A Meta-analytic Review of the Role of Child Anxiety Sensitivity in Child Anxiety

Child's Play: Examining the Association Between Time Spent Playing and Child Mental Health

It is theorised that adventurous play offers learning opportunities that help to prevent mental health problems in children. In this study, data from two samples is used to examine associations between the time that children aged 5-11 years spent playing adventurously and their mental health. For comparison, time spent playing unadventurously and time spent playing outdoors are also examined. Study 1 includes a sample of 417 parents, Study 2 includes data from a nationally representative sample of 1919 parents. Small, significant associations between adventurous play and internalising problems, as well as positive affect during the first UK-wide Covid-19 lockdown, were found; children who spend more time playing adventurously had fewer internalising problems and more positive affect during the Covid-19 lockdown. Study 2 showed that these associations were stronger for children from lower income families than for children from higher income families. The results align with theoretical hypotheses about adventurous play.

Cognitive Behavioral Therapy for Children and Adolescents with Anxiety Disorders

Anxiety disorders are the most common class of psychiatric conditions among children and adolescents. The cognitive behavioral model of childhood anxiety has a strong theoretic and empirical foundation that provides the basis for effective treatment. Cognitive behavioral therapy (CBT), with an emphasis on exposure therapy, is the gold standard treatment for childhood anxiety disorders, with strong empirical support. A case vignette demonstrating CBT for childhood anxiety disorders in practice, as well as recommendations for clinicians, are also provided.

Intensive Cognitive-Behavioral Therapy for Anxiety Disorders in Adolescents: A Case Study

Anxiety disorders are one of the most common psychiatric conditions in youth and can contribute to impairment in social, academic, and family functioning. Cognitive-behavioral therapy (CBT) has been shown to be efficacious in treating youth anxiety disorders; however, for a multitude of reasons, fewer than 20% of adolescents with anxiety disorders receive services for anxiety-related problems. Intensive treatments, which rely on the same traditional components of CBT but are delivered over a shorter period of time or in a fewer number of sessions, may be particularly helpful for anxiety disorders and can offer a number of advantages over standard CBT. Despite emerging evidence supporting the advantages of the intensive approach, there are few established intensive treatment programs for youth with anxiety disorders. Further, no treatment to date has comprehensively targeted the entire spectrum of comorbid adolescent anxiety disorders in a combined intensive and transdiagnostic format, even though non-intensive (i.e., weekly delivered) CBT has been tested using a transdiagnostic approach. We developed an intensive, six-session intervention based on Angelosante and colleagues’ 2009 The Adolescent Panic Control Treatment with In-Vivo Exposures (Angelosante et al., 2009) and other empirically-supported treatments for youth to target all anxiety disorders in adolescents. We present a case study on an adolescent with multiple comorbid anxiety and related disorders who received intensive CBT treatment as a way to illustrate the clinical benefit and utility of an intensive, transdiagnostic approach. Findings support the acceptability and feasibility of transdiagnostic treatment of youth anxiety.

Risk Factors Associated With Increased Anxiety Sensitivity in Children and Adolescents in Northwest China During COVID-19 Pandemic Lockdown

Purpose

A large body of evidence has revealed that the sudden outbreak of public health emergencies induces dramatic effects on the mental health of the general public. We aimed to investigate the level of anxiety sensitivity and its risk factors in children and adolescents from northwest China during the COVID-19 pandemic lockdown in early 2020.

Methods

A cross-sectional survey was conducted through the Wenjuanxing platform using a convenience sampling method between 18 and 26 February 2020. The self-designed questionnaire contained sociodemographic characteristics, factors associated with the COVID-19 pandemic, and the Childhood Anxiety Sensitivity Index (CASI) scale. The data from 1,091 valid questionnaires from students aged 9–17 years were analyzed using ANOVA, multiple linear regression, and binary logistic regression.

Results

The average CASI scores were 11.47 ± 6.631, and 642 students (58.9%) had prominent anxiety sensitivity. Gender, education level, family members participating in anti-COVID-19 work, getting ill and needing medical help during the lockdown, feeling afraid or having heart palpitations on hearing things associated with COVID-19, believing that COVID-19 would have adverse impacts on themselves or their family in the future, and fear of infection were identified as significant factors for elevated levels of anxiety sensitivity (p < 0.05). We established a multiple linear regression model for the anxiety sensitivity score. Risk factors found for anxiety sensitivity in children and adolescents during the COVID-19 lockdown included studying in secondary or high school, becoming ill during the pandemic, feeling afraid or experiencing rapid heartbeat or palpitations on hearing about the COVID-19 pandemic, thinking that COVID-19 would have an adverse impact on themselves or their family in the future, and fear of infection.

Conclusions

During the COVID-19 pandemic and home quarantine, scores measuring the prevalence of anxiety sensitivity in children and adolescents from northwest China were elevated. We should develop measures that especially target possible risk factors to intervene against and prevent anxiety sensitivity in children and adolescents in both the current and future pandemics.

Ethical concerns relating to genetic risk scores for suicide

Genome-wide association studies (GWAS) provide valuable information in research contexts regarding genomic changes that contribute to risks for complex psychiatric conditions like major depressive disorder. GWAS results can be used to calculate polygenic risk scores (PRS) for psychiatric conditions, such as bipolar disorder or schizophrenia, as well as for other traits, such as obesity or hypertension. Private companies that provide direct-to-consumer (DTC) genetic testing sometimes report PRS for a variety of traits. Recently, the first well-powered GWAS study for suicide death was published. PRS reports that claim to assess suicide risk are therefore likely to appear soon in the DTC setting. We describe ethical concerns regarding the commercial use of GWAS results related to suicide. We identify several issues that must be addressed before PRS for suicide risk is made available to the public through DTC: (a) the potential for misinterpretation of results, (b) consumers' perceptions about determinism and behavior change, (c) potential contributions to stigma, discrimination, and health disparities; and (d) ethical problems regarding the testing of children and vulnerable adults. Tests for genetic prediction of suicidality may eventually have clinical significance, but until then, the potential for individual and public harm significantly outweighs any potential benefit. Even if genetic prediction of suicidality improves significantly, information about genetic risk scores must be distributed cautiously, with genetic counseling, and with adequate safeguards.

Cognitive vulnerabilities to anxiety symptoms among Chinese adolescents: A 3-year longitudinal study

OBJECTIVE

This study established cognitive vulnerability of anxiety symptoms among high school students.

METHOD

A total of 72 grade 9-11 students completed measures on levels of anxiety sensitivity (AS), selective attentional processing, and anxiety symptoms annually between 2016 and 2018.

RESULTS

Latent class growth analysis (unconditional model) showed a four-class model: High (stable) (6.94%), low (stable) (11.11%), medium (decreasing) (61.11%), and medium (increasing) (20.83%). The conditioned model controlling for the physical-concerns dimension of AS and negative attentional bias demonstrated that a two-class model consisted of a low anxiety class (n = 59, 81.9%) and a high anxiety class (n = 13, 18.1%) provided the best fit for the data. Negative attentional bias is a significant factor related to the development of anxiety trajectories.

CONCLUSION

Attentional bias modification to disengage from negative stimuli may serve as a potential target of intervention to reduce chronic anxiety among high school students.

Effects of anxiety sensitivity on cannabis, alcohol, and nicotine use among adolescents: evaluating pathways through anxiety, withdrawal symptoms, and coping motives

Anxiety sensitivity (AS) is a promising intervention target due to its relevance to negative health behaviors broadly, and substance use specifically. The aim of the current study was to evaluate the direct and indirect pathways through which elevated AS could relate to recent substance use among a national adolescent sample recruited via social-media. As predicted, AS was indirectly associated with greater likelihood of using alcohol, cigarettes, and electronic nicotine delivery systems in the past-month through anxiety symptoms. Regarding cannabis, AS was directly related to increased likelihood of past-month cannabis use; however, the indirect relation between AS and likelihood of past-month use via anxiety symptoms was not significant. Through chained indirect effects, AS was related positively to past-month alcohol and cannabis use via anxiety symptoms and coping-related motives, and through withdrawal symptoms and coping-related motives. Study findings can be used to generate hypotheses on potential pathways through which AS could prospectively relate to substance use among youth.

Adventurous Play as a Mechanism for Reducing Risk for Childhood Anxiety: A Conceptual Model

In this conceptual article, we draw upon the literature regarding cognitive and behavioural factors that underpin childhood anxiety to outline how a range of these risk markers might be targeted through adventurous play. When children play in an adventurous way, climbing trees, riding their bikes fast downhill and jumping from rocks, they experience feelings of fear and excitement, thrill and adrenaline. We propose that the positive, thrilling and playful emotions associated with this type of child-led play facilitate exposure to fear-provoking situations and, in doing so, provide opportunities for children to learn about physiological arousal, uncertainty and coping. We hypothesise that these learning opportunities will, over time, reduce children's risk for elevated anxiety by increasing children's expectations and ability to cope with anxiety, decreasing intolerance of uncertainty and preventing catastrophic misinterpretations of physiological arousal. If our conceptual model is correct, then ensuring that children have the physical and psychological space required to play in an adventurous way may help to decrease their risk for elevated or clinical anxiety.

Relationship of affect intolerance with anxiety, depressive, and obsessive-compulsive symptoms in youth

BACKGROUND

Structural research on the construct of affect intolerance (an overarching latent construct indicated by distress tolerance and anxiety sensitivity) has only been conducted in adults. Given that a self-report measure of distress tolerance was recently validated for youth and affect intolerance may be a core mechanism of transdiagnostic interventions for internalizing disorders, we examined how affect intolerance relates to internalizing symptoms in youth. We predicted that a latent affect intolerance factor (indicated by distress tolerance and anxiety sensitivity) would be associated with self and parent-reports of youth anxiety, depressive, and obsessive-compulsive symptoms, controlling for age and gender.

METHODS

At a pre-treatment evaluation, youth with a primary depressive, anxiety, or obsessive-compulsive spectrum disorder (N=277) aged 8-17, and their parent, completed questionnaires.

RESULTS

Greater levels of the affect intolerance factor predicted greater youth- and parent-reported youth anxiety, depression, and obsessive-compulsive symptoms, controlling for age.

LIMITATIONS

Future research should replicate findings in a sample with a greater proportion of depressed youth and utilize experimental or longitudinal methods.

CONCLUSIONS

Importantly, distress tolerance and anxiety sensitivity are core transdiagnostic processes that can be targeted in cognitive-behavioral interventions. Future research should examine how transdiagnostic interventions for youth with internalizing disorders can target these cross-cutting emotional vulnerabilities.

Emotion regulation abilities as a predictor of anxiety, positive emotions, heart rate, and alpha asymmetry during an impromptu speech task

BACKGROUND AND OBJECTIVES

Recent approaches suggest that emotion regulation (ER) abilities represent potential predictors of emotional response among youths navigating stressful situations. To test this, we investigated whether ER abilities predicted the subjective and physiological emotional response experienced by youths during a stressful situation.

DESIGN

A cross-sectional design was employed.

METHOD

One hundred and thirty-four youths completed measures of ER abilities (emotional awareness, anxiety sensitivity, emotional control) and were asked to deliver a speech while their anxiety, positive emotions, heart rate, and alpha asymmetry were collected at four time points: baseline, anticipation, speech, and post-recovery.

RESULTS

Pearson r correlations showed that poor emotional control and awareness, as well as high anxiety sensitivity were related to greater anxiety and lower positive emotions experienced during the speech. Hierarchical multiple regressions also revealed that emotional control and emotional awareness predicted greater speech anxiety and lower positive emotions. Moreover, anxiety sensitivity was related to and predicted an increased heart rate experienced during speech.

CONCLUSIONS

Findings suggest that difficulties in emotional awareness, anxiety sensitivity, and emotional control predict the emotional response experienced by youths during a stressful situation. Interventions delivered by clinicians/teachers that target ER difficulties may be effective in improving emotional functioning when navigating stressful situations.

The Co-occurrence of Pediatric Chronic Pain and Anxiety: A Theoretical Review of a Developmentally Informed Shared Vulnerability Model

The development and maintenance of pediatric chronic pain and anxiety are complex, underscoring the need to better understand the interactive forces contributing to their co-occurrence. The shared vulnerability model (SVM) was developed to explain the co-occurrence of chronic pain and posttraumatic stress disorder in adults. Although many core tenets have been well supported by pediatric research, the SVM has yet to be extended to pediatric pain populations. We propose a developmentally informed pediatric SVM for advancing our understanding of the co-occurrence of pediatric chronic pain and anxiety disorders. The proposed SVM postulates that youth at increased risk for the development of chronic pain and/or anxiety share predisposing vulnerabilities, including anxiety sensitivity, and that these shared vulnerabilities give rise to negative emotional responses (child and parent) in the context of stressful events. Consequences of fear and anxiety, including avoidance behavior, further contribute to the development of chronic pain, anxiety, and their co-occurrence. The parental, school, and peer contexts in which these problems develop and are maintained in youth are pertinent to integrate into a SVM, as pediatric chronic pain and anxiety disorders share several social-contextual risk and maintenance factors. We also highlight new areas of inquiry.

The interaction between sleep disturbances and anxiety sensitivity in relation to adolescent anger responses to parent adolescent conflict

INTRODUCTION

Sleep disturbances are common among adolescents and are associated with elevated anxiety, and difficulties managing affect. Familial conflict is associated with both anxiety sensitivity and adolescent sleep disturbances. No work to date has examined how adolescent sleep disturbances may interact with anxiety sensitivity in relation to adolescent affective responding to parent-adolescent conflict. The current study was designed to address this gap in the literature by examining how adolescent sleep disturbances, anxiety sensitivity, conflict elicited anger, and conflict avoidance are associated.

METHOD

Seventy-two American adolescents (n = 39 males) between the ages of 12 and 16 years (M_age = 13.84, SD = 1.38) completed a baseline assessment as well as a well-validated mother-adolescent laboratory-based conflict task.

RESULTS

For youth low in anxiety sensitivity, greater sleep disturbance related positively to conflict-elicited anger, which in turn predicted higher conflict avoidance. In contrast, this indirect effect was not significant for adolescents relatively higher in anxiety sensitivity. Instead, for these adolescents, increased sleep disturbances were associated with lower levels of conflict elicited anger.

CONCLUSIONS

Results suggest that the effects of sleep disturbances on conflict elicited anger may vary as a function of adolescent anxiety vulnerability. These findings highlight the importance of considering the unique effects of sleep disturbances on adolescent affect as a function of adolescent anxiety vulnerability.

Anxiety Sensitivity and Children's Risk for Both Internalizing Problems and Peer Victimization Experiences

In this study, we examined the degree to which children's level of anxiety sensitivity (AS) was a precursor to both internalizing problems and peer victimization experiences. Participants were 581 fourth-grade children (M age = 9.31; 51.8% girls; 42.3% Hispanic/Latinx) and their teachers. Measures of AS, internalizing problems, and peer victimization were collected across a single academic year (Fall, Spring). Structural equation modeling and logistic regression analyses indicated AS predicted future internalizing symptoms as well as self- and teacher-reports of peer victimization. Also, children with heightened AS were 2.70 times more likely to reach elevated levels of self-rated peer victimization and 11.53 times more likely to have clinically elevated internalizing problems. This is the first study to examine prospectively the link between AS and children's peer victimization experiences. We discuss implications of the findings for developing preventative interventions for children at risk for peer victimization and internalizing difficulties.

Test of an Anxiety Sensitivity Amelioration Program for at-risk youth (ASAP-Y)

OBJECTIVE

Adult research supports the efficacy of targeting the malleable risk factor of anxiety sensitivity (AS) in preventing anxiety and related psychopathology. However, very little work has evaluated the impact of AS reduction among youth, which is unfortunate given adolescence is a "core risk" period in terms of disorder onset.

METHOD

The primary project aim was to test the effects of an Anxiety Sensitivity Amelioration Program for Youth (ASAP-Y) among a sample of 88 youth aged 10-14 years with elevated AS. High AS youth and a parent were randomly assigned to either the ASAP-Y, which consisted of psychoeducation and experimenter-led and parent-led exposures, or a general health information control condition.

RESULTS

Youth in the intervention condition sustained low AS levels across the intervention period, and although AS levels in both conditions decreased from baseline to the one-month assessment, this decrease was more pronounced at one-month for youth in the intervention condition. Further, significant indirect effects of condition on one-month anxiety and depression symptoms via reduced AS were detected. Homework compliance rates and self-report data support the acceptability of the ASAP-Y. Contrary to hypotheses, differences between conditions in emotional reactivity elicited using experimental psychopathology methods were not observed.

CONCLUSIONS

The current findings offer preliminary support for the ASAP-Y as an acceptable selective preventive intervention for at-risk youth, with specific anxiety- and depression-related effects through reduced AS.

Do Youth with Separation Anxiety Disorder Differ in Anxiety Sensitivity From Youth with Other Anxiety Disorders?

Studies on the relationship between separation anxiety disorder (SAD) in childhood and panic disorder (PD) in adolescence and adulthood have yielded results which suggest a common underlying vulnerability for both disorders. In this study, we examined whether one such possible vulnerability-anxiety sensitivity-differed for youth diagnosed with SAD versus other anxiety disorders. Anxiety sensitivity was assessed using the Childhood Anxiety Sensitivity Index (CASI) in 315 clinic-referred youth (ages 6-17, 113 girls). 145 children (46%) were diagnosed with one or more primary anxiety disorder, including SAD (n = 22), generalized anxiety (GAD) (n = 79), social anxiety (SocA) (n = 55), and specific phobia (SP) (n = 45). Children with SAD reported higher levels of anxiety sensitivity and fears of physical symptoms than children with SP and SocA, but not children with GAD. We speculate that children who have SAD and GAD and high anxiety sensitivity may be more vulnerable to develop PD.

The Parent Sensitivity to Child Anxiety Index

Anxiety sensitivity (AS) is the perception that anxiety symptoms and experiences have negative consequences, and has been identified as a risk factor for the development of anxiety disorders. AS has been measured in adults and in children, but to date, the construct of parent's sensitivity to their children's anxiety symptoms has not been identified, measured, or evaluated. The current study presents a novel measure of this construct, the Parent Sensitivity to Child Anxiety Index (PSCAI), and an initial evaluation of its psychometric properties. Factor analysis revealed a three-factor structure consisting of parents' concern for physical symptoms, concern of social evaluation, and fear of anxiety symptoms. The PSCAI demonstrated good internal consistency, and was positively correlated with relevant parental constructs such as parental accommodation, anxiety sensitivity, and trait anxiety. This new measurement system opens new avenues for researching the early development of anxiety disorders and the possibility for novel targeted interventions.

Emotional Competence and Anxiety in Childhood and Adolescence: A Meta-Analytic Review

Anxiety is conceptualized as a state of negative emotional arousal that is accompanied by concern about future threat. The purpose of this meta-analytic review was to evaluate the evidence of associations between emotional competence and anxiety by examining how specific emotional competence domains (emotion recognition, emotion expression, emotion awareness, emotion understanding, acceptance of emotion, emotional self-efficacy, sympathetic/empathic responses to others' emotions, recognition of how emotion communication and self-presentation affect relationships, and emotion regulatory processes) relate to anxiety in childhood and adolescence. A total of 185 studies were included in a series of meta-analyses (N's ranged from 573 to 25,711). Results showed that anxious youth are less effective at expressing (r = -0.15) and understanding emotions (r = -0.20), less aware of (r = -0.28) and less accepting of their own emotions (r = -0.49), and report less emotional self-efficacy (r = -0.36). More anxious children use more support-seeking coping strategies (r = 0.07) and are more likely to use less adaptive coping strategies including avoidant coping (r = 0.18), externalizing (r = 0.18), and maladaptive cognitive coping (r = 0.34). Emotion acceptance and awareness, emotional self-efficacy, and maladaptive cognitive coping yielded the largest effect sizes. Some effects varied with children's age. The findings inform intervention and treatment programs of anxiety in youth and identify several areas for future research.

Longitudinal investigation of anxiety sensitivity growth trajectories and relations with anxiety and depression symptoms in adolescence

Anxiety sensitivity (AS), the belief that anxious arousal is harmful, is a malleable risk factor that has been implicated in anxiety and depression symptoms in adolescents. Although there is some evidence that adolescents possess distinct developmental trajectories, few studies have explored this topic. This study examined the developmental trajectory of AS in 248 adolescents (M age = 11.0 years, SD = 0.82; 56% male) across 6 years, beginning when children were age 11. This study also examined the influence of AS trajectories on anxiety and depression at age 16. Finally, this study examined the utility of AS classes in identifying anxiety and depression growth. Three AS classes were found, described by normative-stable, high-stable, and high-unstable trajectories. Adolescents in the high-stable and the high-unstable AS classes had higher levels of anxiety and depression at age 16 than did adolescents in the normative-stable AS class. In addition, the anxiety and depression trajectories fit by AS class mirrored the AS class trajectories. These findings suggest three AS trajectories can be identified in adolescents. These trajectories are discussed in relation to a developmental perspective of AS.

A multivariate twin study of trait mindfulness, depressive symptoms, and anxiety sensitivity

BACKGROUND

Mindfulness-based therapies have been shown to be effective in treating depression and reducing cognitive biases. Anxiety sensitivity is one cognitive bias that may play a role in the association between mindfulness and depressive symptoms. It refers to an enhanced sensitivity toward symptoms of anxiety, with a belief that these are harmful. Currently, little is known about the mechanisms underpinning the association between mindfulness, depression, and anxiety sensitivity. The aim of this study was to examine the role of genetic and environmental factors in trait mindfulness, and its genetic and environmental overlap with depressive symptoms and anxiety sensitivity.

METHODS

Over 2,100 16-year-old twins from a population-based study rated their mindfulness, depressive symptoms, and anxiety sensitivity.

RESULTS

Twin modeling analyses revealed that mindfulness is 32% heritable and 66% due to nonshared environmental factors, with no significant influence of shared environment. Genetic influences explained over half of the moderate phenotypic associations between low mindfulness, depressive symptoms, and anxiety sensitivity. About two-thirds of genetic influences and almost all nonshared environmental influences on mindfulness were independent of depression and anxiety sensitivity.

CONCLUSIONS

This is the first study to show that both genes and environment play an important role in the etiology of mindfulness in adolescence. Future research should identify the specific environmental factors that influence trait mindfulness during development to inform targeted treatment and resilience interventions. Shared genetic liability underpinning the co-occurrence of low mindfulness, depression, and anxiety sensitivity suggests that the biological pathways shared between these traits should also be examined.

Developmental trajectories of anxiety symptoms in early adolescence: the influence of anxiety sensitivity

Children and adolescents seem to suffer from anxiety disorders at rates similar to adults. Interestingly, anxiety symptoms appear to generally decline over time within children as evidenced by lower rates in early and middle adolescence. There is some evidence that there may be heterogeneous subpopulations of adolescent children with different trajectories of anxiety symptoms, including a class of adolescents with elevated levels of anxiety that do not dissipate over time. Anxiety sensitivity has been identified as an important risk factor in the development of anxiety psychopathology. This study prospectively examined the development of anxiety symptoms in a sample of 277 adolescents (M age = 11.52; 44 % female, 56 % male) over a 3 year period including the influence of anxiety sensitivity on this development. Further, this study investigated whether there were distinct classes of adolescents based on their anxiety symptom trajectories and including anxiety sensitivity as a predictor. Consistent with other reports, findings indicated an overall decline in anxiety symptoms over time in the sample. However, three classes of adolescents were found with distinct anxiety symptom trajectories and anxiety sensitivity was an important predictor of class membership. Adolescents with elevated anxiety sensitivity scores were more likely to be classified as having high and increasing anxiety symptoms over time versus having moderate to low and decreasing anxiety symptoms over time. There are important implications for identification of adolescents and children who are at risk for the development of an anxiety disorder.

Cognitive Vulnerabilities for Depression and Anxiety in Childhood: Specificity of Anxiety Sensitivity and Rumination

Background: Childhood anxiety and depression frequently co-occur. Exploring specificity in cognitive processes for anxiety and depression in childhood can provide insight into cognitive vulnerabilities contributing to the development of anxiety and depressive disorders and inform targeted psychological interventions. Anxiety sensitivity and rumination are robust cognitive vulnerabilities for anxiety and depression, respectively. However, despite conceptual similarities, they are rarely considered together within a single study. Aims: The current study explored specific and shared associations between anxiety sensitivity subscales and rumination and anxiety and depressive symptoms in unselected children. Method: Multiple regression analyses explored to what extent specific self-reported anxiety sensitivity subscales (physical, social and mental concerns) and rumination predicted anxiety and depressive symptoms in 147 unselected children, aged 7–11 years. Results: Physical and social concern subscales of anxiety sensitivity were specifically associated with anxiety, whilst rumination was specifically associated with depressive symptoms. The mental concerns subscale of anxiety sensitivity was independently associated with both anxiety and depressive symptoms. These associations were only partially mediated by rumination. Conclusions: Anxiety and depression in young people are characterized by specific and shared cognitions. Evidence for shared and specific associations between the cognitive vulnerabilities of anxiety sensitivity and rumination, and anxiety and depression highlight the utility of transdiagnostic research and confirm that cognitive therapies may benefit from targeting cognitive concerns relating specifically to the patient's presenting symptoms.

A psychometric evaluation of the panic disorder severity scale for children and adolescents

The Panic Disorder Severity Scale (PDSS; Shear et al., 1997) is a well-validated measure that assesses symptoms of panic disorder with or without agoraphobia (PDA) in adults. The Panic Disorder Severity Scale for Children (PDSS-C) is an adaptation of the PDSS for youth ages 11-17. The current study evaluated the psychometric properties of the PDSS-C. Participants included 60 adolescents from a randomized controlled trial investigating the efficacy of an intensive cognitive behavioral treatment (CBT) for adolescent PDA. Convergent and discriminant validity of PDSS-C scores were evaluated via observed associations between the PDSS-C and the Childhood Anxiety Sensitivity Index (CASI; Silverman, Fleisig, Rabian, & Peterson, 1991), Multidimensional Anxiety Scale for Children (MASC; March, Parker, Sullivan, Stallings, & Conners, 1997), and Children's Depression Inventory (CDI; Kovacs, 2003). Baseline and posttreatment data afforded the opportunity to evaluate the measure's sensitivity to treatment-related change. PDSS-C scores demonstrated acceptable internal consistency (α = .82) and adequate 1-day test-retest reliability (r = .79). Convergent and discriminant validity of the PDSS-C scores were supported through significant associations with the CASI and the MASC, and nonsignificant associations with the CDI, respectively. Linear regression analysis demonstrated sensitivity to treatment-related changes-that is, greater PDSS-C change scores were significantly associated with assignment to CBT vs. waitlist condition. Clinical utility was further established through significant associations between PDSS-C change scores and MASC and CASI change scores, and through nonsignificant associations with CDI change scores. Results support the use of PDSS-C scores as reliable, valid, and clinically useful for the assessment of youth panic disorder in research and clinical settings.

Examining the latent structure of anxiety sensitivity in adolescents using factor mixture modeling

Anxiety sensitivity has been implicated as an important risk factor, generalizable to most anxiety disorders. In adults, factor mixture modeling has been used to demonstrate that anxiety sensitivity is best conceptualized as categorical between individuals. That is, whereas most adults appear to possess normative levels of anxiety sensitivity, a small subset of the population appears to possess abnormally high levels of anxiety sensitivity. Further, those in the high anxiety sensitivity group are at increased risk of having high levels of anxiety and of having an anxiety disorder. This study was designed to determine whether these findings extend to adolescents. Factor mixture modeling was used to examine the best fitting model of anxiety sensitivity in a sample of 277 adolescents (M age = 11.0 years, SD = 0.81). Consistent with research in adults, the best fitting model consisted of 2 classes, 1 containing adolescents with high levels of anxiety sensitivity (n = 25) and another containing adolescents with normative levels of anxiety sensitivity (n = 252). Examination of anxiety sensitivity subscales revealed that the social concerns subscale was not important for classification of individuals. Convergent and discriminant validity of anxiety sensitivity classes were found in that membership in the high anxiety sensitivity class was associated with higher mean levels of anxiety symptoms, controlling for depression and externalizing problems, and was not associated with higher mean levels of depression or externalizing symptoms controlling for anxiety problems.

Pediatric anxiety disorders: from neuroscience to evidence-based clinical practice

The objective of this narrative review of the literature is to describe the epidemiology, etiology, pathophysiology, diagnosis, and treatment of pediatric anxiety disorders. We aim to guide clinicians in understanding the biology of anxiety disorders and to provide general guidelines for the proper diagnoses and treatment of these conditions early in life. Anxiety disorders are prevalent, associated with a number of negative life outcomes, and currently under-recognized and under-treated. The etiology involves both genes and environmental influences modifying the neural substrate in a complex interplay. Research on pathophysiology is still in its infancy, but some brain regions, such as the amygdala and the prefrontal cortex, have been implicated in fear and anxiety. Current practice is to establish diagnosis based purely on clinical features, derived from clinical interviews with the child, parents, and teachers. Treatment is effective using medication, cognitive behavioral therapy, or a combination of both. An introduction to the neuroscience behind anxiety disorders combined with an evidence-based approach may help clinicians to understand these disorders and treat them properly in childhood.

Relationship between anxiety, anxiety sensitivity and conduct disorder symptoms in children and adolescents with attention-deficit/hyperactivity disorder (ADHD)

Attention-deficit hyperactivity disorder (ADHD) is often comorbid with anxiety disorders and previous studies observed that anxiety could have an impact on the clinical course of ADHD and comorbid disruptive behavioral disorders (conduct disorders and oppositional-defiant disorders). Anxiety sensitivity (AS) is a different concept from anxiety per se and it is believed to represent the constitutionally based sensitivity of individuals to anxiety and anxiety symptoms. We aimed to assess the associations between anxiety, AS and symptoms of disruptive behavioral disorders (DBD) in a clinical sample of children and adolescents with ADHD. The sample consisted of 274 treatment naive children with ADHD aged 8-17 years. The severity of ADHD symptoms and comorbid DBD were assessed via parent rated Turgay DSM-IV-Based Child and Adolescent Behavioral Disorders Screening and Rating Scale (T-DSM-IV-S), Conners' Parent Rating Scale (CPRS), and Conners' Teacher Rating Scale (CTRS). AS and severity of anxiety symptoms of children were evaluated by self-report inventories. The association between anxiety, AS, and DBD was evaluated using structural equation modeling. Analyses revealed that AS social subscale scores negatively predicted symptoms of conduct disorder (CD) reported in T-DSM-IV-S. On the other hand, CD symptoms positively predicted severity of anxiety. No direct relationships were detected between anxiety, AS and oppositional-defiant behavior scores in any scales. These results may suggest a protective effect of AS social area on the development of conduct disorder in the presence of a diagnosis of ADHD, while the presence of symptoms of CD may be a vulnerability factor for the development of anxiety symptoms in children and adolescents with ADHD.

Facets of the childhood anxiety sensitivity index among Serbian youth

Data from factor analytic studies using the Child Anxiety Sensitivity Index (CASI) suggest that global anxiety sensitivity (AS) is best represented by three or four underlying factors or facets. The aim of this study was to identify facets best representing the CASI structure in its Serbian version. Confirmatory factor analysis was used on data collected from 456 non-referred children in Serbia. A 13-item version of the CASI provided a better fit to the data than the original 18-item version. The four-factor model of the CASI-13 with disease, unsteady, mental incapacitation, and social concerns facets provided the best fits for the data and it was found to be fully invariant (configural, metric, and scalar invariance) across gender and age. Among Serbian children, hierarchical structure was found for a 13-item CASI version with a single higher-order factor of global AS represented by four underlying facets. Future research will consider these AS facets and their role in the development, maintenance, and exacerbation of anxiety symptoms in children.

Genetic and environmental influences on relationship between anxiety sensitivity and anxiety subscales in children

Anxiety sensitivity, a belief that symptoms of anxiety are harmful, has been proposed to influence development of panic disorder. Recent research suggests it may be a vulnerability factor for many anxiety subtypes. Moderate genetic influences have been implicated for both anxiety sensitivity and anxiety, however, little is known about the aetiology of the relationship between these traits in children. Self-reports of anxiety sensitivity and anxiety symptoms were collected from approximately 300 twin pairs at two time points. Partial correlations indicated that anxiety sensitivity at age 8 was broadly associated with most anxiety subtypes at age 10 (r=0.11-0.17, p<0.05). The associations were largely unidirectional, underpinned by stable genetic influences. Non-shared environment had unique influences on variables. Phenotypic results showed that anxiety sensitivity is a broad predictor of anxiety symptoms in childhood. Genetic results suggest that childhood is a developmental period characterised by genetic stability and time-specific environmental influences on anxiety-related traits.

Reliability and convergent validity of the Childhood Anxiety Sensitivity Index in children and adolescents

OBJECTIVE: The purpose of this study was to examine the reliability and the convergent validity of the Children Anxiety Sensitivity Index (CASI) with DSM-IV anxiety disorder symptoms, by comparison with the Screen for Child Anxiety Related Emotional Disorders (SCARED), in a community sample of Brazilian children and adolescents. METHODS: Children and adolescents from five schools were selected from a larger study that aimed to assess different aspects of childhood anxiety disorders. All participants completed the CASI and the SCARED. RESULTS: This study supported the reliability of the CASI total score. Girls reported higher total anxiety sensitivity scores than boys and there were no differences in total anxiety sensitivity scores between children and adolescents. This study showed moderate to high correlations between the CASI scores with SCARED scores, all correlations coefficients being positive and significant. CONCLUSIONS: Our findings demonstrate an appropriate reliability and evidence of convergent validity in the CASI in a sample of Brazilian children and adolescents.
