Health-related quality of life in these two groups remains poorly understood. Furthermore, studies have typically relied on reports from caregivers and teachers rather than using self-report measures. The aim of the current study is to compare the levels and profiles of self-reported health-related quality of life of children with developmental language disorders and children with autism spectrum disorder. Methods Participants comprised 114 7-to-13-year-old children with developmental language disorders (n = 63) and children with autism spectrum disorder (n = 51) attending mainstream school. Self-reported health-related quality of life was measured using the KIDSCREEN-52. We also collected standardised measures of receptive language, autism spectrum disorder symptoms, nonverbal IQ and emotional and behavioural problems. Results Children with developmental language disorders reported health-related quality of life commensurate with normative ranges, except for 2 of the 10 dimensions; the Moods and Emotions domain and the Social acceptance/bullying domain, which were below norms. Children with autism spectrum disorder reported significantly lower health-related quality of life compared to norms and the developmental language disorders group. However, when the effects of non-verbal ability and language – on which the groups were not matched – were covaried most group differences fell to non-significance or disappeared. Child characteristics showed few associations with dimensions of health-related quality of life across groups. Conclusions Children with autism spectrum disorder may be particularly vulnerable to poorer health-related quality of life and the relevant professionals need to be aware of this. Children with developmental language disorders exhibit a profile of health-related quality of life more in-line with average ranges. However, certain domains warrant monitoring and may benefit from intervention. Many of the between-group differences in self-reported health-related quality of life disappeared when non-verbal and language ability were covaried, though neither of the covariates was systematically related to scores. Other within-child factors such as emotional understanding and competence should be explored in future studies. Implications Further research into child and contextual factors may elucidate risk or protective factors for health-related quality of life in children with neurodevelopmental disorders.","PeriodicalId":36716,"journal":{"name":"Autism and Developmental Language Impairments","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2396941519851225","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43407078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Method Using a systematic review of the current literature in language regression and a purposive sampling of language theories, hypotheses for the cause of language regression are discussed. Results The following hypotheses were developed based on the reviewed theories of word learning: (a) Initial first words were not true words, but instead were protowords; (b) fast mapped forms never progressed to truly learned words; (c) initial first words were echoed productions of heard words; (d) the described regression is actually a maintenance of previous developmental levels with increasing chronological age. Conclusions It is possible that individuals with autism spectrum disorder are not “losing” words, but instead are not progressing in their ability to learn and use new words. Early word learning in typically developing children is seemingly similar to early development in individuals with autism spectrum disorder; however, the ability to expand from early “intermediate words” to expansive vocabularies, word combinations, and morphological variations is impeded.

Smith, Fiona Davidson","doi":"10.1177/2396941519864084","DOIUrl":"https://doi.org/10.1177/2396941519864084","url":null,"abstract":"Background and aims We introduce the Assessment of Phase of Preschool Language (APPL), a rating form that characterizes children’s language according to a well-established framework recommended by Tager-Flusberg et al. (2009). The language benchmarks framework defines children’s language as falling at one of the Pre-verbal, First Words, Word Combinations, Sentences, or Complex Language phases for phonology, vocabulary, grammar, pragmatics, and overall language. The APPL is a flexible assessment tool that allows assessors to determine language phase using a range of assessment sources: natural language samples, standardized measures, and/or parent rating forms. Using the APPL, we examined language profiles in four- and five-year-olds with autism spectrum disorder and explored language development during a community-based Naturalistic Developmental Behavioral Intervention program. Methods Community speech-language pathologists completed the APPL with 95 four- and five-year-olds at the beginning of the treatment. The APPL was re-administered after a mean of 10 months of intervention (SD = 2 months) for 46 of these children. Children received treatment for up to 15 h per week in their homes and/or community childcare centers. Pivotal Response Treatment was the main form of intervention. The Picture Exchange Communication System or other augmentative and alternative communication systems were also used with many pre-verbal children. Results At the beginning of intervention, the most common language phase was Word Combinations (44%), followed by Pre-verbal (26%), Sentences (20%), and then First Words (10%). Only 24% of children had even profiles (i.e. phonology, vocabulary, grammar, and pragmatics skills at the same level). Phonology was a common area of relative strength, and pragmatics was a common area of relative weakness. Ten months of intervention was associated with gains in overall language phase for 37% of children. Approximately half gained at least one phase in Grammar (57%), Vocabulary (51%), and Phonology (46%), while Pragmatics improved for 33%. Gains varied based on initial language phase. Inclusion of skills using augmentative and alternative communication enhanced interpretation of change during intervention. Conclusions Four- and five-year-olds with autism spectrum disorder in this sample tended to have uneven skills across expressive language domains. Community-based Naturalistic Developmental Behavioral Intervention was associated with gains in language phase in older preschoolers with autism spectrum disorder. Gains varied across language domains and were influenced by initial language phase. Implications The Assessment of Phase of Preschool Language is a useful tool to support consistent application of the language benchmarks framework. It is important to consider all language domains when characterizing language skills and treatment impact in children with autism spectrum disorder.","PeriodicalId":36716,"journal":{"name":"Autism and Developmental Language Impairments","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2396941519864084","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41886098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our first aim was to differentiate interventions using a developmental social pragmatic model from other developmental or naturalistic behavioral approaches. We applied explicit criteria outlining core features of developmental social pragmatic interventions to identify programs that use these core features. We then systematically reviewed studies examining the impact of developmental social pragmatic interventions in supporting (a) foundational social communication and language skills of preschool children with autism spectrum disorder and (b) caregiver interaction style. Additionally, we reviewed results exploring mediators and potential factors influencing children’s response to developmental social pragmatic interventions. Methods A multistep comprehensive search strategy was used to identify developmental social pragmatic treatments and studies examining their effectiveness for preschool children with autism spectrum disorder. The characteristics of each study and their outcomes were then reviewed, and a modified Critical Appraisal Skills Programme tool was used to evaluate rigor. Main contribution/Results Six interventions that met criteria to be classified as developmental social pragmatic are examined within this review. Ten studies of varying methodological rigor met criteria for inclusion and collectively reported on the outcomes of 716 preschool-aged children with autism spectrum disorder. All of the studies examined foundational communication outcomes and all but one reported positive outcomes for at least one of the measures. Seven studies examined language outcomes. While results were positive for language use within natural contexts, they were mixed for overall, receptive, and expressive language. Parents’ interaction styles significantly changed postintervention, namely in terms of increased responsiveness, synchronous behavior, use of affect, and decreased directiveness. Only two studies conducted formal mediation analysis and found that parent responsiveness and synchronous behavior were related to children’s positive response to treatment. Conclusions This review suggests that developmental social pragmatic treatments positively impact children’s foundational communication capacities (i.e. attention, social referencing, joint attention, initiation, reciprocity). Positive findings were not consistently found for supporting children’s language. Further, methodologically rigorous studies are needed to draw definitive conclusions. Additional research exploring components of developmental social pragmatic treatments that might mediate response to treatment is needed.

Previous research has found mixed results on the phonological awareness skills of children with autism spectrum disorders. Therefore, the purpose of the present study is to add to our understanding of phonological awareness in children with autism spectrum disorder by investigating residualized gains in phonological awareness skills over an academic year. Methods A total of 125 preschool (4- to 5-years old) children including 27 children with autism spectrum disorder, 28 children with language impairment, and 70 typically developing children were the focus of the present study. Participants in the current study represent a subset of participants from a larger study titled, Sit Together and Read. Children completed direct assessments in the beginning (fall) and end of school year (spring) on phonological awareness using the Test of Preschool Early Literacy. Results A one-way ANOVA compared the phonological awareness skills tasks (syllable/onset-rime, blending/elision, receptive/expressive) in the fall and the spring for each of the three groups (children with autism spectrum disorder, children with language impairment, children who are typically developing). In the fall and the spring, all of the analyses were found to be statistically significant. A Tukey HSD further indicated that children with autism spectrum disorder had significantly lower scores on all of the tasks at both time points compared to the typically developing peers. Children with autism spectrum disorder seem to make gains in phonological awareness tasks similarly to their typically developing peers for most of the phonological awareness tasks. Results from the final regression models indicated that children with autism spectrum disorder made gains similar to those of their typically developing peers for most phonological awareness tasks and that language skills predicted residualized gain for syllable, elision, and receptive tasks, as well as the total score when controlling for condition, IQ, and group status. Social skills were not a significant predictor for any of the tasks. Conclusions Three main findings emerged: (a) phonological awareness skills seem to be a deficit for children with autism spectrum disorder, (b) in general, autism status does not predict residualized gain in phonological awareness skills, and (c) oral language is a significant predictor of residualized gain in phonological awareness skills. Implication Early childhood educators should focus on providing high-quality instruction on phonological awareness for children with autism spectrum disorder and researchers should focus on investigating the effectiveness of phonological awareness interventions for children with autism spectrum disorder.","PeriodicalId":36716,"journal":{"name":"Autism and Developmental Language Impairments","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2396941518822453","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45955933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study involves college-aged students aged 16–19 years with Language Disorder and Word-Finding Difficulties and investigates whether progress in word finding following 1:1 semantic intervention is greater than progress during a baseline period as measured by a standardised test. Methods Twenty-five college-aged students (20 males and 5 females) with Language Disorder and Word-Finding Difficulties (aged 16;4–18;4 years) participated in a single baseline design study comparing progress on the Test of Adolescent and Adult Word Finding during an intervention period with progress during a baseline period of equal length. Intervention was focused on semantics of different words from those in the Test of Adolescent and Adult Word Finding and was delivered 1:1 by the participants’ usual Speech and Language Therapist, 30 minutes per week, for eight weeks. Results The participants made significant progress in raw score on the Test of Adolescent and Adult Word Finding during both the baseline (d = 1.4) and intervention (d = 2.5) periods, but progress during the intervention period was significantly greater than during the baseline period (d = 1.16). Individual data showed reliable change for five participants during the baseline period and for 20 participants during the intervention period. At the start of the study, all participants had standard scores below 85, but after intervention, 10/25 participants scored above 85. Conclusions Four hours of semantic intervention led to significantly greater gains on a standardised test of word finding than during a baseline period of equal length in 16–19 year olds with Language Disorder and Word-Finding Difficulties. The words in the standardised test had not been included in the intervention, indicating generalised gains.

This study investigated whether there is evidence that children with DLD use linguistic and EF resources to support their lexical and syntactic development. Three questions were addressed: (1) How do children with DLD develop in the domains of lexicon and syntax, and how does their development compare to TD controls? (2) To what extent do children with DLD show reciprocal relations between lexical and syntactic skills, and how does this compare to TD controls? (3) Is EF ability related to DLD children’s lexical and syntactic skills, and how does this compare to TD controls? Methods Data from 117 children (NDLD = 78; NTD = 39) were collected three times with yearly intervals. At time 1, the children were 5 or 6 years old. Standardized receptive vocabulary and sentence repetition tests measured lexicon and syntax, respectively. Nonverbal EF tasks tested selective attention, interference control and working memory. Cross-lagged analyses were conducted to determine the direction of relationships. Results Both groups showed stable lexical and syntactic growth. In children with DLD, but not in TD controls, syntactic skills predicted lexical skills. In the DLD group, EF predicted lexical skills. Reversely, in the TD group, lexical skills predicted EF. Conclusions The results of this study are consistent with the hypothesis that the lexical development of children with DLD is supported by both their verbal abilities in the domain of syntax and their nonverbal EF abilities.

Yet, little is known about the linguistic-pragmatic abilities of young children with DLD. Previous studies suggest that children with DLD are experiencing difficulties with idioms, sayings and slang expressions, often interpreting them in a literal or unconventional fashion. However, it is unclear whether this is caused by difficulties to make pragmatic inferences in general or whether it stems from their semantic abilities. We therefore investigated novel metaphor understanding in young children with and without DLD. Methods We assessed novel metaphor comprehension using a reference assignment task with 15 children with DLD diagnoses (ages 42–49 months) as well as typically developing peers matched on chronological age (n = 15) and on language (n = 15). Results Children with DLD performed worse than their age-matched peers but in a comparable manner to the (younger) language-matched typically developing children. Performance was not related to non-verbal intelligence in the children with DLD. Conclusion The findings indicate that young children with DLD have difficulties with metaphor comprehension but also suggest that these difficulties are in line with their general language difficulties and linked to their overall linguistic competence rather than reflecting additional specific issues with deriving pragmatic inferences. Implications Our study adds to a growing body of literature showing that children with low language abilities are also likely to display more difficulties in understanding figurative language independently of any other symptomatology of their clinical diagnosis. It also supports the argument that deficits in the pragmatic domain are a secondary impairment rather than a core deficit in children with DLD. Nonetheless, children with DLD do show difficulties in understanding metaphors. Understanding figurative language is necessary for everyday communication and should therefore be targeted alongside traditional treatments by clinicians treating children with DLD.","PeriodicalId":36716,"journal":{"name":"Autism and Developmental Language Impairments","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2396941518817229","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43976798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ireland","doi":"10.1177/2396941518821570","DOIUrl":"https://doi.org/10.1177/2396941518821570","url":null,"abstract":"Background and aims Facilitated Communication (FC) is a technique that involves a person with a disability pointing to letters, pictures, or objects on a keyboard or on a communication board, typically with physical support from a “facilitator”. Proponents claim that FC reveals previously undetected literacy and communication skills in people with communication disability. However, systematic reviews conducted up to 2014 reveal no evidence that the messages generated using FC are authored by the person with a disability. This study aimed to conduct a systematic review of the literature on FC published between 2014 and 2018 to inform the 2018 update of the 1995 American Speech-Language-Hearing Association Position Statement on FC. Method A systematic search was undertaken to locate articles about FC in English published in the peer reviewed literature since 2014; and to classify these according to the study design for analysis. Studies meeting the inclusion criteria were classified according to four categories of evidence: (a) quantitative experimental data pertaining to authorship, (b) quantitative descriptive data on messages produced using FC, (c) qualitative data, or (d) commentary material on FC. Main contribution In total, 18 studies met the inclusion criteria. There were no new empirical studies and no new descriptive quantitative studies addressing the authorship of messages delivered using FC. Three new qualitative studies qualified for inclusion; these did not first establish authorship. Of the 15 new commentary papers on FC located, 14 were critical and one was non-critical. The results could be used to inform the development or update of current position statements on FC held locally, nationally, and globally. Conclusion There are no new studies on authorship and there remains no evidence that FC is a valid form of communication for individuals with severe communication disabilities. There continue to be no studies available demonstrating that individuals with communication disabilities are the authors of the messages generated using FC. Furthermore, there is substantial peer-reviewed literature that is critical of FC and warns against its use. Implications FC continues to be contested in high profile court cases and its use promoted in school settings and workshops at university campuses in the US. Our empty systematic review will influence both clinical practice and future clinical guidance; most immediately the American Speech-Language-Hearing Association Position Statement on FC and any future guidance issued by the 19 associations worldwide with positions against FC.","PeriodicalId":36716,"journal":{"name":"Autism and Developmental Language Impairments","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2396941518821570","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42962665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
