Titre : Predictors of longer-term development of expressive language in two independent longitudinal cohorts of language-delayed preschoolers with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Vanessa H. BAL, Auteur ; Megan FOK, Auteur ; Catherine LORD, Auteur ; Isabel M SMITH, Auteur ; Pat MIRENDA, Auteur ; Peter SZATMARI, Auteur ; Tracy VAILLANCOURT, Auteur ; Joanne VOLDEN, Auteur ; Charlotte WADDELL, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Terry BENNETT, Auteur ; Eric DUKU, Auteur ; Mayada ELSABBAGH, Auteur ; Stelios GEORGIADES, Auteur ; Wendy J.

Index. décimale : PER Périodiques Résumé : BACKGROUND: Studies estimate that 30% of individuals with autism are minimally verbal. Understanding what factors predict longer-term expressive development in children with language delays is critical to inform identification and treatment of those at-risk for persistent language impairments. The present study examined predictors of expressive language development in language-delayed preschoolers followed through later school-age and young adulthood. METHODS: Children using single words or less on the Autism Diagnostic Observation Schedule (ADOS) at approximately 3 years old were drawn from the Early Diagnosis (EDX) and Pathways in ASD longitudinal cohorts. Age-3 predictors of Age-19 ADOS language level were identified using Classification and Regression Trees (CART) in the EDX sample. Linear mixed models examined the effects of CART-identified predictors on Vineland expressive communication (VExp) trajectories from Age-3 to Age-19. The same linear mixed models were examined in the Pathways sample, identifying predictors of VExp from ages 3 to 10.5 years. RESULTS: Significantly delayed fine motor skills (T-score < 20) was the strongest CART predictor of Age-19 language. In the linear mixed models, time, Age-3 fine motor skills and initiation of joint attention (IJA) predicted VExp trajectories in the EDX sample, even when controlling for Age-3 visual receptive abilities. In the Pathways sample, time and Age-3 fine motor skills were significant predictors of VExp trajectories; IJA and cognitive skills were not significant predictors. CONCLUSIONS: Marked deficits in fine motor skills may be a salient proxy marker for identifying language-delayed children with ASD who are at risk for persistent language impairments. This finding adds to the literature demonstrating a relation between motor and language development in ASD. Investigating individual skill areas (e.g., fine motor and nonverbal problem-solving skills), rather than broader indices of developmental level (e.g., nonverbal IQ) may provide important cues to understanding longer-term language outcomes that can be targeted in early intervention.

ROGERS, Auteur ; Wendy J. UNGAR, Auteur Année de publication : 2022 Article en page(s) : p.5322-5341 Langues : Anglais (eng) Mots-clés : Child, Preschool Humans Autism Spectrum Disorder/therapy Autistic Disorder/diagnosis/therapy Canada Early Intervention, Educational/methods Feasibility Studies Parents Quality of Life Autism Community-based Feasibility Parent coaching Preemptive intervention Press and were used in this project. No other authors declare a conflict of interest. Index. décimale : PER Périodiques Résumé : A randomized feasibility trial of a parent coaching (PC) intervention was conducted across 16 community agencies in a Canadian province. Parents of toddlers with suspected autism were assigned to either a PC group (n=24) or an enhanced community treatment (ECT) group (n=25). PC participants received 24Â weeks of coaching support from community service providers trained in the project. Children in both groups also received available community services and supplementary materials. PC children made significantly greater gains in word understanding and PC parents had significantly higher quality of life, satisfaction, and self-efficacy scores. Results are discussed in terms of the challenges of conducting feasibility studies in community settings and the lessons learned in the project.

Data examining participant characteristics, study methodology, outcomes, and analysis were systematically extracted.Results: Eleven SSRD parent-training intervention studies examining 44 participants with ASD were included. Overall, the studies were of moderate quality and reported increases in parent skills and child language and communication outcomes.Interpretation: The results supported by improvement rate difference (IRD) analysis indicated several interventions demonstrated positive effects for both parent and child outcomes. However, limited generalization and follow-up data suggested only one intervention demonstrated parents’ accurate and ongoing intervention implementation beyond training.

Children diagnosed with autism spectrum disorder are often characterized as having 'reactive' and 'negative' temperaments when compared to same-aged peers with or without disabilities, which can negatively impact the development of adaptive functioning skills but little is known about variations of temperament between individual children diagnosed with autism spectrum disorder. This study aimed to (a) explore the variation of individual temperament traits within a sample of school-aged children with autism spectrum disorder to determine whether subgroups with similar trait profiles emerge and (b) examine whether temperament influences the relationship between autism symptoms and adaptive functioning outcomes. Results from our dataset suggest that children diagnosed with autism spectrum disorder fit under two profiles: 'even' and 'reactive'. Furthermore, our analysis shows that temperament can influence the impact of increasing symptom severity on adaptive functioning skills in children with autism spectrum disorder. Study findings highlight the importance of considering temperament when trying to understand the individual differences that influence the development of functioning and developmental outcomes in children with autism spectrum disorder.
