Collaboration, trouble and repair in multiparty interactions involving couples with dementia or aphasia

Co-constructed communication therapy for individuals with acquired brain injury: A systematic review

BACKGROUND

Meaningful, varied, joyful conversation is an important therapy target for adults with language or cognitive-communication disorders following acquired brain injury (ABI). However, the complexity of daily communication is often reduced to component parts within intervention programmes, with mixed evidence of generalization to everyday conversation. Interventions targeting co-construction of communication within a dyad offer a structured way in which to retain and treat elements of everyday conversation for individuals and their communication partner (CP). Such interventions exist but they are variably labelled, target different ABI populations and have not been synthesized.

AIMS

To identify the nature, scope and effects of intervention studies targeting co-constructed communication in adults with ABI.

METHOD

This systematic review was completed using PRISMA Guidelines. Six databases (MEDLINE, Embase, CINAHL, Scopus, LLBA, PsychInfo) were searched and 1210 studies were screened. Data were extracted and studies were rated for methodological quality and completeness of reporting. Outcome measures and effects of treatment were collated through descriptive synthesis.

MAIN CONTRIBUTION

This review highlights an emerging evidence base in relation to an intervention approach that targets everyday communication. Co-constructed communication interventions have been reported by 13 studies, from a total of 206 participants with post-stroke aphasia, traumatic brain injury and progressive language impairments. These interventions take a range of formats, including referential communication tasks, retell/recount therapies and communication training programmes. Methodological quality evaluation indicated mostly low-level study designs. Heterogeneity was identified in primary outcome measures, with 28 unique primary outcome measures reported across studies. Most studies demonstrated change in task-specific or broad communication outcome measures.

CONCLUSIONS

Co-constructed communication interventions may offer clinicians a systematic, protocolized, replicable way to target everyday communication for adults with ABI. More high-quality, experimental designs with complete reporting and psychometrically sound outcome measures are needed to strengthen the evidence base.

WHAT THIS PAPER ADDS

What is already known on this subject Everyday conversation is an important therapy target for adults with ABI, but there is mixed evidence of therapy gains generalizing to everyday life. Many interventions reduce conversation to component parts such as naming or sentence construction. A different approach is needed to capture the social, dyadic, interactive and multifaceted nature of conversation. We propose the term 'co-constructed communication interventions' as a therapy genre targeting semi-structured dialogue. These interventions retain elements of everyday conversation (such as multimodal communication and situating tasks within dyads), combined with experimental elements (where stimuli prompt interactions and responses can be scored against normative data). What this paper adds to existing knowledge This review proposes and describes a distinct genre of discourse intervention within the current evidence base with a novel operational definition of 'co-constructed communication'. What are the potential or actual clinical implications of this work? Co-constructed communication interventions directly target elements of everyday communication by situating the therapy goals within a dyadic, interactive, multimodal task. A range of intervention tasks have been identified, including collaborative storytelling and problem-solving. This review will be of interest to clinicians working with adults with ABI; co-constructed communication interventions may offer a useful, replicable way to target aspects of everyday communication. This synthesis of the current evidence base encourages clinicians' informed, evidence-based decisions around these interventions.

A longitudinal observational study of home-based conversations for detecting early dementia: protocol for the CUBOId TV task

INTRODUCTION

Limitations in effective dementia therapies mean that early diagnosis and monitoring are critical for disease management, but current clinical tools are impractical and/or unreliable, and disregard short-term symptom variability. Behavioural biomarkers of cognitive decline, such as speech, sleep and activity patterns, can manifest prodromal pathological changes. They can be continuously measured at home with smart sensing technologies, and permit leveraging of interpersonal interactions for optimising diagnostic and prognostic performance. Here we describe the ContinUous behavioural Biomarkers Of cognitive Impairment (CUBOId) study, which explores the feasibility of multimodal data fusion for in-home monitoring of mild cognitive impairment (MCI) and early Alzheimer's disease (AD). The report focuses on a subset of CUBOId participants who perform a novel speech task, the 'TV task', designed to track changes in ecologically valid conversations with disease progression.

METHODS AND ANALYSIS

CUBOId is a longitudinal observational study. Participants have diagnoses of MCI or AD, and controls are their live-in partners with no such diagnosis. Multimodal activity data were passively acquired from wearables and in-home fixed sensors over timespans of 8-25 months. At two time points participants completed the TV task over 5 days by recording audio of their conversations as they watched a favourite TV programme, with further testing to be completed after removal of the sensor installations. Behavioural testing is supported by neuropsychological assessment for deriving ground truths on cognitive status. Deep learning will be used to generate fused multimodal activity-speech embeddings for optimisation of diagnostic and predictive performance from speech alone.

ETHICS AND DISSEMINATION

CUBOId was approved by an NHS Research Ethics Committee (Wales REC; ref: 18/WA/0158) and is sponsored by University of Bristol. It is supported by the National Institute for Health Research Clinical Research Network West of England. Results will be reported at conferences and in peer-reviewed scientific journals.

Conversational repair in individuals with Alzheimer disease

PURPOSE

many of the difficulties that usually arise in colloquial conversation may be repaired as the interaction develops. Conversational repair is a linguistic strategy that indicates evidence of the partners' abilities to promote necessary mutual understanding for effective communication. This study aims to analyze the oral text repairs of 10 older adults with Alzheimer's dementia (AD) and 10 older adults without dementia, as well as to verify whether they are a useful element for language disorders identification in AD.

METHODS

autobiographical interview and application of items of the MetAphAs protocol were proposed. Data were analyzed based on the methodology of conversational analysis.

RESULTS

the results indicated that self-initiated repairs are frequent in both groups, although subjects with AD made more use of inadequate repairs, which did not favor mutual understanding. Hetero-repairs occurred most frequently in conversations with individuals with AD, suggesting the need for interlocutor's intervention to adjust a specific utterance.

CONCLUSION

this research has shown that using repair strategies is sensitive to individuals with AD cognitive performance.

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.

Impact of aphasia on communication in couples

BACKGROUND

Communication is at the heart of relationships, especially for couples. When language is altered, as it is in aphasia, communication in couples can be affected.

AIMS

To explore how members of a couple perceive the impact of aphasia on their communication.

METHODS & PROCEDURES

Nine French-speaking couples participated in the study. One member of each couple had chronic stroke-related aphasia, which varied in type and severity. The 18 participants took part in individual semi-structured interviews to understand their perspective on communication within their couple. The interviews were recorded, transcribed and analysed with a qualitative thematic analysis.

OUTCOMES & RESULTS

Three main themes emerged: (1) experiencing limitations in conversation; (2) assuming changed speaking and listening roles; and (3) experiencing new emotions, feelings and reactions in communication. Couples experienced diminished frequency and duration of conversations as well as restrained topics after the onset of aphasia. Ten participants reported that each member's communication role of listener versus speaker had changed, and that the person with aphasia became a less active participant. Communication was described as 'positive' before aphasia and 'fine' to 'difficult' following aphasia. Persons with aphasia and spouses expressed experiencing difficulties managing emotions related to communication. Frustration and caution towards the other member of the couple had been associated with aphasia. In addition, five spouses reported that they refrained from initiating discussions on specific topics in order to maintain a positive relationship with the person with aphasia.

CONCLUSION & IMPLICATIONS

The results describe some of the consequences of aphasia on communication in couples. Clinicians could use interviews to understand the impact of aphasia on a couple's communication. This may help to design communication partner training (CPT) that better aligns with the particular needs of couples living with aphasia, acknowledging the importance of emotional dimensions of relationships. What this paper adds What is already known on the subject The general psychosocial impacts of aphasia on persons with aphasia and spouses are known. Their conversations have been described and used as a focus for CPT. However, CPT may be difficult to implement in clinical settings. What this paper adds to the existing knowledge This paper provides in-depth descriptions of perceived changes in relational or transactional communication by the PWA and their spouse. The frequency, duration and topics of conversations changed and emotions such as frustration and caution appeared. Participants assumed changed speaking and listening roles. What are the potential or actual clinical implications of this work? The participants' description of communication could be used by speech-language pathologists when conducting CPT to illustrate how aphasia affects communication in couples. Emotions emerging as a result of changes in communication following aphasia should be assessed before CPT and could be a starting point to work on communication. This could support clients' commitment in CPT.

Common and distinct components of communication partner training programmes in stroke, traumatic brain injury and dementia

BACKGROUND

Communication partner training (CPT) programmes for health and care staff working with people with the neurologically based communication disorders associated with stroke, traumatic brain injury (TBI) and dementia are efficacious in improving communication. However, current programmes are lengthy and disorder specific, and therefore may not be suitable as staff training tools in environments with people with multiple communication disorders, and services with a variety of neurological populations.

AIMS

To identify common and distinct components of CPT programmes for stroke, TBI and dementia in order to determine whether there are common delivery methods and content that can be consolidated to improve implementation of CPT in health and care services.

METHODS & PROCEDURES

A qualitative enquiry was used. Four CPT programmes targeting three disorders were identified from systematic reviews and literature searches. Programme data were recorded onto data sheets from manuals, study articles and supplementary materials, and were categorized using the Intervention Taxonomy (ITAX). Content analysis and elements of constant comparative analysis were employed to analyse the CPT programmes.

OUTCOMES & RESULTS

Delivery characteristics were similar across all four programmes. All were delivered face to face in either group or individual contexts. However, duration varied from 1 to 35 h. Six of the 12 categories of information provided were common across all programmes, including 'strategy' 'background to disorder', 'information about communication', 'information about program', 'negative behaviours to avoid' and 'purpose of program'. Programmes differed in the types of skill-building techniques used, with the most common being videos (3/4 programmes), discussions (2/4 programmes) and trainer demonstrations (2/4 programmes). While strategies provided to trained partners targeted similar domains of communication, only 3/96 individual strategies were common to all programmes.

CONCLUSIONS & IMPLICATIONS

There are both common and distinct components in content and delivery methods across CPT programmes. Further research is needed to evaluate the distinct components of the programmes, to determine which individual strategies are efficacious, and which approach to skill-building techniques is most effective. The present study has contributed a comprehensive list of programme components, which can form a basis for describing and refining CPT programmes in future.

Toward the Development of SMART Communication Technology: Automating the Analysis of Communicative Trouble and Repair in Dementia

BACKGROUND AND OBJECTIVES

Communication difficulties have been reported as one of the most stress-inducing aspects of caring for people with dementia. Notably, with disease progression comes an increase in the frequency of communication difficulty and a reduction in the effectiveness of attempts to remedy breakdowns in communication. The aim of the current research was to evaluate the utility of an automated discourse analysis tool (i.e., Discursis) in distinguishing between different types of trouble and repair signaling behaviors, demonstrated within conversations between people with dementia and their professional care staff.

RESEARCH DESIGN AND METHODS

Twenty conversations between people with dementia and their professional care staff were human-coded for instances of interactive/noninteractive trouble and typical/facilitative repair behaviors. Associations were then examined between these behaviors and recurrence metrics generated by Discursis.

RESULTS

Significant associations were identified between Discursis metrics, trouble-indicating, and repair behaviors.

DISCUSSION AND IMPLICATIONS

These results suggest that discourse analysis software is capable of discriminating between different types of trouble and repair signaling behavior, on the basis of term recurrence calculated across speaker turns. The subsequent recurrence metrics generated by Discursis offer a means of automating the analysis of episodes of conversational trouble and repair. This achievement represents the first step toward the future development of an intelligent assistant that can analyze conversations in real time and offers support to people with dementia and their carers during periods of communicative trouble.
