Children who are on the autism spectrum also commonly demonstrate challenging behaviors, and their caregivers report increased levels of strain in daily life. The aim of this study was to explore four sensory processing features; seeking, avoiding, sensitivity, and registration, and their relationships with maladaptive behaviors in children with autism, as well as with caregiver strain. Participants comprised 75 children with autism aged 7-12?years (M?= 7.81). Caregivers completed three questionnaire measures examining child sensory processing, maladaptive behaviors, and perceptions of caregiver strain. We found avoiding significantly associated with irritability. Avoiding also displayed the strongest relationship with global caregiver strain. Avoiding and seeking were strongly related to hyperactivity/noncompliance (components of maladaptive behavior). A multiple regression was performed to explore how atypical sensory processing features and maladaptive behaviors together predicted caregiver strain. Together, maladaptive behaviors and sensory features accounted for 58% of the variance in total caregiver strain. The only significant individual predictor of total caregiver strain was sensory avoiding, which uniquely accounted for 5.76% of the variation. The findings suggest that atypical sensory processing is associated with overall caregiver strain, above that explained by maladaptive behaviors. Implications for targeted support for the benefit of the child, parents and family unit are discussed. LAY SUMMARY: Children who are on the autism spectrum often have differences in sensory processing. These children also tend to show challenging behaviors, and their caregivers can experience increased stress. This study looked at how sensory processing difficulties relate to such behaviors and caregiver stress. We found that both sensory processing and challenging behaviors were related to the amount of stress caregivers felt. This suggests that interventions may benefit from looking at sensory processing features when considering how to help reduce challenging behaviors and caregiver stress.

Heart Rate Variability in Children With Autism Spectrum Disorder and Associations With Medication and Symptom Severity / Rinku THAPA in Autism Research, 14-1 (January 2021)  

Public ISBD [article]  inAutism Research > 14-1 (January 2021) . - p.75-95 Titre : Heart Rate Variability in Children With Autism Spectrum Disorder and Associations With Medication and Symptom Severity Type de document : Texte imprimé et/ou numérique Auteurs : Rinku THAPA, Auteur ; Izabella POKORSKI, Auteur ; Zahava AMBARCHI, Auteur ; Emma THOMAS, Auteur ; Marilena M. DEMAYO, Auteur ; Kelsie A. BOULTON, Auteur ; Slade MATTHEWS, Auteur ; Shrujna PATEL, Auteur ; Indra SEDELI, Auteur ; Ian B. HICKIE, Auteur ; Adam J. GUASTELLA, Auteur Article en page(s) : p.75-95 Langues : Anglais (eng) Mots-clés : autonomic nervous system  heart rate variability  parasympathetic nervous system  psychotropic medication  social development  sympathetic nervous system  symptom severity Index. décimale : PER Périodiques Résumé : Decreased heart rate variability (HRV) is considered a common marker of autonomic dysfunction that contributes to poor health outcomes. While some studies have suggested that children with autism spectrum disorder (ASD) show reduced HRV, research is yet to consider whether this may be associated with medication use and symptom severity. This study examined the relationship between resting state HRV, medication use and symptom severity in children diagnosed with ASD. Children with ASD (N = 86), aged between 3 and 12?years (M = 8.09), were compared to 44 neurotypical children of similar age (M = 7.15). Laboratory assessment of HRV involved 5?min of non-invasive baseline electrocardiogram assessments while participants viewed an age-appropriate non-verbal animated video. Time-domain and frequency-domain HRV measures were analyzed. ASD symptom severity was assessed using the Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) and Social Responsiveness Scale (SRS-2). Results indicated that children with ASD exhibited reduced resting HRV relative to neurotypical children. Subsequent analyses within the ASD group suggested that this group difference was greater in children who were taking psychotropic medication (N = 36). Our data also provides tentative evidence of a relationship between HRV and social impairment symptoms in children with ASD, with more severe repetitive behaviors (as measured by the ADOS-2) associated with decreased resting HRV. Overall, these findings suggest that HRV may be atypical in children with ASD and suggest the importance of exploring HRV as a risk factor for cardiovascular health in this group. LAY SUMMARY: Cardiac activity, such as heart rate variability (HRV), can provide insight into the autonomic nervous system. This study reports on the association between resting-state HRV and autonomic nervous system activity in young children with autism spectrum disorder (ASD) compared to neurotypical children. These results may help us understand what underlies autonomic nervous system dysfunction and the potential pathophysiological mechanisms leading to increased cardiovascular risk in ASD.
