Estimates suggest that nearly 475,000 children and youth attending schools in the US are diagnosed with emotional and behaviour disorders (EBDs) such as childhood depression, dysthymia, conduct disorders, oppositional defiant disorder, attention deficit/hyperactivity disorder, selective mutism, and autism. Estimates of prevalence in Canada are…

School counselors are in a prime position to collaborate with school and community stakeholders to both prevent and respond to the challenges experienced and exhibited by students with one or more disruptive behavior disorders (DBD). In this article, the DBDs discussed include conduct disorder, oppositional defiant disorder, intermittent explosive…

This study compared in-school and out-of-school behavioral health service use and associated expenditures among children of different ages and with different psychiatric disorders. Medicaid claims from one city provided a sample of 24,271 children aged 5-17 years with psychiatric disorders who received one or more Medicaid-funded behavioral health…

The social maladjustment exclusionary clause has been a source of contention and confusion for the last 50 years. Social maladjustment has never been defined at the federal level, leaving creating the definition to local and state agencies. Social maladjusted was not included in the original definition created by Eli Bower in the 1960s. It was…

Objective: To investigate meta-analytically if the association between ADHD and illicit substance use (ISU) is maintained when controlling for conduct disorder/oppositional-defiant disorder (CD/ODD). Method: A systematic literature review was conducted through Medline from 1980 to 2008. Data extracted and selections made by one author were…

The impact of the Fast Track intervention on externalizing disorders across childhood was examined. Eight hundred-ninety-one early-starting children (69% male; 51% African American) were randomly assigned by matched sets of schools to intervention or control conditions. The 10-year intervention addressed parent behavior-management, child social…

Background: The presence of a large cavum septum pellucidum (CSP) has been previously associated with antisocial behavior/psychopathic traits in an adult community sample. Aims: The current study investigated the relationship between a large CSP and symptom severity in disruptive behavior disorders (DBD; conduct disorder and oppositional defiant…

This article will focus on a juvenile justice facility in the Netherlands, targeted at moderately intellectually disabled juveniles, who are sentenced because of serious crimes. All of the juveniles have a disruptive disorder (conduct disorder or oppositional defiant disorder) and 70% have comorbid psychiatric classifications. Treatment amounts to…

Background: Although impaired sensory processing accompanies various clinical conditions, the question of its status as an independent disorder remains open. Our goal was to delineate the comorbidity (or lack thereof) between childhood psychopathology and sensory over-responsivity (SOR) in middle childhood using phenotypic and behavior-genetic…

Given the relative lack of research on the comorbidity of anxiety disorders (ADs) and conduct problems (oppositional defiant disorder, conduct disorder) in youth, we examine this comorbidity from both basic and applied perspectives. First, we review the concept of comorbidity and provide a framework for understanding issues pertaining to…

Background: It is increasingly recognized that youth who follow early onset persistent (EOP), childhood limited (CL) and adolescent onset (AO) trajectories of conduct problems show somewhat varying patterns of risk (in childhood) and adjustment problems (in adolescence and adulthood). Little, however, is known about how other adjustment problems…

Background: Childhood behavioral disorders including conduct disorder (CD), oppositional defiant disorder (ODD), and attention-deficit/hyperactivity disorder (ADHD) often co-occur. Prior twin research shows that common sets of genetic and environmental factors are associated with these various disorders and they form a latent factor called…

Background: We examined racial/ethnic disparities in school-based behavioral health service use for children with psychiatric disorders. Methods: Medicaid claims data were used to compare the behavioral healthcare service use of 23,601 children aged 5-17 years by psychiatric disorder (autism, attention deficit hyperactivity disorder [ADHD],…

Behavioral genetic research has concluded that the more important environmental influences result in differences between siblings (referred to as "nonshared"; "e[superscript 2]"), whereas environmental influences that create similarities between siblings (referred to as "shared"; "c[superscript 2]") are indistinguishable from zero. However, there…

In typically developing children, boys are more commonly diagnosed than girls with disruptive behavior disorders, namely, attention-deficit/hyperactivity disorder, conduct disorder, and oppositional defiant disorder. For children with intellectual disability (ID), the evidence for this gender effect is less clear. In this report we examine gender…
