Existing reports in autism do not emphasize subtypes of aggression, whereas distinguishing forms of aggression is commonplace in the typically developing literature. This study compared a sample of 121 children aged 3–20 years with autism spectrum disorders (ASD) to 244 children with other intellectual and developmental disabilities (IDD; age 4–21 years). Item- and subscale-level data from the Children's Scale for Hostility and Aggression: Reactive/Proactive (C-SHARP) were reported. Children with ASDs received higher ratings than those with IDD on several subscales tapping physical and reactive aggression. Within the ASD group, children with Asperger's disorder were rated significantly higher than children with autism on subscales tapping covert and verbal behaviors. Results indicate that at least some types of aggression were more common in children with ASDs than those with IDDs.

Predictors and Moderators of Parent Training Efficacy in a Sample of Children with Autism Spectrum Disorders and Serious Behavioral Problems / Cristan A. FARMER in Journal of Autism and Developmental Disorders, 42-6 (June 2012)

The intent-to-treat analyses were rerun with putative predictors and moderators. The Home Situations Questionnaire (HSQ) and the Hyperactivity/Noncompliance subscale of the Aberrant Behavior Checklist were used as outcome measures. Candidate predictors and moderators included 21 demographics and baseline measures of behavior. Higher baseline HSQ scores predicted greater improvement on the HSQ regardless of treatment assignment, but no other predictors of outcome were observed. None of the variables measured in this study moderated response to PT. Antipsychotic medication plus PT appears to be equally effective for children with a wide range of demographic and behavioral characteristics.

Repetitive Behavior and Restricted Interests in Young Children with Autism: Comparisons with Controls and Stability Over 2 Years / Lisa JOSEPH in Autism Research, 6-6 (December 2013)  

Public ISBD [article]  inAutism Research > 6-6 (December 2013) . - p.584-595 Titre : Repetitive Behavior and Restricted Interests in Young Children with Autism: Comparisons with Controls and Stability Over 2 Years Type de document : Texte imprimé et/ou numérique Auteurs : Lisa JOSEPH, Auteur ; Audrey THURM, Auteur ; Cristan A.

Previous studies have indicated that RRBs differentiate ASD from other developmental disorders and from typical development. This study examined the presentation of RRBs as reported on the Repetitive Behavior Scale-Revised, a caregiver report, in children with ASD [separated into autism and Pervasive Developmental Disorder-Not Otherwise Specified groups] compared with children with nonspectrum developmental delays or typical development. We examined the role of age, cognitive functioning, sex and social communication impairment as they relate to RRBs. The stability of RRBs in children with autism was also examined over the course of 2 years. Results of the study confirmed that the amount and type of RRBs differs by diagnosis. Age, cognitive functioning, sex and social-communication impairment were not significant correlates. Among children with autism, RRBs remained stable over time.

The ADOS Calibrated Severity Score: Relationship to Phenotypic Variables and Stability over Time / Stacy SHUMWAY in Autism Research, 5-4 (August 2012)  

Public ISBD [article]  inAutism Research > 5-4 (August 2012) . - p.267-76 Titre : The ADOS Calibrated Severity Score: Relationship to Phenotypic Variables and Stability over Time Type de document : Texte imprimé et/ou numérique Auteurs : Stacy SHUMWAY, Auteur ; Cristan A. FARMER, Auteur ; Audrey THURM, Auteur ; Lisa JOSEPH, Auteur ; David O. BLACK, Auteur ; Christine GOLDEN, Auteur Année de publication : 2012 Article en page(s) : p.267-76 Langues : Anglais (eng) Mots-clés : autism diagnostic observation schedule (ADOS)  autism spectrum disorders  severity  diagnosis Index. décimale : PER Périodiques Résumé : Measurement of the severity of autism at a single time point, and over time, is a widespread challenge for researchers. Recently, Gotham, Pickles, and Lord published a severity metric (calibrated severity scores; CSS) that takes into account age and language level and is based on raw total scores of the Autism Diagnostic Observation Schedule (ADOS), a standardized measure commonly used in autism diagnosis. The present study examined psychometric characteristics of the CSS compared to raw scores in an independent sample of 368 children aged 2 to 12 years with autism, pervasive developmental disorder-not otherwise specified (PDD-NOS), non-spectrum delay, or typical development. Reflecting the intended calibration, the CSS were more uniformly distributed within clinical diagnostic category and across ADOS modules than were raw scores. Cross-sectional analyses examining raw and severity scores and their relationships to participant characteristics revealed that verbal developmental level was a significant predictor of raw score but accounted for significantly less variance in the CSS. Longitudinal analyses indicated overall stability of the CSS over 12 to 24 months in children with autism. Findings from this study support the use of the CSS as a more valid indicator of autism severity than the ADOS raw total score, and extend the literature by examining the stability over 12 to 24 months of the CSS in children with ASD.
