Agreement between Telephone and In-Person Delivery of a Structured Interview for Anxiety Disorders in Children.

OBJECTIVE The current study determined the viability of using the telephone to facilitate assessment of children using the Anxiety Disorders Interview Schedule for children for DSM-IV (ADIS-C-IV). METHOD Diagnoses established during telephone administration of the ADIS-C-IV-Parent version were compared with diagnoses obtained during standard administration of the ADIS-C-IV using both Child and Parent versions. Seventy-three children and their parents participated in counterbalanced, repeated assessments. RESULTS The level of agreement between telephone and standard administration for principal diagnosis (kappa=0.86), individual anxiety disorders (kappa=0.63-0.86), and other disorders (kappa=0.79-0.91) were in the good to excellent range. Additionally, agreement on overall suitability for an anxiety treatment program was excellent (kappa=0.97). CONCLUSIONS The data indicate that telephone administration of the ADIS-C-IV is a valid way to differentiate children who have anxiety disorders from those who have no disorder or other disorders, providing a less resource-demanding alternative to face-to-face assessment.

Bibliotherapy for children with anxiety disorders using written materials for parents: A randomized controlled trial

The current trial examined the value of modifying empirically validated treatment for childhood anxiety for application via written materials for parents of anxious children. Two hundred sixty-seven clinically anxious children ages 6-12 years and their parents were randomly allocated to standard group treatment, waitlist, or a bibliotherapy version of treatment for childhood anxiety. In general, parent bibliotherapy demonstrated benefit for children relative to waitlist but was not as efficacious as standard group treatment. Relative to waitlist, use of written materials for parents with no therapist contact resulted in around 15% more children being free of an anxiety disorder diagnosis after 12 and 24 weeks. These results have implications for the dissemination and efficient delivery of empirically validated treatment for childhood anxiety.

Therapygenetics: the 5HTTLPR and response to psychological therapy

Whilst pharmacogenetic research thrives 1 , genetic determinants of response to purely psychotherapeutic treatments remain unexplored. In a sample of children undergoing Cognitive Behavior Therapy (CBT) for an anxiety disorder, we tested whether treatment response is associated with the serotonin transporter gene promoter region (5HTTLPR), previously shown to moderate environmental influences on depression. Children with the short-short genotype were significantly more likely to respond to CBT than those carrying a long allele.

Cognitive-behavioral treatment versus an active control for children and adolescents with anxiety disorders: a randomized trial.

OBJECTIVE The current trial examined whether a specific cognitive-behavioral treatment package was more efficacious in treating childhood anxiety disorders than a nonspecific support package. METHOD One hundred twelve children (aged 7-16 years) with a principal anxiety disorder were randomly allocated to either a group cognitive-behavioral treatment (CBT) program or a control condition (group support and attention [GSA]). RESULTS Overall, results showed that CBT was significantly more efficacious compared with the GSA condition: 68.6% of children in the CBT condition did not meet diagnostic criteria for their principal anxiety diagnosis at 6-month follow-up compared with 45.5% of the children in the GSA condition. The results of the child- and parent-completed measures indicated that, although mothers of CBT children reported significantly greater treatment gains than mothers of GSA children, children reported similar improvements across conditions. CONCLUSIONS Specific delivery of cognitive-behavioral skills is more efficacious in the treatment of childhood anxiety than a treatment that includes only nonspecific therapy factors.

A Randomized Controlled Trial of the Cool Teens CD-ROM Computerized Program for Adolescent Anxiety

OBJECTIVE Computerized cognitive behavioral interventions for anxiety disorders in adults have been shown to be efficacious, but limited data are available on the use of computerized interventions with young persons. Adolescents in particular are difficult to engage in treatment and may be especially suited to computerized technologies. This paper describes the results of a small randomized controlled trial of the Cool Teens program for adolescent anxiety, and examines potential barriers to treatment and user preferences of computerized technology in this population. METHOD Forty-three adolescents with a primary diagnosis of anxiety were randomly allocated to the Cool Teens program, a 12-week computerized cognitive-behavioral therapy program for anxiety management, or a 12-week wait list. Effects on symptoms, negative thoughts, and life interference were assessed at post-treatment and 3-month follow-up, based on diagnosis as well as self and maternal report. RESULTS Using mixed-model analyses, at post-treatment and follow-up assessments, adolescents in the Cool Teens condition, compared with those on the wait list, were found to have significant reductions in the total number of anxiety disorders, the severity of the primary anxiety disorder, and the average severity for all disorders. These results were matched by significant reductions in mother and child questionnaire reports of anxiety, internalizing symptoms, automatic thoughts, and life interference. Further few barriers to treatment were found, and user preferences indicated that the computerized treatment was well suited to adolescents with anxiety. CONCLUSIONS The Cool Teens program is efficacious for treatment of adolescent anxiety.

Temperament and Family Environment in the Development of Anxiety Disorder: Two-Year Follow-up

OBJECTIVE Behavioral inhibition (BI) in early childhood is associated with increased risk for anxiety. The present research examines BI alongside family environment factors, specifically maternal negativity and overinvolvement, maternal anxiety, and mother-child attachment, with a view to providing a broader understanding of the development of child anxiety. METHOD Participants were 202 children classified at age 4 years as either behaviorally inhibited (N = 102) or behaviorally uninhibited (N = 100). Family environment, BI and child anxiety were assessed at baseline and child anxiety and BI were assessed again 2 years later when participants were 6 years of age. RESULTS After controlling for baseline anxiety, BI participants were significantly more likely to meet criteria for a diagnosis of social phobia and generalized anxiety disorder at follow-up. Path analysis suggested that maternal anxiety significantly affected child anxiety over time, even after controlling for the effects of BI and baseline anxiety. No significant paths from parenting or attachment to child anxiety were found. Maternal overinvolvement was significantly associated with BI at follow-up. CONCLUSIONS At age 4 years, BI, child anxiety, maternal anxiety, and maternal overinvolvement represent risk factors for anxiety at age 6 years. Furthermore, overinvolved parenting increases risk for BI at age 6, which may then lead to the development of anxiety in later childhood.

A Model of therapist competencies for the empirically supported cognitive behavioral treatment of child and adolescent anxiety and depressive disorders

While a plethora of cognitive behavioral empirically supported treatments (ESTs) are available for treating child and adolescent anxiety and depressive disorders, research has shown that these are not as effective when implemented in routine practice settings. Research is now indicating that is partly due to ineffective EST training methods, resulting in a lack of therapist competence. However, at present, the specific competencies that are required for the effective implementation of ESTs for this population are unknown, making the development of more effective EST training difficult. This study therefore aimed to develop a model of therapist competencies for the empirically supported cognitive behavioral treatment of child and adolescent anxiety and depressive disorders using a version of the well-established Delphi technique. In doing so, the authors: (1) identified and reviewed cognitive behavioral ESTs for child and adolescent anxiety and depressive disorders, (2) extracted therapist competencies required to implement each treatment effectively, (3) validated these competency lists with EST authors, (4) consulted with a panel of relevant local experts to generate an overall model of therapist competence for the empirically supported cognitive behavioral treatment of child and adolescent anxiety and depressive disorders, and (5) validated the overall model with EST manual authors and relevant international experts. The resultant model offers an empirically derived set of competencies necessary for effectively treating children and adolescents with anxiety and depressive disorders and has wide implications for the development of therapist training, competence assessment measures, and evidence-based practice guidelines for working with this population. This model thus brings us one step closer to bridging the gap between science and practice when treating child and adolescent anxiety and depression.

Clinical Predictors of Response to Cognitive-Behavioral Therapy in Pediatric Anxiety Disorders: The Genes for Treatment (GxT) Study

Objective The Genes for Treatment study is an international, multisite collaboration exploring the role of genetic, demographic, and clinical predictors in response to cognitive-behavioral therapy (CBT) in pediatric anxiety disorders. The current article, the first from the study, examined demographic and clinical predictors of response to CBT. We hypothesized that the child’s gender, type of anxiety disorder, initial severity and comorbidity, and parents’ psychopathology would significantly predict outcome. Method A sample of 1,519 children 5 to 18 years of age with a primary anxiety diagnosis received CBT across 11 sites. Outcome was defined as response (change in diagnostic severity) and remission (absence of the primary diagnosis) at each time point (posttreatment, 3-, 6-, and/or 12-month follow-up) and analyzed using linear and logistic mixed models. Separate analyses were conducted using data from posttreatment and follow-up assessments to explore the relative importance of predictors at these time points. Results Individuals with social anxiety disorder (SoAD) had significantly poorer outcomes (poorer response and lower rates of remission) than those with generalized anxiety disorder (GAD). Although individuals with specific phobia (SP) also had poorer outcomes than those with GAD at posttreatment, these differences were not maintained at follow-up. Both comorbid mood and externalizing disorders significantly predicted poorer outcomes at posttreatment and follow-up, whereas self-reported parental psychopathology had little effect on posttreatment outcomes but significantly predicted response (although not remission) at follow-up. Conclusion SoAD, nonanxiety comorbidity, and parental psychopathology were associated with poorer outcomes after CBT. The results highlight the need for enhanced treatments for children at risk for poorer outcomes.

Effect of Comorbidity on Treatment of Anxious Children and Adolescents: Results from a Large, Combined Sample.

OBJECTIVE The purpose of the present study was to evaluate the influence of comorbid disorders on the degree of change and the endpoint of cognitive-behavioral treatment in anxious young people. METHOD Data on 750 children 6 to 18 years old were compiled from different samples within one clinic. All children had a primary anxiety disorder and were engaged in a manual-based, 10-session, cognitive-behavioral treatment program. Outcome was determined according to diagnostic status and continuous symptom measurements. Analyses compared results among four groups: no comorbidity, comorbid anxiety disorders, comorbid externalizing disorders, comorbid mood disorders. All analyses were intent-to-treat analyses. RESULTS Children with comorbid depression were the least likely to be free of their primary anxiety diagnosis at the end of treatment and follow-up. According to child and maternal reports, symptoms of anxiety decreased similarly over time in all groups, but children with comorbid mood disorders scored significantly highest at all time points. Examining the effects of anxiety treatment on comorbid disorders showed that comorbid mood disorders, but not externalizing disorders, decreased significantly over time. CONCLUSIONS The existence of comorbid disorders does not appear to affect the rate or extent of response to cognitive-behavioral treatment for child anxiety. However, comorbidity has a marked influence on the endpoint of treatment. Children with nonanxiety comorbidity and especially with comorbid mood disorders exhibit greater severity at the outset and remain worse after treatment. On the positive side, treatment for anxiety disorders appears to decrease comorbid mood disorders, although it has less effect on comorbid externalizing disorders.

Neurotrophic gene polymorphisms and response to psychological therapy.

Therapygenetics, the study of genetic determinants of response to psychological therapies, is in its infancy. Here, we investigate whether single-nucleotide polymorphisms in nerve growth factor (NGF) (rs6330) and brain-derived neutrotrophic factor (BDNF) (rs6265) genes predict the response to cognitive behaviour therapy (CBT). Neurotrophic genes represent plausible candidate genes: they are implicated in synaptic plasticity, response to stress, and are widely expressed in brain areas involved in mood and cognition. Allelic variation at both loci has shown associations with anxiety-related phenotypes. A sample of 374 anxiety-disordered children with white European ancestry was recruited from clinics in Reading, UK, and in Sydney, Australia. Participants received manualised CBT treatment and DNA was collected from buccal cells using cheek swabs. Treatment response was assessed at post-treatment and follow-up time points. We report first evidence that children with one or more copies of the T allele of NGF rs6330 were significantly more likely to be free of their primary anxiety diagnosis at follow-up (OR=0.60 (0.42–0.85), P=0.005). These effects remained even when other clinically relevant covariates were accounted for (OR=0.62 (0.41–0.92), P=0.019). No significant associations were observed between BDNF rs6265 and response to psychological therapy. These findings demonstrate that knowledge of genetic markers has the potential to inform clinical treatment decisions for psychotherapeutic interventions.
