As a manipulation, parents were instructed to provide their children (N=79), aged 10-14 years, with standardized verbal threat or safety information about two strangers in the lab. Then, children engaged in a social interaction task with the two strangers (blind to their condition) separately, while child behavioral avoidance was recorded. Following the task, children reported fear beliefs for each stranger. Also, parents completed a self-report questionnaire on social anxiety symptoms. Children reported more fear beliefs for the stranger paired with the threat information, but no significant difference was found in observed avoidance. In addition, verbal threat information did not have a stronger influence on children’s observed avoidance in case of higher reported fear beliefs. Similarly, high parental social anxiety symptoms did not moderate the impact of verbal threat information on the child’s cognitive or behavioural fear indices. However, they did have a significant influence on behavioural avoidance, regardless of verbal information. Overall, this study shows a causal effect of verbal threat messages provided by parents only on child subjective fear and highlightsthe need for further research on the verbal transmission of childhood social fears in the context of family, by examining these processes in various social situations, age groups, and fear indices.Show less

Observing others’ emotions elicits physiological arousal in the observer, which is reflected in increased pupil diameter (i.e., pupil dilation). The current study used pupil dilation as an index of physiological arousal to explore children’s responses to emotional facial expressions. More specifically, we investigated whether maternal symptoms of depression and/or anxiety were related to offspring’s pupil responses to negative (versus positive) facial displays irrespective of the child’s symptomology. A community sample of 87 mother- (M = 42.30, SD = 5.60, range = 27-57) child (M = 10.11, SD = 1.32, range = 7.2-12.9) dyads participated in the current study. Mothers and offspring reported on their depressive and anxiety symptoms via self-report questionnaires. Children’s pupil responses to angry, fearful, sad, and happy dynamic facial displays were measured during the dynamic emotions task using eye-tracking. Results revealed that maternal depressive symptoms were not related to child pupil responses to negative (versus positive) faces. Higher levels of maternal anxiety, however, were linked to stronger child pupil responses to fearful and sad faces than to happy faces. In turn, child pupil responses to angry (versus happy) faces did not statistically differ as a function of maternal anxiety. These findings persisted after accounting for the link between child anxiety symptoms and child pupil responses. Therefore, the way typically developing children react to negative versus positive emotional faces in later childhood appears to be related to maternal levels of anxiety, but not to maternal levels of depression. This points to the importance of exploring maternal anxiety symptoms as a potential risk factor for the development of negativity biases in offspring across the general population.Show less

Previous studies investigating NAB and its links to depression were mainly conducted with clinical and at-risk adolescent and adult samples. Results of previous studies indicated depressed or at-risk individuals present NAB specifically towards depression-congruent stimuli (e.g., sad faces). This study is the first to investigate NAB and its links to depressive symptoms in non-clinical children. Moreover, the link between parental depressive symptoms and NAB in children was also investigated. In line with the previous studies, it was hypothesized children, like adults, will show NAB towards negative over positive emotional stimuli; children who have higher levels of depression will attend longer to sad faces in specific; children whose parents have higher levels of depression will attend longer to sad faces in specific. In a cross-sectional design, 90 8–12-year-old children and 84 parents (44 mothers) were tested. Children and parents’ dwell times to positive (happy) compared to negative (angry, fearful, sad) emotional expressions were measured using an eye-tracking task. Depressive symptoms were measured using the Children’s Depression Inventory (CDI) for children and the Beck’s Depression Inventory (BDI) for parents. While only one parent contributed to the eye-tracking task, both parents were asked to fill out the BDI. Results indicated although parents compared to children attended longer to all emotional expressions, both children and their parents attended longer to negative compared to positive emotions. No link between child depressive symptoms or parental depressive symptoms with NAB specific to sad faces was found in children. We conclude that children, like adults, show a negativity bias in their attention to emotional expressions; however, suggested links between child and parent depressive symptoms with NAB may not hold in non-clinical child samples. This study adds to the growing research on emotion-processing and vulnerability to depression in children.Show less

However, previous meta-analytic findings indicated that parenting accounted for only 5-11% of the variance in childhood depression, with varying effects for different types of parenting behaviors. Research Question: The current study aimed to investigate the association between observed negative/positive parenting behavior, childhood depression, and child gender, while controlling for the confounding effects of type of informant and assessment approach for childhood depression. Method: Two meta-analysis were conducted for the negative parenting – childhood depression and positive parenting – childhood depression association, while including moderating and confounding variables. The current study included thirty articles in total, with nineteen examining negative parenting behaviors and twenty-three examining positive parenting behaviors. Results: Observed negative parenting behavior was positively and observed positive parenting behavior was negatively related to childhood depression, with overall small effect sizes. Type of parenting behavior, child gender, and assessment approach for childhood depression did not moderate the associations. Type of informant for childhood depression explained some variance in the positive parenting – childhood depression association. Conclusions: Parenting interventions for childhood depression might aim to improve a broader range of parental behaviors. Future research is advised to compare actual to perceived parenting behaviors and investigate the direction of the parenting – childhood depression association, while adopting a multiple levels of analysis perspective. This could possibly contribute towards developing most effective personalized interventions for childhood depression, while lowering the high burden of depression.Show less
