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…

LifeSkills Training is the only program to prevent substance use disorder among adolescents that has evidence of effects on substance use outcomes from multiple randomized controlled trials. Evaluations have shown that the version for middle school students reduces their use of substances in high school, but these studies were conducted in the…

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…

Identification of likelihood for autism in the U.S. early intervention (EI) system facilitates referrals to diagnostic assessments and targets autism-specific needs. However, performance of autism screeners in high-likelihood preschool children and barriers to implementation need to be further studied. The current effectiveness-implementation…

Background: Comprehensive health education in schools can effectively prevent drug use and related outcomes, but successful implementation remains challenging. Contextual determinants, including intervention-setting compatibility, focus on the intervention, available resources, and leadership support, influence implementation success. This study…

Background: Implementation quality is a significant factor in determining whether a program has its intended impact (Durlak and DuPre, 2008; List et al., 2021). Therefore, when studying a program's efficacy, researchers must ensure that the program is implemented as intended to estimate its impact. To evaluate whether a program is being…

Background: Implementation of school-based health promotion programs requires contextual fit. To strengthen the nutrition education program "Krachtvoer" (ENG: "Power Food") and learn general lessons about contextual fit, this study examined how the program, the context, and program-context interactions affected teachers'…

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…

This report describes the evaluation of Lone Star AP CSP, a program developed by the National Mathematics + Science Initiative and funded by a 2019 Education Innovation and Research grant. The three-year program aimed to increase student access to and success in the Advanced Placement (AP) Computer Science Principles (CSP) course in 37 Texas high…

Response to intervention (RTI) is a valuable framework for providing effective and equitable educational opportunities to all students; however, recent research indicates that RTI programs are not achieving their potential for promoting student learning. As schools develop, implement, and sustain RTI systems, they would benefit from the addition…

The supervision of field experiences is an indispensable component of Board-Certified Behavior Analyst (BCBA®) training. During the supervised field experience, supervisors regularly provide performance feedback to trainees for the purpose of improving fidelity of implementation of various assessments and interventions. Emerging evidence supports…

The success of Positive Behavioral Interventions and Supports (PBIS) in typical schools has led to interest in PBIS for alternative programs, including residential programs. In this brief, we describe PBIS as implemented in a therapeutic treatment home for adolescents with mental health needs. The PBIS framework enabled the program to add Tier 1…

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…

In an effort to best support student learning, school districts are seeking the most effective means of improving instruction while effectively addressing student inequities. As the focus on accountability intensifies, the use of data is paramount. Access to data alone, does not ensure quality, data-driven instruction. The lack of teacher…

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…
