Therapy for youths with anxiety disorders : A second randomized clinical trial

Ninety-four children (aged 9-13 years) with anxiety disorders were randomly assigned to cognitive behavioral treatment or waiting-list control. Outcomes were evaluated using diagnostic status, child self-reports, parent and teacher reports, cognitive assessment and behavioral observation: maintenance was examined using 1-year follow-up data. Analyses of dependent measures indicated significant improvements over time, with the majority indicating greater gains for those receiving treatment. Treatment gains returned cases to within nondeviant limits (i.e., normative comparisons) and were maintained at 1-year follow-up. Client age and comorbid status did not moderate outcomes. A preliminary examination of treatment segments suggested that the enactive exposure (when it follows cognitive-educational training) was an active force in beneficial change. Discussion includes suggestions for future research.

Behavioral Inhibition in Preschool Children At Risk Is a Specific Predictor of Middle Childhood Social Anxiety: A Five-year Follow-up

Objective: Behavioral inhibition (BI) to the unfamiliar represents the temperamental tendency to exhibit fearfulness, reticence, or restraint when faced with unfamiliar people or situations. It has been hypothesized to be a risk factor for anxiety disorders. In this prospective longitudinal study, we compared the psychiatric outcomes in middle childhood of children evaluated at preschool age for BI. Method: The baseline sample consisted of 284 children ages 21 months to 6 years, including offspring at risk for anxiety (children of parents with panic disorder and/or major depression) and comparison offspring of parents without mood or major anxiety disorders. They had been assessed for BI using age-specific laboratory protocols. We reassessed 215 of the children (76.5%) at 5-year follow-up at a mean age of 9.6 years using structured diagnostic interviews. Results: BI specifically predicted onset of social anxiety. The rate of lifetime social anxiety (DSM-IV social phobia or DSM-III-R avoidant disorder) was 28% versus 14% (odds ratio [OR] = 2.37; 95% confidence interval [CI]: 1.10–5.10) in inhibited versus noninhibited children. BI significantly predicted new onset of social phobia among children unaffected at baseline (22.2% vs 8.0% in inhibited versus noninhibited children (OR = 3.15, 95% CI: 1.16–8.57). No other anxiety disorders were associated with BI. Conclusion: BI appears to be a temperamental antecedent to subsequent social anxiety in middle childhood. Children presenting with BI should be monitored for symptoms of social anxiety and may be good candidates for preventive cognitive behavioral strategies.

Psychopathology in the Offspring of Parents with Bipolar Disorder: A Controlled Study

BACKGROUND To examine the risk for psychopathology in offspring at risk for bipolar disorder and the course of psychiatric disorders in these youth. METHODS Using structured diagnostic interviews (Structured Clinical Interview for DSM-IV [SCID] and Kiddie Schedule for Affective Disorders and Schizophrenia [K-SADS]), psychiatric diagnoses of 117 nonreferred offspring of parents with diagnosed bipolar disorder were compared with those of 171 age- and gender-matched offspring of parents without bipolar disorder or major depression. RESULTS Compared with offspring of parents without mood disorders, high-risk youth had elevated rates of major depression and bipolar disorder, anxiety, and disruptive behavior disorders. High-risk offspring also had significantly more impaired Global Assessment of Functioning (GAF) scores, higher rates of psychiatric treatment, and higher rates of placement in special education classes. Disruptive behavior disorders, separation anxiety disorder, generalized anxiety disorder (GAD), social phobia, and depression tended to have their onset in early or middle childhood, whereas bipolar disorder, obsessive-compulsive disorder (OCD), panic disorder, and substance use disorder had onset most frequently in adolescence. CONCLUSIONS These findings support the hypothesis that offspring of parents with bipolar disorder are at significantly increased risk for developing a wide range of severe psychiatric disorders and accompanying dysfunction. Early disruptive behavior and anxiety disorders, as well as early-onset depression, may be useful markers of risk for subsequent bipolar disorder in high-risk samples.

A Preliminary Study of D-Cycloserine Augmentation of Cognitive-Behavioral Therapy in Pediatric Obsessive-Compulsive Disorder

BACKGROUND Research on the neural circuitry underlying fear extinction has led to the examination of D-cycloserine (DCS), a partial agonist at the N-methyl-D-aspartate receptor in the amygdala, as a method to enhance exposure therapy outcome. Preliminary results have supported the use of DCS to augment exposure therapy in adult anxiety disorders; however, no data have been reported in any childhood anxiety disorder. Thus, we sought to preliminarily examine whether weight-adjusted DCS doses (25 or 50 mg) enhanced the overall efficacy of cognitive-behavioral therapy (CBT) for pediatric obsessive-compulsive disorder (OCD). METHOD Participants were 30 youth (aged 8-17) with a primary diagnosis of OCD. The study design was a randomized, double-blinded, placebo-controlled augmentation trial examining CBT + DCS versus CBT + Placebo (15 youth per group). All patients received seven exposure and response prevention sessions paired with DCS or placebo taken 1 hour before sessions. RESULTS Although not significantly different, compared with the CBT + Placebo group, youth in the CBT + DCS arm showed small-to-moderate treatment effects (d = .31-.47 on primary outcomes). No adverse events were recorded. CONCLUSIONS These results complement findings in adult OCD and non-OCD anxiety disorders and provide initial support for a more extensive study of DCS augmentation of CBT among youth with OCD.

Cognitive Behavioral Therapy for 4- to 7-Year-Old Children with Anxiety Disorders: A Randomized Clinical Trial.

OBJECTIVE To examine the efficacy of a developmentally appropriate parent-child cognitive behavioral therapy (CBT) protocol for anxiety disorders in children ages 4-7 years. METHOD DESIGN Randomized wait-list controlled trial. Conduct: Sixty-four children (53% female, mean age 5.4 years, 80% European American) with anxiety disorders were randomized to a parent-child CBT intervention (n = 34) or a 6-month wait-list condition (n = 30). Children were assessed by interviewers blind to treatment assignment, using structured diagnostic interviews with parents, laboratory assessments of behavioral inhibition, and parent questionnaires. ANALYSIS Chi-square analyses of outcome rates and linear and ordinal regression of repeated measures, examining time by intervention interactions. RESULTS The response rate (much or very much improved on the Clinical Global Impression Scale for Anxiety) among 57 completers was 69% versus 32% (CBT vs. controls), p < .01; intent-to-treat: 59% vs. 30%, p = .016. Treated children showed a significantly greater decrease in anxiety disorders (effect size [ES] = .55) and increase in parent-rated coping (ES = .69) than controls, as well as significantly better CGI improvement on social phobia/avoidant disorder (ES = .95), separation anxiety disorder (ES = .82), and specific phobia (ES = .78), but not on generalized anxiety disorder. Results on the Child Behavior Checklist Internalizing scale were not significant and were limited by low return rates. Treatment response was unrelated to age or parental anxiety but was negatively predicted by behavioral inhibition. Gains were maintained at 1-year follow-up. CONCLUSIONS Results suggest that developmentally modified parent-child CBT may show promise in 4- to 7-year-old children.

High risk studies and developmental antecedents of anxiety disorders

The past two decades have witnessed significant growth in our understanding of the developmental antecedents of anxiety disorders. In this article, we review studies of offspring at risk for anxiety disorders, longitudinal studies of the course of anxiety disorders in clinical, epidemiologic, and at‐risk samples, studies of hypothesized temperamental risk factors for anxiety, and give a brief overview of the literature on environmental risk factors. Clear developmental antecedents to anxiety disorders identified include (1) childhood anxiety disorders [in particular, separation anxiety and overanxious disorder/general anxiety disorder (GAD)], (2) behavioral inhibition which predicts later social phobia, (3) anxiety sensitivity which predicts later panic disorder, and (4) negative affectivity, which predicts a spectrum of psychopathology including anxiety disorders. Further prospective studies are needed to examine the roles of environmental factors such as parenting practices, peer influences, stressful life events, and perinatal stressors. Future studies could benefit from (1) beginning earlier in development and following individuals into adulthood, (2) assessing the overlap between multiple temperamental constructs, (3) greater use of observational measures of temperament and of parent–child and peer interactions, (4) greater attention to parental psychopathology which may confound associations noted, (5) exploration of other features of anxiety disorders (neurofunctional correlates, cognitive features, other aspects of emotional regulation) as potential precursors, and (6) intervention studies exploring whether modifying developmental antecedents can alter the course of anxiety disorders.

Effectiveness of collaborative problem solving in affectively dysregulated children with oppositional-defiant disorder: initial findings.

Oppositional-defiant disorder (ODD) refers to a recurrent pattern of negativistic, defiant, disobedient, and hostile behavior toward authority figures. Research has shown that children with ODD and comorbid mood disorders may be at particular risk for long-term adverse outcomes, including conduct disorder. In this study, the authors examined the effectiveness of a cognitive-behavioral model of intervention--called collaborative problem solving (CPS)--in comparison with parent training (PT) in 47 affectively dysregulated children with ODD. Results indicate that CPS produced significant improvements across multiple domains of functioning at posttreatment and at 4-month follow-up. These improvements were in all instances equivalent, and in many instances superior, to the improvements produced by PT. Implications of these findings for further research on and treatment selection in children with ODD are discussed.

Psychopathology in the young offspring of parents with bipolar disorder: A controlled pilot study

Studies have suggested that the offspring of parents with bipolar disorder are at risk for a spectrum of psychopathology, but few have focused on children in the youngest age ranges or examined the impact of comorbid parental disorders. We utilized a pre-existing sample of young (mean age: 6.8 years) offspring of parents with bipolar disorder (n=34), of parents with panic or major depression (n=179), and of parents with neither mood or anxiety disorder (n=95). Children were assessed blindly to parental diagnoses using the Schedule for Affective Disorders and Schizophrenia-Epidemiologic version (K-SADS-E). Offspring of bipolar parents had significantly higher rates of disruptive behavior and anxiety disorders than offspring from both of the comparison groups, accounted for by elevated rates of ADHD and overanxious disorder. These comparisons were significant even when lifetime histories of the corresponding categories of comorbid disorders in the parents (disruptive behavior disorders and anxiety disorders) were covaried. In addition, offspring of bipolar parents had increased rates of bipolar I disorder, compared with psychiatric controls. Results support the hypotheses of elevated behavior, anxiety, and mood disorders among offspring at risk for bipolar disorder, and suggest that this psychopathology is already evident in early childhood.

Anxiety and depressive disorders in offspring at high risk for anxiety: A meta-analysis

This paper presents a meta-analysis of studies examining prevalence of psychopathology among offspring of anxiety-disordered parents, with the purpose of determining overall risk among these offspring for developing anxiety and depressive disorders. Pooled odds ratios for these disorders among high-risk offspring, compared to offspring of psychiatric and non-psychiatric controls, were calculated. Sixteen papers (including three follow-up studies) were identified, encompassing 1892 offspring (ages 4-25 years). Results revealed that: (1) offspring of parents with anxiety disorders have greater risk for anxiety and depressive disorders than offspring of non-psychiatric controls (ORs=3.91 and 2.67, respectively) and greater risk for anxiety disorders than offspring of psychiatric controls (OR=1.84); (2) offspring of anxious parents have significantly greater odds of having each type of anxiety disorder and MDD compared to offspring of non-psychiatric controls (ORs range from 1.96 to 8.69); and (3) offspring of parents with anxiety only, anxiety plus MDD, and MDD only have similar odds of having anxiety and depressive disorders but significantly higher odds than offspring of parents without disorder. Results suggest that parental anxiety disorders confer significant risk for anxiety and depression in offspring. Additional studies are needed to examine whether there are differences among specific parental anxiety disorders.

Can bipolar disorder-specific neuropsychological impairments in children be identified?

This study examined neuropsychological deficits among children with bipolar disorder while attending to its comorbidity with attention-deficit/hyperactivity disorder (ADHD). Seventy-three unmedicated children (ages 6-17 years) with Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) bipolar disorder plus ADHD (BPD + ADHD) were compared with 102 unmedicated children with ADHD without bipolar disorder, and 120 children without bipolar disorder or ADHD. Ninety-four percent of participants were Caucasian, 58% were male, and 42% were female. On average participants were of middle to upper socioeconomic status. Participants were assessed with a comprehensive neuropsychological battery and measures of academic achievement, school failure, and special education placement. Participants with BPD + ADHD and with ADHD were impaired in interference control, verbal learning, and arithmetic achievement and had higher rates of special school services. Across all of the measures of neuropsychological functioning, the only difference observed between youths with BPD + ADHD and youths with ADHD was that youths with BPD + ADHD performed more poorly on one measure of processing speed. Thus, comorbidity with ADHD may account for many of the neuropsychological deficits observed in children with bipolar disorder.
