Bumping heart and sweaty palms: physiological hyperarousal as a risk factor for child social anxiety
How do parents' depression and anxiety, and infants' negative temperament relate to parent–infant face-to-face interactions?
The present study investigated the associations of mothers' and fathers' lifetime depression and anxiety symptoms, and of infants' negative temperament with parents' and infants' gaze, facial expressions of emotion, and synchrony. We observed infants' (age between 3.5 and 5.5 months, N = 101) and parents' gaze and facial expressions during 4-min naturalistic face-to-face interactions. Parents' lifetime symptoms of depression and anxiety were assessed with clinical interviews, and infants' negative temperament was measured with standardized observations. Parents with more depressive symptoms and their infants expressed less positive and more neutral affect. Parents' lifetime anxiety symptoms were not significantly related to parents' expressions of affect, while they were linked to longer durations of gaze to parent, and to more positive and negative affect in infants. Parents' lifetime depression or anxiety was not related to synchrony. Infants' temperament did not predict infants' or parents' interactive behavior. The study reveals that more depression symptoms in parents are linked to more neutral affect from parents and from infants during face-to-face interactions, while parents' anxiety symptoms are related to more attention to parent and less neutral affect from infants (but not from parents)
Parental Expressions of Anxiety and Child Temperament in Toddlerhood Jointly Predict Preschoolers’ Avoidance of Novelty
This study investigated the link between (a) parents’ social trait and state anxiety and (b) children’s fear and avoidance in social referencing situations in a longitudinal design and considered the modulating role of child temperament in these links. Children were confronted with a stranger and a robot, separately with their father and mother at 1 (N = 122), at 2.5 (N = 117), and at 4.5 (N = 111) years of age. Behavioral inhibition (BI) was separately observed at 1 and 2.5 years. Parents’ social anxiety disorder (SAD) severity was assessed via interviews prenatally and at 4.5 years. More expressed anxiety by parents at 4.5 years was not significantly linked to more fear or avoidance at 4.5 years. High BI children were more avoidant at 4.5 years if their parents expressed more anxiety at 2.5 years, and they were more fearful if the parents had more severe forms of lifetime SAD. More severe lifetime forms of SAD were also related to more pronounced increases in child fear and avoidance over time, whereas parents’ expressions of anxiety predicted more pronounced increases in avoidance only from 2.5 to 4.5 years. High BI toddlers of parents with higher state and trait anxiety become more avoidant of novelty as preschoolers, illustrating the importance of considering child temperamental dispositions in the links between child and parent anxiety. Moreover, children of parents with more trait and state anxiety showed more pronounced increases in fear and avoidance over time, highlighting the importance of early interventions targeting parents’ SAD. FSW - Self-regulation models for health behavior and psychopathology - ou
The interplay between expressed parental anxiety and infant behavioural inhibition predicts infant avoidance in a social referencing paradigm
Background: Anxiety aggregates in families. Environmental factors, such as modelling of anxious behaviours, are assumed to play a causal role in the development of child anxiety. We investigated the predictive value of paternal and maternal anxiety (lifetime anxiety disorders and expressed parental anxiety) on infants’ fear and avoidance during encounters with social and nonsocial novel stimuli in a social referencing (SR) paradigm.Methods: A total of 122 12-month-old infants participated in this study separately with their fathers and mothers (parents with lifetime: social anxiety disorders [n = 47], other types of anxiety disorders [n = 33], comorbid social and other types of anxiety disorders [n = 52] and without anxiety disorders [n = 112]). Infants were confronted with a stranger and a mechanical dinosaur as novel stimuli in two SR situations. Infants’ avoidance as well as fear and parents’ expressed anxiety were observed. Infants’ behavioural inhibition (BI) was separately observed in structured tasks. Results: Parental lifetime anxiety disorders did not significantly predict infant fear or avoidance. Expressed parental anxiety interacted with BI to significantly predict infant avoidance, revealing a positive association between expressed parental anxiety and infant avoidance among infants with moderate-to-high BI. The association between infant avoidance and expressed parental anxiety was not significantly different for mothers and fathers, pointing to an equally important role of fathers at this young age. Infant fear was significantly predicted by infant BI, but not by expressed parental anxiety. Conclusions: Infants with a temperamental disposition for anxiety (BI) may learn from both paternal and maternal anxious signals and become avoidant towards novelty when their parents express anxiety. This link between expressed parental anxiety and infant avoidance for moderate-to-high BI children, that seems to hold across contexts and to be independent of lifetime parental anxiety disorders, may be a mechanism explaining early intergenerational transmission of anxiety. FSW – Publicaties zonder aanstelling Universiteit Leide
"Covid-19 is dangerous": the role of parental verbal threat information on children's fear of Covid-19
Introduction Theoretical and empirical evidence suggests that the effect of parental verbal threat information on the offspring's fear acquisition of novel stimuli may be causal. The current study investigated this verbal fear acquisition pathway from parents to children in the unique context of Covid-19 as a novel environmental threat for parents and children. Methods Using an online cross-sectional survey, we collected data about fear of Covid-19, parent-child communication, parental anxiety, and child temperament, in the period between June 11th 2020 and May 28th 2021. Participants were 8 to 18-year-old children (N = 195; M-age = 14.23; 113 girls) and their parents (N = 193; M-age = 47.82; 146 mothers) living in the Netherlands. Results Children of parents with stronger Covid-19 fears also reported stronger Covid-19 fears. Moreover, parents who were more fearful of Covid-19 provided more threat-related information about the virus to their children. More parental threat information in turn was related to stronger fear of Covid-19 in their children, and partly mediated the link between parent and child fear of the virus. The link between parental threat information and children's fear of Covid-19 was not moderated by child temperament or parental anxiety. Conclusions Parental communication about Covid-19 may play a role in children's fear acquisition of Covid-19. The lack of moderation of this link by parental anxiety and child temperament may reflect the potentially adaptive nature of verbal fear transmission during the first year of the pandemic and the nonclinical levels of fear in this community sample.Stress-related psychiatric disorders across the life spa
Pre-verbal infants perceive emotional facial expressions categorically
Adults perceive emotional expressions categorically, with discrimination being faster and more accurate between expressions from different emotion categories (i.e. blends with two different predominant emotions) than between two stimuli from the same category (i.e. blends with the same predominant emotion). The current study sought to test whether facial expressions of happiness and fear are perceived categorically by pre-verbal infants, using a new stimulus set that was shown to yield categorical perception in adult observers (Experiments 1 and 2). These stimuli were then used with 7-month-old infants (N  =  34) using a habituation and visual preference paradigm (Experiment 3). Infants were first habituated to an expression of one emotion, then presented with the same expression paired with a novel expression either from the same emotion category or from a different emotion category. After habituation to fear, infants displayed a novelty preference for pairs of between-category expressions, but not within-category ones, showing categorical perception. However, infants showed no novelty preference when they were habituated to happiness. Our findings provide evidence for categorical perception of emotional expressions in pre-verbal infants, while the asymmetrical effect challenges the notion of a bias towards negative information in this age group
Machine Learning and Meta-Analysis Approach to Identify Patient Comorbidities and Symptoms that Increased Risk of Mortality in COVID-19
Background: Providing appropriate care for people suffering from COVID-19,
the disease caused by the pandemic SARS-CoV-2 virus is a significant global
challenge. Many individuals who become infected have pre-existing conditions
that may interact with COVID-19 to increase symptom severity and mortality
risk. COVID-19 patient comorbidities are likely to be informative about
individual risk of severe illness and mortality. Accurately determining how
comorbidities are associated with severe symptoms and mortality would thus
greatly assist in COVID-19 care planning and provision.
Methods: To assess the interaction of patient comorbidities with COVID-19
severity and mortality we performed a meta-analysis of the published global
literature, and machine learning predictive analysis using an aggregated
COVID-19 global dataset.
Results: Our meta-analysis identified chronic obstructive pulmonary disease
(COPD), cerebrovascular disease (CEVD), cardiovascular disease (CVD), type 2
diabetes, malignancy, and hypertension as most significantly associated with
COVID-19 severity in the current published literature. Machine learning
classification using novel aggregated cohort data similarly found COPD, CVD,
CKD, type 2 diabetes, malignancy and hypertension, as well as asthma, as the
most significant features for classifying those deceased versus those who
survived COVID-19. While age and gender were the most significant predictor of
mortality, in terms of symptom-comorbidity combinations, it was observed that
Pneumonia-Hypertension, Pneumonia-Diabetes and Acute Respiratory Distress
Syndrome (ARDS)-Hypertension showed the most significant effects on COVID-19
mortality.
Conclusions: These results highlight patient cohorts most at risk of COVID-19
related severe morbidity and mortality which have implications for
prioritization of hospital resources
