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…

There is increasing evidence supporting the effectiveness of the Early Start Denver Model (ESDM) for children on the autism spectrum. However, substantial variability in response to the ESDM has been reported across participants. We examined the plausible yet untested hypothesis that variations in the fidelity level of therapists delivering the…

Purpose: Using the assessment literacy framework, the purpose of this study was to explore preservice teachers understanding and enactment of the message system during an early field experience. Method: Six PTs employed SE seasons totaling 540 min. Seven qualitative data methods were utilized. Data analysis included deductive and inductive…

We developed a six-step iterative process for developing and evaluating a model of implementation fidelity appropriate for use in an instructionally embedded assessment system. Our work explicitly connects the literature on theories of actions for assessment systems with the implementation fidelity literature originating from the program…

HealthySteps (HS) is an evidence-based integrated model designed to provide enhanced primary care services to young children and families. This article describes the strategies HS specialists use, adapt, and innovate while maintaining fidelity to the model to meet the unique needs of diverse settings, circumstances, and communities. The authors…

Premised on the idea that evaluators should be familiar with a range of approaches to program modifications, I review several existing approaches and then describe another, less well-recognized option. In this newer option, evaluators work with others to identify potentially needed adaptations for select program aspects "in advance." In…

Background: To understand and apply the results of multisite impact studies, it is necessary to know the extent to which the components of an intervention were implemented as they were designed in each context (e.g., Carroll et al., 2007; Hill, Corey, & Jacob, 2018). Rigorous and cost-effective measures of implementation fidelity can help…

This book explores the role of the teacher in dual language bilingual education (DLBE) implementation in a time of nationwide program expansion, in large part due to new and unprecedented top-down initiatives at state and district level. The book provides case studies of DLBE teachers who: (a) implemented the DLBE model with fidelity; (b)…

This study used the standard setting to establish cutscores for the fidelity of implementation of an evidence-based intervention, the Self-Determined Learning Model of Instruction (SDLMI) designed to enhance goal-directed actions in secondary students with and without disabilities. Cutscores were then applied to fidelity data from a large,…

Although our field has made significant progress in the measurement of procedural fidelity in research studies, we argue for a more nuanced and expansive perspective on procedural fidelity. Specifically, we review the status quo of procedural fidelity measurement in intervention research along with specific suggestions for increasing both…

Humans are arguably the most interesting subjects in computer vision. Modeling human 3D geometry from images captured by highly sophisticated production level cameras (10-100 cameras with precise calibration) enable a number of applications, e.g. telepresence, virtual try-on, motion analysis, etc. Despite its production level quality, the…

This study used standards setting to establish cutscores for the fidelity of implementation of an evidence-based intervention, the Self-Determined Learning Model of Instruction, designed to enhance goal-directed actions in secondary students with and without disabilities. Cutscores were then applied to a fidelity data from a large, randomized…

The PBIS Framework has demonstrated effectiveness in supporting schools in improving various prosocial outcomes including improved social, emotional, and behavioral skills; increased academic outcomes and attendance; decreased exclusionary discipline (e.g., office referrals, suspensions); and reduced reports of bullying and substance abuse. In…

Coaching is an essential component of supporting teachers to implement evidence-based practices (EBPs) in classrooms. The Self-Determined Learning Model of Instruction (SDLMI), an EBP designed to promote student self-determination, uses a research-based coaching model with six guiding principles. This qualitative study analyzed the content of…

Immersive virtual reality (VR) carries important potential, both for the creation of scientific knowledge and also for its communication. This is particularly important for studies of human spatial cognition, where psychologists now possess the power to combine the scale and fidelity of the real world with the malleability and control of the…
