Background. “Fidelity” an intrinsic property of simulation is crucial to simulation design and educational effectiveness. Yet the term fidelity is inconsistently used, which makes it difficult to draw inferences from current literature and translate research to practice. Aim. In this article, we attempt to bring some clarity to the term simulation fidelity in healthcare education. Method. We ar...

High-fidelity patient simulation is a method of education increasingly utilised by educators of nursing to provide authentic learning experiences. Fidelity and authenticity, however, are not conceptually equivalent. Whilst fidelity is important when striving to replicate a life experience such as clinical practice, authenticity can be produced with low fidelity. A challenge for educators of und...

BACKGROUND Prior studies measuring fidelity of complex interventions have mainly evaluated adherence, and not taken factors affecting adherence into consideration. A need for studies that clarify the concept of fidelity and the function of factors moderating fidelity has been emphasized. The aim of the study was to systematically evaluate implementation fidelity and possible factors influencing...

High rates of error-prone replication result in the rapid accumulation of genetic diversity of RNA viruses. Recent studies suggest that mutation rates are selected for optimal viral fitness and that modest variations in replicase fidelity may be associated with viral attenuation. Arthropod-borne viruses (arboviruses) are unique in their requirement for host cycling and may necessitate substanti...

The main aim of this study was to test whether the effectiveness of a worksite physical activity intervention delivered in five work organizations varied as a function of intervention fidelity. We conducted a fidelity analysis as part of a large matched-pair cluster randomized controlled trial of a worksite physical activity intervention (AME for Activity). Participants (N = 1260) were employee...

To help inform drug abuse prevention research in school settings about the issues surrounding implementation, we conducted a review of the fidelity of implementation research literature spanning a 25-year period. Fidelity has been measured in five ways: (1) adherence, (2) dose, (3) quality of program delivery, (4) participant responsiveness and (5) program differentiation. Definitions and measu...

Intrahost genetic diversity and replication error rates are intricately linked to RNA virus pathogenesis, with alterations in viral polymerase fidelity typically leading to attenuation during infections in vivo. We have previously shown that norovirus intrahost genetic diversity also influences viral pathogenesis using the murine norovirus model, as increasing viral mutation frequency using a m...

We study quantum fidelity, the overlap between two ground states of a many-body system, focusing on the thermodynamic regime. We show how a drop in fidelity near a critical point encodes universal information about a quantum phase transition. Our general scaling results are illustrated in the quantum Ising chain for which a remarkably simple expression for fidelity is found.
