Adaptive skill trajectories in infants with fragile X syndrome contrasted to typical controls and infants at high risk for autism / Kelly E. CARAVELLA in Research in Autism Spectrum Disorders, 40 (August 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 40 (August 2017) . - p.1-12 Titre : Adaptive skill trajectories in infants with fragile X syndrome contrasted to typical controls and infants at high risk for autism Type de document : Texte imprimé et/ou numérique Auteurs : Kelly E. CARAVELLA, Auteur ; Jane E. ROBERTS, Auteur Article en page(s) : p.1-12 Langues : Anglais (eng) Mots-clés : Adaptive behavior  Fragile X syndrome  Infancy  Autism infant siblings Index. décimale : PER Périodiques Résumé : AbstractBackground Adaptive behaviors are essential for optimal outcomes and independence in individuals with developmental disabilities. This study examined longitudinal trajectories of adaptive behavior in infants with fragile X syndrome (FXS), compared to typical development (TD) and infant siblings of children diagnosed with autism (ASIBs). Method Participants included 76 male infants (FXS = 25, ASIBs = 27, TD = 24) assessed up to 4 times between 6 and 24 months of age for a total of 215 assessments of adaptive behavior. A sample of 12 females with FXS was included for a comparative sex analysis. Results Results indicate that infant males with FXS displayed lower initial adaptive behavior across all domains that emerged by 9 months-of-age with slower growth rates than both comparison groups. A flat profile across the domains at 24 months was evident. Increased severity of autism symptoms was related to reduced adaptive skills at 24 months-of-age. Females with FXS displayed higher scores than males on the Socialization and Motor domains and equivalent scores on the Communication and Daily Living domains at 9 months-of-age with different rates of growth across domains. Conclusions This is the first study to provide evidence of etiological specificity in adaptive behavior profiles during infancy across two populations at high risk for ASD. These findings support targeted adaptive behavior interventions in young children with FXS beginning as early at 9 months of age to reduce identified deficits and the cascading impacts of these early impairments.

Spatial and temporal analysis of postural control in children with high functioning Autism Spectrum Disorder / Nathalie GOULÈME in Research in Autism Spectrum Disorders, 40 (August 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 40 (August 2017) . - p.13-23 Titre : Spatial and temporal analysis of postural control in children with high functioning Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Nathalie GOULÈME, Auteur ; Isabelle SCHEID, Auteur ; Hugo PEYRE, Auteur ; Anna MARUANI, Auteur ; Julia CLARKE, Auteur ; Richard DELORME, Auteur ; Maria Pia BUCCI, Auteur Article en page(s) : p.13-23 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Children  Postural control  Wavelet transformation  Sensorial inputs Index. décimale : PER Périodiques Résumé : AbstractBackground Children with autism spectrum disorders (ASD) have poor postural stability. The objective of our study was to explore further postural capabilities in ASD children by measuring spatial as well as temporal displacement of the center of pressure using wavelet analysis. Method Thirty children with ASD (12.1 ± 2.9 years) and 30 sex-, age- and IQ-matched typically developing children participated in the study. We recorded postural control using Multitest, also called Balance Quest, Equilibre from Framiral® in three viewing conditions (eyes open, eyes closed and with perturbed vision) and in two postural conditions (stable and unstable). Results Our results show that children with ASD displayed a deficit in postural stability in comparison with typically developing children, especially when sensory inputs are not all available. Conclusion Such poor postural control in children with ASD could be due to both an impairment in using sensorial inputs appropriately and a deficit in the ability to compensate for sensorial changes.

Investigating the factor structure of the Child Behavior Checklist in a large sample of children with autism spectrum disorder / Kristen MEDEIROS in Research in Autism Spectrum Disorders, 40 (August 2017)

MAZUREK, Auteur ; Stephen M. KANNE, Auteur Article en page(s) : p.24-40 Langues : Anglais (eng) Mots-clés : Child behavior checklist  Autism spectrum disorder  Construct validity  Factor analysis Index. décimale : PER Périodiques Résumé : AbstractBackground Autism spectrum disorder (ASD) is characterized by core impairments in social communication and restricted and repetitive behaviors, with high rates of co-occurring emotional and behavioral problems. The Child Behavior Checklist (CBCL) is one of the most widely accepted rating scales used to assess childhood emotional and behavioral problems, and it has been used in many large-scale studies of children with ASD. However, it is not known whether the previously established factor model sufficiently accounts for symptom patterns in children with ASD. Method We conducted two Confirmatory Factor Analyses for each of the two versions of the CBCL (ages 1.5–5 and ages 6–18) in a large sample of children with ASD: one on the established measurement model and one on the structural model produced from an Exploratory Factor Analyses. We used several model fit indices to determine the best fitting model. Results We found that the established CBCL factor structure was the best fitting model for young children with ASD, but not for older children with ASD. Conclusions Models produced from Exploratory Factor Analyses provided evidence that the underlying behavioral constructs measured by the CBCL for ages 6–18 are different in children with ASD than among the typically developing sample. The results of this study have implications regarding how the CBCL should be interpreted in children with ASD.

How are parental reactions to children’s emotions linked with Theory of Mind in children with Autism Spectrum Disorder? / Stéphanie MAZZONE in Research in Autism Spectrum Disorders, 40 (August 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 40 (August 2017) . - p.41-53 Titre : How are parental reactions to children’s emotions linked with Theory of Mind in children with Autism Spectrum Disorder? Type de document : Texte imprimé et/ou numérique Auteurs : Stéphanie MAZZONE, Auteur ; Nathalie NADER-GROSBOIS, Auteur Article en page(s) : p.41-53 Langues : Anglais (eng) Mots-clés : Reactions  Emotions  Theory of mind  Autism spectrum disorders  Socialization  Beliefs  Mental states Index. décimale : PER Périodiques Résumé : AbstractBackground Based on the model of ‘Parental Socialization of Emotions’ (Eisenberg, Cumberland, & Spinrad, 1998), these studies examined the profiles of parental reactions to their children’s emotions and the relation between these reactions and their ASD children’s ToM abilities. They could help identify protective versus risk factors in their ToM development. Method The participants in Study 1 included 29 mothers and 29 fathers of ASD children (26 boys and 3 girls). In Study 2, 39 mothers and 31 fathers and their ASD children participated. In both studies, mothers and fathers independently completed a questionnaire about their reactions to their children’s emotions. In Study 2 only, children’s ToM abilities were assessed by means of direct measures and a questionnaire completed by parents. Results The results indicated that mothers displayed more encouragement and less minimizing responses to their ASD children’s negative emotions than fathers. For both maternal and paternal model analysed by stepwise regressions, the results highlighted specific links between each parent’s reactions and children’s ToM abilities that varied according to mental states. These findings suggested that parental reactions which help the children to understand how they can solve problems are protective factors, while parental reactions which deprive children of an opportunity to explore their feelings are risk factors. Conclusion These studies provide new information about how parental reactions to children’s emotions could socialise ASD children’s ToM abilities better; this could be useful for adapting parental support programmes.
