Age of autism spectrum disorder diagnosis is associated with child's variables and parental experience / Ram A. MISHAAL in Research in Autism Spectrum Disorders, 8-7 (July 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-7 (July 2014) . - p.873-880 Titre : Age of autism spectrum disorder diagnosis is associated with child's variables and parental experience Type de document : Texte imprimé et/ou numérique Auteurs : Ram A. MISHAAL, Auteur ; Esther BEN-ITZCHAK, Auteur ; Ditza A. ZACHOR, Auteur Article en page(s) : p.873-880 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD)  Age of diagnosis  Social impairments  Restricted and repetitive behaviors  Developmental regression  Adaptive functioning  First born child Index. décimale : PER Périodiques Résumé : Abstract Early diagnosis of autism spectrum disorder (ASD) is highly important as it enables an early start to intervention. The current study examined familial (parental ages; education; having an older sibling) and child (gender; reported and observed autism symptoms severity; adaptive skills) related variables that might predict the age of ASD diagnosis. The study included 551 participants, age range 15–72 months, diagnosed with ASD who underwent comprehensive medical and behavioral assessment using standardized tests. Of the child's examined variables, the severity of the social interaction impairment reported by the parents and having a history of developmental regression was associated with an earlier age of ASD diagnosis. In contrast, the severity of the restricted and repetitive behaviors was associated with delayed age of ASD diagnosis. Vineland Adaptive Behavior Scales scores lower or higher than the group's mean (70 points) were associated with a relatively delayed age of ASD diagnosis. Of the familial variables, only having an older sibling was associated with an earlier diagnosis. Professionals should be aware that subtle signs of ASD, developmental delay and close to normal adaptive functioning might delay age of ASD diagnosis. Educating parents on “red flags” for ASD and periodic surveillance in early childhood are important.

Are special abilities in autism spectrum disorder associated with a distinct clinical presentation? / Esther BEN-ITZCHAK in Research in Autism Spectrum Disorders, 7-9 (September 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-9 (September 2013) . - p.1122-1128 Titre : Are special abilities in autism spectrum disorder associated with a distinct clinical presentation? Type de document : Texte imprimé et/ou numérique Auteurs : Esther BEN-ITZCHAK, Auteur ; Binet AVIVA, Auteur ; Ditza A. ZACHOR, Auteur Article en page(s) : p.1122-1128 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Special abilities  Autism severity symptoms  Adaptive skills  Head circumference percentile Index. décimale : PER Périodiques Résumé : Abstract Special abilities may be common in autism spectrum disorders (ASD). The aim of this study was to investigate the clinical presentation of ASD with special abilities. Special abilities were defined based on the Autism Diagnostic Interview-Revised (ADI-R). Based on a sample of 398 children, ages 2–7 years old with ASD, 112 with special skills were compared to an age- and gender-matched group without special abilities (n = 79). The examined measures included autism symptoms severity, adaptive behaviors and head circumference percentile. Children with ASD and special abilities seemed to exhibit significantly less impaired ASD symptoms in the social, communication and stereotyped behaviors and significantly better adaptive skills than individuals with ASD without special skills. Children with ASD and special abilities had a larger head circumference percentile than children without special abilities. Special abilities occurred in 28% of the study participants. Memory skills were the most frequently reported special ability, followed by musical, visuospatial and reading skills. The authors conclude that individuals with ASD and special abilities might represent a distinct ASD subgroup with milder clinical ASD presentation. Larger head circumference in ASD was previously associated with enhanced “local” connectivity which provides detailed information processing and therefore might be related to the appearance of special abilities.

Autism severity and motor abilities correlates of imitation situations in children with autism spectrum disorders / Ditza A. ZACHOR in Research in Autism Spectrum Disorders, 4-3 (July-September 2010)

This study examined whether imitation abilities are related to autism severity and to motor skills. Furthermore, the performance of children with ASD in four imitation situations (body movements and ‘action on objects’, using meaningful and non-meaningful tasks) was compared. Twenty-five children aged 32–51 months diagnosed with autism (23) and ASD (2) were evaluated for autism severity using the Autism Diagnosis Observation Schedule and for gross and fine motor skills using the Peabody Developmental Motor Scales. Controlling for cognitive level, imitation abilities in all four situations correlated significantly only with autism severity measures and mostly with socio-communication deficits. Motor abilities were below average and did not correlate with imitation abilities nor with autism severity. Comparison of the four imitation situations revealed that performances of meaningful actions were better than non-meaningful actions and imitation of ‘action on objects’ was better than imitation of body movements. The current research supports the fact that socio-communication deficits and not motor abilities are linked to imitation abilities in young children with autism.

Change in autism classification with early intervention: Predictors and outcomes / Esther BEN-ITZCHAK in Research in Autism Spectrum Disorders, 3-4 (October-December 2009)

Sixty-eight children diagnosed with autism, aged 18–35 months (M = 25.4, SD = 4.0) participated in the study. Children underwent comprehensive evaluations at pre-intervention time (T1) and after 1 year of intervention (T2). The evaluation included autism classification based on Autism Diagnosis Observation Schedule (ADOS) original algorithm, cognitive abilities (Mullen) and adaptive skills evaluation (Vineland). At T2, two groups were identified: the Unchanged group (n = 53) remained in the same autism classification and the Improved group (n = 15) changed classification to Autism Spectrum Disorder (ASD) (n = 13) or Off Spectrum (n = 2). The verbal domain scores at T1 was the only significant variable that distinguished the two groups. Specifically, the Improved group had better receptive language scores than the Unchanged group. The Improved group gained significantly more than the Unchanged group in all the outcome measures (cognitive, adaptive and reduction of stereotyped behaviors). Two distinct subtypes of autism were identified, one with stable autism symptomatology, poor verbal abilities and limited cognitive and adaptive gains, and a second type with better baseline verbal abilities and overall better response to intervention.

This study compared two intervention approaches, Eclectic-Developmental (ED) and Applied Behavioral Analysis (ABA) in very young children with autism/autism spectrum disorder (ASD). Nineteen children received ED intervention, using combination of methods. Twenty children received Applied Behavioral Analysis (ABA) intervention which used behavioral principles. Children in both groups were not significantly different in their autism severity, cognitive abilities and in socio-economic background at pre-intervention time. Change in the severity of autism symptoms was assessed by the Autism Diagnosis Observation Schedule (ADOS). The ABA group showed significantly greater improvements than the ED group at post-intervention time. Pre–post intervention differences in language and communication domain were significant only for the ABA group. Both groups showed significant improvement in reciprocal social interaction domain. However, the effect size was greater for the ABA group. Changes in diagnostic classification were noted in both groups but were more pronounced for the ABA group. Pre-treatment IQ scores were positively related to ADOS scores at pre- and post-intervention times, but not to progress over time. Behavioral intervention is more effective than eclectic approach in improving autism core symptoms in young children with autism.
