As evidence-based interventions are scaled, fidelity of implementation, and thus effectiveness, often wanes. Validated fidelity measures can improve researchers' ability to attribute outcomes to the intervention and help practitioners feel more confident in implementing the intervention as intended. We aim to provide a model for the validation of…

Although the field of autism intervention has strived to identify evidence-based practices, translating these interventions into real-world settings remains a significant challenge. This gap particularly impacts marginalized communities, where access to and quality of services are often inferior. Implementation science addresses these gaps by…

School psychologists have the potential to improve students' reading skills by helping schools select evidence-based programs and then supporting their implementation. Blended learning offers a flexible implementation format to address long-standing challenges implementing and scaling reading programs in schools. The purpose of this study was to…

Culturally responsive interventions for autistic children and their families have been developed and implemented to address issues related to limited representation, inequities, and disparities in access to care of minoritized families in research. Currently available reviews are relatively limited in scope or do not synthesize interventions…

As educational research increasingly emphasizes identifying effective interventions through rigorous causal methods, the role of implementation in determining a program's impact has gained renewed significance. Despite the long-standing recognition that implementation varies across contexts and influences outcomes (Berman & McLaughlin, 1974;…

Implementation fidelity is often thought of as a necessary condition to achieve internal validity and as having a relation to student outcomes. This relation is increasingly modeled; we reviewed reading intervention studies for students in pre-K-12 in which measures of implementation fidelity were included in final data analysis. A systematic…

Autistic students are educated in Australia across a variety of contexts and almost all educators use individualized goal-setting as a way of ensuring appropriate accommodations and curriculum modifications. Educators experience similar challenges when developing individualized goals for students, including lack of a standardized process for goal…

As the number of children diagnosed with autism spectrum disorder (ASD) increases, the need for well trained teachers who can implement behavior interventions also increases. The current study examines the available research to determine which methods of training are most effective in increasing teacher fidelity to implement behavior…

Background: In response to persistent challenges in early grade mathematics achievement in South Africa, two intervention projects -- Base-Ten Thinking (BTT) and the Mental Starters Assessment Project (MSAP) -- were implemented to enhance number sense through mental mathematics in Grades 2 and 3. These projects integrate Freudenthal's theory of…

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…

American Samoa, a U.S. territory, has grappled with low reading scores similar to other mainland schools. As a result, different reading interventions were implemented over the years. The problem studied was that despite using Achieve 3000 as a reading intervention for students in the local high school in American Samoa, reading scores had…

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…

Treatment fidelity is essential for predicting student outcomes and discerning between intervention ineffectiveness and invalid implementation. Despite its significance, research on treatment fidelity within Multi-Tiered Systems of Support (MTSS) and Response to Intervention (RTI) frameworks is limited. Despite their moderating role in…

Preventing young people's cigarette smoking is a major public health priority, and smoking is especially prevalent in vocational schools. Well-enforced comprehensive school tobacco policies accompanied by preventive efforts show potential to reduce smoking, but the implementation process is crucial to achieve the intended effect. We investigate…

To promote improved student outcomes, school mental health providers (SMHPs) monitor implementation fidelity when implementing evidence-based interventions. Current approaches for implementation fidelity monitoring (e.g., intervention checklists) do not account for other relevant implementation indicators best captured through qualitative data.…
