Using Conversation Analysis to Assess and Treat People with Aphasia

Conversation Analysis of Texting Exchanges in Aphasia

PURPOSE

Conversation analysis (CA) is an established method that has been used to understand how aphasia impacts the conversational success of individuals with aphasia (IWAs) and their conversation partners. This article demonstrates CA as a valuable analytic tool for studying text messaging in aphasia to better understand the specific co-constructed actions of IWAs and their partners as they engage in this communication modality.

METHOD

CA was applied to transcribed text message data from eight IWAs. Conversational structures present in face-to-face interactions were identified, segmented, and explicated with a focus on how IWAs and their partners negotiate interaction in this medium.

RESULTS

Three key elements of CA, namely, sequential organization, repair, and topic negotiation, were identified within the texting exchanges of participants and their texting partners and compared with existing CA studies on electronic messaging in adults without brain injury.

CONCLUSIONS

Findings suggest a multitude of strategies that IWAs and their partners used to meet both transactional and interactional goals of communication. Understanding gained from applying CA to texting in aphasia can inform the development of interventions that improve access to digital communication for IWAs.

A bibliometrix-based visualization analysis of international studies on conversations of people with aphasia: Present and prospects

In recent years, there has been a rapid increase in the number of people with aphasia due to brain lesions worldwide, which has prompted researchers to carry out in-depth studies on the pathogenesis, inducement and prognosis of aphasia from neurology, clinical medicine, psychology and other disciplines. With the deepening of research and understanding of aphasia, it is generally believed that a single discipline can no longer meet the needs of the academic community. Therefore, multidisciplinary integration has emerged and achieved fruitful results. This paper, based on the biblioshiny package run by R, conducts bibliometric analysis on the international interdisciplinary research status of conversation and aphasia, predicts its future development direction, and provides reference for relevant domestic research from international source journals. The results indicate that led by Australia, the United Kingdom, the United States and other countries, the international conversational aphasia research has formed a complete system, and formed a "descriptive study of patients with language disorders" and "applied study of rehabilitation treatment". In the future, while continuing to focus on these two categories of research, the empathy ability of conversational partners and medical staff may be taken into account, in order to better contribute to improving patients' quality of life.

Toward Neurodiversity: How Conversation Analysis Can Contribute to a New Approach to Social Communication Assessment

PURPOSE

The purpose of this clinical focus article was to illustrate the potential of employing conversation analysis (CA) as a method for assessing social communication that is neurodiversity affirming.

METHOD

This clinical focus article will provide an overview of CA and explain how it offers a theoretically grounded means of analyzing autistic children's everyday social interactions. Our aim is not simply to add a new assessment instrument to the disciplinary toolbox but to use the occasion to spur a reconsideration of how social communicative competence is currently conceptualized in the field and how those assumptions are reified through assessment practices. We will present a case illustration of a bilingual autistic child and his family. We will discuss the implications of a CA-informed assessment for reconceptualizing autistic social communicative competence.

RESULTS

The case study illustrates the contributions of CA for (a) shifting the focus of assessment from social communication as an individual skill to social communication as an interactional achievement and (b) surfacing social communicative competencies that may be dismissed as pathologies.

CONCLUSIONS

CA offers a relational understanding of autistic communication and sociality that is compatible with a critical stance on disability. Insights from CA problematize deeply entrenched notions of autism and social communication in speech-language pathology.

Conversation as an Outcome of Aphasia Treatment: A Systematic Scoping Review

PURPOSE

Conversation-focused speech-language pathology services are a top priority for people living with aphasia, but little is known about how researchers measure conversation as an outcome of treatment. This scoping review was undertaken to systematically review the evidence regarding the measurement of conversation in aphasia studies and to identify current practices and existing gaps.

METHOD

A systematic literature search was conducted for studies published between January 1995 and September 2019 in multiple electronic databases. Covidence software was used to manage search results, study selection, and data charting processes. Data were extracted from each study and then collated and organized to elucidate the breadth of approaches, tools, or procedures oriented to measuring conversation as an outcome and identify gaps in the existing literature.

RESULTS

The systematic search of the literature resulted in 1,244 studies. A total of 64 studies met inclusion criteria and were included in the review. The review summarizes the various tools and procedures used to measure conversation as an outcome of aphasia intervention, including variations in data collection and analysis procedures. The review also evaluates the quality of conversation measures in terms of psychometric properties and informal measures of validity. There was a total of 211 measures used across the 64 studies.

CONCLUSIONS

While there was no clear measure that was objectively superior, several measures show promise and warrant future exploration. Some of the orientations, conceptualizations, and procedures we have presented can be seen as options that might be included in a future conversation-focused core outcome set.

New perspectives, theory, method, and practice: Qualitative research and innovation in speech-language pathology

Purpose: Research in speech-language pathology has been dominated by experimental, empirical, and scientific approaches, which build on hypothesis testing and logical, deductive reasoning. Qualitative approaches stem from a different paradigm or world view which imply different questions and methodologies which, for example, emphasise codesign, reciprocity, individual experience and context. This article explores the relationship between qualitative inquiry in the field of speech-language pathology and innovation. It aims to show how the aspirations of the profession can be supported, and how innovation can be achieved, through research which sheds light on the lived experiences and perceptions of clients and families and builds an understanding of how they function in their everyday contexts.Method: We summarise qualitative approaches in speech-language pathology, explain the notion of innovation, and review qualitative research as a source of theoretical, methodological, and practice innovation in speech-language pathology.Result: Not only has qualitative inquiry underpinned examples of theoretical, methodological and practice innovations in speech-language pathology, but it can also play a part in enhancing translation and implementation of research innovations.Conclusion: An explicit consideration of what we mean by innovation is useful for speech-language pathologists. Qualitative research complements other forms of research in the field and has prompted new theoretical understandings, new methodologies and methods of research, and new ways to deliver our services in ways that are responsive to our clients and communities.

What is Functional Communication? A Theoretical Framework for Real-World Communication Applied to Aphasia Rehabilitation

Aphasia is an impairment of language caused by acquired brain damage such as stroke or traumatic brain injury, that affects a person’s ability to communicate effectively. The aim of rehabilitation in aphasia is to improve everyday communication, improving an individual’s ability to function in their day-to-day life. For that reason, a thorough understanding of naturalistic communication and its underlying mechanisms is imperative. The field of aphasiology currently lacks an agreed, comprehensive, theoretically founded definition of communication. Instead, multiple disparate interpretations of functional communication are used. We argue that this makes it nearly impossible to validly and reliably assess a person’s communicative performance, to target this behaviour through therapy, and to measure improvements post-therapy. In this article we propose a structured, theoretical approach to defining the concept of functional communication. We argue for a view of communication as “situated language use”, borrowed from empirical psycholinguistic studies with non-brain damaged adults. This framework defines language use as: (1) interactive, (2) multimodal, and (3) contextual. Existing research on each component of the framework from non-brain damaged adults and people with aphasia is reviewed. The consequences of adopting this approach to assessment and therapy for aphasia rehabilitation are discussed. The aim of this article is to encourage a more systematic, comprehensive approach to the study and treatment of situated language use in aphasia.

Spoken Discourse Assessment and Analysis in Aphasia: An International Survey of Current Practices

Purpose Spoken discourse analysis is commonly employed in the assessment and treatment of people living with aphasia, yet there is no standardization in assessment, analysis, or reporting procedures, thereby precluding comparison/meta-analyses of data and hindering replication of findings. An important first step is to identify current practices in collecting and analyzing spoken discourse in aphasia. Thus, this study surveyed current practices, with the goal of working toward standardizing spoken discourse assessment first in research settings with subsequent implementation into clinical settings. Method A mixed-methods (quantitative and qualitative) survey was publicized to researchers and clinicians around the globe who have collected and/or analyzed spoken discourse data in aphasia. The survey data were collected between September and November 2019. Results Of the 201 individuals who consented to participate, 189 completed all mandatory questions in the survey (with fewer completing nonmandatory response questions). The majority of respondents reported barriers to utilizing discourse including transcription, coding, and analysis. The most common barrier was time (e.g., lack of time). Respondents also indicated that there was a lack of, and a need for, psychometric properties and normative data for spoken discourse use in the assessment and treatment of persons with aphasia. Quantitative and qualitative results are described in detail. Conclusions The current survey study evaluated spoken discourse methods in aphasia across research and clinical settings. Findings from this study will be used to guide development of process standardization in spoken discourse and for the creation of a psychometric and normative property database.

Interactional practices in person-centred care: Conversation analysis of nurse-patient disagreement during self-management support

Background

Person‐centred care implies a change in interaction between care professionals and patients where patients are not passive recipients but co‐producers of care. The interactional practices of person‐centred care remain largely unexplored.

Objective

This study focuses on the analysis of disagreements, which are described as an important part in the co‐production of knowledge in interaction.

Design

A qualitative exploratory study using conversation analysis.

Setting and participants

Data were collected from a nurse‐led person‐centred intervention in a hospital outpatient setting. Interactions between adult patients with irritable bowel syndrome (n = 17) and a registered nurse were audio‐recorded. COREQ guidelines were applied.

Results

Disagreements were found after demonstration of the nurse's or patients’ respective professional or personal knowledge. Disagreements were also evident when deciding on strategies for self‐management. Although negotiations between opposing views of the nurse and patient were seen as important, the patient generally claimed final authority both in knowing how IBS is perceived and in the right to choose self‐management strategies. The nurse generally oriented towards patient authority, but instances of demonstration of nurse authority despite patient resistance were also found.

Discussion and conclusions

This study provides information on how co‐production of knowledge and decisions occur in the context of a person‐centred care intervention. Negotiations between nurse and patient views require a flexible approach to communication, adapting interaction to each context while bearing in mind the patients having the final authority. To facilitate co‐production, the patient's role and responsibilities in interaction should be explicitly stated.

Standardizing Assessment of Spoken Discourse in Aphasia: A Working Group With Deliverables

Purpose The heterogeneous nature of measures, methods, and analyses reported in the aphasia spoken discourse literature precludes comparison of outcomes across studies (e.g., meta-analyses) and inhibits replication. Furthermore, funding and time constraints significantly hinder collecting test-retest data on spoken discourse outcomes. This research note describes the development and structure of a working group, designed to address major gaps in the spoken discourse aphasia literature, including a lack of standardization in methodology, analysis, and reporting, as well as nominal data regarding the psychometric properties of spoken discourse outcomes. Method The initial initiatives for this working group are to (a) propose recommendations regarding standardization of spoken discourse collection, analysis, and reporting in aphasia, based on the results of an international survey and a systematic literature review and (b) create a database of test-retest spoken discourse data from individuals with and without aphasia. The survey of spoken discourse collection, analysis, and interpretation procedures was distributed to clinicians and researchers involved in aphasia assessment and rehabilitation from September to November 2019. We will publish survey results and recommend standards for collecting, analyzing, and reporting spoken discourse in aphasia. A multisite endeavor to collect test-retest spoken discourse data from individuals with and without aphasia will be initiated. This test-retest information will be contributed to a central site for transcription and analysis, and data will be subsequently openly curated. Conclusion The goal of the working group is to create recommendations for field-wide standards in methods, analysis, and reporting of spoken discourse outcomes, as has been done across other related disciplines (e.g., Consolidated Standards of Reporting Trials, Enhancing the Quality and Transparency of Health Research, Committee on Best Practice in Data Analysis and Sharing). Additionally, the creation of a database through our multisite collaboration will allow the identification of psychometrically sound outcome measures and norms that can be used by clinicians and researchers to assess spoken discourse abilities in aphasia.

Right hemisphere damage and other-initiated repair in everyday conversation

Right hemisphere damage causes communication problems in conversation, but its precise effects have been challenging to study. As such, there are few clinical assessments focused on right hemisphere damage and conversation, and essentially no evidence-based interventions. Other-initiated repair sequences (i.e. moments when a problem of hearing or understanding are indicated and addressed) are a well-described aspect of interaction, with a large body of empirical research evidencing their organisation. Because of the communicative activities they implicate, these sequences may also be a site in which the symptoms of right hemisphere communication disorder become salient. This study explores the organisation of other-initiated repair sequences in interactions involving people with right hemisphere communication disorder using conversation analysis. Two people with right hemisphere communication disorder caused by stroke and four of their familiar conversation partners were recorded in triadic interactions; 104 minutes of recordings were collected, and 28 other-initiated repair sequences were subjected to analysis. This included other-initiations of repair produced by participants with right hemisphere communication disorder, and other-initiations of repair addressed to them. Participants with right hemisphere communication disorder were found to implement efficacious other-initiations of repair, to recognise core aspects of the trouble sources indicated in their own turns, and to design suitable repair solutions. That is, their inferences about communication problems were successful. However, one participant with right hemisphere communication disorder displayed difficulty managing aspects of the repair sequences, with her conversation partners also orienting towards her difficulties. It is argued that her difficulties were driven by problems dealing with multifaceted and ambiguous conversational moments. These observed difficulties suggest that other-initiated repair sequences may be valuable for detecting right hemisphere communication disorder, and highlight the possible role of conversational sampling in clinical assessment.

How is right hemisphere communication disorder disabling? Evidence from response mobilizing actions in conversation

Aim: Assessment and intervention strategies for communication disorders caused by right hemisphere stroke are at an early stage of development. There is also little evidence on how right hemisphere communication disorder is disabling for everyday life. This study explores how a woman with conversational problems following right hemisphere stroke participated in everyday conversation with family members.Method: One hour of triadic conversation was recorded and analyzed using the descriptive qualitative methodology of conversation analysis. It focused on attempts by the woman with right hemisphere stroke to direct conversation with "response mobilizing" communicative acts, i.e., communicative acts that set out clear expectations about who should speak, and how they should respond.Results: Seventy-eight communicative acts produced by the woman with right hemisphere communication disorder were divided into five groupings based on how her conversation partners addressed them. Around half of her response mobilizing communicative acts received unsupportive responses from her conversation partners, including minimal acknowledgements, explicit rejections, and ignoring responses.Conclusion: The findings of this study provide novel insight into the ways that right hemisphere communication disorder affects routine communication, and the nature of the disability it causes. This information will support the future development of evidence-based speech pathology assessment and intervention for right hemisphere stroke.IMPLICATIONS FOR REHABILITATIONRight hemisphere stroke can have complex implications for communication, but little is known about how they manifest in daily life.Familiar communication partners may deal with troublesome communicative acts in conversation by preventing them from developing, which may be useful information for speech pathology assessment.Speech pathologists should consider sampling everyday conversation because it can provide insight into the ways that communication disorders caused by right hemisphere stroke restrict participation in daily life.

Facilitator Behaviors Leading to Engagement and Disengagement in Aphasia Conversation Groups

Purpose Researchers have identified features of successful aphasia conversation groups and clinician behaviors leading to engagement and group cohesion. There has been less focus in the literature on facilitator behaviors that hinder participation or result in disengagement. This study aims to explore the behaviors of graduate student facilitators that contribute to and detract from engagement in aphasia conversation groups. Method Data were drawn from 4 conversation group sessions from 2 different university settings. Groups included 1 graduate student facilitator and 3 or more persons with aphasia. Sociolinguistic discourse analysis was applied to transcripts of group sessions. Results Three broad patterns detailing facilitator behaviors were identified. Several facilitator actions contributing to engagement were noted, including strategic use of topic elicitors, multimodal communication supports, and techniques to avoid interactional asymmetry. Behaviors associated with participant disengagement were also noted across sessions, including restricted discourse behaviors and difficulty managing the competing needs of participants. Engagement and disengagement were the product of several coordinating actions of the facilitator and group members that together influenced participation in conversation. Conclusion Results suggest that novice facilitators exhibit behaviors that contribute to and detract from participant engagement in aphasia conversation groups. Findings, discussed within the context of the literature on well-managed groups, highlight the skill required in managing the needs of participants with aphasia and knowing how and when to employ clinician-led strategies.

Conversational trouble and repair in dementia: Revision of an existing coding framework

A decline in the effectiveness of everyday conversation is often observed for people with dementia. This study explored conversational trouble and repair between people with dementia residing in residential care and professional care staff. The aim was to examine the utility of an existing conversational trouble and repair framework by Watson, Carter and Chenery (1999) in a comparatively larger sample. Twenty conversations were coded for dementia-specific trouble and repair; however, the original framework could not adequately accommodate the variety of trouble and repair within the dataset. The data was subsequently used to inform a revised framework, which captures a wide spectrum of trouble and repair in dementia and offers more precise codes to researchers and clinicians working with this clinical population. Examples of divergent coding strategies between the original and revised framework are provided as well as examples of trouble and repair patterns observed in both carers and people with dementia.

Humour in clinical-educational interactions between graduate student clinicians and people with aphasia

BACKGROUND

During clinical interactions, clinicians and people with aphasia (PWA) use humour and laughter for a range of purposes, most of which contribute to friendly interactions in which the participants appear to develop a positive regard for one another. Moreover, humour is a vital component of facework, or the processes interactants engage in to protect their own and one another's well-respected, public personas.

AIMS

To examine the ways in which speech-language pathology graduate student clinicians enlist humour during one-on-one therapy sessions for PWA.

METHODS & PROCEDURES

Three dyads composed of one graduate student clinician and one person with aphasia acted as participants. We recorded six routine individual aphasia therapy sessions that were each about 60 min in length. All sessions were orthographically transcribed by a trained research assistant. Transcriptions included verbal and non-speech communication (e.g., facial expressions, gestures, writing). For analysis, we employed an ethnographic microanalysis framework. First, by focusing on laughter produced by the interactants, we identified segments in the data that involved clinician-led humour. Next, we sought to understand patterns that represented potential functions of humour. We consciously sought out instances that did not appear consistent with our developing understanding of the functions of humour. Such negative cases were used to refine our description of how graduate student clinicians use humour. Other verification procedures included member checking and peer debriefing.

OUTCOMES & RESULTS

The findings illustrate that graduate student clinicians use laughter and humour for a range of interactional purposes when interacting with clients with aphasia. Humour was used as a means of (1) softening exposure to client's errors, (2) equalizing interactional power, (3) mitigating errors made by graduate student clinicians, (4) supporting own narrative production and (5) demonstrating affiliation.

CONCLUSIONS & IMPLICATIONS

The current study demonstrates that graduate student clinicians we observed, like the clinicians studied in previous investigations of humour in therapeutic encounters, possess the humour and laughter-related skills that help to foster positive interactions with PWA. Future investigations of the source of these skills should determine if students are adept because of natural abilities or if students can be taught to be better interactants via instruction. Findings emanating from these studies can be used to inform curriculum design, which will in turn help our field better meet the needs of clients.

A staff training intervention to improve communication between people living with dementia and health-care professionals in hospital: the VOICE mixed-methods development and evaluation study

Background

Twenty-five per cent of hospital beds are occupied by a person living with dementia. Dementia affects expressive communication and understanding. Health-care professionals report a lack of communication skills training.

Objectives

To identify teachable, effective strategies for communication between health-care professionals and people living with dementia, and to develop and evaluate a communication skills training course.

Design

We undertook a systematic literature review, video-recorded 41 encounters between staff and people with dementia, and used conversation analysis to investigate communication problems and solutions. We designed a communication skills training course using coproduction and multiple pedagogic approaches. We ran a pilot, followed by six courses for health-care professionals. We measured knowledge, confidence and communication behaviours before, immediately after and 1 month after the course, and undertook interviews with participants and managers. Behaviours were measured using blind-rated videos of simulations.

Setting

General hospital acute geriatric medical wards and two hospital clinical skills centres.

Participants

We video-recorded 26 people with dementia and 26 professionals. Ten experts in dementia care, education, simulation and communication contributed to intervention development. Six health-care professionals took part in a pilot course, and 45 took part in the training.

Results

The literature review identified 26 studies describing 10 communication strategies, with modest evidence of effectiveness. Health-care professional-initiated encounters followed a predictable phase structure. Problems were apparent in requests (with frequent refusals) and in closings. Success was more likely when requests were made directly, with high entitlement (authority to ask) and with lowered contingencies (made to sound less difficult, by minimising the extent or duration of the task, asking patients ‘to try’, offering help or proposing collaborative action). Closings were more successful if the health-care professional announced the end of the task, made a specific arrangement, body language matched talk, and through use of ‘closing idioms’. The training course comprised 2 days, 1 month apart, using experiential learning, including lectures, video workshops, small group discussions, simulations (with specially trained actors) and reflections. We emphasised the incorporation of previous expertise and commitment to person-centred care. Forty-four participants returned for the second training day and 43 provided complete evaluation data. Knowledge and confidence both increased. Some behaviours, especially relating to closings, were more commonly used after training. The course was rated highly in interviews, especially the use of simulations, real-life video clips and interdisciplinary learning. Participants reported that they found the methods useful in practice and were using them 1 month after the course finished.

Limitations

Data were from people with moderate to severe dementia, in an acute hospital, during health-care professional-initiated interactions. Analysis was limited to problems and solutions that were likely to be ‘trainable’. Actors required careful preparation to simulate people with dementia. Communication skills training course participants were volunteers, unlikely to be representative of the general workforce, who displayed high levels of baseline knowledge, confidence and skills. Before-and-after evaluations, and qualitative interviews, are prone to bias.

Conclusions

Requests and closings pose particular difficulties for professionals communicating with people with dementia. We identified solutions to these problems and incorporated them into communication skills training, which improved knowledge, confidence and some communication behaviours. Simulation was an effective training modality.

Future work

Further research should investigate a wider range of health, social care and family carers. Conversation analysis should be used to investigate other aspects of health-care communication.

Using conversation analysis to inform role play and simulated interaction in communications skills training for healthcare professionals: identifying avenues for further development through a scoping review

BACKGROUND

This paper responds to previously published debate in this journal around the use of sociolinguistic methods in communication skills training (CST), which has raised the significant question of how far consultations with simulated patients reflect real clinical encounters. This debate concluded with a suggestion that sociolinguistic methods offer an alternative analytic lens for evaluating CST. We demonstrate here that the utility of sociolinguistic methods in CST is not limited to critique, but also presents an important tool for development and delivery.

METHODS

Following a scoping review of the use of role play and simulated interaction in CST for healthcare professionals, we consider the use of the specific sociolinguistic approach of conversation analysis (CA), which has been applied to the study of health communication in a wide range of settings, as well as to the development of training.

DISCUSSION

Role play and simulated interaction have been criticised by both clinicians and sociolinguists for a lack of authenticity as compared to real life interactions. However they contain a number of aspects which healthcare professionals report finding particularly useful: the need to think on one's feet in real time, as in actual interaction with patients; the ability to receive feedback on the simulation; and the ability to watch and reflect on how others approach the same simulation task in real time. Since sociolinguistic approaches can help to identify inauthenticity in role play and simulation, they can also be used to improve authenticity. Analysis of real-life interactions using sociolinguistic methods, and CA in particular, can identify actual interactional practices that are used by particular patient groups. These practices can then be used to inform the training of actors simulating patients. In addition, the emphasis of CA on talk as joint activity means that proper account can be taken of the way in which simulated interaction is co-constructed between simulator and trainee. We suggest that as well as identifying potential weaknesses in current role play and simulation practice, conversation analysis offers the potential to enhance and develop the authenticity of these training methods.

Interaction-focussed therapy for aphasia: Effects on communication and quality of life

PURPOSE

This study examined the effects of an interaction-focussed therapy for aphasia, which involved both people with aphasia and their familiar conversation partners. It was hypothesised the interaction-focussed therapy would lead to positive changes in targeted conversation behaviours, and improved quality of life for participants with aphasia.

METHOD

Three people with chronic aphasia and three of their familiar conversation partners completed an 8-week interaction-focussed therapy programme. A series of single case multiple-baseline ABA experiments were conducted. Outcome measures focussed on changes in targeted behaviours between pre- and post-therapy conversation samples, and changes in quality of life.

RESULT

All participant dyads improved their conversations. Familiar conversation partners demonstrated significant changes in targeted behaviours, while only one participant with aphasia achieved significant improvements. There was little evidence of a positive impact on quality of life for participants with aphasia.

CONCLUSION

Interaction-focussed therapy enhances everyday communication for people with aphasia and their conversation partners. However, the complex nature of learning in this intervention means that further, likely interdisciplinary work is required to better understand what mediates skill acquisition and therapeutic change and its psychosocial impact. This information is particularly important for optimising interaction-focussed therapy for people with aphasia.

The VOICE study - A before and after study of a dementia communication skills training course

Background

A quarter of acute hospital beds are occupied by persons living with dementia, many of whom have communication problems. Healthcare professionals lack confidence in dementia communication skills, but there are no evidence-based communication skills training approaches appropriate for professionals working in this context. We aimed to develop and pilot a dementia communication skills training course that was acceptable and useful to healthcare professionals, hospital patients and their relatives.

Methods

The course was developed using conversation analytic findings from video recordings of healthcare professionals talking to patients living with dementia in the acute hospital, together with systematic review evidence of dementia communication skills training and taking account of expert and service-user opinion. The two-day course was based on experiential learning theory, and included simulation and video workshops, reflective diaries and didactic teaching. Actors were trained to portray patients living with dementia for the simulation exercises. Six courses were run between January and May 2017. 44/45 healthcare professionals attended both days of the course. Evaluation entailed: questionnaires on confidence in dementia communication; a dementia communication knowledge test; and participants’ satisfaction. Video-recorded, simulated assessments were used to measure changes in communication behaviour.

Results

Healthcare professionals increased their knowledge of dementia communication (mean improvement 1.5/10; 95% confidence interval 1.0–2.0; p<0.001). Confidence in dementia communication also increased (mean improvement 5.5/45; 95% confidence interval 4.1–6.9; p<0.001) and the course was well-received. One month later participants reported using the skills learned in clinical practice. Blind-ratings of simulated patient encounters demonstrated behaviour change in taught communication behaviours to close an encounter, consistent with the training, but not in requesting behaviours.

Conclusion

We have developed an innovative, evidence-based dementia communication skills training course which healthcare professionals found useful and after which they demonstrated improved dementia communication knowledge, confidence and behaviour.

Comparing linguistic complexity and efficiency in conversations from stimulation and conversation therapy in aphasia

BACKGROUND

Efficacy studies have demonstrated the benefit of group conversation therapy for a person with aphasia (PWA). However, a PWA typically participates in individual therapy prior to group therapy. Stimulation therapy (ST) is the most common type of individual aphasia therapy. Ultimately, the outcome of therapy is to enable the PWA to communicate effectively with others, which suggests the need for conversation therapy (CT). Little efficacy data exist to demonstrate the benefit of CT between a PWA and a clinician, in part because no clear treatment outcome measures have been established. More information is needed to identify optimal ways to measure CT outcomes.

AIM

To identify ways to measure CT outcomes and to determine if there is a change in linguistic complexity and total talk time during conversation, samples were taken during CT and ST in two PWAs.

METHODS & PROCEDURES

Seventeen 6-min conversational samples per PWA were analyzed from a prior single-subject AB₁ AB₂ A alternating treatment study with randomized ordering of interventions across participants. Data were analyzed for seven measures of linguistic complexity using Systematic Analysis of Language Transcripts (SALT). Efficiency was measured using correct information units (CIUs) per minute and total talk time.

OUTCOMES & RESULTS

Per cent of complex utterances and propositional density were higher following CT. Four out of seven linguistic measures increased following ST. Total talk time was significantly greater for one PWA during CT compared with ST. No differences were found in CIUs/min across treatment types.

CONCLUSION & IMPLICATIONS

Linguistic complexity and efficiency appear to be conversational treatment outcome measures that are sensitive to change, which researchers might consider using.

On the diverse outcome of communication partner training of significant others of people with aphasia: an experimental study of six cases

BACKGROUND

Communication partner training (CPT) has been shown to improve the communicative environment of people with aphasia. Interaction-focused training is one type of training that provides an individualized intervention to participants. Although shown to be effective, outcomes have mostly been evaluated in non-experimental case studies.

AIMS

The aim of the controlled experimental intervention study was to evaluate an individualized approach in a CPT programme directed to significant others of people with aphasia. Specifically the effects on conversation partners' ability to support the person with aphasia in conversation and on the individuals with aphasias' perception of their functional communication were explored.

METHODS & PROCEDURES

Six dyads consisting of a person with aphasia and a significant other were included in a replicated single-subject design with multiple baselines across individuals. The intervention followed the interaction-focused communication training programme included in Supporting Partners of People with Aphasia in Relationships and Conversation (SPARRC). The main elements of the training consisted of supervised viewing of the couples' own video-recorded natural interaction and the formulation of individual goals for the adaptation of particular communicative strategies. Outcome was measured via blinded ratings of filmed conversational interaction obtained once a week throughout the different phases of baseline, intervention and follow-up. A rating scale to assess overall quality of conversation was used, taking into account both transfer of information and social aspects of conversation. Measures of perceived functional communication in the persons with aphasia were also collected from the individuals with aphasia and their conversation partners.

OUTCOMES & RESULTS

The results were mixed, with two of the six participants showing small improvements in ability to support their partner with aphasia in conversation. Half the participants with aphasia and half the significant others reported improvements on perceived functional communication in the person with aphasia after intervention, but no changes were statistically significant.

CONCLUSIONS & IMPLICATIONS

This study adds to the growing body of research concerning CPT by pinpointing the importance of careful consideration regarding set-up of training, suitability of participants and evaluation of outcome.

Conversation therapy for aphasia: a qualitative review of the literature

BACKGROUND

A diverse literature addresses elements of conversation therapy in aphasia including intervention rooted in conversation analysis, partner training, group therapy and behavioural intervention. Currently there is no resource for clinicians or researchers that defines and organizes this information into a coherent synopsis describing various conversation therapy practices.

AIMS

To organize information from varied sources into a descriptive overview of conversation therapy for aphasia.

METHODS & PROCEDURES

Academic search engines were employed to identify research articles published between 1950 and September 2013 reporting on conversation therapy for aphasia. Thirty articles met criteria for review and were identified as primary sources for the qualitative review. Using qualitative methodology, relevant data were extracted from articles and categories were identified to create a descriptive taxonomy of conversation therapy for aphasia.

MAIN CONTRIBUTION

Conversation interventions were divided into descriptive categories including: treatment participants (person with aphasia, partner, dyad), primary guiding orientation (conversation analysis, social model, behavioural, relationship centred), service delivery (individual, group), focus of intervention (generic/individualized; problem/solution oriented; compensatory), training methods (explicit/implicit; external/embedded), activities or tasks, and outcomes measured. Finally, articles were categorized by research design. There was marked variation in conversation therapy approaches and outcome measures reported and a notable gap in information about one-on-one conversation therapy for individuals with aphasia.

CONCLUSIONS & IMPLICATIONS

This review provides a description of various conversation therapy approaches and identified gaps in the existing literature. Valid measures of natural conversation, research on one-on-one conversation approaches for individuals with aphasia, and a systematic body of evidence consisting of high quality research are needed.

On the intersection of phonetic detail and the organization of interaction: clinical connections

The analysis of language use in real-world contexts poses particular methodological challenges. We codify responses to these challenges as a series of methodological imperatives. To demonstrate the relevance of these imperatives to clinical investigation, we present analyses of single episodes of interaction where one participant has a speech and/or language impairment: atypical prosody, echolalia and dysarthria. We demonstrate there is considerable heuristic and analytic value in taking this approach to analysing the organization of interaction involving individuals with a speech and/or language impairment.

Patterns of communicative interaction between a child with severe speech and physical impairments and her caregiver during a mealtime activity

BACKGROUND

Interaction between caregivers and children with severe impairments is closely related to the demands of daily activities. This study examines the relationship between interaction and the routine mealtime activity at home.

METHOD

Patterns of interaction between a child (aged 6 years and 6 months) with severe speech and physical impairments and her caregiver (focus dyad) and a child without impairments (aged 6 years and 6 months) and her caregiver (comparison dyad) were analysed using video recordings and activity-based communication analysis.

RESULTS

The focus dyad's interaction was unaided. The dyad did not use the Blissymbol board but communicated using words, vocalisations, word approximations, and body communication. Interaction in the focus dyad included relatively few pauses and frequent interchanges of short and sometimes simultaneous communicative contributions. Strong relations between patterns of interaction and immediate activity management goals such as assisting with eating, eating and drinking were found and compared for the two dyads. Results were discussed with regard to child development and communication intervention.

CONCLUSIONS

The focus dyad showed interactive efficiency and the fulfilment of goals relating to basic understanding and closeness, but mainly with regard to immediate mealtime issues. The comparison child and caregiver were more independent in the activity which made it possible for them to reach more extensive, and from a child perspective, age-adequate goals than the focus dyad.

A controlled study of changes in conversation following aphasia therapy for anomia

This paper investigates the relationship between change in picture naming with anomia therapy and changes in word retrieval in conversations between adults with aphasia and a regular conversational partner. We present data from two therapy projects (Hickin et al. [ 1 ] and Best et al. [ 2 ]). In each study, therapy involved cueing with the aim of improving retrieval of a set of nouns. Naming of the experimental items was assessed twice prior to therapy and again immediately afterwards. There was a significant change in word finding, as measured by picture naming, for the group and for 11 of the 13 participants. At the same time points, we collected conversations between the person with aphasia and a regular conversational partner. We analysed these using Profile of Word Errors and Retrieval in Speech (Herbert et al. [ 3 ]) and investigated a set of conversational variables predicted to change with therapy. Unsurprisingly, the conversation data is not straightforward. There is no significant change on the conversation measures for the group but some changes for individuals. We predicted change in word retrieval after therapy would relate to change in everyday conversations and tested this by correlating the change (post-therapy minus mean pre-therapy) in picture naming with the change in conversation variables. There was a significant positive relationship between the change in picture naming and change in some conversation measures including the number of nouns produced in 5 min of conversation (r = 0.50, p < 0.05, one-tailed) and the number of nouns produced per substantive turn (r = 0.55, p < 0.05, one-tailed). The findings suggest changes in word finding following therapy for aphasia can be reflected in changes in conversation. The clinical implications of the complex results are explored.

Conversation after right hemisphere brain damage: motivations for applying conversation analysis

Despite the well documented pragmatic deficits that can arise subsequent to Right Hemisphere Brain Damage (RHBD), few researchers have directly studied everyday conversations involving people with RHBD. In recent years, researchers have begun applying Conversation Analysis (CA) to the everyday talk of people with aphasia. This research programme has provided novel insights into the complex inter-relationship between impairment, language use, and interactional organization. This paper will argue that the detailed, inductive approach of CA is well suited to investigating pragmatic communication disorders resulting from RHBD, and will help to elaborate previous findings about RHBD and conversation. In particular, this paper will review and discuss previous investigations of conversation after RHBD, and put forward arguments relating to how CA might be applied to talk-in-interaction involving people with RHBD.

Beyond 'doctor and patient': developments in the study of healthcare interactions

Three decades of conversation analytic investigations of medical interaction have produced a rich collection of findings of sociological interest, from a diverse array of encounters. This paper briefly outlines the development of this field to provide a context for the special issue. The paper discusses how studies of doctor-patient interaction have revealed the ways in which participants organise the medical visit to accomplish tasks such as diagnosing and recommending treatment for illness, and how doctors and patients address various interactional issues and dilemmas that arise as they undertake these tasks. It then highlights a growing number of CA studies that explore medical settings and activities beyond the doctor-patient encounter. In doing so, it charts the distinctive interactional practices that emerge, for example, where participants are engaging in hands-on treatment, medical practitioners are interacting with one another, or various technologies are employed during the encounter. Finally, papers in this special issue are introduced and shown to build upon this latter tradition. The papers address distinctive practical problems and institutional dilemmas that arise in healthcare encounters and medical settings beyond dyadic doctor-patient interaction, with a focus on the participants' orientations to policy, their distinctive modes of participation, and the use of technology.

Co-constructed talk in the conversations of people with dysarthria and aphasia

This paper uses the methodology of conversation analysis (CA) to examine the practice of co-constructed turn and utterance production in impaired communication. An investigation of the conversations between two family dyads, featuring one person with dysarthric speech and one with aphasic language, reveals one way in which single turns and utterances are produced through the collaborative activities of two people in interaction. Such a practice is shown to operate without problems for the participants or the need for explicit acceptance by the speakers. It is proposed that co-construction in disordered speech and language is one way in which communicative competence is accomplished. By drawing attention to similarities in the consequences of dysarthria and aphasia in everyday interaction, it is suggested that researchers and clinicians might profitably look across disorder-specific boundaries.
