Though we do our best to protect children from life's underbelly, bad things happen. Hurricanes, school shootings, divorce, exploding crime rates, economic downturns, child abuse, and acts of terror have become reality for many. Sadly, students are not immune from the chaos that often results. If a child worries that he is not safe or thinks…

Student misbehavior is a pervasive problem and may seriously affect academic achievement. Previous research hints at different effects depending on whether achievement tests or achievement judgments are used as academic outcomes. Previous research also indicates that low achievement can conversely contribute to problem behavior and that low…

The retention of "at risk" students in secondary schools is a major challenge to inclusive education policy. Students with non-compliant behaviour at this level are typically dealt with by authoritarian and punitive disciplinary systems that frequently lead to exclusion from school. This paper reports on the successful establishment of a…

The reengagement of disenchanted secondary students is one of the priorities of the educational system. Over a six-year period (2003-2004 to 2008-2009), 63 disruptive and low-performance secondary school students were integrated into a two-year garden-based learning program, which took place in southeastern Spain. This article intends to assess…

Peer victimization is a pervasive problem among children and associated with numerous psychological and behavioural problems for all participants. Research is needed to understand the complex relations between factors that increase risk of victimization and its consequences. We used autoregressive cross-lagged modelling with self-report data to…

This quasi-experimental exploratory study investigated whether a social-emotional learning program, implemented during a 1-year period, could lead to gains in social-emotional competencies and a reduction in internalizing and externalizing problems. Furthermore, it showed which pupils would benefit most from the program. The program was applied to…

In 1959, Campbell and Fiske introduced the use of multitrait-multimethod (MTMM) matrices in psychology, and for the past 4 decades confirmatory factor analysis (CFA) has commonly been used to analyze MTMM data. However, researchers do not always fit CFA models when MTMM data are available; when CFA modeling is used, multiple models are available…

This study examined the effects of out-of-school suspension on high school students. Its purpose was to determine if exclusionary discipline practices led to negative consequences such as poor academic achievement and juvenile delinquency. The study also hoped to generate new insight into current disciplinary practices in order to yield a better…

This dissertation contains two studies, which are intended to expand our current knowledge about girls with ASD without intellectual disability. The first study examined sex-differences in ASD symptom endorsement and coexisting internalizing and externalizing behaviors. The second study explored the social behaviors of boys and girls with ASD at…

The rise in the number of students found to have autism has been staggering over the past ten years. Accommodating these students effectively and appropriately in a public school is a challenge many teachers are deemed with, sometimes without adequate training. This study was aimed at affecting the underlying social misunderstandings inherent to…

This study aimed to establish potential mechanisms through which economic disadvantage contributes to the development of young children's internalizing and externalizing problems. Prospective data from fetal life to age 3 years were collected in a total of 2,169 families participating in the Generation R Study. The observed physical home…

Traumatic childhood experiences have been found to predict later internalizing problems. This prospective longitudinal study investigated whether repeated and intentional harm doing by peers (peer victimization) in childhood predicts internalizing symptoms in early adolescence. 3,692 children from the Avon Longitudinal Study of Parents and…

Impulsivity is the cardinal symptom of ADHD. It is estimated that ADHD is present in eighteen percent of children and in four percent of adults. The present study repeats and extends a previous study (Gray, Breier, Foorman, & Fletcher, 2002) that measured impulsivity in adolescents with and without ADHD, which found higher false alarm rates…

We gathered individual participant data from 16 group design studies on behavioral intervention for children with autism. In these studies, 309 children received behavioral intervention, 39 received comparison interventions, and 105 were in a control group. More children who underwent behavioral intervention achieved reliable change in IQ (29.8%)…

Jessor (2008) has recently called attention to "description" versus "explanation" in cross-cultural and cross-national comparative scholarship on adolescent development, particularly, the etiology of adolescent problem behaviors. In the current study, we were interested in testing to what extent problem behavior theory…
