AI Article Synopsis
- The study explores the trait-impulsivity hypothesis, suggesting that impulsivity is fundamental to the symptoms of ADHD and ODD.
- Researchers used network analysis to examine how different aspects of ADHD (inattention and hyperactivity/impulsivity) and ODD (anger, vindictiveness, defiance) relate to various components of impulsivity measured by the UPPS-P model.
- Results indicated that ADHD and ODD dimensions have unique associations with different types of impulsivity, adding new insights to current theories on impulsivity in these disorders.
Article Abstract
Background: The trait-impulsivity hypothesis posits impulsivity as the underlying substrate of Attention-deficit/hyperactivity disorder (ADHD) and Oppositional defiant disorder (ODD) symptom expressions. The current study applied network analysis to evaluate the inter-relationships of dimensions within ADHD (inattention and hyperactivity/impulsivity) and ODD (anger/irritable, vindictiveness, and argumentative/defiant behavior) with components of impulsivity as captured by the UPPS-P model (negative urgency, lack of premeditation, lack of perseverance, sensation seeking, and positive urgency).
Method: A total of 324 emerging adults (women = 246) from the general community completed questionnaires covering these dimensions.
Results: Our findings showed that the ADHD and ODD dimensions were associated differentially with different types of impulsivity, in their unique patterns of network connectivities, a possibility that has had little attention in the trait-impulsivity hypothesis literature.
Conclusions: This study is the first to tease out the unique associations of the ADHD and ODD dimensions with different types of impulsivity, and in that way provide new contributions to our understanding of the existing trait impulsivity theory. Our findings would be especially relevant to those interested in understanding how different dimensions of trait impulsivity underly the ADHD and ODD dimensions.

Importance: The pathophysiology of ADHD is complicated by high rates of psychiatric comorbidities, thus delineating unique versus shared functional brain perturbations is critical in elucidating illness pathophysiology.
Objective: To investigate resting-state fMRI (rsfMRI)-complexity alterations among children with ADHD, oppositional defiant disorder (ODD), and obsessive-compulsive disorder (OCD), respectively, and comorbid ADHD, ODD, and OCD, within the cool and hot executive function (EF) networks.
Design: We leveraged baseline data (wave 0) from the Adolescent Brain and Cognitive Development (ABCD) Study.
Functional and structural connectivity of the subregions of the amygdala in ADHD children with or without ODD.

Objectives: The current study aimed to investigate the structural and functional connectivity of the subregions of the amygdala in children with Attention Deficit/Hyperactivity Disorder (ADHD) only or comorbid with Oppositional Defiant Disorder (ODD).
Methods: A total of 354 children with ADHD-only, 161 children with ADHD and ODD (ADHD + ODD), and 100 healthy controls were enrolled. The Child Behavior Checklist (CBCL) and the Behavior Rating Inventory of Executive Function (BRIEF) were filled out by caregivers.
Self-Rated Symptoms of Oppositional Defiant Disorder and Conduct Disorder: Factor Structure, Reliability, and Validity in a Clinical Sample of Adolescents.

This study examined the psychometric properties of self-rated symptoms of oppositional defiant disorder (ODD) and conduct disorder (CD). We analyzed symptom ratings from a clinical outpatient sample of 658 adolescents aged 11;0-17;11 years diagnosed with ODD/CD and/or attention-deficit hyperactivity disorder. In two steps, we examined the factor structure of ODD models and an additional CD symptom dimension using confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM).

Childhood conditions of inattention and disruptive behavior, such as Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD), are prevalent but undertreated worldwide. One promising solution is harnessing digital technology to enhance school clinician training and ADHD/ODD intervention programs. We conducted a school-clustered randomized controlled trial of CLS-R-FUERTE: a program featuring training/consultation for school clinicians to deliver a six-week intervention comprised of weekly parent and student skills groups, as well as support teachers' classroom management in the form of a Daily Report Card, all facilitated by electronic program manuals/materials and videoconferencing.

Background: Behavioral parent training (BPT) is a well-established intervention for children with attention-deficit/hyperactivity disorder (ADHD), but most programs are long, which may limit their accessibility. This could be improved by making programs shorter. Here, we studied (1) the feasibility of a new brief BPT program and its procedures, and (2) pre-post changes in daily rated problem behaviors (primary outcome), children's disruptive behaviors, ADHD/ODD characteristics, impairment, and parents' sense of parenting competence (secondary outcomes).
