Stressed Out! : Stress physiology in anxious children
Anxiety is a basic emotion, not typically pathologic but commonly adaptive when it facilitates anticipation to a threat or danger. However, when children perceive the world as full of threats and dangers, with no possibility to relax and to regard their living environment as safe, anxiety becomes pathologic. Variations in the activity of the hypothalamic-pituitary-adrenal (HPA) axis and the autonomic nervous system (ANS), two major physiological stress systems, have been implicated
as possible biological markers of pathological anxiety in children. Normally, activation of these stress systems leads to behavioral
and physical adaptive changes that improve an organism’s ability to survive. In children with an anxiety disorder, the persistent stress they experience might lead to an excessive and prolonged stress system activation.
In summary, this thesis focused on the role of stress physiology as a cause, correlate, and predictor of pediatric anxiety disorders with the ultimate goal to improve treatment and prognosis. The results of the studies described in this thesis suggest that stress physiology is a biological marker for the onset, severity, and course of anxiety problems in childhood. Altered physiological functioning of the stress systems, as a vulnerability factor, could influence the expression of clinical anxiety disorders. In addition, chronic and pathological anxiety problems, interfering with daily life and leading to a clinical anxiety disorder, have a different effect on physiological functioning than temporarily heightened, subclinical anxiety symptoms

Threat-Related Selective Attention Predicts Treatment Success in Childhood Anxiety Disorders
Abstract
OBJECTIVE: The present study examined whether threat-related selective attention was predictive of treatment success in children with anxiety disorders and whether age moderated this association. Specific components of selective attention were examined in treatment responders and nonresponders.
METHOD: Participants consisted of 131 children with anxiety disorders (aged 8-16 years), who received standardized cognitive-behavioral therapy. At pretreatment, a pictorial dot-probe task was administered to assess selective attention. Both at pretreatment and posttreatment, diagnostic status of the children was evaluated with a semistructured clinical interview (the Anxiety Disorders Interview Schedule for Children).
RESULTS: Selective attention for severely threatening pictures at pretreatment assessment was predictive of treatment success. Examination of the specific components of selective attention revealed that nonresponders showed difficulties to disengage their attention away from severe threat. Treatment responders showed a tendency not to engage their attention toward severe threat. Age was not associated with selective attention and treatment success.
CONCLUSIONS: Threat-related selective attention is a significant predictor of treatment success in children with anxiety disorders. Clinically anxious children with difficulties disengaging their attention away from severe threat profit less from cognitive-behavioral therapy. For these children, additional training focused on learning to disengage attention away from anxiety-arousing stimuli may be beneficial
Developmental Trajectories of Anxiety and Depression Symptoms from Early to Middle Childhood:a Population-Based Cohort Study in the Netherlands
Feasibility of Dried Blood Spots in Children with Behavioral Problems
BACKGROUND: Minimally invasive sampling methods are important to facilitate therapeutic drug monitoring and pharmacokinetic research in children with behavioral problems. This study assessed the feasibility and pain of dried blood spot (DBS) sampling in this population. METHODS: Repeated DBS sampling was performed in children with autism spectrum disorder (ASD) and severe behavioral problems using antipsychotic drugs, aged between 6 and 18 years. The child, guardian, and DBS performer assessed pain using the numeric rating scale (NRS-11) or 5-face Faces Pain Scale. The influence of age, sex, and the fingerprick performer on the child's pain intensity was analyzed using linear mixed models. RESULTS: Overall, 247 fingerpricks were performed in 70 children. Seven children refused all DBS sampling. The median (interquartile range) NRS-11 pain scores were 2 (3) rated by children, 3 (2.5) by guardians, and 2 (2) by fingerprick performers. The child's age and sex, and fingerprick performer had no significant influence on pain intensity. CONCLUSIONS: DBS sampling could be performed in most children with ASD and severe behavioral problems. However, 1 in 5 children refused one or more DBS fingerpricks owing to distress. Most expressed minimal pain (NRS < 4). Repeated sampling with DBS is feasible in children with ASD and severe behavioral problems
Cognitive Behavioural Therapy for Anxiety Disorders in Young Children: A Dutch Open Trial of the Fun FRIENDS Program
Anxiety disorders in young children are highly prevalent and increase the risk of social, school, and familial problems, and also of psychiatric disorders in adolescence and adulthood. Nevertheless, effective interventions for this age group are lacking. One of the few available interventions is the Fun FRIENDS
program. We examined whether young children with anxiety disorders showed less anxiety after participating in Fun FRIENDS. Twenty-eight clinically anxious children (4–8 years old) participated in the cognitive behavioural Fun FRIENDS program. The program consists of 12 weekly 1.5-hour sessions and was
provided in groups of 3 to 5 children. At preintervention and direct postintervention, parents completed
the Anxiety Disorders Interview Schedule for Children and Child Behavior Checklist. Clinically and statistically significant decreases were found in number of anxiety disorders, symptom interference, emotional
and behavioural problems, internalising problems, and anxiety problems. The decrease in anxious/
depressed problems and externalising problems was not significant. Furthermore, higher preintervention
anxiety levels predicted more treatment progress, whereas sex and age did not. The Dutc
