Continuity of trajectories of autism symptom severity from infancy to childhood / Martina FRANCHINI in Journal of Child Psychology and Psychiatry, 64-6 (June 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-6 (June 2023) . - p.895-906 Titre : Continuity of trajectories of autism symptom severity from infancy to childhood Type de document : Texte imprimé et/ou numérique Auteurs : Martina FRANCHINI, Auteur ; Isabel M.

Methods Developmental trajectories of early signs were examined in a cohort of siblings of children diagnosed with ASD (n =?502) from 6 to 18?months using the Autism Observation Scale for Infants (AOSI), and from 18?months to 5-7?years using the Autism Diagnostic Observation Schedule (ADOS). Diagnostic outcomes for ASD at age 3 confirmed diagnosis for 137 children. We further analyzed the conditional probability of a switch from a trajectory measured with the AOSI to a trajectory measured with the ADOS as well as predictors from age 6 months. Results We derived three early trajectories of behavioral signs (''Low,'' ''Intermediate,'' and ''Increasing'') from 6 to 18?months using the AOSI. We then derived three similar, distinct trajectories for the evolution of symptom severity between 18 and 60-84?months of age (Low, Intermediate, Increasing) using the ADOS. Globally, the Low trajectory included children showing fewer ASD signs or symptoms and the Increasing trajectory included children showing more severe symptoms. We also found that most children in the Low AOSI trajectory stayed in the corresponding ADOS trajectory, whereas children in an Increasing AOSI trajectory tended to transition to an Intermediate or Increasing ADOS trajectory. Developmental measures taken at 6 months (early signs of ASD, Fine Motor, and Visual Reception skills) were predictive of trajectory membership. Conclusions Results confirm substantial heterogeneity in the early emergence of ASD signs in children at increased likelihood for ASD. Moreover, we showed that the way those early behavioral signs emerge in infants is predictive of later symptomatology. Results yield clear clinical implications, supporting the need to repeatedly assess infants at increased likelihood for ASD as this can be highly indicative of their later development and behavior.

Early trajectories and moderators of autistic language profiles: A longitudinal study in preschoolers / Michel GODEL ; Martina FRANCHINI ; Fiona JOURNAL ; Nada KOJOVIC ; Marie SCHAER in Autism, 28-12 (December 2024)  

Public ISBD [article]  inAutism > 28-12 (December 2024) . - p.3043-3062 Titre : Early trajectories and moderators of autistic language profiles: A longitudinal study in preschoolers Type de document : Texte imprimé et/ou numérique Auteurs : Michel GODEL, Auteur ; Martina FRANCHINI, Auteur ; Fiona JOURNAL, Auteur ; Nada KOJOVIC, Auteur ; Marie SCHAER, Auteur Article en page(s) : p.3043-3062 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  cluster analysis  early intervention  Early Start Denver Model  moderators  precision medicine  prognosis Index. décimale : PER Périodiques Résumé : Both expressive and receptive language difficulties in autism emerge early and significantly have an impact on social functioning and quality of life. Despite their wide heterogeneity, autistic language abilities can be stratified into three distinct profiles. Language unimpaired exhibit near-typical verbal performance, language impaired show significant alterations in language structure, and minimally verbal display limited verbal abilities. However, little is known about the early trajectories and moderators specific to each profile. Here, we used a longitudinal sample of 286 preschoolers with autism and 85 typically developing (aged 1.5-5.7 years old), yielding 1164 visits. Our cluster analysis replicated the three well-established autistic language profiles (language unimpaired, n = 86; language impaired, n = 85; minimally verbal, n = 44) and revealed their specific early trajectories in expressive vocabulary, syntax, and pragmatics. At age 2.4, non-verbal cognition moderated the participants' attribution to each language profile. Moreover, early stereotyped language specifically moderated the later verbal performance of language unimpaired participants, while the language outcome of language impaired participants was moderated by early intensive behavioral intervention. In conclusion, we provided a fine-grained description of language acquisition trajectories and moderators of autistic language profiles in a longitudinal sample exposed to French language, paving the way toward personalized medicine to autistic language difficulties. Lay Abstract Language development can greatly vary among autistic children. Children who struggle with language acquisition often face many challenges and experience lower quality of life. However, little is known about the early language trajectories of autistic preschoolers and their moderators. Autistic language can be stratified into three profiles. Language unimpaired experience little to no language difficulties; language impaired show significant difficulties in language; minimally verbal never develop functional language. In this study, we used a longitudinal sample of preschoolers with autism and with typical development (aged 1.5-5.7?years). We replicated the three language profiles through a data-driven approach. We also found that different factors modulated the language outcome within each group. For instance, non-verbal cognition at age 2.4 moderated the participants' attribution to each language profile. Moreover, early intervention moderated verbal outcome in the language impaired profile. In conclusion, we provided a detailed description of how autistic preschoolers acquire language, and what factors might influence their trajectories. Our findings could inspire more personalized intervention for early autistic language difficulties.

Early trajectories of motor skills in infant siblings of children with autism spectrum disorder / James W. PATTERSON in Autism Research, 15-3 (March 2022)

SMITH, Auteur Article en page(s) : p.481-492 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Delays in motor development are not considered a core feature of autism spectrum disorder (ASD). Yet, recent studies of infant siblings of children with ASD suggest that early delays in motor skills may be associated with later delays in developmental areas considered to be core features of an ASD diagnosis. While these studies demonstrate the longitudinal association between core features and motor delays observed at single time points, there is considerable interest in studying the trajectories of motor development over the first 3?years of life. To accomplish this, we investigated early trajectories of motor development in a cohort of 499 infant siblings of children with ASD and 176 children with no family history of ASD. Data for the current study were drawn from the prospective, multi-site, Canadian Infant Sibling Study. We evaluated trajectories of fine and gross motor development over the first 3?years using group-based trajectory modeling. Our results show that membership for both fine and gross motor trajectory groups was related to expressive language skills, receptive language skills, ASD symptom severity scores, and diagnostic classification at age 3. These results provide evidence that the trajectory of a child's early motor development may have important prognostic implications in ASD.

Phenotyping variability in early socio-communicative skills in young children with autism and its influence on later development / Fiona JOURNAL in Autism Research, 17-10 (October 2024)  

Public ISBD [article]  inAutism Research > 17-10 (October 2024) . - p.2030-2044 Titre : Phenotyping variability in early socio-communicative skills in young children with autism and its influence on later development Type de document : Texte imprimé et/ou numérique Auteurs : Fiona JOURNAL, Auteur ; Martina FRANCHINI, Auteur ; Michel GODEL, Auteur ; Nada KOJOVIC, Auteur ; Kenza LATRÈCHE, Auteur ; Stefania SOLAZZO, Auteur ; Maude SCHNEIDER, Auteur ; Marie SCHAER, Auteur Article en page(s) : p.2030-2044 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  cluster analysis  deep phenotyping  joint attention  nonverbal communication  phenotype  trajectories Index. décimale : PER Périodiques Résumé : Abstract Children with autism spectrum disorder (ASD) often face challenges in early social communication skills, prompting the need for a detailed exploration of specific behaviors and their impact on cognitive and adaptive functioning. This study aims to address this gap by examining the developmental trajectories of early social communication skills in preschoolers with ASD aged 18?60?months, comparing them to age-matched typically developing (TD) children. Utilizing the early social communication scales (ESCS), the research employs a longitudinal design to capture changes over time. We apply a principal component analysis (PCA) to ESCS variables to identify underlying components, and cluster analysis to identify subgroups based on preverbal communication profiles. The results reveal consistent differences in early social communication skills between ASD and TD children, with ASD children exhibiting reduced skills. PCA identifies two components, distinguishing objects-directed behaviors and social interaction-directed behaviors. Cluster analysis identifies three subgroups of autistic children, each displaying specific communication profiles associated with distinct cognitive and adaptive functioning trajectories. In conclusion, this study provides a nuanced understanding of early social communication development in ASD, emphasizing the importance of low-level behaviors. The identification of subgroups and their unique trajectories contributes to a more comprehensive understanding of ASD heterogeneity. These findings underscore the significance of early diagnosis, focusing on specific behaviors predicting cognitive and adaptive functioning outcomes. The study encourages further research to explore the sequential development of these skills, offering valuable insights for interventions and support strategies.
