injury: study protocol for a randomised controlled trial

INTRODUCTION

Social communication difficulties (SCDs) occur frequently after an acquired brain injury (ABI) and have disabling consequences, but effective interventions are scant. Group Interactive Structured Treatment (GIST) is a holistic group treatment targeting SCD that has received empirical support.

OBJECTIVE

To determine the efficacy of two GIST protocols, standard GIST and a newly developed intensive GIST, comparing standard GIST results to a wait-list control group (WL), as well as to intensive GIST received by participants following WL. The within subject results for WL and intensive GIST will also be examined.

METHODS AND ANALYSIS

Sixty adults (18-75 years) with SCD after ABI will be recruited for this randomised controlled trial. Standard GIST (n=30) will be delivered via outpatient sessions for 2.5 hours once per week for 12 weeks, plus one initial orientation session. Participants will be assessed at preintervention and postintervention and at 3-month and 6-month follow-ups (T1-T4). Intensive GIST (n=30) participants will be admitted to an inpatient rehabilitation unit for 4 weeks (two times 3 days/week, two times 4 days/week) and receive full-day sessions each week. Those participants will complete four assessments (T1-T4) in 12-week intervals as part of WL, assessments preintensive and postintensive GIST and at 3-month and 6-month follow-ups (T4-T7). The primary outcome measure is the La Trobe Questionnaire (self-report). Secondary outcome measures include the Profile of Pragmatic Impairment in Communication, a test of emotion recognition, the Goal Attainment Scale and questionnaires addressing social, emotional and cognitive functions, self-efficacy and quality of life.

ETHICS AND DISSEMINATION

Results will be communicated through international, peer-reviewed and popular science journals and presentations at scientific conferences. The study is approved by the Regional Committees for Medical and Health Research Ethics Norway (2017/1360). The trial will be conducted in accordance with the Declaration of Helsinki and reported in accordance with the Consolidated Standards of Reporting Trials 2010 statement and Standard Protocol Items: Recommendations for Interventional Trials recommendations.
