BOGELS, Auteur Article en page(s) : p.1047-1055 Langues : Anglais (eng) Mots-clés : Social anxiety disorder  autonomic arousal  blushing  intergenerational transmission  high-risk design Index. décimale : PER Périodiques Résumé : Objective Autonomic hyperarousal in social situations is considered a genetic vulnerability factor for social anxiety disorder (SAD), but so far it is unstudied in children at risk for developing SAD. We examined autonomic activity during socially stressful tasks in children of mothers and fathers with and without lifetime SAD to reveal possible biological mechanisms of intergenerational transmission of SAD. Methods One hundred ten children aged 4.5 years were asked to sing a song in front of an audience and watch back their performance in the presence of that audience. Heart rate (HR), heart rate variability (HRV), electrodermal activity (EDA), and blushing (cheek blood flow and temperature) were measured in anticipation of, during, and after the tasks. Both parents’ lifetime SAD status was assessed, and both parents reported about their own and their child's social anxiety symptoms. Results Children of parents with lifetime SAD blushed more during the socially challenging tasks than children of parents without SAD. Moreover, children of parents with more social anxiety symptoms showed increased EDA throughout the tasks. Finally, more blushing, increased EDA, and reduced HRV were associated with greater child social anxiety. Conclusions This study adds to the current knowledge on the intergenerational transmission of SAD by providing evidence that children at risk for SAD are characterized by excessive blushing in socially challenging situations. The findings also demonstrate that heightened autonomic activity is a characteristic of social anxiety already during early childhood. Hence, autonomic hyperarousal, and blushing in particular, is likely to play an etiological role in the development of SAD.

Bumping heart and sweaty palms: physiological hyperarousal as a risk factor for child social anxiety / Milica NIKOLIC in Journal of Child Psychology and Psychiatry, 59-2 (February 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-2 (February 2018) . - p.119-128 Titre : Bumping heart and sweaty palms: physiological hyperarousal as a risk factor for child social anxiety Type de document : Texte imprimé et/ou numérique Auteurs : Milica NIKOLIC, Auteur ; Evin AKTAR, Auteur ; Susan M. BOGELS, Auteur ; Cristina COLONNESI, Auteur ; Wieke VENTE, Auteur Article en page(s) : p.119-128 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Physiological hyperarousal in social situations is a characteristic of individuals with social anxiety disorder (SAD), but so far it has been rarely studied as a biological risk for SAD. Here, we investigate whether children at high risk for SAD (because of their parents’ SAD) display physiological hyperarousal while interacting with a stranger. Also, we examine whether early physiological hyperarousal is related to later child social anxiety. Method One hundred and seventeen children took part in the stranger?approach task when they were 2.5 and 4.5 years old. Heart rate (HR), heart rate variability (HRV), and electrodermal activity (EDA) were measured before, during, and after the conversation with a stranger. Both parents’ lifetime SAD status and SAD severity were assessed before the birth of the child. Both parents and children reported on children's social anxiety symptoms when children were 7.5. Results Children of parents with the lifetime SAD diagnosis did not differ in their physiological activity from children of parents without lifetime SAD. However, children of parents with more severe SAD displayed heightened EDA throughout the task procedure. Increased HR and reduced HRV during the stranger?approach and elevated EDA throughout the task phases were linked to later child social anxiety. Conclusions Parents’ severity of SAD is related to child physiological hyperarousal early in their childhood. In addition, physiological hyperarousal in early childhood predicts later child social anxiety. Together, these findings suggest that early physiological hyperarousal in social situations may pose a risk for later child social anxiety and that physiological hyperarousal, and EDA in particular, may be a biological mechanism in the intergenerational transmission of SAD.

The unique contribution of blushing to the development of social anxiety disorder symptoms: results from a longitudinal study / Milica NIKOLIC in Journal of Child Psychology and Psychiatry, 61-12 (December 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-12 (December 2020) . - p.1339-1348 Titre : The unique contribution of blushing to the development of social anxiety disorder symptoms: results from a longitudinal study Type de document : Texte imprimé et/ou numérique Auteurs : Milica NIKOLIC, Auteur ; Mirjana MAJDANDŽI?, Auteur ; Cristina COLONNESI, Auteur ; Wieke DE VENTE, Auteur ; Eline MÖLLER, Auteur ; Susan M. BOGELS, Auteur Article en page(s) : p.1339-1348 Langues : Anglais (eng) Mots-clés : Social anxiety disorder  behavioral inhibition  blushing  self-consciousness Index. décimale : PER Périodiques Résumé : BACKGROUND: Self-conscious emotional reactivity and its physiological marker - blushing has been proposed to be an etiological mechanism of social anxiety disorder (SAD), but so far, untested in longitudinal designs. This study tested, for the first time, whether self-conscious emotional reactivity (indexed as physiological blushing) contributes to the development of SAD symptoms over and above social behavioral inhibition (BI), which has been identified as the strongest predictor of SAD development in early childhood. METHODS: One hundred fifteen children (45% boys) and their mothers and fathers participated at ages 2.5, 4.5, and 7.5 years. Social BI was observed at all time points in a stranger approach task, and physiological blushing (blood volume, blood pulse amplitude, and temperature increases) was measured during a public performance (singing) and watching back the performance at ages 4.5 and 7.5. Child early social anxiety was reported by both parents at 4.5 years, and SAD symptoms were diagnosed by clinicians and reported by both parents at 7.5 years. RESULTS: Higher social BI at 2.5 and 4.5 years predicted greater social anxiety at 4.5 years, which, in turn, predicted SAD symptoms at 7.5 years. Blushing (temperature increase) at 4.5 years predicted SAD symptoms at 7.5 years over and above the influence of social BI and early social anxiety. CONCLUSIONS: That blushing uniquely contributes to the development of SAD symptoms over and above social BI suggests two pathways to childhood SAD: one that entails early high social BI and an early onset of social anxiety symptoms, and the other that consists of heightened self-conscious emotional reactivity (i.e. blushing) in early childhood.
