Symptom overlap on the srs-2 adult self-report between adults with asd and adults with high anxiety / Mikle SOUTH in Autism Research, 10-7 (July 2017)

Titre : Symptom overlap on the srs-2 adult self-report between adults with asd and adults with high anxiety Type de document : Texte imprimé et/ou numérique Auteurs : Mikle SOUTH, Auteur ; AnnaLisa W. CARR, Auteur ; Kevin G. STEPHENSON, Auteur ; Max E. MAISEL, Auteur ; Jonathan C. COX, Auteur Article en page(s) : p.1215-1220 Langues : Anglais (eng) Mots-clés : autism anxiety screening SRS-2 discriminant validity adults Index. décimale : PER Périodiques Résumé : Many people diagnosed with autism spectrum disorder (ASD) also experience significant symptoms of anxiety, while many people with anxiety disorders likewise experience social difficulties. These concerns can be difficult to tease apart in general clinical settings. The Social Responsiveness Scale (SRS) is one of the most frequently used measures of dimensional ASD symptoms. In order to investigate the overlap of autism and anxiety on the SRS, we compared three groups of adults (an ASD group, n?=?40; a high anxious group, n?=?56; and a typical comparison group, n?=?29) using the new Adult Self Report version of the SRS-2nd Edition (SRS-2-ASR) alongside a battery of anxiety questionnaires. Based on previous research with children from the parent-report SRS (first edition), we hypothesized that the SRS-2-ASR would have difficulty discriminating between the ASD and high anxious groups. Results showed that both these clinical groups scored significantly higher on the SRS than a typical control group. Discriminant validity was poor, including sensitivity of 0.65 when including all participants and 0.48 when only the two clinical groups were included. In particular, the Social Motivation subscale of the SRS-ASR failed to distinguish between ASD and anxiety groups. As recommended in the SRS-2 manual, we highlight the need for caution when using the SRS-2-ASR to support diagnostic decision making, especially in clinical settings involving anxiety, ADHD, or other concerns that can affect reciprocal social communication and/or behavioral flexibility.

Titre : The Interplay Between Sensory Processing Abnormalities, Intolerance of Uncertainty, Anxiety and Restricted and Repetitive Behaviours in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Sarah WIGHAM, Auteur ; Jacqui RODGERS, Auteur ; Mikle SOUTH, Auteur ; Helen MCCONACHIE, Auteur ; Mark FREESTON, Auteur Article en page(s) : p.943-952 Langues : Anglais (eng) Mots-clés : Sensory processing abnormalities Intolerance of uncertainty Anxiety Repetitive behaviours Autism spectrum disorder Index. décimale : PER Périodiques Résumé : Sensory processing abnormalities, anxiety and restricted and repetitive behaviours (RRBs) frequently co-occur in Autism Spectrum Disorders (ASD). Though the relationship between these phenomena is not well understood, emerging evidence indicates intolerance of uncertainty (IU) may play an important role. This study aimed to determine pathways between sensory abnormalities and RRBs, and the role anxiety and IU may have. We gathered caregiver report data for 53 children with ASD aged 8–16 years. We found sensory under responsiveness and sensory over responsiveness were significantly associated with repetitive motor and insistence on sameness behaviours, and the relationships significantly mediated by IU and anxiety. Our findings indicate different mechanisms may underpin repetitive motor and insistence on sameness RRBs, which can inform treatment interventions.

Titre : The measurement properties of the spence children's anxiety scale-parent version in a large international pooled sample of young people with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Iliana MAGIATI, Auteur ; Jian Wei LERH, Auteur ; Matthew J.

Despite an increasing number of studies, there is no clear agreement on which existing anxiety measure is more psychometrically sound and what is the factor structure of anxiety in ASD. The present study examined the internal consistency, convergent, divergent, and discriminant validity, as well as the factor structure of the Spence Children's Anxiety Scale-Parent Version (SCAS-P), in a large international pooled sample of 870 caregivers of youth with ASD from 12 studies in the United Kingdom, United States, and Singapore who completed the SCAS-P. Most were community recruited, while the majority had at least one measure of ASD symptomatology and either cognitive or adaptive functioning measures completed. Existing SCAS-P total scale and subscales had excellent internal consistency and good convergent, divergent and discriminant validity similar to or better than SCAS-P properties reported in typically developing children, except for the poorer internal consistency of the physical injury subscale. Confirmatory Factor Analysis (CFA) of the existing SCAS-P six-correlated factor structure was a poor fit for this pooled database. Principal component analysis using half of the pooled sample identified a 30-item five correlated factor structure, but a CFA of this PCA-derived structure in the second half of this pooled sample revealed a poor fit, although the PCA-derived SCAS-P scale and subscales had stronger validity and better internal consistency than the original SCAS-P. The study's limitations, the use of the SCAS-P to screen for DSM-derived anxiety problems in ASD and future research directions are discussed.

Titre : The perception and identification of facial emotions in individuals with autism spectrum disorders using the Let?s Face It!

MCPARTLAND, Auteur ; Martha D. KAISER, Auteur ; Robert T. SCHULTZ, Auteur Article en page(s) : p.1259-1267 Langues : Anglais (eng) Mots-clés : ASD computer-based assessment facial emotions perceptual skills social communication Index. décimale : PER Périodiques Résumé : Background: Although impaired social?emotional ability is a hallmark of autism spectrum disorder (ASD), the perceptual skills and mediating strategies contributing to the social deficits of autism are not well understood. A perceptual skill that is fundamental to effective social communication is the ability to accurately perceive and interpret facial emotions. To evaluate the expression processing of participants with ASD, we designed the Let?s Face It! Emotion Skills Battery (LFI! Battery), a computer-based assessment composed of three subscales measuring verbal and perceptual skills implicated in the recognition of facial emotions. Methods: We administered the LFI! Battery to groups of participants with ASD and typically developing control (TDC) participants that were matched for age and IQ. Results: On the Name Game labeling task, participants with ASD (N = 68) performed on par with TDC individuals (N = 66) in their ability to name the facial emotions of happy, sad, disgust and surprise and were only impaired in their ability to identify the angry expression. On the Matchmaker Expression task that measures the recognition of facial emotions across different facial identities, the ASD participants (N = 66) performed reliably worse than TDC participants (N = 67) on the emotions of happy, sad, disgust, frighten and angry. In the Parts?Wholes test of perceptual strategies of expression, the TDC participants (N = 67) displayed more holistic encoding for the eyes than the mouths in expressive faces whereas ASD participants (N = 66) exhibited the reverse pattern of holistic recognition for the mouth and analytic recognition of the eyes. Conclusion: In summary, findings from the LFI! Battery show that participants with ASD were able to label the basic facial emotions (with the exception of angry expression) on par with age- and IQ-matched TDC participants. However, participants with ASD were impaired in their ability to generalize facial emotions across different identities and showed a tendency to recognize the mouth feature holistically and the eyes as isolated parts.

Titre : The relationship between executive functioning, central coherence, and repetitive behaviors in the high-functioning autism spectrum Type de document : Texte imprimé et/ou numérique Auteurs : Mikle SOUTH, Auteur ; Sally OZONOFF, Auteur ; William M. MCMAHON, Auteur Année de publication : 2007 Article en page(s) : p.437-451 Langues : Anglais (eng) Mots-clés : Autism Central-coherence Executive-function Repetitive-behavior Index. décimale : PER Périodiques Résumé : This study examined the relationship between everyday repetitive behavior (primary symptoms of autism) and performance on neuropsychological tests of executive function and central coherence (secondary symptoms). It was hypothesized that the frequency and intensity of repetitive behavior would be positively correlated with laboratory measures of cognitive rigidity and weak central coherence. Participants included 19 individuals (ages 10—19) with high-functioning autism spectrum disorders (ASD group) and 18 age- and IQ-matched typically developing controls (TD group). There was partial support in the ASD group for the link between repetitive behavior and executive performance (the Wisconsin Card Sorting Task). There was no support for a link between repetitive behavior and measures of central coherence (a Gestalt Closure test and the Embedded Figures Test). Further research on repetitive behaviors in autism may benefit from a focus on narrow behavioral and cognitive constructs rather than general categories.
