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…

Intervention scientists have used program theory-driven evaluation to design, implement, and assess the success of intervention programs for decades. However, interventions often are designed without the input of the community for which they are intended. The lack of incorporation of community members' voices that participate in various…

Evaluation practices are continuing to evolve, particularly in those areas related to formative, participatory, and improvement approaches. Improvement science is one of the evaluative practices. Its strength is that it seeks to embrace stakeholders' and frontline workers' knowledge and experience, who are often tasked with leading improvement…

Despite the increase in federal tiered evidence initiatives that require the use of rigorous evaluation designs, such as randomized experiments, there has been limited guidance in the evaluation literature on practical strategies to implement such studies successfully. This paper provides lessons learned in executing experiments in applied…

Project schedules are logic models that focus on the timing of program activities. Value derives from the fact that schedule changes are not random. Why they occur, and how long they last, can reveal information that would not be easily revealed with other approaches to evaluation. Also, using project schedules as logic models forges a strong link…

Many evaluations of programs tend to show few outcomes. One solution to this has been an increasing prominence of the movement that requires programs to implement evidence-based interventions (EBIs). But in a complex world with complex organizations and complex interventions, many challenges have arisen to the implementation of EBIs with fidelity…

In recent years, increased focus on the effectiveness and accountability of prevention and intervention programs has led to greater government funding for the implementation and spread of evidence-based health and human service delivery models. In particular, attention has been paid to programs that require significant infrastructure investment…

A theory-driven approach to evaluation (TDE) emphasizes the development and empirical testing of conceptual models to understand the processes and mechanisms through which programs achieve their intended goals. However, most reported applications of TDE are limited to large-scale experimental/quasi-experimental program evaluation designs. Very few…

The current study examines the inherent challenges of the wide-scale implementation and replication of program models. Using the Healthy Family America (HFA) program model, the study reviews the adaptation/adoption debate and highlights the ways in which program adoption and program adaptation could coexist to facilitate successful program…

Most K-12 evaluations are designed to make inferences about how a program implemented at the classroom or school level affects student learning outcomes and such inferences inherently involve hierarchical data structure. One methodological challenge for evaluators is linking program implementation factors typically measured at the classroom or…

The evaluation of an intervention delivered across multiple treatment sites presents a unique opportunity for evaluators to gauge the manner and degree to which the "impact" of treatment varies across implementation conditions and different target populations. However, the availability of implementation data for each treatment site, while…
