Rodgers L, Botting N, Harding S, Cartwright M, Amer-El-khedoud M, Herman R. Shared characteristics of intervention techniques for oral vocabulary and speech comprehensibility in preschool children with co-occurring features of developmental language disorder and speech sound disorder: a systematic review with narrative synthesis. BMJ Open 2024; 14:e081571. [PMID: 39209496 PMCID: PMC11367316 DOI: 10.1136/bmjopen-2023-081571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 07/26/2024] [Indexed: 09/04/2024] Open
Abstract
OBJECTIVES To descriptively compare and contrast intervention techniques for preschool children with features of developmental language disorder (outcome: oral vocabulary) and speech sound disorder (outcome: speech comprehensibility) and analyse them in relation to effectiveness and theory. DESIGN This is a systematic review with narrative synthesis. The process was supported by an expert steering group consisting of relevant professionals and people with lived experience. DATA SOURCES Ovid Emcare, MEDLINE Complete, CINAHL, APA PsycINFO, ERIC, and Communication Source from January 2012 were searched. Relevant studies were obtained from an initial published review (up to January 2012). ELIGIBILITY CRITERIA Interventions for preschool children (80% aged 2:0-5:11 years) with idiopathic speech or language needs; outcomes relating to either oral vocabulary or speech comprehensibility. DATA EXTRACTION AND SYNTHESIS Searches were conducted on 27 January 2023. Two independent researchers screened at abstract and full-text levels. Data regarding intervention content (eg, techniques) and format/delivery (eg, dosage, location) were extracted. Data were synthesised narratively according to the methods of Campbell et al. RESULTS 24 studies were included: 18 for oral vocabulary and 6 for speech comprehensibility. There were 11 randomised controlled trials, 2 cohort studies and 11 case series. Similarities included a focus on input-related techniques and similar therapy activities. Speech studies were more likely to be professional-led and clinic-led, rather than at home and through a parent. Analysis was restricted by heterogeneity in study design and terminology, as well as gaps within intervention reporting. Information deemed important to the expert steering group was missing. CONCLUSIONS Similarities and differences between intervention techniques for oral vocabulary and speech comprehensibility have been identified and synthesised. However, analysis of effectiveness was limited due to issues with study design and heterogeneity within studies. This has implications for the progression of the evidence base within the field. PROSPERO REGISTRATION NUMBER CRD42022373931.

Abstract
Dental caries (tooth decay) is a disease with a significant global burden. Management may necessitate the extraction of teeth to restore oral health. The association between dental extractions and children's speech is unclear, with clinical implications for speech-language pathologists and dentists. This case series describes a prospective study reporting the impact of primary maxillary incisor teeth extraction on speech sound accuracy for three children (C1 aged 5;6 (years; months), C2 aged 4;6, C3 aged 3;10). Their speech was assessed using the Diagnostic Evaluation of Articulation and Phonology (DEAP) and the Intelligibility in Context Scale (ICS) before (T1) and 1 month after dental treatment (T2). Speech analysis included the percentage of consonants correct (PCC) and error-type analyses. Caregiver and child perception of the child's oral health-related quality of life (OHRQoL) were assessed pre- and post-operatively using a modified Scale of Oral Health Outcomes for 5-year-old children (SOHO-5). At T1, all three children scored >1 standard deviation below the mean on normative data in the DEAP. There was no clinically significant change in PCC for any child (C1 T1: 89.6%, T2: 90.6%, C2 T1: 78.0%, T2: 75.9%, C3 T1: 56.1%, T2: 63.1%). OHRQoL measures were improved for C1 by the carergiver report and remained stable for C2 and C3 and all child reports. Speech sound difficulties were present before dental treatment in all participants and extraction of primary maxillary incisors did not significantly impact speech production. Dental extractions appear to be independent from speech production in this case series of preschool children.

Abstract
Importance Children with speech and language difficulties are at risk for learning and behavioral problems. Objective To review the evidence on screening for speech and language delay or disorders in children 5 years or younger to inform the US Preventive Services Task Force. Data Sources PubMed/MEDLINE, Cochrane Library, PsycInfo, ERIC, Linguistic and Language Behavior Abstracts (ProQuest), and trial registries through January 17, 2023; surveillance through November 24, 2023. Study Selection English-language studies of screening test accuracy, trials or cohort studies comparing screening vs no screening; randomized clinical trials (RCTs) of interventions. Data Extraction and Synthesis Dual review of abstracts, full-text articles, study quality, and data extraction; results were narratively summarized. Main Outcomes and Measures Screening test accuracy, speech and language outcomes, school performance, function, quality of life, and harms. Results Thirty-eight studies in 41 articles were included (N = 9006). No study evaluated the direct benefits of screening vs no screening. Twenty-one studies (n = 7489) assessed the accuracy of 23 different screening tools that varied with regard to whether they were designed to be completed by parents vs trained examiners, and to screen for global (any) language problems vs specific skills (eg, expressive language). Three studies assessing parent-reported tools for expressive language skills found consistently high sensitivity (range, 88%-93%) and specificity (range, 88%-85%). The accuracy of other screening tools varied widely. Seventeen RCTs (n = 1517) evaluated interventions for speech and language delay or disorders, although none enrolled children identified by routine screening in primary care. Two RCTs evaluating relatively intensive parental group training interventions (11 sessions) found benefit for different measures of expressive language skills, and 1 evaluating a less intensive intervention (6 sessions) found no difference between groups for any outcome. Two RCTs (n = 76) evaluating the Lidcombe Program of Early Stuttering Intervention delivered by speech-language pathologists featuring parent training found a 2.3% to 3.0% lower proportion of syllables stuttered at 9 months compared with the control group when delivered in clinic and via telehealth, respectively. Evidence on other interventions was limited. No RCTs reported on the harms of interventions. Conclusions and Relevance No studies directly assessed the benefits and harms of screening. Some parent-reported screening tools for expressive language skills had reasonable accuracy for detecting expressive language delay. Group parent training programs for speech delay that provided at least 11 parental training sessions improved expressive language skills, and a stuttering intervention delivered by speech-language pathologists reduced stuttering frequency.

Abstract
PURPOSE The purpose of the study was to investigate child- and intervention-level factors that predict improvements in functional communication outcomes in children with motor-based speech sound disorders. METHOD Eighty-five preschool-age children with childhood apraxia of speech (n = 37) and speech motor delay (n = 48) participated. Multivariable logistic regression models estimated odds ratios and 95% confidence intervals for the association between minimal clinically important difference in the Focus on the Outcomes of Communication Under Six scores and multiple child-level (e.g., age, sex, speech intelligibility, Kaufman Speech Praxis Test diagnostic rating scale) and intervention-level predictors (dose frequency and home practice duration). RESULTS Overall, 65% of participants demonstrated minimal clinically important difference changes in the functional communication outcomes. Kaufman Speech Praxis Test rating scale was significantly associated with higher odds of noticeable change in functional communication outcomes in children. There is some evidence that delivering the intervention for 2 times per week for 10 weeks provides benefit. CONCLUSION A rating scale based on task complexity has the potential for serving as a screening tool to triage children for intervention from waitlist and/or determining service delivery for this population.

Abstract
PURPOSE The current standard for clinical diagnosis of childhood apraxia of speech (CAS) is expert clinician judgment. The psychometric properties of this standard are not well understood; however, they are important for improving clinical diagnosis. The purpose of this study is to determine the extent to which experts agree on the clinical diagnosis of CAS using two cohorts of children with mixed speech sound disorders (SSDs). METHOD Speech samples of children with SSDs were obtained from previous and ongoing research from video recordings of children aged 3-8 years (n = 36) and audio recordings of children aged 8-17 years (n = 56). A total of 23 expert, English-speaking clinicians were recruited internationally. Three of these experts rated each speech sample to provide a description of the observed features and a diagnosis. Intrarater reliability was acceptable at 85% agreement. RESULTS Interrater reliability on the presence or absence of CAS among experts was poor both as a categorical diagnosis (κ = .187, 95% confidence interval [CI] [0.089, 0.286]) and on a continuous "likelihood of CAS" scale (0-100; intraclass correlation = .183, 95% CI [.037, .347]). Reliability was similar across the video-recorded and audio-only samples. There was greater agreement on other diagnoses (such as articulation disorder) than on the diagnosis of CAS, although these too did not meet the predetermined standard. Likelihood of CAS was greater in children who presented with more American Speech-Language-Hearing Association CAS consensus features. CONCLUSIONS Different expert raters had different thresholds for applying the diagnosis of CAS. If expert clinician judgment is to be used for diagnosis of CAS or other SSDs, further standardization and calibration is needed to increase interrater reliability. Diagnosis may require operationalized checklists or reliable measures that operate along a diagnostic continuum. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.23949105.

Abstract
PURPOSE This article presents a large-scale example of culturally responsive assessment and analysis of multilingual Vietnamese-English-speaking children and their family members using the VietSpeech Protocol involving (a) examining all spoken languages, (b) comparing ambient phonology produced by family members, (c) including dialectal variants in the definition of accuracy, and (d) clustering participants with similar language experience. METHOD The VietSpeech participants (N = 154) comprised 69 children (2;0-8;10 [years;months]) and 85 adult family members with Vietnamese heritage living in Australia. Speech was sampled using the Vietnamese Speech Assessment (Vietnamese) and the Diagnostic Evaluation of Articulation and Phonology (English). RESULTS Children's Vietnamese consonant accuracy was significantly higher when dialectal variants were accepted (percentage of consonants correct-dialect [PCC-D]: M = 87.76, SD = 8.18), compared to when only Standard Vietnamese was accepted as the correct production (percentage of consonants correct-standard [PCC-S]: M = 70.34, SD = 8.78), Cohen's d = 3.55 (large effect). Vietnamese voiced plosives, nasals, semivowels, vowels, and tones were more often correct than voiceless plosives and fricatives. Children's Standard Australian English consonant accuracy (PCC-S) was 82.51 (SD = 15.57). English plosives, nasals, glides, and vowels were more often correct than fricatives and affricates. Vietnamese word-initial consonants had lower accuracy than word-final consonants, whereas English consonant accuracy was rarely influenced by word position. Consonant accuracy and intelligibility were highest for children with high proficiency in both Vietnamese and English. Children's consonant productions were most similar to their mothers' than other adults or siblings' productions. Adults' Vietnamese consonants, vowels, and tones were more likely to match Vietnamese targets than their children's productions. CONCLUSIONS Children's speech acquisition was influenced by cross-linguistic, dialectal, maturational, language experience, and environmental (ambient phonology) factors. Adults' pronunciation was influenced by dialectal and cross-linguistic factors. This study highlights the importance of including all spoken languages, adult family members, dialectal variants, and language proficiency to inform differential diagnosis of speech sound disorders and identify clinical markers in multilingual populations.

Abstract
The Intelligibility in Context Scale (ICS) is a parent-report screening tool used to measure parents' perceptions of children's functional intelligibility. This tool has been translated into over 60 languages and found to have a good reliability and validity. The purpose of the current study was to translate the ICS into Sinhala (the ICS-SIN), the main language spoken by the Sinhalese people in Sri Lanka, and to validate it with both typically developing (TD) children and children with repaired cleft lip and/or palate (CLP). The translation process followed the forward-backward-forward method. A total of 88 parents of TD children and children with CLP aged 12-15 years old (TD n = 50, CLP n = 38) completed the ICS-SIN questionnaire. Parents of TD and CLP children reported their children's speech as most intelligible to parents and least intelligible to strangers. The ICS-SIN had high internal consistency for both groups (TD α = 0.87, p < 0.05, CLP α = 0.97, p < 0.05). The ICS-SIN total scores and item scores showed significant correlations, indicating a good construct validity. TD participant group's ICS-SIN average mean scores (M = 4.88, SD = 0.29) were significantly higher compared to the CLP ICS-SIN average mean scores (M = 4.64, SD = 0.67) and varied according to gender in both groups, suggesting good discriminant validity. The ICS-SIN has overall good psychometric properties. Therefore, this tool has the potential to be used as a valid parent-rating screening tool for clinical and research purposes in Sri Lanka.

Abstract
PURPOSE The purpose of this study was to explore the relationship between speech perception, speech production, and vocabulary abilities in children with and without speech sound disorders (SSDs), analyzing the data both by group and continuously. METHOD Sixty-one Australian English-speaking children aged 48-69 months participated in this study. Children's speech production abilities ranged along the continuum from SSDs through to typical speech. Their vocabulary abilities ranged along the continuum from typical to above average ("lexically precocious"). Children completed routine speech and language assessments in addition to an experimental Australian English lexical and phonetic judgment task. RESULTS When analyzing data by group, there was no significant difference between the speech perception ability of children with SSDs and that of children without SSDs. Children with above-average vocabularies had significantly better speech perception ability than children with average vocabularies. When analyzing data continuously, speech production and vocabulary were both significant positive predictors of variance in speech perception ability, both individually in simple linear regression and when combined in multiple linear regression. There was also a significant positive correlation between perception and production of two of the four target phonemes tested (i.e., /k/ and /ʃ/) among children in the SSD group. CONCLUSIONS Results from this study provide further insight into the complex relationship between speech perception, speech production, and vocabulary abilities in children. While there is a clinical and important need for categorical distinctions between SSDs and typically developing speech, findings further highlight the value of investigating speech production and vocabulary abilities continuously and categorically. By capturing the heterogeneity among children's speech production and vocabulary abilities, we can advance our understanding of SSDs in children.

Advancing cluster randomised trials in children’s therapy: a survey of the acceptability of trial behaviours to therapists and parents. Trials 2022; 23:958.

Abstract
Abstract
Background
Randomised controlled trials of non-pharmacological interventions in children’s therapy are rare. This is, in part, due to the challenges of the acceptability of common trial designs to therapists and service users. This study investigated the acceptability of participation in cluster randomised controlled trials to therapists and service users.
Methods
A national electronic survey of UK occupational therapists, physiotherapists, speech and language therapists, service managers, and parents of children who use their services. Participants were recruited by NHS Trusts sharing a link to an online questionnaire with children’s therapists in their Trust and with parents via Trust social media channels. National professional and parent networks also recruited to the survey. We aimed for a sample size of 325 therapists, 30 service managers, and 60 parents. Trial participation was operationalised as three behaviours undertaken by both therapists and parents: agreeing to take part in a trial, discussing a trial, and sharing information with a research team. Acceptability of the behaviours was measured using an online questionnaire based on the Theoretical Framework of Acceptability constructs: affective attitude, self-efficacy, and burden. The general acceptability of trials was measured using the acceptability constructs of intervention coherence and perceived effectiveness. Data were collected from June to September 2020. Numerical data were analysed using descriptive statistics and textual data by descriptive summary.
Results
A total of 345 survey responses were recorded. Following exclusions, 249 therapists and 40 parents provided data which was 69.6% (289/415) of the target sample size. It was not possible to track the number of people invited to take the survey nor those who viewed, but did not complete, the online questionnaire for calculation of response rates. A completion rate (participants who completed the last page of the survey divided by the participants who completed the first, mandatory, page of the survey) of 42.9% was achieved. Of the three specified trial behaviours, 140/249 (56.2%) therapists were least confident about agreeing to take part in a trial. Therapists (135/249, 52.6%) reported some confidence they could discuss a trial with a parent and child at an appointment. One hundred twenty of 249 (48.2%) therapists reported confidence in sharing information with a research team through questionnaires and interviews or sharing routine health data. Therapists (140/249, 56.2%) felt that taking part in the trial would take a lot of effort and resources. Support and resources, confidence with intervention allocation, and sense of control and professional autonomy over clinical practice were factors that positively affected the acceptability of trials. Of the 40 parents, twelve provided complete data. Most parents (18/40, 45%) agreed that it was clear how trials improve children’s therapies and outcomes and that a cluster randomised trial made sense to them in their therapy situation (12/29, 30%).
Conclusions
Using trials to evaluate therapy interventions is, in principle, acceptable to therapists, but their willingness to participate in trials is variable. The willingness to participate may be particularly influenced by their views related to the burden associated with trials, intervention allocation, and professional autonomy.

Abstract
PURPOSE Thousands of technological applications (apps) have emerged in the past decade, yet few studies have examined how apps are used by speech-language pathologists (SLPs), their effectiveness, and SLPs' feelings regarding their use. This study explored how SLPs use apps and their feelings regarding their use in schools, as well as considerations made by SLPs prior to implementing apps in therapy sessions. METHOD A survey was distributed electronically to school-based SLPs in Ohio, yielding 69 valid responses. The study probed SLP demographics, patterns of app use in schools, and feelings toward their use in a school setting. RESULTS Results showed 77% of SLPs reported using apps in their treatment sessions and reported generally positive feelings regarding app use. SLPs considered factors such as age, cognitive ability, and treatment targets when using apps in treatment. SLPs who reported not using apps cited personal preference and price as the most common factors influencing their decision. SLPs also noted concerns about excessive screen time. CONCLUSIONS Results of this study carry clinical implications for future development and assessment of technology to be used for service delivery in schools. Given that the majority of school-based SLPs report using apps with their students, research on the role of apps in supporting learning for speech-language services is urgently needed.

Abstract
PURPOSE Individual-randomized trials are the gold standard for testing the efficacy and effectiveness of drugs, devices, and behavioral interventions. Health care delivery, educational, and programmatic interventions are often complex, involving multiple levels of change and measurement precluding individual randomization for testing. Cluster-randomized trials and cluster-randomized stepped-wedge trials are alternatives where the intervention is allocated at the group level, such as a clinic or a school, and the outcomes are measured at the person level. These designs are introduced along with the statistical implications of similarities among individuals within the same cluster. We also illustrate the parameters that have the most impact on the likelihood of detecting intervention effects, which must be considered when planning these trials. CONCLUSION Cluster-randomized and stepped-wedge designs should be considered by researchers as experimental alternatives to individual-randomized trials when testing speech, language, and hearing care interventions in real-world settings.

Abstract
Purpose There is a shortage of information on evidence-based interventions for supporting young multilingual children. The purpose of this review was to identify interventions that have been evaluated with preschool-age multilingual children with a speech and/or language disorder or who are at risk of poor speech, language, literacy, and/or educational outcomes. Method This review considered speech, language, and early literacy interventions evaluated with preschool-age multilingual children with a speech and/or language disorder or who have been identified as being at risk of language difficulties (PROSPERO ID: 165892). The following electronic databases were searched: EBSCO (CINAHL Plus, ERIC, PsycINFO, Medline, Education) and Linguistics, Language, and Behavior Abstracts. Data were extracted describing article, participant, methodological, and intervention variables, and effect sizes. The Council for Exceptional Children's (CEC) standards for evidence-based practice were used to examine the quality of studies. Results Fifty-six relevant studies were identified in 52 articles and these studies described 4,551 participants who had speech sound disorder (six articles), developmental language disorder (11 articles), or were considered to be at risk (36 articles). The interventions targeted speech production (seven studies), language (45 studies), and early literacy (11 studies) skills. Most studies reported positive effects. Only 15 studies met all quality indicators specified by the CEC (2014) and these described 18 interventions targeting language and literacy skills. The only intervention with sufficient evidence to be considered an evidence-based practice was Nuestros Niños [Our Children] for children's early literacy and phonological awareness skills. Conclusions A number of high-quality studies exist that describe speech, language and/or literacy interventions for preschool-age multilingual children with a speech and/or language disorder, or who have been identified as being at risk of language difficulties. However, there remains limited evidence for specific interventions as to their ability to inform evidence-based practices. Supplemental Material https://doi.org/10.23641/asha.16632649.

Abstract
Purpose Intervention research in speech-language pathology is growing; however, there remains a gap between research and clinical practice. To promote evidence-based practice, stakeholder input may be solicited during the development and evaluation of treatments. One method of evaluating stakeholder input is by subjectively measuring social validity. Social validity probes end users' satisfaction and acceptability of a treatment. Method This review article explores the type and frequency of subjective social validity measures reported in speech-language pathology treatment literature published in American Journal of Speech-Language Pathology; Journal of Speech, Language, and Hearing Research; and Language, Speech, and Hearing Services in Schools from January 2017 through April 2019. In total, 93 treatment studies were included and coded descriptively. Results Of the 93 treatment studies included in this review, 20 reported subjective measures of social validity. The most common method of measurement was questionnaires (n = 19), followed by interviews (n = 5), and direct observation (n = 1). Conclusions Only 21.5% of reviewed speech-language pathology treatment articles from American Speech-Language-Hearing Association journals reported measures of social validity, although it is a crucial component of implementation of evidence-based practice. We urge researchers and journal editors to include social validity measures in treatment literature as we promote the uptake of evidence-based practices and the involvement of stakeholders during the development of evidence-based practices. We also encourage the development of social validity measures that can be validated on individuals with communication disorders.

Abstract
Digital games can make speech therapy exercises more enjoyable for children and increase their motivation during therapy. However, many such games developed to date have not been designed for long-term use. To address this issue, we developed Apraxia World, a speech therapy game specifically intended to be played over extended periods. In this study, we examined pronunciation improvements, child engagement over time, and caregiver and automated pronunciation evaluation accuracy while using our game over a multi-month period. Ten children played Apraxia World at home during two counterbalanced 4-week treatment blocks separated by a 2-week break. In one treatment phase, children received pronunciation feedback from caregivers and in the other treatment phase, utterances were evaluated with an automated framework built into the game. We found that children made therapeutically significant speech improvements while using Apraxia World, and that the game successfully increased engagement during speech therapy practice. Additionally, in offline mispronunciation detection tests, our automated pronunciation evaluation framework outperformed a traditional method based on goodness of pronunciation scoring. Our results suggest that this type of speech therapy game is a valid complement to traditional home practice.

Abstract
AIM To describe uses of the Focus on the Outcomes of Communication Under Six (FOCUS) in research with children with and without various communication disorders since its publication in 2010. METHOD Six databases were searched for the term 'Focus on the Outcomes of Communication Under Six'. With additional searches we ascertained 70 articles, of which 25 met inclusion criteria for full review and data extraction. RESULTS The FOCUS has been used in research across multiple countries, purposes, populations, contexts, and versions. Evaluative studies have described: the development of children's communicative participation skills and factors that impact the development of communicative participation; the impact of specific interventions on communicative participation; how FOCUS captures change relative to measures of impairment; and how FOCUS performs when used at different intervals. Adaptations have included: use of the FOCUS as a descriptive or discriminative tool; use with children outside the validated age range; use of select items; and use with typically developing children. INTERPRETATION The FOCUS is used worldwide in research and practice, and much has been learned about children's communicative participation. Future research is needed to explore the relationship between children's impairments and their communicative participation, develop a FOCUS App, and develop and validate a FOCUS for school-age children.

Abstract
Purpose“Children are the hidden victims of the COVID-19 pandemic” (United Nations Children's Fund, 2020). Timely and effective speech intervention is important to reduce the impact on children's school achievement, ability to make friends, mental health, future life opportunities, and government resources. Prior to the coronavirus disease (COVID-19) pandemic, many Australian children did not receive sufficient speech-language pathology (SLP) services due to long waiting lists in the public health system. COVID-19 restrictions exacerbated this issue, as even children who were at the top of lengthy SLP waiting lists often received limited services, particularly in rural areas. To facilitate children receiving speech intervention remotely during the COVID-19 pandemic, evidence from randomized controlled trials regarding three technological solutions are examined: (a) Phoneme Factory Sound Sorter (Sound Start Study), (b) Waiting for Speech Pathology website, and (c) Apraxia World.ConclusionsFor the first two technological solutions, there were similar gains in speech production between the intervention and control groups, whereas, for the third solution, the average magnitude of treatment effect was comparable to face-to-face SLP therapy. Automated therapy management systems may be able to accelerate speech development and support communication resilience to counteract the effects of the COVID-19 restrictions on children with speech sound disorders. Technology-based strategies may also provide a potential solution to the chronic shortage of SLP services in rural areas into the future.

Randomized controlled trial comparing Parent Led Therapist Supervised Articulation Therapy (PLAT) with routine intervention for children with speech disorders associated with cleft palate. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2020; 55:639-660. [PMID: 32725861 DOI: 10.1111/1460-6984.12542] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/03/2019] [Revised: 04/23/2020] [Accepted: 05/08/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND A total of 68% of pre-school children with cleft palate have speech problems requiring speech therapy. There is a lack of access to regular targeted therapy. Parent training leads to positive outcomes in early communication skills in cleft palate and non-cleft speech disorders. Connected health has been used to address inadequate access to therapy, providing intervention to those who would not otherwise receive therapy. AIMS To evaluate the speech, activity and participation outcomes of Parent Led, Therapist Supervised, Articulation Therapy (PLAT) compared with routine speech therapy intervention in parent-child dyads. METHODS & PROCEDURES A total of 44 children, aged 2.9-7.5 years, were included in a two-centre, two-phase randomized controlled trial. Informed consent and assent were obtained. Participants and speech and language therapists (SLTs) were unblinded to the groups. Parents, in the parent-trained group (n = 23), attended 2 days' training, received a detailed speech therapy programme, and undertook intervention over 12 weeks supported by the cleft specialist SLT using FaceTime and one face-to-face session. In the control arm (n = 21), parent-child dyads received six therapy sessions over 12 weeks with a research SLT, comparable with usual care. Speech recordings were undertaken pre- and post-intervention. Percent consonant correct (PCC) was analysed by external SLTs blinded to the time and group. Activity and participation were measured using the Intelligibility in Context Scale (ICS) and Focus on Outcomes for Children Under Six (FOCUS) questionnaire. OUTCOMES & RESULTS There was no evidence of an interaction between Time and Group or an overall statistical difference between groups for PCC scores. There was a statistically significant difference over time for both groups (words: p < 0.002; confidence interval (CI) = 9.38-16.27; d = 0.57; sentences: p < 0.002; CI = 16.04-25.97; d = 0.23). Effect sizes were medium for words and small for sentences. For intelligibility and participation, there was no evidence of an interaction between Time and Group or an overall statistical difference between groups. A statistically significant difference over time was found for intelligibility (F = 29.97, d.f. = 1, 42, p < 0.001, 95 % CI = 1.45-3.15 d = 0.46) and for participation (F = 14.19, d.f. = 1, 41, p < 0.001 95% CI = 7.63-25.03; d = 0.36) with FOCUS results indicating clinically meaningful (parent-led group) and significant (control group) change in participation. CONCLUSIONS & IMPLICATIONS PLAT can be as effective as routine care in changing speech, activity and participation outcomes for children with cleft palate, when supported by a specialist cleft SLT using connected health. What this paper adds What is already known on this subject Over 50% of children with cleft palate require speech therapy. However, there is a lack of timely, accessible speech therapy services in the UK and Ireland. Previous studies have shown that parents can deliver therapy effectively, and that connected health can support the delivery of speech therapy. This study aims to provide evidence that parent-led therapy with the supervision of a specialist cleft therapist using FaceTime is effective. What this paper adds to existing knowledge This randomized controlled trial indicates that parents can be trained to deliver therapy for children with cleft palate speech disorders, under the supervision of an SLT. This approach results in improved speech, activity and participation outcomes similar to routine care. What are the potential or actual clinical implications of this work? This study indicates that both parent-led articulation therapy and routine care showed meaningful gains in speech, activity and participation, and that parent-led articulation therapy when supported by a cleft SLT using connected health could be an additional service delivery model for children with cleft palate speech disorders.

Abstract
INTRODUCTION High demand for speech-language pathology means children sometimes wait over 12 months for services, missing out on timely support. Waiting can be a time of stress, concern, and powerlessness for caregivers. Provision of information via a website may support families and encourage active waiting. OBJECTIVE The aim of this study was to compare children's speech, intelligibility, language, and literacy outcomes, and caregivers' satisfaction and empowerment in active versus passive waiting conditions. METHODS Ninety-seven preschool-aged children referred to a community health speech-language pathology service in Australia were screened for eligibility. Eligible children (n =42) with speech/language difficulties were randomly allocated to: (a) active waiting (provision of a purpose-built website; n = 20), or (b) passive waiting (control group; n = 22). Pre- and post-assessments (after 6 months on a waiting list) were completed with children and caregivers by a speech-language pathologist blinded to group allocations. RESULTS Intention to treat (n =36) and per-protocol analyses (n =30) were conducted to measure group differences in child and caregiver outcomes at post-assessment using one-way ANCOVA, controlling for baseline scores. There were no statistically significant differences between groups for children's speech, intelligibility, language, and literacy, or caregivers' empowerment and satisfaction. Children in both groups made minimal gains over 6 months. CONCLUSIONS Provision of an active waiting website did not lead to statistically significant change in child or caregiver outcomes, and children in both groups made little progress over a 6-month period. Early speech-language pathology intervention delivered with appropriate dosage is needed to optimise children's outcomes. Until timely and effective speech-language pathology intervention can be provided for all who need it, provision of early assessments may be beneficial. There remains a need for effective ways to support children and families on waiting lists.

Abstract
Purpose: To compare children's speech, language and early literacy outcomes, and caregivers' empowerment and satisfaction following provision of 12 sessions of direct intervention (therapy), or face-to-face advice or a purpose-built website (device) while waiting for therapy.Method: A four-stage randomised controlled trial was undertaken involving three- to six-year-old children referred to speech-language pathology waiting lists at two Australian community health centres over eight months (n = 222). Stage 1 (screening): 149 were eligible to participate. Stage 2 (pre-assessment): 117 were assessed. Stage 3 (intervention): 110 were randomised to advice (33), device (39) or therapy (38). Stage 4 (post-assessment): 101 were re-assessed by a speech-language pathologist blinded to the intervention condition.Result: After controlling for baseline levels, children's speech (percentage of consonants correct) was significantly higher in the therapy group compared to the advice and device conditions. Caregivers' satisfaction was also significantly higher in the therapy condition compared to the device condition. There were no significant differences between the three conditions for children's intelligibility, language and early literacy or caregivers' empowerment.Conclusion: Therapy resulted in significantly higher speech outcomes than the advice and device conditions and was associated with significantly greater caregiver satisfaction. Provision of a website containing evidence-based material or a single session of advice may be a viable alternative while children wait for therapy targeting intelligibility, language and early literacy, and to empower caregivers.

Abstract
Purpose This article reports on the effectiveness of a novel tablet-based approach to phonological intervention and compares it to a traditional tabletop approach, targeting children with phonologically based speech sound disorders (SSD). Method Twenty-two Portuguese children with phonologically based SSD were randomly assigned to 1 of 2 interventions, tabletop or tablet (11 children in each group), and received intervention based on the same activities, with the only difference being the delivery. All children were treated by the same speech-language pathologist over 2 blocks of 6 weekly sessions, for 12 sessions of intervention. Participants were assessed at 3 time points: baseline; pre-intervention, after a 3-month waiting period; and post-intervention. Outcome measures included percentage of consonants correct, percentage of vowels correct, and percentage of phonemes correct. A generalization of target sounds was also explored. Results Both tabletop and tablet-based interventions were effective in improving percentage of consonants correct and percentage of phonemes correct scores, with an intervention effect only evident for percentage of vowels correct in the tablet group. Change scores across both interventions were significantly greater after the intervention, compared to baseline, indicating that the change was due to the intervention. High levels of generalization (60% and above for the majority of participants) were obtained across both tabletop and tablet groups. Conclusions The software proved to be as effective as a traditional tabletop approach in treating children with phonologically based SSD. These findings provide new evidence regarding the use of digital materials in improving speech in children with SSD. Supplemental Material https://doi.org/10.23641/asha.9989816.

Abstract
Purpose The aim of this study was to investigate children's acquisition of Vietnamese speech sounds. Method Participants were 195 children aged 2;2-5;11 (years;months) living in Northern Viet Nam who spoke Vietnamese as their 1st language. Single-word samples were collected using the Vietnamese Speech Assessment (Phạm, Le, & McLeod, 2016) to measure accuracy of consonants, semivowels, vowels, and tones. Results Percentage of consonants correct for children aged 2;0-2;5 was 46.39 (SD = 7.95) and increased to 93.13 (SD = 6.13) for children aged 5;6-5;11. The most difficult consonants were /ɲ, s, z, x/. Percentage of semivowels correct for children aged 2;0-2;5 was 70.74 (SD = 14.38) and increased to 99.60 (SD = 1.55) for children aged 5;6-5;11. Percentage of vowels correct for children aged 2;0-2;5 was 91.93 (SD = 3.13) and increased to 98.11 (SD = 2.79) for children aged 5;6-5;11. Percentage of tones correct for children aged 2;0-2;5 was 91.05 (SD = 1.42) and increased to 96.65 (SD = 3.42) for children aged 5;6-5;11. Tones 1, 2, 5, and 6 were acquired by the youngest age group, whereas Tone 3 (creaky thanh ngã) and Tone 4 (dipping-rising thanh hỏi) did not achieve 90% accuracy by the oldest age group. Common phonological patterns (> 10%) were fronting, stopping, deaspiration, aspiration, and semivowel deletion for children aged 2;0-3;11 and were fronting and deaspiration for children aged 4;0-5;11. Conclusion This is the 1st comprehensive study of typically developing Northern Vietnamese children's speech acquisition and provides preliminary data to support the emerging speech-language pathology profession in Viet Nam.

Abstract
Purpose Many educators and speech-language pathologists have difficulty providing effective interventions to the growing population of d/Deaf and hard-of-hearing (DHH) learners who use more than 1 language. The purpose of this review article was to identify evidence-based interventions for speech, language, and literacy used with DHH multilingual learners (DMLs), monolingual DHH learners, and hearing bilingual learners without hearing loss. Interventions used with these groups can inform the practice of professionals providing services to DMLs. Method This review article considered speech, language, and literacy interventions used with DHH and hearing bilingual learners from birth to 21 years of age. The following electronic databases were searched: Academic Search Complete/EBSCO (CINAHL, Education, ERIC), Linguistics & Language Behavior Abstracts, PsycINFO, and PubMed. Data describing article, participant, methodological, and intervention variables were extracted from studies. The methodological quality of studies was examined using the Council for Exceptional Children's (2014) standards for evidence-based practice in special education. Results A total of 144 studies were reviewed, describing over 9,370 learners aged 1.8-22.0 years. Two studies investigated DMLs, 76 investigated DHH learners, and 67 investigated hearing bilingual learners. A total of 146 different interventions were examined. Most studies reported positive effects. Only 17 studies met all quality indicators specified by the Council for Exceptional Children (2014): 7 examined DHH learners, and 10 examined hearing bilingual learners. There was insufficient evidence for any intervention to be considered an evidence-based intervention, although 6 could potentially contribute to evidence-based practice. Conclusions No evidence-based interventions for DMLs were identified. A small number of interventions examined in high-quality studies of DHH and hearing bilingual learners were identified, which may be appropriate for use with DMLs following further investigation.

Abstract
Purpose Polysyllables, words of 3 or more syllables, represent almost 30% of words used in American English. The purpose of this tutorial is to support speech-language pathologists' (SLPs') assessment and analysis of polysyllables, extending the focus of published assessment tools that focus on sampling and analyzing children's segmental accuracy and/or the presence of phonological error patterns. Method This tutorial will guide SLPs through a review of 53 research papers that have explored the use of polysyllables in assessment, including the sampling and analysis procedures used in different research studies. The tutorial will also introduce two new tools to analyze and interpret polysyllable speech samples: the Word-Level Analysis of Polysyllables (WAP; Masso, 2016b) and the Framework of Polysyllable Maturity (Framework; Masso, 2016a). Results Connected speech and single-word sampling tasks were used across the 53 studies to elicit polysyllables, and a number of analysis methods were reported, including measures of segmental accuracy and measures of structural and suprasegmental accuracy. The WAP and the Framework extend SLPs' depth of analysis of polysyllables. Conclusion SLPs need a range of clinical tools to support the assessment and analysis of polysyllables. A case study comparing different speech analysis methods demonstrates the clinical value in utilizing the WAP and the Framework to interpret children's polysyllable productions in addition to traditional methods of speech sampling and analysis.

Abstract
Background Few studies have analyzed gains in using computers in speech and language therapy interventions for children with speech and/or language disorders when compared to a control group, but virtual tutors and computer-based visual feedback have been gaining interest in the literature. Previous systematic reviews mainly focused on development technological details of computer-based speech training systems or the potential of integrating mobile technology into education and rehabilitation, but recent systematic reviews have also evaluated the efficacy of computer-based speech and language therapy for children and how digital technology can support different activities, at school or elsewhere. Objective This study aimed to analyze a continuous communication and joint team approach to develop solutions focused on the real needs of end users, which digitally emulate reliable and validated physical intervention materials for children with speech sound disorders (SSD). Methods The Table to Tablet (T2T) software was developed using a design-based research methodology, which included four phases: activities development; ethnographic pretesting with a sample from the target population; software development; and beta-testing. The technology used to develop the software, the method used to ensure satisfaction and replay ability of the intervention materials, and results from the ethnographic and beta-testing phases are presented. Results Nineteen activities were developed during the first phase, which were then tested, with 7 service users, using a physical prototype. The beta-test approach included extensive testing and reformulation, supported by direct, nonparticipant observation and data collection using a questionnaire designed for children. Feedback was used to improve the software and interaction with users. Conclusions The use of T2T-based intervention programmes by speech and language therapists (SLTs) will allow these professionals to make a better and more effective communication intervention, based on proven methodologies, that coexists in a structured physical and a digital version. These versions provide a full, 6-week intervention program, with minimal effort in preparing the session by the SLTs while delivering a very consistent intervention, with high replay value. A continuous communication and joint team approach was beneficial to the project and to the development of a solution focused on the real needs of SLTs and children with SSD. All problems were approached as a team with different skills and expertise, which minimized errors (eg, the developer making choices that would save him from spending time doing something that would not be used) and time spent. To add to this, the importance of integrating the end users as testers and collecting their opinions and actions per session allowed the production of better-targeted activities.

Abstract
Purpose
Diagnostic decision making is influenced by the attributes of assessments. In order to propose time-efficient protocols for screening children's speech, this study aimed to determine whether eliciting imitated responses and analyzing productions in different word positions resulted in different levels of consonant accuracy.
Method
Participants were 267 English-speaking preschool-age children in the Sound Start Study whose parents were concerned about their speech. They were assessed using the International Speech Screener: Research Version (ISS;
McLeod, 2013
) using either imitated or spontaneous elicitation. Productions were compared with an established diagnostic assessment of speech accuracy (Diagnostic Evaluation of Articulation and Phonology;
Dodd, Hua, Crosbie, Holm, & Ozanne, 2002
).
Results
Participants' performance on the ISS was significantly correlated with performance on the Diagnostic Evaluation of Articulation and Phonology. Eliciting imitated productions on the ISS (
M
= 2:18 min,
SD
= 0:59 min) took significantly less time than spontaneous productions (
M
= 6:32 min,
SD
= 2:34 min). There was no significant difference in accuracy of imitated versus spontaneous productions in word-initial position; however, consonants were significantly less accurate in spontaneous than imitated productions in other word positions. Overall, participants had significantly lower consonant accuracy in word-initial position than within-word or word-final positions. Examination of the influence of word position on test discrimination, using receiver operating characteristic analyses, revealed acceptable test discrimination for percentage of consonants correct across word positions.
Conclusion
This research supports using imitated elicitation and analysis of percentage of consonants correct in word-initial position as a time-efficient procedure when screening the speech of English-speaking preschool children.

Abstract
The aim of this research was to explore how preschool-aged children with phonological impairment (PI) realise grammatical morphemes across different phonological contexts (i.e. singleton consonant, consonant cluster, syllable), conditions of finiteness and individual morpheme types. Factors accounting for children's realisation of grammatical morphemes were also examined. Eighty-seven Australian English-speaking preschoolers (aged 4-5 years) with PI completed the Children's Assessment of Morphophonology (CHAMP)-an elicited response task-in addition to standardised tests of speech and receptive language. The most challenging grammatical morphemes were finite morphemes (particularly past tense) and grammatical morphemes realised in consonant clusters. The ability to produce consonant clusters in single words significantly accounted for children's ability to realise grammatical morphemes, regardless of whether grammatical morphemes were realised in singleton, consonant cluster or syllable contexts. Realisation of grammatical morphemes by preschoolers with PI is influenced by phonological and morphological factors. The findings have implications regarding the assessment and differential diagnosis of preschoolers with concomitant phonological and language difficulties.

Abstract
PURPOSE During early childhood, it is important to identify which children require intervention before they face the increased demands of school. This study aimed to: (1) compare parents' and educators' concerns, (2) examine inter-rater reliability between parents' and educators' concerns and (3) determine the group difference between level of concern and children's performance on clinical testing. METHOD Parents and educators of 1205 4- to 5-year-old children in the Sound Start Study completed the Parents' Evaluation of Developmental Status. Children whose parents/educators were concerned about speech and language underwent direct assessment measuring speech accuracy (n = 275), receptive vocabulary (n = 131) and language (n = 274). RESULT More parents/educators were concerned about children's speech and expressive language, than behaviour, social-emotional, school readiness, receptive language, self-help, fine motor and gross motor skills. Parents' and educators' responses were significantly correlated (except gross motor). Parents' and educators' level of concern about expressive speech and language was significantly correlated with speech accuracy on direct assessment. Educators' level of concern was significantly correlated with a screening measure of language. Scores on a test of receptive vocabulary significantly differed between those with concern and those without. CONCLUSION Children's communication skills concerned more parents and educators than other aspects of development and these concerns generally aligned with clinical testing.

Abstract
OBJECTIVES The aim of the present study was to develop an iPad application for computer-aided articulation therapy called the Turkish Articulation Therapy Application (TARTU), and make comparisons between the efficacy of TARTU and printed material. METHOD A single subject research design, adapted alternating treatments model, was used for this purpose. The study was carried out with 2 children, at the age of 5; 1 and 5; 11, both of whom have a speech sound disorder. The comparison between TARTU and printed material effectiveness was compared for three target sounds (/k/, /ʃ/ and /l/). 12 therapy sessions were carried out three times a week using the behavioural approach. One participant received therapy targeting the sound /k/ using TARTU, while printed material used for the sound /ʃ/. The targeted sounds were switched for the second participant. Sound /l/ was left without any intervention. RESULT The target sound met the criterion with TARTU in one participant, and with printed material in the other participant. CONCLUSION The presentation type of the materials did not play an important role in the success of the therapy on the participants.

Setting up a cohort study in speech and language therapy: lessons from The UK Cleft Collective Speech and Language (CC-SL) study. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2018; 53:421-430.

Abstract
BACKGROUND Efforts to increase the evidence base in speech and language therapy are often limited by methodological factors that have restricted the strength of the evidence to the lower levels of the evidence hierarchy. Where higher graded studies, such as randomized controlled trials, have been carried out, it has sometimes been difficult to obtain sufficient power to detect a potential effect of intervention owing to small sample sizes or heterogeneity in the participants. With certain clinical groups such as cleft lip and palate, systematic reviews of intervention studies have shown that there is no robust evidence to support the efficacy of any one intervention protocol over another. AIMS To describe the setting up of an observational clinical cohort study and to present this as an alternative design for answering research questions relating to prevalence, risk factors and outcomes from intervention. METHODS The Cleft Collective Speech and Language (CC-SL) study is a national cohort study of children born with cleft palate. Working in partnership with regional clinical cleft centres, a sample size of over 600 children and 600 parents is being recruited and followed up from birth to age 5 years. Variables being collected include demographic, psychological, surgical, hearing, and speech and language data. MAIN CONTRIBUTION The process of setting up the study has led to the creation of a unique, large-scale data set which is available for researchers to access now and in future. As well as exploring predictive factors, the data can be used to explore the impact of interventions in relation to individual differences. Findings from these investigations can be used to provide information on sample criteria and definitions of intervention and dosage which can be used in future trials. CONCLUSIONS The observational cohort study is a useful alternative design to explore questions around prevalence, risk factors and intervention for clinical groups where robust research data are not yet available. Findings from such a study can be used to guide service-delivery decisions and to determine power for future clinical trials.

JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2017; 60:1877-1890. [PMID: 28658484 DOI: 10.1044/2017_jslhr-s-16-0171] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2016] [Accepted: 02/13/2017] [Indexed: 06/07/2023]
Abstract
PURPOSE The aim of this study was to determine if polysyllable accuracy in preschoolers with speech sound disorders (SSD) was related to known predictors of later literacy development: phonological processing, receptive vocabulary, and print knowledge. Polysyllables-words of three or more syllables-are important to consider because unlike monosyllables, polysyllables have been associated with phonological processing and literacy difficulties in school-aged children. They therefore have the potential to help identify preschoolers most at risk of future literacy difficulties. METHOD Participants were 93 preschool children with SSD from the Sound Start Study. Participants completed the Polysyllable Preschool Test (Baker, 2013) as well as phonological processing, receptive vocabulary, and print knowledge tasks. RESULTS Cluster analysis was completed, and 2 clusters were identified: low polysyllable accuracy and moderate polysyllable accuracy. The clusters were significantly different based on 2 measures of phonological awareness and measures of receptive vocabulary, rapid naming, and digit span. The clusters were not significantly different on sound matching accuracy or letter, sound, or print concept knowledge. CONCLUSIONS The participants' poor performance on print knowledge tasks suggested that as a group, they were at risk of literacy difficulties but that there was a cluster of participants at greater risk-those with both low polysyllable accuracy and poor phonological processing.
