Children with intellectual and developmental disabilities (IDDs) require intensive multicomponent interventions to learn to read. Parent-implemented interventions have been shown to be effective for children with disabilities and are one potential method for providing intervention. This study used a multiple probe single case design to evaluate…

To support all students, including students with disabilities, many schools have adopted a positive behavioral interventions and supports (PBIS) framework. Although rigorous research documents the beneficial effects of Tier 1 PBIS for all students and emerging research extends these findings to students with disabilities, there has not been a…

In recent years, there has been an increased research focus on developing tools to support the design, installation, and evaluation of tiered systems of support. In this special issue, we focus on research validating freely available tools to (a) measure fidelity of implementation of school-wide positive behavioral interventions and supports…

To prevent academic failure and promote long-term success, response-to-intervention (RtI) is designed to systematically increase the intensity of delivering research-based interventions. Interventions within an RtI framework must not only be effective but also be implemented with treatment fidelity and delivered with the appropriate level of…

Early intervention efforts have been effective in reducing disruptive behaviors and the probability of poor developmental outcomes. Early interventions include common practice elements to improve social functioning and decrease problem behaviors that disrupt the teaching-learning process. The First Step Next intervention has been well validated…

In this study, we assessed the feasibility and social validity of an adapted approach to positive behavior interventions and supports (PBIS) implementation in secure juvenile facilities. The authors developed a comprehensive model of facility-wide positive behavior interventions and supports (FW-PBIS) for use in secure juvenile correctional…

Fidelity of implementation of school practices is crucial to student outcomes. Several types of tools, including self-assessments, are available for measuring fidelity, but little is known regarding the relation of self-assessments of fidelity to fidelity instruments completed with the support of external experts, specifically, during the first…

There are several widely used Positive Behavioral Interventions and Supports (PBIS) implementation fidelity measures, including the Schoolwide Evaluation Tool (SET), but there is limited empirical investigation substantiating the association between specific fidelity cut point scores and student outcomes. This article examined different SET cut…

Demonstration of experimental control is considered a hallmark of high-quality single-case research design (SCRD). Studies that fail to demonstrate experimental control may not be published because researchers are unwilling to submit these papers for publication and journals are unlikely to publish negative results (i.e., the file drawer effect).…

Assessing fidelity of implementation of school-based interventions is a critical factor in successful implementation and sustainability. The Tiered Fidelity Inventory (TFI) was developed as a comprehensive measure of all three tiers of School-Wide Positive Behavioral Interventions and Supports (SWPBIS) and is intended to measure the extent to…

Despite the importance of replication for building an evidence base, there has been no formal examination to date of replication research in special education. In this review, we examined the extent and nature of replication of intervention research in special education using an "article progeny" approach and a three-pronged definition…

An antecedent exercise (AE) intervention was conducted with two young children who demonstrated challenging behaviors during a large group circle time activity in a preschool classroom; outcomes were evaluated in the context of alternating treatments designs. Results from the initial visual analysis suggested no overlap between conditions, with…

Replication research is essential to scientific knowledge. Reviews of replication studies often electronically search for "replicat*" as a textword, which does not identify studies that replicate previous research but do not self-identify as such. We examined whether the 83 intervention studies published in six non-categorical research…

Functional communication training (FCT) is a widely used and effective function-based treatment for problem behavior. The purpose of this article is to present two cases in which FCT was unsuccessful in reducing the occurrence of problem behavior displayed by two young children with an autism spectrum disorder. Both children received the same…

The present investigation examines the schoolwide applications model (SAM) as a potentially effective school reform model for increasing equity-based inclusive education practices while enhancing student reading and math achievement for all students. A 3-year quasi-experimental comparison group analysis using latent growth modeling (LGM) was used…
