Syntactic Growth of Adolescent Boys With Fragile X Syndrome or Down Syndrome: A Longitudinal Study.

Purpose: The current study addresses a gap in the literature regarding syntactic development of adolescent boys with fragile X syndrome (FXS) and Down syndrome (DS). Specifically, we ask whether syntactic skills plateau or continue to change during adolescence for these groups and whether the profile of syntactic change differs between boys with FXS and those with DS.

Method: Participants were 38 boys with FXS (with and without autism) and 20 boys with DS between the ages of 10 and 16 years, as well as 33 boys who were neurotypical between the ages of 3 and 8 years at study entry.

A Tutorial for Enhancing Clarity and Transparency in Speech-Language-Hearing Sciences Intervention Research With the TIDieR.

Purpose: The speech-language-hearing sciences (SLHS) field relies on rigorous research to inform clinical practice and improve outcomes for individuals with communication, swallowing, and hearing needs. However, a significant challenge in our field is the lack of accessibility, transparency, and reproducibility of this research. Such insufficiencies limit the generalizability and impact of study findings, particularly intervention research, as it becomes difficult to replicate and use the interventions in both clinical practice and research.

Outcome trajectory estimation for optimal dynamic treatment regimes with repeated measures.

In recent sequential multiple assignment randomized trials, outcomes were assessed multiple times to evaluate longer-term impacts of the dynamic treatment regimes (DTRs). Q-learning requires a scalar response to identify the optimal DTR. Inverse probability weighting may be used to estimate the optimal outcome trajectory, but it is inefficient, susceptible to model mis-specification, and unable to characterize how treatment effects manifest over time.

Comprehension of indirect answers: Developmental trajectory for preschool- and early elementary school-aged children with typical development.

Indirect answers are a common type of non-literal language that do not provide an explicit "yes" or "no" to a question (e.g., "I have to work late" indirectly answered "Are you going to the party?" with a negative response).

Verbs Matter: A Tutorial for Determining Verb Difficulty.

Purpose: Research indicates that when teaching grammatical forms to children, the verbs used to model specific grammatical inflections matter. When learning grammatical forms, children have higher performance when they hear many unique verb forms that vary in their frequency and phonological complexity. In this tutorial, we demonstrate a method for identifying and characterizing a large number of verbs based on their frequency and complexity.

Five Additional Evidence-Based Principles to Facilitate Grammar Development for Children With Developmental Language Disorder.

Purpose: Because the development of grammatical forms is difficult for many children with developmental language disorder (DLD), language interventions often focus on supporting children's use of grammatical language. This article proposes five additional principles to those suggested by Fey et al. (2003) to facilitate the development of grammatical forms by children with DLD.

Virtual Post-Intervention Speech and Language Assessment of Toddler and Preschool Participants in Babble Boot Camp.

Purpose: Babble Boot Camp (BBC) is a parent-implemented telepractice intervention for infants at risk for speech and language disorders. BBC uses a teach-model-coach-review approach, delivered through weekly 15-min virtual meetings with a speech-language pathologist. We discuss accommodations needed for successful virtual follow-up test administration and preliminary assessment outcomes for children with classic galactosemia (CG) and controls at age 2.

Precision Medicine as a New Frontier in Speech-Language Pathology: How Applying Insights From Behavior Genomics Can Improve Outcomes in Communication Disorders.

Purpose: Precision medicine is an emerging intervention paradigm that leverages knowledge of risk factors such as genotypes, lifestyle, and environment toward proactive and personalized interventions. Regarding genetic risk factors, examples of interventions informed by the field of medical genomics are pharmacological interventions tailored to an individual's genotype and anticipatory guidance for children whose hearing impairment is predicted to be progressive. Here, we show how principles of precision medicine and insights from behavior genomics have relevance for novel management strategies of behaviorally expressed disorders, especially disorders of spoken language.

Developmental Language Disorder Terminology: A Survey of Speech-Language Pathologists' Use and Knowledge.

Purpose: Developmental language disorder (DLD) is a relatively new, internationally promoted term to describe individuals with language impairments not secondary to a biomedical condition. This study aimed to better understand speech-language pathologists' (SLPs') current level of comfort using DLD terminology and knowledge of DLD in the United States to help SLPs better understand how and why they should consider adopting DLD terminology in their clinical practice.

Method: After completing an online presurvey to evaluate current comfort levels in using DLD terminology and current knowledge of DLD, currently practicing SLPs viewed a 45-min prerecorded educational video on DLD.

Consistency and reliability of automated language measures across expressive language samples in autism.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder with substantial clinical heterogeneity, especially in language and communication ability. There is a need for validated language outcome measures that show sensitivity to true change for this population. We used Natural Language Processing to analyze expressive language transcripts of 64 highly-verbal children and young adults (age: 6-23 years, mean 12.

Feasibility of a Proactive Parent-Implemented Communication Intervention Delivered via Telepractice for Children With Classic Galactosemia.

Purpose: This study evaluated the feasibility of Babble Boot Camp (BBC) for use with infants with classic galactosemia (CG) starting at less than 6 months of age. BBC is a parent-implemented intervention delivered by speech-language pathologists (SLPs) entirely via telepractice with the potential to increase access to early preventative interventions. We evaluated BBC feasibility based on acceptability, implementation, and practicality.

Caregiver-Implemented Communication Interventions for Children Identified as Having Language Impairment 0 Through 48 Months of Age: A Scoping Review.

Purpose: Caregiver-implemented interventions are frequently used to support the early communication of young children with language impairment. Although there are numerous studies and meta-analyses supporting their use, there is a need to better understand the intervention approaches and identify potential gaps in the research base. With that premise, we conducted a scoping review to synthesize existing data with an end goal of informing future research directions.

Toward Preventing Speech and Language Disorders of Known Genetic Origin: First Post-Intervention Results of Babble Boot Camp in Children With Classic Galactosemia.

Purpose Babble Boot Camp (BBC) is a package of proactive activities and routines designed to prevent speech and language disorders in infants at predictable risk. It is implemented via parent training and currently undergoing clinical trial in children with a newborn diagnosis of classic galactosemia (CG), a metabolic disease with high risk of speech and language disorders. The purpose of this study is to provide updates to a previous pilot study and to present the first set of post-intervention results.

Parent education to improve early language development: A preliminary evaluation of LENA Start.

Parents play an important role in creating home language environments that promote language development. A nonequivalent group design was used to evaluate the effectiveness of a community-based implementation of LENA Start™, a parent-training program aimed at increasing the quantity of adult words (AWC) and conversational turns (CT). Parent-child dyads participated in LENA Start™ (n = 39) or a generic parent education program (n = 17).

Using Computerized Language Analysis to Evaluate Grammatical Skills.

Purpose Conducting in-depth grammatical analyses based on language samples can be time consuming. Developmental Sentence Scoring (DSS) and the Index of Productive Syntax (IPSyn) analyses provide detailed information regarding the grammatical profiles of children and can be conducted using free computer-based software. Here, we provide a tutorial to support clinicians' use of computer-based analyses to aid diagnosis and develop and monitor treatment goals.

Comparing Morphosyntactic Profiles of Children With Developmental Language Disorder or Language Disorder Associated With Autism Spectrum Disorder.

Purpose Previous cross-population comparisons suggest a considerable overlap in the morphosyntactic profiles of children with developmental language disorder (DLD) and children who experience language disorder associated with autism spectrum disorder (LD-ASD). The goal of this study was to further examine and compare the morphosyntactic profiles of the two populations using both standardized, norm-referenced assessments and language sample analysis. Method We used the Structured Photographic Expressive Language Test-Third Edition (Dawson et al.

Linguistic Maze Production by Children and Adolescents With Attention-Deficit/Hyperactivity Disorder.

Purpose Previous investigations reveal that children with attention-deficit/hyperactivity disorder (ADHD) produce elevated rates of linguistic mazes (i.e., filled pauses, repetitions, revisions, and/or abandoned utterances) in expressive language samples (Redmond, 2004).

Evaluation of a Combined Explicit-Implicit Approach to Teach Grammatical Forms to Children With Grammatical Weaknesses.

Purpose Many children with developmental disorders experience difficulty mastering grammatical forms, including children with developmental language disorder and a subset of children with autism spectrum disorder (ASD). One of the key language features in both of these populations is a weakness in the expressive use of grammatical forms. There is a paucity of studies that evaluate the effectiveness of interventions targeting grammatical forms for populations other than developmental language disorder.

Requests for Communication Repair Produced by Typically Developing Preschool-Age Children.

Purpose When breakdowns in communication occur, children may request a repair to increase understanding of the message. Unrepaired communication breakdowns may cause confusions, limit conversational exchanges, and restrict children's learning opportunities. Relatively little is known regarding the conditions under which children produce repair requests.

Evaluation of an Explicit Instructional Approach to Teach Grammatical Forms to Children With Low-Symptom Severity Autism Spectrum Disorder.

Purpose Weaknesses in the use of grammatical forms may reduce the functional use of language for verbally expressive children with autism spectrum disorder (ASD) and exacerbate difficulties with academic and social skill development. This early efficacy study evaluated a combined explicit-implicit instructional approach to teach novel grammatical forms to children with ASD. Method Seventeen children with ASD between the ages of 4 and 10 years who demonstrated weaknesses in expressive grammatical language completed 2 tasks, each targeting a different novel grammatical form.

Toward a paradigm shift from deficit-based to proactive speech and language treatment: Randomized pilot trial of the Babble Boot Camp in infants with classic galactosemia.

Speech and language therapy is typically initiated reactively after a child shows delays. Infants with classic galactosemia (CG), a metabolic disease with a known high risk for both speech and language disorders, hold the keys towards evaluating whether preventive treatment is effective when the risks are known at birth. We present pilot data from a randomized parallel trial of an innovative proactive speech and language intervention program, the Babble Boot Camp (BBC).

Current Practice of Child Grammar Intervention: A Survey of Speech-Language Pathologists.

Purpose: The aim of this study was to better understand current grammatical intervention approaches. Despite grammatical language being a common weakness among children with language impairment, relatively little is known about current grammatical intervention practices of speech-language pathologists (SLPs). Such information is needed to guide the development and evaluation of grammatical interventions and to identify areas in which the current practice is not empirically supported.

Evaluation of an Explicit Intervention to Teach Novel Grammatical Forms to Children With Developmental Language Disorder.

Purpose: Unlike traditional implicit approaches used to improve grammatical forms used by children with developmental language disorder, explicit instruction aims to make the learner consciously aware of the underlying language pattern. In this study, we compared the efficacy of an explicit approach to an implicit approach when teaching 3 novel grammatical forms varying in linguistic complexity.

Method: The study included twenty-five 5- to 8-year-old children with developmental language disorder, 13 of whom were randomized to receive an implicit-only (I-O) intervention whereas the remaining 12 participants were randomized to receive a combined explicit-implicit (E-I) intervention to learn 3 novel grammatical forms.

The Evaluation of a Personal Narrative Language Intervention for School-Age Children With Down Syndrome.

The purpose of this study was to evaluate the feasibility of an intervention focused on improving personal narrative skills of school-age children with Down syndrome (DS) using an approach involving visual supports. Four females with DS, ages 10 through 15 years, participated in this multiple baseline across participants single-subject experimental design study. Participants completed 18 intervention sessions that targeted personal narrative goals.
