Using qualitative methods to guide scale development for anxiety in youth with autism spectrum disorder / Karen E. BEARSS in Autism, 20-6 (August 2016)
[article]
Titre : Using qualitative methods to guide scale development for anxiety in youth with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Karen E. BEARSS, Auteur ; Christopher A TAYLOR, Auteur ; Michael G. AMAN, Auteur ; Robin WHITTEMORE, Auteur ; Luc LECAVALIER, Auteur ; Judith MILLER, Auteur ; Jill PRITCHETT, Auteur ; Bryson GREEN, Auteur ; Lawrence SCAHILL, Auteur Article en page(s) : p.663-672 Langues : Anglais (eng) Mots-clés : anxiety autism spectrum disorder content validity focus group instrument development qualitative methods Index. décimale : PER Périodiques Résumé : Anxiety is common in youth with autism spectrum disorder. Despite this common co-occurrence, studies targeting anxiety in this population are hindered by the under-developed state of measures in youth with autism spectrum disorder. Content validity (the extent to which an instrument measures the domain of interest) and an instrument’s relevance to the patient population are key components of measurement development. This article describes the application of qualitative research methods in the initial development of a parent-rated instrument of anxiety symptoms in youth with autism spectrum disorder. Overall, 48 parents of 45 children (aged 3–17?years) with autism spectrum disorder and at least mild anxiety participated in one of six focus groups at two sites (three groups per site). Systematic coding of the focus group transcripts identified broad themes reflecting the situations and events that trigger anxiety in children with autism spectrum disorder, the behavioral manifestations of anxiety in children with autism spectrum disorder, the parent and the child’s own response to anxiety, and broad behavioral patterns that could be associated with anxiety. From the focus group data, investigators generated 52 candidate items for a parent-rating of anxiety in youth with autism spectrum disorder. This report provides a detailed description of these early steps in developing a patient-oriented outcome measure.

Titre : Validation of DSM-IV Model of Psychiatric Syndromes in Children with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Luc LECAVALIER, Auteur ; Kenneth D. GADOW, Auteur ; Carla DEVINCENT, Auteur ; Michael C. EDWARDS, Auteur Année de publication : 2009 Article en page(s) : p.278-289 Langues : Anglais (eng) Mots-clés : Validity Autism Pervasive-developmental-disorder Psychiatric-disorder Nosology Factor-analysis Index. décimale : PER Périodiques Résumé : The objective of this study was to assess the internal construct validity of the DSM-IV as a conceptual model for characterizing behavioral syndromes in children with ASD. Parent and teachers completed the Child Symptom Inventory-4, a DSM-IV-referenced rating scale, for 6-to-12 year old clinic referrals with an ASD (N = 498). Ratings were submitted to confirmatory factor analysis and models were assessed for fit. Results were also compared to those obtained for a sample of non-ASD psychiatric outpatient school-age children. Fit indices ranged from acceptable to good for the ASD samples and compared well to those obtained in typically developing children. Findings lend support to the notion that DSM-IV syndromes may be an appropriate conceptual model for characterizing psychopathology in ASD.

KAAT, Auteur ; Luc LECAVALIER, Auteur ; Michael G. AMAN, Auteur Année de publication : 2014 Article en page(s) : p.1103-1116 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Aberrant Behavior Checklist Factor analysis Irritability Rating scales Assessment Index. décimale : PER Périodiques Résumé : The Aberrant Behavior Checklist (ABC) is a widely used measure in autism spectrum disorder (ASD) treatment studies. We conducted confirmatory and exploratory factor analyses of the ABC in 1,893 children evaluated as part of the Autism Treatment Network. The root mean square error of approximation was .086 for the standard item assignment, and in exploratory factor analysis, the large majority of items continued to load on the originally assigned factors. Correlations between the ABC subscales and multiple external variables including the Child Behavior Checklist and demographic variables supported the convergent and divergent validity of the ABC as a measure of behavior problems in ASD. Finally, we examined the impact of participant characteristics on subscale scores and present normative data.
