An examination of the reliability of a new observation measure for autism spectrum disorders: The autism spectrum disorder observation for children / Daniene NEAL in Research in Autism Spectrum Disorders, 7-1 (January 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-1 (January 2013) . - p.29-34 Titre : An examination of the reliability of a new observation measure for autism spectrum disorders: The autism spectrum disorder observation for children Type de document : Texte imprimé et/ou numérique Auteurs : Daniene NEAL, Auteur ; Johnny L. MATSON, Auteur ; Brian C. BELVA, Auteur Année de publication : 2013 Article en page(s) : p.29-34 Langues : Anglais (eng) Mots-clés : ASD-OC  Autism spectrum disorder  Reliability  Assessment Index. décimale : PER Périodiques Résumé : The autism spectrum disorder observation for children (ASD-OC) is a newly created 54-item observation measure for autism spectrum disorders (ASD). Due to the fact that many of the ASD observation measures currently available do not have established psychometric properties and require extensive time and training to administer, the ASD-OC seeks to address these issues. The purpose of this initial study was to investigate the reliability of the ASD-OC. The measure was administered to a sample of 114 children as part of an outpatient evaluation. In a subset of the sample, 26 children were rated by two independent clinicians after the same session. Interrater reliability was calculated using intraclass coefficients (ICC). Five items were removed after this interrater reliability analysis given poor reliability coefficients less than .40. Mean interrater reliability for each of the 49 retained items was good (i.e., .73). Interrater reliability for the scale as a whole was excellent (i.e., ICC = .96). Item analysis and internal consistency were investigated in the total sample (n = 114). Four items were removed from the scale because of little to no variance in scores. Forty-five items remained on the scale. The internal consistency of the ASD-OC as measured by Cronbach's alpha was excellent at .96. The ASD-OC proved to be a promising measure with robust reliability.

Convergent validity of the Autism Spectrum Disorders-Diagnostic Adult (ASD-DA) with the Pervasive Developmental Disorder/Autism subscale of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II) / Brian C. BELVA in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)

In order to further establish the validity of this measure, convergent validity of the ASD-DA was established by comparing ASD-DA total and subscales scores with the Pervasive Developmental Disorder/Autism (PDD/Autism) subscale score on the Diagnostic Assessment for the Severely Handicapped-II (DASH-II). Data was collected from 278 adults residing in two large supports and services centers in the southeastern region of the United States. The ASD-DA total scores and all subscale scores correlated with the PDD/Autism subscale score at the p < .001 level, further supporting the validity of the ASD-DA as a valid measure of autistic symptoms in adults with ID. The implications of these findings are discussed.

Feeding and sleep difficulties in toddlers with autism spectrum disorders / Alison M. KOZLOWSKI in Research in Autism Spectrum Disorders, 6-1 (January-March 2012)

Feeding and sleep difficulties are purportedly common within the ASD population, although the association between these problems and ASD symptomatology has rarely been addressed. The current study examined the feeding and sleep difficulties of 1747 toddlers who had a diagnosis of Autistic Disorder (n = 506), PDD-NOS (n = 522), or atypical development (n = 719) using the Baby and Infant Screen for Children with aUtIsm Traits-Part 2, a screening tool designed to identify comorbid difficulties of toddlers with ASD and/or atypical development. Individuals with Autistic Disorder were found to exhibit significantly more feeding and sleep difficulties than those with PDD-NOS, who in turn presented with more difficulties of this type than those with atypical development. While developmental quotient (DQ) was also related to feeding and sleep difficulties, DQ could not account for the differences between these groups.

The effects of informant age and education level on childhood ASD symptom endorsement / Megan A. HATTIER in Research in Autism Spectrum Disorders, 7-2 (February 2013)

The current study aimed to expand that research to include analysis of the relationship of maternal age and education level on mothers' ratings of their child's ASD by inspecting the total score on the Autism Spectrum Disorders ' Diagnostic for Children (ASD-DC). We investigated biological mothers' ratings of 73 children (5'16 years of age), all of who had ASD diagnoses. Informants were classified into one of three age groups ('34 years; 35'40 years; '41 years) and one of two education groups (high school graduate; university graduate). Following a two-way ANOVA, a significant interaction effect was found for informant age group and education level on total scores of the ASD-DC. Within the '41 age group, ratings of ASD increased (indicating greater impairment) as the informants' education level increased. A reverse trend was established in the other two age groups. Further findings and implications are discussed.
