Anxiety Symptoms in Young Children Are Associated With a Maladaptive Neurobehavioral Profile of Error Responding

BACKGROUND

Childhood anxiety symptoms have been linked to alterations in cognitive control and error processing, but the diverse findings on neural markers of anxiety in young children, which vary by severity and developmental stage, suggest the need for a wider perspective. Integrating new neural markers with established ones, such as the error-related negativity, the error positivity, and frontal theta, could clarify this association. Error-related alpha suppression (ERAS) is a recently proposed index of post-error attentional engagement that has not yet been explored in children with anxiety.

METHODS

To identify neurobehavioral profiles of anxiety in young children by integrating ERAS with the error-related negativity, error positivity, frontal theta, and post-error performance indicators, we employed K-means clustering as an unsupervised multimetric approach. For this, we first aimed to confirm the presence and scalp distribution of ERAS in young children. We performed event-related potentials and spectral analysis of electroencephalogram data collected during a Go/NoGo task (Zoo Task) completed by 181 children (ages 4-7 years; 103 female) who were sampled from across the clinical-to-nonclinical range of anxiety severity using the Child Behavior Checklist.

RESULTS

Results confirmed ERAS, showing lower post-error alpha power, maximal suppression at occipital sites, and less ERAS in younger children. K-means clustering revealed that high anxiety and younger age were associated with reduction in ERAS and frontal theta, less negative error-related negativity, enlarged error positivity, more post-error slowing, and reduced post-error accuracy.

CONCLUSIONS

Our findings indicate a link between ERAS, maladaptive neural mechanisms of attention elicited by errors, and anxiety in young children, suggesting that anxiety may arise from or interfere with attention and error processing.

Mitigating Multiple Sources of Bias in a Quasi-Experimental Integrative Data Analysis: Does Treating Childhood Anxiety Prevent Substance Use Disorders in Late Adolescence/Young Adulthood?

Psychiatric epidemiologists, developmental psychopathologists, prevention scientists, and treatment researchers have long speculated that treating child anxiety disorders could prevent alcohol and other drug use disorders in young adulthood. A primary challenge in examining long-term effects of anxiety disorder treatment from randomized controlled trials is that all participants receive an immediate or delayed study-related treatment prior to long-term follow-up assessment. Thus, if a long-term follow-up is conducted, a comparison condition no longer exists within the trial. Quasi-experimental designs (QEDs) pairing such clinical samples with comparable untreated epidemiological samples offer a method of addressing this challenge. Selection bias, often a concern in QEDs, can be mitigated by propensity score weighting. A second challenge may arise because the clinical and epidemiological studies may not have used identical measures, necessitating Integrative Data Analysis (IDA) for measure harmonization and scale score estimation. The present study uses a combination of propensity score weighting, zero-inflated mixture moderated nonlinear factor analysis (ZIM-MNLFA), and potential outcomes mediation in a child anxiety treatment QED/IDA (n = 396). Under propensity score-weighted potential outcomes mediation, CBT led to reductions in substance use disorder severity, the effects of which were mediated by reductions in anxiety severity in young adulthood. Sensitivity analyses highlighted the importance of attending to multiple types of bias. This study illustrates how hybrid QED/IDAs can be used in secondary prevention contexts for improved measurement and causal inference, particularly when control participants in clinical trials receive study-related treatment prior to long-term assessment.

Prevalence, comorbidities and mediators of childhood anxiety disorders in urban Turkey: a national representative epidemiological study

PURPOSE

The aim of this study is to evaluate the prevalence of anxiety disorders, its correlation with sociodemographic characteristics, its comorbidities with other psychiatric disorders and its predictors in school-aged children.

METHODS

This study is part of a representative, multi-centered national study that is planned by the Turkish Association of Child and Adolescent Mental Health to evaluate the prevalence of psychopathology among elementary school students in Turkey between the years 2014-2015. Children are screened via Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version. Impairment is assessed by a 3-point Likert type scale independently by the parent and the teacher. The final sample included 5842 children with the mean age of 8.7 years.

RESULTS

The prevalence of any anxiety disorder without considering impairment is 16.7% and considering impairment is 5.2% in children according to our study. We found significant differences for comorbid Attention Deficit Hyperactivity Disorder, Disruptive Behavior Disorder, Mood Disorders, Tic Disorders, Obsessive Compulsive Disorder, Enuresis Nocturna, Encopresis, and Intellectual Disability. Having a history of paternal physical disorder, living in the regions of Marmara, Mediterranean and Black Sea were found to be the main predictors of having childhood anxiety disorders according to the logistic regression analysis.

CONCLUSION

Better understanding of childhood anxiety disorders, comorbid conditions and predictors will result in earlier diagnosis and more appropriate treatment.

Development and validation of the Modeling of Parental Anxiety Questionnaire

Parental anxious modeling is assumed to be a risk factor for child anxiety. Until now there has been no self-assessment scale available that measures parental modeling of anxiety in a comprehensive way. Our aim with this study was to bridge this gap by developing the Modeling of Parental Anxiety Questionnaire (MPAQ). To do this, we generated an item pool containing 51 statements covering different aspects of parental modeling of anxious and non-anxious behaviors. A sample of Swedish parents (N = 1092) of children aged 4-12, answered an online survey comprising the generated item pool, the Parental Overprotection Scale (OP) and the PROMIS Anxiety short forms (the adult version and the parent proxy report scale). A factor analysis of the items of parental modeling indicated a structure with four separate factors. These factors formed the final four subscales of MPAQ; (1) being curios and content, (2) being on guard, (3) displaying anxiety and avoidance, and (4) displaying stress. The Cronbach's alpha coefficients of the subscale scores ranged from moderate to good. Linear regression analysis showed that the displaying anxiety and avoidance-subscale had the strongest association with child anxiety symptoms. These findings show that MPAQ demonstrates adequate psychometric properties and has potential for being used in research and clinical settings, for example to identify potential targets for parenting interventions and to measure mediation effects.

Preliminary examination of reliability and validity of the Japanese child anxiety impact scale-parent version in Japanese community sample

The child anxiety impact scale-parent version (CAIS-P) is a useful measure to assess the impact of anxiety on a child's daily life; however, a Japanese version of the CAIS-P has not been developed, and whether the CAIS-P can be utilized in Eastern countries remains unascertained. The purpose of this study was to develop a Japanese version of the CAIS-P and examine its reliability and validity. Parents of 400 children (aged 7 to 15 years) from the Japanese community completed the CAIS-P. A confirmatory factor analysis indicated that the factor structure of the original CAIS-P, consisting of school activity, social activity, and home/family activity factors, provided a good fit for the Japanese version of the CAIS-P. Estimated Spearman's correlation coefficients showed moderate correlations between the total and factor scores of the CAIS-P, anxiety symptoms (Spence Child Anxiety Scale-parent version), and depressive symptoms (Child Depression Inventory). Furthermore, the item response theory model revealed that each factor of the CAIS-P is a high information reliable measure for children with high trait anxiety. These results provide support for the Japanese version of the CAIS-P's factorial validity, convergent validity, and reliability and its potential for application in child anxiety research in Japan.

The Role of Social Skills in Predicting Treatment-Recovery in Children with a Social Anxiety Disorder

The current study investigated the role of social skills and its interaction with social anxiety as predictors of treatment outcome in children with an anxiety disorder either with or without a social anxiety disorder (SoAD). In total, 133 children (aged 8 to 13) with an anxiety disorder received a 10-session cognitive behavioral treatment (FRIENDS program). Pre- to post treatment Reliable Change (RC) and Treatment-Recovery (TR) were assessed from a multi-informant perspective, by including diagnostic information (ADIS C/P), child-reported anxiety symptoms (MASC) and parent-reported internalizing symptoms (CBCL-Int). Social skills were assessed with the parent-rated Social Skills Rating System (assertion, self-control, responsibility). Results showed that 1) parents of children with a SoAD reported significantly less favorable use of assertive and responsible social behavior in their children pre-treatment than parents of children without SoAD, 2) children with higher social skills had a better treatment recovery, and 3) children with anxiety and higher responsible behavior pre-treatment and without a SoAD had a better treatment recovery, but this effect did not show for children with SoAD. In conclusion, better use of social behavior increased the likelihood of treatment recovery but not of reliable change. Further studies on the role of social skills in the treatment of childhood (social) anxiety are needed to investigate the mechanisms by which social skills impact treatment outcome.

Childhood Anxiety: Prenatal Maternal Stress and Parenting in the QF2011 Cohort

In this study we examine whether specific 'anxiety-maintaining' parenting behaviors (i.e., overinvolvement and/or negativity) exacerbate the effects of disaster-related prenatal maternal stress (PNMS) on school-age anxiety symptoms. Women (N = 230), pregnant at the time of the 2011 Queensland Floods, reported on their experience of flood-related PNMS (objective hardship, cognitive appraisal, subjective distress). At 4-years, mother-child dyads were coded for maternal overinvolvement and negativity during a challenging task; at 6-years mothers reported on their children's anxiety symptoms and their own mood, N = 83. Results showed no associations between PNMS and 6-year anxiety, nor did parenting moderate these effects. Poorer maternal concurrent mood was associated with greater anxiety symptoms at 6 years (β = 0.52). Findings suggest maternal concurrent mood, but not exposure to disaster-related PNMS nor 'anxiety-maintaining' parenting behaviors at preschool age, is related to school-age anxiety symptoms.

Disaster-related prenatal maternal stress, and childhood HPA-axis regulation and anxiety: The QF2011 Queensland Flood Study

BACKGROUND

The fetal programming hypothesis suggests that prenatal maternal stress (PNMS) influences aspects of fetal development, such as the Hypothalamic Pituitary Adrenal (HPA) axis, enhancing susceptibility to emotional problems. No study (to our knowledge) has investigated this pathway considering development of preschool anxiety symptoms. Using data from the Queensland Flood study (QF2011), our objective was to determine whether toddler HPA-axis functioning mediated the association between aspects of flood-related PNMS and child anxiety symptoms at 4-years, and whether relationships were moderated by the timing of the stressor in utero or by the child's sex.

METHODS

Women, pregnant during the 2011 Queensland floods (N = 230), were recruited soon afterwards and completed questionnaires regarding their objective hardship (e.g., loss of personal property), subjective distress (post-traumatic-like symptoms) and cognitive appraisal of the disaster. At 16 months, indexes of the child's diurnal cortisol rhythm (awakening response, total daily output, diurnal slope [N = 80]), and stress reactivity (N = 111), were obtained. At 4-years, N = 117 mothers reported on their own mood and their children's anxiety symptoms; of these, N = 80 also had valid child cortisol reactivity data, and N = 64 had diurnal cortisol rhythm data.

RESULTS

A greater cortisol awakening response at 16 months mediated the relationship between subjective PNMS and anxiety symptoms at 4-years. Greater toddler daily cortisol secretion predicted more anxiety symptoms, independent of PNMS. The laboratory stressor did not elicit a cortisol response. PNMS effects were not dependent upon child sex nor on gestational timing of flood exposure.

CONCLUSIONS

Indexes of diurnal cortisol in toddlerhood may represent vulnerability for anxiety symptoms in preschoolers, both independent of, and following, exposure to disaster-related prenatal maternal subjective distress.

Content-Specific Interpretation Bias in Children with Varying Levels of Anxiety: The Role of Gender and Age

The current study examined whether children varying in their levels of social anxiety, separation anxiety and spider fear exhibit a negative interpretation bias specific for their fears. Furthermore, age and gender were assessed as moderators of this relation. Children (N = 603) of the age of 7-12 years were asked to solve ambiguous scenarios reflecting social threat, separation threat or spider threat. Children's levels of anxiety were assessed with self-report questionnaires. Results indicated that children scoring higher on self-reported social anxiety, separation anxiety or spider fear, displayed a negative interpretation bias for the threat-scenarios pertaining to their specific anxiety or fear, even after controlling for comorbidity with other anxiety subtypes. Contrary to our hypotheses, we did not find moderating effects of age or gender. These results indicate that even in a community sample, content-specificity of negative interpretation biases is present.

Cognitive Behavior Therapy and Metacognitive Therapy: Moderators of Treatment Outcomes for Children with Generalized Anxiety Disorder

Although cognitive behavioral therapy (CBT) is effective for childhood anxiety disorders, approximately 40% of youth remain anxious after treatment. Metacognitive therapy (MCT-c) for children with generalized anxiety disorder (GAD) has shown promising effects. The present study aimed to examine if CBT and MCT-c show differential effects in children with primary GAD based on baseline characteristics, in a quasi-experimental design. To investigate which treatment is most beneficial for whom, three potential moderators: age, symptom severity, and comorbid social anxiety were examined. Sixty-three children aged 7-14 completed CBT or MCT-c. Participants were assessed before and after treatment. Both CBT and MCT-c were highly effective in treatment of childhood GAD. None of the selected variables significantly moderated treatment outcomes. Subgroups of children with high symptom severity and social anxiety comorbidity showed trends of responding better to CBT. Methodologically stronger studies are needed to facilitate a better adaptation of treatment for children with GAD.

Parental Involvement in Cognitive Behavior Therapy for Children with Anxiety Disorders: 3-Year Follow-Up

Parental factors have been linked to childhood anxiety, hence, parental involvement in cognitive behavioral therapy (CBT) for anxious children has been examined. However, findings do not consistently show added effects of parent-enhanced CBT, longitudinal investigations are scarce and long-term effects unclear. In the present study, 40 out of 54 families who, 3 years previously, completed one of two types of CBT treatment: with limited or active parental involvement, were assessed using semi-structured diagnostic interviews. Diagnostic status at 3-years follow-up was compared between groups. Changes in diagnostic status across assessment points: posttreatment, 6-month and 3-year follow-up were analyzed within groups. Diagnostic change from 6-month to 3-year follow-up was compared between groups. Intent-to-treat analyses revealed no significant difference in diagnostic status between groups at 3-year follow-up. Nonetheless, children whose parents actively participated in treatment showed significantly more remission from 6-month to 3-year follow-up than children with limited parental participation.

Parental Meta-Emotion Philosophy and Emotion Coaching in Families of Children and Adolescents with an Anxiety Disorder

Using a multi-method approach, this study examined differences in parental meta-emotional philosophy (including, parental emotional awareness and emotion coaching) for families with anxiety disordered (AD; n = 74) and non-AD (n = 35) children (aged 7 to 15). Further, it was investigated whether children's emotion regulation (ER) varied across the AD and non-AD groups. Parent(s) were interviewed about their awareness of emotions and emotion coaching; completed a battery of questionnaires that included a measure assessing children's emotion regulation; and engaged in a parent-child discussion task. Results indicated that compared to parents of non-AD youth, parents of AD youth were less aware of their own emotions and their children's emotions, and these results varied by emotion type. Parents of AD youth engaged in significantly less emotion coaching than parents of non-AD youth. AD youth were identified as having significantly greater difficulty regulating their emotions when compared to non-AD youth. Implications for the role of parental meta-emotional philosophy and AD youth's emotion regulation are discussed.

The risk and protective factors in the development of childhood social anxiety symptoms among Chinese children

The aim of this study was to explore the change and associated risk and protective factors of social anxiety symptoms among Chinese children. A 2-year longitudinal study was performed in a general primary and secondary school population in Anhui Province, China including 816 children in grades 3, 4, and 7. Children's social anxiety symptoms were assessed using the Social Anxiety Scales for Children (SASC) at three assessments. The overall prevalence of children's elevated social anxiety symptoms ranged from 15.2% to 16.4% across three assessments. Children's overall mean SASC scores were 5.6 (SD =3.7), 5.3 (SD =3.8), and 5.3 (SD =4.1) at three assessments, respectively, but the difference was not statistically significant. However, children's social anxiety symptom levels and change among different subgroups was not stable across 2-year follow-up. Multivariable logistic regression analysis indicated that age, severe family dysfunction, quality of life, positive coping, negative coping, depressive symptoms and self-esteem were predictive factors for childhood elevated social anxiety symptoms. The findings suggested that the overall social anxiety symptoms showed a relatively stable pattern over time. The identified risk and protective factors may provide scientific evidence for school, family, and health authorities to conduct necessary intervention.

Relations Between Parental and Child Separation Anxiety: The Role of Dependency-Oriented Psychological Control

Although separation anxiety is prevalent in young children, it remains unclear whether and how maternal separation anxiety is related to separation anxiety in children. This study examined associations between maternal separation anxiety and separation anxiety in children, and the potential effect psychologically controlling parenting. Mothers (N = 269) and children (N = 287) recruited for a community sample participated in two 1-year interval data-waves. Children were aged five-eight and were interviewed using an age-appropriate method for obtaining self-reports of separation anxiety and perceptions of dependency-oriented psychologically controlling parenting. Mothers reported on their feelings of separation anxiety regarding their child via a questionnaire. We found that maternal separation anxiety was positively related to separation anxiety in children within, but not over time. We did not find psychologically controlling parenting to mediate this association. Studying other factors than parenting may be an important avenue for future research in explaining separation anxiety in children.

Responses to voluntary hyperventilation in children with separation anxiety disorder: implications for the link to panic disorder

BACKGROUND

Biological theories on respiratory regulation have linked separation anxiety disorder (SAD) to panic disorder (PD). We tested if SAD children show similarly increased anxious and psychophysiological responding to voluntary hyperventilation and compromised recovery thereafter as has been observed in PD patients.

METHODS

Participants were 49 children (5-14 years old) with SAD, 21 clinical controls with other anxiety disorders, and 39 healthy controls. We assessed cardiac sympathetic and parasympathetic, respiratory (including pCO2), electrodermal, electromyographic, and self-report variables during baseline, paced hyperventilation, and recovery.

RESULTS

SAD children did not react with increased anxiety or panic symptoms and did not show signs of slowed recovery. However, during hyperventilation they exhibited elevated reactivity in respiratory variability, heart rate, and musculus corrugator supercilii activity indicating difficulty with respiratory regulation.

CONCLUSIONS

Reactions to hyperventilation are much less pronounced in children with SAD than in PD patients. SAD children showed voluntary breathing regulation deficits.
