Titre : The role of emotion regulation and core autism symptoms in the experience of anxiety in autism Type de document : Texte imprimé et/ou numérique Auteurs : Caitlin M. CONNER, Auteur ; Susan W. WHITE, Auteur ; Lawrence SCAHILL, Auteur ; Carla A. MAZEFSKY, Auteur Article en page(s) : p.931-940 Langues : Anglais (eng) Mots-clés : anxiety core autism spectrum disorder symptoms emotion regulation reactivity Index. décimale : PER Périodiques Résumé : Many children with autism spectrum disorder have problems with managing their emotions (emotion regulation) and anxiety. In this study, over 1000 parents completed an online survey which showed that emotion regulation and anxiety are closely linked. Although emotion regulation and anxiety are inter-connected, the results also show that autism symptoms play an important role in anxiety in autism spectrum disorder. Emotion regulation problems may be an important target for the treatment of anxiety in autism.

Titre : Trial Design Challenges When Combining Medication and Parent Training in Children with Pervasive Developmental Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Lawrence SCAHILL, Auteur ; Kimberly A.

Eugene ARNOLD, Auteur ; Ann WAGNER, Auteur ; James T. MCCRACKEN, Auteur Année de publication : 2009 Article en page(s) : p.720-729 Langues : Anglais (eng) Mots-clés : Autism Clinical-trial-methodology Risperidone Behavior-therapy Index. décimale : PER Périodiques Résumé : This paper presents the rationale for a 24-week, randomized trial designed to test whether risperidone plus structured parent training would be superior to risperidone only on measures of noncompliance, irritability and adaptive functioning. In this model, medication reduces tantrums, aggression and self-injury; parent training promotes improvement in noncompliance and adaptive functioning. Thus, medication and parent training target related, but separate, outcomes. At week 24, the medication was gradually withdrawn to determine whether subjects in the combined treatment group could be managed on a lower dose or off medication without relapse. Both symptom reduction and functional improvement are important clinical treatment targets. Thus, experimental evidence on the beneficial effects of combining pharmacotherapy and exportable behavioral interventions is needed to guide clinical practice.

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 : Using the big data approach to clarify the structure of restricted and repetitive behaviors across the most commonly used autism spectrum disorder measures Type de document : Texte imprimé et/ou numérique Auteurs : M. ULJAREVIC, Auteur ; B. JO, Auteur ; T. W. FRAZIER, Auteur ; Lawrence SCAHILL, Auteur ; Eric A. YOUNGSTROM, Auteur ; A. Y. HARDAN, Auteur Article en page(s) : 39 p. Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Circumscribed interest Factor analysis Insistence of sameness Repetitive motor behavior Index. décimale : PER Périodiques Résumé : BACKGROUND: Restricted and repetitive behaviors (RRB) in autism spectrum disorder (ASD) encompass several distinct domains. However, commonly used general ASD measures provide broad RRB scores rather than assessing separate RRB domains. The main objective of the current investigation was to conduct a psychometric evaluation of the ability of the Social Responsiveness Scale (SRS-2), the Social Communication Questionnaire (SCQ), the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) to capture different RRB constructs. METHODS: Exploratory Structural Equation Modeling (ESEM) was conducted using individual item-level data from the SRS-2, SCQ, ADI-R and the ADOS. Data were obtained from five existing publicly available databases. For the SRS-2, the final sample consisted of N?=?16,761 individuals (M(age)?=?9.43, SD?=?3.73; 18.5% female); for the SCQ, of N?=?15,840 (M(age)?=?7.99, SD?=?4.06; 18.1% female); for the ADI-R, of N?=?8985 (M(age)?=?8.86, SD?=?4.68; 19.4% female); and for the ADOS, of N?=?6314 (M(age)?=?12.29, SD?=?6.79; 17.7% female). RESULTS: The three-factor structure provided the most optimal and interpretable fit to data for all measures (comparative fit index???.983, Tucker Lewis index???.966, root mean square error of approximation???.028). Repetitive-motor behaviors, insistence on sameness and unusual or circumscribed interests factors emerged across all instruments. No acceptable fit was identified for the ADOS. LIMITATIONS: The five datasets used here afforded a large as well as wide distribution of the RRB item scores. However, measures used for establishing convergent and divergent validity were only available for a portion of the sample. CONCLUSIONS: Reported findings offer promise for capturing important RRB domains using general ASD measures and highlight the need for measurement development.
