Altered pre-ejection period response to social evaluative threat in adolescents with autism spectrum disorder / E. Kale EDMISTON in Research in Autism Spectrum Disorders, 36 (April 2017)
[article]
Titre : Altered pre-ejection period response to social evaluative threat in adolescents with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : E. Kale EDMISTON, Auteur ; Rachael A. MUSCATELLO, Auteur ; Blythe A. CORBETT, Auteur Article en page(s) : p.57-65 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Pre-ejection period Social evaluative threat Adolescence Social behavior Index. décimale : PER Périodiques Résumé : The autonomic nervous system (ANS) is involved in regulating social behavior; Autism Spectrum Disorder (ASD) is characterized by alterations in social behavior and reduced physiological response to threat. We hypothesized that adolescents with ASD would show reduced ANS response to social threat. Methods Eighteen males with ASD and thirteen males with typical development (TD), ages 12 to 17, completed a social threat paradigm while wearing an impedance cardiography apparatus. We calculated pre-ejection period (PEP) and tested for between-group differences in PEP response to social threat. We also conducted correlation analyses between PEP change scores and clinical symptom scales. Results There was an effect of diagnosis on change in PEP from baseline to the onset of social threat (F = 7.60, p = 0.01), with greater changes in PEP in TD compared to ASD. PEP change score and the Social Communication Questionnaire (r = 0.634, p = 0.005) and the ADHD Problems Subscale of the Child Behavior Checklist (r = 0.568, p = 0.014) were correlated. These findings suggest reduced arousal in response to social threat in ASD, with preliminary evidence that reduced sympathetic activation is associated with increased social behavior symptoms.

Participants wore a mobile electrocardiogram to collect heart rate data. There were significant group effects on respiratory sinus arrhythmia (RSA), a measure of parasympathetic nervous system function, with lower values in ASD (F = 4.97). Bivariate correlations also showed a significant relationship between parent reports of social problems and RSA response to the TSST (r = ?0.586). These findings suggest that autonomic dysregulation may contribute to social deficits in adolescents with ASD.

Titre : Salivary cortisol and behavioral response to social evaluative threat in adolescents with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : E. Kale EDMISTON, Auteur ; Scott D. BLAIN, Auteur ; Blythe A. CORBETT, Auteur Article en page(s) : p.346-358 Langues : Anglais (eng) Mots-clés : autism spectrum disorder adolescence cortisol HPA axis displacement behavior social evaluative threat Index. décimale : PER Périodiques Résumé : Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social behavior. One possible explanation for social communication deficits in ASD could be differences in biological systems that support responses to environmental stimuli. If so, it is unclear if differences in the arousal response to social stimuli in ASD are due to reduced interest in social information, or to an increased stress response. The hypothalamic pituitary adrenal axis facilitates arousal and the stress response to sensory input, including social stimuli. Previous research shows blunted cortisol response to social evaluative threat in children with ASD. The majority of prior work has focused on children with ASD, but adolescents with ASD are understudied. The adolescent period is of interest, as this developmental epoch is associated with increased salience of social evaluative threat in typically developing (TD) populations. In this study, we employed the Trier Social Stress Test (TSST), a laboratory paradigm that involves exposure to social evaluative threat, to study the cortisol and behavioral response to social evaluative threat in ASD and TD adolescents. Salivary cortisol data were collected at six time points before and after the TSST. Behavioral data were collected using video recordings of the TSST, which were then operationalized and coded. Paired sample t-tests were used to calculate within-group cortisol response to the TSST. Cortisol significantly increased in response to the TSST in the TD group but not the ASD group. The TD group showed a trend for more self-soothing behaviors during the stressor than the ASD group. The lack of a cortisol response to the TSST in the ASD group suggests that the TSST is not interpreted as stressful or salient for ASD adolescents.
