The Good Behavior Game (GBG), a universal classroom management intervention, has shown clear benefits in promoting the behavioral, social-emotional, and academic development of students. However, the quality with which this intervention is delivered tends to diminish over time, which decreases the likelihood of these positive outcomes. By…

The research field of multilingualism in education has grown exponentially over the last two decades, with more and more studies published every year on the need for teachers to validate the whole linguistic repertoire of their students and help them draw on their multilingualism as a resource. What has, conversely, not been accorded sufficient…

Data on implementation of school-based interventions adds highly valuable information to corresponding evaluation studies. Measuring implementation outcomes, such as fidelity or acceptability, provides information on how to improve current and future implementation processes. Moreover, analyzing intervention outcomes in combination with…

With increasing canonicity, particularly within higher education assessment, the demonstrable achievement of goals, or the delivery of a program, or as one scholar wryly deemed it, the "manipulation of the independent variable" (Moncher and Prinz 1991, p. 247), are commonly referred to as implementation fidelity or fidelity of…

Objective: The precise measurement of treatment fidelity (quantity and quality in the delivery of treatment strategies in an intervention) is essential for intervention development, evaluation, and implementation. Various informants are used in fidelity assessment (e.g., observers, practitioners [clinicians, teachers], clients), but these…

This study examined intervention fidelity (IF) and the extent to which this essential feature of response to intervention (RtI) was included within artifacts (laws and guidance documents) for states requiring RtI for specific learning disability (SLD) identification. Intervention fidelity is defined as the degree to which an intervention is…

This study investigated the effects of interdependent group contingencies (IGCs) on teacher behavior in high school classrooms. Interdependent group contingencies, rooted in the principles of applied behavior analysis, have demonstrated to be effective in managing student behaviors. However, their impact on teacher behavior has remained…

Intervention fidelity is the extent to which an individual- or systems-level student intervention is delivered comprehensively in a manner aligned with the initial plan. This first installment in a three-part series on intervention fidelity highlights the importance of ensuring classroom supports are implemented as intended and introduces…

This study explored school psychologists' practices in the areas of developing behavior intervention plans (BIPs), conducting functional behavior assessments (FBAs), and behavioral consultation. Practitioners were asked to rate their level of confidence in the implementation with fidelity of the last BIP they developed. Relationships between these…

Districts and schools are under pressure to increase student academic outcomes while meeting their various social-behavioral needs. This pressure is compounded by the responsibility of creating climates that are safe and equitable for all students where teachers can teach, and all students can learn. However, far too often, negative, and…

Positive behavior support (PBS) is an evidence-based framework for improving quality of life and preventing challenging behavior that is often implemented in combination with person-centered practices in the intellectual and developmental disability (IDD) field. Recently, state agencies and organizations supporting people with IDD have adopted a…

Treatment fidelity refers to the extent to which an intervention is implemented as planned. If researchers do not assess and report treatment fidelity, or if treatment fidelity is shown to be low, findings from intervention studies are difficult to interpret, because the intervention may not have been implemented as planned. In this article, our…

Procedural fidelity is the extent to which an intervention is implemented as designed and is an important component of research and practice. There are multiple ways to measure procedural fidelity, and few studies have explored how procedural fidelity varies based on the method of measurement. The current study compared adherence to discrete-trial…

Evidence-based programs and grassroots programs are often adapted during implementation. Adaptations are often hidden, ignored, or punished. Although some adaptations stem from lack of organizational capacity, evaluators report other adaptations happen in good faith or are efforts to better fit the local context. Program implementers, facilitators…

This dissertation examines the fidelity in which school districts are prepared to implement their reunification plan in the event of a tragedy or emergency. School emergencies continue to occur, and safety plans need to be developed and administered to support and protect students and staff. This dissertation is organized into two separate papers.…
