The joint trajectory analysis version of Nagin's ("Group-based modeling of development." Cambridge, MA: Harvard University Press, 2005) semiparametric, group-based approach for modeling trajectories was used to assess how boy's trajectories of conduct problems (CP) and neighborhood SES covaried from ages 5 to 12. Participants were…

Addressing increasing levels of disruptive behavior and improving discipline is a national matter. The challenge is intensified by teachers' concerns about the growing inclusion of students with emotional and behavioral problems in general education classrooms and the general levels of diversity common in America's schools. Removing children with…

Young people with learning disabilities are significantly more at risk of developing mental health difficulties than their non-disabled peers, with prevalence rates of around 40% commonly reported. Nevertheless, high levels of mental health problems also exist among young people living in state care. However, few studies have examined the mental…

Background: Exposure to harsh parenting and children's skills in "Theory of Mind" (ToM) show independent and interacting associations with problem behaviors at age 2 (Hughes & Ensor, 2006). This study examined whether these age-2 measures also predict age-4 problem behaviors. Method: In a socially diverse sample (N = 120), multi-informant,…

Background: Children's early problem behavior that manifests in multiple contexts is often more serious and stable. The concurrent and predictive validity of ratings of externalizing and internalizing by four informants was examined at preschool and early school age in an at-risk sample. Methods: Two hundred forty children were assessed by mothers…

Background: Autism spectrum disorder (ASD) and fetal alcohol spectrum disorder (FASD) are both characterized by social difficulties, but overall clinical descriptions of the two disorders are different. Method: Twenty-nine children with autism and 33 children with pervasive developmental disorder-not otherwise specified (PDD-NOS) were compared to…

Background: Few longitudinal studies of child and adolescent psychopathology have examined the links between specific childhood anxiety disorders and adolescent psychiatric disorder. In this paper we test the predictive specificity of separation anxiety disorder (SAD), overanxious disorder (OAD), generalized anxiety disorder (GAD), and social…

A functional analysis showed that noncompliance occurred most often for 2 preschoolers when it resulted in termination of a preferred activity, suggesting that noncompliance was maintained by positive reinforcement. A differential reinforcement procedure, which involved contingent access to coupons that could be exchanged for uninterrupted access…

The growing interest in youth development, prevention, and assessment has challenged professional practices relative to the design, implementation, and evaluation of youth development programs. This article sheds light on the need for continuous training and staff development in the areas of program development and documentation, using the…

This study examined the social and behavioral characteristics of children with specific language impairment (SLI) as compared with a group of children with typically developing language skills (TL). The participants were 45 children (17 girls and 28 boys) with SLI and 53 children (27 girls and 26 boys) with TL. Maternal ratings of participants'…

There is increasing concern over the number of young children who exhibit challenging behaviors in early childhood settings. Comprehensive prevention models are needed to support teachers' management of challenging behaviors and to avert the development of such behaviors within at-risk populations. One approach utilizes a three-tier prevention…

This study investigated longitudinal associations between externalizing behavior and dysfunctional eating attitudes and behaviors. Participants were girls drawn from the community-based Minnesota Twin Family Study and assessed at ages 11, 14, and 17. Cross-sectional correlations indicated that the strength of the associations between externalizing…

Background: Clinical experience has proven thus far that a monodisciplinary treatment approach to behavioural and psychiatric problems in persons with intellectual disability (ID), such as psychotropic medication or behaviour modification programmes, has yielded limited success. It is clear that the complexity of behavioural and psychiatric…

Functional analysis was used to determine the possible function of inappropriate spitting behavior of an adult woman who had been diagnosed with profound mental retardation. Results of an initial descriptive assessment indicated a possible attention function and led to an attention-based intervention, which was deemed ineffective at reducing the…

Among the many methods of teaching skills to parents of disruptive children, videotape modeling of specific parent-child interaction sequences has been particularly effective. Given the likelihood of timeout resistance in defiant children, the authors tested the effectiveness of videotape parent training with a sample of clinic referred,…
