Women are at greater risk of exposure to interpersonal violence during pregnancy. The influence prenatal violence has on children's behavioral adjustment is generally understood to stem from its impact on mothers, but there is a dearth of prospective research to test these models. The current study evaluated the influence of interpersonal violence…

In the present investigation, we studied the development of 6 physically aggressive behaviors in infancy and toddlerhood, posing 3 questions (a) How do the prevalences of individual physically aggressive behaviors change from 8, 15, and 24 months? (b) Are there groups of children who show distinctive patterns in the way individual physically…

We tested the hypothesis that developmental precursors to aggression are apparent in infancy. Up to three informants rated 301 firstborn infants for early signs of anger, hitting and biting; 279 (93%) were assessed again as toddlers. Informants' ratings were validated by direct observation at both ages. The precursor behaviours were…

The 'terrible twos' are often associated with increased temper tantrums, noncompliance and aggression. Although some expression of these behaviors is normal, whether early individual factors can predict which children are most at risk of frequent or prolonged emotional and behavioral problems is of increasing interest. The current study of 6,067…

We contrasted Behavior Assessment System for Children, Second Edition--Parent Rating Scales--Preschool Form (BASC-2 PRS-P) parent ratings for 242 (52% African American; 39% White) preschool-aged children from three diagnostic groups: autism spectrum disorder (ASD), intellectual disability (ID), and ASD and ID (ASD/ID). Across diagnostic groups,…

We evaluated the extent to which the externalizing behavior construct is self-organizing in the first 2 years of life. Based on dynamic systems theory, we hypothesized that changes in physical aggression, defiance, activity level, and distress to limitations would each be predicted by earlier manifestations of one another. These hypotheses were…

The link between behavior problems and low academic achievement is well established, but few studies have examined longitudinal relations between early externalizing behaviors before school entry and low academic achievement following transition to formal schooling. Early inattention has been particularly overlooked, despite strong associations…

Before the 1990s, research on the early identification and prevention of severe behavior disorders (SBDs), such as aggression, self-injury, and stereotyped behavior, among young children with intellectual and developmental disabilities (IDD), was mostly done with children 3 years or older. More recent work suggests that signs of SBDs may occur as…

The LPR and STin2 polymorphisms of the serotonin transporter gene (SLC6A4) were combined into haplotypes that, together with quality of maternal parenting, were used to predict initial levels and linear change in children's (N = 138) noncompliance and aggression from age 18-54 months. Quality of mothers' parenting behavior was observed when…

Background: Children who have been exposed to intimate partner violence (IPV) experience a wide variety of short-term social adjustment and emotional difficulties, including externalizing behavioral problems such as aggression. While children are affected by IPV at all ages, little is known about the long-term consequences of IPV exposure at…

There is a very substantial literature over the past 50 years on the advantages of early detection and intervention on the cognitive, communicative, and social-emotional development of infants and toddlers at risk for developmental delay due to premature birth or social disadvantage. Most of these studies excluded children with severe delays or…

Objective: The Personal Attitude Scale (PAS; Hooley, 2000) is a method that is under development for identifying individuals high in Expressed Emotion based on personality traits of inflexibility, intolerance, and norm-forming. In the current study, the goal was to measure the association between this maternal attitudinal inflexibility, early…

Comorbid psychopathology and challenging behaviors often occur among persons with developmental disabilities. However, little attention to this issue has been reported in young children. In this study, individuals 17 through 36 months of age with varying diagnoses, such as intellectual disability, developmental delay, and Down syndrome, among…

The study adopted a person-centered approach to examine whether clusters of children could be identified on the basis of temperament profiles assessed on four occasions from infancy to early childhood, and if so whether differing temperament clusters were associated with subsequent differences in behavior problems, social skills, and school…

Investigated age differences in perceived frequency of discipline problems among preschoolers. Parent reports indicated peaks in behavior occurrences at 30-36 months for total items and 4 of 5 scales on Toddler Behavior Checklist. By 48 months, found significant decreases from peak in discipline problems only for Physical Aggression and Immaturity…
