Heart rate variability biofeedback as an anxiety intervention for college students with autism spectrum disorder / Kayla TRITES ; Brandon PARKER ; Nicholas BENSON in Research in Autism Spectrum Disorders, 110 (February 2024)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 110 (February 2024) . - p.102300 Titre : Heart rate variability biofeedback as an anxiety intervention for college students with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kayla TRITES, Auteur ; Brandon PARKER, Auteur ; Nicholas BENSON, Auteur Article en page(s) : p.102300 Mots-clés : Autism  Anxiety  Biofeedback  Higher education  Heart rate variability Index. décimale : PER Périodiques Résumé : Background Students with Autism Spectrum Disorder (ASD) attending higher education face an increased risk for the development of anxiety disorders. This can lead to poor academic outcomes, social difficulties, health problems, economic struggles, and other lifelong challenges. Heart Rate Variability Biofeedback Therapy (HRVBT) is a technique with preliminary positive results for the treatment of anxiety in individuals with ASD, although there is a need for more research. Method This pilot study explores the effect of using HRVBT to reduce anxiety for a cohort of autistic college students (N = 4) using a multiple baseline across participants design. Participants received 20-minute HRVBT sessions weekly over the span of a ten-week period. Heart rate variability (HRV) and self-reported ?state? (transitory) anxiety were measured to gauge both psychophysiological and perceived levels of anxiety. Results Measures of psychophysiological anxiety indicated improvements in HRV that are typically associated with improvement in anxiety level. Participants saw reductions in sub-optimal levels of HRV and improvements in optimal levels of HRV as the study progressed. However, participants did not report lower levels of state anxiety. Conclusions As expected, all participants in the study experienced statistically significant improvements in their HRV after receiving the intervention. Contrary to expectations, HRVBT increased variability in self-reports and did not produce an appreciable decrease in perceived state anxiety.

Heart Rate Variability in Children and Adolescents with Autism, ADHD and Co-occurring Autism and ADHD, During Passive and Active Experimental Conditions / Alessio BELLATO in Journal of Autism and Developmental Disorders, 52-11 (November 2022)

We investigated autonomic arousal in 106 children/adolescents with autism, ADHD, co-occurring autism/ADHD, and neurotypical controls. Heart rate variability was recorded during resting-state, a 'passive' auditory oddball task and an 'active' response conflict task. Autistic children showed hyper-arousal during the active task, while those with ADHD showed hypo-arousal during resting-state and the passive task. Irrespective of diagnosis, children characterised by hyper-arousal showed more severe autistic symptomatology, increased anxiety and reduced global functioning than those displaying hypo-arousal, suggesting the importance of considering individual autonomic arousal profiles for differential diagnosis of autism/ADHD and when developing personalised interventions.

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.

Heart rate variability moderates the effects of COVID-19-related stress and family adversity on emotional problems in adolescents: Testing models of differential susceptibility and diathesis stress / Jonas G. MILLER in Development and Psychopathology, 34-5 (December 2022)

Nevertheless, stress and adversity related to COVID-19 may be more consequential for some adolescents’ mental health than for others. We examined whether heart rate variability (HRV) indicated differential susceptibility to mental health difficulties associated with COVID-19 stress and COVID-19 family adversity. Approximately 4 years prior to the pandemic, we assessed resting HRV and HRV reactivity to a well-validated stress paradigm in 87 adolescents. During the pandemic, these adolescents (ages 13 “19) reported on their health-related stress and concerns about COVID-19, family adversity related to COVID-19, and their recent emotional problems. The association between COVID-19 stress and emotional problems was significantly stronger for adolescents who previously exhibited higher resting HRV or higher HRV reactivity. For adolescents who exhibited lower resting HRV or HRV augmentation, COVID-19 stress was not associated with emotional problems. Conversely, lower resting HRV indicated vulnerability to the effect of COVID-19 family adversity on emotional problems. Different patterns of parasympathetic functioning may reflect differential susceptibility to the effects of COVID-19 stress versus vulnerability to the effects of COVID-19 family adversity on mental health during the pandemic.

Heart rate variability responses to different affective inputs (affective touch and affective pictures) in autistic children and typically developing peers / José Antonio MINGORANCE ; Álvaro SABATER-GÁRRIZ ; Pedro MONTOYA in Research in Autism, 120 (February 2025)  

Public ISBD [article]  inResearch in Autism > 120 (February 2025) . - 202532 Titre : Heart rate variability responses to different affective inputs (affective touch and affective pictures) in autistic children and typically developing peers Type de document : Texte imprimé et/ou numérique Auteurs : José Antonio MINGORANCE, Auteur ; Álvaro SABATER-GÁRRIZ, Auteur ; Pedro MONTOYA, Auteur Article en page(s) : 202532 Langues : Anglais (eng) Mots-clés : Autism  Heart rate variability  Affective touch  Affective pictures  Behavior  Children Index. décimale : PER Périodiques Résumé : Purpose Heart rate variability (HRV) expresses autonomic responses to emotion perception. Although HRV has been examined during affective stimuli in autistic children, no evidence exists about differences in HRV produced by different stimulus modalities. This cross-sectional study aimed at comparing HRV during two modalities (affective touch and affective pictures) in autistic children and typically developing peers (TDP), and at exploring the factors influencing emotion-related HRV. Methods HRV time, frequency and non-linear indexes from 20 autistic children and 20 TDP were measured during resting state and different affective stimuli: affective/non-affective touch and pleasant/unpleasant/neutral pictures. Children rated stimulus valence and arousal and performed a task of emotion knowledge, and parents completed questionnaires on emotion regulation, behavior and sensory reactivity. Results Affective touch produced greater HRV responses in autistic children, whereas affective pictures modulated HRV in their TDP. Age, but not cognition, correlated with HRV in autistic children; scores of emotion knowledge, emotion regulation and behavior problems were associated with HRV indexes during affective stimulation in autistic children and TDP. Conclusion Different modalities of affective stimulation produce specific ANS regulation in autistic children. This must be considered for the design of experimental procedures and in the development and application of intervention protocols.
