Parasympathetic withdrawal indexes risk for emotion dysregulation in children with autism spectrum disorder

Differential Relations Between Parenting and Emotion Regulation in Children with ASD Across Dyadic and Independent Contexts

Many children with ASD exhibit difficulties with emotion regulation that greatly impair functioning. Certain intrinsic correlates of dysregulation have been identified in this population, but the search for potential environmental influences has been less fruitful. The current study examined several aspects of parenting as correlates of observed regulation in Autistic children, as measured in both parent-child and independent regulatory contexts. A diverse sample of 76 children with ASD aged 6 to 10 years participated in frustrating laboratory tasks with and without their primary caregivers, and the caregivers completed a parenting questionnaire. Emotion regulation, parental scaffolding, and gentle guidance were coded from videotaped interaction, and scores of parental involvement, positive parenting, and inconsistent discipline were obtained through parent report. Differential relations were observed between parenting and children's regulation when considered across contexts, with parental scaffolding associated with children's dyadic regulation and parents' reports of their involvement and discipline associated with children's independent regulation. Findings support previous evidence identifying a potential delay in the internalization of parental co-regulatory support in Autistic children, and highlight parental involvement as a previously unidentified unique correlate of independent regulation in this population. Implications for conceptualizations of emotion regulation in autism are discussed as is the importance of extending findings through further longitudinal research.

Piloting a battery to evaluate parasympathetic reactivity and externalizing behaviours during early childhood in autism spectrum disorder

Background

Respiratory Sinus Arrhythmia Reactivity (RSA-R) correlates both positively and negatively with externalizing behavior in autistic individuals. These inconsistencies may result from task-based differences. This pilot study measured RSA-R in 4-to 6-year-olds, across two time-points, using four validated tasks with matched baseline and challenge periods. Social, cognitive, sensory, and emotional tasks were employed to evaluate the use of a domain-specific approach in measuring RSA-R in young autistic children.

Methods

RSA and parent-reported externalizing behavior were collected from 16 children (Mage=5.60 years; 13 male; 12 white/caucasian; 15 non-hispanic/latine). RSA-R was measured by the difference score of the challenge task minus its corresponding comparison task. Correlations were computed to evaluate associations between RSA-R and behavior.

Results

RSA was reliably measured for 3/4 tasks (.694 ≤ ICCs ≤ .896). Only RSA-R during a social task correlated with externalizing behavior. These results support using a battery that measures a range of challenges, differing in social demands, to characterize how arousal contributes to emotion regulation demands among young autistic children.

Examining the feasibility and utility of heart rate variability on intervention outcomes targeting emotion regulation in autism: a brief report

Autistic youth experience several behavioral and emotional characteristics that can predispose them to emotion dysregulation (ED). Current literature examining ED in autism spectrum disorder (ASD) is limited to parent- and self-reported measures, indicating a need for biological or physiological methods to better assess emotion regulation in ASD. Utilizing the autonomic nervous system, specifically heart rate variability (HRV), may be a promising method to objectively measure ED in ASD, given it is one of the body's primary means of regulating physiological arousal. Our pilot study is one of the first to examine the feasibility, utility, and construct validity of HRV along with clinical measures within an intervention targeting ED-specific symptoms in ASD. Participants included 30 autistic youth ages 8-17 years who participated in the pilot study of Regulating Together, a group-based intervention targeting emotion regulation. We demonstrate HRV is feasible, demonstrates adequate test-retest reliability, and is complimentary to clinician- and parent-reported measures. Our preliminary findings also point to certain HRV profiles being indicative of long-term outcomes after receiving treatment. HRV may be a useful, objective tool in determining differential needs of long-term follow-up care for treatment maintenance at screening or baseline stages.

Emotion regulation and emotion dysregulation in children and adolescents with Autism Spectrum Disorder: A meta-analysis of evaluation and intervention studies

Children and adolescents with Autism Spectrum Disorder (ASD) often experience challenges in emotion regulation (ER) and emotion dysregulation (ED) which can interfere with their adaptive functioning. This study aimed to systematically review and meta-analyze the evidence on ER/ED in children and/or adolescents with ASD, examining its relationship with the following variables: internalizing and externalizing symptoms, cognitive function and social skills, and the effectiveness of non-pharmacological interventions addressing ER difficulties. Both electronic and manual searches were conducted to identify potential studies. Fifty-five studies were included in the meta-analysis. A statistically significant between-group difference was found, suggesting greater ER/ED challenges in the ASD group. Also, the ASD group showed more maladaptive ER strategies and fewer adaptive ER strategies compared to the non-ASD participants. Additionally, more severe ASD and poorer social skills were associated with greater ED and poorer ER skills, respectivelly. Furthermore, there was a significant correlation between internalizing symptomatology and both adaptive and maladaptive ER strategies. Studies of non-pharmacological interventions showed significant improvement in both ER and ED. These results imply that assessing ER/ED in children and adolescents with ASD should be part of the evaluation process, and it should also be a focal point for intervention in this population.
