Is implementation science a science? Not yet.

Getting the science right for implementation is critical for making the processes for improving outcomes more predictable and effective in global public health. Unfortunately, "implementation science" has become a catchphrase for ideas, assumptions, and findings concerning the science to service gap and how to close it. The purpose of this paper is to explore the dimensions of a "science of implementation" that meets the definitions of a science and is focused on implementation variables (i.

Repeated measures of implementation variables.

It is commonly acknowledged that implementation work is long-term and contextual in nature and often takes years to accomplish. Repeated measures are needed to study the trajectory of implementation variables over time. To be useful in typical practice settings, measures that are relevant, sensitive, consequential, and practical are needed to inform planning and action.

The Teaching-Family Model: The First 50 Years.

The Teaching-Family Model was perhaps the first "evidence-based program" in human services. This article describes the development of the treatment model, the failure of the first attempts to replicate the treatment model, the discovery of larger units for replication, the modest success of first attempts to replicate larger units, and the eventual success of replications. The Teaching-Family Model is a testament to the sustainability (and continual improvement) of innovation and implementation methods and the value of the Teaching-Family Association for sustaining a community of practice and for managing the practitioner fidelity and organization fidelity data systems nationally.

Selecting an EBP to reduce long-term foster care: lessons from a university-child welfare agency partnership.

A growing implementation literature outlines broad evidence-based practice implementation principles and pitfalls. Less robust is knowledge about the real-world process by which a state or agency chooses an evidence-based practice to implement and evaluate. Using a major U.

Usability testing, initial implementation, and formative evaluation of an evidence-based intervention: lessons from a demonstration project to reduce long-term foster care.

The field of child welfare faces an undersupply of evidence-based interventions to address long-term foster care. The Permanency Innovations Initiative is a five-year federal demonstration project intended to generate evidence to reduce long stays in foster care for those youth who encounter the most substantial barriers to permanency. This article describes a systematic and staged approach to implementation and evaluation of a PII project that included usability testing as one of its key activities.

Mobilizing communities for implementing evidence-based youth violence prevention programming: a commentary.

Evidence-based programs have struggled for acceptance in human service settings. Information gleaned from these experiences indicates that implementation is the missing link in the science to service chain. The science and practice of implementation is progressing and can inform approaches to full and effective uses of youth violence prevention programs nationally.
