Longitudinal analysis of the ABCD® study Open
The Adolescent Brain Cognitive Development® (ABCD) Study provides a unique opportunity to investigate developmental processes in a large, diverse cohort of youths, aged approximately 9-10 at baseline and assessed annually for 10 years. Giv…

Callous‐unemotional traits, cognitive functioning, and externalizing problems in a propensity‐matched sample from the ABCD study Open
Background Many studies show that both callous‐unemotional (CU) traits (e.g., low empathy, lack of guilt) and cognitive difficulties increase risk for externalizing psychopathology across development. However, other work suggests that some…

Individual differences in parasympathetic functioning across social stressor tasks: Relations with child and parent anxiety Open
Children with elevated behavioural inhibition (BI) show context‐inappropriate fear and dysregulated RSA across stressor tasks. However, few studies have examined dynamic RSA within tasks and relations to parent and child anxiety. Using pie…

Unique versus shared neural correlates of externalizing psychopathology in late childhood. Open
Childhood externalizing psychopathology is heterogeneous. Symptom variability in conduct disorder (CD), oppositional defiant disorder (ODD), attention-deficit/hyperactivity disorder (ADHD), and callous-unemotional (CU) traits designate dif…

Evaluating the sensitivity to threat and affiliative reward ( <span>STAR</span> ) model in relation to the development of conduct problems and <span>callous‐unemotional</span> traits across early adolescence Open
Background The Sensitivity to Threat and Affiliative Reward (STAR) model proposes low threat sensitivity and low affiliation as risk factors for callous‐unemotional (CU) traits. Preliminary evidence for the STAR model comes from work in ea…

Parasympathetic Nervous System Functioning Moderates the Associations between Callous-Unemotional Traits and Emotion Understanding Difficulties in Late Childhood Open
Background: Callous-unemotional (CU) traits are characterized by low empathy, guilt, and prosociality, putting children at risk for lifespan antisocial behavior. Elevated CU traits have been linked separately to difficulties with emotion u…

Background Children with callous‐unemotional (CU) traits are at high lifetime risk of antisocial behavior. It is unknown if treatments for disruptive behavior disorders are as effective for children with CU traits (DBD+CU) as those without…

Contribution of risk and resilience factors to anxiety trajectories during the early stages of the COVID‐19 pandemic: A longitudinal study Open
The COVID‐19 pandemic, and the response of governments to mitigate the pandemic's spread, resulted in exceptional circumstances that comprised a major global stressor, with broad implications for mental health. We aimed to delineate anxiet…

Persistent Frustration-Induced Reconfigurations of Brain Networks Predict Individual Differences in Irritability Open
These pilot results suggest the importance of the postfrustration recovery period in the pathophysiology of irritability. Eglob in 3 specific posttask modules, involved in emotion processing, reward processing, or motor function…

Psychometric Properties, Factor Structure, and Validity of the Sensitivity to Threat and Affiliative Reward Scale in Children and Adults Open
Callous-Unemotional (CU) traits identify children at high risk of antisocial behavior. A recent theoretical model proposed that CU traits arise from low sensitivity to threat and affiliation. To assess these dimensions, we developed the pa…

Genetic versus environmental influences on callous–unemotional traits in preadolescence: The role of parenting and parental psychopathology Open
Children with callous–unemotional (CU) traits are at risk for severe conduct problems. While CU traits are moderately heritable, parenting also predicts risk. However, few studies have investigated whether parenting factors (e.g., acceptan…

Persistent frustration-induced reconfigurations of brain networks predict individual differences in irritability Open
Background Frustration, the response to blocked goal attainment, is a universal affective experience, but how the brain embodies frustration is not known. Understanding brain network dynamics during frustration may provide insight into ped…

Prospective predictors of risk and resilience trajectories during the early stages of the COVID-19 pandemic: a longitudinal study Open
Background The COVID-19 pandemic is a rapidly evolving stressor with significant mental health consequences. We aimed to delineate distinct anxiety-response trajectories during the early stages of the pandemic and to identify baseline risk…

Low social affiliation predicts increases in callous‐unemotional behaviors in early childhood Open
Background Callous‐unemotional (CU) behaviors predict risk for aggression and rule‐breaking. Low social affiliation (i.e. reduced motivation for and enjoyment of social closeness) is hypothesized to be a phenotypic marker for CU behaviors …

Across-subjects multiple baseline trial of exposure-based cognitive-behavioral therapy for severe irritability: a study protocol Open
Introduction Irritability is defined as a tendency towards anger in response to frustration. Clinically, impairing irritability is a significant public health problem. There is a need for mechanism-based psychotherapies targeting severe ir…
