Anxiety sensitivity moderates behavioral avoidance in anxious youth

Wing-shaped walls: A directional effect of obstacles on manual avoidance

Visual information can be used to plan, start, and coordinate manual movements in obstacle avoidance. An intriguing example of visuomotor coordination is the effect of wing-shaped walls, in which walls are oriented away from or toward a moving agent. A historical story from medieval Japan recounts that wing-shaped walls disrupted the agent's movement more when oriented toward the agent than when oriented away from the agent. This study aimed at examining whether the disruptive effect of wing-shaped walls occurs in a schematic situation represented on a 2D plane. In this study, we conducted psychophysical experiments in which participants were asked to move a stylus from a start point to a goal while avoiding multiple line obstacles that were arranged alternately at a course. In the two experiments, we manipulated the orientation and the size of the visible parts of the obstacles systematically. We found that the obstacles oriented toward the agent produced frequent contacts with the agent and attracted manual movements to the endpoints of obstacles. We discussed possible interpretations of the results in the context of attentional guidance.

Responding to threat: Associations between neural reactivity to and behavioral avoidance of threat in pediatric anxiety

BACKGROUND

Despite broad recognition of the central role of avoidance in anxiety, a lack of specificity in its operationalization has hindered progress in understanding this clinically significant construct. The current study uses a multimodal approach to investigate how specific measures of avoidance relate to neural reactivity to threat in youth with anxiety disorders.

METHODS

Children with anxiety disorders (ages 6-12 years; n = 65 for primary analyses) completed laboratory task- and clinician-based measures of avoidance, as well as a functional magnetic resonance imaging task probing neural reactivity to threat. Primary analyses examined the ventral anterior insula (vAI), amygdala, and ventromedial prefrontal cortex (vmPFC).

RESULTS

Significant but distinct patterns of association with task- versus clinician-based measures of avoidance emerged. Clinician-rated avoidance was negatively associated with right and left vAI reactivity to threat, whereas laboratory-based avoidance was positively associated with right vAI reactivity to threat. Moreover, left vAI-right amygdala and bilateral vmPFC-right amygdala functional connectivity were negatively associated with clinician-rated avoidance but not laboratory-based avoidance.

LIMITATIONS

These results should be considered in the context of the restricted range of our treatment-seeking sample, which limits the ability to draw conclusions about these associations across children with a broader range of symptomatology. In addition, the limited racial and ethnic diversity of our sample may limit the generalizability of findings.

CONCLUSION

These findings mark an important step towards bridging neural findings and behavioral patterns using a multimodal approach. Advancing understanding of behavioral avoidance in pediatric anxiety may guide future treatment optimization by identifying individual-specific targets for treatment.

Anxiety sensitivity and experiential avoidance: Relations with anxiety severity and treatment outcomes in anxious youth

Purpose

Anxiety sensitivity (AS) and experiential avoidance (EA) are associated with anxiety in both adults and youths. This study examined the separate contributions of AS and EA in predicting (a) anxiety (symptom severity) and (b) differential treatment outcomes in anxious youth receiving cognitive behavioral therapy (CBT).

Methods

Participants (N = 89; age 10-17 years; 37% male; 78% white) met diagnostic criteria for an anxiety disorder and received CBT (Coping Cat). AS and EA were child-report measures collected at baseline. The outcome variables were anxiety symptom severity (Multidimensional Anxiety Scale for Children; child- and parent-reported) and Independent Evaluator-rated anxiety severity (Child Global Impression-Severity) collected at baseline and posttreatment. Multilevel models (MLM) examined independent and relative contributions of AS and EA to the outcome variables as a secondary analysis.

Results

Both AS and EA were associated with levels of anxiety symptom severity at pretreatment and at posttreatment, varying by reporter. Neither AS nor EA predicted differential treatment outcomes: youth at varying levels had comparably favorable outcomes.

Conclusions

Findings suggest similarity in AS and EA, and that both constructs may be adequately and equally addressed in CBT. Future research could consider examining change in AS and EA and anxiety across treatment in diverse populations.

Reduction in avoidance mediates effects of brief behavioral therapy for pediatric anxiety and depression

Brief behavioral therapy (BBT) is an efficacious transdiagnostic intervention for pediatric anxiety and depression that targets behavioral avoidance as a key mechanism. It is unknown if change in avoidance mediates treatment effects, as theorized. Data on avoidance at baseline and Week 16 were available on 52 youth (ages 8-16 years) from a randomized controlled trial (Weersing, Jeffreys, et al., 2017) comparing BBT and assisted referral to community care (ARC). BBT had significant effects on youth-reported behavioral avoidance, and significant indirect effects on functioning and anxiety, statistically mediated through changes in youth-reported behavioral avoidance. Change in youth-reported avoidance was not a significant mediator of depression. Parent-report of avoidance was not impacted by treatment and was not a significant mediator. Overall, BBT appears to be an effective treatment for targeting behavioral avoidance, which in turn, may improve functioning and lessen anxiety.

Family accommodation in pediatric anxiety: Relations with avoidance and self-efficacy

Pediatric anxiety disorders are common, impairing, and chronic when not effectively treated. A growing body of research implicates family accommodation in the maintenance of pediatric anxiety. The present study aimed to quantify previously untested relations among family accommodation and two theoretically linked constructs: avoidance and self-efficacy. Eighty youths between ages 8 and 17 (53 with anxiety disorders, 27 non-anxious controls) completed measures of family accommodation and self-efficacy. In addition, avoidance was assessed using two distinct measures of avoidance: a clinician rating of real-world behaviors and a laboratory task-based index. As predicted, youths with anxiety disorders reported greater family accommodation than non-anxious controls. Across the sample, greater family accommodation was associated with greater avoidance, as measured using both clinician rating and the laboratory task, as well as with lower self-efficacy. In an exploratory mediation model, self-efficacy partially mediated the relation between family accommodation and clinician-rated avoidance; however, it did not mediate the relation between family accommodation and task-based avoidance. Considering the robust association between family accommodation and anxiety in youths, this addition to our understanding of related cognitive and behavioral factors provides important preliminary insight, which can guide future research on potential targets for early identification and intervention for pediatric anxiety.

Conditioned physiological reactivity and PTSD symptoms across the menstrual cycle: Anxiety sensitivity as a moderator

OBJECTIVE

Posttraumatic stress disorder (PTSD) is often associated with heightened physiological reactivity during fear conditioning procedures, but results vary across studies. This study examined whether anxiety sensitivity (AS), or the fear of arousal-related sensations, strengthens the relationship between PTSD symptoms and skin conductance responses (SCR) during fear conditioning and extinction. Because gonadal hormones implicated in fear learning fluctuate across the menstrual cycle, the stability of these relationships in women was examined in 2 distinct menstrual cycle phases.

METHOD

Thirty-two trauma-exposed women, half of whom had PTSD, completed the Clinician-Administered PTSD Scale, Anxiety Sensitivity Inventory, and a fear conditioning and extinction paradigm during the midluteal (mLP) and early-follicular (eFP) menstrual cycle phases.

RESULTS

In the mLP, stronger SCR to stimuli paired with shock (CS +) during fear acquisition significantly predicted greater PTSD symptoms only when AS was high and after removing an outlier. This appeared driven by effects on Numbing and Hyperarousal symptom clusters. Other hypothesized interactions between AS and CS responses were not significant. However, in the eFP, differential SCR between the CS + and CS- during extinction predicted significantly greater PTSD symptoms, and there was a trend for this effect being stronger as AS increased.

CONCLUSIONS

Results offer preliminary evidence that high AS contributes to a stronger relationship between SCR during fear acquisition and PTSD symptoms, at least among women in the mLP. Further research investigating the impact of individual differences in traits such as AS on the relationship between conditioned fear responses and PTSD symptoms is warranted.

Using Evaluative Criteria to Review Youth Anxiety Measures, Part I: Self-Report

Evidence-based assessment serves several critical functions in clinical child psychological science, including being a foundation for evidence-based treatment delivery. In this Evidence Base Update, we provide an evaluative review of the most widely used youth self-report measures assessing anxiety and its disorders. Guided by a set of evaluative criteria (De Los Reyes & Langer, 2018), we rate the measures as Excellent, Good, or Adequate across their psychometric properties (e.g., construct validity). For the eight measures evaluated, most ratings assigned were Good followed by Excellent, and the minority of ratings were Adequate. We view these results overall as positive and encouraging, as they show that these youth anxiety self-report measures can be used with relatively high confidence to accomplish key assessment functions. Recommendations and future directions for further advancements to the evidence base are discussed.

Converging Multi-modal Evidence for Implicit Threat-Related Bias in Pediatric Anxiety Disorders

This report examines the relationship between pediatric anxiety disorders and implicit bias evoked by threats. To do so, the report uses two tasks that assess implicit bias to negative-valence faces, the first by eye-gaze and the second by measuring body-movement parameters. The report contrasts task performance in 51 treatment-seeking, medication-free pediatric patients with anxiety disorders and 36 healthy peers. Among these youth, 53 completed an eye-gaze task, 74 completed a body-movement task, and 40 completed both tasks. On the eye-gaze task, patients displayed longer gaze duration on negative relative to non-negative valence faces than healthy peers, F(1, 174) = 8.27, p = .005. In contrast, on the body-movement task, patients displayed a greater tendency to behaviorally avoid negative-valence faces than healthy peers, F(1, 72) = 4.68, p = .033. Finally, implicit bias measures on the two tasks were correlated, r(38) = .31, p = .049. In sum, we found an association between pediatric anxiety disorders and implicit threat bias on two tasks, one measuring eye-gaze and the other measuring whole-body movements. Converging evidence for implicit threat bias encourages future research using multiple tasks in anxiety.

Anxiety sensitivity and bodily kinematics

Anxiety sensitivity (AS) is an individual difference factor reflecting the fear of anxiety-related sensations and is one of the best researched risk factors for psychopathology. Decades of research have focused on exploring the relations between AS and clinical symptoms and disorders, although most of the research has employed self-report or interview-based methodologies to index primary dependent measures. No past research has sought to characterize the explanatory relevance of AS from a body kinematics perspective. The present study explored AS in relation to body kinematics to AS-specific images using a dual-task attentional control paradigm (i.e., approach versus avoidance) that employs AS-specific stimuli and motion-tracking technology. Participants included 108 young adults (58.3% female, M age = 25.3) who took part in a ball catching game to index their measures of behavioral engagement with the AS-specific and neutral stimuli presented at either side of the game environment. After adjusting for age, gender, race, handedness, physical functioning, and negative affectivity, self-reported AS was significantly associated with biokinematically-driven behavioral engagement with the AS-specific stimuli. The present study provides novel empirical evidence that AS is related to anxiety-related bodily kinematics. Future work is needed to extend the current results to clinical samples.

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.

Type D personality, anxiety sensitivity, social anxiety, and disability in patients with acne: a cross-sectional controlled study

Introduction

Acne has long been associated with many psychiatric comorbidities.

Aim

To determine anxiety and depression levels, social phobia frequency, social anxiety level, subjective stress perception, anxiety sensitivity, disability, and the frequency of type D personality in patients with acne.

Material and methods

In total, 61 patients with acne aged > 16 years and 61 age, gender, and educationally matched healthy volunteers were included in the study. The patients and healthy controls were evaluated using the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria for social anxiety disorder and completed the Liebowitz Social Anxiety Scale, Sheehan Disability Scale, Anxiety Sensitivity Index, Hospital Anxiety and Depression Scale, Perceived Stress Scale (PSS), and Type D Scale-14.

Results

Depression, anxiety, social anxiety, self-reported stress, anxiety sensitivity, and disability levels were significantly higher in patients with acne than in healthy controls (p < 0.05). Type D personality was more prevalent in patients with acne than in healthy controls (49% vs. 18%, p < 0.001).

Conclusions

To our knowledge, this study is the first reported in which type D personality and anxiety sensitivity, as well as social anxiety disorder according to the DSM-5 criteria, was evaluated in patients with acne compared with healthy controls. This study shows that patients with acne have higher levels of depression, anxiety, social anxiety, self-reported stress, anxiety sensitivity, and disability, and a greater prevalence of type D personality, than healthy controls. Psychiatric evaluation of patients with acne may aid the detection of mental disorders.

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.

Using Motion Tracking to Measure Avoidance in Children and Adults: Psychometric Properties, Associations With Clinical Characteristics, and Treatment-Related Change

Avoidance is implicated in many areas of psychopathology, particularly anxiety and its disorders. Accurate, reliable, valid, and objective measurement of avoidance behavior poses methodological challenges. Two key technological advances, increased computing power and the advent of motion-tracking technology, offer novel solutions to these challenges. We describe a series of three studies using a novel motion-tracking system to measure avoidance in children and adults. The first study examined behavioral avoidance of spider stimuli in large samples of children and adults (N = 200 each; the adults were the mothers of the children). Behavioral avoidance was associated with self-rated fear of spiders and increased state anxiety from before to after the task. The second study examined avoidance of threat faces in children and adults (N = 35 each; the adults were the mothers of the children) and test-retest reliability in the adults. Avoidance of threat faces was associated with broadband anxiety symptom severity. Test-retest correlations in behavioral avoidance measured 6 weeks apart was high and significant. The third study examined behavioral avoidance of spiders in clinically anxious children (N = 25) before and after cognitive-behavioral therapy for childhood anxiety disorders. Behavioral avoidance was significantly reduced following cognitive-behavioral therapy and reduction in behavioral avoidance correlated significantly with improvement in child-rated anxiety symptoms. Taken together, these studies provide strong support for the promise of motion-tracking technology to enable a new phase of behavioral avoidance research with sensitive, valid, reliable, and cost- and time-effective measurement of behavioral avoidance across the lifespan.

Maternal Acceptance Moderates Fear Ratings and Avoidance Behavior in Children

Avoidance is a hallmark feature of anxiety disorders, and avoidance-related impairment is often key to meeting diagnostic criteria. In children and adolescents with anxiety disorders, levels of avoidance vary considerably. Using a novel motion-tracking measure of avoidance behavior, we examined whether maternal acceptance, characterized by warm and accepting responses to child feelings and behaviors, moderates the association between fear of spiders and behavioral avoidance of spider stimuli in 103 clinically anxious children. As hypothesized, maternal acceptance significantly moderated children's avoidance behavior. Child's fear of spiders was significantly associated with behavioral avoidance when mothers were low in acceptance, as rated by either mothers or children. When mothers were high in acceptance, as rated by either mothers or children, child self-rated fear of spiders was not significantly associated with child avoidance. These are the first results to empirically demonstrate the moderating role of maternal acceptance in anxious children's avoidance behavior.

Anxiety Sensitivity Moderates the Relation Between Family Accommodation and Anxiety Symptom Severity in Clinically Anxious Children

High levels of family accommodation (FA), or parental involvement in child symptoms, are associated with child anxiety symptom severity. The strength of associations has varied across studies, however, highlighting the need to identify moderating variables. We investigated whether anxiety sensitivity (AS) moderated the FA-anxiety symptom severity association in clinically anxious children (N = 103, ages 6-17; mean age 11.07 years). We collected child and mother ratings of FA, child anxiety symptom severity, and child AS ratings. AS significantly moderated the FA-child anxiety severity link. Specifically, this link was significant for low-AS but not high-AS children. Findings suggest that FA may operate in the typically observed fashion for low-AS children-alleviating immediate distress while inadvertently exacerbating longer-term anxiety-whereas high-AS children may experience distress following anxiety-provoking stimuli regardless of FA. Assessing AS in research and clinical settings may help identify subsets of children for whom FA is more closely tied to anxiety severity.

Implications of the Research Domain Criteria project for childhood anxiety and its disorders

Anxiety disorders are among the most prevalent psychiatric disorders in youth; however, progress in treatment for childhood anxiety has stalled over the past decade. The National Institute of Mental Health (NIMH) Research Domain Criteria (RDoC) project represents a shift toward a dimensional and interdisciplinary approach to psychiatric disorders; this shift can reframe developmental psychopathology for childhood anxiety and facilitate novel advances in its classification and treatment. Here we highlight constructs in the Systems for Social Processes and the Negative Valence System domains of RDoC, as they relate to childhood anxiety disorders. Childhood anxiety relates to both RDoC domains. In terms of social processes, through natural reliance on parents to reduce children's fear, attachment represents one particular social process, which plays a central role in anxiety among youth. In terms of negative valence, considerable research links threat conditioning to pediatric anxiety. Finally, fronto-amygdala circuitry relates to all three entities, as it has been shown to underly both attachment processes and threat learning, while it also has been consistently implicated in anxiety disorders across development. Through integrative and translational approaches, RDoC provides unique opportunities and simultaneous challenges for advancing the understanding and treatment of childhood anxiety disorders.

Anxiety and Atopic Disease: Comorbidity in a Youth Mental Health Setting

Anxiety frequently co-occurs with atopic diseases (e.g., allergies) in community samples, although data are limited to community and pediatric medical samples. Little work has examined atopy rates among mental health treatment seeking youth or whether youth with comorbid anxiety and atopy present similarly to non-comorbid youth. Using initial intake data from a University-based specialty youth clinic for anxiety and depressive disorders (n = 189), rates of atopic comorbidity were benchmarked against lifetime prevalence estimates in epidemiological samples. Anxiety severity and parental stress were compared between youth with and without atopy. Results indicated high rates of atopy in the clinical sample (51.3 %) relative to population atopy estimates (34.5 %). Anxious youth with atopy exhibited more overall and generalized anxiety symptoms relative to non-atopic youth (ps < .05); parental stress was comparable between atopic and non-atopic anxious youth. This suggests potentially heightened clinical severity for youth with co-occurring anxiety and atopy.

Mother and Child Ratings of Child Anxiety: Associations With Behavioral Avoidance and the Role of Family Accommodation

OBJECTIVE

This study compared mother and child ratings of child anxiety to each other and to an objective measure of the child's avoidant behavior, using a novel motion-tracking paradigm. The study also examined the moderating role of family accommodation for the link between mother ratings of child anxiety and child behavioral avoidance.

DESIGN

Participants were 98 children (7- to 14-years-old) and their mothers. Children met criteria for a primary anxiety disorder. Measures included parent and child versions of the Multi-Dimensional Anxiety Scale for Children and the Screen for Child Anxiety Related Emotional Disorders. Children also completed the Spider Phobia Questionnaire for children and the Family Accommodation Scale for Anxiety-Child Report. The Yale Interactive Kinect Environment Software platform was used to measure children's behavioral avoidance of spider images.

RESULTS

Mother and child ratings of child anxiety were moderately correlated. Only child ratings of child anxiety were associated with child behavioral avoidance. Child-rated family accommodation moderated the association between parent ratings and child avoidance. When accommodation was low parent ratings correlated with child avoidance, but not when accommodation was high.

CONCLUSIONS

The findings contribute to understanding commonly reported discrepancies between mother and child ratings of child anxiety symptoms.

Is disgust proneness sensitive to treatment for OCD among youth?: Examination of diagnostic specificity and symptom correlates

Although disgust proneness has been implicated in obsessive-compulsive disorder (OCD), there is a paucity of research examining change in disgust proneness during treatment as well as the correlates of such change, especially in children. This study examined the relationship between changes in disgust proneness and disorder-specific symptoms during residential treatment among youth with OCD, anxiety, and mood disorders. Youth ages 12-18 (n=472) completed pre- and post-outcome measures of OCD, anxiety, and mood symptoms and disgust proneness. Results indicate that although disgust proneness decreases during treatment for youth with OCD, anxiety, and mood disorders, youth with primary OCD experienced the greatest decrease in disgust proneness over the course of treatment. Reductions in disgust proneness during treatment were significantly correlated with reductions in multiple symptom measures, with the strongest correlations between reductions in disgust proneness and OCD symptoms. Implications and directions for future research are discussed.
