This may hamper therapist-patient communication when discussing the score and the interpretation of where a patient can be placed on a severity scale. Expressing scores on a standardized common metric can facilitate the communication between therapist and patient. This thesis aims for a method that enables an easier interpretation of scores and in addition produces scores with a normal distribution. Method: Using the data of four anxiety questionnaires, namely the Brief Scale for Anxiety (BSA), the PADUA Inventory Revised (PI-R), the Panic Appraisal Inventory (POL/PAI) and the Impact of Events Scale Revised (IES-R), theta-based T-scores were calculated with the Item-Response Theory and deployed as a basis for crosswalk tables to look up T-scores from raw scores. Based on these crosswalk tables, transformation formulas were established to calculate T-scores. To validate these, calculated T-scores were compared to theta-based T-scores. Results: Most of the calculated T-scores had a normal distribution and the correlations between both methods to arrive at the T-scores were significant, the highest correlation was found for the BSA and the IES-R. Discussion: Due to a significant correlation and a large sample size a new method to arrive at a common metric was established by linking every raw score on a T-score metric. This provides a way to facilitate the interpretation and discussion of outcome scores. Further, with this new method disorder severity can be calculated and looked up due to tangible cut-off scores.Show less

It was expected that children would have more fear beliefs and attention towards the stranger paired with parental verbal threat comments compared to the stranger paired safe comments and that BI would have a moderating role on the effect of parental verbal comments. The sample consisted of 4-6-year-olds. In the experiment a manipulation was used where one stranger was paired with threat comments and the other one with safe comments, both given by the parent. Then, the children encountered the strangers during a social and interaction task. The results show that children’s fear beliefs about the stranger paired with parental threat comments were significantly higher than about the stranger paired with parental safe comments. This was not the case for children’s attention towards the strangers. So, parental verbal threat comments paired with a stranger led to more fear beliefs but did not increase attention. Furthermore, the moderating role of temperament was not significant. To conclude, this study supports the growing evidence that children's fear beliefs can be changed by giving information but did not found this effect for attention. Also, the effect of verbal threat information on fear beliefs and attention did not differ as a function of child temperament.Show less

One origin of fear is verbal transmission, i.e. the receiving of threatening information. In frightening situations, one’s heart rate (HR) increases. However, in some studies no heightened HR was found in people with SAD. This might mean that the link between stressor and HR is moderated. Behavioural inhibition (BI) was found to be such a moderator. In our study, we examine the following two research questions: What is the effect of exposure to verbal expressions of anxiety (versus safety) from parents on their children’s physiological reactions to strangers? Are the physiological responses more pronounced with temperamentally fearful children? Methods. Together with their main caregiver, 51 children between 4-6 years of age came to the lab after both of their parents had filled in the Behaviorual Inhibition Questionnaire (BIQ) for them. Children had a conversation with two strangers, one at a time. Before the conversation, parents told the children that one of the strangers was friendly, while the other one was mean. Throughout the experiment the children’s HR was measured. Results. Children’s HR neither was significantly higher during the threat condition, nor did BI cause a significantly increased HR. Conclusion and implications. The results do not suggest a significant effect of verbal transmission on HR. Also the child’s temperament did not significantly alter that effect. More research on young children needs to be done to develop early interventions for children at risk of SAD.Show less

One way in which anxiety is transmitted from parents to children is through parental verbal information, which induces attentional biases towards threat-associated animals over safety-associated animals. However, this effect has only been researched with unknown animals as the subject of information. Therefore the current study aimed to investigate the effect of parental verbal information on children’s attentional bias in a social situation, using human strangers as the subject of information. Additionally, the moderating role of child social anxiety was explored. For this study, children (aged 4-6, N=52) visited the lab with their primary caregiver. The caregivers then transferred messages to their children about two strangers: one paired with positive information, one with negative information. After the children completed a social performance task with the strangers posing as judges, the children completed a visual search task with pictures of the strangers to measure children’s attentional bias towards the strangers. Also, child social anxiety was measured by parental report on a questionnaire. A repeated measures ANOVA showed no significant effect of parental verbal information on child attentional bias. Child social anxiety also did not affect this relationship. The absence of a significant effect of verbal information on attentional bias can be explained by the non-aversive experience children had with the strangers. If this possible extinction effect is found in future studies as well, it may have implications for the extended use of exposure therapy in the treatment of child social anxiety.Show less

In the cross-sectional study, Polish mothers and their 4 months old infants (N-163) were tested in two different meetings. The mothers filled out EPDS, RLCQ, IBQ-R and a survey concerning their breastfeeding pattern. Furthermore, breast milk samples were collected to assess oxytocin, cortisol and energy levels in milk. The findings does not support the prediction that maternal stress influences infants’ temperamental traits. The results of the study indicated that oxytocin in mother’s milk was significantly associated with negative affectivity. However, no significant association was found between temperamental traits and cortisol. Moreover, nursing frequency was also significantly related to higher negative affectivity, however, the relationship is in the opposite direction of what is expected.Show less

This experimental study investigated the influence of threat and safety messages regarding strangers in the parent-to-child transmission of fear and considered the moderating role of children’s temperamental anxiety dispositions of behavioral inhibition (BI). The children included in this study were 4 to 6 years old (n = 68). Parents were asked to deliver manipulated verbal information (threat versus safety) to their children in reference to strangers whom later evaluate their children’s social performance. Children’s fear beliefs were measured prior to the social performance task. BI scores were assessed via online questionnaires and the children’s fear belief scores were assessed by administering a Fear Beliefs Questionnaire (FBQ). The children significantly reported more fear beliefs regarding the strangers assigned to the threat condition compared to the strangers assigned to the safety condition. This effect was not moderated by child BI. No significant overall association was found between the parents’ reports of BI and the children’s fear beliefs. Our study contributes to the emerging literature on the parental verbal pathway as an important mechanism through which children acquire fear by addressing stranger anxiety as another form of fear that can be verbally acquired. Future research should investigate samples of children with high BI levels to see whether this group is more influenced by their parents’ comments than a typically developing sample.Show less

The most prevalent way to transmit anxiety from parent to child in daily life is through verbal communication of threat information. The way that verbal transmission of information affects the behavior of children, and the possible moderating effect of parental anxiety, has not received much attention in scientific papers. Using an experimental manipulation, this study investigated how parental threat and safety information about strangers affected the observed behavior (avoidance and anxiety) of children towards these strangers. Children (aged four to six) were exposed to threat and safety information by their fathers or mothers regarding two judges. Children then completed two social tasks with the judges, one performance and one interaction, during which their behavior was observed. Parental anxiety was measured using the SCARED-A questionnaire. Results showed no significant effect of verbal safety and threat information on the observed anxious and avoidant behavior of children. Results also showed that parents’ general anxiety levels did not moderate the effect of the verbal comments. Thus, can be concluded that verbal threat and safety information seems to have no effect on behavior in children towards strangers, nor can behavior be predicted from parental anxiety.Show less

In order to provide proper prevention more research is needed on the factors leading to social anxiety in children. Apart from the genetic’s component, environmental factors can contribute to the parent to child transmission of SAD (Wong & Rapee, 2016). One environmental factor is the verbal information provided by parents to their children. Lang and Levis (1970) proposed that verbal information acts on physiological factors such as heart rate (HR). Yet, little is known about how verbal information affects heart rate in children in a social situation. The current study investigated the effect of verbal information provided by parents on the heart rate of children in a social situation while taking into account the effect of behavioral inhibition as a moderator. The sample consisted of 51 typically developed children aged 4-6 years. In the current study parents provided their children with safety and threat information about strangers. Heart rate of the children was measured during an interaction task with the strangers linked to the threat and safe information. The results did show that the nature of the verbal information paired with the strangers did not differently influence child HR responses to these strangers during the social interaction tasks. Moreover, there was neither a moderation effect nor a main effect of the covariate behavioral inhibition. This shows that in the social situation the verbal information given by their parents was not strong enough to trigger a different hear rate response in childrenShow less

Additionally, this study considered the moderating role of social anxiety levels of the parent who provided the information to the child on the effect of verbal threat information. The sample consisted of 68 American children ranging from age 4 to 6. These children were told they had to perform for, and interact with two different judges (strangers). The children were provided with threat or safety information about the judges by their parent. Fear beliefs regarding each judge were assessed after the manipulation using an adapted version of the Fear Beliefs Questionnaire. Results indicated that verbal threat information from parents resulted in significantly higher fear beliefs in children about these judges than when safety information was provided. Parental general social anxiety did not moderate this effect. This is the first study to show that parental verbal threat information is effective in triggering higher fear beliefs about strangers in 4 to 6-yearold children than safety information. Thereby this study provides insight into the parent to child transmission of social anxiety via verbal threat information.Show less

Evidence of the parental verbal transmission on social fear beliefs and the moderating role of BI is missing. We examined the effect of threat versus safety parental verbal transmission on child fear beliefs of strangers, and the moderating role of BI in this pathway. The typical development sample consisted of children (N = 68) between 4-6 year with a caregiver. The BI was measured with a parent report questionnaire. In the experiment the parent provided the safety and threat information for two strangers, creating two conditions. After the manipulation the fear beliefs of the child was measured for both strangers. The first analysis revealed a significant difference of the parental verbal information on fear beliefs in the condition threat versus safety. The second analyses revealed no significant moderating role of BI in this effect. The findings suggest that threat versus safety parental verbal transmission contribute to the social fear cognitions of the child of strangers. The BI temperament of the child seems not to make the child differential suspectable to the parental verbal transmission.Show less

This experimental study aims to investigate the effect of parental threatening and safe information about strangers on the fear and avoidance behavior of their child, in a non-clinical sample. It is also examined whether behavioral inhibition, parental social anxiety and their interaction lead to more socially anxious behavior of the child. Method: A sample of 68 children between 4 and 6 years old performed a social performance task in front of two strangers. Before the task, the parent was asked to transfer verbal threatening or safe information about the strangers to their child. After the task, the strangers interacted with the children separately from each other. Results: Exposure to verbal expression of threat about strangers did not change the anxious or avoidant behavior of children towards those strangers. However, the interaction of behavioral inhibition and parental social anxiety was significant, such that higher levels of behavioural inhibition in combination with less social anxiety in parents were significantly associated with more social anxiety towards the stranger about whom children receive safe information. Conclusion: Intergenerational transmission of social anxiety occurs when children who have a higher behavioral inhibition in combination with less socially anxious parents receive positive information about a stranger. It is concluded that the intergenerational transmission of social anxiety is dependent on multiple variables concerning the parents and the child.Show less
