School-Based Speech-Language Pathologists' Engagement With Evidence-Based Practice: An Update With Implications for Implementation Research

PURPOSE

We replicated a prior survey study (Hoffman et al., 2013) to document current evidence-based practice (EBP) patterns as reported by school-based speech-language pathologists (SLPs) during the 2021-2022 school year.

METHOD

Via an online survey, SLPs reported their training experiences and needs, workplace resources, and frequency of engagement in EBP activities.

RESULTS

A total of 889 SLPs in 50 states participated in the survey. Results revealed that 19% of seasoned SLPs (with more than 10 years since last degree) had no formal training in EBP, 22% of SLPs worked in school districts with official EBP procedural guidelines, and 36% had scheduled time in their work week to support EBP activities. Early career (EC) professionals were more likely than seasoned career (SC) professionals to pose and research one or more EBP questions per year and to read journal articles about assessment and treatment. The gap in article use by experience groups was larger than a decade ago. Like prior survey results, the majority of SLPs read zero to four American Speech-Language-Hearing Association (ASHA) journal articles on assessment or intervention per year, with similar results for reading non-ASHA journal articles.

CONCLUSIONS

Although the past decade has fostered some positive increases in the use of EBP resources and engagement in EBP activities, there continues to be a need for additional training and support for school-based SLPs to fully implement EBP. Training and implementation support should account for differences in training preferences and workplace resources and address differentiation of reported practices by EC versus SC professionals. Further implications for implementation science in schools are provided.

Subtract Before You Add: Toward the Development of a De-Implementation Approach in School-Based Speech Sound Therapy

PURPOSE

It is often difficult for school-based speech-language pathologists (SLPs) to prioritize implementing new practices for children with speech sound disorders (SSDs), given burgeoning caseloads and the myriad of other workload tasks. We propose that de-implementation science is equally as important as implementation science. De-implementation science is the recognition and identification of areas that are of "low-value and wasteful." Critically, the idea of de-implementation suggests that we first remove something from a clinician's workload before requesting that they learn and implement something new.

METHOD

Situated within the Sustainability in Healthcare by Allocating Resources Effectively (SHARE) framework, we review de-implementation science and current speech sound therapy literature to understand the mechanisms behind continuous use of practices that are no longer supported by science or legislation. We use vignettes to highlight real-life examples that clinicians may be facing in school-based settings and to provide hypothetical solutions, resources, and/or next steps to these common challenges.

RESULTS

By focusing on Phase 1 of the SHARE framework, we identified four primary practices that can be de-implemented to make space for new evidence-based techniques and approaches. These four practices were determined based on an in-depth review of SLP-based survey research: (a) overreliance on speech sound norms for eligibility determinations, (b) the omission of phonological processing skills within evaluations, (c) homogeneity of service delivery factors, and (d) the use of only one treatment approach for all children with SSDs.

CONCLUSIONS

De-implementation will take work and may lead to some difficult discussions. Implementing a framework, such as SHARE, can guide SLPs toward a reduction in workloads and improved outcomes for children with SSDs.

What Is Clinical Evidence in Speech-Language Pathology? A Scoping Review

PURPOSE

Two disparate models drive American speech-language pathologists' views of evidence-based practice (EBP): the American Speech-Language-Hearing Association's (2004a, 2004b) and Dollaghan's (2007). These models discuss evidence derived from clinical practice but differ in the terms used, the definitions, and discussions of its role. These concepts, which we unify as clinical evidence, are an important part of EBP but lack consistent terminology and clear definitions in the literature. Our objective was to identify how clinical evidence is described in the field.

METHOD

We conducted a scoping review to identify terms ascribed to clinical evidence and their descriptions. We searched the peer-reviewed, accessible, speech-language pathology intervention literature from 2005 to 2020. We extracted the terms and descriptions, from which three types of clinical evidence arose. We then used an open-coding framework to categorize positive and negative descriptions of clinical expertise and summarize the role of clinical evidence in decision making.

RESULTS

Seventy-eight articles included a description of clinical evidence. Across publications, a single term was used to describe disparate concepts, and the same concept was given different terms, yet the concepts that authors described clustered into three categories: clinical opinion, clinical expertise, and practice-based evidence, with each described as distinct from research evidence, and separate from the process of clinical decision making. Clinical opinion and clinical expertise were intrinsic to the clinician. Clinical opinion was insufficient and biased, whereas clinical expertise was a positive multidimensional construct. Practice-based evidence was extrinsic to the clinician-the local clinical data that clinicians generated. Good clinical decisions integrated multiple sources of evidence.

CONCLUSIONS

These results outline a shared language for SLPs to discuss their clinical evidence with researchers, families, allied professionals, and each other. Clarification of the terminology, associated definitions, and the contributions of clinical evidence to good clinical decision-making informs EBP models in speech-language pathology.

Assessment of caregivers' perspectives regarding speech-language services in Saudi Arabia during COVID-19

Background

As a consequence of stay-at-home and other lockdown measures, such as social distancing, all health care service provisions during the COVID-19 pandemic have been affected, including the provision of speech therapy. Telehealth services can play a major role in maintaining access to health care, help speech and language pathologists (SLPs) overcome physical barriers by providing patients and caregivers with access to health care, and limit the discontinuity of patient care. To have a better understanding of the changes that have occurred in these services during COVID-19, this research was conducted to explore the nature and current situation of speech-language services in Saudi Arabia based on caregivers’ perspectives. It also investigated whether changes have occurred in these services during the COVID-19 lockdown. The study also determined the perception of caregivers in delivering SLS sessions remotely.

Method

A cross-sectional study was conducted with 385 caregivers in Saudi Arabia. An online survey asked whether children were experiencing any SLS problems and if they had received any intervention. The survey also assessed the perception of changes in service during the COVID-19 lockdown and the perceptions, acceptance, and willingness of the caregivers to deliver telehealth speech services in Saudi Arabia.

Results

About 50% of the respondents had or were suspected to have a child with SLS problems, and just over half of them had accessed SLS services. Most of the respondents reported suspension of therapy sessions as a response to the COVID-19 pandemic. While the respondents had little experience using telehealth prior to the pandemic, they generally showed a willingness to use telehealth in therapy sessions, expressing a preference for video calls over other options.

Conclusion

The study revealed that SLS services in Saudi Arabia are limited and that accessing these services is challenging. Alternative service delivery using remote services could help caregivers overcome such challenges. When telehealth was introduced as an option for service delivery, the caregivers showed welcoming responses, particularly with video calls.

A qualitative exploration of speech-language pathologists' intervention and intensity provision for children with phonological impairment

PURPOSE

The aim of this study was to explore the reasons behind speech-language pathologists' (SLPs') current clinical practices (intervention and intensity provision) for children (0-18 years) with phonological impairment.

METHOD

Three focus groups each with five SLPs and six 1:1 interviews with SLP managers from one region of the UK (n = 21) were carried out. A thematic analysis was undertaken.

RESULT

SLPs often used an eclectic mix of familiar approaches with easily-accessible therapy materials. SLPs only reported deviating from their core approach if the child did not progress in therapy. Mixed responses were gathered on the perceived feasibility of transferring evidence-based intervention intensities into clinical practice. The importance of parents to increase intensity provision at home was noted. Barriers to SLPs' evidence-based decision-making included: time; confidence levels; service-related restrictions and; difficulty replicating research in practice. Having peer support and access to decision-making pathways and manualised intervention protocols were considered ways to overcome these barriers.

CONCLUSION

There is a research-practice gap in which SLPs' current practices are driven by organisational factors, their own preferences and child-specific factors. To narrow this gap, SLPs suggested the development of time-saving, evidence-based tools.

Treating Childhood Speech Sound Disorders: Current Approaches to Management by Australian Speech-Language Pathologists

Purpose This study explored the intervention processes used by speech-language pathologists (SLPs) to treat children with speech sound disorders (SSDs). Method Semistructured, individual, in-depth interviews were conducted with 11 Australian SLPs. Inductive content analysis was used to classify the data to provide a description of current intervention processes for children with SSDs. Results Three main factors were identified relating to the intervention processes used by SLPs: (a) target selection, (b) therapy approaches, and (c) structural and procedural aspects of therapy sessions, including feedback. The findings revealed that SLPs often combine elements of four therapies: the minimal pairs approach, traditional articulatory approaches, auditory discrimination, and Cued Articulation. Initial therapy targets typically aligned with a developmental approach or were functional speech targets with meaningful relevance to the child and their family. Conclusions These findings contribute to the current state of knowledge about the intervention processes used by SLPs for children with SSDs. The use of hybrid speech pathology therapies, which combined elements of favored approaches, was common. Hybrid methods were intended to help tailor the interventions to individual needs. Client needs were highly prioritized by SLPs and influenced their choice of therapy targets and therapy approaches.

Clinical Reasoning for Speech Sound Disorders: Diagnosis and Intervention in Speech-Language Pathologists' Daily Practice

Purpose This study aims to give an insight in clinical reasoning (diagnosis and intervention) of speech-language pathologists (SLPs) in the Netherlands for children with speech sound disorder (SSD). Method The study featured a mixed-method (qualitative and quantitative) design. Semistructured interviews containing nondirective, open-ended questions were conducted with 33 SLPs, which were analyzed using a constant comparative analysis. Other SLPs (137) filled out a questionnaire on the same topics. Multiple-choice questions were analyzed by descriptive frequencies, while open-ended questions were analyzed thematically. Results The results indicate that SLPs use a variety of assessments to diagnose SSD, complemented by observation and, often, case history. In total, 85 different diagnostic labels were reported. The choice of intervention is based on what is appealing to the child and what matches his or her age as well as on the specific diagnosis and severity. Interventions are used for multiple speech disorders, and according to SLPs, parents play a large role in diagnostics and intervention. Conclusion These results reveal the need for (a) a clear and consistent terminology of diagnoses in the field of pediatric SSD, (b) a fast and easy-to-administer comprehensive differential diagnostic instrument in combination with an instrument to assess participation in everyday life, and (c) a tool to conduct a case history online.

Participant reported outcomes of a community of practice about social participation for speech-language pathologists in aphasia rehabilitation

Purpose: Because of their communication difficulties, persons with aphasia are at risk of not fully participating in significant activities after rehabilitation. Speech-language pathologists can contribute to support optimal social participation in rehabilitation. A community of practice (CoP) was designed to provide motivated clinicians with opportunities to acquire knowledge and reflect on social participation within aphasia rehabilitation. The aim of this study was to describe the outcomes of this CoP according to the perspectives of speech-language pathologist participants.Methods: Semi-structured individual interviews were conducted 4 to 10 weeks after the end of the CoP with 13 speech-language pathologist participants. Analyses were guided by grounded theory.Results: Participants perceived that the CoP experience contributed to a better alignment of their practice with the ideal end purpose of optimizing social participation. A sense of community emerged among CoP members, who collectively reflected on their practice. Participants stated feeling equipped to adopt new practices, adopting new practices for optimizing social participation, and/or advocating for better services for persons with aphasia. They felt increased confidence, motivation, well-being, and/or energy towards their practice.Conclusions: CoPs can help speech-language pathologists to more confidently practice with the goal of optimizing the social participation of persons with aphasia.Implications for rehabilitationSpeech-language pathologists in aphasia rehabilitation, as a result of being involved in a community of practice (CoP) about social participation, may offer more evidence-based services aiming at optimizing the social participation of persons with aphasia.Markers of a successful CoP may include participants' increased feelings of confidence, motivation, well-being, and/or energy towards their practice.CoPs can be used for continuing education purposes and support the development of clinical expertise among professionals, such as speech-language pathologists in aphasia rehabilitation.

Turkish stimulability treatment program for children with speech sound disorders: a preliminary study

PURPOSE

The objective of this study was to create a stimulability treatment program in Turkish language that targets Turkish consonants and vowels and to present the preliminary findings of the effectiveness of the program in a small group of Turkish children with speech sound disorder (SSD).

METHOD

Twenty-two children with SSD participated in the study. The Turkish Articulation and Phonology Test (SST) was used in the assessment of children. Intelligibility ratings were completed by their caregivers through the Turkish version of Intelligibility in Context Scale (ICS), and the stimulability assessments were completed. Stimulability intervention were given for a total of 12 sessions. Comparisons were made between the pre- and post-test results of children, and the preliminary data of treatment efficacy were collected.

RESULTS

The data analysis showed a significant difference in the total number of articulation errors of children between Time 1 and Time 2 (p < .0001), a statistically significant difference in auditory discrimination scores between the two measurements, (p < .05), and an increase in stimulability ratings from Time 1 to Time 2.

CONCLUSION

These findings provide initial data on the positive effect of the Turkish stimulability treatment program for children with SSD. This preliminary study would contribute toward designing the main trial for an evidence-based study for the Turkish stimulability treatment program, thereby leading to better practices in SSD.

Exploring the Overlap Between Dyslexia and Speech Sound Production Deficits

Purpose

Children with dyslexia have speech production deficits in a variety of spoken language contexts. In this article, we discuss the nature of speech production errors in children with dyslexia, including those who have a history of speech sound disorder and those who do not, to familiarize speech-language pathologists with speech production-specific risk factors that may help predict or identify dyslexia in young children.

Method

In this tutorial, we discuss the role of a phonological deficit in children with dyslexia and how this may manifest as speech production errors, sometimes in conjunction with a speech sound disorder but sometimes not. We also briefly review other factors outside the realm of phonology that may alert the speech-language pathologist to possible dyslexia.

Results

Speech-language pathologists possess unique knowledge that directly contributes to the identification and remediation of children with dyslexia. We present several clinical recommendations related to speech production deficits in children with dyslexia. We also review what is known about how and when children with speech sound disorder are most at risk for dyslexia.

Conclusion

Speech-language pathologists have a unique opportunity to assist in the identification of young children who are at risk for dyslexia.

Processes and challenges in clinical decision-making for children with speech-sound disorders

BACKGROUND

Children with speech-sound disorders (SSD) constitute a significant proportion of speech-language pathologists' (SLPs) caseloads. Previous research has investigated the clinical practice of SLPs intervening with children with SSD; however, little is known about the clinical decision-making underpinning their practice.

AIMS

The clinical decision-making of SLPs working with children with SSD was explored to understand how their clinical decisions were influenced by: (1) beliefs about what works in therapy; (2) prior clinical experience; and (3) client and service-related variables.

METHODS & PROCEDURES

Semi-structured, individual, in-depth interviews were conducted with 11 SLPs. Inductive thematic analysis was used to identify and explore key ideas and themes.

OUTCOMES & RESULTS

Four themes emerged: (1) clinical decision-making procedures were highly individualized; (2) parental involvement was viewed as central to the success and progression of therapy; (3) therapy procedures were influenced by practice-setting constraints; and (4) engaging in evidence-based practice within clinical settings was perceived as challenging.

CONCLUSIONS & IMPLICATIONS

In clinical settings, a range of factors influence decision-making and therapy provided by SLPs to children with SSD. These SLPs had a high regard for clients' values and preferences. Prior clinical experiences also shaped clinical practice. Clinical decision-making was influenced by practice-setting constraints. SLPs are under pressure in their workplaces and are struggling to manage the competing demands on their time. Large clinical caseloads, heavy workloads, current service-delivery models and changing family structures are all impacting on the provision of therapy to children with SSD and therapy outcomes. As a profession, there is a need to consider these barriers and identify ways to overcome them in order to assist SLPs to routinely adopt the highest standards of clinical practice for children with SSD.

Intervention for children with phonological impairment: Knowledge, practices and intervention intensity in the UK

BACKGROUND

Across the world, research has shown that intervention for children with phonological impairment can be both effective and efficient. However, it has also raised concerns about the translation of this evidence to practice, highlighting questions around clinician knowledge and the understanding of approaches, and the intensity of intervention provided within real-life clinical contexts.

AIMS

To investigate the clinical management of phonological impairment by speech and language therapists (SLTs) in the United Kingdom (UK).

METHODS & PROCEDURES

An anonymous, UK-wide, online survey was developed using Qualtrics. The target audience were UK-based SLTs who worked with children with phonological impairment. The following topics were explored: (1) SLTs' understanding of intervention approaches; (2) SLTs' use of intervention approaches to treat phonological impairment; and (3) SLTs' provision of intervention intensity for children with phonological impairment.

OUTCOMES & RESULTS

A total of 166 responses were analyzed. To remediate phonological impairment, SLTs most commonly used speech discrimination (79.5%), conventional minimal pairs (77.3%), phonological awareness therapy (75.6%) and traditional articulation therapy (48.4%). Participants least frequently used the complexity approaches targeting the empty set (82.9%) and two- to three-element clusters (75%) as well as the cycles approach (75.6%). Results also showed that some SLTs were uncertain of what the empty set and two- to three-element clusters approaches entailed. In terms of intervention intensity, participants predominantly provided intervention once per week (69%) for a total of 9-12 sessions (ranging from five to 30 sessions, 71.5%) and elicited targets 10-30 times in single words per session (59.4%) in sessions lasting 21-30 min (41.4%).

CONCLUSIONS & IMPLICATIONS

The most commonly used intervention approaches identified in the current survey (i.e., speech discrimination, conventional minimal pairs and phonological awareness therapy) may be used eclectically by SLTs, which could impact upon the effectiveness and efficiency of treatment for phonological impairment. The current study also highlighted that almost half the participants always/often used traditional articulation therapy to remediate phonological impairment, even though this approach has been found to be less effective for this difficulty. Additionally, it appears that the currently provided intervention intensity for phonological impairment in the UK is significantly lower than what is indicated in the literature. Therefore, a research-practice gap exists for SLTs in the UK working with children with phonological impairment.

Implementing Evidence-Based Practice: Selecting Treatment Words to Boost Phonological Learning

Purpose

Word selection has typically been thought of as an inactive ingredient in phonological treatment, but emerging evidence suggests that word selection is an active ingredient that can impact phonological learning. The goals of this tutorial are to (a) review the emerging single-subject evidence on the influence of word characteristics on phonological learning in clinical treatment, (b) outline hypotheses regarding the mechanism of action of word characteristics, and (c) provide resources to support clinicians incorporating word selection as an active ingredient in their approach to phonological treatment.

Method

Research demonstrating the influence of the word frequency, neighborhood density, age of acquisition, and lexicality of treatment stimuli on phonological learning is summarized. The mechanism of action for each characteristic is hypothesized. Methods from the research studies are used to create a free set of evidence-based treatment materials targeting most of the mid-8 and late-8 consonants.

Results

Clinicians have numerous evidence-based options to consider when selecting stimuli for phonological treatment including (a) high-frequency and high-density words, (b) low-frequency and high-density words, (c) high-frequency and mixed-density words, (d) low-frequency and late-acquired words, and (e) nonwords.

Conclusion

Incorporating word characteristics into phonological treatment may boost phonological learning.

Fostering Full Implementation of Evidence-Based Practice

Evidence-based practice (EBP) is a widely endorsed concept, but many occupational therapy practitioners would like to be more informed and supported in its full implementation. They need information on the evolving definitions and concepts of EBP, encouragement to develop and adopt EBP models that link to occupational therapy's professional values, and methods that translate evidence into answers for clinical questions. This column discusses these needs and makes recommendations to the American Occupational Therapy Association for addressing them.

Parent-implemented home therapy programmes for speech and language: a systematic review

BACKGROUND

Parent-delivered home programmes are frequently used to remediate speech and language difficulties in young children. However, the evidence base for this service delivery model is limited.

AIMS

The aim of this systematic review is to investigate the effectiveness of parent-implemented home programmes in facilitating the development of children's speech and language skills, and to evaluate the cost-effectiveness and feasibility of this service delivery method.

METHODS & PROCEDURES

A systematic search of the PsycINFO, CINAHL and ERIC databases was conducted. Quality appraisal of individual studies was conducted. Findings from each of the studies were then integrated to report on outcomes for the child, the parent and the service.

OUTCOMES & RESULTS

There is preliminary evidence that home programmes can lead to growth in a child's speech and language skills and are more effective than no intervention, provided the home programmes are used with high dosage rates and direct parent training.

CONCLUSIONS & IMPLICATIONS

Home programmes are a potentially useful service delivery model, but caution should be exercised when considering their use to address broader service delivery challenges. Further high-level evidence is needed across all facets of this service delivery model.

Efficacious Treatment of Children With Childhood Apraxia of Speech According to the International Classification of Functioning, Disability and Health

There is increasing evidence for treatment approaches designed for children with childhood apraxia of speech (CAS). Despite this, no treatment has conclusive evidence to date. The CAS population is heterogeneous, with children presenting with varying symptom profiles, severity levels, and comorbidities. Consequently, treatment planning for children with CAS represents a clinical challenge. To assist clinicians in providing optimal care, this paper uses the International Classification of Functioning, Disability and Health (ICF) as a framework for identifying the body structures and functions, activities, and personal/environmental factors that should be considered when working with children with CAS. Evidence-based interventions are described and resources outlined to help guide the treatment planning process.

Quality of Mobile Phone and Tablet Mobile Apps for Speech Sound Disorders: Protocol for an Evidence-Based Appraisal

Background

Although mobile apps are readily available for speech sound disorders (SSD), their validity has not been systematically evaluated. This evidence-based appraisal will critically review and synthesize current evidence on available therapy apps for use by children with SSD.

Objective

The main aims are to (1) identify the types of apps currently available for Android and iOS mobile phones and tablets, and (2) to critique their design features and content using a structured quality appraisal tool.

Methods

This protocol paper presents and justifies the methods used for a systematic review of mobile apps that provide intervention for use by children with SSD. The primary outcomes of interest are (1) engagement, (2) functionality, (3) aesthetics, (4) information quality, (5) subjective quality, and (6) perceived impact. Quality will be assessed by 2 certified practicing speech-language pathologists using a structured quality appraisal tool. Two app stores will be searched from the 2 largest operating platforms, Android and iOS. Systematic methods of knowledge synthesis shall include searching the app stores using a defined procedure, data extraction, and quality analysis.

Results

This search strategy shall enable us to determine how many SSD apps are available for Android and for iOS compatible mobile phones and tablets. It shall also identify the regions of the world responsible for the apps’ development, the content and the quality of offerings. Recommendations will be made for speech-language pathologists seeking to use mobile apps in their clinical practice.

Conclusions

This protocol provides a structured process for locating apps and appraising the quality, as the basis for evaluating their use in speech pathology for children in English-speaking nations.

Speech-language pathologists' practices regarding assessment, analysis, target selection, intervention, and service delivery for children with speech sound disorders

A survey of 231 Australian speech-language pathologists (SLPs) was undertaken to describe practices regarding assessment, analysis, target selection, intervention, and service delivery for children with speech sound disorders (SSD). The participants typically worked in private practice, education, or community health settings and 67.6% had a waiting list for services. For each child, most of the SLPs spent 10-40 min in pre-assessment activities, 30-60 min undertaking face-to-face assessments, and 30-60 min completing paperwork after assessments. During an assessment SLPs typically conducted a parent interview, single-word speech sampling, collected a connected speech sample, and used informal tests. They also determined children's stimulability and estimated intelligibility. With multilingual children, informal assessment procedures and English-only tests were commonly used and SLPs relied on family members or interpreters to assist. Common analysis techniques included determination of phonological processes, substitutions-omissions-distortions-additions (SODA), and phonetic inventory. Participants placed high priority on selecting target sounds that were stimulable, early developing, and in error across all word positions and 60.3% felt very confident or confident selecting an appropriate intervention approach. Eight intervention approaches were frequently used: auditory discrimination, minimal pairs, cued articulation, phonological awareness, traditional articulation therapy, auditory bombardment, Nuffield Centre Dyspraxia Programme, and core vocabulary. Children typically received individual therapy with an SLP in a clinic setting. Parents often observed and participated in sessions and SLPs typically included siblings and grandparents in intervention sessions. Parent training and home programs were more frequently used than the group therapy. Two-thirds kept up-to-date by reading journal articles monthly or every 6 months. There were many similarities with previously reported practices for children with SSD in the US, UK, and the Netherlands, with some (but not all) practices aligning with current research evidence.

Evidence-Based Speech-Language Pathology Practices in Schools: Findings From a National Survey

Purpose

This study documented evidence-based practice (EBP) patterns as reported by speech-language pathologists (SLPs) employed in public schools during 2010–2011.

Method

Using an online survey, practioners reported their EBP training experiences, resources available in their workplaces, and the frequency with which they engage in specific EBP activities, as well as their resource needs and future training format preferences.

Results

A total of 2,762 SLPs in 28 states participated in the online survey, 85% of whom reported holding the Certificate of Clinical Competence in Speech-Language Pathology credential. Results revealed that one quarter of survey respondents had no formal training in EBP, 11% of SLPs worked in school districts with official EBP procedural guidelines, and 91% had no scheduled time to support EBP activities. The majority of SLPs posed and researched 0 to 2 EBP questions per year and read 0 to 4 American Speech-Language-Hearing Association (ASHA) journal articles per year on either assessment or intervention topics.

Conclusion

Use of ASHA online resources and engagement in EBP activities were documented to be low. However, results also revealed that school-based SLPs have high interest in additional training and resources to support scientifically based practices. Suggestions for enhancing EBP support in public schools and augmenting knowledge transfer are provided.

Severe Speech Sound Disorders: An Integrated Multimodal Intervention

Purpose

: This study introduces an integrated multimodal intervention (IMI) and examines its effectiveness for the treatment of persistent and severe speech sound disorders (SSD) in young children. The IMI is an activity-based intervention that focuses simultaneously on increasing the quantity of a child's meaningful productions of target words and providing supports to shape the quality of natural speech productions of target sounds by systematically incorporating the full range of each child's communicative repertoire, including augmentative and alternative communication (AAC) systems and natural speech and language.

Method

: A multiple-probe single-subject research design was used to assess the effectiveness of the IMI for 3 boys (ages 4 to 8) with moderate to severe SSD, all of whom used speech-generating AAC.

Results

: All 3 participants demonstrated an increase in the amount of speech they produced (i.e., quantity) and an increase in the production accuracy of their target speech sounds (i.e., quality).

Conclusion

This study demonstrated that simultaneously targeting natural speech and AAC speech using an integrated multimodal approach was effective in producing positive changes in both communication and speech production goals. These findings strongly suggest that integrating multimodal speech-generating AAC with traditional speech intervention was effective at supporting natural speech production for these children.

Pharmacological dosage concepts: how useful are they for educators and speech-language pathologists?

The first part of this response to Baker (2012) examines studies that have attempted to determine the optimum treatment intensity of reading interventions associated with a Response to Intervention (RTI) model of service delivery. In general, the findings indicated that differences in broad measures of intensity (duration and scheduling) did not result in differences in reading outcomes. These non-significant findings and Baker's excellent discussion of all of the factors that impact treatment outcomes led me to question how useful pharmacological dosage concepts are for educators and speech-language pathologists (SLPs). This commentary concludes by acknowledging that the more information available about the active ingredients of treatment episodes, the better able one will be to design effective and efficient interventions to improve speech, language, and literacy.

Evidence-based practice in speech-language pathology curricula: a scoping study

This scoping study investigated how evidence-based practice (EBP) principles are taught in Australian speech-language pathology (SLP) teaching and learning contexts. It explored how Australian SLP university programs: (1) facilitate student learning about the principles of EBP in academic and clinical settings, and (2) self-evaluate their curricula in relation to EBP. The research involved two surveys. Survey 1 respondents were 131 academic staff, program coordinators, and on-campus and off-campus clinical educators. This survey gathered information about EBP teaching and learning in SLP programs as well as future EBP curriculum plans. Survey 2 investigated how clinical educators incorporated EBP into the way they taught clinical decision-making to students. Surveys responses from 85 clinical educators were analysed using descriptive and non-parametric statistics and thematic grouping of open-ended qualitative responses. Both surveys revealed strengths and gaps in integrating EBP into Australian SLP curricula. Perceived strengths were that respondents were positive about EBP, most had EBP training and access to EBP resources. The perceived gaps included the academic staff's perceptions of students' understanding and application of EBP, respondents' understanding of research methodologies, communication and collaboration between academic staff and clinical educators, and a lack of explicit discussion by clinical educators and students of EBP in relation to clients.

Evidence-Based Practice for Children With Speech Sound Disorders: Part 1 Narrative Review

Purpose

This article provides a comprehensive narrative review of intervention studies for children with speech sound disorders (SSD). Its companion paper (Baker & McLeod, 2011) provides a tutorial and clinical example of how speech-language pathologists (SLPs) can engage in evidence-based practice (EBP) for this clinical population.

Method

Studies reporting speech sound intervention for children with SSDs published from 1979 to 2009 were identified and coded.

Results

One hundred thirty-four intervention studies were identified. Intervention typically was conducted by an SLP in a one-to-one individual format for 30- to 60-min sessions 2 to 3 times per week. Total duration of intervention (from assessment to discharge) was reported for 10 studies and ranged from 3 to 46 months. Most studies were either Level IIb (quasi-experimental studies, 41.5%) or Level III (nonexperimental case studies, 32.6%). Single-case experimental design (29.6%) was the most frequently used experimental research design. There were 7 distinct approaches to target selection and 46 distinct intervention approaches, with 23 described in more than 1 publication. Each approach was associated with varying quantities and levels of evidence, according to research design.

Conclusion

Collaborative research reflecting higher levels of evidence using rigorous experimental designs is needed to compare the relative benefits of different intervention approaches.
