To test this hypothesis, fifty-three children with ASD (mean age = 11.9) underwent structural MRI and were divided into subgroups to compare those with at least one anxiety disorder diagnosis (n = 29) to those without (n = 24) and to a typically developing control group (TDC; n = 37). Groups were matched on age and intellectual level. The ASD and anxiety group showed decreased right amygdala volume (controlled for total brain volume) relative to ASD without anxiety (p = .04) and TDCs (p = .068). Results suggest that youth with ASD and co-occurring anxiety have a distinct neurodevelopmental trajectory.

Do Student Characteristics Affect Teachers' Decisions to Use 1:1 Instruction? / H. J. NUSKE 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.2864-2872 Titre : Do Student Characteristics Affect Teachers' Decisions to Use 1:1 Instruction?

MANDELL, Auteur Article en page(s) : p.2864-2872 Langues : Anglais (eng) Mots-clés : 1:1 Instruction  Child characteristics  Personalized medicine  Teacher decisions Index. décimale : PER Périodiques Résumé : One-to-one instruction is a critical component of evidence-based instruction for students with autism spectrum disorder, but is not used as often as recommended. Student characteristics may affect teachers' decisions to select a treatment and/or implement it. This study examined the associations between students' clinical and demographic characteristics and teachers' reported use of discrete trial training (DTT) and pivotal response training (PRT). Children's higher sensory symptoms, lower social approach, lower verbal skills and higher self-regulation difficulties were associated with more frequent 1:1 DTT and PRT. Results suggest that teachers give more frequent 1:1 instruction to children with more observable impairments, do not match children to type of 1:1 intervention, and may inadvertently neglect other students for whom individualized intervention may still be beneficial.

Profiles of Autonomic Activity in Autism Spectrum Disorder with and without Anxiety / V. PARMA in Journal of Autism and Developmental Disorders, 51-12 (December 2021)

Few studies have systematically assessed the resting physiological activity in ASD with co-occurring anxiety disorders. We tested 75 participants divided in four groups: youth with ASD, with (ASD?+?Anxiety?=?22, 6F, 12.29 ± 2.83 years old) and without co-occurring anxiety (ASD Alone?=?15, 6F, 11.59 ± 2.85 years old) and compared their physiological profile with that of matched typically developing controls (TDC) with (Anxiety Alone?=?16, 6F, 11.24 ± 3.36 years old) and without co-occurring anxiety disorders (TDC?=?22, 8F, 11.88 ± 2.88 years old). Results indicated reduced sympathetic and parasympathetic activity at rest in ASD as compared to TDC youth. ASD?+?Anxiety and Anxiety Alone groups showed different sympathetic, but similar parasympathetic activity. These findings suggest that autonomic profile-based approaches may advance research, diagnosis, and treatment of ASD and anxiety.
