Background: Individuals with developmental language disorder or Williams syndrome are reported to use more gestures than individuals with typical development. However, these two groups differ considerably in visuospatial and language skills, two skills that are hypothesized to shape gesture rate. Aims: We first examined whether children with both developmental language disorder and children Williams syndrome do indeed use more gestures. Our second aim was to disentangle the role of vocabulary and visuospatial skills in the use of supplementary gestures (i.e., containing unique information). To account for participant heterogeneity, analyses included both group comparisons and vocabulary and visuospatial skills at an individual level. As a third aim, the role of visuospatial skills was further examined in relation to gestures containing spatial content. Methods & Procedures: In a cross‐sectional group design, three participant groups watched and then retold a cartoon: children with typical development (n = 25), children with developmental language disorder (n = 25) and children/young people with Williams syndrome (n = 14). Their narrations were transcribed and hand gestures were coded based on gesture–speech integration (redundant, adds information to particular lexical items, gives information that is entirely absent from speech) and spatial content. Participants' expressive vocabulary and visuospatial skills were measured. Outcomes & Results: Between‐group comparisons showed that individuals with developmental language disorder or Williams syndrome did indeed use more gestures. Poisson loglinear modelling demonstrated that a relative higher use of supplementary gestures was determined by lower expressive vocabulary skills. Neither the group distinction nor visuospatial skills shaped the supplementary gesture rate nor spatial gesture rate. Conclusions & Implications: Regardless of neurodevelopmental condition or typical development, a higher use of supplementary gestures was influenced by expressive vocabulary skills. Children with lower vocabulary skills spontaneously capitalized on the multimodality of communication to express constituents that were not present in their verbal speech. This finding is a promising starting point for future gesture intervention studies examining whether implicit modelling of gesture use can encourage gestures even more in these children and if this allows them to achieve higher linguistic complexity. On a methodological note, the observed intra‐group skill variability demonstrates that group comparisons need to be complemented with correlational measures accounting for skills at an individual level. What this paper adds: What is already known on the subject: Children with developmental language disorder and children with Williams syndrome are more inclined to use gestures than typically developing children. Research conducted in adults with typical development points towards the role of lexical and visuospatial skills in gesture use, but it is unclear how these skills shape gesture use in children with atypical development. What this paper adds to existing knowledge: This study compares the rate of gestures that convey meaning that is not expressed in speech between the three aforementioned populations. Novel is the inclusion of the group distinction, individual lexical skills, and visuospatial skills in one encompassing statistical model. What are the potential or actual clinical implications of this work?: The inclination to use gestures that replace speech is related to lexical skills. Visuospatial skills do not seem to play a role and should not be considered as a factor when thinking about gesture intervention. Understanding how gestures relate to specific skills is a first step to understanding how gesture interventions can bolster language production. [ABSTRACT FROM AUTHOR]

Background: There is limited evidence concerning the longer term language, literacy and cognitive skills of young adults with developmental language disorder (DLD). Studies that exist suggest continuing difficulties with language and reading, but abilities may change over time. Aims: This study aimed to examine the language, literacy and cognitive skills of young adults with and without DLD. Methods & Procedures: Data were used from the Manchester Language Study data set which was collected from a group of young adults with DLD (recruited originally at 7 years of age from language units—specialist educational resource bases). Participants were assessed on their language, literacy and cognitive functioning when they were aged 24. A comparison group of age‐matched peers (AMPs; also 24 years old) were also assessed. For language and cognition, change in scores between 16 and 24 years was also available for analysis. Finally, self‐rated measures of literacy difficulties were taken at 24 years for functional reading and writing. Outcome & Results: The results indicate that the young people with DLD in this sample continue to perform more poorly as a group on formal oral and written language tests. A small but significant minority of young adults with DLD also report functional reading and writing difficulties compared with AMPs despite reporting reading as often as their peer group. Compared with scores at 16 years of age, this subsample now appears to show slightly less risk of non‐verbal IQ difficulties, showing small but significant 'catch‐up' to AMPs. Conclusions & Implications: These preliminary data suggest that at least some individuals with DLD experience marked linguistic difficulties in adulthood, and that the pathways of language, literacy and cognition are not entirely parallel for this group. Continued support and awareness of challenges for young adults with DLD may be useful. What this paper addsWhat is already known on the subjectIt is known that DLD is long term and persists into adulthood. There has recently been a body of work reporting on the well‐being of this population, as well as their employment, financial status and driving ability. However, there is very little information about language, literacy and cognitive skills beyond school age.What this paper adds to existing knowledgeThis study presents data on language, literacy and cognition from a large cohort of young adults with DLD and their AMPs. In this sample, a large proportion of participants score low on language, with fewer scoring as impaired on literacy and cognition. A significant minority reports difficulties in functional reading. Preliminary analysis appears to suggest that while language development remains depressed, non‐verbal cognitive skills show some catch up over time.What are the potential or actual clinical implications of this work?Increased awareness and continued support for language, literacy and cognition may be useful for young adults with DLD.

Background: Understanding the natural history of developmental speech and language impairments can support the selection of children whose difficulties are persistent rather than transitory. It can also provide information against which the effectiveness of intervention can be evaluated. However, natural history data are difficult to collect ethically. Furthermore, as soon as an impairment is identified, the behaviour of those around changes, thus creating some level of intervention. Longitudinal cohort studies, where intervention is minimal, or the control arm of randomized trials have provided the best evidence. However, occasional opportunities arise where service waiting lists can provide data about the progress of children who have not received intervention. This natural history study arose within an ethnically diverse, community paediatric speech and language therapy service in the UK where levels of social disadvantage are high. Aims: To identify (1) the characteristics of the children who attended initial assessment and were selected for treatment; (2) the differences between children who did and did not attend reassessment; and (3) the factors associated with outcomes. Methods & Procedures: A cohort of 545 children were referred and assessed as in need of therapy. Due to resource constraints, intervention was not available for an average of 12 months. Children were invited to attend for a reassessment of need. Initial and follow‐up assessments were conducted by experienced clinicians using service guidelines and the Therapy Outcomes Measures Impairment Scale (TOM‐I). Descriptive and multivariate regression analyses examined child outcomes for changes in communication impairment, demographic factors and length of wait. Outcomes & Results: At initial assessment, 55% of children presented with severe and profound communication impairments. Children offered appointments at clinics in areas of high social disadvantage were less likely to attend reassessment. By reassessment, 54% of children showed spontaneous improvement (mean TOM‐I rating change = 0.58). However, 83% were still judged to require therapy. Approximately 20% of children changed their diagnostic category. Age and impairment severity at initial assessment were the best predictors of continuing requirement for input. Conclusions & Implications: Although children do make spontaneous progress post‐assessment and without intervention, it is likely that the majority will continue to be assigned case status by a Speech and Language Therapist. However, when evaluating the effectiveness of interventions, clinicians need to factor in the progress that a proportion of the caseload will make spontaneously. Services should be mindful that a lengthy wait may disproportionately impact children who already face health and educational inequalities. What This Paper Adds: What is already known on the subject: Data from longitudinal cohorts (where intervention has been minimal) and the no treatment control arms of randomized controlled trials have provided the best evidence of the natural progression of speech and language impairments in children. These studies provide a varied rate of resolution and progress depending on the case definitions and measurements used. What this study adds to existing knowledge: Uniquely, this study has evaluated the natural history of a large cohort of children who had been waiting for treatment for up to 18 months. Data showed that, over a period of waiting for intervention, the majority of those identified as a case by a Speech and Language Therapist remained a case. Using the TOM, on average children in the cohort made just over half a rating point progress during their waiting period. What are the potential or actual clinical implications of this work?: The maintenance of treatment waiting lists is probably an unhelpful service strategy for two reasons: first, the case status of the majority of the children is unlikely to change whilst they await intervention and thus children and their families are subjected to further limbo waiting time; second, the dropout from the waiting list may disproportionately affect children who are offered appointments in clinics where there are higher levels of social disadvantage, thus exacerbating inequalities in the system. Currently, a suggested reasonable outcome of intervention is a 0.5 rating change in one domain of TOMs. Study findings suggest this is insufficiently stringent for a paediatric community clinic caseload. There is a need to evaluate spontaneous improvement which may occur in other TOM domains (i.e., Activity, Participation and Wellbeing) and to agree an appropriate change metric for a community paediatric caseload.

Background: Despite its importance, in-depth analysis of connected speech is often neglected in the diagnosis of primary progressive aphasia (PPA) - especially for the logopenic variant (lvPPA) for which unreliable differential diagnosis has been documented. Only a few studies have been conducted on this topic in lvPPA. Aims: The aim of this study was to describe and compare lexico-semantic and morphosyntactic features of connected speech in participants with lvPPA, in comparison with healthy controls, using three different elicitation tasks (i.e., picture description, story narration and semi-structured interviews). In addition to a number of discourse features, we were particularly interested in the presence or absence of syntactic deficits in this PPA variant in line with recent findings. Methods & Procedures: A prospective group study was conducted to compare lvPPA participants (n = 13) to age- and education-matched healthy controls (n = 13). For each individual, connected speechwas obtained using three tasks: (1) The Cookie Theft picture description; (2) Cinderella Story; (3) Topic-directed interview. Production on each task was recorded, transcribed and analysed according to the Quantitative Production Analysis (QPA) protocol, a tool developed by Berndt et al. (2000) for the analysis of sentence production in aphasia. Differences between lvPPA and healthy controls and among elicitation tasks were analysed using repeatedmeasuresmultilevelmixed-effects regression, separately for each outcome. Outcomes & Results: Four measures were significantly different between lvPPA participants and healthy controls across all elicitation tasks. Specifically, lvPPA participants produced a reduced proportion of open-class words, a higher proportion of verbs, a higher proportion of pronouns and fewer well-formed sentences. For these measures, the difference between lvPPA and healthy controls was consistent among elicitation tasks, except for the proportion of well-formed sentences, where the difference between the two groupswas significantly greater in the story narration task than in the other tasks. Conclusions & Implications: Across elicitation tasks that used the same analysis protocol (i.e., QPA), a similar pattern of deficits in connected speech emerged in lvPPA patients. Importantly, the findings replicate previous studies, which used different elicitation tasks and analysis protocols. Especially in relation to the documented syntactic deficits, these findings provide implications for differential diagnosis in PPA. [ABSTRACT FROM AUTHOR]

Background: Children with autism spectrum disorder (ASD) show substantial variability in their language development. Language problems are highly prevalent in these children. In addition, the quality of early language abilities contributes to the overall development of these children and is highly predictive of their adult outcome. Yet, little is known about language development in children at risk of ASD during the first years of life. Aims: To compare early receptive language (RL) and expressive language (EL) development in children at risk of ASD and determine predictors of language development. Methods & Procedures: Developmental trajectories of RL and EL were investigated from 10 to 36 months of age in younger siblings of typically developing children (LR‐sibs, N = 30) and in younger siblings of children with ASD (HR‐sibs, N = 31) using the Mullen Scales of Early Learning. Furthermore, both child and demographic characteristics were examined as possible predictors of language development. Outcomes & Results: Both groups showed similar growth curves for RL and EL and the majority of the children showed average (within ±1.5 SD of the mean) or above‐average language abilities. Nevertheless, the mean growth of EL was lower and the variation in growth of both RL and EL was higher in HR‐sibs than in LR‐sibs. Furthermore, early child characteristics were predictive of language development in both groups. Yet, some child characteristics seemed to be of more importance in HR‐sibs than in LR‐sibs. Consequently, lower non‐verbal abilities at 10 months in both groups and a higher degree of ASD characteristics at 14 months in HR‐sibs may be indicative of difficulties in language development. Conclusions & Implications: HR‐sibs show more variation in their language development than LR‐sibs during the first 3 years of life. The majority of HR‐sibs, however, did not present with below‐average language abilities. Yet, early characteristics of ASD may be a red flag for difficulties in the language development of HR‐sibs.

Background: Late language emergence is a risk indicator for developmental language disorder. Parent‐implemented early language intervention programmes (parent programmes) have been shown to have positive effects on children's receptive and expressive language skills. However, long‐term effectiveness has rarely been studied. Additionally, little is known about which strategies parents learn to use after participating in parent programmes and whether this affects their child's language development. Aims: To evaluate medium‐ and long‐term effectiveness (1 and 2 years after inclusion) of a low‐dosage parent programme in a sample of late talkers (LTs) with an expressive language delay. Specifically, we investigated which strategies the parents learned to use in interaction with their child and which strategies were associated with child language growth over time. Methods & Procedures: This quasi‐experimental study with a longitudinal design included 24‐month‐old LTs. After the pre‐test, parents of children in the intervention group received a parent programme (n = 30), while parents of children in the comparison group received care as usual (n = 30). Children's language development was assessed using standardized language tests at pre‐test and two follow‐up tests at 36 and 48 months of age. Change in parental communicative behaviour was measured by a parent–child interaction observation measure, at pre‐test and follow‐up at 36 months of age. Outcomes & Results: At 36 months old, children in the parent programme group showed a significantly higher growth in expressive vocabulary than children in the comparison group. However, differences between the groups were not seen in the long‐term, at the 48‐month follow‐up. In contrast to parents in the comparison group, parents in the parent programme group changed their communicative behaviour positively in two domains: Interaction and Pressure on the child. However, no changes in the domains of Language Stimulation and Responsiveness were observed. Children's growth in expressive vocabulary and expressive syntax was associated with a decrease in the domain of Pressure. Conclusions & Implications: At 4 years of age, the majority of children in both groups achieved expressive vocabulary scores within the normal range. However, the mean score for expressive syntax in both groups remained below that of their peers, and 29% of the children still had expressive language scores below the mean range. Ongoing monitoring of LTs' language development is necessary in order to make decisions regarding the timing and nature of intervention. [ABSTRACT FROM AUTHOR]

Abstract: Background: Developmental language disorder (DLD) presents a considerable barrier for young adults to engage in further education and training. Early studies with young adults with DLD revealed poor educational achievement and lack of opportunities to progress in education. More recent studies have provided more positive findings. Relatively sparse data exist, however, on current cohorts and the factors that predict outcomes. Aims: To examine educational and employment outcomes in young adulthood in a sample of people with histories of DLD compared with an age‐matched peer group without DLD. We ask: How do educational pathways and early jobs compare between those with and without DLD? Are young adults with DLD receiving similar levels of income as their peers? To what extent are language and literacy abilities associated with outcomes? Methods & Procedures: Participants included 84 individuals with DLD (67% males) and 88 age‐matched peers without DLD (56% males). Participants were on average 24 years of age. They completed a battery of psycholinguistic, literacy and nonverbal skills assessments. Data were also collected on educational qualifications, current educational status, extent of educational support received, employment status, history and support, as well as current income. Outcomes & Results: Those with DLD obtained lower academic and vocational qualifications. Higher educational/vocational qualifications were associated with better language, better reading and higher performance IQ (PIQ). There were few differences between the two groups in terms of engagement with education, but the mean age at leaving education was significantly earlier in the participants with DLD. Substantially more participants with DLD reported receiving support or dispensation from their educational institution. There was no significant difference between groups in the proportion of young people currently employed, though a higher proportion of the age‐matched peers was in work full time. Participants with DLD were much more likely to be in non‐professional occupations. However, when examining pay in relation to types of occupation, the groups’ incomes were broadly comparable. Conclusions & Implications: At the group level, young people with a history of DLD more commonly have less skilled employment and more rarely achieve professional roles. At the individual level there is considerable variation with smaller but not trivial proportions of young adults with a history of DLD showing good educational and employment outcomes. There are positive aspects to early adult outcomes for some young people with a history of DLD. [ABSTRACT FROM AUTHOR]

Background There is increasing interest in examining the perspectives of parents of children with special educational needs (SEN). Exploring the view of parents of a child with language impairment (LI) or autism spectrum disorder (ASD) is particularly important because of their high prevalence, at over 30% of children with SEN in England, and the increasing evidence of overlapping profiles of their needs. Aims To examine the similarities and differences between the perspectives of parents of children with LI or ASD on three issues: (1) their child's educational progress, and their behavioural, emotional and social development; (2) the provision made to support their child's education and meet their SEN; and (3) their own involvement in decision-making about provision for their child. Methods & Procedures The parents of 129 children with LI ( n = 76) or ASD ( n = 53) were interviewed using a semi-structured protocol that gathered both quantitative data (parent ratings) and qualitative, in-depth explorations of their perspectives. Outcomes & Results There were no significant differences between the perspectives of parents of children with LI and parents of children with ASD with respect to their child's educational progress; the provision made to meet their child's educational needs; or their involvement in decision-making during the statutory assessment procedure, including the determination of a statement of SEN, and the current provision made by their child's school. Both parent groups were generally positive about these but parents of children with ASD were more concerned about their child's peer relationships. Parents whose child attended a mainstream school with a specialist resource tended to be more positive about the provision made than parents whose child was included individually into a mainstream school. Conclusions & Implications Although previous research indicates that parents of children with ASD are overrepresented among those who express dissatisfaction with the provision made to meet their child's needs, this study indicates high levels of satisfaction and overlap between the perspectives of parents of children with LI or ASD regarding their child's educational progress and their own involvement in decision-making about the child's provision. The findings indicate the importance for policy and practice of focusing on identified needs rather than diagnostic category; and the importance of practitioners and administrators engaging meaningfully with parents in collaborative decision-making.

Background The prevalence of speech-language impairments in children have been estimated for several languages, primarily in developed countries. However, prevalence data is lacking for developing countries, such as Nepal. Aims (1) To obtain teacher estimates of incidence and overall prevalence of speech-language impairments and its subtypes as a function of gender, age and grade level; and (2) to validate the screening instrument on Nepalese children. Methodology The adapted teachers' screening instrument, namely adapted Teachers' Speech and Language Referral Checklist (a-TSLRC), was administered in 2776 (690 and 2086) primary school children aged 5;00-11;11 years (mean = 8;11 years). The screening was conducted at four different points in time, i.e. Incidences I and II, and each incidence consisted of a testing and a retesting phase. Prior to this, teachers were trained in forum meetings, and an information sheet containing an overview of speech-language impairments, and guidelines/criteria for marking the occurrence of speech-language impairments in the TSLRC were disseminated. Outcomes & Results Overall prevalence of speech-language impairments in children was estimated as 8.11%. Specifically, overall speech problems were estimated as 4.68%, and language problems as 8.0%. Additionally, the prevalence by subtypes of speech-language impairments as categorized in the TSLRC were reported to be 2.95% for an articulation/phonological problems, 2.09% for stuttering, 3.42% for a voice problems, 4.97% for a receptive language problems and 7.74% for an expressive language problems. The internal consistency among items was sufficient and a good intra-rater reliability was obtained. Conclusions & Implications The study indicates that the overall results of speech-language impairments in children via the adapted in-Nepalese criterion-referenced instrument are supported by international studies. In addition, justifiable reliability and validity was obtained. Therefore, based on these overall evidence, this instrument can be useful for the screening of speech-language impairments in primary school children in Nepal. [ABSTRACT FROM AUTHOR]
