Titre : The reach-to-grasp movement in infants later diagnosed with autism spectrum disorder: a high-risk sibling cohort study Type de document : Texte imprimé et/ou numérique Auteurs : Lori-Ann R. SACREY, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Susan E. BRYSON, Auteur ; Jessica BRIAN, Auteur ; I. M. SMITH, Auteur Année de publication : 2018 Article en page(s) : 41 p. Langues : Anglais (eng) Mots-clés : Autism Autism spectrum disorder Baby siblings Infant siblings Motor Motor skills Reaching Index. décimale : PER Périodiques Résumé : BACKGROUND: Although autism spectrum disorder (ASD) is characterized by impairments in social communication and the presence of repetitive behavior and/or restricted interests, there is evidence that motor impairments may be a contributing factor to the ASD phenotype. The purpose of this study was to examine the motor act of reaching-to-grasp in children at high risk (HR; with an older sibling diagnosed with ASD) and low-risk (LR; no family history of ASD) for ASD. METHODS: Children were compared for differences in reaching-to-grasp based on sibling status and diagnostic outcome. Children were enrolled between 6 and 12 months of age and the reach-to-grasp movement was scored at 6, 9, (where available) 12, 15, 18, 24, and 36 months of age using the qualitative Skilled Reaching Rating Scale to determine the presence of any group-, age-, or sex-related differences in the mechanics of the reach-to-grasp movement using a Mixed Models analysis. At 36 months, all children underwent a gold-standard diagnostic assessment, which resulted in three outcome groups: HR children diagnosed with ASD (HR-ASD; n = 10), HR children not diagnosed with ASD (HR-N; n = 10), and low-risk children not diagnosed with ASD (LR; n = 10). RESULTS: The group of children who were later diagnosed with ASD (HR-ASD group) showed higher (worse) total scores on the reach-to-grasp movement, as well as higher scores on the components of Orient, Lift, and Pronate compared to children in the LR and HR-N groups. CONCLUSIONS: Our results support the growing literature indicating that children who are later diagnosed with ASD show impaired early motor performance. These results highlight the importance of early surveillance of children who are at elevated risk for ASD, and early initiatives should focus on early signs of the phenotype, including both movement and sensory differences (prodromal signs) prior to the emergence of diagnostic characteristics.

Titre : The Role of Prenatal, Obstetric and Neonatal Factors in the Development of Autism Type de document : Texte imprimé et/ou numérique Auteurs : Linda DODDS, Auteur ; Deshayne B. FELL, Auteur ; Sarah SHEA, Auteur ; B. Anthony ARMSON, Auteur ; Alexander C. ALLEN, Auteur ; Susan E. BRYSON, Auteur Année de publication : 2011 Article en page(s) : p.891-902 Langues : Anglais (eng) Mots-clés : Autism Cohort Prenatal Pregnancy Neonatal Epidemiology Index. décimale : PER Périodiques Résumé : We conducted a linked database cohort study of infants born between 1990 and 2002 in Nova Scotia, Canada. Diagnoses of autism were identified from administrative databases with relevant diagnostic information to 2005. A factor representing genetic susceptibility was defined as having an affected sibling or a mother with a history of a psychiatric or neurologic condition. Among 129,733 children, there were 924 children with an autism diagnosis. The results suggest that among those with low genetic susceptibility, some maternal and obstetric factors may have an independent role in autism etiology whereas among genetically susceptible children, these factors appear to play a lesser role. The role of pre-pregnancy obesity and excessive weight gain during pregnancy on autism risk require further investigation.

BRYSON, Auteur Article en page(s) : p.899-912 Langues : Anglais (eng) Mots-clés : autism spectrum disorder toddlers high-risk early intervention parent-mediated caregiver-mediated pivotal response treatment communication smiling Index. décimale : PER Périodiques Résumé : The Social ABCs is a parent-mediated intervention for toddlers with suspected or confirmed autism spectrum disorder (ASD). We undertook a multi-site pilot study to evaluate feasibility and acceptability, and to identify trends in child and parent behavior to inform future research using a larger sample and a rigorous research design. The program involved 12 weeks of parent coaching, followed by 12 weeks' implementation, and 3-month follow-up assessment for 20 parent-toddler dyads (age range: 12–32 months). Parents successfully learned the techniques and rated the intervention as highly acceptable. Paired samples t-tests revealed significant gains in children's functional communication (responsivity, initiations), and language gains (age-equivalents on standardized measures) commensurate with typical developmental rates. Significant increases in shared smiling and social orienting also emerged, but were attenuated at follow-up. Parents' fidelity was positively associated with child responsivity. Training parents as mediators is a feasible and highly acceptable approach that provides a potentially cost-effective opportunity for intensive intervention at a very young age at the first signs of ASD risk. Child and parent gains in several key variables demonstrate the promise of this intervention.

The results indicate significant differences between NB and NS in utilization of services and costs to families, public sector and society. Differences can be attributed to variation in EIBI delivery models and may also be influenced by differences in diagnostic assessment practices. The study results provide resource utilization rates and costs which could be used in future economic evaluations and to inform policy making to improve outcomes for children with ASD.

A confirmatory factor analysis was used to examine six competing structural models. Spearman’s rank order correlations were calculated to examine the associations between factor scores and variables of interest. The 3- and 5-factor models were selected as preferable on the basis of fit statistics and parsimony. For both models, the strongest correlations were with problem behavior scores on the Child Behavior Checklist and repetitive behavior scores on the ADI-R. Developmental index standard scores were not correlated with factors in either model. The results confirm the utility of the RBS-R as a measure of repetitive behaviors in young children with ASD.
