Structural Development of Speech Networks in Young Children at Risk for Speech Disorder.

Characterizing the structural development of the neural speech network in early childhood is important for understanding speech acquisition. To investigate speech in the developing brain, 94 children aged 4-7-years-old at risk for early speech disorder were scanned using diffusion weighted imaging (DWI) magnetic resonance imaging (MRI). Additionally, each child completed the Syllable Repetition Task (SRT), a validated measure of phoneme articulation. The DWI data were modeled using multi-compartment restriction spectrum imaging (RSI) to measure restricted and hindered diffusion properties in both grey and white matter. Consequently, we analyzed the diffusion data using both whole brain analysis, and automated fiber quantification (AFQ) analysis to establish tract profiles for each of six fiber pathways thought to be important for supporting speech development. In the whole brain analysis, we found that SRT performance was associated with restricted diffusion in bilateral inferior frontal gyrus ( pars opercularis ), right pre-supplementary/ supplementary motor area (pre-SMA/SMA), and bilateral cerebellar grey matter ( p < .005). Age moderated these associations in left pars opercularis and frontal aslant tract (FAT). However, in both cases only the cerebellar findings survived a cluster correction. We also found associations between SRT performance and restricted diffusion in cortical association fiber pathways, especially left FAT, and in the cerebellar peduncles. Analyses using automatic fiber quantification (AFQ) highlighted differences in high and low performing children along specific tract profiles, most notably in left but not right FAT. These findings suggest that individual differences in speech performance are reflected in structural gray and white matter differences as measured by restricted and hindered diffusion metrics, and offer important insights into developing brain networks supporting speech in very young children.

Exploring Maternal and Infant Health App Development and Effectiveness Research: Scoping Review.

BACKGROUND: Globally, high rates of maternal and infant mortality call for interventions during the perinatal period to engage pregnant people as well as their loved ones in care. Mobile health technologies have become ubiquitous in our lives and in health care settings. However, there is a need to further explore their safety and effectiveness to support and improve health outcomes locally and globally. OBJECTIVE: The aim of this study was to review and synthesize published literature that described the development process or effectiveness evaluations of maternal and infant apps. METHODS: We applied a methodological framework for scoping reviews as well as the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines; in addition, the systematic review platform Covidence (Veritas Health Innovation Ltd) was used to facilitate the review of included studies. Search terms were developed collaboratively, and health sciences-associated databases were searched for studies conducted between January 1, 2000, and February 4, 2022. We excluded studies about apps that only gathered or tracked data or targeted care providers. RESULTS: A total of 1027 articles were included for title and abstract screening, of which 87 (8.47%) were chosen for full-text screening. Of these 87 articles, 74 (85%) were excluded with reasons, and 19 (22%) were included. Four articles were added at data extraction from hand searching and 2 others were excluded. Thus, we reviewed and synthesized data from 11 unique studies reported in 21 articles published between 2017 and 2021. The included studies represented 8 different countries. Most of the apps (8/11, 73%) were in English, although apps were also developed in Arabic, Bahasa Indonesia, and Nepali. The articles reviewed revealed the early stage of development of the field of maternal and infant health apps, with modest evidence of app use and achievement of study outcomes. Only 1 (9%) of the 11 apps was endorsed by an independent health care provider society. App development and evaluation processes emerged, and specific app features were identified as vital for well-functioning apps. End-user engagement occurred in some, but not all, parts of app research and development. CONCLUSIONS: Apps to improve maternal and infant health are being developed and launched in enormous numbers, with many of them not developed with mothers' needs in mind. There are concerns about privacy, safety, and the standardization of current apps as well as a need for professional or institution-specific guidelines or best practices. Despite challenges inherent in currently available apps and their design processes, maternal and infant app technology holds promise for achieving health equity goals and improving maternal and child health outcomes. Finally, we propose recommendations for advancing the knowledge base for maternal and infant apps.

Speech-language pathologists' perceptions of childhood bilingualism.

The value of learning multiple languages has increased in the past 20 years. Despite this, some professionals continue to provide misinformation about bilingualism to many families around the United States, resulting in recommendations of implementing a monolingual approach for children. This study investigated the perceptions held by speech-language pathologists (SLPs) regarding childhood bilingualism. A total of 320 SLPs completed a survey stating their perceptions on childhood bilingualism for typically developing children and children with disabilities. Based on the number of responses, 292 participants were analysed quantitatively utilising a binary logistic regression to identify whether SLPs thought childhood bilingualism was advantageous or neutral, while incorporating the predictors of bilingual status and bilingualism education received. Additionally, a qualitative content analysis was conducted on 173 participants' responses to an open-ended question about their perceptions on childhood bilingualism. Results revealed that SLPs' bilingual status did not predict the probability of an advantageous perception for typically developing children, but it did for children with disabilities; however, SLPs who had received bilingualism education had a higher probability of having advantageous perceptions in both populations. Qualitative results revealed the use of appraisals related to multiple themes. This study served to understand the thoughts of SLPs in relation to the education they are providing to parents and the services they are providing to different populations - whether it be typically developing children or children with disabilities. There are implications for bilingual and cultural-linguistic education to be implemented across graduate programmes to ensure that optimal services are provided to the diverse groups in our case loads.

Pediatric language assessments via telehealth: A systematic review.

INTRODUCTION: Assessment is crucial in the identification of children with potential delays/disorders and allows speech-language pathologists the opportunity to provide early intervention when indicated. For this reason, inaccessibility to formal assessments can be detrimental to the development and progression of overall communication skills for children with language disorders. The COVID-19 pandemic highlighted the need for increased telehealth services and how the provision of these remote services offers a much-needed alternative to face-to-face services for both clinicians and families. METHOD: A systematic procedure involving online literature searches in four electronic databases was employed to identify studies for inclusion in this review. Inclusion criteria were as follows: (1) preschool or elementary pediatric participants, and (2) involve the delivery of language-based assessments via telehealth. Additionally, the search was limited to studies written in English, dated 2010 and newer, and published in peer-reviewed journals. RESULTS: The results of the systematic review showed there was no significant difference between standard scores and behavioral ratings for both face-to-face and telehealth assessments. The studies reviewed determined that telehealth delivery was feasible and presented adequate reliability with high levels of agreement between assessment scores obtained via telehealth and face-to-face. CONCLUSION: Current research suggests that there is no significant difference between remote and face-to-face assessment administration. Additional research is needed to examine the feasibility and reliability of conducting language-based assessments via telehealth in bilingual children, children younger than four years of age, and in different environments, such as schools or clinics.

Considerations for Addressing the Needs of Culturally and Linguistically Diverse Speech-Language Pathology Praxis Test Takers.

PURPOSE: The primary purpose of this article is to explore the speech-language pathology (SLP) Praxis test, a barrier to culturally and linguistically diverse (CLD) individuals entering the profession, by investigating first-time pass rates and mean scores by test taker race/ethnicity. Other potential barriers to licensure and certification, as well as solutions for mitigating these barriers, will also be addressed. METHOD: SLP Praxis test data from two windows of time, 2008-2011 and 2014-2020, were compared for the following: (a) proportions of test taker race/ethnicity relative to U.S. demographic estimates of racial/ethnic group proportions overall, (b) proportions of racial/ethnic groups, and (c) trends in test-taker mean scores by race/ethnicity. First-attempt pass rates by racial/ethnic groups were also calculated for the 2014-2020 testing window. RESULTS: The percentage of some CLD SLP Praxis test-taker groups increased since the 2008-2011 testing window but is still not representative of U.S. racial/ethnic demographics. The first-attempt pass rates and overall mean scores of CLD test-taker groups remained substantially lower than White non-Hispanic/Latinx test takers. CONCLUSIONS: Despite the encouraging trends in SLP Praxis test-taker racial/ethnic diversity, disparities persist between the racial/ethnic makeup of SLP Praxis test takers and the demographic makeup of the United States. Consequently, these disparities have implications for the continued lack of cultural representativeness seen in our workforce.
