Examining a developmental pathway from early behavioral inhibition to emotion regulation and social anxiety: The moderating role of parenting.

We examined the longitudinal relation between behavioral inhibition (BI) and social anxiety symptoms and behavior and the mediating role of emotion regulation (ER). Moreover, we investigated the influence of parenting behavior on the development of ER strategies. Participants were 291 children (135 male) followed longitudinally from 2 to 13 years.

Contributions of Friends' Problem Behaviors to Friendship Quality in a Sample of Children with ADHD.

Objective: It is often assumed that children with attention-deficit/hyperactivity disorder (ADHD) experience friendship difficulties because of their own problem behaviors. However, friendships are dyadic relationships between two children. This study sought to understand the incremental contributions of friends' problem behaviors to dyadic friendship quality in a clinically diagnosed sample of children with ADHD.

Infant temperament prospectively predicts general psychopathology in childhood.

Recent models of psychopathology suggest the presence of a general factor capturing the shared variance among all symptoms along with specific psychopathology factors (e.g., internalizing and externalizing).

Investigating brain electrical activity and functional connectivity in adolescents with clinically elevated levels of ADHD symptoms in alpha frequency band.

EEG measures such as power and connectivity have been widely used to investigate the neuronal underpinnings of ADHD. Traditionally, the fixed band analysis, in which a single frequency band is applied to all the subjects, has been used to estimate these EEG measures. However, there are important interindividual differences in the predominant frequency of alpha-band oscillations.

Maternal Emotion Dysregulation Predicts Emotion Socialization Practices and Adolescent Emotion Lability: Conditional Effects of Youth ADHD Symptoms.

Maternal emotional functioning and emotion socialization practices can facilitate or hinder children's emotional development, and youth with symptoms of attention-deficit/hyperactivity disorder (ADHD) are at increased risk for emotion lability. However, little is known about the independent and interactive effects of maternal emotion dysregulation and adolescent ADHD symptoms on maternal emotion socialization and adolescent emotion lability over time. Using secondary data analyses of a longitudinal community sample of youth and their mothers (N = 247; 43.

Investigation of a developmental pathway from infant anger reactivity to childhood inhibitory control and ADHD symptoms: interactive effects of early maternal caregiving.

Background: ADHD is a neurodevelopmental disorder with a complex pathogenesis. Individual differences in temperamental reactivity - in particular, anger reactivity - are predictive of ADHD. The goal of this study was to examine the moderating (maternal caregiving behaviors; MCB) and mediating (inhibitory control) variables of reactivity using a 9-year multimethod prospective longitudinal design.

Attention bias to reward predicts behavioral problems and moderates early risk to externalizing and attention problems.

The current study had three goals. First, we replicated recent evidence that suggests a concurrent relation between attention bias to reward and externalizing and attention problems at age 7. Second, we extended these findings by examining the relations between attention and behavioral measures of early exuberance (3 years), early effortful control (4 years), and concurrent effortful control (7 years), as well as later behavioral problems (9 years).

Social threat attentional bias in childhood: Relations to aggression and hostile intent attributions.

The goal of this study was to examine the ways attentional bias to social threat-measured across multiple attentional processes-is related to both child aggression and a well-established cognitive correlate of aggression (namely, hostile intent attributions). A community sample of 211 children (51% male; 9-12 years; 55% Caucasian) participated in our cross-sectional correlational design. Social threat attentional bias was measured through task performance on dot-probe, attentional shifting, and temporal order judgment tasks; each task measured different attentional processes.

Infant temperament reactivity and early maternal caregiving: independent and interactive links to later childhood attention-deficit/hyperactivity disorder symptoms.

Background: Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with origins early in life. There is growing evidence that individual differences in temperament reactivity are predictive of ADHD symptoms, yet little is known about the relations between temperament reactivity in early infancy and later ADHD symptoms or the combined effect of reactivity with early environmental factors on ADHD symptom development. Using a 9-year prospective longitudinal design, this study tested the independent and interactive contributions of infant reactivity and maternal caregiving behaviors (MCB) on parent- and teacher-reported childhood ADHD symptoms.

Behavior therapy and callous-unemotional traits: effects of a pilot study examining modified behavioral contingencies on child behavior.

The conduct problems of children with callous-unemotional (CU) traits (i.e., lack of empathy, lack of guilt/lack of caring behaviors) are particularly resistant to current behavioral interventions, and it is possible that differential sensitivities to punishment and reward may underlie this resistance.

Validation of the problem gambling severity index using confirmatory factor analysis and rasch modelling.

The Problem Gambling Severity Index (PGSI), a screening tool used to measure the severity of gambling problems in general population research, was subjected to confirmatory factor analysis and Rasch modelling to (a) confirm the one-factor structure; (b) assess how well the items measure the continuum of problem gambling severity; (c) identify sources of differential item functioning among relevant subpopulations of gamblers. Analyses were conducted on a nationally representative sample of over 25,000 gamblers compiled by merging data from the Canadian Community Health Survey and Canadian Problem Gambling Index (CPGI) integrated datasets. Results provided support for a one-factor model that was invariant across gender, age, income level, and gambler type.

The effects of instructions on mothers' ratings of attention-deficit/hyperactivity disorder symptoms in referred children.

Tested whether instructions for how to rate child attention-deficit/hyperactivity disorder (ADHD) symptoms would improve the agreement between mothers' ratings of symptoms in their children and ratings provided by teachers and objective observers. Sixty-eight mothers of 5 to 12 year old children (53 boys and 15 girls) referred for ADHD assessment were randomly assigned to receive or not receive the instructions. Mothers and teachers rated the children on the SNAP-IV Rating Scale and objective observers rated the children's behavior during structured tasks.

Replication of low-risk gambling limits using canadian provincial gambling prevalence data.

A set of low-risk gambling limits were recently produced using Canadian epidemiological data on the intensity of gambling behavior and related consequences (Currie et al. Addiction 101:570-580, 2006). The empirically derived limits (gambling no more than two to three times per month, spending no more than $501-$100o CAN per year or no more than 1% of gross income spent on gambling) accurately predicted risk of gambling-related harm after controlling for other risk factors.

A Canadian population level analysis of the roles of irrational gambling cognitions and risky gambling practices as correlates of gambling intensity and pathological gambling.

Using population data (N = 11,562) drawn from five Canadian gambling prevalence surveys conducted between 2000 and 2005, the current study investigated the relationship between irrational gambling cognitions and risky gambling practices upon (a) gambling intensity, as measured by percent of income spent on gambling and (b) tolerance, a diagnostic indicator of pathological gambling. First, we found irrational gambling cognitions and risky gambling practices to be positively related. Second, irrational gambling cognitions moderated the relationship between risky gambling practices and gambling intensity.
