Practice parameter for the assessment and treatment of children and adolescents with oppositional defiant disorder.

Oppositional defiant disorder (ODD) is a common clinical problem in children and adolescents. Oppositionality and associated types of aggressive behavior are among the most common referral problems in child psychiatry. Grouped among the disruptive behavior disorders, ODD is frequently comorbid with other psychiatric conditions and often precedes the development of conduct disorder (CD), substance abuse, and severely delinquent behavior. Youth with ODD may also have specific CD behaviors, such as aggression. Although compared with CD there exists a smaller and less sophisticated empirical database for ODD, this parameter draws upon the existing ODD and CD literature to make recommendations regarding diagnosis and treatment of ODD. The etiology of ODD is complex and its development is based on a cumulative risk/protective factor model that combines biological, psychological, and social factors. Recommended treatment is multimodal and extensive, involving individual and family psychotherapeutic approaches, medication, and sociotherapy. Methodologically sound controlled clinical trials are lacking.

Ethnic variation of self-reported psychopathology among incarcerated youth.

Research on ethnic minority populations has shown them to be undertreated, underdiagnosed and perceived as more psychopathological in comparison to the Caucasian population. This study aimed to assess ethnic variation of self-perceived psychopathology in a population of incarcerated youths. The Youth Self-Report (YSR) was completed by 5964 incarcerated adolescents (95% male; mean age = 16.5) in the California Youth Authority (CYA) system. Overall, ethnic minorities (African-Americans and Hispanics) self-report lower levels of psychiatric problems than Caucasians. These differences were more pronounced in males than females. Further research is needed to better ascertain the reasons for these differences.

Hypothalamus pituitary adrenal axis and autonomic activity during stress in delinquent male adolescents and controls.

OBJECTIVE: Patterns of low autonomic arousal have consistently been related to delinquency and disruptive behavior disorders (DBD) in children and adolescents. Findings on another stress regulating mechanism, the hypothalamic pituitary adrenal (HPA) axis, have been inconsistent, which may partly be due to not considering specific stress reactivity measures. Therefore, the aim of the present study was to investigate the relationship between disruptive behavior in male adolescents and their HPA and autonomic reactivity to a standard public speaking task (PST). METHOD: Responsivity to the PST of cortisol, heart rate (HR), skin conductance level (SCL) and self-reported negative feelings was measured, and compared between 12and14-year-old boys who attended a delinquency diversion program (DP), with and without DBD (DP+, n=22 and DP-, n=49, resectively), and matched normal controls (NC, n=30). DBD diagnoses were based on a structured psychiatric interview. RESULTS: The DP+ group, but not the DP- group, showed a significantly decreased cortisol and HR response during the PST as compared with the NC group. No significant effects were found for SCL. All subjects connoted the task negatively. CONCLUSIONS: The results indicate that low cortisol and HR responsivity to stress may be a neurobiological marker for delinquent boys with DBD, but not for those without DBD. Directions for future research and clinical implications are discussed.

Assessing defense structure in school-age children using the Response Evaluation Measure-71-Youth version (REM-Y-71).

This study used the Response Evaluation Measure-Youth (REM-Y-71), a self-report measure of 21 defense reactions, among school-age children. Participants were elementary and middle school students (n = 290; grades 3-8; age range: 8-15; mean = 11.73). Factor analysis revealed a 2-factor defense structure consistent with structure among high school and adult samples. The composite REM-Y defense scores for each factor were significant predictors of social desirability, using the Children's Defensiveness Scale (CDS); anxiety, using the State-Trait Anxiety Inventory for Children (STAIC); and psychosocial functioning. This study represents the first cross-sectional empirical analysis of overall defense structure and use among children and early adolescents.

Efficacy profiles of psychopharmacology: divalproex sodium in conduct disorder.

Little is known about how deeply medication treatment penetrates different levels of the mind/brain system. Psychopathology consists of relatively simple constructs (e.g., anger, irritability), or complex ones (e.g., responsibility). This study examines the efficacy of a specific compound, divalproex sodium (DVPX), on the various levels of psychopathology, utilizing a previous study in which 71 youth with conduct disorder were enrolled in a randomized controlled 7-week clinical trial. We examined weekly slopes of "emotional cognitions" of varying degrees of complexity obtained by Weinberger Adjustment Inventory (WAI), measuring more basic states, such as anger, depression, happiness and anxiety, and complex states, such as impulse control, consideration of others, responsibility and self-esteem. Intent-to-treat analyses showed significant associations between assignment to the active treatment and improvement in depression and impulse control. This is a rare clinical trial, which provides preliminary evidence for the different profiles of efficacy of medication treatment.

Disruptive behaviors: conduct and oppositional disorders in adolescents.

CD and ODD present unique challenges in both the diagnostic and treatment arenas. The complex network of causes leading to disruptive disorders makes it necessary to structure treatment in a multifaceted manner. The earlier that adolescents are identified as exhibiting disruptive behavior disorders, the better the opportunity to intervene. While early-onset CD is very difficult to treat effectively, the disorder is far more difficult to correct if left untreated and can ultimately lead to ASPD in adulthood. When physicians are presented with behavioral complaints, they must fully assess the adolescent to determine what, if any, referrals and treatments are needed.

Psychopharmacologic treatment in juvenile offenders.

This article first reviews ways to assess children in the justice system who may benefit from psychopharmacologic treatments. Second, it summarizes the emerging understanding of the nature of aggression and violence and the utility of using the schema of reactive ("hot") and proactive ("cold") aggression as a way to consider pharmacologic options. Third, it summarizes the current published studies on the treatment of conduct disorder, which roughly corresponds to the population of children in the juvenile justice system. Finally, it examines the ways that different classes of medications might be considered when approaching juvenile delinquents and the ways that psychopharmacology could be used as part of an overall treatment plan.

Divalproex sodium reduces overall aggression in youth at high risk for bipolar disorder.

INTRODUCTION: The psychopharmacology of aggression in youth is relatively unexplored, even though such maladaptive aggression manifests across many different diagnoses. METHODS: This study was a 12-week, open-label trial with divalproex sodium (DVPX) in 24 bipolar offspring 6-18 years of age (mean age = 11.3 years; 17 boys) with mixed diagnoses of major depression, cyclothymia, attention-deficit/hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD). The Overt Aggression Scale (OAS) was used to measure aggression in 4-week intervals. We measured serum gamma-butyric acid (GABA) and glutamate levels at baseline and week 12. RESULTS: Seventy-one percent of evaluable subjects were considered responders to DVPX treatment by the OAS. There was a significant correlation between the Young Mania Rating Scale (YMRS) and OAS scores at week 0 (p = 0.036) and week 12 (p = 0.025). Serum DVPX level did not correlate with treatment response. CONCLUSIONS: These youths who are at high risk for bipolar disorder experienced an overall decrease in aggressive behavior in response to DVPX. Age or gender did not predict a positive response to DVPX. This study is the first report of treatment efficacy of a mood stabilizer for aggression in youth at high risk for bipolar disorder.

Treatment of aggression with risperidone in children and adolescents with bipolar disorder: a case series.

OBJECTIVES: To evaluate the effectiveness and safety of risperidone in children and adolescents with bipolar disorder characterized by aggression and mania, despite treatment with mood stabilizers. METHODS: A retrospective chart review of patients seen in an outpatient pediatric mood disorders clinic over an 18-month period was performed. Data were extracted from charts of patients who had a diagnosis of bipolar disorder with aggression that was uncontrolled on a mood stabilizer; as a result, these patients had risperidone added to their regimen. RESULTS: Four boys (aged 7-15 years) and two girls (aged 8 and 14 years) were treated with risperidone (mean dosage, 0.85 mg/day) for 3-16 months. Aggressive behavior improved in all patients after risperidone was started and remained improved for the duration of follow-up. Other symptoms of mania also improved. Risperidone was generally well tolerated. Sedation and akathisia were reported in one patient. CONCLUSIONS: The addition of risperidone to a mood stabilizer may improve aggression and other symptoms of mania in pediatric patients with bipolar disorder who do not respond adequately to a mood stabilizer alone. The long-term efficacy and safety of this regimen should be evaluated in a controlled clinical trial.

Juvenile maladaptive aggression: a review of prevention, treatment, and service configuration and a proposed research agenda.

OBJECTIVE: To review prevention programs, psychosocial and psychopharmacologic treatments, and service delivery configurations for children and adolescents with maladaptive aggression. To propose a research agenda for disorders of aggression in child and adolescent psychiatry. DATA SOURCES: Recent empirical studies were reviewed using searches of MEDLINE and PsycINFO (text terms: aggression, antisocial, violence, conduct, oppositional, psychosocial treatment, psychopharmacology, and prevention), relevant books, review articles, and bibliographies. DATA EXTRACTION: Articles met the following criteria: published in an English-language, peer-reviewed journal between 1980 and 2005, included a focus on individuals < 18 years old, and included an outcome measure of relevant significance. STUDY SELECTION: Results of 154 randomized, controlled psychosocial treatment trials, 20 controlled psychopharmacology studies, 4 open-label medication studies, and 2 psychopharmacology meta-analyses were reviewed. RESULTS: Prevention programs show promise for reducing future aggression in at-risk populations. Empirical support is available for the effectiveness of multifocused psychosocial treatments in reducing aggression in children and adolescents. Atypical antipsychotics, lithium, divalproex sodium, and stimulants for conduct problems associated with attention-deficit/hyperactivity disorder have empirical support for reducing aggression in selected patient populations. CONCLUSIONS: Therapeutic nihilism in the treatment of aggressive children and adolescents with conduct problems is no longer warranted. Multifocused psychosocial interventions given early in life to at-risk children have the most support for effectiveness. However, treatments for children who routinely present to the child psychiatrist with already well-established disorders of aggression are neither robust nor well-established. Further research into maladaptive aggression in referred children and adolescents within and across psychiatric diagnoses is important for the field of child and adolescent psychiatry.

Heart rate correlates of attachment status in young mothers and their infants.

OBJECTIVE: To explore heart rate (HR) correlates of attachment behavior in young mothers and their infants to generate specific hypotheses and to provide pilot data on which studies to test those hypotheses might be based. METHOD: Using the strange situation procedure, patterns of attachment were assessed in 41 low-income adolescent mothers and their infants. During the procedure, the HRs of the infants and mothers were recorded. The HR changes were analyzed and infant attachment group differences were examined. RESULTS: Infants in all attachment groups demonstrated a similar HR response. There were, however, notably different behavioral reactions in the insecure groups: relatively increased behavioral distress in the insecure/resistant infants and relatively decreased behavioral distress in insecure-avoidant infants. Mothers of insecure-resistant infants demonstrated elevated HRs during reunions and the insecure/resistant dyads demonstrated lower consistency between HR changes in infant and mother than the secure dyads. CONCLUSIONS: The results suggest the discrepancy between attachment-related behavioral reactions and HR response in insecurely attached infants. Maternal and dyadic HR changes vary between the attachment groups.

Divalproex sodium in the treatment of pediatric psychiatric disorders.

Divalproex sodium is an anticonvulsant that is used extensively in adults with indications for epilepsy, acute mania and migraine prophylaxis. It has been used in children and adolescents as a first-line agent for mania in bipolar disorder. Its efficacy as a mood stabilizer has been established, and there have been studies outlining its efficacy as an agent effective in the treatment of conduct disorder, disruptive behavior disorders, aggression and explosive disorder. Longer-acting formulations are now available that cause less gastrointestinal side effects and can also be taken once a day, thus potentially increasing adherence, an important factor in this patient population. Future directions would include developing a more potent valproic acid formulation with fewer side effects, completing randomized controlled trials to establish the efficacy of divalproex sodium in various other pediatric psychiatric disorders, establishing the relative efficacy of the compound in head-to-head comparisons with other mood stabilizers, examining systematically the value of the compound in multimodal pediatric psychiatric treatment packages, and complete effectiveness trials that demonstrate the short- and long-term effectiveness of the compound in the real world of clinicians. In this drug profile, divalproex sodium and its uses in the pediatric population for psychiatric conditions are reviewed.

Baseline predictors of response to divalproex in conduct disorder.

BACKGROUND: Successful treatment of conduct disorder remains difficult. On the basis of a positive response to divalproex among adolescent boys with conduct disorder, we conducted an analysis of the impact of baseline comorbid diagnoses and personality factors on the likelihood of treatment response to divalproex. METHOD: Seventy-one adolescent boys with conduct disorder (DSM-IV) and a history of at least 1 offense against persons were randomly assigned to receive high- or low-dose divalproex for 7 weeks. Evaluations included best estimate diagnoses, the Clinical Global Impressions-Severity of Illness scale (CGI-S) and CGI-Improvement scale (CGI-I), the 62-item Weinberger Adjustment Inventory (WAI-62) assessment of distress and restraint, the Response Evaluation Measure assessment of immature and mature defenses, and the Achenbach Youth Self-Report assessment of overall psychopathology. All were conducted at study entry and exit, and the WAI-62 was conducted weekly throughout the 7-week study period. Treatment response was defined as a rating of much improved or very much improved on the CGI-I. Data were collected from June 1997 to April 1998. RESULTS: Fifty-eight subjects completed the study and were eligible for inclusion in the analysis. Plasma divalproex level (p = .003) and immature defenses (p = .004) were significant positive predictors of treatment response, while restraint (p = .01) and level and range of psychopathology (p = .04) were significant predictors of nonresponse. Comorbidities or distress (p = .06) were not significantly associated with treatment outcome. CONCLUSION: Predictors of response to divalproex treatment for conduct disorder were identified, despite the small sample size in this study. The pattern of positive and negative predictors of response to divalproex, an antikindling agent, tends to support a model of kindling-reinforced reactive/affective/defensive/impulsive aggression among adolescent boys with conduct disorder. Additional studies are needed to identify more subtle predictors of treatment response and to clarify the mechanisms contributing to the development of conduct disorder.

Use of antipsychotics in children and adolescents.

The comparable efficacy and improved safety of the atypical antipsychotics compared with the traditional antipsychotic agents in the treatment of schizophrenia and other disorders in adults have prompted the use of these agents in children and adolescents. The atypical antipsychotics are increasingly being used in children and adolescents with a variety of different psychiatric diagnoses, including schizophrenia, bipolar disorder, autism/pervasive developmental disorders, conduct disorder, depression, anxiety disorders, tic disorders, delirium, and eating disorders. Unfortunately, clinical use of these agents in pediatric patients has far exceeded the limited evidence from randomized controlled trials. This article reviews the available evidence from the published literature on the use of the atypical antipsychotics in children and adolescents with schizophrenia, bipolar disorder, and maladaptive aggression associated with autism/pervasive developmental disorders and conduct disorder/disruptive behavior disorders.

Relationships of dissociation and childhood abuse and neglect with heart rate in delinquent adolescents.

This study examined the relationship of dissociative symptoms, abuse and neglect, and gender to mean heart rate (HR) in two types of interviews. Participants were 25 female and 16 male delinquent adolescents. Dissociative symptoms and abuse and neglect were assessed by structured interviews. Participants were randomized to one of two conditions, to describe either their most stressful life experience or their free association thoughts. Greater dissociative symptoms were associated with lower mean HR, whereas abuse and neglect, being a girl, and participating in the free association task were associated with higher mean HR. The finding that high levels of dissociative symptoms may be related to a suppression of autonomic physiological responses to stress support Bremner's conceptualization (J. D. Bremner, 1999) that dissociative symptoms comprise one of two subtypes of the acute stress response, differing physiologically as well as subjectively from a predominantly hyperarousal or intrusive symptom response.

Psychopharmacologic treatment of aggression in children and adolescents.

Knowledge regarding psychopharmacology is increasingly based on clinical trials and rational algorithms. Medications are increasingly regarded as useful adjuncts in the treatment of maladaptive aggression, whether it appears as a target symptom or as a complication of a whole range of psychopathology. Properly integrated into a treatment package that uses psychotherapies and environmental manipulation, medications can provide relief from one of the most destructive forms of psychopathology. Still, more controlled clinical trials are needed, especially those comparing active interventions and those testing the synergistic and antagonistic effects of different treatment modalities.

Studies of offspring of parents with bipolar disorder.

Children and adolescents who are the biological offspring of individuals with bipolar disorder (BD) (bipolar offspring) represent a population rich in potential for revealing important aspects in the development of BD. Multiple cross-sectional assessments of psychopathology in bipolar offspring have confirmed high incidences of BD, as well as mood and behavioral disorders, and other psychopathology in this population. Longitudinal studies of offspring have begun to shed light on precursors of BD development. Other assessments of bipolar offspring have included dimensional reports of psychiatric and psychosocial functioning, temperament assessments, and descriptions of family environments and parenting styles. Neurobiological studies in bipolar offspring are just beginning to yield findings that may be related to the underlying neuropathophysiology of BD. The future holds promise for longitudinal studies of bipolar offspring incorporating all of these facets, including genetic analyses, to further elucidate the factors involved in the evolution of BD.

Bipolar offspring: a window into bipolar disorder evolution.

Children of parents with bipolar disorder (bipolar offspring) represent a rich cohort for study with potential for illumination of prodromal forms of bipolar disorder. Due to their high-risk nature, bipolar offspring may present phenomenological, temperamental, and biological clues to early presentations of bipolar disorder. This article reviews the evidence for establishing bipolar offspring as a high-risk cohort, the studies which point to possible prodromal states in bipolar offspring, biological findings in bipolar offspring which may be indicators of even higher risk for bipolar disorder, initial attempts at early intervention in prodromal pediatric bipolar disorder, and implications for future research.
