Titre : Allied Health Professionals' Knowledge and Use of ASD Intervention Practices Type de document : Texte imprimé et/ou numérique Auteurs : J. PAYNTER, Auteur ; R. SULEK, Auteur ; S. LUSKIN-SAXBY, Auteur ; D. TREMBATH, Auteur ; D. KEEN, Auteur Article en page(s) : p.2335-2349 Langues : Anglais (eng) Mots-clés : Allied health professionals Autism spectrum disorder Evidence-based practice Implementation science Knowledge translation Index. décimale : PER Périodiques Résumé : Allied health professionals (AHPs) are trusted sources of information and intervention for clients with autism spectrum disorder. However, the level of implementation of empirically-supported therapies and the accuracy of the knowledge they use to inform intervention selection is largely unknown. The present study explored the accuracy of AHPs' knowledge and use of practices, and explored links to individual attitudes and organisational culture. Overall results from the 156 AHPs surveyed suggested general accuracy of knowledge, and use of empirically supported treatments, with accuracy linked to use. Use of practices unsupported by research was linked to organisational culture and openness to new interventions. The presence of misinformation and the impact on selection and use of effective practices are discussed.

SIMPSON, Auteur ; Jacquiline DEN HOUTING, Auteur ; J. ROBERTS, Auteur Article en page(s) : p.350-358 Langues : Anglais (eng) Mots-clés : anxiety autism spectrum disorder autistic children parent report Index. décimale : PER Périodiques Résumé : Anxiety symptomatology is frequently reported in autistic children, and the prevalence of anxiety disorder is estimated at around 40%. However, most studies have focused upon children of age 8 years or above, so little is known about early signs of anxiety in younger children with autism. This study sought to describe anxiety-related symptomatology in 95 5- to 6-year-old autistic children using the Anxiety Scale for Children with Autism Spectrum Disorder. Wide variability was found in levels of symptomatology with the most frequently reported items within the 'uncertainty' subscale and the least frequently reported items in the 'anxious arousal' subscale. Comparisons of those with scores less than or greater than 70 on adaptive behaviour suggests some influence of ability on presentation of anxiety-related symptomatology.

Titre : Exploring the Sensory Profiles of Children on the Autism Spectrum Using the Short Sensory Profile-2 (SSP-2) Type de document : Texte imprimé et/ou numérique Auteurs : K. SIMPSON, Auteur ; D. ADAMS, Auteur ; C. ALSTON-KNOX, Auteur ; Helen S. HEUSSLER, Auteur ; D. KEEN, Auteur Article en page(s) : p.2069-2079 Langues : Anglais (eng) Mots-clés : Autism Children Sensory Subtypes Index. décimale : PER Périodiques Résumé : The aim of this study was to identify sensory subtypes in children on the autism spectrum using the Short Sensory Profile-2 (SSP-2). Caregivers of children on the autism spectrum aged 4-11 years (n = 271) completed the SSP-2. Analysis using Dirichlet process mixture model identified a two-cluster model which provided the best solution to subtype sensory responses. Two distinct subtypes were identified: Uniformly elevated (67%) with high scores across all quadrants and Raised avoiding and sensitivity (33%) with raised scores in the avoiding and sensitivity quadrants. There were no differences between subtypes based on chronological age and autism characteristics measured using the social communication questionnaire (total score). Based on the SSP-2, children were reported to experience differences in responses to sensory input, in particular in the area of sensitivity and avoiding.

Titre : Parent descriptions of the presentation and management of anxiousness in children on the autism spectrum Type de document : Texte imprimé et/ou numérique Auteurs : D. ADAMS, Auteur ; K. YOUNG, Auteur ; K. SIMPSON, Auteur ; D. KEEN, Auteur Article en page(s) : p.980-992 Langues : Anglais (eng) Mots-clés : anxiety autism mental health parent report qualitative Index. décimale : PER Périodiques Résumé : The complex interaction between anxiety and autism has led to debate about the presentation of anxiety in individuals on the spectrum and questions about the extent to which traditional checklists assess the entire range of symptomatology. Moreover, studies to date have not explored how the presentation of anxiety may differ between settings. Through a combination of open-ended questions, closed questions and standardised measures, parents of 173 children (aged 6-13) on the autism spectrum provided (1) descriptors of their child's anxiety at home, school and in the community and (2) strategies used to reduce their child's anxiety in each setting. Over half (52.6%) felt their child was anxious at home, 77.6% at school and 76.2% in the community. Parents reported differing presentations of anxiety between settings, with the majority of descriptions relating to observable, behavioural changes (e.g. hides/shuts down, repetitive behaviours) rather than cognitive or physiological signs. Parents also reported using different strategies across settings. The use of open-ended questions allowed the identification of signs of anxiety not explored within traditional questionnaires and highlighted the potential for signs to vary across settings. This knowledge is critical to inform the development or adaptations of anxiety measures and interventions.

Addressing these needs requires a detailed understanding of their communication trajectories. In this study, we used the language environment and analysis (LENA) system to examine possible changes in children's (a) vocalizations and (b) ratio of speech to nonspeech vocalizations over a 10-month period. Data for 23 children with ASD (17M, 6F; ages 32-67 months) were analyzed, including monthly 3-hr in-class recordings and standardized measures of language, cognition, and ASD characteristics. Using hierarchical generalized linear models, we found significant time-trends for child vocalizations (P = 0.001) and the vocalization ratio (P = 0.02), reflecting a waxing and waning pattern. Children with higher expressive language scores (Mullen scales of early learning, Vineland adaptive behavior scales - 2nd Ed.) and nonverbal cognition (Mullen scales of early learning), and fewer ASD characteristics (social communication questionnaire) demonstrated greater increases in the vocalization ratio over time (P values 0.04-0.01). Children with greater language and cognition difficulties were the most vocal, but produced a higher proportion of nonspeech vocalizations. The results demonstrate that significant fluctuations, as opposed to linear increases, may be observed in children with ASD receiving intervention, highlighting the value of assessment at multiple time-points. In addition, the findings highlight the need to consider both the quantity (vocalization counts) and quality (ratio of speech to nonspeech vocalizations) when interpreting LENA data, with the latter appearing to provide a more robust measure of communication. Autism Research 2019, 12: 830-842. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY ABSTRACT: In this study, we examined possible changes in speech and nonspeech vocalizations in 23 children with autism attending a comprehensive early intervention program over a 10-month period. Contrary to our expectation, we observed a waxing and waning pattern of change in children's vocalizations over time, rather than a steady increase. We also found evidence to suggest that looking at the quality of children's vocalizations (i.e., the ratio of speech to nonspeech vocalizations) provides a more accurate picture of children's development than simply looking at the quantity (i.e., how frequently they vocalize).
