Purpose: The purposes of this review article were to provide an introduction to and "bird's-eye" overview of the current evidence base for treatment of childhood apraxia of speech (CAS), identify some gaps and trends in this rapidly growing literature, and formulate some future research directions, in order to advance the evidence base and clinical practice for children with CAS. Method: Following a brief introduction outlining important concepts, a narrative review of the CAS treatment literature is provided, and trends and future directions are identified based on this review. The review is organized around four fundamental treatment research questions: (a) "Does Treatment X work?", (b) "Does Treatment X work better than Treatment Y?", (c) "For whom does Treatment X work?", and (d) "What does 'work' mean, anyway?" Results: A wide range of CAS treatments with varying degrees of evidence for efficacy exists. Research is beginning to emerge that compares different treatments and seeks to determine optimal treatment parameters. Few studies to date have explored child-level predictors of treatment response, and the evidence base currently is limited in scope with respect to populations and outcomes studied. Conclusions: A growing evidence base supports the efficacy of a number of treatments for CAS. However, many important gaps in the literature were identified that warrant redoubled and sustained research attention. Research is beginning to emerge that addresses treatment optimization, comparison, candidacy, and outcomes. Suggestions for future research are offered, and the concept of a hypothesized pathway was applied to CAS to illustrate how components of an intervention can effect change in a clinical goal and can help guide development and refinement of treatments for children with CAS.

This article introduces the Journal of Speech, Language, and Hearing Research Special Issue: Selected Papers From the 2022 Apraxia Kids Research Symposium. The field of childhood apraxia of speech (CAS) has developed significantly in the past 15 years, with key improvements in understanding of basic biology including genetics, neuroscience, and computational modelling; development of diagnostic tools and methods; diversity of evidence-based interventions with increasingly rigorous experimental designs; and understanding of impacts beyond impairment-level measures. Papers in this special issue not only review and synthesize the some of the substantial progress to date but also present novel findings addressing critical research gaps and adding to the overall body of knowledge. A second aim of this prologue is to report the current research needs in CAS, which arose from symposium discussions involving researchers, clinicians, and Apraxia Kids community members (including parents of children with CAS). Four primary areas of need emerged from discussions at the symposium. These were: (a) What questions should we ask? (b) Who should be in the research? (c) How do we conduct the research? and (d) How do we move from research to practice? Across themes, symposium attendees emphasized the need for CAS research to better account for the diversity of people with CAS and improve the timeliness of implementation of high-level evidence-based practice across the lifespan. It is our goal that the articles and prologue discussion in this special issue provide an appreciation of advancements in CAS research and an updated view of the most pressing needs for future research.

Purpose: Health care is advancing toward a collaborative and integrative approach that promotes general health and wellness while addressing health inequities through the consideration of broader social and economic factors that influence the well-being of the entire population. Recently, there has been growing evidence of public health concept applications in fields related to speech, language, and hearing. However, there is an outstanding need to explicitly define the intersection of public health, including prevention and health promotion, and the discipline of communication sciences and disorders (CSD) across the areas of education, clinical practice, research, and policy. The authors propose a definition for this intersection using the new term communication public health. Method: This tutorial provides guidance on how to conceptualize communication public health and invites refinement and expansion of the intersection between public health and CSD. Because readers are experts in CSD, this tutorial aims to supplement existing knowledge with information on public health to achieve three main objectives: (a) increase knowledge of the application of public health concepts among speech, language, hearing, and related professionals (SLHP+); (b) introduce the concept of communication public health; and (c) discuss the relevance of communication public health across domains within CSD. The authors utilize the socioecological model to provide examples of applications. Results: The concept of communication public health is proposed as the collaborative area of CSD and public health, which encompasses prevention and promotion of equity in communication health through individual-, community-, and population-level efforts. The goals of communication public health are achieved through applications of public health principles in CSD education, clinical practice, research, and policy. Conclusion: Communication public health defines an area of collaboration between public health and CSD in which SLHP+ can apply public health concepts to both advance communication health and address health disparities.

Ecological momentary assessment (EMA) is a way to evaluate experiences in everyday life. It is a powerful research tool but can be complex and challenging for beginners. Application of EMA in audiological research brings with it opportunities and challenges that differ from other research disciplines. This tutorial discusses important considerations when conducting EMA studies in hearing care. While more research is needed to develop specific guidelines for the various potential applications of EMA in hearing research, we hope this article can alert hearing researchers new to EMA to pitfalls when using EMA and help strengthen their study design. The current article elaborates study design details, such as choice of participants, representativeness of the study period for participants' lives, and balancing participant burden with data requirements. Mobile devices and sensors to collect objective data on the acoustic situation are reviewed alongside different possibilities for EMA setups ranging from online questionnaires paired with a timer to proprietary apps that also have access to parameters of a hearing device. In addition to considerations for survey design, a list of questionnaire items from previous studies is provided. For each item, an example and a list of references are given. EMA typically provides data sets that are rich but also challenging in that they are noisy, and there is often unequal amount of data between participants. After recommendations on how to check the data for compliance, reactivity, and careless responses, methods for statistical analysis on the individual level and on the group level are discussed including special methods for direct comparison of hearing device programs.

Background: The role of participatory health research (PHR) is increasingly acknowledged by funding bodies, researchers and civil society globally; however, it continues to be under‐represented in the speech and language therapy (SLT) research literature. This collaborative research approach is associated with the increased application of research evidence, and the generation of positive impacts in practice, policy, health systems and society. Aims: To increase researchers' and other participatory partners' understanding of PHR, and to demonstrate its applicability to research in the SLT field. Methods & Procedures: This aim is achieved through a discussion on PHR, its principles, benefits and challenges, and the evaluation of its impact. A recently developed evaluation framework to support the implementation of best engagement practices is examined, and recommendations for how this framework can be used to plan and evaluate engagement in participatory stuttering research is presented. Main contribution: This paper serves as an important conversation on the value of PHR to SLT research, and presents guidance to support its increased implementation in this research field. Conclusions & Implications: Conclusions & Implications: PHR remains an under‐represented research approach in the SLT literature, despite increasing evidence demonstrating its effectiveness and value. It offers a potential solution to the research–practice gap, and challenges the ongoing research hierarchies by democrating the process of knowledge production. WHAT THIS PAPER ADDS: What is already known on this subject: PHR is increasingly attracting the attention of funders, researchers and decision‐makers due to a growing body of evidence in support of this collaborative research approach. Despite its potential to bridge the research–practice gap, PHR remains significantly under‐represented in the SLT research literature. What this paper adds to the existing knowledge: This paper discusses the principles, benefits, challenges and impact evaluation of PHR. A recently developed evaluation framework for supporting the implementation of best engagement practices is examined. A demonstration of how this framework can be used to plan and evaluate engagement in participatory stuttering research is presented. What are the potential or actual clinical implications of this work?: Speech and language therapists play a key role in PHR, as co‐researchers contributing essential context‐based knowledge. It is therefore imperative that they understand the principles and practices of this approach in order to maximize their input in future participatory partnerships. [ABSTRACT FROM AUTHOR]

Patient and public involvement (PPI) in research improves relevance to end users and improves processes including recruitment participants. PPI in our research has gone from being non-existent to ubiquitous over a few years. We provide critical reflections on the benefits and challenges of PPI. Case studies are reported according to a modified GRIP2 framework; the aims, methodology, impact of PPI and critical reflections on each case and our experiences with PPI in general. We report five UK projects that included PPI from teenagers, families, people living with dementia, autistic people, and people from South Asian and d/Deaf communities. Our experience has progressed from understanding the rationale to grappling methodologies and integrating PPI in our research. PPI took place at all stages of research, although commonly involved input to design including recruitment and development of study materials. Methodologies varied between projects, including PPI co-investigators, advisory panels and online surveys. On-going challenges include addressing social exclusion from research for people that lack digital access following increasing on-line PPI and involvement from underserved communities. PPI was initially motivated by funders; however the benefits have driven widespread PPI, ensuring our research is relevant to people living with hearing loss. [ABSTRACT FROM AUTHOR]

The current study examines the morphological knowledge (MK) and self-reported MK self-efficacy of speech-language pathologists (SLPs) and educators in an effort to inform professional development and preservice training related to MK and skills in implementing morphological instruction. This sample of 850 U.S. participants consisted of SLPs (n = 406), English language arts teachers (n = 178), special education teachers (n = 201), and reading specialists (n = 65). A survey elicited professional experience, self-efficacy related to the application of MK, and a MK measure. Correlations and analyses of variance (ANOVAs) between the groups that differed by disciplinary backgrounds were conducted to assess differences in MK and MK self-efficacy. The results yielded two key findings: (a) MK differs by profession, with SLPs performing with higher accuracy in morpheme counting and nonword derivation tasks and (b) MK self-efficacy differs by profession with reading specialists rating themselves significantly more confident than all other professions.

Introduction: Repetition priming can lead to improved naming ability in people with aphasia, but concerns have arisen from prior research about using only a single picture exemplar for each target. Specifically, it is unclear whether the observed improvements were due to learning simple correspondences between particular words and pictures rather than changes at a deeper level of lexical– semantic processing. In addition, implications for generalization after training with single exemplars were unclear. This study replicated and extended previous work to address these questions. Method: Five participants with chronic aphasia participated in this repeatedmeasures design study, which repeatedly paired words and pictures with no feedback provided. Two participants engaged in a single-exemplar condition, with a single picture exemplar of each target used for every presentation of that target. The remaining three participants engaged in a multiple-exemplar condition, with several different pictures used for each target. Half of these targets used training pictures during naming probes, whereas half did not. Results: Primed items led to greater improvements in naming than items that were practiced but not primed. The data indicate that improvements may extend beyond stimulus-specific correspondences. Maintenance and generalization effects were mixed. Conclusions: These data provide further support for the efficacy of repetition priming treatment for anomia. Implications and future directions are discussed. [ABSTRACT FROM AUTHOR]

Electropalatography (EPG) has been used in the past 50 years for studying the patterns of contact between the tongue and the palate during speech production in typical speakers and those with speech disorders due to different causes. At the 7th EPG Symposium in Japan that was held online on 24 January 2021 (see: ), a panel of invited experts discussed their views regarding further developments and application of the technique. This paper provides a summary of this discussion. EPG offers information on articulation which cannot be replaced by other instrumental measures of speech. Identified areas for further hardware development are thinner EPG plates, better dental and palatal coverage, wireless connectivity, and sensors that provide additional articulatory information (e.g. tongue pressure, tongue-palate distance). EPG can serve as a resource for teaching speech disorders and phonetics. Furthermore, EPG therapy can be combined with telepractice in the speech therapy of clients with speech disorders.

There is a consensus in psycholinguistic research that listening to unfamiliar speech constitutes a challenging listening situation. In this commentary, we explore the problems with the construct of non-native and ask whether using this construct in research is useful, specifically to shift the communicative burden from the language learner to the perceiver, who often occupies a position of power. We examine what factors affect perception of non-native talkers. We frame this question by addressing the observation that not all "difficult" listening conditions provide equal challenges. Given this, we ask how cognitive and social factors impact perception of unfamiliar accents and ask what our psycholinguistic measurements are capturing. We close by making recommendations for future work. We propose that the issue is less with the terminology of native versus non-native , but rather how our unexamined biases affect the methodological assumptions that we make. We propose that we can use the existing dichotomy to create research programs that focus on teaching perceivers to better understand talkers more generally. Finally, we call on perceivers and researchers alike to question the idea of speech being "native," "non-native," "unfamiliar," and "accented" to better align with reality as opposed to our inherently biased views.

Purpose: The ongoing replication crisis within and beyond psychology has revealed the numerous ways in which flexibility in the research process can affect study outcomes. In speech research, examples of these “researcher degrees of freedom” include the particular syllables, words, or sentences presented; the talkers who produce the stimuli and the instructions given to them; the population tested; whether and how stimuli are matched on amplitude; the type of masking noise used and its presentation level; and many others. In this research note, we argue that even seemingly minor methodological choices have the potential to affect study outcomes. To that end, we present a reanalysis of six existing data sets on spoken word identification in noise to assess how differences in talkers, stimulus processing, masking type, and listeners affect identification accuracy. Conclusions: Our reanalysis revealed relatively low correlations among word identification rates across studies. The data suggest that some of the seemingly innocuous methodological details that differ across studies—details that cannot possibly be reported in text given the idiosyncrasies inherent to speech— introduce unknown variability that may affect replicability of our findings. We therefore argue that publicly sharing stimuli is a crucial step toward improved replicability in speech research. [ABSTRACT FROM AUTHOR]

Purpose: In the last decade, psychology and other sciences have implemented numerous reforms to improve the robustness of our research, many of which are based on increasing transparency throughout the research process. Among these reforms is the practice of preregistration, in which researchers create a timestamped and uneditable document before data collection that describes the methods of the study, how the data will be analyzed, the sample size, and many other decisions. The current article highlights the benefits of preregistration with a focus on the specific issues that speech, language, and hearing researchers are likely to encounter, and additionally provides a tutorial for writing preregistrations. Conclusions: Although rates of preregistration have increased dramatically in recent years, the practice is still relatively uncommon in research on speech, language, and hearing. Low rates of adoption may be driven by a lack of understanding of the benefits of preregistration (either generally or for our discipline in particular) or uncertainty about how to proceed if it becomes necessary to deviate from the preregistered plan. Alternatively, researchers may see the benefits of preregistration but not know where to start, and gathering this information from a wide variety of sources is arduous and time consuming. This tutorial addresses each of these potential roadblocks to preregistration and equips readers with tools to facilitate writing preregistrations for research on speech, language, and hearing.

When engaging in research with marginalized communities, it is important for researchers to reflect on their practice and consider what steps they can take to avoid perpetuating inequality or causing harm. This article provides guidance for researchers working with trans and gender-diverse individuals from the perspective of two speech-language pathologists. Key considerations presented by the authors include the importance of engaging in reflexive research practices—thinking deeply about and acknowledging impacts of one's personal beliefs, values, and practices on one's research—and developing an awareness of factors that contribute to the trans and gender-diverse community's ongoing minority stress. Specific suggestions to redress power imbalance between the researcher and the researched community are provided. Finally, practical methods for implementing the guidance are presented: the community-based participatory research model and an example in speech-language pathology research with trans and gender-diverse individuals.

Recent work has demonstrated that high-frequency (>6 kHz) and extended high-frequency (EHF; >8 kHz) hearing is valuable for speech-in-noise recognition. Several studies also indicate that EHF pure-tone thresholds predict speech-in-noise performance. These findings contradict the broadly accepted "speech bandwidth" that has historically been limited to below 8 kHz. This growing body of work is a tribute to the work of Pat Stelmachowicz, whose research was instrumental in revealing the limitations of the prior speech bandwidth work, particularly for female talkers and child listeners. Here, we provide a historical review that demonstrates how the work of Stelmachowicz and her colleagues paved the way for subsequent research to measure effects of extended bandwidths and EHF hearing. We also present a reanalysis of previous data collected in our lab, the results of which suggest that 16-kHz pure-tone thresholds are consistent predictors of speech-in-noise performance, regardless of whether EHF cues are present in the speech signal. Based on the work of Stelmachowicz, her colleagues, and those who have come afterward, we argue that it is time to retire the notion of a limited speech bandwidth for speech perception for both children and adults.

Intensive Comprehensive Aphasia Programs (ICAPs) were first described in 2013 with an international survey documenting 12 unique programs. ICAPs involve high dose intervention delivered in both group and individual settings, targeting communication across impairment, functioning, participation, and contextual domains. In this study, we aimed to investigate international growth in ICAPs. We developed a 43-item questionnaire expanding on the original 2013 version to investigate program modifications, activities, protocolised therapies, software and apps, and family involvement. The survey was disseminated to aphasia clinicians and researchers internationally (November 2019–February 2020). Thirty-nine unique respondents completed the survey from nine countries. Twenty-one met the criteria for an ICAP or modified ICAP (mICAP): 14 ICAPs; 7 mICAPs, and 13 of these were new programs. ICAPs differed from mICAPs with greater emphasis on group sessions, use of technology, total communication, advocacy, and art activities. A large range of protocolised therapies were used across programs. An increased focus on mood and psychosocial well-being was observed compared to the 2013 survey. The number and comprehensiveness of ICAPs has grown since 2013 with development of modified versions. Future research should focus on comparative efficacy of ICAPs/mICAPs and other forms of aphasia interventions and factors underpinning growth and sustainability. Clinicians who coordinate or are considering commencing an ICAP in future can use these results to consider the design of their program. Coordinators should carefully consider the components of their ICAPs and advise consumers whether they meet the definition of an ICAP or a mICAP. With the increasing number of ICAPs across the globe, clinicians commencing an ICAP may wish to contact existing ICAPs within their country for advice. Program sustainability may be challenging and these results provide an indication of some of the key challenges coordinators may face. [ABSTRACT FROM AUTHOR]

The auditory brainstem response (ABR) and middle latency response (MLR) are two sets of evoked potentials that have made major contributions to the field of diagnostic audiology. Many of these contributions were guided by clinical research audiologists. Though many of these auditory evoked potentials (AEPs) are still being used diagnostically by audiologists, there has been a steep decline in their popularity both clinically and in the research laboratory. This is indeed most unfortunate because these AEPs could and should be advancing our field and benefitting many patients. In this article, some critical research is overviewed that addresses some of the reasons why these AEPs (ABR and MLR) are not being utilized as frequently as they should be for neuroauditory assessments. Reflecting on our past when ABR and MLR were more commonly used can serve as a model for our future. Multiple applications and the diagnostic value of these AEPs are presented in an effort to convince audiologists that these electrophysiologic procedures should be revisited and reapplied in the clinic and research settings. It is argued that the dwindling use of ABR and MLR (and AEPs in general) in the field of audiology is not only remarkably premature but also lacks good scientific grounding. While on the other hand, if applied clinically, the value of these AEPs is both substantial and promising. [ABSTRACT FROM AUTHOR]

Purpose: The external validity of aphasia treatment research relies on diverse and representative participants. The purposes of this study were (a) to examine whether reporting of patient-reported age, sex, and race/ethnicity has improved since Ellis (2009) and (b) to evaluate whether these demographic variables were consistent with population-level estimates of stroke survivor demographics in the United States. Method: A scoping review examined U.S.-based aphasia treatment studies published between 2009 and 2019 and characterized the percentage of studies reporting age, sex, and race/ethnicity. Summary statistics for these variables were calculated and compared statistically with a population-based study of stroke survivors. Results: It was found out that 97.1% of studies reported age, 93.5% reported sex, and 28.1% reported race and/or ethnicity. Within reporting studies, participant mean age was 58.04 years, 61.6% of participants were men, and 38.4% were women; 86.5% of participants were White, 11.0% were Black, 2.0% were Hispanic/Latino, and 0.5% fell in other racial categories. All three variables were statistically different from the study of Kissela et al. (2012). Discussion: Despite being highlighted as an issue by Ellis (2009), less than 30% of recent aphasia treatment studies reported race or ethnicity, and participants do not appear to be demographically representative compared with estimates of stroke survivors living in the United States. These issues may negatively impact the ecological validity of aphasia treatment research. Aphasia researchers should more consistently report participant race and ethnicity and follow current guidelines for increasing the demographic representation of women and minorities.

Purpose: To describe the 9-year journey of a group of language and literacy researchers in establishing and cultivating Research-Practice Partnerships (RPPs). Those interested in incorporating implementation science frameworks in their research may benefit from reading our exploration into this type of work and our lessons learned. Method: We showcase how a group of researchers, who are committed to collaboration with school practitioners, navigated building and scaling RPPs within educational systems necessary for our long-term implementation work. We provide details and illustrative examples for three, distinct, mutually beneficial, and sustainable partnerships. Results: Three different practice organizations are represented: (1) a single metropolitan school, (2) a small metropolitan school district, and (3) a large metropolitan school district, highlighting specific priorities and needs depending on the type of practice organization. Each partnership has distinct research and practice goals related to improving language and literacy outcomes in children. We describe how the researchers assisted with meeting the partner practice organizations' goals and engaged in capacity building while producing rigorous scientific knowledge to inform clinical and educational practice. Additionally, we discuss how research priorities and strategies were pivoted in the past year due to the COVID-19 pandemic, illustrating our commitment to the partnerships and how to respond to challenges to guarantee long-term sustainability. Conclusion: By discussing three distinctive partnerships, we demonstrate the various ways researchers can approach RPPs and grow them into mutually beneficial collaborations and support implementation goals.

Coordination of international aphasia research would minimise duplication of effort, support synergistic international activities across languages and multidisciplinary perspectives, and promote high-quality conduct and reporting of aphasia research, thereby increasing the relevance, transparency, and implementation of findings. The Collaboration of Aphasia Trialists (CATs) sought to develop an aphasia research agenda to direct future research activities, based on priorities shared by people with aphasia, family members, and healthcare professionals. Our established international research network spanning 33 countries contributed to this activity. Research literature reporting the priorities of stakeholders was reviewed and synthesized (phase 1). Representatives from Working Groups on Aphasia Assessment & Outcomes, Prognosis & Predictors of Recovery, Effectiveness of Interventions, and Societal Impact & Reintegration participated in a two-day research agenda-setting meeting. The CATs expert panel refined research objectives and identified constituent components of research and methodological developments required to address these research components. The objectives and research components were grouped into overarching themes (phase 2). The resultant list was then circulated to more than 180 CATs members for review, revision, and approval. Consensus on the final aphasia research agenda and roadmap was reached by CATs executive committee (phase 3). The expert panel identified five overarching research themes: (i) evidence-based interventions for people with aphasia, (ii) effective interventions to support those communicating with people with aphasia, (iii) cross-linguistic assessment and core outcomes for aphasia research, (iv) predictors of language recovery, and (v) clinical implementation of research findings. Within these broad themes, 30 research objectives and 91 individual aphasia research components were identified and sequentially ordered. This agenda builds on research priorities identified by people with aphasia and their families, and includes priorities of healthcare professionals and researchers, and will support the rehabilitation and recovery of people with aphasia. Our internationally relevant research agenda promotes rigor in methodology, considers international applicability, synergistic activities, and sharing of resources and expertise.

Background: Person‐centred care (PCC) has shown positive effects in various health‐care settings and therefore is desirable in clinical work. However, as PCC is still being developed, the literature reflects a heterogeneous use of both terminology and conceptualisation. This lack of consistency hinders the implementation or adaptation of PCC in general and in select fields of practice such as speech‐language therapy (SLT). Aims: To describe how the concept of PCC manifests in current speech and language therapy research and practice for adult patients. Methods & Procedures: Searches for published literature were conducted in five databases (PubMed, Scopus, CINAHL, Psych INFO, and Linguistics and Language Behaviour Abstracts) using search terms related to PCC and SLT. Records were included if they involved an adult population, were written in English, and focused on PCC and SLT irrespective of year of publication. Main Contribution: A total of 134 records published 1996–2020 were included in this review. Many of these records were discussion papers that described how speech‐language therapists (SLTs) can or should work in a person‐centred way. The search did not find any records that explore the implementation, effects, or patients' views of person‐centred SLT. This literature review revealed that person‐centred SLT practice mainly relates to the International Classification of Functioning, Disability, and Health framework, and the Life Participation Approach to Aphasia. Studies incorporating exploration of proposed clinical routines of PCC demonstrate specific context‐dependant aspects including barriers to eliciting a patient narrative, involving patient and family members, and documenting SLT. Conclusions & Implications: This study provides information that can be used to implement person‐centred care in SLT education, clinical practice, and research by providing an inventory of the current knowledge and the existing gaps. What is already known on the subject: PCC has shown positive effects and is currently being implemented in various health‐care settings worldwide. What this paper adds to existing knowledge: This study provides an account of the current state in research and practice on how PCC for adults is described, discussed, and evaluated. While related concepts such as family‐centred care have mainly been explored within paediatrics, little is known about how PCC manifests in SLT for adults. Our results show that PCC is presently being discussed and valued in SLT although obstacles exist, and few studies explore whether current practice is person centred and the potential effects of such practice. What are the potential or actual clinical implications of this work?: This study provides clinicians, researchers, and policymakers' guidance on what aspects to consider when working to implement person‐centred SLT for adults.

The article discusses the importance of stakeholder-engaged research (SER) in producing meaningful and useful research products, particularly for individuals with communication disabilities.

Purpose: The purposes of this meta-review are to (a) articulate the importance of transparency and reproducibility in meta-analysis, (b) assess the transparency and reproducibility of meta-analyses published in journals of the American Speech-Language-Hearing Association (ASHA), and (c) discuss the implications of our findings and recommendations for future research. Method: We conducted a meta-review of all meta-analyses published in ASHA journals through December 31, 2020. Our systematic review yielded 47 meta-analyses for inclusion in this review. We coded all eligible reports on the core elements of transparency and reproducibility in meta-analysis. Results: Our findings suggest that though reporting tendencies have improved over time, much work is needed to promote transparency and reproducibility in meta-analytic work. Key areas for future accountability include preregistering study protocol, using Preferred Reporting in Systematic Reviews and Meta-Analysis checklists, providing full data sets, and publishing analytic codes. Conclusions: The state of reporting in meta-analysis is improving over time. We conclude with a discussion of specific areas that need further attention, and recommendations for researchers to consider when conducting future meta-analyses.

Purpose: The use of technology (e.g., telehealth) in clinical settings has rapidly increased, and its use in research settings continues to grow. The aim of this report is to present one potential solution to a clinical issue that of virtual and remote assessment for the purposes of spoken language research in persons with aphasia (PWA). To do so, we report detailed methods for conducting a multitimepoint (test–retest) virtual paradigm, assessing lifestyle, physiological, cognitive, and linguistic factors in persons with and without aphasia. Method: Procedures for virtual assessment are detailed in a sample of adults with no brain damage (N = 24) and PWA (N = 25) on a test–retest paradigm (data collection approximately 10 ± 3 days apart). This report provides practical information about pre-assessment (e.g., recruitment, scheduling), assessment (e.g., aphasia-friendly consent presentation, investigator fidelity), and postassessment (e.g., data storage, quality check) procedures for human behavior research using a virtual platform. Results: Preliminary study data are provided, indicating high retention rates, high rates of data acquisition, and feasibility. Common technological troubles and solutions are discussed, and solutions are offered. The results suggest that our pre-assessment, assessment, and postassessment procedures contributed to the success of our study. Conclusions: We provide a practical methodology for conducting a multitimepoint study, with considerations for PWA, adding to the body of research on telehealth in clinical populations. Future studies should continue to evaluate telemethodology, which may be core for diversifying studies, improving study retention, and enrolling larger sample sizes. [ABSTRACT FROM AUTHOR]

The author discusses two letters that appear in the journal concerning the positive reinforcement and respect for the human rights and personal dignity of autistic people in intervention research and communicative disorders research. He states that the rights of what he calls neurodiverse people are the most important aspects of the development and testing of social skills and communication skills.

Background and aims: Clinician engagement in research has the potential to improve healthcare processes and facilitate evidence-based practice. As a means to encourage clinician research engagement and links between speech-language pathology (SLP) clinicians in practice and researchers in higher education institutions, a national SLP clinician-academic research community of practice was established. The first steps for this newly formed research community was to determine stakeholder aims, to prioritize those aims and specify actions which would help respond to the stated priorities. Methods: The study was conducted in Ireland and the Irish Association of Speech and Language Therapists acted as a gatekeeper who forwarded a study information sheet and expression of interest form to its membership. A World Cafe´ methodology was utilized to gather data and conducted as part of the inaugural meeting where consent was retrieved. As part of this methodology, the participants created and managed their own data with the help of group facilitators. Results: Thirty six members replied expressing interest and 15 participants attended the inaugural meeting. Participants represented both clinical and research communities and identified and prioritized aims for the research community of practice. The aims were, in order of prioritization: Dissemination, Education, Enablers, Networking and Advocacy. Participants agreed that what they labelled as Dissemination was the number one priority for the newly formed research community of practice. In this context Dissemination referred to the identification of research already being conducted by participants and the sharing of that research both within the group and the larger SLP community nationally and internationally. Various actions were proposed to achieve agreed aims and these reflected a variety of targeted (e.g. development of a research database) and generic (e.g. to act as advocates) activities as well as local and national strategies including lobbying for clinical-research posts. Conclusion: Clear aims, priorities and actions were identified by SLP clinical and research participants to facilitate the development of a research community of practice. This article presents the results of that exercise and outlines the priorities of participants who identified five aims in total. Dissemination was the number one priority for the newly formed research group and manifested a desire to share information about participants' research activities. The prioritized aims reflect assured thinking and form a solid co-constructed footing for the research community to develop and grow. [ABSTRACT FROM AUTHOR]

Purpose: This article provides an overview of five papers appearing together on the topic of "Advances in Specific Language Impairment Research and Intervention," which was the 2019 program in an ongoing series of research symposia presented at the Annual Convention of the American Speech-Language-Hearing Association. Method: The article provides a historical context for the set of papers, then a short summation of each paper's content, followed by the identification of overarching themes and working conclusions. Results: Each paper provides summations of empirical results, and some papers provide new empirical evidence. Conclusion: The papers collectively highlight six points: (a) Children with specific language impairment (SLI) are likely to be unidentified among their age peers. (b) There is great need for better identification of children with SLI across developmental levels. (c) Progress is evident toward a better understanding of causal pathways, as examined across different research designs involving comparison of children with typical language acquisition to children with SLI and other possibly co-occurring atypical conditions. (d) Measuring multiple dimensions of language brings enhanced informativeness, with differing outcomes for differing dimensions. (e) Replicated research findings require precision of methods in order to reduce unexplained error variance especially when defining groups. (f) Accurate identification of children with SLI is the first step toward a sound treatment plan for SLI and reading disorders as well. [ABSTRACT FROM AUTHOR]

Purpose: Despite the American Speech-Language-Hearing Association's (ASHA's) endorsement of evidence-based practice (EBP) and speech-language pathologists' (SLPs') agreement on the importance of EBP, practicing clinicians report barriers to implementing EBP. The purpose of this study was to examine trends in clinical practice research published in ASHA journals over the past 11 years (2008- 2018). Method: A total of 2,483 articles from the American Journal of Speech-Language Pathology; Language, Speech, and Hearing Services in Schools; and Journal of Speech, Language, and Hearing Research were extracted for coding. Coders were licensed SLPs who were trained to 80% reliability on classifying the type of research in each article. Clinical practice research articles were further classified as studies on assessment, studies on intervention, and studies that explore the implementation of EBP. Results: Clinical practice research comprised the minority of literature published in ASHA journals in the field of speech-language pathology (25%). These articles were composed of assessment (10%), intervention (15%), and implementation (< 1%). These articles were distributed across a variety of primary content areas, with an absence of implementation science for the majority of clinical areas. Conclusions: The lack of clinical practice research readily available to practicing SLPs is a barrier to EBP. The results of this study underscore the need for increased clinical practice research. Future work should investigate EBP in the context of clinician-researcher partnerships and increasing the capacity of clinicians to conduct clinical practice research. [ABSTRACT FROM AUTHOR]

Background: Collaboration between parents and speech and language therapists (SLTs) is seen as a key element in family‐centred models. Collaboration can have positive impacts on parental and children's outcomes. However, collaborative practice has not been well described and researched in speech and language therapy for children and may not be easy to achieve. It is important that we gain a deeper understanding of collaborative practice with parents, how it can be achieved and how it can impact on outcomes. This understanding could support practitioners in daily practice with regard to achieving collaborative practice with parents in different contexts. Aims: To set a research agenda on collaborative practice between parents and SLTs in order to generate evidence regarding what works, how, for whom, in what circumstances and to what extent. Methods & Procedures: A realist evaluation approach was used to make explicit what collaborative practice with parents entails. The steps suggested by the RAMESES II project were used to draft a preliminary programme theory about collaborative practice between parents and SLTs. This process generates explicit hypotheses which form a potential research agenda. Discussion & Conclusions: A preliminary programme theory of collaborative practice with parents was drafted using a realist approach. Potential contextual factors (C), mechanisms (M) and outcomes (O) were presented which could be configured into causal mechanisms to help explain what works for whom in what circumstances. CMO configurations were drafted, based on the relevant literature, which serve as exemplars to illustrate how this methodology could be used. In order to debate, test and expand our hypothesized programme theory for collaborative practice with parents, further testing against a broader literature is required alongside research to explore the functionality of the configurations across contexts. This paper highlights the importance of further research on collaborative practice with parents and the potential value of realist evaluation methodology. What this paper addsCurrent policy in education, health and social care advocates for family‐centred care and collaborative practice with parents. Thereby, collaborative practice is the preferred practice for SLTs and parents. In this paper, we explore collaborative practice and use a realist evaluation approach to achieve the aim of setting a research agenda in this area. Researchers use realist evaluation, a methodology originally developed by Pawson and Tilley in the 1990s, to explore the causal link between interventions and outcomes, summarized as what works, how, for whom, in what circumstances and to what extent. Realist evaluation provides a framework to explore configurations between contexts (C), mechanisms (M) and outcomes (O). We used this methodology to take a first step at making explicit what collaborative practice is and how it might be achieved in different contexts. We did this by drafting a preliminary programme theory about collaborative practice, where we made explicit what context factors and mechanisms might influence outcomes in collaborative practice between parents and SLTs. Based on this programme theory, we argue for the need to develop a research agenda on collaborative practice with parents of children with speech, language and communication needs. The steps between a programme theory and a research agenda could entail exploring each CMO, or step in the programme theory, and evaluating it against the existing literature—both within and beyond speech and language therapy—to see how far it stands up. In this way, gaps could be identified that could be converted into research questions that would stimulate debate about a research agenda on collaborative practice. Understanding how collaborative practice can be achieved in different contexts could support SLTs to use mechanisms to optimise collaborative practice intentionally and tailor interventions to the specific needs of families, thereby enhancing collaborative practice between parents and SLTs.

Purpose: The purpose was to examine and determine effect size distributions reported in published audiology and speech-language pathology research in order to provide researchers and clinicians with more relevant guidelines for the interpretation of potentially clinically meaningful findings. Method: Cohen's d, Hedges' g, Pearson r, and sample sizes (n = 1,387) were extracted from 32 meta-analyses in journals in speech-language pathology and audiology. Percentile ranks (25th, 50th, 75th) were calculated to determine estimates for small, medium, and large effect sizes, respectively. The median sample size was also used to explore statistical power for small, medium, and large effect sizes. Results: For individual differences research, effect sizes of Pearson r = .24, .41, and .64 were found. For group differences, Cohen's d/Hedges' g = 0.25, 0.55, and 0.93. These values can be interpreted as small, medium, and large effect sizes in speech-language pathology and audiology. The majority of published research was inadequately powered to detect a medium effect size. Conclusions: Effect size interpretations from published research in audiology and speech-language pathology were found to be underestimated based on Cohen's (1988, 1992) guidelines. Researchers in the field should consider using Pearson r = .25, .40, and .65 and Cohen's d/Hedges' g = 0.25, 0.55, and 0.95 as small, medium, and large effect sizes, respectively, and collect larger sample sizes to ensure that both significant and nonsignificant findings are robust and replicable.

Background: Technology devices and applications including virtual reality (VR) are increasingly used in healthcare research and practice as tools to promote health and wellbeing. However, there is limited research examining the potential for VR to enable improved communication for people with communication disability. Aims: To review: (a) current research using VR in speech-language pathology; and (b) the ethical and safety considerations of VR research, to inform an agenda for future research applying VR in the field of speech-language pathology. Main contribution: This review reveals that there is an emergent body of literature applying VR to improve or develop physical, psychological and communication interventions. Use of non-immersive virtual environments to provide speech-language pathology assessment or intervention for people with communication disability has demonstrated positive outcomes, with emerging evidence of the transfer of functional communication skills from virtual to real-world environments. However, the use of VR technology and immersive virtual environments in communication disability practice and research introduces safety and ethical issues that must be carefully considered. Conclusions: Research employing VR is in its infancy in the field of speech-language pathology. Early evidence from other healthcare disciplines suggests that VR is an engaging means of delivering immersive and interactive training to build functional skills that can be generalized to the real world. While the introduction of new technology requires careful consideration of research ethics and patient safety, future VR communication research could proceed safely with adequate engagement of interdisciplinary teams and technology specialists. Immersive virtual reality may be used in rehabilitation to simulate natural environments to practice and develop communication skills. The sense of immersion that can be achieved using virtual reality may promote the generalization of skills learnt during clinical rehabilitation to real-world situations. Ethical and safety considerations, including cybersecurity and cybersickness, must be carefully monitored during all virtual reality research. [ABSTRACT FROM AUTHOR]

Purpose: Evidence-based data analysis methods are important in clinical research fields, including speechlanguage pathology and audiology. Although commonly used, null hypothesis significance testing (NHST) has several limitations with regard to the conclusions that can be drawn from results, particularly nonsignificant findings. Bayes factors (BFs) can be used to complement NHST and quantify the strength of evidence in favor of 1 hypothesis over another, given the data: commonly, either the alternate hypothesis over the null or the null hypothesis over the alternate. This article provides an introduction to BFs through JASP, a free, open-source, graphics-based statistics package that allows researchers to easily conduct both NHST and Bayesian analyses in a clear and reproducible manner. Method and Results: Both traditional NHST analyses and Bayesian equivalents for correlations, t tests, and analyses of variance were conducted in JASP using simulated data, with explanations of analysis options, statistical output, and figures provided. These examples also demonstrate what NHST and BFs can and cannot infer about a data set. Additionally, BFs were calculated from the summary statistics of published nonsignificant results to illustrate how JASP may be useful to consumers of research who only have access to statistics provided in a published study. Conclusions: Bayesian analyses are underutilized in speech, language, and hearing research. By complementing traditional NHST analyses with BFs, researchers can directly test for and quantify the strength of evidence during hypothesis testing, thereby drawing stronger conclusions from their research and providing more relevant information for clinicians and researchers in the field.

A list of dissertations about deafness in 2019 is presented, including "Politics and Media Among the Deaf and Hard of Hearing" by C. Deering, "Speech Production of Children With Hearing Loss" by M. Taylor, and "Deaf Latino Students: A Grounded Theory of Educators' Narratives" by M. J. Hom.

Purpose: This article is concerned with the growing body of international evidence indicating that adolescents in contact with the youth justice system are likely to have severely compromised oral language skills, receptively and expressively. A smaller, but persuasive, literature also points to poor literacy skills in this population. Language and literacy skills underpin academic, social, and vocational success (C. Snow, 1983; P. C. Snow, 2016; Snowling & Hulme, 2012) and are central to the professional expertise of speechlanguage pathology as a profession (P. C. Snow, 2016). Method: In this article, I review the epidemiology of youth offending together with research evidence concerning the language and literacy skills of this population. I outline the major practice and research implications of these findings for speech-language pathology as a profession, considering the "school-to-prison pipeline" via key domains of early years' reading instruction, young people's passage through the justice system, restorative justice processes, and design and delivery of language and literacy interventions for young people on youth justice orders. Results: Implications for speech-language pathology scope of practice and future research are outlined. Conclusions: Speech-language pathology as a profession has a significant role to play in advocating for vulnerable young people at each point in the school-to-prison pipeline. This includes strengthening the evidence base concerning speechlanguage pathology language and literacy interventions and lobbying governments to fund speech-language pathology services to address the complex communication needs of this population, both on community-based and custodial orders.

Purpose: Measuring change is a common goal in clinical research, and comparing nonequivalent groups is sometimes a necessity in this context. Yet, evaluating change in this way can be problematic, and little consensus is reported on the best way to conduct such an evaluation. This tutorial presents the process of planning a clinical study designed to measure change in the context of a therapeutic intervention. Method: This article presents a hypothetical clinical research scenario and follows the process of study design from question formulation to interpretation of results. The presentation focuses on the use of gain score analysis in the context of nonequivalent participant groups, methods that may be particularly relevant to the clinical context. Conditions that are favorable to gain score use, as well as situations that are problematic for gain score use, are presented. Conclusions: In this article, the clinical research process is presented, following a logical process from formulation of a clear research question to selection of an appropriate research design to implementation of an effective analysis method. Gain score analysis is presented as an effective tool to measure change in clinical research, even with nonequivalent groups, given the correct conditions. [ABSTRACT FROM AUTHOR]

Purpose: Research in communication sciences and disorders frequently involves the collection of clusters of observations, such as a series of scores for each individual receiving treatment over the course of an intervention study. However, little discipline-specific guidance is currently available on the subject of building and interpreting multilevel models. This article offers a tutorial on multilevel models, using notation from the R statistical software, and discusses their implications for research in communication sciences and disorders. Method: This tutorial introduces multilevel models and contrasts them with other methods to analyze repeated measures data, such as repeated measures analysis of variance or standard linear regression. It also provides guidance on interpreting the components of a multilevel model and selecting the best-fitting model. Finally, these models are illustrated through an analysis of real data from a study of speech production training in second-language speakers of English. Conclusions: As a flexible method that can increase the rigor of modeling for clustered data, multilevel modeling represents an important tool for research in communication disorders. Given their increasingly prominent role in the analysis of experimental data in communication sciences, it is important for researchers to be familiar with the basics of building and interpreting these models.

Purpose: Clinicians depend on the accuracy of research in the speech, language, and hearing sciences to improve assessment and treatment of patients with communication disorders. Although this work has contributed to great advances in clinical care, common statistical misconceptions remain, which deserve closer inspection in the field. Challenges in applying and interpreting traditional statistical methods with behavioral data from humans have led to difficulties with replication and reproducibility in other allied scientific fields, including psychology and medicine. The importance of research in our fields of study for advancing science and clinical care for our patients means that the choices of statistical methods can have far-reaching, real-world implications. Method: The goal of this article is to provide an overview of fundamental statistical concepts and methods that are used in the speech, language, and hearing sciences. Results: We reintroduce basic statistical terms such as the p value and effect size, as well as recommended procedures for model selection and multiple comparisons. Conclusions: Research in the speech, language, and hearing sciences can have a profound positive impact on the lives of individuals with communication disorders, but the validity of scientific findings in our fields is enhanced when data are analyzed using sound statistical methods. Misunderstanding or misinterpretation of basic statistical principles may erode public trust in research findings. Recommendations for practices that can help minimize the likelihood of errors in statistical inference are provided. [ABSTRACT FROM AUTHOR]

Patient-centered care is extending the sphere of health care beyond the patient, focusing attention upon the family caregiver(s). In this context, patient-family relationships are at the center of consistent, well-developed interprofessional interventions that encompass caregiver education, training, and wellness. Cohort models of intervention include groups of patients who start and stop a program or intervention simultaneously. One such cohort-based service delivery model is an intensive comprehensive aphasia program (ICAP), which provides an ideal context in which to address holistic care for the person with aphasia and his or her family caregivers. The interprofessional family caregiver intervention program of the ICAP at the University of Montana is twofold: (1) speech-language pathologists and graduate student clinicians in speech-language pathology provide family caregiver education and resources, communication training, and psychosocial support and (2) a licensed professional counselor and counselor-in-training provide group counseling for family caregivers focusing on personal wellness, caregiving strategies, emotional health, and adaptation to significant life changes. The fusion of equitable interprofessional collaboration, along with the cohort model of the ICAP, allows for acquisition of knowledge, communication strategies, and coping skills along with the development of close, meaningful relationships with other caregivers and persons with aphasia.

Augmentative and alternative communication (AAC) is always about intervening and the subsequent effects of the interventions (e.g., on the AAC user, family perspectives, educational outcomes, and vocational outcomes). AAC intervention research is about generating new knowledge by studying some aspect of AAC delivery in a planned manner so that it can be replicated and then translated into clinical/educational practice. This commentary on AAC intervention research highlights the complexities inherent in this type of research and the range of components that contribute to it, and reflects on emerging trends that we must consider as we continue to develop and enhance intervention research. Conducting AAC intervention research is a commitment to understanding how change occurs when an intervention is delivered and its broader impact on the field and the people who use AAC.

Abstract: Background: Communication partner training (CPT) has been used to support communication partners to interact successfully with people with aphasia (PWA). Through successful CPT interaction PWA's accessibility to healthcare is notably improved. The present study sought to build on prior studies by investigating the experiences of individuals with aphasia and healthcare providers to ascertain what they deemed to be beneficial from CPT and what could be refined or improved, dependent on the setting and skill set of those participating. Aims: To gain an understanding of the experiences of PWA involved in the provision of CPT to health professional (HP) students. Also to investigate the experiences of HP students who participated in the CPT programme. Methods & Procedures: Eight PWA and 77 HP students who had completed a CPT programme participated in a focus group/semi‐structured interview (PWA) and feedback session (HP students) moderated by two speech–language pathologists (SLPs). These sessions were recorded (audio and video), transcribed verbatim, including non‐verbal communication, and analyzed using qualitative content analysis. Outcomes & Results: Overall, the study sought to understand experiences of the training. Both the PWA and HP students reported positive experiences of CPT. PWA discussed their perception that CPT improved HPs and HP students’ understanding and interactions conversing with them and emphasized the need for training and education for all health related professions. HP students enjoyed the opportunity to experience interacting with PWA, without being ‘assessed’ and felt it consolidated their learning based on lecture content. Conclusions & Implications: Inclusive and accessible healthcare is paramount to ensure the engagement of patients and providers. Based on the experiences and feedback of the participants in this current study, CPT offers a salient and practical training method with potential to improve practice. Participants perceived CPT to be beneficial and validated the need for the training to support PWA accessing healthcare. [ABSTRACT FROM AUTHOR]

Purpose: Statistical learning--the ability to learn patterns in environmental input--is increasingly recognized as a foundational mechanism necessary for the successful acquisition of spoken language. Spoken language is a complex, serially presented signal that contains embedded statistical relations among linguistic units, such as phonemes, morphemes, and words, which represent the phonotactic and syntactic rules of language. In this review article, we first review recent work that demonstrates that, in typical language development, individuals who display better nonlinguistic statistical learning abilities also show better performance on different measures of language. We next review research findings that suggest that children who are deaf and use cochlear implants may have difficulties learning sequential input patterns, possibly due to auditory and/or linguistic deprivation early in development, and that the children who show better sequence learning abilities also display improved spoken language outcomes. Finally, we present recent findings suggesting that it may be possible to improve core statistical learning abilities with specialized training and interventions and that such improvements can potentially impact and facilitate the acquisition and processing of spoken language. Method: We conducted a literature search through various online databases including PsychINFO and PubMed, as well as including relevant review articles gleaned from the reference sections of other review articles used in this review. Search terms included various combinations of the following: sequential learning, sequence learning, statistical learning, sequence processing, procedural learning, procedural memory, implicit learning, language, computerized training, working memory training, statistical learning training, deaf, deafness, hearing impairment, hearing impaired, DHH, hard of hearing, cochlear implant(s), hearing aid(s), and auditory deprivation. To keep this review concise and clear, we limited inclusion to the foundational and most recent (2005-2018) relevant studies that explicitly included research or theoretical perspectives on statistical or sequential learning. We here summarize and synthesize the most recent and relevant literature to understanding and treating language delays in children using cochlear implants through the lens of statistical learning. Conclusions: We suggest that understanding how statistical learning contributes to spoken language development is important for understanding some of the difficulties that children who are deaf and use cochlear implants might face and argue that it may be beneficial to develop novel language interventions that focus specifically on improving core foundational statistical learning skills.

Purpose: The purpose of this article is to provide a tutorial on statistical learning and its role in learning to spell and to discuss the implications of the research for educators. Method: The tutorial begins with a discussion of statistical learning and its characteristics. It then discusses research on how statistical learning plays out in learning to spell, how spelling should be taught, and similarities and differences among learners. The focus is on the learning of English, although studies of other alphabetic writing systems are also considered. Research shows that, from an early age, children use their statistical learning skills to learn about the visual characteristics of written words. Children also use their statistical learning skills to help learn about the relations between visual units and units of language, supplementing what they are explicitly taught in school. Conclusion: Statistical learning plays an important role in learning to spell, and this can help to explain why some aspects of spelling are more difficult to learn than others. If children are to learn to spell effectively and efficiently, structured instruction is also important. [ABSTRACT FROM AUTHOR]

Purpose: Over the last 2 decades, research on statistical learning has demonstrated its importance in supporting language development. Notably, most of the research to date has focused on monolingual populations (or has not reported the language background of participants). Several recent studies, however, have begun to focus on the impact of bilingualism on statistical learning. To date, the results have been quite mixed, with a handful of studies finding differences between monolinguals and bilinguals and several other studies reporting no differences. Thus, the purpose of this manuscript is to review the literature to date on how bilingualism impacts statistical learning abilities. Method: We review the contemporary literature, organized by the age of participants and by task when relevant. Conclusions: We note that there are many discrepant findings within this nascent field, although some trends have emerged. For instance, differences in performance may be attributed to factors such as age of acquisition. However, we note that the state of the field does not yet permit firm clinical recommendations.
