[Early indicators of childhood apraxia of speech in late talkers: general guidelines to intervention]. / Indicadores tempranos de dispraxia verbal en el inicio tardío: orientaciones para la intervención Inmaculada.

INTRODUCTION: The population of children with slow emergence of language development varies widely, both in their initial profile and in their response to intervention. In this sense, there is a group of late talkers who continue to show persistent language difficulties, in some cases exhibiting signs compatible with verbal dyspraxia. METHOD: In this paper we present the different response to intervention of two profiles of late talkers. Specifically, the Target Word© program (Hanen Centre) was implemented, which is addressed to latetalking children and their families. It combines the technique of focused stimulation with guidance to parents on strategies that stimulate global language development. RESULTS: Much of the symptomatology shown in one case of poor progress coincides with retrospective descriptions of children subsequently diagnosed with dyspraxia and can be considered early indicators of the disorder: unintelligibility, reduced consonant inventory or difficulties in word repetition. DISCUSSION: The different response to intervention contributes to diagnostic decision making and the early implementation of specific strategies directed to improve speech learning skills by incorporating motor learning principles. The few studies of intervention in suspected verbal dyspraxia in early childhood offer promising results on a variety of speech assessment indicators, and provide practitioners with valuable information with which to support the intervention in this population.

Introducción: La población de niños que comienzan con lentitud el desarrollo del lenguaje varía ampliamente, tanto en su perfil inicial como en la respuesta a la intervención. En este sentido, existe un grupo de niños, denominados hablantes tardíos, que continúan mostrando dificultades persistentes en el lenguaje. Algunos de estos niños muestran signos compatibles con la dispraxia verbal, y que se ponen de manifiesto a lo largo de la intervención. Método: En este trabajo presentamos la diferente respuesta a la intervención de dos perfiles de hablante tardío. Concretamente, se aplicó el programa Target Word©, del centro Hanen, que conjuga la técnica de la estimulación focalizada con la orientación a padres sobre estrategias que promueven el desarrollo del lenguaje. Resultados: Gran parte de la sintomatología mostrada en uno de los dos casos, que experimentó un progreso pobre, coincide con las descripciones retrospectivas de niños posteriormente diagnosticados con dispraxia y pueden considerarse indicadores tempranos del trastorno: ininteligibilidad, inventario consonántico reducido o dificultades en la repetición de palabras. Discusión: La diferente respuesta a la intervención contribuye a la toma de decisiones diagnósticas y a la aplicación temprana de estrategias específicas para la mejora de las habilidades de aprendizaje del habla mediante la incorporación de los principios del aprendizaje motor. Los escasos estudios de intervención en casos de sospecha de dispraxia verbal en la infancia temprana ofrecen resultados prometedores en diversos indicadores de evaluación del habla, y proporcionan a los profesionales una información valiosa en la que fundamentar la intervención en esta población.

Varying Syntax to Enhance Verb-Focused Intervention for 30-Month-Olds With Language Delay: A Concurrent Multiple Baseline Design.

PURPOSE: The purpose of this study is to determine if 2.5-year-olds with language delay would learn verbs (spill) when presented with varying syntactic structure ("The woman is spilling the milk"/"The milk is spilling"; milk = patient or theme) in a therapeutic context. Children with language delay have proportionally small inventories of verbs, which limits expressive language development. Children who have typical language development learn verbs more robustly when presented with alternating arguments than with a single argument structure. METHOD: Three toddlers with expressive language delay (29-30 months of age) participated in a verb-focused treatment study using a concurrent multiple baseline design. Participants were shown action videos accompanied by sentences with varied argument structure for each target verb. To assess learning pre- and posttreatment, participants were asked to demonstrate actions corresponding to each verb. RESULTS: Visual inspection and tau analyses reveal significant posttreatment gains of target verbs taught with varying argument structures. CONCLUSIONS: Our results indicate that learning verbs with high variability of argument roles may facilitate a strong link between lexical representations of verbs and their syntactic structures. Using argument structure variability to teach verbs as an intervention strategy has great potential and should be tested further in larger group studies.

Naturalistic Developmental Behavioral Interventions for Developmental Language Disorder.

PURPOSE: Naturalistic-developmental-behavioral interventions (NDBIs) are a widely accepted and validated approach for treating language-related symptoms in autism spectrum disorder, including deficits in vocabulary, social skills, and grammar. The purpose of this article is to define the elements naturalistic, developmental, and behavioral as applied to children with developmental language disorder (DLD) and to provide an example of how this type of intervention can be implemented to teach vocabulary and test cross-modal generalization between expressive and receptive modalities. METHOD: A vocabulary intervention using hybrid NDBI methods (storybook reading and conversational recast interaction) was provided to three participants with DLD using a single-case design. RESULTS: The results indicated that all participants successfully learned receptive and expressive vocabulary targets with extensive cross-modal generalization. However, generalization was limited in some of the participants. CONCLUSIONS: This article provided definitions of key elements of NDBI (naturalistic, developmental, and behavioral) including a rationale for extending NDBI procedures to language intervention for children with DLD. In addition, a single-case design demonstrated that NDBI can be implemented in DLD and that broadly defined naturalistic-developmental applied behavior analysis techniques are applicable to language interventions for children with language disorders. Moreover, diverse naturalistic and developmental procedures meet the highest standards for evidence-based practice to treat DLD.

Knowledge and Perspectives of Developmental Language Disorders: The Pilot Development of a Survey of Professionals Working in Law Enforcement.

PURPOSE: The purpose of this study was to pilot test a survey of professionals within the justice system about their knowledge and perceptions of developmental language disorders (DLDs) and to gather initial data supporting their knowledge and perceptions. METHOD: One hundred thirty-six adults in Texas with law enforcement jobs, primarily police officers, participated in this study. Participants completed a survey consisting of 78 questions about their background, experiences with DLD, and beliefs about communication. Additionally, 42 adults who did not work in law enforcement completed the survey twice to establish the initial measures of survey reliability. RESULTS: This survey demonstrated sufficient test-retest reliability with adults not in law enforcement, and results indicated the emergence of two subscales within the survey. Law enforcement professionals appeared to have limited knowledge of DLD, and many linked language-related behaviors with credibility. A majority did agree with giving accommodations to individuals who struggle with language and reported interest in receiving training to recognize and accommodate DLD. CONCLUSIONS: This pilot study demonstrates a need for collaboration between speech-language pathologists and law enforcement professionals and provides data for a survey that could be used across professional groups in the justice system to measure knowledge and perspectives of DLDs. This work represents an initial step in an iterative process of survey development for law enforcement professionals. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.25033718.

Replication of a single-case design cross-situational statistically based word learning treatment for late talking children.

PURPOSE: Late talking children are at risk of ongoing language impairment. This intervention study replicated and extended research based on cross-situational statistical learning principles. METHOD: Three late talking children (age 24-32 months) were enrolled into the concurrent multiple baseline single-case experimental intervention study. The intervention consisted of 16 sessions over eight/nine weeks, including 10-11 pairs of target and control words (three per session). Children heard the target words a minimum of 64 times per session, in sentences with high linguistic variability in varied play activities. RESULT: All children increased production of target words and expressive vocabulary, with statistically significant differences between word acquisition in baseline and intervention phases. One of the three children learnt statistically significantly more target words than control words. CONCLUSION: The results replicated the findings of previous research for some but not all of the participants, providing individual evidence that this approach has promise as a therapy technique for late talking children.

Collaborative working in speech and language therapy for children with DLD-What are parents' needs?

BACKGROUND: Collaborative practice between therapists and parents is a key element of family-centred care and is essential if we want to address family priorities and needs in interventions. However, collaborative practice is challenging for speech and language therapists (SLTs) and parents. To facilitate collaboration, collaborative practices need to be implemented into speech and language therapy for young children with developmental language disorders (DLD) and their families. Actual change and implementation of collaboration in practice will be successful only when it corresponds with patients' needs, in our case the needs of parents of young children with DLD. AIMS: To explore parents' needs in their collaboration with SLTs during therapy for their young child with DLD. METHODS & PROCEDURES: Parents of children with (a risk of) DLD in the age of 2-6 years were eligible for participation. We recruited parents via SLTs. Twelve parents of children with DLD participated in semi-structured interviews about their needs in collaboration with SLTs. We used a phenomenological approach focusing on parents' lived experiences. We transcribed the interviews verbatim. All interviews were read/listened to and discussed by our parent panel, multiple researchers and the interviewer. Two researchers independently analysed the data using the reflective thematic analysis of Braun and Clarke. OUTCOMES & RESULTS: The analysis of the interviews resulted in six themes: (1) knowing what to expect, (2) knowing how to contribute, (3) feeling capable of supporting the child, (4) trusting the therapist, (5) alignment with parents and children's needs, preferences and priorities and (6) time and space for asking questions and sharing information. CONCLUSIONS & IMPLICATIONS: Parents want SLTs to invest time in collaborating with them. Parents need SLTs to empower them to become a collaborative partner and enable them to support their child in daily life. Parents need knowledge about the therapy process and diagnosis and skills in how to support their child's language development. Also, they need emotional support to feel secure enough to support their child, to ask questions to therapists and to bring up their own thoughts and opinions in therapy. Parents' needs are in line with collaborative working as described in literature, which underlines the importance of implementing collaborative working in speech and language therapy for young children with DLD. WHAT THIS PAPER ADDS: What is already known on the subject Several reviews have explored parents' perspectives on speech and language therapy. Results reveal parents' experiences with speech and language therapy in general, and parents' perspectives on specific topics such as shared decision-making and parents/therapists roles in therapy. What this study adds This study adds insights into parents' needs to ensure collaboration with speech and language therapists (SLTs). Parents of young children with developmental language disorders (DLD) need SLTs to invest time to create optimal collaboration. It is important for parents to have enough knowledge about DLD and the SLT process, skills and confidence in how to support their child and opportunities to share thoughts and questions with SLTs. Our results underline the importance of parents being empowered by SLTs to become a collaborative partner. What are the clinical implications of this work? When children are referred to speech and language therapy, parents often venture into an unknown journey. They need support from SLTs to become a collaborative partner in speech and language therapy. Parents need SLTs to invest time in sharing knowledge, skills and power and align therapy to parents' and child's needs, preferences, priorities and expectations.

Preparing Student Clinicians to Provide Recast Therapy on Complement Clauses: A Training Program.

PURPOSE: This study reports on a program to train student clinicians to provide recast therapy on complement clauses to children with developmental language disorder (DLD). To determine the efficacy of the program, we conducted secondary data analysis based on Owen Van Horne et al. (2023) and examined student clinicians' recasts after training and children's progress after treatment. METHOD: Three student clinicians received a two-stage training, followed by a real intervention program targeting complement clauses in six children with DLD. A third of the intervention sessions were coded for the total number and number of unique verbs in complement clauses provided by the student clinicians. An elicited production task was completed to test children's knowledge of the target structure. RESULTS: On average, student clinicians provided 30 targeted recasts to each child during each intervention session. They provided a greater number of and more variable input for that compared to WH complements. Children demonstrated significant improvement only in WH, but not in that, complements. CONCLUSIONS: A targeted training program could strengthen clinicians' ability to provide recast therapy on complex syntax; however, future refinements should shorten and broaden training to include more targets. A mismatch between input patterns and learning patterns was observed. WH complement input is more stable than that input, given the less variable complement-taking verbs provided by the student clinicians and the overtness of the WH word as a stable complementizer, which may have facilitated the identification and extraction of the target syntactic structure.

Assessment of Language Development in Dual Language Learners: A Case Report.

Propelled by immigration, language diversity is increasing in the United States, and more young children are exposed to two or more languages at home from birth. Known as dual language learners (DLLs), the benefits of this exposure include multilingual and multiliterate outcomes. However, DLLs introduce complexity for the pediatric provider's assessment of language development, identification of potential language delays, and timely referrals. If language delays are not promptly identified and followed with early intervention, they can persist and lead to poor outcomes across multiple domains.

Strategies for Teaching Verbs to Children with and without Language Impairment.

The aim of this feasibility study was to extend the current evidence base on intransitive verb learning by evaluating and comparing three strategies (syntactic cues, semantic cues, combined cues) for teaching novel verbs to expand the vocabularies of children with and without language impairment. Twenty-three children with typical development, seven children with developmental language disorder, and eight children with Down syndrome participated in Studies 1, 2, and 3, respectively. They were taught novel, intransitive verbs using syntactic, semantic, and combined cues and then asked to receptively identify and expressively label the novel verbs. Across all conditions, participants learned novel verbs receptively with large effect sizes and participants with typical development and Down syndrome also learned the verbs expressively with large effect sizes. There were no significant differences between conditions. This study extends word-learning research by evaluating not only receptive but also expressive intransitive verb learning to expand one's vocabulary. The results provide positive evidence for three effective strategies for teaching intransitive verbs to children with and without language impairment.

Speech-Language Pathologists' Perceptions of Language and Literacy Instruction for Pre-K Children With Developmental Language Disorder.

PURPOSE: Speech-language pathologists (SLPs) have multiple roles and responsibilities related to language and literacy instruction in schools. The purpose of this exploratory, qualitative study was to analyze school-based SLPs' perceptions related to effective language and early literacy instruction for pre-K children with developmental language disorder (DLD). The goal of this study was to inform development of a new language and early literacy professional development program for inclusive pre-K teachers. METHOD: Eight school-based SLPs participated in a 1-hr virtual focus group conducted via Zoom recording technology. The researchers used a conventional content analysis approach to analyze the focus group data and identify themes from the discussion. RESULTS: The researchers developed two themes: (a) SLPs identified repeated exposure to books, peer interaction, and teaching vocabulary with visual supports and props as key elements of language and literacy instruction that can be integrated into a variety of contexts, and (b) SLPs want more time with parents and teachers to support their book reading and model specific language strategies. CONCLUSIONS: SLPs identified several instructional practices inclusive pre-K teachers could be taught to use during professional development programs to support the emergent literacy development of children with DLD. They also discussed the need for ongoing collaboration between SLPs, caregivers, and teachers to maximize children's early language and literacy experiences. Future research should explore the impact of partnerships with caregivers and teachers on children's language and literacy outcomes.

Review of intervention methods for language and communication disorders in children with autism spectrum disorders.

In recent years, the number of patients-particularly children-with autism spectrum disorder (ASD) has been continually increasing. ASD affects a child's language communication and social interaction to a certain extent and has an impact on behavior, intelligence level, and other aspects of the child. Data indicates that 40% to 70% of children with ASD experience language developmental delays, which are mainly manifested as lack of language or language developmental delay, self-talk, use of stereotyped language, parroting, et cetera. A language communication disorder is a major symptom of ASD and is the most common reason for patients to visit a doctor. Therefore, language intervention training and communication skills have been made a cornerstone of autism intervention. However, a literature search has revealed that most studies only examine certain intervention methods or a combination of two or three intervention methods, which cannot be used by therapists or rehabilitation teachers. Therefore, this article summarizes relevant literature on language communication training for ASD children at home and abroad and briefly introduces the characteristics and training methods of language disorders in children with ASD in order to provide some ideas and references for relevant researchers and practitioners.

Adapting Curricula for Children With Language Comprehension Deficits.

PURPOSE: We will describe how a multisite research team adapted a language-focused curriculum to be used in a scale-up project. Specifically, we identified underlying principles to modify a Tier 1 whole-classroom language comprehension-focused curriculum to be used as a Tier 2 small-group curriculum with children identified as at risk for low language comprehension, including children with developmental language disorder (DLD). METHOD: We discuss how researchers used the following five guiding principles to adapt a curriculum for children at risk for low language comprehension, including children with DLD: (a) increased and ongoing professional development, (b) simplification of language input, (c) increased scaffolding, (d) attention to distributed practice, and (e) materials to support diversity and inclusion. RESULTS: We used these guiding principles to modify a popular language-based curriculum used in schools across the country. CONCLUSION: This clinical focus article showcases how guiding principles and frameworks for adaptation, within implementation science, can serve as a guidepost for speech-language pathologists and other educators who are adapting or scaling up a curriculum or intervention that was not designed for their target population.

Recast Therapy for Treating Syntax in Bilingual Children With Developmental Language Disorder: A Feasibility and Early Efficacy Study Examining the Role of Language of Intervention on Outcomes.

PURPOSE: The purpose of this study is to examine the feasibility of the delivery of complex syntax recast therapy via telepractice to Spanish-English bilingual children and provide preliminary evidence of the efficacy of this approach. METHOD: Fifteen bilingual children with developmental language disorders were stratified based on language proficiency and randomized to one of three treatment conditions: Spanish only (n = 5), English only (n = 6), or Spanish + English (n = 4). Using a within-subject design, we hypothesized that we could document treatment efficacy based on change in the treated structure in the absence of change in an untreated comparison structure. All 15 children completed ~16 hr of treatment via telepractice and participated in pre- and posttesting of their production of conditional adverbs (treated structure) and subject relative clauses (untreated structure) carried out by a masked assessor. RESULTS: Analyses included all participants. Treatment fidelity was high, and participant attendance was remarkable, indicating feasibility. Regarding efficacy, recast therapy led to group-level gains on treated syntactic structures that exceeded those observed for the untreated comparison structure. For the 11 children who received therapy in only one language, approximately equal gains were observed in both the treated and untreated languages for conditional adverbials. CONCLUSIONS: Preliminary evidence suggests that for highly overlapping structures like conditional adverbials, recast therapy is effective and leads to change in both of the child's languages. Larger studies are required to understand how language of administration and proficiency may affect outcomes. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.23739996.

Pattern-Based Target Selection for Treatment of Irregular Past Tense: A Single-Case Experimental Design for Children With Developmental Language Disorder.

PURPOSE: Many children with developmental language disorder (DLD) demonstrate difficulty inflecting irregular past tense verbs. We evaluated using phonological-based patterns (i.e., schemas) to select targets for treatment of irregular verb inflection for children with DLD. We hypothesized this approach would result in acquisition of treated verbs, generalization to untreated verbs within the same phonological schema, and increased use of correct irregular verbs in naturalistic contexts. METHOD: Treatment was provided to three 7-year-old participants with DLD in the context of multiple baseline designs across behaviors and participants. Phonological schemas included vowel change, final alveolar, and dual change irregular verbs. Treatment was provided using established therapeutic approaches, including narrative generation, sentence imitation, and naturalistic play activities. Acquisition of treated and untreated targets was assessed at the beginning of sessions, and use of verbs in naturalistic contexts was observed throughout treatment sessions. RESULTS: Positive acquisition effects were noted for two of three participants. Generalization to untreated items occurred within and across treatment sets for two participants, whereas increases in accurate irregular verb production in naturalistic contexts were not observed. CONCLUSIONS: Outcomes demonstrated support for a pattern-based approach to target selection for treatment of irregular past tense verbs. One participant, who demonstrated general difficulty with the probe and treatment tasks, showed no treatment effect, suggesting that the treatment may be effective for some children with DLD. Further research is warranted to determine what factors might have influenced these variable outcomes across participants. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.23671500.

Criteria and Terminology Applied to Language Impairments (CATALISE): A qualitative exploration of dissemination efforts to guide future implementation.

BACKGROUND: Developmental language disorder (DLD) is a condition which affects an individual's ability to use and understand language. Terminological confusion, and the use of non-evidence-based diagnostic criteria has impacted access to services for this population for several decades. Changes in terminology and diagnosis were proposed as part of a UK-based consensus study, Criteria and Terminology Applied to Language Impairments (CATALISE), in 2016 and 2017. Since the publication of the recommendations, there have been active efforts across several English-speaking countries to support uptake of these recommendations into policy and practice. AIMS: The aim of the study was to explore the experiences of individuals who have been leading the dissemination of the CATALISE recommendations since their publication in 2017. The study was undertaken to inform future implementation efforts aimed at facilitating the adoption of the recommendations into policy and practice. METHODS & PROCEDURES: Researchers, practitioners and parents from nine countries were recruited to the study (n = 27). Online focus groups and semi-structured interviews were conducted using topic guides informed by the Consolidated Framework for Implementation Research. Inductive thematic analysis was undertaken. Preliminary findings were member-checked prior to completion of the analysis. OUTCOMES & RESULTS: CATALISE recommendations were described as partially adopted by participants. Dissemination strategies included building a coalition, conducting educational meetings, and developing educational materials. Common barriers to implementation related to the complexity and compatibility of the recommendations, and practitioner confidence. Four themes were identified across the data set to guide future implementation efforts: (a) ride the wave, craft the narrative (b) reach across the divide, be brave (c) create space for multiple voices and, (d) support for speech and language therapistss on the front line. CONCLUSIONS & IMPLICATIONS: Individuals with DLD and their families should be included in future implementation planning. Engaged leadership is essential to address issues of complexity, compatibility, sustainability and practitioner confidence if CATALISE recommendations are to be integrated into service workflow and processes. Implementation science can provide a useful lens to progress future research in this area. WHAT THIS PAPER ADDS: What is already known on this subject Dissemination efforts have been undertaken to facilitate the uptake of recommendations from a UK-based consensus study (CATALISE) in relation to developmental language disorder since publication across several countries. What this study adds to existing knowledge The required changes in diagnostic practice are complex to implement. A lack of compatibility with healthcare processes and low practitioner self-efficacy were also identified as a challenge to implementation. What are the potential or actual clinical observations of this work? Parents and individuals with developmental language disorder need to be engaged as partners in future implementation planning. Organisational leaders need to facilitate the contextual integration of the changes within service systems. Speech and language therapists require ongoing case-based opportunities to enhance their confidence and clinical reasoning skills to implement CATALISE recommendations successfully in their everyday practice.

Shared characteristics of intervention techniques for oral vocabulary and speech comprehensibility in preschool children with co-occurring features of developmental language disorder and a phonological speech sound disorder: protocol for a systematic review with narrative synthesis.

INTRODUCTION: Evidence suggests that over one-third of young children with developmental language disorder (DLD) or speech sound disorder (SSD) have co-occurring features of both. A co-occurring DLD and SSD profile is associated with negative long-term outcomes relating to communication, literacy and emotional well-being. However, the best treatment approach for young children with this profile is not understood. The aim of the proposed review is to identify intervention techniques for both DLD and SSD, along with their shared characteristics. The findings will then be analysed in the context of relevant theory. This will inform the content for a new or adapted intervention for these children. METHODS AND ANALYSIS: This search will build on a previous systematic review by Roulstone et al (2015) but with a specific focus on oral vocabulary (DLD outcome) and speech comprehensibility (SSD outcome). These outcomes were identified by parents and speech and language therapists within the prestudy stakeholder engagement work. The following databases will be searched for articles from January 2012 onwards: Ovid Emcare, MEDLINE Complete, CINAHL, APA PsycINFO, Communication Source and ERIC. Two reviewers will independently perform the title/abstract screening and the full-text screening with the exclusion criteria document being revised in an iterative process. Articles written in languages other than English will be excluded. Data will be extracted regarding key participant and intervention criteria, including technique dosage and delivery details. This information will then be pooled into a structured narrative synthesis. ETHICS AND DISSEMINATION: Ethical approval is not needed for a systematic review protocol. Dissemination of findings will be through peer-reviewed publications, social media, and project steering group networks. PROSPERO REGISTRATION NUMBER: CRD4202237393.

Teaching little kids big sentences: A randomized controlled trial showing that children with DLD respond to complex syntax intervention embedded within the context of preschool/kindergarten science instruction.

BACKGROUND: The language of the science curriculum is complex, even in the early grades. To communicate their scientific observations, children must produce complex syntax, particularly complement clauses (e.g., I think it will float; We noticed that it vibrates). Complex syntax is often challenging for children with developmental language disorder (DLD), and thus their learning and communication of science may be compromised. AIMS: We asked whether recast therapy delivered in the context of a science curriculum led to gains in complement clause use and scientific content knowledge. To understand the efficacy of recast therapy, we compared changes in science and language knowledge in children who received treatment for complement clauses embedded in a first-grade science curriculum to two active control conditions (vocabulary + science, phonological awareness + science). METHODS & PROCEDURES: This 2-year single-site three-arm parallel randomized controlled trial was conducted in Delaware, USA. Children with DLD, not yet in first grade and with low accuracy on complement clauses, were eligible. Thirty-three 4-7-year-old children participated in the summers of 2018 and 2019 (2020 was cancelled due to COVID-19). We assigned participants to arms using 1:1:1 pseudo-random allocation (avoiding placing siblings together). The intervention consisted of 39 small-group sessions of recast therapy, robust vocabulary instruction or phonological awareness intervention during eight science units over 4 weeks, followed by two science units (1 week) taught without language intervention. Pre-/post-measures were collected 3 weeks before and after camp by unmasked assessors. OUTCOMES & RESULTS: Primary outcome measures were accuracy on a 20-item probe of complement clause production and performance on ten 10-item unit tests (eight science + language, two science only). Complete data were available for 31 children (10 grammar, 21 active control); two others were lost to follow-up. Both groups made similar gains on science unit tests for science + language content (pre versus post, d = 2.9, p < 0.0001; group, p = 0.24). The grammar group performed significantly better at post-test than the active control group (d = 2.5, p = 0.049) on complement clause probes and marginally better on science-only unit tests (d = 2.5, p = 0.051). CONCLUSIONS & IMPLICATIONS: Children with DLD can benefit from language intervention embedded in curricular content and learn both language and science targets taught simultaneously. Tentative findings suggest that treatment for grammar targets may improve academic outcomes. WHAT THIS PAPER ADDS: What is already known on the subject We know that recast therapy focused on morphology is effective but very time consuming. Treatment for complex syntax in young children has preliminary efficacy data available. Prior research provides mixed evidence as to children's ability to learn language targets in conjunction with other information. What this study adds This study provides additional data supporting the efficacy of intensive complex syntax recast therapy for children ages 4-7 with Developmental Language Disorder. It also provides data that children can learn language targets and science curricular content simultaneously. What are the clinical implications of this work? As SLPs, we have to talk about something to deliver language therapy; we should consider talking about curricular content. Recast therapy focused on syntactic frames is effective with young children.

Spoken language outcomes in limited language preschoolers with autism and global developmental delay: RCT of early intervention approaches.

Preschool autistic children with significant global developmental delays and very limited language skills are at high risk for remaining minimally verbal at entry into primary school. This study compared two early intervention models for improving social communication and spoken language outcomes in 164 children who received intervention in their community preschool program for 6 months, with a six-month follow-up. The primary outcome measure was a standardized language assessment, and secondary measures focused on social communication. Results indicated children on average made 6 months gain in language development in the active 6 months of intervention with no difference between intervention models. Children who initiated joint attention more frequently, or who had higher receptive language at baseline made more progress if assigned to receive JASPER, a naturalistic developmental behavioral intervention. Children who received Discrete Trial Training made greater spoken language progress from exit to follow-up. These findings suggest that progress can be made in autistic children who have very little spoken language and who receive targeted early interventions. Individual trajectories vary and depend in part on initial abilities in social communication and receptive language. Future research might consider methods to systematically personalize approaches to fit child characteristics and family preference. LAY SUMMARY: This study compared two different early intervention approaches for teaching spoken language to minimally verbal, globally delayed autistic preschoolers. Children were given an hour of therapy daily for 6 months and then reassessed 6 months later. The majority of the 164 participants were from historically excluded populations (low income and minority), and therapy was delivered in school community settings by expert clinicians. Results indicated that the participants made significant progress regardless of intervention approach: 6 months gain in standardized language scores over 6 months, but slower progress during the period after therapy ended. Children who initiated joint attention more frequently, or who had higher language understanding at baseline made more progress if assigned to receive JASPER, a naturalistic developmental behavioral intervention. Children who received Discrete Trial Training made greater language progress during 6-month period after therapy ended. These findings suggest that progress can be made in children with ASD who have very little spoken language and who receive targeted early interventions.

Effects in language development of young children with language delay during early intervention.

INTRODUCTION: In the Netherlands, early language intervention is offered to young children with Language Delay (LD). The intervention combines groupwise language intervention, individual speech and language therapy and parent-implemented language intervention. This study tests the hypothesis that children with LD show progress in their receptive and expressive language during intervention. Differences in language progress between age groups (< 36 months and ≥ 36 months at intervention start) were expected in favour of the younger group, which might be due to an earlier intervention start, a longer treatment duration or the potential presence of late talkers. METHODS: The study included 183 children with LD (45 children < 3 years of age at intervention start; mean age 32 months, 138 children ≥ 3 years; mean age 40 months). Receptive and expressive language was assessed with norm-referenced tests at intervention start and ending using Routine Outcome Monitoring. A repeated measures MANOVA was carried out to examine language progress and to compare the age groups on receptive syntax, receptive vocabulary, expressive syntax and expressive vocabulary. The Reliable Change Index was used to study individual progress. RESULTS: On average, children in both age groups showed significant improvement in all four language domains. The younger children showed more language progress than the older children in all four domains. When examining individual progress, most of the children displayed reliable improvement for expressive vocabulary. Most children developed in the same pace as their typically developing peers for receptive syntax, receptive vocabulary, and expressive syntax. CONCLUSIONS: Children stabilized or even improved language proficiency during the intervention, indicating that the language gap between these children and typically developing children did not widen further. Younger children displayed more language progress than older children in all four domains, but it is unclear what might explain this difference.
