Purpose: This study examined the speech acoustic characteristics of Jamaican Creole (JC) and English in bilingual preschoolers and adults using acoustic duration measures. The aims were to determine if, for JC and English, (a) child and adult acoustic duration characteristics differ, (b) differences occur in preschoolers' duration patterns based on the language spoken, and (c) relationships exist between the preschoolers' personal contextual factors (i.e., age, sex, and percentage of language [%language] exposure and use) and acoustic duration. Method: Data for this cross-sectional study were collected in Kingston, Jamaica, and New York City, New York, United States, during 2013-2019. Participants included typically developing simultaneous bilingual preschoolers (n = 120, ages 3;4-5;11 [years;months]) and adults (n = 15, ages 19;0-54;4) from the same linguistic community. Audio recordings of single-word productions of JC and English were collected through elicited picture-based tasks and used for acoustic analysis. Durational features (voice onset time [VOT], vowel duration, whole-word duration, and the proportion of vowel to whole-word duration) were measured using Praat, a speech analysis software program. Results: JC-English-speaking children demonstrated developing speech motor control through differences in durational patterns compared with adults, including VOT for voiced plosives. Children's VOT, vowel duration, and whole-word duration were produced similarly across JC and English. The contextual factor %language use was predictive of vowel and whole-word duration in English. Conclusions: The findings from this study contribute to a foundation of understanding typical bilingual speech characteristics and motor development as well as schema in JC-English speakers. In particular, minimal acoustic duration differences were observed across the post-Creole continuum, a feature that may be attributed to the JC-English bilingual environment.

The Focus on the Outcomes of Communication Under Six (FOCUS) is one of a few validated outcome measures related to children's communicative participation. Additional validation of the FOCUS measure could address the paucity of validated outcomes-based measures available for assessing preschool-age children, particularly for those who are multilingual. The data collected for this study, with a representative sample of Jamaican Creole-English speaking children, extend the applicability of the FOCUS to a broader range of preschoolers and expand psychometric evidence for the FOCUS to a multilingual and understudied context.

Purpose: The aim of this study was to characterize speech acoustics in bilingual preschoolers who speak Jamaican Creole (JC) and English. We compared a standard approach with a culturally responsive approach for characterizing speech sound productions. Preschoolers' speech productions were compared to adult models from the same linguistic community as a means for providing confirmatory evidence of typical speech patterns specific to JC-English speakers. Method: Two protocols were applied to the data collected using the Diagnostic Evaluation of Articulation and Phonology (DEAP) Articulation subtest: (a) the standardized DEAP protocol and (b) a culturally and linguistically adapted protocol reflective of the Jamaican post-Creole (English to Creole) continuum. The protocols were used to analyze responses from JC-English-speaking preschoolers (n = 119) and adults (n = 15). Responses were analyzed using acoustic (voice onset time, whole-word duration, and vowel duration) and perceptual (percentage of consonant correct-revised and response frequencies) measures. Results: The culturally responsive protocol captured variation in the frequency and acoustic differences produced in the post-Creole continuum, with higher amounts of "other" responses compared to "standard" target responses for both children and adults. Adults' whole-word durations were shorter and showed more consistent prevoicing during initial plosives compared to the children. Conclusions: Applying culturally responsive methods, including knowledge of the variation produced in the post-Creole continuum and with adult models from the same linguistic community, improved the ecological validity of speech characterizations for JC-English preschoolers. Acoustic properties of speech should be investigated further as a means of describing bilingual development and distinguishing between difference and disorder.

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.

Purpose: The aim of this study was to investigate the appropriateness of standardized assessments of expressive grammar and vocabulary in a sample of preschool-age dual language learners (DLLs) who use Jamaican Creole (JC) and English. Adult models from the same linguistic community as these children were used to inform culturally and linguistically appropriate interpretation of children's responses to a standardized assessment. Method: JC-English-speaking preschoolers (n = 176) and adults (n = 33) completed the Word Structure and Expressive Vocabulary subtests of the Clinical Evaluation of Language Fundamentals Preschool--Second Edition. Adults' responses were used to develop an adapted scoring procedure that considered the influence of JC linguistic features on responses. DLLs' responses scored using the standard English and adapted JC procedures were compared. Results: JC-English DLLs and adults used similar linguistic structures in response to subtest questions. DLLs' scores differed significantly from the standardized sample on both subtests. Preschoolers received higher raw and corresponding standard scores with adapted scoring compared to standard scoring. Adapted scoring that made use of adult models yielded high classification accuracy at a rate of 93.8% for Word Structure and 92.1% for Expressive Vocabulary. Conclusions: Adapting standardized assessment scoring procedures using adult models may offer an ecologically valid approach to working with DLL preschoolers that can support a more accurate assessment of language functioning. These findings suggest that the use of standardized assessments for bilingual JC-English speakers requires a culturally responsive approach.

Predictors of expressive grammar were compared in formal and naturalistic assessment tasks for children with typically developing (TD) language and with Developmental Langauge Disorder (DLD). Standardized expressive language assessments were administered to 110 preschoolers. The parents of these children reported whether or not they were concerned about their child's speech and language development. Stepwise regression analyses revealed receptive language as the only significant predictor of expressive grammar across assessment tasks. For TD preschoolers, receptive vocabulary and grammar accounted for expressive grammar performance in the formal task; however, only receptive grammar accounted for performance in the naturalistic task. For DLD preschoolers, only receptive vocabulary accounted for expressive grammar performance across both tasks. Nonverbal IQ and parent concern did not predict expressive grammar performance in either task. Implications for treatment of preschool DLD using relative strengths in vocabulary are discussed.

Purpose: The purpose of this study is to characterize narrative competence of typically developing bilingual children using Jamaican Creole (JC) and English. Method: Story comprehension and fictional storytelling tasks in JC and English were completed by 104 bilingual preschoolers aged 4-6 years. Story comprehension was analyzed using inferential story comprehension questions representing Blank's Question Hierarchy. Fictional storytelling was analyzed using the Monitoring Indicators of Scholarly Language framework for narrative macrostructure and microstructure. Results: Story comprehension was significantly correlated within each language, but only questions from Level 4 of Blank's Question Hierarchy showed significant correlations between languages. Fictional storytelling was significantly better in English than in JC for macrostructure (total score, internal response, plan, consequence) and microstructure (total score, adverbs, elaborated noun phrases). Story complexity in JC and English was significantly correlated. In terms of developmental effects, children's macrostructure and story complexity appear to be better at 4 years than 5 years, with English outperforming JC. Furthermore, age correlated with story comprehension in JC. Conclusion: Comparison of narrative competence in bilingual children provides much needed insights into language development, with examination of JC and English bilinguals representing an understudied bilingual context.

Most research related to communication skills in children with autism spectrum disorder (ASD) has been obtained from monolingual English-speaking children from high-income countries. Based on questionnaires completed by parents, this pilot study aimed to describe the communication characteristics of six children with ASD living in Jamaica. Parents had concerns about their child's speech intelligibility, expressive language, and social communication. All children were reported to speak using Standard Jamaican English (SJE). Exposure to SJE and Jamaican Creole (JC) was reported by half of the parents. Emergent literacy was considered a relative strength. All parents reported that their child could recite the alphabet and identify some letters and that family members also helped their child print and read letters or words. Other aspects of the home literacy environment and early literacy skills were varied. Information from this group provides some insights into communication skills in children with ASD from Caribbean backgrounds.

Purpose: The purpose of this scoping review was to identify current measures used to evaluate the language abilities of multilingual preschoolers within the framework of the International Classification of Functioning, Disability and Health--Children and Youth Version (ICF-CY; World Health Organization, 2007). Method: This review adhered to established models for conducting a comprehensive, iterative scoping review outlined by Arksey and O'Malley (2005) and Levac, Colquhoun, and O'Brien (2010) and included the following phases: (a) articulating the research question; (b) identifying relevant studies; (c) selecting studies; (d) charting the data; and (e) collating, summarizing, and reporting the results. The ICF-CY was used to frame the identified measures (World Health Organization, 2007). Results: Three hundred twenty-five peer-reviewed publications were identified and included in this review. The majority of publications used measures that evaluated the activity component of multilingual preschoolers' language (70%), with few evaluating participation (9%). Most identified measures (73%) assessed children's semantic language skills. We also observed that 88% of studies explicitly measured children's language input to interpret assessment results. Conclusions: A variety of measures are currently used that address the activity component of the ICF-CY with a particular emphasis on semantics. There is, however, a dearth of measures examining language abilities for participation. The authors strongly recommend an increased focus on the development, use, and evaluation of measures that explicitly assess multilingual preschoolers' language participation, particularly in school-based settings.

Purpose: The purpose of this study was to characterize grammatical production in Jamaican Creole (JC) and English using the Index of Productive Syntax (IPSyn; Scarborough, 1990) in a sample of typically developing bilingual Jamaicans. Method: Spontaneous language samples were collected in JC and English from 62 preschoolers aged 4-6 years. Language samples were analyzed for IPSyn subdomains (Total Score, Noun Phrases, Verb Phrases, Questions/Negations, Sentence Structures), mean length of utterance in morphemes, and number of different words. Child and family demographic information were also collected along with nonverbal IQ performance. Results: IPSyn Total Score in JC and English were significantly correlated, and significant correlations were found between IPSyn subdomains in each language for Noun Phrases, Verb Phrases, and Sentence Structures, but not Questions/Negations. Item analysis for the IPSyn items showed that only 7 of the 56 items did not perform similarly in both languages, with performance on only 2 of these being significantly different. IPSyn scores in both languages were correlated with mean length of utterance in morphemes and number of different words, but only IPSyn JC was correlated with nonverbal IQ and age. Conclusion: The IPSyn shows promise as a mainstream tool useful in characterizing grammatical productions across languages in typically developing bilingual Jamaican preschoolers.

This study compared language samples from typically developing 4-year-olds who spoke African American English (AAE), Jamaican English (JE), or Mainstream American English (MAE) to assess the value of using language sample analysis (LSA) measures for characterising language use across dialects of English. Specific LSA metrics included mean length of utterance (MLU) in morphemes and in words, the Index of Productive Syntax (IPSyn), Developmental Sentence Scoring (DSS) and measures of lexical diversity. Children demonstrated diverse linguistic patterns across dialects, but a Kruskal–Wallis H test did not reveal significant differences in scores obtained through LSA measures. Notably, the IPSyn captured morphosyntactic structures in each category across dialects where prior research has highlighted limitations. This preliminary study uses a case-based approach to illustrate the applicability of LSAs in describing linguistic variations across children who speak different dialects of English. Moreover, the findings from this study underscore the potential use of LSAs in describing linguistic patterns to support the characterisation of communication profiles for culturally and linguistically diverse children.

Purpose: The purpose of this study was to characterize the communicative participation and functional speech intelligibility (i.e., how children use communication and how well they are understood across everyday life) of typically developing (TD) bilingual Jamaican preschoolers and those with functionally defined speech sound disorders (fSSDs) in the COVID-19 milieu. Findings were also compared to an existing corpus of baseline data to document and explore differences in children's speech-language outcomes secondary to pandemic-related social restrictions. Method: Thirty bilingual Jamaican preschoolers, 21 TD and nine with fSSDs, were assessed during the pandemic via telepractice. Association and univariate mean testing were completed to characterize children's communicative participation and functional speech intelligibility. Data were then compared to an existing corpus of baseline data (collected in person between 2013 and 2019), which included direct child assessment and parent reports and consisted of TD (n = 226) Jamaican Creole-English--speaking preschoolers and those with fSSDs (n = 39) to compare performance profiles across data sets. All participants attended schools in Kingston, Jamaica. Results: Measures of communicative participation remained stable in the context of the COVID-19 milieu for children in the TD and fSSD groups, but functional speech intelligibility outcomes for children with fSSDs deviated between in-person findings collected from children pre-pandemic. Between-groups differences were also found on measures of speech production accuracy but were no longer significant when considering telepractice as a covariate. Conclusions: Findings from this investigation serve to characterize the communicative participation and functional speech intelligibility of TD bilingual Jamaican preschoolers and those with fSSDs in the COVID-19 milieu. By extension, the results comparing data from preschoolers collected during the pandemic to an existing corpus of baseline data from a different group of preschoolers provide critical insights about multilingual children's speech-language outcomes in the context of acutely changing environmental circumstances.

Purpose: The aim of this tutorial is to support speech-language pathologists' (SLPs') application of the International Classification of Functioning, Disability and Health (ICF) in assessment and treatment practices with children with language impairment. Method: This tutorial reviews the framework of the ICF, describes the implications of the ICF for SLPs, distinguishes between students' capacity to perform a skill in a structured context and the actual performance of that skill in naturalistic contexts, and provides a case study of an elementary school child to demonstrate how the principles of the ICF can guide assessment and intervention. Implications: The Scope of Practice and Preferred Practice documents for the American Speech-Language-Hearing Association identify the ICF as the framework for practice in speech-language pathology. This tutorial will facilitate clinicians' ability to identify personal and environmental factors that influence students' skill capacity and skill performance, assess students' capacity and performance, and develop impairment-based and socially based language goals linked to Common Core State Standards that build students' language capacity and their communicative performance in naturalistic contexts.

Purpose: The purpose of this scoping review was to identify current measures used to evaluate speech-language outcomes for preschoolers with communication disorders within the framework of the International Classification of Functioning, Disability and Health-Children and Youth Version (ICF-CY; World Health Organization, 2007). Method: The review involved 5 phases outlined by Arksey and O'Malley (2005) and further developed by Levac, Colquhoun, and O'Brien (2010): (a) articulating the research question; (b) identifying relevant studies; (c) selecting studies; (d) charting the data; and (e) collating, summarizing, and reporting the results. The ICF-CY was used to frame the measures included. Results: A total of 214 relevant peer-reviewed publications were included in the review. Most publications used measures to evaluate changes in outcomes for Activities (65%), followed by measures evaluating changes in Body Functions (20%), and finally measures evaluating changes at the level of Participation (15%). There has been a slight increase in the evaluation of Participation-based outcomes in the past 4 years (2012-2015). Conclusion: The review revealed a dearth of measures in the pediatric speech-language literature that address Participation-based outcomes. The authors strongly advocate for the use of Participation-based outcome measures to detect meaningful change in the lives of children and families.

The purpose of this article is to describe communicative-participation outcomes measured by the Focus on the Outcomes of Communication Under Six (FOCUS©; Thomas-Stonell et al., 2013) for interventions provided by speech-language pathologists (SLPs) in different community settings for preschoolers with speech-language impairments (Sp/LI) with and without developmental mobility impairments (MI). The predictive relationships between communicative-participation and (1) functioning-and-disability, and (2) contextual factors, was also investigated. Sixty-one preschoolers with Sp/LI and their parents participated. Twenty-six preschoolers were identified with Sp/LI and received speech-language interventions (Group 1), 20 preschoolers were identified with Sp/LI and MI and received speech-language interventions (Group 2), and 15 preschoolers with Sp/LI awaiting intervention served as waitlist controls (Group 3). Parents completed structured interviews about children's communicative-participation outcomes using the FOCUS© at three time points (pre-intervention, post-intervention, and 3-months post-intervention) with an SLP. Only Groups 1 and 2 experienced statistically and clinically meaningful communicative-participation outcomes over time as measured by the FOCUS©. Pre- to post-intervention communicative-participation was predicted by functioning-and-disability and contextual factors, initial social skills and intervention status, respectively. Post-intervention to 3-month post-intervention scores were also predicted by functioning-and-disability and contextual factors, risk status (Sp/LI only, Sp/LI+developmental MI) and intervention status, respectively. Significant and clinically meaningful changes in communicative-participation over time are associated with speech-language interventions for preschoolers with Sp/LI.

Purpose: To determine whether (a) expressive grammar intervention facilitated social and emergent literacy outcomes better than no intervention and (b) expressive grammar gains and/or initial expressive grammar level predicted social and emergent literacy outcomes. Method: This investigation was a follow-up to a recently published study exploring the impact of grammatical language intervention on expressive grammar outcomes for preschoolers with specific language impairment (SLI). Twenty-two 3- to 5-year-old preschoolers received ten 20-minute intervention sessions addressing primary deficits in grammatical morphology. Participants' social and emergent literacy skills were not targeted. Twelve children awaiting intervention, chosen from the same selection pool as intervention participants, served as controls. Blind assessments of social and emergent literacy outcomes were completed at preintervention, immediately postintervention, and 3 months postintervention. Results: Only intervention participants experienced significant gains in social and emergent literacy outcomes and maintained these gains for 3 months postintervention. Expressive grammar gains was the only single significant predictor of these outcomes. Conclusions: Expressive grammar intervention was associated with broad impacts on social and emergent literacy outcomes that were maintained beyond the intervention period. Gains in expressive grammar predicted these outcomes. Social and emergent literacy skills were positively affected for preschoolers with SLI during a grammatical language intervention program.

This study was conducted as a follow-up analysis to two prior studies using existing data gathered in those original studies. In the current study, we focus on those preschoolers who received one of two interventions that varied in terms of the level of visual supports for grammatical elements (n = 22 of the original 34 participants). Utilizing random selection for intervention, our study examined potential session-to-session differences in rate of progress between two interventions. One intervention provided visual support using color-coded screens and syntactic slots for grammatical and semantic sentence elements (Group 1, Computer-Assisted Intervention, n = 11). The other intervention provided visual support through objects in play, books, and picture cards with actions for semantic elements only (Group 2, Table-Top Intervention, n = 11). Both interventions targeted accurate production of a basic simple sentence (i.e., third person singular present progressive sentences). Twenty-two, 3- to 5-year-old preschoolers with specific language impairment (SLI) participated in 20-minute once weekly sessions. Both interventions included sentence breakdown (i.e., breaking sentences into subject, verb, object components that are trained to an 80% criterion) and build-up (i.e., putting the entire sentence together). Rate of progress in intervention was monitored for (a) efficiency (first session that the 80% criterion was achieved) and (b) syntactic growth (movement beyond the basic simple sentence level). Blinded assessors scored session-to-session data to establish potential differences in rate of progress between groups. The results showed that Group 1 outperformed Group 2 for efficiency and syntactic growth. This study demonstrated that use of multiple visual supports in expressive grammar training facilitated a therapeutic advantage in session-to session grammatical learning for preschoolers with SLI.

Due to the lack of normative data about bilingual speech development and limited availability of diagnostic tools optimised for this population, bilingual children under consideration for speech-language services are at an elevated risk of misdiagnosis. In the absence of validated assessment tools, speech-language pathologists may use measures of accuracy and variability of speech production to diagnose suspected speech sound disorders in bilingual children. Research in general motor development suggests that variability and accuracy may trade off in the course of maturation, whereby movement variability spikes before the transition to a more mature stage of motor control. Such variability-accuracy tradeoffs have been described in monolingual speech development but are understudied in bilingual populations, where cross-linguistic transfer occurs. This study aimed to examine variability, accuracy, and cross-linguistic transfer in the speech of 20 bilingual children speaking Jamaican Creole and English. We hypothesised that children who showed higher accuracy in their productions would also exhibit more variable speech, indicating a variability-accuracy tradeoff. The Word Inconsistency Assessment from the Diagnostic Evaluation of Articulation and Phonology was administered to measure accuracy and variability in the English context, where misdiagnosis is likely to occur. Contrary to our hypothesis, we observed that individuals with higher accuracy tended to be less variable in their productions. Future research should examine longitudinal trajectories of accuracy and variability and consider a more culturally-appropriate definition of 'accuracy' in documenting bilingual speech sound development.

Purpose: The impact of a newly designed computer-assisted treatment ("C-AT") program, "My Sentence Builder", for the remediation of expressive-grammar deficits in children with specific language impairment (SLI) was explored. This program was specifically designed with features to directly address expressive-grammar difficulties, thought to be associated with hypothesized deficits in verbal working memory (VWM). Method: Thirty-four preschoolers with deficits in expressive-grammar morphology participated. Using the randomization procedure of consecutive sampling, participants were recruited. Twenty-two participants were consecutively assigned to one of two treatment groups, "C-AT" or non "C-AT" ("nC-AT"). The "nC-AT" utilized conventional language stimulation procedures containing features which have been traditionally used to address expressive-grammar deficits. A group of equivalent children awaiting treatment and chosen from the same sample of children as the treatment participants served as a control group. Blind assessments of outcomes were completed pre-, post-, and 3-months post-treatment in a formal and informal context. Results: "C-AT" and "nC-AT" participants significantly outperformed controls pre-to-post to 3-months post-treatment in both assessment contexts. No significant differences in treatment gains were found between "C-AT" and "nC-AT." Conclusion: Results suggested that treatments designed to directly address expressive-grammar deficits were better than no treatment for preschool SLI. Further, use of a "C-AT" program may be another feasible treatment method for this disorder population. Learning outcomes: As a result of this activity, the reader will recognize that: (1) expressive-grammar treatment is better than no treatment for immediate and continued language growth, (2) use of a "C-AT" program containing specific features designed to directly address expressive-grammar deficits is another viable, but not necessarily a better treatment option for the remediation of expressive-grammar deficits in preschool children with SLI, and (3) different outcome contexts yield distinct yet equally important findings about growth in children's expressive-grammar skills with treatment.

To conduct an exploratory study to establish construct validity of the Focus on the Outcomes of Communication Under Six (FOCUS) in the Jamaican context for FOCUS Total and Profile scores. Parents of a representative sample of 3-to-6-year-old Jamaican Creole (JC)-English-speaking simultaneous bilingual children completed the FOCUS in English, and the Intelligibility in Context Scale (ICS) in JC and in English. Children completed the Diagnostic Evaluation of Articulation and Phonology (DEAP) in both languages. Percent phonemes, consonants, and vowels correct were calculated using single word responses to DEAP items. Pearson correlations were completed to describe relationships between measurement scores. Convergent validity was found for FOCUS Total and ICS/JC scores. Convergent and divergent validity were found for specific FOCUS Profile scores and ICS/JC scores. Minimal evidence of convergent validity was found with FOCUS Total scores and transcription-based measures of speech production in JC and in English. Convergent and divergent validity were found between specific FOCUS Profile scores and some transcription-based measures of speech production in JC and in English. This study provides evidence of construct validity for FOCUS Total and Profile scores. It also provides validity evidence for FOCUS scores in a multilingual context using a representative sample of children that serves to broaden the range of applicability of the FOCUS.

Purpose: The purpose of this study was to investigate the clinical application of the Intelligibility in Context Scale (ICS) instrument in children with velopharyngeal insufficiency (VPI). This study investigated the relationship between clinical speech outcomes and parental reports of speech intelligibility across various communicative partners. Methods: The ICS was completed by the parents of 20 English-speaking children aged 4–12 years diagnosed with VPI. The parents were asked to rate their children's speech intelligibility across communication partners using a 5-point scale. Clinical metrics obtained using standard clinical transcription on the Picture-Cued SNAP-R Test were: (1) percentage of consonants correct (PCC), (2) percentage of vowels correct (PVC), and (3) percentage of phonemes correct (PPC). Nasalance from nasometer data was included as an indirect measure of nasality. Intelligibility scores obtained from naive listener's transcriptions and speech-language pathologists' (SLP) ratings were compared with the ICS results. Result: Greater PCC, PPC, PVC, and transcription-based intelligibility values were significantly associated with higher ICS values, respectively (r[20] = 0.84, 0.82, 0.51, and 0.70, respectively; p < 0.05 in all cases). There was a negative and significant correlation between ICS mean scores and SLP ratings of intelligibility (r = –0.74; p < 0.001). There was no significant correlation between ICS values and nasalance scores (r[20] = –0.28; p = 0.22). Conclusion: The high correlations obtained between the ICS with PCC and PPC measures indicate that articulation accuracy has had a great impact on parents' decision-making regarding intelligibility in this population. Significant agreement among ICS scores with naive listener transcriptions and clinical ratings supports use of the ICS in practice. [ABSTRACT FROM AUTHOR]

The present study investigated the sensitivity and specificity of the English Intelligibility in Context Scale (ICS) and the ICS-Jamaican Creole (ICS-JC) translation with bilingual preschool-aged Jamaican children. Participants in this study were 262 English-Jamaican Creole simultaneous bilingual children (aged 3;3 to 6;3, M = 4;11, SD = 7.8). The ICS and ICS-JC were administered to parents in auditory form, rather than written form. Although recent evidence has demonstrated the validity and reliability of the ICS as an assessment tool in various languages, further data are needed to determine diagnostic accuracy of the ICS and ICS-JC in Jamaican children. The sensitivity and specificity of both tools were high in this cohort of children, indicating that in the Jamaican context, these versions of the ICS could be used as screening tools to identify children who require further assessment of speech sound disorders. A cut-off score of 4.12 was used for both tools to achieve high sensitivity (0.84) and specificity (0.70) values for the ICS, as well as high sensitivity (0.84) and specificity (0.71) for the ICS-JC. The results of this study also demonstrate that administration of the auditory ICS is a valid way of collecting parent reports about children's speech intelligibility, which has implications for use of the ICS in languages with no written form or with parents who have a low level of literacy in the languages they use. This investigation is relevant not only to this underserved population but broadens knowledge of research-based tools for working with bilingual children. [ABSTRACT FROM AUTHOR]

This study analysed grammatical development in a sample of 3- to 4-year-olds with specific language impairment (SLI) over time. The authors sought to determine if expressive grammar intervention resulted in accelerated gains in morphosyntax to "within normal limits" performance in expressive grammar for this age group. For this analysis, spontaneous language outcomes following expressive grammar intervention were compared between preschoolers receiving intervention (n = 22) and those not receiving intervention, no intervention waitlist-controls (n = 12). We examined: (a) growth in grammatical complexity and morpheme use, and (b) per cent error rates in three grammatical categories. We found that intervention was more effective than no intervention in facilitating accelerated performance for grammatical complexity, growth in morpheme use, and lower per cent error rates in targeted grammatical categories. This study provides evidence that expressive grammar intervention is associated with accelerated development in grammar skills for preschoolers with SLI. [ABSTRACT FROM AUTHOR]
