Differences in anticipatory versus reactive stress to social evaluative threat in adults versus adolescents with autism / Julie LOUNDS TAYLOR in Autism Research, 11-9 (September 2018)  

Public ISBD [article]  inAutism Research > 11-9 (September 2018) . - p.1276-1285 Titre : Differences in anticipatory versus reactive stress to social evaluative threat in adults versus adolescents with autism Type de document : Texte imprimé et/ou numérique Auteurs : Julie LOUNDS TAYLOR, Auteur ; R. A. MUSCATELLO, Auteur ; B. A. CORBETT, Auteur Article en page(s) : p.1276-1285 Langues : Anglais (eng) Mots-clés : HPA axis  adolescence  adults  autism spectrum disorder  cortisol  stress Index. décimale : PER Périodiques Résumé : Social evaluative threat is a potent activator of the hypothalamic-pituitary-adrenocortical (HPA) axis in typically developing (TD) populations. Studies have shown that children and adolescents with autism spectrum disorder (ASD) show a blunted cortisol response to this type of stressor; yet, a previous study in adults with ASD reported a more prototypical stress response. The current study compared 24 adolescents and 17 adults with ASD to investigate a possible developmental lag in autism resulting in a more adaptive stress response to social evaluation with development. Participants were exposed to the trier social stress test (TSST), and salivary cortisol was collected before and after stress induction. Multilevel modeling revealed that relative to adolescents, young adults with ASD evidenced a significant increase in cortisol in response to anticipatory stress, and 23.5% were classified as anticipatory responders. Adolescents, however, had a significant change in slope in response to the TSST, with 37.5% classified as reactive responders. In both groups, the majority of participants did not have a robust stress response to the TSST as would be expected in TD participants. Findings suggest significant differences in the cortisol trajectory; adults with ASD were more likely to show an anticipatory response to being socially evaluated, which was maintained throughout the stressor, whereas the adolescents had a more reactive response pattern with no anticipatory response. Further research is needed to determine if such patterns are adaptive or deleterious, and to determine underlying factors that may contribute to distinct stress profiles and to the overall diminished stress responses. Autism Res 2018, 11: 1276-1285. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Many individuals have increased stress when being socially evaluated. The current study shows that adults with ASD have increased stress in anticipation of a task in which individuals are required to give a speech to unfamiliar raters, while adolescents with ASD tend to show a stress response only during the task itself. Further research is necessary to understand whether developmental influences on stress response in ASD have significant impacts on other areas of functioning often affected by stress.

Differences in Body Mass Index (BMI) in Early Adolescents with Autism Spectrum Disorder Compared to Youth with Typical Development / B. A. CORBETT in Journal of Autism and Developmental Disorders, 51-8 (August 2021)

The study included 241, 10-to-13-year-old youth with autism spectrum disorder (ASD, N?=?138) or typical development (TD, N?=?103). Standardized exams measured pubertal development, height (HT), weight (WT), heart rate (HR), blood pressure (BP) and Body Mass Index (BMI). Analysis of Variance showed no significant between-group differences for HT, WT, HR, or BP (all p?>?0.05). There was a significant difference in BMI-percentile between the groups (F(1,234)?=?6.05, p?=?0.01). Using hierarchical linear regression, significant predictors of BMI-percentile included diagnosis, pubertal stage and socioeconomic status. Pre-to-early pubescent children with ASD evidence higher BMI percentiles compared to youth with TD suggesting they may be at heightened risk for weight-related health concerns.

Pubertal Development Measurement in Children With and Without Autism Spectrum Disorder: A Comparison Between Physical Exam, Parent- and Self-Report / B. A. CORBETT in Journal of Autism and Developmental Disorders, 49-12 (December 2019)

The study compared physical examination to parent- and self-report measures in 200 participants (134 males and 66 females) ages 10.0-13.5 years. Both participants with typical development (TD, n = 78) and ASD (n = 122) were included. Concordance ranged from slight-to-fair for self-assessments (kappa = .17-.32) and slight-to-moderate for parent-report (kappa = .21-.44). Concordance of physical exam with self- and parent-report of the ASD group was somewhat lower than for the TD group. Findings indicate pubertal assessments by parent or child are not reliable indices of precise pubertal staging.

The impact of COVID-19 on stress, anxiety, and coping in youth with and without autism and their parents / B. A. CORBETT in Autism Research, 14-7 (July 2021)  

Public ISBD [article]  inAutism Research > 14-7 (July 2021) . - p.1496-1511 Titre : The impact of COVID-19 on stress, anxiety, and coping in youth with and without autism and their parents Type de document : Texte imprimé et/ou numérique Auteurs : B.

The study examined stress, anxiety, and coping in a data-driven, real-time assessment of 122 youth with and without ASD and their parents at the height of the COVID-19 shutdown and three-months later. Standardized measures were administered to ascertain stress and coping explicitly related to the pandemic (RSQ COVID-19-Child [self-report], Adult [self-report from the guardian of youth], Parent [report about child]) and anxiety (STAI-C, STAI-A). Multivariate, univariate analyses of variance and hierarchical regression were used. ASD youth endorsed more Trait anxiety and response to specific stressors (e.g., virus). Caregivers of youth with ASD (Adults) self-reported higher anxiety, yet scores were elevated for both groups. Adults of youth with ASD reported more stress, especially related to the virus, access to healthcare, and concern for the future. In the TD group, youth and adults used more Primary and Secondary Control Coping whereas ASD youth and adults used more Disengagement Coping. Adult stress was the primary predictor of parent perception of child stress as well as Child self-reported stress. While the ASD group was consistently high compared to the TD group, there were no significant changes over time for stress or anxiety. Results reveal striking differences in youth with ASD and their parents regarding stress, anxiety, and coping. Findings highlight the need for essential support, access to services, and strategies to enhance psychological and emotional well-being. LAY SUMMARY: This study examined stress, anxiety, and coping related to the COVID-19 pandemic in 61 youth with autism spectrum disorder (ASD) and 61 youth with typical development (TD) and their parents. Results showed that ASD youth reported more anxiety and stress. Adults of youth with ASD indicated higher self-reported anxiety and stress than adults of TD youth. TD youth and their parents reported using more adaptive coping strategies. Findings highlight the need for strategies to enhance psychological and emotional well-being.
