Anxiety Disorders During Childhood and Adolescence: Origins and Treatment

The present review summarizes our current knowledge of the development and management of anxiety in children and adolescents. Consideration is given to limitations of this knowledge and directions for future research. The review begins with coverage of the development and demographic correlates of anxiety in young people and then moves to systematic discussion of some of the key etiological factors, including genetics, temperament, parenting, and individual experiences. The second part of the review describes current treatment strategies and efficacy as well as factors thought to influence treatment outcome, including treatment features, child factors, and parent factors. The review concludes with brief coverage of some more recent developments in treatment including alternative models of delivery and prevention strategies.

Development and validation of a measure of children's automatic thoughts: the children's automatic thoughts scale.

The aim of this study was to describe the history, factor structure and psychometric properties of the Childrens Automatic Thoughts Scale (CATS). The CATS is a self-report measure designed to assess a wide range of negative self-statements in children and adolescents. The results of confirmatory factor analyses supported four distinct but strongly correlated factors relating to automatic thoughts on physical threat, social threat, personal failure and hostility. The internal consistency of the total score and subscales was high and test-retest reliability at 1 and 3 months was acceptable. The CATS effectively discriminated between control children and adolescents, and clinically anxious, depressed, or behavior disorder children and adolescents, and showed good discriminant validity across clinical subgroups on the subscales. Results suggest that the CATS is a promising instrument in the assessment of a range of negative automatic thoughts across both internalizing and externalizing problems in young people.

Issues in the diagnosis and assessment of anxiety disorders in children and adolescents

Accurate diagnosis and assessment of anxiety disorders in children and adolescents is important for both treatment and research. In this paper, we review research related to the discriminant validity of the childhood anxiety disorders, and outline methods of assessment for children, including diagnostic interviews, self-report instruments, and behavioural, cognitive, and psychophysiological measures. Particular attention is given to psychometric and developmental issues, and their influence on assessment. The evidence provides support for the validity of the anxiety disorders as a whole, but only partial support for differentiation between specific anxiety disorders in children. Similarly, assessment methods used with anxious children provide reasonably accurate information on anxious symptoms, however are limited by poor discriminant validity and lack of sensitivity to developmental levels.

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.

The relationship between automatic thoughts and negative emotions in children and adolescents: A test of the cognitive content-specificity hypothesis

The aim of this study was to test the cognitive content-specificity hypothesis in children and adolescents aged 7-16 years. Participants consisted of a community sample of 200 youth and a clinical sample of 160 youth with anxiety, depressive, or disruptive behavior disorders. Participants completed several self-report measures assessing a wide range of negative beliefs and symptoms of internalizing and externalizing problems. Multivariate analyses examining the interrelationships between beliefs and noncognitive symptoms revealed that thoughts on loss or personal failure were the strongest predictors of depressive symptoms, thoughts on social threat were the strongest predictors of anxiety symptoms, and thoughts on hostility or revenge were the strongest predictors of aggression. Results showed clear evidence of cognitive-affective specificity across both internalizing and externalizing problems in youth.

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.

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.

The sleep patterns and problems of clinically anxious children

Childhood sleep problems have been associated with a range of adverse cognitive and academic outcomes, as well as increased impulsivity and emotional disorders such as anxiety and depression. The aim of the study was to examine subjective reports of sleep-related problems in children with anxiety disorders during school and weekend nights. Thirty-seven children with clinically-diagnosed anxiety disorders and 26 non-clinical children aged 7-12 years completed an on-line sleep diary to track sleep patterns across school nights and weekend nights. Anxious children reported going to bed significantly later (p=0.03) and had significantly less sleep (p=0.006) on school nights compared to non-anxious children. No significant differences in sleep onset latency, number of awakenings or time awake during the night, daytime sleepiness, or fatigue were found between the two groups. On the weekends, anxious children fell asleep quicker and were less awake during the night than on weeknights. School-aged anxiety disordered children showed a sleep pattern that differs from their non-anxious peers. Although the mean 30 min less sleep experienced by anxious children may initially seem small, the potential consequences on daytime performance from an accumulation of such a sleep deficit may be significant, and further investigation is warranted.

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.

Lessons learned on lead poisoning in children: one-hundred years on from Turner's declaration.

There is significant emerging evidence showing life‐long negative health, intellectual and socio‐behavioural impacts as a result of childhood blood lead concentrations well below the widely used intervention level of 10 µg/dL. This issue raises serious health concerns for children in several Australian smelting and mining towns. Routine educational and home cleanliness advice to wet mop floors rather than to use a brush and pan to reduce lead exposure risks have been shown to have limited efficacy. This paper argues, as advocated 100 years ago by Queensland doctor Alfred Jefferis Turner, that childhood lead poisoning can only be mitigated via primary prevention and reduction of contaminants at source. Given that the effects of lead exposure are irreversible, there is a strong argument for the application of the precautionary principle to dealing with childhood lead exposure. There is a clear need to improve regulatory controls and emissions management to reduce environmental lead exposure risks.
