The purpose of this study was to identify the most important perceived enablers and barriers regarding sustainability of school-wide positive behavioral interventions and supports. School personnel representing 860 schools implementing or preparing to implement school-wide positive behavioral interventions and supports completed an open-ended survey of factors regarding its sustainability. Qualitative analyses were used to assess perceptions of the most important factors related to sustainability. Thematic analysis produced 13 themes regarding enablers and/or barriers. The most commonly cited enablers were staff buy-in, school administrator support, and consistency. The most commonly cited barriers were staff buy-in, resources: time, and resources: money. Results are discussed in terms of enhancing durability of evidence-based practices in schools.
Multiple baseline designs—both concurrent and nonconcurrent—are the predominant experimental design in modern applied behavior analytic research and are increasingly employed in other disciplines. In the past, there was significant controversy regarding the relative rigor of concurrent and nonconcurrent multiple baseline designs. The consensus in recent textbooks and methodological papers is that nonconcurrent designs are less rigorous than concurrent designs because of their presumed limited ability to address the threat of coincidental events (i.e., history). This skepticism of nonconcurrent designs stems from an emphasis on the importance of across-tier comparisons and relatively low importance placed on replicated within-tier comparisons for addressing threats to internal validity and establishing experimental control. In this article, we argue that the primary reliance on across-tier comparisons and the resulting deprecation of nonconcurrent designs are not well-justified. In this article, we first define multiple baseline designs, describe common threats to internal validity, and delineate the two bases for controlling these threats. Second, we briefly summarize historical methodological writing and current textbook treatment of these designs. Third, we explore how concurrent and nonconcurrent multiple baselines address each of the main threats to internal validity. Finally, we make recommendations for more rigorous use, reporting, and evaluation of multiple baseline designs.
The success of function-based interventions depends not just on the quality of procedures but also on the extent to which procedures are implemented as planned. Too often in schools, effort is committed to functional assessment and behavior support plan design, only to be followed by weak implementation. This study used a multiple baseline across participants design to examine whether a functional relation exists between a treatment package consisting of (a) self-monitoring treatment fidelity, (b) collecting data on student behavior, (c) entering fidelity and student behavior data into an online data management application, and (d) reviewing those data weekly using graphs generated by the application. Results indicate improved treatment fidelity and student behavior were associated with the treatment package. Potential contributions are discussed in terms of establishing efficient systems for schools that provide the structure for effective implementation of function-based interventions.
The use of restraint and seclusion in schools has been identified repeatedly as an approach that is overused, misused, and potentially dangerous. In this article, we emphasize the importance of an approach to supporting students with significant problem behavior that focuses on prevention, evidence-based intervention procedures, heightened levels of monitoring, and documented professional development. While the need for the use of restraint in emergency conditions will remain, the overall rate at which restraint and seclusion are used needs to be reduced and the quality of support for students with significant problem behavior needs to improve. An example of one district that is adopting a comprehensive alternative approach is provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
