Gender differences have been found in post-school outcomes of students with disabilities, yet these differences are rarely examined. To determine whether male and female high school students with disabilities scored differently in non-academic behaviors known to affect post-school education and employment measured by the Transition Assessment and…

Cluster randomized experiments are now widely used to examine intervention effects in prevention science. It is meaningful to use empirical benchmarks for interpreting effect size in prevention science. The effect size (i.e., the standardized mean difference, calculated by the difference of the means between the treatment and control groups,…

Previous research suggests that Positive Behavioral Interventions and Supports (PBIS) can reduce student disciplinary office referrals and out-of-school suspensions, especially when implemented with fidelity. Existing research is mixed as to whether PBIS also contributes to improvements in student achievement, but at least one study has found that…

This study evaluated the long-term impact of schoolwide positive behavioural interventions and supports (PBIS) on student academic achievement. In this quasi-experimental study, academic achievement data were collected over 9 years. The 21 elementary, middle, and high schools that achieved moderate to high fidelity to the Save & Civil Schools'…

Acting out behaviors is a hindrance to learning across the country. The school-wide positive behavior support (SWPBS) model is a behaviorally-based systems approach to addressing problem behaviors in our school today. The problem this study is designed to address is the issue that student misbehaviors and disruptions cause a loss of valuable…

The purpose of this study was to examine the extent to which distinct patterns of fidelity of implementation emerged for 5,331 schools over a five-year course of implementing school-wide positive behavioral interventions and supports (SWPBIS). We used latent class analysis to classify schools based on their likelihood of implementing SWPBIS with…

There is growing interest in the use of a multi-tiered system of supports framework to address issues related to school climate and bullying. Positive Behavioral Interventions and Supports (PBIS) is one such model that has received considerable attention; however, nearly all of the extant literature has focused on elementary and middle schools,…

We conducted a potential efficacy trial examining the effects of classroom-wide implementation of the "Pyramid Model for Promoting Young Children's Social-Emotional Competence" on teachers' implementation of "Pyramid Model" practices and children's social-emotional skills and challenging behavior. Participants were 40 preschool…
