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

Development of ICF core set to profile communicative competence in dyadic communication among adults who use communication devices in Taiwan

PURPOSE

This study aimed to develop an ICF core set to profile communicative competence in dyadic communication among adults who use communication devices in Taiwan.

MATERIALS AND METHODS

The study was conducted following the release of a manual by the World Health Organisation (WHO) on how to develop the International Classification of Functioning, Disability and Health (ICF) core set in three phases: Preparatory Phase, Phase I, and Phase II. The Preparatory Phase helped collect and sort second-level ICF codes into a candidate list based on different perspectives, including the Systematic Literature Review Phase (i.e., researchers' perspectives), Empirical Multi-Center Study Phase (i.e., clinical perspectives), Qualitative Study Phase (i.e., perspectives of individuals with a health condition), and Expert Survey Phase (i.e., health professionals' perspectives). An ICF core set was developed from the candidate list in Phase I through the Delphi technique, and the content validity of this core set was assessed in Phase II.

RESULTS

Altogether, 94 s-level ICF codes in the candidate list from the Preparatory Phase were included in the three rounds of the Delphi technique for Phase I. Finally, these 94 s-level ICF codes were validated and included in the core set for Phase II, including 28 in Body Functions (b), 0 in Body Structures (s), 42 in Activities and Participation (d), and 24 in Environmental Factors (e).

CONCLUSIONS

The developed ICF core set provides an evaluation tool to profile communicative competence in dyadic communication among adults using communication devices. This core set identifies the gap and future opportunities for further examining the care providers' roles, together with exploring the environmental facilitators and barriers. The implications concerning rehabilitation, limitations, and the way forward are discussed.Implications to RehabilitationThis core set was first developed in the context of Taiwan from the perspectives of adults and professionals who used communication devices to profile communicative competence in dyadic communication.This core set, which can be utilised across health care disciplines, can serve as the foundation for more holistic evaluation, profiling levels of communicative competence in daily dyadic communication among adults who use communication devices.Rehabilitation providers may decide, based on this core set, if communication devices should be proposed for adults again in order to minimise the abandonment of subsidised communication devices.Levels of communicative competence in daily dyadic communication among adults who use communication devices can be profiled through this ICF core set.

The use of speech recognition technology by people living with amyotrophic lateral sclerosis: a scoping review

BACKGROUND

More than 80% of people living with Amyotrophic Lateral Sclerosis (plwALS) develop difficulties with their speech, affecting communication, self-identity and quality of life. Automatic speech recognition technology (ASR) is becoming a common way to interact with a broad range of devices, to find information and control the environment.ASR can be problematic for people with acquired neurogenic motor speech difficulties (dysarthria). Given that the field is rapidly developing, a scoping review is warranted.

AIMS

This study undertakes a scoping review on the use of ASR technology by plwALS and identifies research gaps in the existing literature.

MATERIALS AND METHODS

Electronic databases and relevant grey literature were searched from 1990 to 2020. Eleven research papers and articles were identified that included participants living with ALS using ASR technology. Relevant data were extracted from the included sources, and a narrative summary of the findings presented.Outcomes and Results: Eleven publications used recordings of plwALS to assess word recognition rate (WRR) word error rate (WER) or phoneme error rate (PER) and appropriacy of responses by ASR devices. All were found to be linked to severity of dysarthria and the ASR technology used. One article examined how speech modification may improve ASR accuracy. The final article completed thematic analysis of Amazon.com reviews for the Amazon Echo and plwALS were reported to use ASR devices to control the environment and summon assistance.

CONCLUSIONS

There are gaps in the evidence base: understanding expectations of plwALS and how they use ASR technology; how WER/PER/WRR relates to usability; how ASR use changes as ALS progresses.Implications for rehabilitationDevices that people can interact with using speech are becoming ubiquitous. As movement and mobility are likely to be affected by ALS and progress over time, speech interaction could be very helpful for accessing information and environmental control.However, many people living with ALS (plwALS) also have impaired speech (dysarthria) and experience trouble using voice interaction technology because it may not understand them.Although advances in automated speech recognition (ASR) technology promise better understanding of dysarthric speech, future research needs to investigate how plwALS use ASR, how accurate it needs to be to be functionally useful, and how useful it may be over time as the disease progresses.

Assessing and treating conversations with partners in Parkinson's disease: A scoping review of the evidence

Purpose: This is a scoping review of the methods used in published research to assess conversations and the interventions used to treat conversations between people with Parkinson's disease and their partners. Communication partners were defined as significant others or next-of-kin. The aims were to describe the assessment methods and interventions used, and to identify gaps in the literature.Method: Four online databases were used to identify peer reviewed journal articles in English, which assess and/or treat conversations in this population. The titles and abstracts of the obtained articles were screened and irrelevant articles were excluded. The full texts of the remaining articles were read to determine which studies met the inclusion/exclusion criteria of this review. The methods used, conversational aspects assessed, the treatments conducted and outcome measures used, and the speech and language domains targeted were charted in order to examine the extent of the evidence to inform future research directions.Result: Eight studies met inclusion criteria. "Conversation analysis" was the most widely used method to assess conversations. These studies assessed conversational aspects relating to the domains of pragmatics, fluency, prosody and semantics. They highlighted the role of communication partners to support conversational interactions by using repair strategies during a communication breakdown. Only one study treated conversations by implementing communication partner training.Conclusion: The findings of this review emphasise gaps in the literature. It highlights the need for future research implementing communication partner training. There is also a need to assess conversation skills of partners in order to determine which strategies would be most effective to support their interaction. It highlights the importance of incorporating a participation-based approach to assessment and intervention involving all communication partners. This may lead to enhanced support for people with Parkinson's disease and their families, thus improving their quality of life.

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.

Toward Empowering Conversational Agency in Aphasia: Understanding Mechanisms of Topic Initiation in People With and Without Aphasia

PURPOSE

This study examined topic initiation (TI) in conversations involving people with aphasia (PWA), matched people without aphasia (M-PWoA), and speech-language pathologists who were their conversation partners (SLP-Ps). For each speaker type, we analyzed patterns of distribution of typical mechanisms of TI and patterns of simultaneous use of multiple TI mechanisms. Lastly, we examined associations between use of simultaneous TI mechanisms and communicative success.

METHOD

Twenty PWA and 20 M-PWoA each participated in two conversations with SLP-Ps. Conversation samples were analyzed for TI locations and mechanisms, with results tallied for each speaker type following a published typology. A measure of communicative success was applied to TI utterances. Rank-order correlations were conducted to evaluate the patterns of distribution of the TI mechanisms between speaker types and the patterns of multiple mechanism usage between speaker types. Descriptive analysis was conducted to provide additional insight to the TI behaviors of each speaker type and to evaluate the relationship between multiple TI mechanisms and communicative success.

RESULTS

All speaker types used cohesion most often to achieve TI. PWA used an abrupt method of TI (noncoherent TI) more often than other speaker types. A single mechanism of TI was used most often by all speaker types, except for SLP-Ps when they were in conversations with PWA. In this case, SLP-Ps most often used two or more layered mechanisms of TI. SLP-Ps also used a highly salient TI mechanism with greater frequency when speaking with PWA than observed between other speaker types. When PWA layered mechanisms of TI, they appeared to be more likely to achieve better communicative success.

CONCLUSIONS

Specific, teachable behaviors such as favoring certain TI mechanisms and using multiple TI mechanisms may improve communicative success during TI for PWA. Furthermore, findings suggest that SLP-Ps modify their TI behaviors when speaking to PWA.

Correction and turn completion as collaborative repair strategies in conversations following Wernicke's aphasia

This study explores repair practices deployed by the interlocutor of a speaker with Wernicke's aphasia, their relationship to types of aphasic difficulty, and how mutual understanding and the progression of talk is maintained. A 75-year-old woman with Wernicke's aphasia of 16 months duration and her friend video recorded 36 minutes of conversation at home. Using conversation analytic methods two patterns of other-repair by the non-aphasic interlocutor were identified. The first practice was turn completion, which occurred in the context of self-initiated word search by the person with aphasia. The second was correction in the context of trouble with reference to person or place, manifested as an erroneous word, mis-selection of a gendered pronoun, or use of a pronoun where a person's name was expected. This correction was mainly overt, completed via a short side sequence dealing with the repair, although a few examples were embedded, where a word or phrase was replaced with a corrected form without overtly drawing attention to the correction. None of the examples included an account for the error. Unlike in typical talk, the person with aphasia did not repeat or use the corrected form in subsequent talk. For this dyad, correction and completion function as interactionally acceptable collaborative repair strategies, maintaining progressivity and a focus on topic development rather than on repair itself. There is no evidence that other-correction is dispreferred, which accords with recent findings for typical interaction but differs from other studies of aphasic talk. Correction should not be dismissed out of hand as a negative interactional practice when talking to someone with Wernicke's aphasia.

Dysarthria and other-initiated repair in everyday conversation

Dysarthria is commonly understood as a motor speech disorder characterized by symptoms that are framed as physiologically or acoustically measurable. The effects of dysarthria on social interaction through conversation have been reported but, in comparison with physical measures, remain relatively unexplored. Other-initiated repair sequences are particularly common in dysarthria-in-interaction, drawing attention to the actions of both participants in managing (un)intelligibility, rather than the behavior(s) of the person with dysarthric speech in isolation. These sequences merit detailed and ongoing investigation as they enable us to understand how dysarthria impacts on conversation and, critically, how participants attempt to manage difficulties when they arise. This study explores the organization of other-initiated repair sequences in a dyad where one participant has severe dysarthria arising from amyotrophic lateral sclerosis (ALS) also known as MND. Two hours of recordings were collected on four dates over a 12-month period with the data presented here from recording two. The evidence shows that the participants were able to resolve their troubles, but it required extensive work to both identify the trouble sources and to unravel the problems to reach a satisfactory understanding. The interactions presented in this paper reveal an important limitation of other initiation of repair. Physical restrictions were seen to play an important part in the dysarthric speaker's ability to position his talk in sequential context and successfully accomplish self-repair; particularly, third-turn repair. The present study has offered a depiction of layered conversational problems that other-initiation of repair may not completely resolve or, in some cases, multiply.

Direct assessment of emotional well-being from children with severe motor and communication impairment: a systematic review

PURPOSE

Explore methods used in peer-reviewed literature for obtaining self-expression of well-being information from children with severe motor and communication impairment (SMCI).

MATERIALS AND METHODS

A comprehensive search was conducted on 22 August 2019 through academic databases: CINAHL; Embase; MEDLINE; PsycINFO; InSpec; Compendex. Search strategies were informed by keywords under the following areas: (1) population: children with SMCI, (2) assessment methods: alternative to natural speech, paper and pencil report or standardized keyboard use (e.g., eye gaze) and (3) target information: well-being (e.g., quality of life). Studies were excluded if they focused on individuals over 25-years old, exclusively autism or typically developing children.

RESULTS

Non-duplicate studies of 10,986 were screened; 49 studies met inclusion criteria. Most studies used high-tech methods of self-expression in a single context (n = 17). Familiar partners play a significant role in self-expression; 18 studies required a familiar partner for children with SMCI to self-express. Thirty-five studies involved children self-expressing to solely adults, in comparison to 14 studies which involved peers.

CONCLUSION

Findings highlight the advancement of high-tech communication devices restricted to application in single contexts. Familiar partner knowledge of children with SMCI has the potential to be shared with others (e.g., respite care providers), enhancing both caregiver and child well-being. Future research that would enhance the literature could explore the assessment of emotional well-being for application in various contexts using multimodal methods. Opportunities for children with SMCI to express their emotional well-being can further influence the understanding and enhancement of participation, social connections, and experiences.IMPLICATIONS FOR REHABILITATIONUse of lower tech methods of self-expression to obtain information directly from children with severe motor and communication impairment (SMCI) remain more feasible in home and school contexts.By utilizing familiar partners' experiences and knowledge of the child, respite care providers, novel support workers, and others involved in the lives of children with SMCI can become further informed.Current high-tech methods for obtaining the emotional expressions of children with SMCI may benefit from incorporating multimodal approaches including lower tech methods, to be feasibly applied in real world contexts where well-being takes place.Further research on this topic is imperative to enable children with SMCI to self-express their emotional well-being which can enhance participation, activities, social connections, and experiences.

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.

Revisiting the Role of Augmentative and Alternative Communication in Aphasia Rehabilitation

Purpose The purpose of this article is to revisit the role of augmentative and alternative communication (AAC) in poststroke aphasia rehabilitation. The authors' intent is to provide a viewpoint that expands the use of AAC in poststroke aphasia rehabilitation. Specifically, we seek to clarify the role of AAC in restorative and participation approaches to aphasia rehabilitation while also considering the role of AAC in a comprehensive treatment plan. The authors support their viewpoint with citations from both the historic and contemporary literature on aphasia rehabilitation. Conclusions A thought-provoking viewpoint on the role of AAC in poststroke aphasia rehabilitation is proposed. More specifically, the versatility of AAC strategies is reviewed, with an emphasis on how AAC can be used to empower people with aphasia to fully participate and engage in life activities with increased independence. Moreover, we argue that AAC can be viewed as a dual-purpose tool that can simultaneously serve to drive intersystemic reorganization resulting in some improved language performance-and perhaps restoration of language function-while offering a communication alternative during inevitable anomic events.

"By the Way"… How People With Aphasia and Their Communication Partners Initiate New Topics of Conversation

Purpose The ability to initiate new topics of conversation is a basic skill integral to communicative independence and agency that is susceptible to breakdown in aphasia (Barnes, Candlin, & Ferguson, 2013), yet this discourse skill has received little research attention. Healthy adults (HAs) follow 3 established patterns of structural organization to cue the conversation partner when an utterance is intended to initiate a new topic (Schegloff & Sacks, 1973; Svennevig, 1999). In addition, speakers have the option to use these mechanisms of topic initiation (TI) individually or in conjunction with one another. Occasionally, speakers do not follow these conversational macrostructure expectations, in which case TI occurs abruptly, referred to as a noncoherent TI (NC-TI; Mentis & Prutting, 1991). Understanding how TI is disrupted by aphasia requires foundational knowledge regarding the relative use/combined use of TI mechanisms and NC-TI in HAs and persons with aphasia (PWAs). The purpose of this study is to investigate how PWAs and their conversation partners initiate new topics of conversation and to determine the relationship between the number of TI methods used and communicative success (CS) in persons with mild aphasia (PWA-Mild) and persons with moderate and severe aphasia (PWA-Mod/Sev). Method Six PWA-Mild and 4 PWA-Mod/Sev engaged in 15-min unstructured conversations with different HA partners. Utterances were coded for types of TI used by both partners and were evaluated for CS using a 4-point scale (Leaman & Edmonds, 2019) for PWAs. Results/Implications PWAs used NC-TI with a much greater frequency than HAs who never used NC-TI. The rate of NC-TI was associated with increased severity of aphasia. HAs and PWA-Mild used cohesion most often as the method for TI, while PWA-Mod/Sev used it least often. CS was moderately positively correlated with the number of methods of TI used in PWA-Mod/Sev. However, no such correlation existed for PWA-Mild; this group achieved a high degree of CS on TI utterances, independent of the number of methods of TI used. Findings include the clinical implication suggesting PWA-Mod/Sev may benefit from simultaneous use of TI mechanisms to achieve better CS during conversation.

Conversation in Aphasia Across Communication Partners: Exploring Stability of Microlinguistic Measures and Communicative Success

Purpose The aim of this study was to determine if people with aphasia demonstrate differences in microlinguistic skills and communicative success in unstructured, nontherapeutic conversations with a home communication partner (Home-P) as compared to a speech-language pathologist communication partner (SLP-P). Method Eight persons with aphasia participated in 2 unstructured, nontherapeutic 15-minute conversations, 1 each with an unfamiliar SLP-P and a Home-P. Utterance-level analysis evaluated communicative success. Two narrow measures of lexical relevance and sentence frame were used to evaluate independent clauses. Two broad lexical and morphosyntactic measures were used to evaluate elliptical and dependent clauses and to evaluate independent clauses for errors beyond lexical relevance and sentence frame (such as phonological and morphosyntactic errors). Utterances were further evaluated for presence of behaviors indicating lexical retrieval difficulty (pauses, repetitions, and false starts) and for referential cohesion. Results No statistical differences occurred for communicative success or for any of the microlinguistic measures between the SLP-P and Home-P conversation conditions. Four measures (2 of lexical retrieval and 1 each of communicative success and grammaticality) showed high correlations across the 2 conversation samples. Individuals showed variation of no more than 10 percentage points between the 2 conversation conditions for 46 of 56 data points. Variation greater than 10 percentage points tended to occur for the measure of referential cohesion and primarily for 1 participant. Conclusions Preliminary findings suggest that these microlinguistic measures and communicative success have potential for reliable comparison across Home-P and SLP-P conversations, with the possible exception of referential cohesion. However, further research is needed with a larger, more diverse sample. These findings suggest future assessment and treatment implications for clinical and research needs.

Telling tales: unlocking the potential of AAC technologies

Augmentative and alternative communication (AAC) has been transformed by the social media revolution made possible by the emergence of mobile technology. The cumbersome dedicated devices of the 1970s have evolved into a burgeoning AAC app industry. However, the limited use and abandonment of AAC technologies remains high. Unlocking the untapped potential of technology requires a paradigm shift in the design of AAC technologies by building systems that minimize the cognitive load placed on users, adapting to their individual physical and language needs. Telling Tales shares insights and stories of how the combination of user-centred design, interdisciplinary research and the application of intelligent computing is providing a vision of future generations of AAC technologies.

Impaired Verbal Communication: diagnosis review in patients with Amyotrophic Lateral Sclerosis

ABSTRACT Objective: To review the contents of the nursing diagnosis of Impaired Verbal Communication in patients with Amyotrophic Lateral Sclerosis. Method: For the review of this diagnosis we used the integrative review. The 21 selected articles were submitted to a careful concept analysis for the definition of the diagnostic concept and review of its elements. Results: It is recommended, in addition to a new definition for the diagnosis of Impaired Verbal Communication, the incorporation of twelve Risk Factors, the maintenance of three others and the relocation of a Defining Characteristic for Risk Factor. It is also recommended the incorporation of nine Defining Characteristics and the modification of the nomenclature of the other three that already make up the NANDA-I. Conclusion: The content review process subsidized a clarification of the chosen concept, contributing to a future refinement and improvement of the study diagnosis and its components present in NANDA-I.

Revisiting Communicative Competence in Augmentative and Alternative Communication

OBJECTIVE

This tutorial paper is to explore the novel nature of communicative competence in augmentative and alternative communication (AAC) practice by comparing it to communicative competence in naturally verbal dyadic communication.

PATIENTS AND METHODS

This paper first reviews the four domains of communicative competence in AAC practice. Second, it examines competence in dyadic communications between naturally verbal people without disabilities, deriving new insights and using these to analyze the evolution of communicative competence in AAC practice.

RESULTS

Communicative competence in AAC practice should be reconceptualized from a new perspective as dyadic, learned, co-constructed, and of relative value, ascertained through performance.

CONCLUSION

In the past decades, the study of communicative competence in AAC practice has primarily focused on individual persons who use AAC. However, the conceptualization of communicative competence should shift away from an individualized construct toward a dyadic construct. This leads to a discussion of potential implications and future research directions. This paper might offer AAC researchers and practitioners an opportunity to deepen their understanding of communicative competence and promote more positive outcomes for people who use AAC.

Recipient participation in conversations involving participants with fluent or non-fluent aphasia

The present study compares the ways in which conversational partners manage expressive linguistic problems produced by participants with fluent vs. non-fluent aphasia. Both everyday conversations with family members and institutional conversations with speech-language therapists were examined. The data consisted of 110 conversational sequences in which the conversational partners addressed expressive aphasic problems. Most problems of the speaker with fluent aphasia were locally restricted phonological and word-finding errors, which were immediately repaired. In contrast, the sparse expression of the speaker with non-fluent aphasia was co-constructed by conversational partners in long negotiation sequences to establish shared understanding. Some differences between recipient participation in everyday and institutional conversation were found. The results emphasise the relevance of the nature of the expressive linguistic problems on participation in interaction. They also add to the clinical knowledge of handling aphasic problems in conversation. This knowledge can be used for developing interaction-focused intervention.

Multiple repair sequences in everyday conversations involving people with Parkinson's disease

BACKGROUND

Features of dysarthria associated with Parkinson's disease (PD), such as low volume, variable rate of speech and increased pauses, impact speaker intelligibility. Those affected report restricted interactional participation, although this area is under explored.

AIMS

To examine naturally occurring instances of problems with intelligibility that resulted in multiple attempts at repair in order to consider repair initiation strategies that might restrict or enhance participation.

METHODS & PROCEDURES

Thirteen people with PD (PwPD) video-recorded over 10 h of informal conversation data in their home setting involving familiar conversation partners (CPs). Using a conversation analytic (CA) approach, and drawing on an existing typology of repair initiators (RIs) for everyday talk-in-interaction and their relative power to locate a turn's repairable element, the design and ordering of RIs used by CPs was addressed, alongside their local consequences.

OUTCOMES & RESULTS

CPs tended to increase the specificity of their RIs in line with the existing typology, progressing from open class forms (e.g. 'mm?') to more specific forms (e.g. questions/partial repeats). Repeated open class repair initiators (OCRIs) were used where PD speakers' self-repair attempts provided limited information. Sometimes, however, specificity was increased too soon, before enough syntactic knowledge was gleaned, which resulted in an extended repair sequence. Where one OCRI followed another, the second always took a different form: lexically or in terms of prosodic/non-verbal features. RI forms not described in the existing typology were also identified, such as 'prompts to modify speech' (e.g. 'Speak louder') and repeating/rephrasing the original first pair part (e.g. question), and their effectiveness examined.

CONCLUSIONS & IMPLICATIONS

First steps are presented towards the design of a communication intervention promoting the efficient resolution of repair to moderate social withdrawal and increase participation for this client group. Future research will need to explore the feasibility and acceptability of such a resource.

Semantic trouble sources and their repair in conversations affected by Parkinson's disease

BACKGROUND

It is known that dysarthria arising from Parkinson's disease may affect intelligibility in conversational interaction. Research has also shown that Parkinson's disease may affect cognition and cause word-retrieval difficulties and pragmatic problems in the use of language. However, it is not known whether or how these problems become manifest in everyday conversations or how conversation partners handle such problems.

AIMS

To describe the pragmatic problems related to the use of words that occur in everyday conversational interaction in dyads including an individual with Parkinson's disease, and to explore how interactants in conversation handle the problems to re-establish mutual understanding.

METHODS & PROCEDURES

Twelve video-recorded everyday conversations involving three couples where one of the individuals had Parkinson's disease were included in the study. All instances of other-initiated repair following a contribution from the people with Parkinson's disease were analysed. Those instances involving a trouble source relating to the use of words were analysed with a qualitative interaction analysis based on the principles of conversation analysis.

OUTCOMES & RESULTS

In 70% of the instances of other-initiated repair the trouble source could be related to the semantic content produced by the individual with Parkinson's disease. The problematic contributions were typically characterized by more or less explicit symptoms of word search or use of atypical wording. The conversation partners completed the repair work collaboratively, but typically the non-impaired individual made a rephrasing or provided a suggestion for what the intended meaning had been.

CONCLUSIONS & IMPLICATIONS

In clinical work with people with Parkinson's disease and their conversation partners it is important to establish what type of trouble sources occur in conversations in a specific dyad. It may often be necessary to look beyond intelligibility and into aspects of pragmatics to understand more fully the impact of Parkinson's disease on everyday conversational interaction.

Communicative strategies used by spouses of individuals with communication disorders related to stroke-induced aphasia and Parkinson's disease

BACKGROUND

A communicative disability interferes with the affected person's ability to take active part in social interaction, but non-disabled communication partners may use different strategies to support communication. However, it is not known whether similar strategies can be used to compensate for different types of communicative disabilities, nor what factors contribute to the development of a particular approach by communication partners.

AIMS

To develop a set of categories to describe the strategies used by communication partners of adults who have problems expressing themselves due to neurogenic communicative disabilities. The reliability of assessment was a particular focus.

METHODS & PROCEDURES

The material explored consisted of 21 video-recorded everyday conversations involving seven couples where one spouse had a communicative disability. Three of the dyads included a person with dysarthria and anomia related to later stages of Parkinson's disease, while four of them included a person with stroke-induced aphasia involving anomia. First a qualitative interaction analysis was performed to explore the strategies used by the communication partners when their spouses had problems expressing themselves. The strategies were then categorized, the reliability of the categorizations was explored and the relative frequency of the various strategies was examined.

OUTCOMES & RESULTS

The analysis of the conversational interactions resulted in a set of nine different strategies used by the communication partners without a communicative disability. Each of these categories belonged to one of three overall themes: No participation in repair; Request for clarification or modification; and Providing candidate solutions. The reliability of the categorization was satisfactory. There were no statistically significant differences between diagnoses in the frequency of use of strategies, but the spouses of the persons with Parkinson's disease tended to use open-class initiations of repair more often than the spouses of the persons with aphasia.

CONCLUSIONS & IMPLICATIONS

The types of strategies used by spouses of persons with neurogenic communicative disabilities seem to be more strongly associated with individual characteristics of communicative ability than with the type of disorder involved. The set of categories developed in this study needs to be trialled on larger groups of participants, and modified if and as necessary, before it can be regarded as a valid system for the description of such strategies in general. Once this has been done it may become a useful instrument in the assessment of the strategies used by communication partners of individuals with communicative disabilities.

Communication support through multimodal supplementation: a scoping review

Speech supplementation strategies improve spoken communication for people with motor speech disorders who experience reduced speech intelligibility. The purpose of this review was to summarize the literature on traditional supplementation strategies (e.g., alphabet supplementation, topic supplementation, and gestural supplementation) and to expand the definition of speech supplementation to include additional modalities, such as augmenting speech with pictures via mobile technology, and conversation management strategies. Results showed that studies of traditional supplementation consistently reported positive outcomes, including increased intelligibility, decreased speech rate, and positive attitudes toward speakers. New modalities, such as supplementing speech through digital photos, may come to be integrated with traditional approaches, given the proliferation of digital photography and mobile tablet technologies. In addition, new research is exploring the role of communication partners in dyads where one speaker has dysarthria, as well as strategies that communication partners employ to understand dysarthric speech.

Confirming and denying in co-construction processes: a case study of an adult with cerebral palsy and two familiar partners

For individuals with complex communication needs, one of the most frequent communicative strategies is the co-construction of meaning with familiar partners. This preliminary single-case study gives insight into a special sequential pattern of co-construction processes - the search sequence - particularly in relation to the processes of confirming and denying meanings proposed by familiar interaction partners. Five different conversations between an adult with cerebral palsy and complex communication needs and two familiar co-participants were videotaped and analyzed using the methodology of conversation analysis (CA). The study revealed that confirmations and denials are not simply two alternative actions, but that several possibilities to realize confirmations and denials exist that differ in their frequency and that have different consequences for the sequential context. This study of confirmations and denials demonstrates that co-construction processes are more complex than have previously been documented.

A primer for doing talk-in-interaction research in Augmentative and Alternative Communication

The study of talk-in-interaction is focused on how people conduct social interactions in real world situations, in real-time. The purpose of this article is to provide a primer for understanding talk-in-interaction research, conversation analysis and microanalysis in the AAC field. An overview of talk-in-interaction research and a discussion of important issues in the field will be presented, followed by a tutorial on conducting microanalytic investigations in AAC.

The effect of familiarity of conversation partners on conversation turns contributed by augmented and typical speakers

The purpose of this current research was to determine the effect of familiarity of conversation partners on contributed conversation turns to dyadic conversation between individuals who use AAC and typically speaking conversation partners. Three groups (G1-G3) participated in this study. Each group contained seven participants, including an individual who used a speech-generating device (SGD) and familiar and unfamiliar conversation partners. Each 20-min dyadic conversation was video-recorded for analysis of contributed conversation turns. The findings of the current study showed that the asymmetries of contributed conversation turns exist in both familiar and unfamiliar dyadic conversation between AAC users and typically speaking conversation partners. In addition, the asymmetry in the familiar dyadic conversation did not differ from that in the unfamiliar dyadic conversation.

Adaptation to aphasia: grammar, prosody and interaction

This paper investigates recurrent use of the phrase very good by a speaker with non-fluent agrammatic aphasia. Informal observation of the speaker's interaction reveals that she appears to be an effective conversational partner despite very severe word retrieval difficulties that result in extensive reliance on variants of the phrase very good. The question that this paper addresses using an essentially conversation analytic framework is: What is the speaker achieving through these variants of very good and what are the linguistic and interactional resources that she draws on to achieve these communicative effects? Tokens of very good in the corpus were first analyzed in a bottom-up fashion, attending to sequential position, structure and participant orientation. This revealed distinct uses that were subsequently subjected to detailed acoustic analysis in order to investigate specific prosodic characteristics within and across the interactional variants. We identified specific clusters of prosodic cues that were exploited by the speaker to differentiate interactional uses of very good. The analysis thus shows how, in the adaptation to aphasia, the speaker exploits the rich interface between prosody, grammar and interaction both to manage the interactional demands of conversation and to communicate propositional content.

A qualitative study of interference with communicative participation across communication disorders in adults

PURPOSE

To explore the similarities and differences in self-reported restrictions in communicative participation across different communication disorders in community-dwelling adults.

METHOD

Interviews were conducted with 44 adults representing 7 different medical conditions: spasmodic dysphonia, multiple sclerosis, stroke, stuttering, Parkinson's disease, amyotrophic lateral sclerosis, and laryngectomy. This article represents a secondary analysis of qualitative data collected in cognitive interviews during development of the Communicative Participation Item Bank. The data were analyzed to identify themes in participants' experiences related to communicative participation.

RESULTS

Participants described many situations in which they experienced interference in communicative participation. Two themes emerged from the data. The first theme was Interference is both "functional" and "emotional," in which participants defined interference as limitations in accomplishing tasks and emotional consequences. The second theme was "It depends"-sources of interference, in which participants described many variables that contribute to interference in participation. Participants had limited control of some variables such as symptoms and environmental contexts, but personal decisions and priorities also influenced participation.

CONCLUSIONS

Despite different impairments and activity limitations, participants described similar communicative participation restrictions. These similarities may have theoretical and clinical implications in terms of how we assess, treat, and study the participation restrictions associated with communication disorders.

Investigating interactional competencies in Parkinson's disease: the potential benefits of a conversation analytic approach

BACKGROUND

Around 70% of people who develop Parkinson's disease (PD) experience speech and voice changes. Clinicians often find that when asked about their primary communication concerns, PD clients will talk about the difficulties they have 'getting into' conversations. This is an important area for clients and it has implications for quality of life and clinical management.

AIMS

To review the extant literature on PD and communication impairments in order to reveal key topic areas, the range of methodologies applied, and any gaps in knowledge relating to PD and social interaction and how these might be usefully addressed.

METHODS & PROCEDURES

A systematic search of a number of key databases and available grey literatures regarding PD and communication impairment was conducted (including motor speech changes, intelligibility, cognitive/language changes) to obtain a sense of key areas and methodologies applied. Research applying conversation analysis in the field of communication disability was also reviewed to illustrate the value of this methodology in uncovering common interactional difficulties, and in revealing the use of strategic collaborative competencies in naturally occurring conversation. In addition, available speech and language therapy assessment and intervention approaches to PD were examined with a view to their effectiveness in promoting individualized intervention planning and advice-giving for everyday interaction.

MAIN CONTRIBUTION

A great deal has been written about the deficits underpinning communication changes in PD and the impact of communication disability on the self and others as measured in a clinical setting. Less is known about what happens for this client group in everyday conversations outside of the clinic. Current speech and language therapy assessments and interventions focus on the individual and are largely impairment based or focused on compensatory speaker-oriented techniques. A conversation analysis approach would complement basic research on what actually happens in everyday conversation for people with PD and their co-participants.

CONCLUSIONS & IMPLICATIONS

The potential benefits of a conversation analysis approach to communication disability in PD include enabling a shift in clinical focus from individual impairment onto strategic collaborative competencies. This would have implications for client-centred intervention planning and the development of new and complementary clinical resources addressing participation. The impact would be new and improved support for those living with the condition as well as their families and carers.

Acquired dysarthria in conversation: methods of resolving understandability problems

BACKGROUND

People with acquired progressive dysarthria typically experience increased problems with intelligibility in everyday conversation as their disease progresses. Such problems are likely to impact on both the person with dysarthria and those with whom they interact. If this is the case then we may ask questions not just about the nature of these problems but how it is that such problems are dealt with by participants when they occur.

AIMS

To investigate ways through which problems resulting from dysarthria in everyday conversation are resolved by participants. Further, to examine some of the features of repair resolution, particularly where understanding of self-repair attempts themselves prove difficult.

METHODS & PROCEDURES

Video data of natural conversation from two dyads were selected for this paper. One dyad features a 58 year-old man with multiple sclerosis and moderate intelligibility problems, the other a 79 year-old woman with motor neurone disease with mild to moderate intelligibility problems. Both elected to be recorded in conversation with their spouses. The dyads were video-recorded at home with no researcher present. Using the methods of Conversation Analysis (CA) a collection of sequences was identified and transcribed. The sequences were analysed with reference to how the participants resolve problems in the understanding of dysarthric speech.

OUTCOMES & RESULTS

It is shown how some problems resulting from dysarthria in conversation can be resolved relatively quickly, particularly where a specific element of a prior turn is highlighted by the recipient as problematic. In other instances, the recipient's understanding problem may be more global. These result in longer repair sequences in which problematic elements are addressed individually. Such a resolution method is ultimately successful but may also be characterised by additional understanding problems. These findings draw attention to an important distinction between intelligibility and understandability.

CONCLUSIONS & IMPLICATIONS

It is concluded that problems resulting from dysarthria in conversation can require extensive repair work involving both parties. This has implications for the assessment of dysarthria in everyday conversation and also the promotion of intervention strategies that encompass the activities of both participants when dealing with dysarthria in interaction. These findings may be usefully employed in informing both direct clinical work and through training those who work with this client group and their significant others.
