Purpose: Treatment response is the degree to which an individual benefits from a treatment. This systematic review sought to identify and synthesize research evidence regarding individual characteristics that predict language treatment response among children with developmental language disorder (DLD).

Method: To be eligible for inclusion, articles needed to report results of an oral language treatment program in a group of children aged 4-10 years with identified DLD and also include a quantitative analysis of the relation between one or more pretreatment child characteristics and the outcome of language treatment. Seven databases (Cumulated Index to Nursing and Allied Health Literature, Dissertations and Theses Global, Education Resources Information Center, Linguistics and Language Behavior Abstracts, PsycINFO, Medline, and Web of Science) were searched for articles in June and July 2021, with search updates conducted in May 2023. Studies were categorized by the type of treatment provided, and results were synthesized qualitatively.

Results: The review included 31 studies, 1,551 participants with DLD, and over 300 statistical tests of a predictor's effect on language treatment response. Most studies (n = 21) included only monolingual speakers of English, with five studies including bilinguals and five including monolingual speakers of non-English languages. Language treatments targeted word learning in controlled or clinical conditions, grammatical learning in controlled or clinical conditions, or multiple language targets in clinical conditions. Predictors of treatment response are summarized across four categories: cognitive, demographic, pretreatment language levels, and other.

Conclusions: There were relatively few significant tests of the predictors of language treatment response. A central limitation of the evidence is that most included studies were designed to consider language treatment efficacy, not predictors of treatment response. Increasing research attention to the question of predictors of language treatment response in children with DLD is needed to enhance treatment and optimize outcomes for individual children.

Purpose: Technology-enabled care, including the use of mobile health (mHealth), is emerging as a viable hearing health care delivery method. While the integration of mHealth with adult populations currently supports a wide array of hearing services, a better understanding of the implementation across the lifespan is needed. Literature surrounding the unique population of adolescent hearing aid users is currently lacking. Research is needed to highlight factors important to the use and clinical integration of mHealth hearing aid applications (apps) with adolescents. This study explored two primary objectives: (a) audiologists' perceptions around the use of mHealth apps to enable collaborative, child-inclusive hearing aid personalization, and (b) person-centered ideation around potential app design components to benefit users aged 12 to 17 years.

Method: Twelve audiologists participated in virtual synchronous focus groups, across three group sessions using Cisco Webex. Sessions were recorded, transcribed, and analyzed using an inductive, codebook thematic analysis approach.

Results: Six main themes resulted from group discussion analyses: (a) client candidacy: characteristics impacting suitability for mHealth use; (b) clinical implementation: organizational, professional, or patient-level strategies for mHealth adoption; (c) collaboration: the use of two or more individuals working together; (d) empowerment: process of acquiring and using knowledge, skills, and strategies; (e) remote technology: technologies enabling remote hearing aid personalization; and (f) application functionality and design: features and characteristics important to an adolescent-focused app.

Conclusions: Findings identified the potential for clinical integration of hearing aid apps with adolescents in a collaborative care model, including consideration of child-specific use patterns, outcomes, and key design and technology components to support real-world implementation and use. Results may guide development and tailoring efforts around existing and future hearing aid apps for use with adolescent populations.

Purpose: Gesture delay in autistic infants and toddlers has been widely reported. The developmental trajectory of gesture production during early childhood is understudied. Thus, little is known about the possible changes of gesture production over time. The present study aimed to document the development of gesture production in autistic children and examine whether child-based factors (chronological age and initial language skills) predicted gesture development.

Method: A total of 33 Chinese-speaking autistic children (M_age = 56.39 months, SD = 8.54 months) played with their parents at four time points over a 9-month period. Their speech was transcribed, and their gestures were coded from parent-child interaction. Multilevel modeling analysis was used to investigate the development of gesture and its associated factors.

Results: The total number of gestures produced by autistic children decreased over time. Among different factors, children's initial age significantly and negatively predicted children's gesture production, while initial language positively predicted children's gesture production.

Conclusions: Gesture delay persists in preschool age. The decline in gesture production was associated with children's age and initial language ability. These findings shed light on the difficulties surrounding gesture use in autistic children.

Purpose: This article describes DigiSpan, a new computer-controlled auditory test of forward and reverse digit span, designed to be administered by clinicians, and presents normative and test-retest reliability data for adults.

Method: DigiSpan mimics conventional live-voice tests in that it commences with trials that ascend in length until a stopping criterion is met, giving rise to a conventional scaled score. It then administers five additional adaptive trials, the length of which depends on the correctness of the response to the previous trial. Each of these two segments of the measurement gives rise to a scaled score. The ascending and adaptive scores are averaged to give an overall score and subtracted to produce an internal measure of consistency, and hence reliability. Young adults with an M_age of 25 years (N = 163) were tested, of whom 65 were retested on a separate day.

Results: The scaled scores from the conventional ascending trials were highly consistent with existing normative data based on live-voice tests. Combination of the conventional scaled score with a scaled score based on the adaptive trials led to 44% reduction in error variance for forward memory span and 20% reduction for reverse memory span. The average of these (32%) is similar to but (insignificantly) less than the 42% reduction in error variance that can be predicted based on adding the five adaptive trials.

Conclusions: Replacing live-voice production of digits by a clinician with recorded, computer-controlled production has not affected the difficulty of the test. Adding five additional trials around the sequence length that a test participant can just remember has produced a decrease in measurement error. In addition, the availability of separate scaled scores for the ascending and adaptive phases enables the reliability of the combined score to be checked, for both forward and reverse measurements. The combination of standardized delivery, increased accuracy, internal reliability check, and fast automated scoring makes the test highly suitable for clinical use.

Purpose: There is limited research on the writing of young Spanish-English bilinguals and their writing in both languages. In the current study, we addressed whether written syntax features differed by language (English and Spanish) and varied as a function of grade level, English learner status, and instructional program (dual or English immersion). We also examined whether Spanish and English syntax features were related cross-linguistically and related to writing quality within languages and whether these relations to writing quality were moderated by grade level, English learner status, and instructional program.

Method: We examined written syntax features of Spanish and English essays by simultaneous and emergent bilinguals in Grades 1, 2, and 3 in either Spanish-English dual immersion or English immersion instruction in the United States (N = 278). Essays were scored for quality and evaluated for mean length of T-units, number of verbs, number of noun agreement words, and number of subject agreement words accurately conjugated.

Results: Written syntax features significantly differed by language and varied as a function of grade level, English learner status, and instructional program. Grades 2 and 3 wrote longer utterances, more verbs, and greater noun agreement accuracy than Grade 1. Syntax features were related to writing quality within languages, but Spanish relations were weaker for English learners than non-English learners and for dual immersion students than English immersion students.

Conclusion: Our findings suggest written syntax features may be useful for evaluation of English-Spanish simultaneous and emergent bilinguals' writing.

Purpose: Early detection of language delays is essential, as language is key for academic outcomes, well-being, and societal participation. Previous studies have focused on undetected delays in young children. Much less is known about referrals at older ages. In this study, we aimed to (a) establish how many children are referred at toddler age (2-3 years) and how many at lower elementary (4-7 years), upper elementary (8-12 years), and high school (13-16 years) age; (b) evaluate characteristics of the referred children and adolescents across age groups; and (c) assess whether the ensuing classification (no language disorder [LD], developmental LD, LD + additional problems) differed across age groups.

Method: We used the 2010-2014 database of the Dutch federation of speech and hearing centers, containing 18,894 cases with target ages. We established the number of referrals in each age group (Q1) and assessed the composition of the age groups in terms of speech, language, behavioral, and cognitive outcomes (Q2), as well as in terms of classification (Q3). To answer Q2 and Q3, we conducted chi-squared analyses with the toddler group as reference group.

Results: Late-identified LDs exist: There were new referrals in all age groups. Compared to older age groups, the toddler group contained fewer girls and multilingual children. The toddler group also contained fewer children without an LD and more children with LD + additional problems.

Conclusions: Reassuringly, children with multiple language problems are referred earliest. However, late-identified LDs exist, even at high school age. Girls and multilingual children tend to be missed at younger ages. More work on awareness and identification of language delays is needed, requiring awareness, knowledge, and tools for educational professionals.

Purpose: The Arabic verb system features a nonlinear root and pattern derivational morphology. Previous studies suggest that young Arabic and Hebrew speakers' early verb use is based on semantic complexity rather than derivational morphological structure. The present study examines the role of morphological and semantic complexity in the emergence of the verb derivational morphology in Arabic speaking children with developmental language disorder (DLD) compared to children with typical language development (TLD).

Method: Natural language data were collected from native Arabic-speaking children (40 with DLD; aged 4-6 years and 133 with TLD aged 2;6-6;0 [years;months]) using picture-based elicitation tasks, and verbs were coded morphologically for derivational features and for features of semantic complexity.

Results: The results showed that children with DLD demonstrated a more limited production of verb patterns, both in types and in tokens, than age-matched children with TLD. Also, children with DLD age 5;0-6;0 were similar in types and tokens of verb patterns to younger children with TLD at the age of 3;6-4 years. Moreover, while children with TLD at the age of 2;6-3 years used a smaller number of verb patterns than older 4;0-5;0 aged children with DLD, the two groups were not different in verb semantics. Finally, the morphological and semantic diversity demonstrated by the children with DLD was similar to the morphological and semantic diversity shown by children with TLD.

Conclusion: Our findings support the conclusion that children with DLD and with TLD acquire the derivational verb system in the same pathway and the quantitative lexical differences between the two groups support a delay rather than a deviation from the typical developmental trajectory.

Purpose: Collaboration in the field of speech-language pathology occurs across a variety of digital devices and can entail the usage of multiple software tools, systems, file formats, and even programming languages. Unfortunately, gaps between the laboratory, clinic, and classroom can emerge in part because of siloing of data and workflows, as well as the digital divide between users. The purpose of this tutorial is to present the Collaboverse, a web-based collaborative system that unifies these domains, and describe the application of this tool to common tasks in speech-language pathology. In addition, we demonstrate its utility in machine learning (ML) applications.

Method: This tutorial outlines key concepts in the digital divide, data management, distributed computing, and ML. It introduces the Collaboverse workspace for researchers, clinicians, and educators in speech-language pathology who wish to improve their collaborative network and leverage advanced computation abilities. It also details an ML approach to prosodic analysis.

Conclusions: The Collaboverse shows promise in narrowing the digital divide and is capable of generating clinically relevant data, specifically in the area of prosody, whose computational complexity has limited widespread analysis in research and clinic alike. In addition, it includes an augmentative and alternative communication app allowing visual, nontextual communication.

Purpose: Amyotrophic lateral sclerosis (ALS) is a progressive, ultimately fatal disease causing progressive muscular weakness. Most people living with ALS (plwALS) experience dysarthria, eventually becoming unable to communicate using natural speech. Many wish to use speech for as long as possible. Personalized automated speech recognition (ASR) model technology, such as Google's Project Relate, is argued to better recognize speech with dysarthria, supporting maintenance of understanding through real-time captioning. The objectives of this study are how plwALS and communication partners use Relate in everyday conversation over a period of up to 12 months and how it may change with any decline in speech over time.

Method: This study videoed interactions between three plwALS and communication partners. We assessed ASR caption accuracy and how well they preserved meaning. Conversation analysis was used to identify participants' own organizational practices in the accomplishment of interaction. Thematic analysis was used to understand better the participants' experiences of using ASR captions.

Results: All plwALS reported lower-than-expected ASR accuracy when used in conversation and felt ASR captioning was only useful in certain contexts. All participants liked the concept of live captioning and were hopeful that future improvements to ASR accuracy may support their communication in everyday life.

Conclusions: Training is needed on best practices for customization and practical use of ASR technology and for the limitations of ASR in conversational settings. Support is needed for those less confident with technology and to reduce misplaced allocation of ownership of captioning errors, risking negative effects on psychological well-being.
