Person-centered care for people with aphasia: tools for shared decision-making.

Shared decision-making is a fundamental aspect of person-centered care, and can and should be part of many different aspects of the rehabilitation process. Communication disabilities like aphasia, which affects people's ability to use and understand spoken and written language, can make shared decision-making especially challenging to the resources and skills of rehabilitation practitioners. The purpose of this narrative review is to provide a comprehensive description of tools that can support successful shared decision-making with people with aphasia in the rehabilitation environment. These tools and strategies are appropriate for use by physicians, nurses, social workers, physical therapists (also referred to as physiotherapists), occupational therapists, and other service or care providers. The important role of speech-language pathologists as consultants is also described. Case scenarios throughout the paper illustrate the application of recommended tools and strategies along with best practices.

Treatment Time and Treatment Selection in Aphasia: A Preliminary Study Using Vignettes.

PURPOSE: Little is known about the factors that clinicians use when selecting treatments. The purpose of this preliminary study was to explore a possible factor, available treatment time, in the aphasia treatment selection process. METHOD: A case-based vignette survey was created using de-identified assessment data from the AphasiaBank database. Six vignettes varied by aphasia type and severity and were presented under two different treatment time alternatives: 7.5 or 60 hr. Respondents were asked to select the single treatment that they would "almost certainly use" under each treatment time scenario. Treatment options were obtained from the American Speech-Language-Hearing Association Practice Portal. Respondents also answered questions about their confidence level in administering the treatments and their primary reason for selecting a particular treatment for each case scenario. RESULTS: A total of 26 practicing speech-language pathologists with at least 5 years of clinical experience with aphasia completed the survey. A majority of respondents (76%-84%) changed the treatment they would "almost certainly use" based on a change in treatment time availability. The most frequently given reason for the overall treatment selection was that the treatment was likely to produce a functional outcome. Neither the respondents' reported confidence levels nor their years of experience were related to treatment selection. CONCLUSIONS: This is one of the first studies to investigate how clinicians select aphasia treatment. Treatment time emerged as a consistent factor in selecting aphasia treatment in this preliminary study. Recommendations for next research steps are given. We suggest that aphasia treatment research be disseminated with clear information about required treatment time. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.23646855.

Why and how to publish aphasia-friendly research summaries.

BACKGROUND: A common complaint of people with aphasia and their families is their inability to find information about current aphasia treatment research (Hinckley, Boyle, Lombard & Bartels-Tobin, 2014; Hinckley & El-Khouri, 2021). Plain language summaries, video summaries, and graphical summaries are three ways to disseminate research results that are more accessible to a broader audience. The purpose of this tutorial is to discuss the motivations for disseminating research in understandable ways, and to provide information and resources on how aphasia-friendly dissemination can be done. METHOD: We report an overview of evidence on the importance of and characteristics of dissemination. Next, we provide specific characteristics and resources for producing plain language summaries, video summaries, and graphical abstracts. Finally, we conducted a systematic search for journals in the area of stroke rehabilitation after consultation with a research librarian. The publication webpages of each journal were inspected to gather information about whether and how the journal published plain language summaries, video summaries, or graphical abstracts. Editors were contacted as needed to complete the information. Sixty journals in stroke rehabilitation were identified, and a total of 43 journals (71%) publish video abstracts, graphical summaries, and/or plain language summaries either independently or through third-party platforms. CONCLUSIONS: The findings are discussed in the context of the importance of making research consumer-friendly. We offer specific recommendations for aphasia researchers, and future directions for publishing research in ways that will have an impact on the broader public are suggested.

How a Power Differential Between Clinicians and Researchers Contributes to the Research-to-Practice Gap.

PURPOSE: The purpose of this article is to contend that there is a power differential between researchers and clinicians where researchers are the primary creators of knowledge and clinicians are the primary consumers of knowledge. Rooted in a sociological model illustrating interacting levels of power at macro-, meso-, and microlevels, we argue that authentic research-practice partnerships and clinician-researcher collaborations can mitigate this power differential. CONCLUSIONS: Clinicians and researchers in our field have vastly different responsibilities and priorities that impact our ability to work collaboratively to solve the most pressing problems for the clients we serve. Although some current research practices may reinforce a power differential causing clinicians to feel less than and to only consume knowledge, there are examples of successful collaborations where this power differential is mitigated. These examples can contribute meaningfully to the dialogue on research-practice partnerships, with the goal of improving outcomes for the clients we serve.

Replication in Evidence-Based Aphasia Treatments.

PURPOSE: A critical review was completed to evaluate replication of aphasia treatments that have been vetted and accepted on the American Speech-Language-Hearing Association Practice Portal. METHOD: The electronic databases Academic Search Premier, ProQuest Central, CINAHL Complete, and ERIC were searched for relevant articles using treatment names as keywords. Coders compared stimuli, material, design, and statistical analysis to pilot treatment approaches. Each study was coded as direct, conceptual, failed, or no replication. RESULTS: Eighteen treatment approaches were selected for this review. A total of 188 articles met the inclusion criteria. Results revealed that 14 out of 18 treatment approaches were somehow replicated. Direct replications as the most valuable replication type for affirming previously found results were represented in only 1.5% of all studies (3/188). Failed direct replication were at 2% overall (4/188). Conceptual replications were more common across treatment approaches, but also represented at a low level with 22.8% (43/188). The majority of studies were coded as no replication attempt with 73.4%. DISCUSSION: A critical factor in developing an evidence-based practice is the existence of replicated results for treatment. Replication evaluates the reproducibility of an author's or authors' research methodology and resulting outcomes and helps to ensure that observed treatment effects are reproducible. For an evidence-based treatment to be implemented or used in any clinical setting, it must be one that can be replicated. Direct and conceptual replications of aphasia treatment approaches were found to be alarmingly low considering the importance of replication in our field. It is recommended that replication should become more valued and mainstreamed in aphasia research. A replication database that compiles and maintains treatment manuals for replication purposes can increase the accessibility and acceptability of replications for researchers.

Building Research Initiatives by Developing Group Effort (BRIDGE): Patient-Partners in Aphasia Research.

Researcher-initiated research often has little or no input from the groups who will be affected by the results of the research. The aim of this project was to describe practices of embracing patient-partners (i.e., individuals with aphasia and spouses/family members) in research. Six webinars were developed for both researchers and patient-partners that were required prior to participating in a joint conference that focused on collaborative research teams. The conference was designed based on an appreciative inquiry approach. Including patient-partners into research priorities and planning has been accomplished across various health domains in the United States, but this was the first organized national effort, in the United States, to support the inclusion of people with aphasia and their families as active partners in the research process. Consequently, it is hoped that future aphasia researchers also include patient-partner teams into their research process for more ecologically valid outcomes.

Applying linguistic demand analysis to functional multitasking assessments.

PURPOSE: The linguistic demand of task instructions in cognitive assessments may mask or even invalidate cognitive testing results for individuals with language differences or impairments. The purpose of this study was to apply an analysis of linguistic demand to a sample of functional multitasking assessments. METHOD: We sampled the task instructions and materials from seven functional multitasking assessments that are based on everyday activities. We calculated indices of linguistic demand. RESULTS: The Density Index is based on total number of words, total number of sentences, total number of different words, total number of syllables, and complex (not-simple) sentences. The Breakfast Task and the Frisch Cooking Task consistently ranked lowest in linguistic demand for both instructions and materials based on the indices reviewed. These tasks are most likely to be appropriate for individuals with language impairment. CONCLUSIONS: Clinicians have a responsibility to fairly evaluate cognitive functions of individuals with impaired language functioning. The analysis of linguistic demand provides a useful way to evaluate task instructions and materials in a systematic way, so that individuals with language impairments or language differences might be more appropriately evaluated.

Precision rehabilitation for aphasia by patient age, sex, aphasia severity, and time since stroke? A prespecified, systematic review-based, individual participant data, network, subgroup meta-analysis.

BACKGROUND: Stroke rehabilitation interventions are routinely personalized to address individuals' needs, goals, and challenges based on evidence from aggregated randomized controlled trials (RCT) data and meta-syntheses. Individual participant data (IPD) meta-analyses may better inform the development of precision rehabilitation approaches, quantifying treatment responses while adjusting for confounders and reducing ecological bias. AIM: We explored associations between speech and language therapy (SLT) interventions frequency (days/week), intensity (h/week), and dosage (total SLT-hours) and language outcomes for different age, sex, aphasia severity, and chronicity subgroups by undertaking prespecified subgroup network meta-analyses of the RELEASE database. METHODS: MEDLINE, EMBASE, and trial registrations were systematically searched (inception-Sept2015) for RCTs, including ⩾ 10 IPD on stroke-related aphasia. We extracted demographic, stroke, aphasia, SLT, and risk of bias data. Overall-language ability, auditory comprehension, and functional communication outcomes were standardized. A one-stage, random effects, network meta-analysis approach filtered IPD into a single optimal model, examining SLT regimen and language recovery from baseline to first post-intervention follow-up, adjusting for covariates identified a-priori. Data were dichotomized by age (⩽/> 65 years), aphasia severity (mild-moderate/ moderate-severe based on language outcomes' median value), chronicity (⩽/> 3 months), and sex subgroups. We reported estimates of means and 95% confidence intervals. Where relative variance was high (> 50%), results were reported for completeness. RESULTS: 959 IPD (25 RCTs) were analyzed. For working-age participants, greatest language gains from baseline occurred alongside moderate to high-intensity SLT (functional communication 3-to-4 h/week; overall-language and comprehension > 9 h/week); older participants' greatest gains occurred alongside low-intensity SLT (⩽ 2 h/week) except for auditory comprehension (> 9 h/week). For both age-groups, SLT-frequency and dosage associated with best language gains were similar. Participants ⩽ 3 months post-onset demonstrated greatest overall-language gains for SLT at low intensity/moderate dosage (⩽ 2 SLT-h/week; 20-to-50 h); for those > 3 months, post-stroke greatest gains were associated with moderate-intensity/high-dosage SLT (3-4 SLT-h/week; ⩾ 50 hours). For moderate-severe participants, 4 SLT-days/week conferred the greatest language gains across outcomes, with auditory comprehension gains only observed for ⩾ 4 SLT-days/week; mild-moderate participants' greatest functional communication gains were associated with similar frequency (⩾ 4 SLT-days/week) and greatest overall-language gains with higher frequency SLT (⩾ 6 days/weekly). Males' greatest gains were associated with SLT of moderate (functional communication; 3-to-4 h/weekly) or high intensity (overall-language and auditory comprehension; (> 9 h/weekly) compared to females for whom the greatest gains were associated with lower-intensity SLT (< 2 SLT-h/weekly). Consistencies across subgroups were also evident; greatest overall-language gains were associated with 20-to-50 SLT-h in total; auditory comprehension gains were generally observed when SLT > 9 h over ⩾ 4 days/week. CONCLUSIONS: We observed a treatment response in most subgroups' overall-language, auditory comprehension, and functional communication language gains. For some, the maximum treatment response varied in association with different SLT-frequency, intensity, and dosage. Where differences were observed, working-aged, chronic, mild-moderate, and male subgroups experienced their greatest language gains alongside high-frequency/intensity SLT. In contrast, older, moderate-severely impaired, and female subgroups within 3 months of aphasia onset made their greatest gains for lower-intensity SLT. The acceptability, clinical, and cost effectiveness of precision aphasia rehabilitation approaches based on age, sex, aphasia severity, and chronicity should be evaluated in future clinical RCTs.

RELEASE: a protocol for a systematic review based, individual participant data, meta- and network meta-analysis, of complex speech-language therapy interventions for stroke-related aphasia.

Background: Speech and language therapy (SLT) benefits people with aphasia following stroke. Group level summary statistics from randomised controlled trials hinder exploration of highly complex SLT interventions and a clinically relevant heterogeneous population. Creating a database of individual participant data (IPD) for people with aphasia aims to allow exploration of individual and therapy-related predictors of recovery and prognosis. Aim: To explore the contribution that individual participant characteristics (including stroke and aphasia profiles) and SLT intervention components make to language recovery following stroke. Methods and procedures: We will identify eligible IPD datasets (including randomised controlled trials, non-randomised comparison studies, observational studies and registries) and invite their contribution to the database. Where possible, we will use meta- and network meta-analysis to explore language performance after stroke and predictors of recovery as it relates to participants who had no SLT, historical SLT or SLT in the primary research study. We will also examine the components of effective SLT interventions. Outcomes and results: Outcomes include changes in measures of functional communication, overall severity of language impairment, auditory comprehension, spoken language (including naming), reading and writing from baseline. Data captured on assessment tools will be collated and transformed to a standardised measure for each of the outcome domains. Conclusion: Our planned systematic-review-based IPD meta- and network meta-analysis is a large scale, international, multidisciplinary and methodologically complex endeavour. It will enable hypotheses to be generated and tested to optimise and inform development of interventions for people with aphasia after stroke. Systematic review registration: The protocol has been registered at the International Prospective Register of Systematic Reviews (PROSPERO; registration number: CRD42018110947).

Aphasia Practice in the Year 2026.

The purpose of this article is to envision how the clinical practice of aphasia management might be done 10 years in the future. The vision of how an individual clinician's daily tasks are changed is built on current trends, including the aging of the population, the life participation approach to aphasia, development and use of evidence-based practices, person-centered care, and technology. To be prepared for the future of these trends, we will need to develop clinical capacity, not only in the number of speech-language pathologists but also most importantly in their competence for using evidence-based practices and training others to support effective communication, including other health care providers. Research needs that will support the future are also described.

Implementation Science: Buzzword or Game Changer?

PURPOSE: The purpose of this supplement article is to provide a resource of pertinent information concerning implementation science for immediate research application in communication sciences and disorders. METHOD: Key terminology related to implementation science is reviewed. Practical suggestions for the application of implementation science theories and methodologies are provided, including an overview of hybrid research designs that simultaneously investigate clinical effectiveness and implementation as well as an introduction to approaches for engaging stakeholders in the research process. A detailed example from education is shared to show how implementation science was utilized to move an intervention program for autism into routine practice in the public school system. In particular, the example highlights the value of strong partnership among researchers, policy makers, and frontline practitioners in implementing and sustaining new evidence-based practices. CONCLUSIONS: Implementation science is not just a buzzword. This is a new field of study that can make a substantive contribution in communication sciences and disorders by informing research agendas, reducing health and education disparities, improving accountability and quality control, increasing clinician satisfaction and competence, and improving client outcomes.

Perceptions of speech-language pathologists linked to evidence-based practice use in skilled nursing facilities.

PURPOSE: This study explored whether perceptions of evidence or organizational context were associated with the use of external memory aids with residents with dementia in skilled nursing facilities (SNFs). METHOD: A survey design, supplemented by a small sample of exploratory interviews, was completed within the Promoting Action on Research Implementation in Health Services framework. Ninety-six speech-language pathologists (SLPs) and 68 facility rehabilitation directors (FRDs) completed the Organizational Readiness to Change Assessment (Helfrich, Li, Sharp, & Sales, 2009) in relationship to the use of external memory aids. Five SLPs completed an interview exploring perceptions of evidence and context in relationship to memory aid use. RESULTS: SLPs and FRDs had favorable perceptions of evidence supporting memory aids. FRDs perceived the organizational context of the SNF more favorably than SLPs. SLP participants used external memory aids in the past 6 months in 45.89% of cases of residents with dementia. For SLP participants, a 26% (p < .05) increase of external memory aid use was associated with every 1-unit change in favor of the evidence. Interview data revealed barriers to external memory aid implementation. CONCLUSIONS: Part of evidence-based practice implementation may be influenced by clinician perceptions. Efforts to increase implementation of external memory aids in SNFs should address these clinician perceptions.

Towards a consumer-informed research agenda for aphasia: preliminary work.

PURPOSE: Person-centeredness in clinical practice incorporates the values of clients into a shared decision-making approach. The values of person-centeredness can be extended into the realm of research when the views of consumers towards relevant and important research topics are sought. Work in other health domains has shown the importance of gathering consumer views on health care research, which ultimately extends into health care policy and practice. The purpose of this paper is to report methods used successfully to gather the views of individuals living with aphasia on research topics they view as important. METHODS: The project is founded on principles of community-based participatory research. Using a modified nominal group technique, members of an aphasia support group generated a list of research topics. RESULTS: The Aphasia Support Group identified twenty-two potential research questions. Although a majority (59%) of the research questions generated by persons with aphasia could be addressed with accumulated scientific evidence, the remainder of the generated questions has not been addressed in the research literature. CONCLUSIONS: This project demonstrates that consumers with aphasia can participate as stakeholders in the discussion of research needs in aphasia. Additional work is needed to fully develop a consumer-informed research agenda for aphasia. IMPLICATIONS FOR REHABILITATION: The perspectives of individuals with post-stroke aphasia on research needs can be successfully collected using nominal group techniques. Consumer input to research agendas and priorities can help to address potential research biases. Clinicians and researchers can use these techniques and other communication supports to foster collaborative, patient-centered care in their practice and work.

A case for the implementation of cognitive-communication screenings in acute stroke.

PURPOSE: The purpose of this article was to illustrate the importance of the implementation of cognitive-communication screenings in acute stroke and to discuss the need for further research on whether and how these screenings are implemented. Cognitive-communication screenings after stroke are the subject of existing practice guidelines and are supported by accumulated evidence. METHOD: The author uses an autoethnographic narrative--a tool founded in phenomenology--to provide an in-depth description of the experiences of a family in which one member experienced right-hemispheric stroke. She uses systematic introspection to produce a narrative using literary techniques. RESULTS: The narrative illustrates the experiences of one family when one of their members has a right-hemisphere stroke, and cognitive-communication impairments are never formally identified by professionals involved in the patient's care. CONCLUSIONS: The narrative is linked to the published literature and the importance of identifying and managing cognitive-communication impairments after stroke. A model of implementation science is presented as one way to consider the challenges clinicians face when attempting to implement evidence-based practices. The model and examples from other fields show avenues for further research.

Treatment fidelity: its importance and reported frequency in aphasia treatment studies.

PURPOSE: Treatment fidelity is a measure of the reliability of the administration of an intervention in a treatment study. It is an important aspect of the validity of a research study, and it has implications for the ultimate implementation of evidence-supported interventions in typical clinical settings. METHOD: Aphasia treatment studies published in the last 10 years in 3 journals were reviewed using coding techniques that were adapted from Gresham, Gansle, Noell, Cohen, and Rosenblum (1993). The following items were noted: identifying information, study design, description of both the dependent and independent variables, and whether a measure of treatment fidelity was explicitly included. RESULTS: Of the aphasia treatment studies published in the last 10 years, 14% explicitly reported treatment fidelity. Most studies reporting treatment fidelity used checking of videotaped sessions by independent raters. Of the reviewed studies, 45% provided sufficient treatment description to support replication. CONCLUSION: Treatment fidelity is widely acknowledged as being critical to research validity and is a foundation for the implementation of evidence-based practices, but only a small percentage of aphasia treatment studies published in the last 10 years explicitly reported treatment fidelity. Recommendations for research practices include increased attention to matters of treatment fidelity in the peer review process and explicit incorporation of 3 levels of treatment fidelity in treatment research.

What people living with aphasia think about the availability of aphasia resources.

PURPOSE: Obtaining health information and resources can influence an individual's (a) access to services, (b) interactions with health care providers, and (c) ability to manage one's own health needs. The purpose of this study was to gather the perceptions of consumers living with aphasia about resource availability and information needs. METHOD: An online survey of consumers in the United States was conducted about the availability of aphasia resources. Analysis of survey responses and comments formed the basis for focus group questions. Four focus groups consisting of persons with aphasia and their caregivers were conducted to explore the survey response themes more deeply. RESULTS: Survey respondents (N   =   302) rated aphasia resources as "somewhat difficult to find." Topics ranked as most important by these respondents were (a) how to keep improving, (b) communication strategies, (c) aphasia treatment techniques, (d) coping strategies, and (e) strategies for caregivers. Survey comments and focus group themes suggested that accessing information is difficult, health care providers are not perceived to know about aphasia resources, and there is a lack of public awareness of aphasia that is a barrier to finding information and resources. CONCLUSION: Understanding how people living with aphasia seek information may allow us to better tailor access to resources in the future.

Neural correlates of semantic activation spreading on the path to picture naming in adults who stutter.

OBJECTIVE: On the path to picture naming, words that relate semantically to the pictured object become activated in the mental lexicon. We used a neuroscientific approach to investigate this semantic activation spreading process in adults who stutter (AWS). METHODS: Fourteen AWS and 14 adults who do not stutter (AWNS) completed a picture-word priming task. On each trial, a picture was named at a delay. On some trials, an unattended auditory probe word was presented after the picture, before naming commenced. Event-related potentials recorded to probe words Semantically-Related to the picture labels, and to probe words Semantically- and Phonologically-Unrelated to the picture labels, were compared using spatial-temporal principal component analysis. RESULTS: Posterior N400 amplitude was attenuated for Semantically-Related versus Unrelated probes in AWNS, while in AWS posterior N400 amplitude was enhanced for Semantically-Related versus Unrelated probes. Marginal albeit potentially relevant group differences in the morphology of other ERP components were also observed. CONCLUSIONS: The posterior N400 results point to a strategic, inhibitory influence on semantic activation spreading in AWS on the path to naming. Group differences in the amplitude of other ERP components tentatively suggest that AWS allocated attentional resources differently than the AWNS during the task. Preliminary ERP evidence of intact conceptual (as opposed to lexical-semantic) priming in the AWS is also discussed. SIGNIFICANCE: This study contributes to a growing body of research describing linguistic performance in AWS.

Hope for happy endings: stories of clients and clinicians.

In this introduction to the issue, it is asserted that a positive therapeutic relationship may be equally important to good rehabilitation outcomes as the administration of an effective, evidence-based treatment. The author illustrates this assertion with two variations of a clinical story in which aspects of the therapeutic relationship are manipulated. The narrative methodologies used in the articles in this issue, including ethnography, autoethnography, and personal narrative, are defined. Because details of the therapeutic relationship can best be explored through narrative methodologies, there will always be a role for narratives in the understanding of best clinical practice.
