Temperament and externalizing problems are closely linked, but research on how they codevelop across adolescence remains sparse and equivocal. Reinforcement sensitivity theory (RST) provides a useful framework for understanding temperament and externalizing problems associations. During adolescence, oppositional problems are posited to be linked…

Recent work indicates clinically meaningful differences in domains of psychopathic personality -- such as grandiose-manipulative (GM), callous-unemotional (CU), and daring-impulsive (DI) traits -- and parenting factors. Yet, different domains of parenting and reports from multiple informants may vary in their associations to psychopathic traits.…

Extended school non-attendance, commonly named truancy or school refusal, has over the last decade attracted attention among educational researchers. This article points to a need for theoretical perspectives that can account for the complexity and ambiguity of the phenomenon. The article presents a critical analysis of the research field of…

Objective: Pathological exercise is a dangerous behavior often observed in eating disorders. Data investigating associated characteristics of pathological exercise in men are lacking, despite college men and women being at equally elevated risk for developing eating disorders. Participants: Two hundred and twenty-four college men who exercise…

Inhibition (a temperamental profile characterized by elevated levels of avoidance behaviors) is associated with increased likelihood for developing anxiety and depression, whereas exuberance (a temperamental profile characterized by elevated levels of approach behaviors) is associated with increased likelihood for developing externalizing…

Background: Studies suggest that prosocial behavior, having high empathy and engaging in behaviors intended to benefit others, may predict mental health or vice versa; however, these findings have been mixed. The purpose of the current study was to examine the bidirectional relationships between prosocial behavior and dimensions of psychopathology…

Frontal asymmetry (FA), the difference in brain activity between the left versus right frontal areas, is thought to reflect approach versus avoidance motivation. This study (2012-2021) used functional near-infrared spectroscopy to investigate if infant (M[subscript age] = 7.63 months; N = 90; n = 48 male; n = 75 White) FA in the dorsolateral…

Delay of gratification tasks have an impressive predictive value for various outcomes and are designed to measure self-regulation. Since many behavioural and psychological conditions in children are related to limitations in self-regulation, the extent to which delay tasks can be used as a screening for the detection of psychopathology is…

Objective: We employed latent profile analysis (LPA) to discern configurations of executive functioning (EF) and neuroticism (NE) and tested their concurrent validity with respect to internalizing and externalizing problems and physical health. Participants: A total of 125 college students completed the study. Methods: Participants self-reported…

The Nisonger Child Behavior Rating Form (NCBRF) was developed to specifically screen psychopathology and problem behavior in children and adolescents with IDD. This study aimed to update the NCBRF to the "Diagnostic and Statistical Manual of Mental Disorders, 5th Edition" (DSM-5) and screen for the most prevalent psychopathologies that…

This study is a secondary data analysis that extends knowledge about the effects of the early childhood Family Check-Up (FCU) intervention to trajectories of general psychopathology problems (p factor) across early and middle childhood, and effects on adolescent psychopathology and polydrug use. The Early Steps Multisite study (ClinicalTrials.gov…

Background: International literature has underlined the complex interplay between genetic and environmental variables in shaping children's emotional-behavioral functioning. Objective: This study aimed to explore the dynamic relationship between children's Dopamine Transporter (DAT1) genotype and methylation, and maternal and paternal affective…

Early preventive interventions can improve outcomes in childhood, but the most effective interventions can continue to deliver benefits through the life course. The Fast Track intervention, a randomized controlled trial for children at risk of conduct problems, has lowered psychopathology, substance use problems, and criminality and elevated…

This study investigated the relationship between mathematics difficulties and psychopathology in a large community sample (N = 881) of youth (8-18 years of age) in the United States. The primary aims of the study were to (a) test the associations between mathematics difficulties and specific components of internalizing, externalizing, attention,…

Frequency of feeding problems, gastrointestinal (GI) symptoms, challenging behavior, sensory problems and comorbid psychopathology were assessed using the following questionnaires: Screening Tool for Feeding Problems for Children, GI Symptoms Inventory, Behavior Problems Inventory Short Form, Short Sensory Profile, and Autism Spectrum…
