Factor Analysis of the Childhood Autism Rating Scale in a Sample of Two Year Olds with an Autism Spectrum Disorder / E. MOULTON in Journal of Autism and Developmental Disorders, 49-7 (July 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-7 (July 2019) . - p.2733-2746 Titre : Factor Analysis of the Childhood Autism Rating Scale in a Sample of Two Year Olds with an Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : E.

This study investigated the factor structure of the CARS in a sample of 2-year-old children with DSM-IV-TR (American Psychiatric Association in Diagnostic and statistical manual of mental disorders, 4th edn. American Psychiatric Publishing, Washington, 2000) diagnoses of AD or PDD-NOS. Following a preliminary internal cross-validation, principal axis factor analysis was completed (N = 282). The results indicate a three-factor solution: Social Communication, Stereotyped Behaviors and Sensory Sensitivities, and Emotional Reactivity. The factors are meaningful, with the first two reflective of DSM-5 symptom domains. This study supports the continued relevance of the CARS in ASD assessment, and extends its utility in 2-year-old children.

Factor analysis of the feeding and eating in AutiSm Together Assessment / Karla K. AUSDERAU in Research in Autism Spectrum Disorders, 118 (October 2024)

The Feeding and Eating in AutiSm Together; FEAST, a caregiver-report questionnaire, was developed to characterize feeding challenges in autistic children ages 2 to 12 years. The purpose of this study is to determine the construct validity of the FEAST assessment using a large national sample of autistic children. Method A large national sample (N = 396) of caregivers completed the online survey. An ordinal confirmatory factor model using a robust weighted least squares approach validated the four predicted groupings of feeding challenges (sensory processing; behavior; oral.motor skills; and gastrointestinal) with generally strong loadings onto the four distinct.factors. Results Model fit statistics indicated good model fit (Robust Root Mean Square Error of.Approximation=.080, Robust Comparative Fit Index =.909, Robust Tucker-Lewis.Index=.901) Findings provide preliminary confirmation of the construct validity of the.FEAST assessment to characterize feeding difficulties for autistic children ages 2-12. Small to medium correlations between all factors indicate items successfully targeted.four unique areas of feeding challenge. For all factors, the largest correlation was with.behavior. Conclusion Assessments developed to address the complex feeding and mealtime challenges for.autistic children are essential to identify and integrate the most appropriate intervention.approaches. FEAST offers researchers and clinicians with a comprehensive and psychometrically sound assessment tool to address autistic children?s unique feeding.challenges.

Factor analysis of the Parenting Stress Index-Short Form with parents of young children with autism spectrum disorders / Anat ZAIDMAN-ZAIT in Autism Research, 4-5 (October 2011)

A secondary goal was to examine relationships between PSI-SF factors and autism severity, child behavior problems, and parental mental health variables that have been shown to be related to parental stress in previous research. A confirmatory factor analysis (CFA) was used to examine the three-factor structure described in the PSI-SF manual [Abidin, 1995]: parental distress, parent–child dysfunctional interaction, and difficult child. Results of the CFA indicated that the three-factor structure was unacceptable when applied to the study sample. Thus, an exploratory factor analysis was conducted and suggested a six-factor model as the best alternative for the PSI-SF index. Spearman's correlations revealed significant positive correlations with moderate to large effect sizes between the revised PSI-SF factors and autism severity, externalizing and internalizing child behaviors, and an index of parent mental health. The revised factors represent more narrowly defined aspects of the three original subscales of the PSI-SF and might prove to be advantageous in both research and clinical applications.

This is a self-report questionnaire for continuous and quantitative assessment of autistic spectrum traits in adults. Confirmatory factor analysis was performed on the five-factor model (social skill, attention switching, attention to detail, communication and imagination) proposed by the original authors, support not being found for this model in our sample. An exploratory factor analysis was then performed that resulted in an alternative three-factor model (social skills, details/patterns and imagination). Confirmatory factor analysis of the latter model revealed adequate psychometric indexes. The Brazilian version of the AQ was shown to be an adequate instrument for the evaluation of signs compatible with the autism spectrum in adults.

Examining Shared and Unique Aspects of Social Anxiety Disorder and Autism Spectrum Disorder Using Factor Analysis / Susan W. WHITE in Journal of Autism and Developmental Disorders, 42-5 (May 2012)

Given that the two conditions frequently co-occur, measurement of the characteristics unique to each condition is critical. This study evaluated the structure and construct overlap of two screening measures of SAD and ASD. Results from 623 young adults indicated that separable, though highly correlated, factors can be derived from the two measures related to social anxiety and social difficulties. The ASD screening measure also taps unique factors related to restricted interests and attention to details, theory of mind deficits, and a preference for routine. Recommendations are provided for accurate screening of symptoms of both SAD and ASD.
