A pilot RCT of a school nurse delivered intervention to reduce student anxiety

The goal of this study was to evaluate the feasibility and impact of brief school-nurse-administered interventions for reducing anxiety. Thirty school nurses in Connecticut and Maryland were randomly assigned to deliver the Child Anxiety Learning Modules (CALM; n = 14) or CALM-Relaxation only (CALM-R; n = 16). Students (N = 54) were ages 5-12 (M age = 8; 84.9% White; 68.5% female) with elevated anxiety symptoms and/or anxiety disorders. Feasibility was assessed based on recruitment, retention, attendance, training and intervention satisfaction, and intervention adherence. Multiple informants, including independent evaluators (IEs), completed measures of clinical improvement at postintervention and at a 3-month follow-up. Of nurses in CALM and CALM-R, 62% and 81%, respectively, enrolled a student and completed an average of 6 sessions. Youth retention was 85% and 94% in CALM and CALM-R, respectively. Training and intervention satisfaction were high. At postintervention and follow-up, youth in both groups showed significant reductions in anxiety and related symptoms and improvements in functioning. Within-group effect sizes were medium to large, and between-group effect sizes were small. Task shifting responsibility for delivering brief mental health interventions to school nurses is feasible and shows promise for reducing anxiety and related impairment. This approach may also be integrated within a response to intervention model used in schools.Public Health Significance: Brief school-nurse-administered anxiety reduction interventions were shown to be feasible and had a positive impact on student anxiety and related impairment highlighting that school nurses can be an important school resource.

Person-Centered Profiles Among Treatment-Seeking Children and Adolescents with Anxiety Disorders

Latent profile analysis (LPA) was used to derive homogeneous subgroups within the Child/Adolescent Anxiety Multimodal Study sample (N = 488; 7-17 years, M = 10.69, SD = 2.80) and examine whether class membership predicted or moderated treatment response. Subgroups were identified on baseline multi-informant measures of variables most consistently associated with outcome (youth anxiety/diagnosis, impairment, family psychopathology/functioning). Subgroup membership was examined as a predictor/moderator of outcome across the four treatment conditions (CBT, Sertraline, CBT+Sertraline, pill placebo) at posttreatment (12 weeks) and open-extension follow-up (24 weeks). Four subgroups emerged: mild symptoms/impairment, moderate symptoms/impairment, moderate symptoms/impairment with family dysfunction/parental psychopathology, and severe symptoms/impairment. There were significant between-class differences on socioeconomic status (SES; lower reported SES in the moderate with family dysfunction/parental psychopathology class compared to the mild and moderate class) and age (older age in the severe symptoms class compared to the other three classes). Youth in the mild symptoms/impairment class showed lower posttreatment anxiety across conditions but reported significantly lower symptom severity at baseline. Controlling for demographic differences, response to treatment type did not differ across classes. Analyses indicate that elevated family dysfunction/parental psychopathology clusters primarily within one subgroup of anxious youth rather than mapping onto symptom severity, highlighting the utility of LPA for clarifying within-person combinations of predictor/moderator variables. Implications for development of interventions targeting class-relevant variables are discussed.

Pharmacotherapy Adherence for Pediatric Anxiety Disorders: Predictors and Relation to Child Outcomes

Background

Pharmacotherapy is considered an evidenced-based treatment for anxious youth. There is a need to better understand the relation between medication adherence and child outcomes.

Objective

This study prospectively examined:1) baseline predictors of adherence and 2) the relation between medication adherence and clinical outcomes in children and adolescents with anxiety disorders.

Methods

Participants were 349 youth randomized to sertraline, pill placebo, or sertraline plus cognitive behavioral therapy in the Child/Adolescent Anxiety Multimodal Study (CAMS) and followed over 12 weeks. The measure of pharmacotherapy adherence used was pharmacotherapist (PT) ratings of adherence at each session. Four domains of baseline predictors were examined (demographics, child clinical variables, family/parent variables, and treatment variables).

Results

Multiple regression analyses revealed few significant predictors of adherence. The most robust predictors of greater adherence were living with two parents and parents' positive expectations that medication would lead to better outcomes. Pharmacotherapists' ratings of higher adherence predicted higher global functioning at post treatment and treatment responder status.

Conclusions

In order to increase adherence, improving expectations and instilling hope for positive outcomes and problem solving ways to overcome pragmatic barriers associated with single parent families is recommended.

Community Study of Outcome Monitoring for Emotional Disorders in Teens (COMET): A comparative effectiveness trial of a transdiagnostic treatment and a measurement feedback system

Emotional disorders, encompassing a range of anxiety and depressive disorders, are the most prevalent and comorbid psychiatric disorders in adolescence. Unfortunately, evidence-based psychosocial therapies typically focus on single disorders, are rarely adopted by community mental health center clinicians, and effect sizes are modest. This article describes the protocol for a comparative effectiveness study of two novel interventions designed to address these challenges. The first intervention is a transdiagnostic treatment (the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents, UP-A), a promising new approach that uses a small number of common strategies to treat a broad range of emotional disorders, and their underlying shared emotional vulnerabilities. The second intervention is a standardized measurement feedback system, the Youth Outcomes Questionnaire (YOQ), designed to improve clinical decision making using weekly symptom and relational data. The three study arms are treatment as usual (TAU), TAU plus the YOQ (TAU+), and UP-A (used in combination with the YOQ). The primary aims of the study are to [1] compare the effects of the UP-A and TAU+ to TAU in community mental health clinics, [2] to isolate the effects of measurement and feedback by comparing the UP-A and TAU+ condition, and [3] to examine the mechanisms of action of both interventions. Design considerations and study methods are provided to inform future effectiveness research.

Results From the Child/Adolescent Anxiety Multimodal Extended Long-Term Study (CAMELS): Primary Anxiety Outcomes

OBJECTIVE

To report anxiety outcomes from the multisite Child/Adolescent Anxiety Multimodal Extended Long-term Study (CAMELS). Rates of stable anxiety remission (defined rigorously as the absence of all DSM-IV TR anxiety disorders across all follow-up years) and predictors of anxiety remission across a 4-year period, beginning 4 to 12 years after randomization to 12 weeks of medication, cognitive-behavioral therapy (CBT), their combination, or pill placebo were examined. Examined predictors of remission included acute treatment response, treatment assignment, baseline child and family variables, and interim negative life events.

METHOD

Data were from 319 youths (age range 10.9-25.2 years; mean age 17.12 years) originally diagnosed with separation, social, and/or generalized anxiety disorders and enrolled in the multi-site Child/Adolescent Anxiety Multimodal Study (CAMS). Participants were assessed annually by independent evaluators using the age-appropriate version of the Anxiety Disorders Interview Schedule and completed questionnaires (eg, about family functioning, life events, and mental health service use).

RESULTS

Almost 22% of youth were in stable remission, 30% were chronically ill, and 48% were relapsers. Acute treatment responders were less likely to be in the chronically ill group (odds ratio = 2.73; confidence interval = 1.14-6.54; p < .02); treatment type was not associated with remission status across the follow-up. Several variables (eg, male gender) predicted stable remission from anxiety disorders.

CONCLUSION

Findings suggest that acute positive response to anxiety treatment may reduce risk for chronic anxiety disability; identified predictors can help tailor treatments to youth at greatest risk for chronic illness.

The Interplay of Familial and Individual Risk in Predicting Clinical Improvements in Pediatric Anxiety Disorders

Bioecological models of developmental psychopathology underscore the role of familial experiences of adversity and children's individual-level characteristics in heightening risk for pediatric anxiety through direct, combined, and interactive effects. To date, much of the existing research dedicated to pediatric anxiety disorders has largely been examined in bioecological models of diathesis-stress using community samples. This study extends our understanding of children's differential responsiveness to familial adversity by examining the diathesis-stress interaction of cumulative risk and children's individual-level vulnerabilities (negative affectivity and coping efficacy) within a clinic-referred treatment study for pediatric anxiety disorders. A cumulative risk index assessing exposure to familial adversity (e.g., socioeconomic status [SES], parent psychiatric illness) and self-reported measures of children's negative affectivity and coping efficacy were each measured at the intake of a randomized controlled clinical trial for the treatment of pediatric anxiety disorders (N = 488; 7-17 years of age). Trajectories of interviewer-rated anxiety symptoms were assessed across 12 weeks of treatment at baseline, 4 weeks, 8 weeks, and 12 weeks. Consistent with models of temperamental risk for mental health problems, negative affectivity predicted higher anxiety symptoms at intake. A significant diathesis-stress interaction between cumulative risk and coping efficacy emerged, as high risk and perceptions of lower coping efficacy attenuated declines in anxiety across 12 weeks. These patterns did not differ across treatment conditions. The results indicate that for youth experiencing high levels of stress, additional treatment efforts targeting familial stressors and coping efficacy may be important in maximizing treatment outcomes.

Family and Parent Predictors of Anxiety Disorder Onset in Offspring of Anxious Parents

BACKGROUND

Offspring of anxious parents are at increased risk for developing anxiety disorders. There is a need to identify which youth are at greatest risk for disorder onset in this population.

OBJECTIVE

This study prospectively examined several theory-based family and parent characteristics (e. g., family conflict, parental over-control, parental psychopathology) as predictors of anxiety disorder onset in children whose parents were clinically anxious.

METHODS

Families were enrolled in a randomized controlled trial evaluating a familybased preventative intervention, relative to an information monitoring control condition, for offspring of anxious parents (N= 136; child mean age 8.69 years; 55% female; 85% Caucasian). Family and parent measures were collected using multiple informants and an observational task at baseline, post-intervention, and at a six and 12 month followup. Child anxiety disorder diagnosis was determined by independent evaluators using the Anxiety Disorders Interview Schedule for Children.

RESULTS

Results indicated that none of the baseline family or parent variables examined predicted the onset of an anxiety disorder in children over the one year follow-up period.

CONCLUSIONS

Findings raise questions about the short-term risk associated with family and parent factors in anxiety disorder development in this high risk population.

Defining Treatment Response and Remission in Youth Anxiety: A Signal Detection Analysis With the Multidimensional Anxiety Scale for Children

OBJECTIVE

To determine the percent reduction cutoffs on the Multidimensional Anxiety Scale for Children (MASC) that optimally predict treatment response and remission in youth with anxiety disorders.

METHOD

Youths and their parents completed the MASC-C/P before and after treatment, and the Anxiety Disorders Interview Schedule for DSM-IV-Child and Parent Versions (ADIS-IV-C/P) and the Clinical Global Impression-Improvement Scale (CGI-I) were administered by independent evaluators. Treatment response and remission were defined by post-treatment ratings on the CGI-I and the ADIS-IV-C/P, respectively. Quality receiver operating characteristic methods determined the optimal cutoff on the MASC-P for predicting overall remission (loss of all study entry diagnoses) and optimal percent reductions on the MASC-P for predicting treatment response and remission of separation anxiety, social anxiety, and generalized anxiety.

RESULTS

A post-treatment raw score of 42 optimally predicted remission. A reduction of 35% on the total MASC-P predicted treatment response. A reduction of 30% on the Separation Anxiety/Panic subscale of the MASC-P predicted separation anxiety remission. A reduction of 35% on the Social Anxiety subscale of the MASC-P predicted social anxiety remission. The MASC did not evidence a cutoff for remission of generalized anxiety disorder.

CONCLUSION

MASC cutoffs can facilitate comparison across studies and guide practice, aiding clinicians in assessing progress and informing treatment plans.

Long-Term Outcomes of Youth Treated for an Anxiety Disorder: A Critical Review

Pediatric anxiety disorders are common, disabling, and chronic conditions. Efforts over the past two decades have focused on developing and testing effective treatments. Short-term efficacy of both Cognitive Behavioral Therapy (CBT) and selective serotonin reuptake inhibitors has been established. Data are emerging on the long-term (i.e., 2 years or longer) effectiveness of these treatments, but this literature has yet to be adequately synthesized. This study presents a systematic and critical qualitative review of published long-term follow-up (LTFU) studies of youth treated for an anxiety disorder. A comprehensive search of several databases identified 21 published reports (representing 15 LTFU cohorts of treated youth) meeting specified inclusion criteria. LTFU assessments occurred a mean of 5.85 years after initial treatment (range 2-19 years). Diagnostic rates at LTFU and predictors (e.g., demographic, baseline child clinical variables, treatment type) of outcomes at LTFU were also examined. A discussion of the limitations of this literature is provided to qualify interpretations of findings and to inform future studies. Findings can aid clinicians and families in making treatment decisions and setting reasonable expectations for the long-term prognosis after treatment for anxiety.

School Nurse Perceptions of Student Anxiety

Anxiety disorders are common in youth. Because somatic complaints are a hallmark feature of anxiety, these students frequently visit their school nurse, creating an ideal opportunity for nurses to identify and assist them. In an effort to better understand current practices, we surveyed a large sample ( N = 93) of school nurses. Results indicated that the majority of nurses perceived anxiety as the most prevalent mental health issue in their students. Moreover, the majority of nurses reported that they did not use any formal screening tool or intervention protocol and stated wanting to expand their training in anxiety intervention. These data suggest that school nurses identify anxiety as a top problem but do not receive adequate training to address it. Data from this survey may be used to plan how best to fill gaps in nurse training and practices that can enhance nurses' capacity to optimize outcomes for anxious students.

Parent-youth informant disagreement: Implications for youth anxiety treatment

Greater parent-youth disagreement on youth symptomatology is associated with a host of factors (e.g., parental psychopathology, family functioning) that might impede treatment. Parent-youth disagreement may represent an indicator of treatment prognosis. Using data from the Child/Adolescent Anxiety Multimodal Study, this study used polynomial regression and longitudinal growth modeling to examine whether parent-youth agreement prior to and throughout treatment predicted treatment outcomes (anxiety severity, youth functioning, responder status, and diagnostic remission, rated by an independent evaluator). When parents reported more symptoms than youth prior to treatment, youth were less likely to be diagnosis-free post-treatment; this was only true if the youth received cognitive-behavioral therapy (CBT) alone, not if youth received medication, combination, or placebo treatment. Increasing concordance between parents and youth over the course of treatment was associated with better treatment outcomes across all outcome measures ( ps < .001). How parents and youth "co-report" appears to be an indicator of CBT outcome. Clinical implications and future directions are discussed.

Mediators of Treatment Outcomes for Anxious Children and Adolescents: The Role of Somatic Symptoms

Cognitive behavioral therapy (CBT) and selective serotonin reuptake inhibitors are effective treatments for pediatric anxiety disorders. However, the mechanisms of these treatments are unknown. Previous research indicated that somatic symptoms are reduced following treatment, but it is unclear if their reductions are merely a consequence of treatment gains. This study examined reductions in somatic symptoms as a potential mediator of the relationship between treatment and anxiety outcomes. Participants were 488 anxious youth ages 7-17 (M = 10.7), 50.4% male, 78.9% Caucasian, enrolled in Child/Adolescent Anxiety Multimodal Study, a large randomized control trial comparing 12-week treatments of CBT, sertraline, a combination of CBT and sertraline, and a pill placebo. Causal mediation models were tested in R using data from baseline, 8-, and 12-week evaluations. Somatic symptoms were assessed using the Panic/Somatic subscale from the Screen for Child Anxiety Related Emotional Disorders. Youth outcomes were assessed using the Pediatric Anxiety Rating Scale and Children's Global Assessment Scale. Reductions in somatic symptoms mediated improvement in anxiety symptoms and global functioning for those in the sertraline-only condition based on parent report. Conditions involving CBT and data based on child reported somatic symptoms did not show a mediation effect. Findings indicate that reductions in somatic symptoms may be a mediator of improvements for treatments including pharmacotherapy and not CBT. Although the overall efficacy of sertraline and CBT for anxiety may be similar, the treatments appear to function via different mechanisms.

Secondary Outcomes From the Child/Adolescent Anxiety Multimodal Study: Implications for Clinical Practice

BACKGROUND

Controlled evaluations comparing medication, cognitive-behavioral therapy (CBT), and their combination in the treatment of youth anxiety have predominantly focused on global ratings by independent evaluators. Such ratings are resource-intensive, may be of limited generalizability, and do not directly inform our understanding of treatment responses from the perspective of treated families. We examined outcomes from the perspective of treated youth and parents in the Child/Adolescent Anxiety Multimodal Study (CAMS).

METHODS

Participants (N=488; ages 7-17 years) who had a primary diagnosis of separation, social, and/or generalized anxiety disorder were randomly assigned to a treatment condition in the CAMS trial. Linear mixed-effects and ANCOVA models examined parent- and youth-reported anxiety symptoms, impact of anxiety, broader internalizing and externalizing psychopathology, depressive symptoms, and family burden throughout the 12-week acute treatment phase and 6-month follow-up.

RESULTS

At week 12, combination treatment showed superiority over placebo, sertraline, and CBT with regard to parent-reported youth anxiety symptoms, and sertraline and CBT as monotherapies showed superiority over placebo with regard to parent-reported youth anxiety. Combination therapy and sertraline also showed week 12 superiority over placebo with regard to parent-reported internalizing psychopathology, and superiority over placebo and CBT with regard to parent-reported impact of anxiety, family burden, and youth depressive symptoms. By week 36, parent reports of many youth outcomes were comparable across active conditions. Youth measures tracked parent measures on many outcomes.

CONCLUSIONS

Findings were drawn on brief, readily available questionnaires that in conjunction with clinician measures can inform patient-centered care and collaborative decision-making.Trial Registry Name: Child and Adolescent Anxiety Disorders (CAMS)Registry identification number: NCT00052078Registry URL: https://www.clinicaltrials.gov/ct2/show/NCT00052078.

Therapist-Reported Features of Exposure Tasks That Predict Differential Treatment Outcomes for Youth With Anxiety

OBJECTIVE

Exposure tasks are recognized widely as a key component of cognitive-behavioral therapy (CBT) for child and adolescent anxiety. However, little research has examined specific exposure characteristics that predict outcomes for youth with anxiety and that may guide its application in therapy.

METHOD

This study draws on a sample of 279 children and adolescents (48.4% male; 79.6% white) with a principal anxiety disorder who received 14 sessions of CBT, either alone or in combination with medication, through the Child/adolescent Anxiety Multimodal treatment Study (CAMS). The present study examines therapist-reported quantity, difficulty level, compliance, and mastery of exposure tasks as they related to CBT response (i.e., Clinical Global Impressions-Improvement ratings). Secondary treatment outcomes included reduction in anxiety symptom severity on the Pediatric Anxiety Rating Scale, global impairment measured via the Children's Global Assessment Scale, and parent-report of anxiety-specific functional impairment on the Child Anxiety Impairment Scale.

RESULTS

Regression analyses indicated a dose-response relationship between therapist-reported quantity of exposure and independent evaluations of treatment outcome, with more time devoted to exposure linked to better outcomes. Similarly, greater time spent on more difficult (rather than mild or moderate) exposure tasks predicted better outcomes, as did therapist ratings of child compliance and mastery.

CONCLUSION

The present findings highlight the importance of challenging children and adolescents with difficult exposure tasks and of collaborating to ensure compliance and mastery.

Establishing Clinical Cutoffs for Response and Remission on the Screen for Child Anxiety Related Emotional Disorders (SCARED)

OBJECTIVE

To determine optimal percent reduction and raw score cutoffs on the parent- and child-report Screen for Child Anxiety Related Emotional Disorders (SCARED) for predicting treatment response and remission among youth with anxiety disorders.

METHOD

Data were obtained from youth (N = 438; 7-17 years old) who completed treatment in the Child/Adolescent Anxiety Multimodal treatment Study, a multisite, randomized clinical trial that examined the relative efficacy of medication (sertraline), cognitive-behavioral therapy (Coping Cat), their combination, and pill placebo for the treatment of separation anxiety disorder, generalized anxiety disorder, and social phobia. The parent- and youth-report SCARED were administered at pre- and posttreatment. Quality receiver operating characteristic methods evaluated the performance of various SCARED percent reduction and absolute cutoff scores in predicting treatment response and remission, as defined by posttreatment ratings on the Clinical Global Impression scales and the Anxiety Disorders Interview Schedule.

RESULTS

Reductions of 55% on the SCARED-Parent and 50% on the SCARED-Youth optimally predicted treatment response. Posttreatment absolute raw scores of 10 (SCARED-Parent) and 12 (SCARED-Youth) optimally predicted remission in the total sample, although separate SCARED-Parent cutoffs for children (12-13) and adolescents (9) showed greatest quality of efficiency. Each cutoff significantly predicted response and remission at 6-month follow-up.

CONCLUSION

Results serve as guidelines for operationalizing treatment response and remission on the SCARED, which could help clinicians systematically monitor treatment outcomes of youth with anxiety disorders in a cost- and time-efficient manner.

Placebo Response in Pediatric Anxiety Disorders: Results from the Child/Adolescent Anxiety Multimodal Study

OBJECTIVES

The aim of this study is to identify predictors of pill placebo response and to characterize the temporal course of pill placebo response in anxious youth.

METHODS

Data from placebo-treated patients (N = 76) in the Child/Adolescent Anxiety Multimodal Study (CAMS), a multisite, randomized controlled trial that examined the efficacy of cognitive-behavioral therapy, sertraline, their combination, and placebo for the treatment of separation, generalized, and social anxiety disorders, were evaluated. Multiple linear regression models identified features associated with placebo response and models were confirmed with leave-one-out cross-validation. The likelihood of improvement in patients receiving pill placebo-over time-relative to improvement associated with active treatment was determined using probabilistic Bayesian analyses.

RESULTS

Based on a categorical definition of response (Clinical Global Impressions-Improvement Scale score ≤2), nonresponders (n = 48), and pill placebo responders (n = 18) did not differ in age (p = 0.217), sex (p = 0.980), race (p = 0.743), or primary diagnosis (all ps > 0.659). In terms of change in anxiety symptoms, separation anxiety disorder and treatment expectation were associated with the degree of pill placebo response. Greater probability of placebo-related anxiety symptom improvement was observed early in the course of treatment (baseline to week 4, p < 0.0001). No significant change in the probability of placebo-related improvement was observed after week 4 (weeks 4-8, p = 0.07; weeks 8-12, p = 0.85), whereas the probability of improvement, in general, significantly increased week over week with active treatment.

CONCLUSIONS

Pill placebo-related improvement occurs early in the course of treatment and both clinical factors and expectation predict this improvement. Additionally, probabilistic approaches may refine our understanding and prediction of pill placebo response.

Social Interpretation Bias in Children and Adolescents with Anxiety Disorders: Psychometric Examination of the Self-report of Ambiguous Social Situations for Youth (SASSY) Scale

BACKGROUND

Anxiety disorders are among the most common mental health problems in youth, and faulty interpretation bias has been positively linked to anxiety severity, even within anxiety-disordered youth. Quick, reliable assessment of interpretation bias may be useful in identifying youth with certain types of anxiety or assessing changes on cognitive bias during intervention.

OBJECTIVE

This study examined the factor structure, reliability, and validity of the Self-report of Ambiguous Social Situations for Youth (SASSY) scale, a self-report measure developed to assess interpretation bias in youth.

METHODS

Participants (N=488, age 7 to 17) met diagnostic criteria for Social Phobia, Generalized Anxiety Disorder, and/or Separation Anxiety Disorder. An exploratory factor analysis was performed on baseline data from youth participating in a large randomized clinical trial.

RESULTS

Exploratory factor analysis yielded two factors (Accusation/Blame, Social Rejection). The SASSY full scale and Social Rejection factor demonstrated adequate internal consistency, convergent validity with social anxiety, and discriminant validity as evidenced by non-significant correlations with measures of non-social anxiety. Further, the SASSY Social Rejection factor accurately distinguished children and adolescents with Social Phobia from those with other anxiety disorders, supporting its criterion validity, and revealed sensitivity to changes with treatment. Given the relevance to youth with social phobia, pre- and post-intervention data were examined for youth social phobia to test sensitivity to treatment effects; results suggested that SASSY scores reduced for treatment responders.

CONCLUSIONS

Findings suggest the potential utility of the SASSY Social Rejection factor as a quick, reliable, and efficient way of assessing interpretation bias in anxious youth, particularly as related to social concerns, in research and clinical settings.

Child and Adolescent Adherence With Cognitive Behavioral Therapy for Anxiety: Predictors and Associations With Outcomes

Cognitive behavioral therapy (CBT) for anxiety disorders is effective, but nonadherence with treatment may reduce the benefits of CBT. This study examined (a) four baseline domains (i.e., demographic, youth clinical characteristics, therapy related, family/parent factors) as predictors of youth adherence with treatment and (b) the associations between youth adherence and treatment outcomes. Data were from 279 youth (7-17 years of age, 51.6% female; 79.6% White, 9% African American), with Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.) diagnoses of separation anxiety disorder, generalized anxiety disorder, and/or social phobia, who participated in CBT in the Child/Adolescent Anxiety Multimodal Study. Adherence was defined in three ways (session attendance, therapist-rated compliance, and homework completion). Multiple regressions revealed several significant predictors of youth adherence with CBT, but predictors varied according to the definition of adherence. The most robust predictors of greater adherence were living with both parents and fewer youth comorbid externalizing disorders. With respect to outcomes, therapist ratings of higher youth compliance with CBT predicted several indices of favorable outcome: lower anxiety severity, higher global functioning, and treatment responder status after 12 weeks of CBT. Number of sessions attended and homework completion did not predict treatment outcomes. Findings provide information about risks for youth nonadherence, which can inform treatment and highlight the importance of youth compliance with participating in therapy activities, rather than just attending sessions or completing homework assignments.

Perceived Peer Victimization Predicts Anxiety Outcomes in a Prevention Program for Offspring of Anxious Parents

Offspring of anxious parents are at heightened risk for developing anxiety disorders. Preventive interventions for these youths are promising but not universally effective, creating a need to identify outcome predictors. Peer experiences (e.g., peer victimization, social support) are associated with youth anxiety trajectories but have been relatively unexplored in this context. Thus, this study tested whether peer experiences predicted anxiety-related outcomes in families participating in a randomized controlled trial of a child anxiety prevention program for families with a clinically anxious parent. Parental anxiety severity was also examined as a moderator of relations between peer experiences and subsequent child anxiety. Participants were 121 families (child M age = 8.69, 55.90% girls). Hierarchical logistic and linear regressions were used to test whether baseline peer-related factors predicted increased anxiety symptom severity and anxiety disorder onset over 12 months. Youths reporting greater perceived peer victimization at baseline were more likely to develop an anxiety disorder and had more severe anxiety symptoms 12 months later. Lower social support from classmates also predicted increased anxiety severity, but this effect became nonsignificant after accounting for peer victimization. Further, parental anxiety severity moderated the peer victimization-child anxiety severity link: Higher child-reported peer victimization predicted increased anxiety in offspring of highly and moderately anxious but not low anxious parents. Children's reports of peer victimization appear important for understanding which youth may not respond to preventive interventions in high-risk families-especially for children with more severely anxious parents. Implications for the focus of selective anxiety prevention programs are discussed.

Somatic Symptoms and Anxiety Among African American Adolescents

Somatic symptoms are an associated feature of anxiety disorders that have received little research attention among non-White samples. In addition, the majority of previous studies have examined the influence of somatic symptoms in a cross-sectional rather than a prospective manner. This study examines the prevalence of 12 somatic symptoms, the association of somatic and anxiety symptoms (both concurrently and prospectively) with psychosocial functioning, and gender differences in somatic symptoms among a community sample of 114 African American adolescents (57 girls). In all, 83% of the sample reported at least one somatic symptom (some or most of the time within the past 2 weeks), and on average, adolescents reported 2.5 somatic symptoms. Somatic symptoms correlated positively with severity of anxiety symptoms and negatively with aspects of perceived competence. After the initial level of anxiety symptoms was controlled for, somatic symptoms were a unique predictor of perceived competence (at initial assessment) and anxiety symptoms (at 6-month follow-up). Overall, girls endorsed significantly more somatic symptoms than did boys. Findings replicate those of studies with White samples and suggest that somatic symptoms may be a risk factor for anxiety disorders among African American youth.

All anxiety is not created equal: Correlates of parent/youth agreement vary across subtypes of anxiety

Research has examined patterns and correlates of parent/youth informant discrepancies in the reporting of youth anxiety. However, little work has examined whether it is better to conceptualize patterns and correlates of informant disagreement across anxiety broadly, or more useful to consider disagreement on specific symptom clusters. Using data from the Child Adolescent/Anxiety Multimodal Study (CAMS; N = 488; Walkup et al., 2008), the current study applied the most recent recommended analytic strategies to study informant discrepancies and examined differences in the magnitude and patterns of disagreement for: (a) broadband anxiety symptoms, versus (b) symptoms of specific anxiety diagnoses (or anxiety subtypes; e.g., separation, social anxiety). Correlates of informant discrepancies were also examined. Results indicated that there was variability in agreement across anxiety subtypes, with parent/youth agreement higher on separation anxiety and school refusal symptoms relative to other domains. Parental psychopathology was associated with disagreement on broadband anxiety symptoms, such that parental psychopathology was highest when parents reported higher symptoms than their children; however, this finding was largely driven by a relationship between parental psychopathology and disagreement on separation anxiety symptoms. Age was associated with disagreement on total and separation anxiety symptoms. Gender was not associated with disagreement. Clinical implications are discussed.

Differential evolution of peripheral cytokine levels in symptomatic and asymptomatic responses to experimental influenza virus challenge

Exposure to influenza virus triggers a complex cascade of events in the human host. In order to understand more clearly the evolution of this intricate response over time, human volunteers were inoculated with influenza A/Wisconsin/67/2005 (H3N2), and then had serial peripheral blood samples drawn and tested for the presence of 25 major human cytokines. Nine of 17 (53%) inoculated subjects developed symptomatic influenza infection. Individuals who will go on to become symptomatic demonstrate increased circulating levels of interleukin (IL)-6, IL-8, IL-15, monocyte chemotactic protein (MCP)-1 and interferon (IFN) gamma-induced protein (IP)-10 as early as 12-29 h post-inoculation (during the presymptomatic phase), whereas challenged patients who remain asymptomatic do not. Overall, the immunological pathways of leucocyte recruitment, Toll-like receptor (TLR)-signalling, innate anti-viral immunity and fever production are all over-represented in symptomatic individuals very early in disease, but are also dynamic and evolve continuously over time. Comparison with simultaneous peripheral blood genomics demonstrates that some inflammatory mediators (MCP-1, IP-10, IL-15) are being expressed actively in circulating cells, while others (IL-6, IL-8, IFN-α and IFN-γ) are probable effectors produced locally at the site of infection. Interestingly, asymptomatic exposed subjects are not quiescent either immunologically or genomically, but instead exhibit early and persistent down-regulation of important inflammatory mediators in the periphery. The host inflammatory response to influenza infection is variable but robust, and evolves over time. These results offer critical insight into pathways driving influenza-related symptomatology and offer the potential to contribute to early detection and differentiation of infected hosts.

Preventing Onset of Anxiety Disorders in Offspring of Anxious Parents: A Randomized Controlled Trial of a Family-Based Intervention

OBJECTIVE

The authors examined the efficacy of a family-based intervention to prevent the onset of anxiety disorders in offspring of anxious parents.

METHOD

Participants were 136 families with a parent meeting DSM-IV criteria for an anxiety disorder and one child 6-13 years of age without an anxiety disorder. Families were randomly assigned to the family-based intervention (N=70) or to an information-monitoring control condition (N=66). All families were expected to complete assessments, administered by blind interviewers, at baseline, at the end of the intervention (or 8 weeks after randomization) and at 6- and 12-month follow-ups. Onset of any anxiety disorder and anxiety symptom severity (assessed using the Anxiety Disorders Interview Schedule for Children) at 12 months were the primary and secondary outcome measures, respectively.

RESULTS

The incidence of child anxiety disorders was 31% in the control group and 5% in the intervention group (odds ratio=8.54, 95% CI=2.27, 32.06). At the 1-year follow-up, youths in the control group also had higher anxiety symptoms ratings than those in the intervention group. Effect sizes were medium to large (0.81 at 6 months and 0.57 at 12 months for anxiety symptoms), and the number needed to treat was 3.9 at 12 months. Significant moderators included baseline levels of child anxiety; significant mediators were parental distress and modeling of anxiety. Child maladaptive cognitions and parental anxiety did not mediate outcomes.

CONCLUSIONS

A brief psychosocial prevention program holds promise for reducing the 1-year incidence of anxiety disorders among offspring of anxious parents.
