"They are dealing with people's lives ": Diagnostic and post-diagnostic healthcare experiences in primary progressive aphasia.

PURPOSE: The healthcare experience is a multifaceted and varied process, particularly for people living with complex conditions such as primary progressive aphasia (PPA). Different experiences influence pathways through the health system, impacting client outcomes. To our knowledge, no previous studies have directly explored the healthcare experiences of people with PPA and their families. This study aimed to explore the experiences of people living with PPA from the perspective of both the person with PPA and their families during diagnostic and post-diagnostic phases, and to identify factors influencing service access and perceptions of quality of care. METHOD: The study followed an Interpretive Phenomenological Analysis (IPA) approach. In-depth, semi-structured interviews were completed with three people with PPA and their primary care partner, and two further care partners of people with PPA. RESULT: Five superordinate themes were identified: characterising the assessment experience, getting a diagnosis, moving beyond the diagnosis, participant interactions with clinicians, and overall service provision. The five superordinate themes comprised 14 subthemes. CONCLUSION: The study provides preliminary insights into the complexity of the PPA healthcare journey, and the need for increased accessibility of information and supports following diagnosis. The findings inform recommendations for improving quality of care and the development of a PPA service framework or care pathway.

"Please Don't Assess Him to Destruction": The R.A.I.S.E. Assessment Framework for Primary Progressive Aphasia.

PURPOSE: Speech-language pathologists (SLPs) assess people with primary progressive aphasia (PPA) through measurements of speech, language, communication, and well-being, with the aims of identifying challenges and strengths, monitoring change, and informing treatment directions and supports. The purpose of this clinical focus article is to highlight the necessity for person-centered assessment specific to PPA and to conceptualize a framework that acknowledges the multifaceted nature of assessment for this population. In this framework, the unique challenges posed by a diagnosis of PPA are addressed with the aim to provide practical guidance for clinicians and to support reflection on current practices. METHOD: In clinical and research practice, assessment of people with PPA requires an ever-evolving approach that is centered on the client. In this clinical focus article, a discussion-based consensus process was used to synthesize authentic longitudinal experiences of people with PPA to explore assessment approaches, tools, and philosophies. RESULTS: This analysis of person-centered assessment identifies seven essential components of assessment in PPA that set the foundation for the five steps of the R.A.I.S.E. Assessment framework. These components each contribute to a clear definition of assessment that reveals clients' competencies with a strengths-based focus; prioritizes the reciprocity of benefits; promotes dynamic assessment; and recognizes the complexity, evolution of assessment over time, and advocacy. CONCLUSIONS: This clinical focus article takes a novel look at assessment in PPA by stepping away from assessment practices that focus on revealing deficits and decline and, instead, provides practical recommendations through the conceptualization of a PPA-specific assessment framework. The R.A.I.S.E. Assessment framework is grounded in principles of uplifting clients through person-centered assessment, keeps pace with best practice in PPA intervention, and contributes to a supportive experience for clients and families in the face of a progressive diagnosis over time.

Measuring communication as a core outcome in aphasia trials: Results of the ROMA-2 international core outcome set development meeting.

BACKGROUND: Evidence-based recommendations for a core outcome set (COS; minimum set of outcomes) for aphasia treatment research have been developed (the Research Outcome Measurement in Aphasia-ROMA, COS). Five recommended core outcome constructs: communication, language, quality of life, emotional well-being and patient-reported satisfaction/impact of treatment, were identified through three international consensus studies. Constructs were paired with outcome measurement instruments (OMIs) during an international consensus meeting (ROMA-1). Before the current study (ROMA-2), agreement had not been reached on OMIs for the constructs of communication or patient-reported satisfaction/impact of treatment. AIM: To establish consensus on a communication OMI for inclusion in the ROMA COS. METHODS & PROCEDURES: Research methods were based on recommendations from the Core Outcome Measures in Effectiveness Trials (COMET) Initiative. Participants with expertise in design and conduct of aphasia trials, measurement instrument development/testing and/or communication outcome measurement were recruited through an open call. Before the consensus meeting, participants agreed on a definition of communication, identified appropriate OMIs, extracted their measurement properties and established criteria for their quality assessment. During the consensus meeting they short-listed OMIs and participants without conflicts of interest voted on the two most highly ranked instruments. Consensus was defined a priori as agreement by ≥ 70% of participants. OUTCOMES & RESULTS: In total, 40 researchers from nine countries participated in ROMA-2 (including four facilitators and three-panel members who participated in pre-meeting activities only). A total of 20 OMIs were identified and evaluated. Eight short-listed communication measures were further evaluated for their measurement properties and ranked. Participants in the consensus meeting (n = 33) who did not have conflicts of interest (n = 29) voted on the top two ranked OMIs: The Scenario Test (TST) and the Communication Activities of Daily Living-3 (CADL-3). TST received 72% (n = 21) of 'yes' votes and the CADL-3 received 28% (n = 8) of 'yes' votes. CONCLUSIONS & IMPLICATIONS: Consensus was achieved that TST was the preferred communication OMI for inclusion in the ROMA COS. It is currently available in the original Dutch version and has been adapted into English, German and Greek. Further consideration must be given to the best way to measure communication in people with mild aphasia. Development of a patient-reported measure for satisfaction with/impact of treatment and multilingual versions of all OMIs of the COS is still required. Implementation of the ROMA COS would improve research outcome measurement and the quality, relevance, transparency, replicability and efficiency of aphasia treatment research. WHAT THIS PAPER ADDS: What is already known on this subject International consensus has been reached on five core constructs to be routinely measured in aphasia treatment studies. International consensus has also been established for OMIs for the three constructs of language, quality of life and emotional well-being. Before this study, OMIs for the constructs of communication and patient-reported satisfaction/impact of treatment were not established. What this paper adds to existing knowledge We gained international consensus on an OMI for the construct of communication. TST is recommended for inclusion in the ROMA COS for routine use in aphasia treatment research. What are the potential or actual clinical implications of this work? The ROMA COS recommends OMIs for a minimum set of outcomes for adults with post-stroke aphasia within phases I-IV aphasia treatment research. Although not intended for clinical use, clinicians may employ the instruments of the ROMA COS, considering the quality of their measurement properties. The systematic inclusion of a measure of communication, such as TST, in clinical practice could ultimately support the implementation of research evidence and best practices.

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

PURPOSE: Guidelines recommend routine discourse assessment and treatment in paediatric acquired brain injury (ABI) but provide little guidance for clinical practice. The degree to which this has influenced the nature of discourse assessment and treatment in clinical practice has not been examined in detail. METHOD: Speech-language pathologists working in paediatric ABI (clients aged <18 years) in Australia, New Zealand, the UK, the USA, Canada, and the Asia Pacific region were invited to complete a survey of discourse assessment and intervention practices (n = 77). RESULT: Clinicians from Australia and New Zealand comprised over half of a responses (53%). The largest proportion had over 10 years' experience (60%), worked in the metropolitan area (58%), and with secondary school-age children (64%). Routine discourse assessment was undertaken by 80% of respondents, focussing on a limited range of genres. No preferred intervention approach was identified. One-quarter of clinicians routinely considered holistic factors during clinical decision-making. Limited normative data and treatment evidence, insufficient time and training were identified as clinical barriers. CONCLUSION: Assessment practices were consistent with guidelines, yet interventions were highly variable, reflecting limited evidence, client heterogeneity, time constraints, and limited training. A biopsychosocial approach to practice was evident, yet a focus on impairment level factors was prominent. Findings support the need for standardised discourse assessment and discourse intervention methods. Translation into practice guidelines would promote consistency and confidence in clinical practice.

Treatment fidelity monitoring, reporting and findings in a complex aphasia intervention trial: a substudy of the Very Early Rehabilitation in SpEech (VERSE) trial.

BACKGROUND: Treatment fidelity is inconsistently reported in aphasia research, contributing to uncertainty about the effectiveness of types of aphasia therapy following stroke. We outline the processes and outcomes of treatment fidelity monitoring in a pre-specified secondary analysis of the VERSE trial. METHODS: VERSE was a 3-arm, single-blinded RCT with a 12-week primary endpoint comparing Usual Care (UC) to two higher intensity treatments: Usual Care-Plus (UC-Plus) and VERSE, a prescribed intervention. Primary outcome results were previously reported. This secondary analysis focused on treatment fidelity. Video-recorded treatment sessions in the higher intensity study arms were evaluated for treatment adherence and treatment differentiation. Treatment components were evaluated using a pre-determined fidelity checklist. PRIMARY OUTCOME: prescribed amount of therapy time (minutes); secondary outcomes: (i) adherence to therapy protocol (%) and (ii) treatment differentiation between control and high intensity groups. RESULTS: Two hundred forty-six participants were randomised to Usual Care (n=81), Usual Care-Plus (n=82), and VERSE (n=83). One hundred thirty-five (82%) participants in higher intensity intervention arms received the minimum prescribed therapy minutes. From 10,805 (UC 7787; UC-Plus 1450; VERSE 1568) service events, 431 treatment protocol deviations were noted in 114 participants. Four hundred thirty-seven videos were evaluated. The VERSE therapists achieved over 84% adherence to key protocol elements. Higher stroke and aphasia severity, older age, and being in the UC-Plus group predicted more treatment deviations. CONCLUSIONS: We found high levels of treatment adherence and differentiation between the intervention arms, providing greater confidence interpreting our results. The comprehensive systems for intervention fidelity monitoring and reporting in this trial make an important contribution to aphasia research and, we argue, should set a new standard for future aphasia studies.

Montessori mealtimes for dementia: A pathway to person-centred care.

PURPOSE: This study examined the impact of a Montessori mealtime intervention for people living with dementia to support the mealtime experience of residents and mealtime care practices of staff in a memory support unit. The mealtime intervention was part of a broader culture change project. METHOD: An observational research design was used to evaluate changes in the mealtime experience and care practices across three time points (baseline, post-implementation, maintenance), spanning 30 months. Five video recordings of the lunch time service (range: 19-32 min) were analysed. The coding protocol comprised pre-determined indicators related to accepted dimensions of person-centred care. Resident and staff behaviours were quantified across four categories: providing choice and preferences, promoting the social side of eating, supporting independence and showing respect towards residents. Staff behaviours that reflected personal enhancing actions and personal detractors were also coded during each mealtime service. RESULTS: A significant increase in staff providing residents with the opportunity for choice and a subsequent significant increase in residents demonstrating choice behaviours was evident. Staff and residents both significantly increased their interactional behaviours, with greater social interaction between staff and residents. Staff further demonstrated greater support for mealtime independence that reached and maintained significance during the final two sampling points. Significant gains observed post implementation were largely maintained and, on specific measures, further increased over time. A significant increase in staff use of personal enhancing actions during mealtime care was also evident. Variability in individual staff and resident behaviour highlighted the complexity of mealtime care and culture change processes. IMPLICATIONS: The study provides novel evidence to support the use of a Montessori mealtime intervention to achieve more person-centred mealtime care, and which resulted in a more respectful, enabling and social dining experience. Clinical implications and direction for future research are presented to build on these findings.

Making the Right Connections: Maximizing Lexical Generalization in Lexical Impairments in Primary Progressive Aphasia and Alzheimer's Disease.

Purpose Positive intervention effects following lexical retrieval interventions are increasingly reported with people with progressive language impairments; however, generalization of therapy gains are less frequently evident and less well understood. This study sought to explore the impact of specific therapy ingredients on generalization outcomes. Method Twelve participants with progressive lexical retrieval deficits (four each with semantic variant primary progressive aphasia, logopenic variant primary progressive aphasia, and Alzheimer's disease, amnestic presentation) and their family members participated in a 6-week intervention that aimed to increase access to different word classes (nouns, verbs, and adjectives) through a strategic self-cueing approach. Generalization was actively facilitated through strategy practice in connected speech. Repeated baselines of picture naming and connected speech were conducted prior to intervention and repeated immediately post and at 6 weeks following intervention. Results All three diagnostic groups showed significant improvements in naming performance post-intervention for all word classes and for both treated and untreated items, demonstrating consistent treatment effectiveness and generalization at the word level. No changes in the informativeness or efficiency of connected speech were found. Conclusions Despite heterogeneity across participants, widespread evidence of both treatment effects and generalization to untreated items was found for all diagnostic groups and word classes. The consistent within-level generalization across all groups is explored here in relation to optimization of strategy use through incorporation of cognitive scaffolds, strategic practice at the connected speech level, and the inclusion of family members. The absence of across-level generalization to connected speech is also explored. Supplemental Material https://doi.org/10.23641/asha.14219771.

The influence of genre on adolescent discourse skills: Do narratives tell the whole story?

Purpose: Narrative is the dominant focus of traditional standardised discourse assessment, yet the complex discourse needs of adolescence has led to increased interest in profiling skills in other monologic genres for this age group. This interest is not commensurate with a robust understanding of the influence of genre on adolescent discourse across word to whole-text language features. This knowledge is important to inform context(s) for assessment to profile strengths and weaknesses in discourse-level language.Method: One hundred and sixty adolescents between 12 and 15 years (M= 13;1, SD= 1;1, 55% female, 45% male) completed the Curtin University Discourse Protocol - Adolescent. Samples of recount, narrative, expository and persuasive discourse were coded using a multi-level analysis procedure.Result: Genre had a significant influence on language variables regardless of age. Narrative tasks citied the longest, most lexically diverse, cohesive, coherent and well-structured output. Results were consistent with the oral to literate continuum and the order in which genres are introduced in the academic curriculum.Conclusion: Structure, content and domain-specific knowledge likely influenced the genre-related differences seen in this study. It would be advantageous to sample a range of monologic genres when assessing adolescent discourse. Declarative knowledge may be an important consideration in topic selection.

Profiling variability and development of spoken discourse in mainstream adolescents.

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

A randomized control trial of intensive aphasia therapy after acute stroke: The Very Early Rehabilitation for SpEech (VERSE) study.

BACKGROUND: Effectiveness of early intensive aphasia rehabilitation after stroke is unknown. The Very Early Rehabilitation for SpEech trial (VERSE) aimed to determine whether intensive aphasia therapy, beginning within 14 days after stroke, improved communication recovery compared to usual care. METHODS: Prospective, randomized, single-blinded trial conducted at 17 acute-care hospitals across Australia/New Zealand from 2014 to 2018. Participants with aphasia following acute stroke were randomized to receive usual care (direct usual care aphasia therapy), or one of two higher intensity regimens (20 sessions of either non-prescribed (usual care-plus or prescribed (VERSE) direct aphasia therapy). The primary outcome was improvement of communication on the Western Aphasia Battery-Revised Aphasia Quotient (AQ) at 12 weeks after stroke. Our pre-planned intention to treat analysis combined high intensity groups for the primary outcome. FINDINGS: Among 13,654 acute stroke patients screened, 25% (3477) had aphasia, of whom 25% (866) were eligible and 246 randomized to usual care (n = 81; 33%), usual care-plus (n = 82; 33%) or VERSE (n = 83; 34%). At 12 weeks after stroke, the primary outcome was assessed in 217 participants (88%); 14 had died, 9 had withdrawn, and 6 were too unwell for assessment. Communication recovery was 50.3% (95% CI 45.7-54.8) in the high intensity group (n = 147) and 52.1% (95% CI 46.1-58.1) in the usual care group (n = 70; difference -1.8, 95% CI -8.7-5.0). There was no difference between groups in non-fatal or fatal adverse events (p = 0.72). INTERPRETATION: Early, intensive aphasia therapy did not improve communication recovery within 12 weeks post stroke compared to usual care.

"I remember when ": The impact of reminiscence therapy on discourse production in older adults with cognitive impairment.

Purpose: Positive outcomes following reminiscence therapy have been reported for older adults with mild cognitive impairment and dementia in cognition and quality of life and, in a small number of studies, communication. Despite the close relationship between cognition and language, the impact on communication has received limited attention. This study aimed to investigate whether the spoken discourse of older adults with mild cognitive impairment or dementia could be improved within the genre of nostalgic recounts following group reminiscence therapy, and whether change generalised to everyday discourse.Method: Four females (mean: 87 years, SD: 7.3) who lived in a residential aged care facility and were diagnosed with mild (n = 2) or major (n = 2) neurocognitive impairment were recruited to attend a group reminiscence programme delivered in eight one-hour treatment sessions over four weeks. Multiple baseline samples of discourse were obtained in the week prior to intervention to monitor stability. Macrostructure, rate, informativeness and efficiency of discourse production were measured to identify change within nostalgic recounts and monitor evidence of generalised change in everyday discourse genres. Cognitive performance and quality of life were also monitored.Result: While variability was evident, significant increases in macrostructure and richness of nostalgic recounts were found for two participants, with significant generalisation to everyday discourse. Both participants had diagnoses of mild cognitive impairment. No significant improvements were seen in cognition or quality of life with all participants.Conclusion: This study provides promising evidence for the spoken recall of memories having the potential to improve the communication of people with neurocognitive disorders, with some indication that people with milder impairment may be more amenable to this form of intervention. Nostalgic recounts may provide an explicit context in which speech-language pathologists can facilitate the planning of spoken production in people with cognitive impairment, and influence speaking in everyday contexts.

Exploring the Viability of NARNIA with Cognitive-Communication Difficulties: A Pilot Study.

Everyday discourse is a common context for the difficulties experienced by people with acquired neurogenic communication disorders. While evidence is present for effective manualized interventions that directly improve the discourse skills in aphasia, this remains limited for people with cognitive-communication disorders. This proof of concept study used an in-depth case series approach to trial the NARNIA discourse intervention used successfully in aphasia to explore transferability of the protocol and effectiveness in people with cognitive-communication impairments. Four female participants with mild to moderate cognitive-communication difficulties (mean age: 52.8 years)-two following traumatic brain injury and two following vascular episodes-were recruited. Modifications were made to the protocol to accommodate the participant group. Cognitive-linguistic abilities, self-perceptions of communicative behavior and psychosocial recovery, and repeated discourse measures were assessed pre-, immediately post, and at 4 weeks following intervention, to measure treatment effectiveness. Significant gains were observed in quantity of output, informativeness, and efficiency of information across both everyday and narrative discourse genres for all participants. However, in contrast to previous studies, minimal change was observed in discourse macrostructure elements. Significant improvements were also observed in memory or working memory for two participants. This study provides preliminary evidence for the effectiveness of using an adapted protocol with people with cognitive-communication disorders, highlighting how adaptations may address the cognitive needs of this diverse clinical group.

Lost for words: Perspectives and experiences of people with primary progressive aphasia and Alzheimer's disease and their families of participation in a lexical retrieval intervention.

Purpose: Previous qualitative research involving family members' experiences of living with a person with dementia has consistently revealed themes of reduced connectedness and reciprocity of communication, highlighting the importance of education, support and practical strategies to facilitate communication within families. This study aimed to evaluate the perspectives and experiences of both family members and people with dementia following participation in a targeted speech-language pathology intervention involving people with primary progressive aphasia (PPA) and Alzheimer's disease (AD) and their family members. Method: Semi-structured interviews of eight people with dementia (six PPA, two AD) and 10 family members were conducted following an intervention to increase lexical retrieval within functional contexts. Thematic analysis was used to analyse the interview transcripts. Result: Two themes common to participants with dementia and family members emerged: (1) perceived benefits of the intervention and (2) lack of previous information on communication difficulties. Two separate themes emerged for people with dementia, predominantly people with PPA, involving: (1) improved communication and (2) increased participation. Three separate themes emerged for family members: (1) increased awareness and knowledge, (2) increased value of interaction and engagement and (3) uncertainty of the future. Conclusion: The findings of this qualitative study revealed a range of perspectives on the experiences of client and family participants following a communication focussed intervention, examining both the nature of perceived direct gains and gaining insight into the issues faced by these client populations and their families. The provision of individualised information and education should be a fundamental human right for all people with communication impairment with greater attention given to people with progressive conditions where such needs are not currently met.

Profiling sentence repetition deficits in primary progressive aphasia and Alzheimer's disease: Error patterns and association with digit span.

The use of sentence repetition tasks to distinguish dementia syndromes, particularly variants of primary progressive aphasia (PPA), is receiving growing attention. Impaired sentence repetition is a core feature of logopenic variant PPA, although the underlying cognitive mechanisms of this impairment and its significance as a diagnostic criterion remain poorly understood. Sentence repetition abilities of 12 people with dementia, using an adapted error classification schema, were analyzed, along with digit span abilities, a measure frequently used to assess working memory capacity, to explore error patterns and correlations. Participants with semantic variant PPA showed the greatest performance on sentence repetition and digit span in comparison to the logopenic variant PPA and Alzheimer's disease participants. Sentence repetition errors were characterized by middle omissions for semantic variant PPA, ending omissions and phonological errors for logopenic variant PPA, and ending omissions and unrelated word substitutions for Alzheimer's disease. Significant correlations were found between sentence repetition and digit span abilities. Findings are discussed in relation to working memory capacity theories, specifically, the dual-component model.

Statistical analysis plan (SAP) for the Very Early Rehabilitation in Speech (VERSE) after stroke trial: an international 3-arm clinical trial to determine the effectiveness of early, intensive, prescribed, direct aphasia therapy.

Background Limited evidence exists to support very early intensive aphasia rehabilitation after stroke. VERSE is a PROBE trial designed to determine whether two types of intensive aphasia therapy, beginning within 14 days of acute stroke, provide greater therapeutic and cost-effectiveness than usual care. Objective To publish the detailed statistical analysis plan for the VERSE trial prior to unblinding. This statistical analysis plan was based on the published and registered VERSE trial protocol and was developed by the blinded steering committee and management team, led by the trial statistician. This plan was developed using outcome measures and trial data collection forms. Results The VERSE statistical analysis plan is consistent with reporting standards for clinical trials and provides for clear and open reporting. Conclusions Publication of a statistical analysis plan serves to reduce potential trial reporting bias and outlines transparent pre-specified analyses. Australian New Zealand Clinical Trials Registry (ANZCTR) Registration number: ACTRN12613000776707; Universal Trial Number (UTN) is U1111-1145-4130.

Discourse and cognition in speakers with acquired brain injury (ABI): a systematic review.

BACKGROUND: Cognitive impairment, particularly of executive functioning, has been implicated in deficits in spoken discourse production following acquired brain injury (ABI). However, due to variation in the methodologies and heterogeneity of findings across studies, the nature and extent of this association is not well understood. AIMS: This review aims to synthesize the literature investigating associations between cognitive deficits and discourse impairment after ABI. It is reported in accordance with guidelines of The Preferred Reporting Items of Systematic Reviews and Meta-Analyses. DATA SOURCES: Searches were conducted of a variety of databases including Medline, PsycINFO, EMBASE, CINAHL, ProQuest, Cochrane and ERIC. Additional studies were identified via reference harvesting. ELIGIBILITY CRITERIA: Studies were included if they reported data on participants with ABI, assessed spoken discourse production and cognitive function, and performed statistical analyses to determine the association between discourse and cognitive variables. This review excluded non-English sources and those not published in peer-reviewed journals. Meta-analyses were not conducted due to variability across tools and terminology used to describe participant injury- and non-injury-related characteristics and outcomes. RESULTS: Twenty-five observational studies were included in the review. Findings revealed significant associations between multiple cognitive functions and discourse across micro-linguistic to super-structural measures. Methodological and terminological inconsistencies were identified across studies, which limited systematic comparison of the results. CONCLUSIONS: This review revealed present, yet heterogeneous, relationships between cognitive and discourse deficits in speakers with ABI. Associations were interpreted in light of a well-established model of discourse processing. Greater comparison across studies would have been facilitated by a standard nomenclature in relation to cognitive constructs and standardized discourse assessment. Future research should explore the influence of injury- and participant-related factors on discourse-cognitive relationships. The lack of information on conversational discourse and paediatric ABI limits the generalizability of this review to daily interaction following ABI. While applicable across the lifespan, in-depth investigation of discourse following ABI in childhood and adolescence is a priority due to complex changes in language and cognition, and the potential for impairments profoundly impact social, emotional and academic progression into adulthood. Given the centrality of remediating cognitive-communication difficulties in ABI, the interrelationships between discourse and cognition should retain a critical focus of research. This will inform clinical management and future research with this population. Findings have implications for our theoretical understanding of discourse and the nature of its breakdown in ABI.

Determining stability in connected speech in primary progressive aphasia and Alzheimer's disease.

PURPOSE: Using connected speech to assess progressive language disorders is confounded by uncertainty around whether connected speech is stable over successive sampling, and therefore representative of an individual's performance, and whether some contexts and/or language behaviours show greater stability than others. METHOD: A repeated measure, within groups, research design was used to investigate stability of a range of behaviours in the connected speech of six individuals with primary progressive aphasia and three individuals with Alzheimer's disease. Stability was evaluated, at a group and individual level, across three samples, collected over 3 weeks, involving everyday monologue, narrative and picture description, and analysed for lexical content, fluency and communicative informativeness and efficiency. RESULT: Excellent and significant stability was found on the majority of measures, at a group and individual level, across all genres, with isolated measures (e.g. nouns use, communicative efficiency) showing good, but greater variability, within one of the three genres. CONCLUSION: Findings provide evidence of stability on measures of lexical content, fluency and communicative informativeness and efficiency. While preliminary evidence suggests that task selection is influential when considering stability of particular connected speech measures, replication over a larger sample is necessary to reproduce findings.

Dysphagia therapy post stroke: An exploration of the practices and clinical decision-making of speech-language pathologists in Australia.

PURPOSE: A variety of dysphagia management options are available for the treatment of dysphagia following a stroke, however, it is unknown which of these approaches are most commonly utilised by Australian speech-language pathologists (SLPs) and whether particular factors influence decision-making. METHOD: The aim of this study was to investigate, through an online survey, the treatment practices of SLPs in Australia for the treatment of dysphagia post-stroke and identify the factors influencing treatment decisions. RESULT: A total of 118 SLPs completed the online survey. Descriptive statistics identified large variability in the dysphagia treatments utilised, with all 24 therapies listed in the online survey reported as being routinely used. Compensatory therapies were ranked as being utilised more frequently than rehabilitative approaches, with six of the seven highly utilised therapies being compensatory in nature. A client's cognitive capacity was the most prominent factor influencing SLPs' treatment decisions. CONCLUSION: This study provides insight into the practices of SLPs in Australia for the treatment of dysphagia following stroke and discusses potential for shifts in practice. It highlights the complexity involved in the decision-making process and that clinicians consider evidence, as well as client, clinician and service factors, when selecting between the range of options available.
