Article
Full-text available
Objective: To examine the conceptualizations held by psychiatrists and psychologists around the world of the relationships among mental disorders in order to inform decisions about the structure of the classification of mental and behavioral disorders in World Health Organization's International Classification of Diseases and Related Health Problem...
Article
Full-text available
This study examined psychologists' views and practices regarding diagnostic classification systems for mental and behavioral disorders so as to inform the development of the ICD-11 by the World Health Organization (WHO). WHO and the International Union of Psychological Science (IUPsyS) conducted a multilingual survey of 2155 psychologists from 23 c...
Article
Full-text available
Background. There is substantial evidence to suggest that aggressive behavior is associated with poor academic performance in school-aged children. However, less is known about how different subtypes of aggression are related to academic performance and what variables may account for this association. Objective. The current study examined unique as...
Article
Relations between symptoms of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) and bullying-victimization in adolescence are not yet clear. Accordingly, the current study evaluated these associations, with attention to gender differences, in a sample of predominantly Latino 9th-12th grade students (52.6 % male...
Article
Oppositional defiant disorder (ODD) is a valid mental health disorder, characterized by negativistic defiant behavior and angry, irritable mood. The very low and stable prevalence rate over development from early childhood into adulthood suggests that ODD does not erroneously medicalize normative childhood behavior. ODD is associated with significa...
Article
Full-text available
Irritability is often described as a common problem affecting youth referred for mental health services; however, little is known about the prevalence and nature of irritability as a focus of treatment. We examined assessment data from a diverse sample of youths (N = 206; ages 7–15; 52% male, 48% female; 33% White, 27% Black, 25% Latinx) referred f...
Article
Objective Discrepancies between caregiver and youth reports of emotional and behavioral symptoms are well-documented, with cross-informant correlations often falling in the low to moderate range. Studies have shown that caregiver-youth (dis)agreement in reporting of youth symptoms is related to treatment outcomes. However, commonly used methods for...
Article
Background The diagnosis of paraphilic disorder is a complicated clinical judgment based on the integration of information from multiple dimensions to arrive at a categorical (present/absent) conclusion. The recent update of the guidelines for paraphilic disorders in ICD-11 presents an opportunity to investigate how mental health professionals use...
Article
Severe irritability is common in treatment-referred youth, often occurring in externalizing, anxiety, and mood conditions. The best available evidence indicates behavioral parent training and cognitive-behavioral therapy as first-line interventions. Modular approaches (eg, MATCH) can package these strategies in a flexible format, facilitating perso...
Article
Full-text available
Background: Severe irritability is a common, impairing problem among youth referred for mental health services, but evidence to guide care is limited. Treatment research can be advanced by adopting a transdiagnostic perspective, leveraging existing evidence-based treatment (EBT) techniques, and situating irritability within the context of emotion d...
Article
Full-text available
Introduction: Schools have become a primary setting for providing mental health care to youths in the U.S. School-based interventions have proliferated, but their effects on mental health and academic outcomes remain understudied. In this study we will implement and evaluate the effects of a flexible multidiagnostic treatment called Modular Approac...
Article
Objective One strategy for improving the clinical utility of mental health diagnostic systems is to better align them with how clinicians conceptualize psychopathology in practice. This approach was used in International Classification of Diseases 11th Revision (ICD‐11) development, but its underlying assumption—a link between taxonomic “fit” and c...
Article
Full-text available
It has often been suggested that the field would benefit from a single, unified classification of mental disorders, although the priorities and constituencies of the two sponsoring organizations are quite different. During the development of the ICD-11 and DSM-5, the World Health Organization (WHO) and the APA made efforts toward harmonizing the tw...
Article
Objective: Implementation of evidence-based treatments in funded trials is often supported by expert case consultation for clinicians; this may be financially and logistically difficult in clinical practice. Might less costly implementation support produce acceptable treatment fidelity and clinical outcomes? Method: To find out, we trained 42 co...
Article
Background: Research on youth irritability has proliferated in recent years, largely facilitated by items from existing measures and by key new instruments like the Affective Reactivity Index (ARI). The present study extends this literature by investigating the psychometric properties of the parent- and youth-report ARI and the correlates of irrita...
Article
Full-text available
This study used an accelerated longitudinal design to investigate trajectories of proactive and reactive aggression in middle childhood and their outcomes in early adolescence. Children (N = 1420; ages 5-12; 48% female) were assessed biannually over 6 school years. Classroom teachers rated students' proactive and reactive aggression throughout grad...
Article
Full-text available
Background: Severe irritability has become an important topic in child and adolescent mental health. Based on the available evidence and on public health considerations, WHO classified chronic irritability within oppositional defiant disorder (ODD) in ICD‐11, a solution markedly different from DSM‐5’s (i.e. the new childhood mood diagnosis, disrup...
Article
Full-text available
Objective: To examine the preliminary effectiveness of a modular, transdiagnostic, behavioral/cognitive-behavioral intervention (MATCH) compared with standard manualized treatments (SMT) and usual care (UC) for treating youth with severe irritability. Method: We analyzed data from an effectiveness trial in which treatment-referred youths (N = 174;...
Article
A critical task in psychotherapy research is identifying the conditions within which treatment benefits can be replicated and outside of which those benefits are reduced. We tested the robustness of beneficial effects found in two previous trials of the modular Child STEPs treatment program for youth anxiety, depression, trauma, and conduct problem...
Article
Full-text available
The goal of this article is to investigate the symptom dimensions of oppositional defiant disorder (ODD; irritability, defiance) and attention deficit/hyperactivity disorder (ADHD; inattention, hyperactivity-impulsivity) as predictors of academic performance, depressive symptoms, and peer functioning in middle childhood. Children (N = 346; 51% fema...
Article
Full-text available
Research suggests that irritability and defiance are distinct dimensions of youth oppositionality that are differentially associated with internalizing and conduct problems, respectively. Because much of this evidence has emerged with limited psychometric evaluation, we conducted the first multi-informant examination of selected Child Behavior Chec...
Article
Full-text available
Background: The World Health Organization (WHO) International Classification of Diseases and Related Health Problems (ICD) is used globally by 194 WHO member nations. It is used for assigning clinical diagnoses, providing the framework for reporting public health data, and to inform the organization and reimbursement of health services. Guided by o...
Article
Severe irritability is a common and clinically important problem longitudinally associated with internalizing and externalizing problems in children. To better understand these mechanisms and to inform treatment research, we tested cognitive-behavioral processes as candidate mediators in the paths from irritability to later problems. Methods: A sch...
Article
An emerging trend in youth psychotherapy is measurement-based care (MBC): treatment guided by frequent measurement of client response, with ongoing feedback to the treating clinician. MBC is especially needed for treatment that addresses internalizing and externalizing problems, which are common among treatment-seeking youths. A very brief measure...
Article
Full-text available
Evidence supports the distinctions between forms (relational vs. physical) and functions (proactive vs. reactive) of aggression; however, little research has investigated these two subtype frameworks simultaneously or by teacher-report in early childhood. We examined the factor structures, interrelations, and longitudinal associations of teacher-re...
Article
Child internalizing and externalizing problems have been identified as high priority intervention targets by the World Health Organization. Parental depression is a risk factor for development of these childhood problems and may negatively influence intervention outcomes; however, studies have rarely assessed its influence on these outcomes. The pr...
Article
The failure model posits that peer rejection and poor academic performance are dual pathways in the association between early aggressive behavior and subsequent depressive symptoms. We examined this model using an accelerated longitudinal design while also incorporating proactive and reactive aggression and gender moderation. Children in 1st, 3rd,...
Article
Full-text available
Autism spectrum disorder (ASD) is diagnosed more often in boys than in girls; however, little is known about the nature of this sex/gender discrepancy or how it relates to diagnostic assessment practices. This study examined the performance of the Social Communication Questionnaire (SCQ) in screening for ASD among boys and girls. Data were drawn fr...

Full-text available
Background A link between aggression and disciplinary actions has been established; however, specific associations between reactive and proactive functions of aggression and disciplinary actions in the elementary school setting have not been evaluated. A better understanding of links between functions of aggression and disciplinary actions could di...
Chapter
This chapter provides an overview of extant literature supporting the influence (direct, indirect, and interactive effects) of school and neighborhood factors on oppositional defiant disorder (ODD) and conduct disorder (CD) symptomatology. Simply by virtue of the sheer amount of time youth spend at school, the school context will have direct influe...

Article
Full-text available
Previous research has demonstrated that symptoms of attention-deficit/hyperactivity disorder (ADHD) are associated with higher levels of victimization, but little is known about protective factors. The purpose of the study was to examine whether physical activity attenuated the associations among ADHD symptoms and physical and relational victimizat...
Article
Full-text available
Previous research suggests that the symptoms of oppositional defiant disorder (ODD) reflect both a general diagnostic construct and two distinct symptom dimensions, irritability and defiant behavior. Recent studies have found that these two symptom dimensions exhibit different patterns of correlates and outcomes (e.g., irritability linked to depres...
Article
Evidence-based practice (EBP) has become a central focus in clinical child and adolescent psychology. As originally defined, EBP in psychology is the integration of the best available research evidence, patient characteristics, and clinical expertise. Although evidence-based perspectives have garnered widespread acceptance in recent years, there ha...
Article
Previous research shows that parent psychological control and child emotion dysregulation are both associated with the development of aggression in children. This longitudinal study sought to clarify these relations by examining emotion dysregulation as a moderator of the associations between psychological control and relational and physical aggres...
