While significant heritability for childhood aggression has been claimed, it is not known whether there are differential genetic and environmental contributions to proactive and reactive forms of aggression in children. This study quantifies genetic and environmental contributions to these two forms of aggression in an ethnically diverse urban…

Background: Autism spectrum disorder (ASD) includes symptoms that vary in severity and frequency between children. Consequently, multiple psychometric assessment procedures are recommended to detect an ASD, including scales which asses the presence and nature of ASD-related behaviour. However, to date, few studies have examined the relative and…

The present study examined the emergence of flattery behavior in young children and factors that might affect whether and how it is displayed. Preschool children between the ages of 3 and 6 years were asked to rate drawings produced by either a present or absent adult stranger (Experiments 1 and 2), child stranger (Experiments 2 and 3), classmate,…

Formal programs covering the time young people are not in school (only 20 percent of the time) have burgeoned rapidly in the past few decades as a result of profound societal changes. Although the need of all children for out-of-school-time programs has not been met, millions of youngsters do participate in out-of-school-time programs sponsored by…

To investigate dropout from parenting programs for disruptive behavior disorders, we followed 18 clients prospectively from the beginning of a manualized treatment program to three month follow-up. Using qualitative and quantitative methods, we then compared those who dropped out of the program with those who completed it. We found that in…

There is a void in the literature with regard to Hispanic parents' views about common interventions for children with behavior problems. The purpose of this study was to examine the treatment acceptability of child management techniques in a Mexican American sample. Parents' acculturation was also examined to determine if it would account for…

Genetically informative data can be used to address fundamental questions concerning the measurement of behavior in children. The authors illustrate this with longitudinal multiple-rater data on internalizing problems in twins. Valid information on the behavior of a child is obtained for behavior that multiple raters agree upon and for…

We examined the role of the teacher-child relationship quality (close, dependent, and conflictive) on preschoolers' (N=95) academic readiness for kindergarten, and we tested children's prosocial and aggressive behavior and peer group exclusion as mediators of this relation. A unique feature of this study is the ethnically and socio-economically…

To assess the degree to which a mand repertoire that was taught to children with autism would generalize from adults to peers, three preschool-aged children diagnosed with Autism were first taught to mand with adult instructors, and then were tested for generalization across three subsequent phases that involved parents, siblings, and peers.…

A growing body of evidence indicates that for some children, early incidences of challenging behaviors are predictors of later difficulties. These incidences of challenging behaviors may predict mental health issues, social adjustment issues and/or increased challenging behaviors that will impede school success and impact transition to adult life…

This dissertation describes how the medical categories of Attention Deficit Disorder (ADD) and Reading Disability (RD) have become commonsense ways to understand educational problems. I explore historical precursors of ADD and RD followed by a report on fieldwork I conducted in a first grade classroom of mostly Latino and low-income children. I…

Researching the epidemiology and estimating the prevalence of fetal alcohol syndrome (FAS) and other fetal alcohol spectrum disorders (FASD) for mainstream populations anywhere in the world has presented a challenge to researchers. Three major approaches have been used in the past: surveillance and record review systems, clinic-based studies, and…

Background: Previous research has reported on the effectiveness of the Signposts program for supporting families of children with an intellectual disability and difficult behaviour (Hudson et al., 2003; Hudson, Cameron, & Matthews, 2008). This paper reports on an investigation of the extent to which child characteristics moderate the…

School-based approaches to addressing aggression in the early grades have focused on explicit curriculum addressing social and emotional processes. The current study reviews research on the distinct modes of aggression, the status of current research on social and emotional processing relevant to problems of aggression amongst young children, as…

Research examining the influence of social relationships on child outcomes has seldom examined how individuals derive social capital from more than one context and the extent to which they may benefit from the capital derived from each. We address this deficit through a study of child behavior problems. We hypothesize that children derive social…
