Environmental restriction or deprivation early in development can induce social, cognitive, affective, and motor abnormalities similar to those associated with autism. Conversely, rearing animals in larger, more complex environments results in enhanced brain structure and function, including increased brain weight, dendritic branching,…

Due to the relatively late age of clinical diagnosis of autism, the early brain pathology of children with autism has remained largely unstudied. The increased use of retrospective measures such as head circumference, along with a surge of MRI studies of toddlers with autism, have opened a whole new area of research and discovery. Recent studies…

Very few existing empirical studies have explored the putative association between exposure to negative life events and psychological well-being in adults with developmental disabilities. In the present study, data on exposure to life events in the previous 12 months, adaptive behavior, problem behavior, and psychiatric problems were provided by…

The aim of this longitudinal study was to examine the associations between maternal depressive symptoms and perceptions of children's problems. One hundred and nineteen mother-child dyads were followed from the third trimester of pregnancy for almost 10 years. Depressive symptoms and background factors of the mothers and the anticipated/perceived…

The study examined the unique relationship between multiple dimensions of classroom behavioral adjustment problems and salient social-emotional competencies for urban Head Start children. These relationships were investigated using a hierarchical model that controlled for the variance in social-emotional outcomes attributed to age, gender, and…

Major physical illnesses usually have an impact on the psychological well-being of any individual. An illness of early onset, with necessity of frequent diagnostic and therapeutic interventions can adversely affect the emotional balance and behavioural adaptation of children and adolescents. This is applicable for congenital heart disease,…

This article explores psychometric characteristics of the Youth Risk Behavior Surveillance Survey (YRBS), one of the most widely used instruments to assess the prevalence of violent and other high-risk behaviors in secondary school settings. Response patterns were analyzed for a subset of 414 youths who indicated that they had carried a weapon to…

This study examined the influence of survey validity screening on the results from three group-administered school surveys administered to samples totaling approximately 5500 students in 19 schools. The estimated levels of risk behaviors, antisocial behaviors, and victim experiences were substantially reduced when respondents who gave multiple…

Oral reading fluency is defined as the combination of accuracy (i.e., words read correctly) and rate (i.e., number of words read in a specified time). One strategy that addresses oral reading fluency is repeated reading of passages. Repeated reading can improve students' reading skills by building reading fluency linked to specific performance…

The current study examined the extent to which treatment integrity was increased and maintained for 4 teachers in their regular classroom settings as a result of performance feedback and negative reinforcement. Teachers received daily written feedback about their accuracy in implementing an intervention and were able to avoid meeting with a…

Children with autism display significant learning, social and behavioural difficulties which impact on parents and teachers. Intensive child-focused behavioural interventions have proved to be an effective way of reducing these difficulties. Such programs are expensive to run and are currently not funded in New Zealand. One alternative way to…

Sure Start is a Government project that aims to prevent social exclusion by targeting children between 0 and 4 years of age living in areas of social and economic deprivation. This study examined whether a Tier 2 Behaviour Support Service within a local Sure Start project was able to bring about improvements in children's behaviour and the levels…

Four years of longitudinal data from 2,153 families with a 5th- or 6th-grade preadolescent participating in a family-focused pediatric primary-care-based prevention program were used to examine whether prevention effects were moderated by positive parenting and/or adolescent gender. Alcohol and tobacco use, internalizing problems, and…

In this article, the authors describe 12 practical strategies identified as empirically effective in preventing behavioral escalation in students: (1) Reinforce calm and on-task behaviors; (2) Know the triggers; (3) Pay attention to anything unusual about the student's behavior; (4) Do not escalate along with the student; (5) Offer students…

The present 8-year longitudinal study had two goals. The first goal was to describe different trajectories of academic functioning during the transition to high school using a group-based trajectory method. The second goal was to determine if previous family and child characteristics (notably behavioural problems and prosociality) predict these…
