Intervention Fidelity- The key to research validity

Sandra L Siedlecki

Overview

Intervention fidelity refers to the standardization of a research intervention. If the intervention is delivered differently to different people, then the results of the study will be impacted, and thus cannot be trusted. This article points out the basic guidelines the researcher needs to follow for any intervention study.

Summary

Intervention fidelity impacts the validity of your research findings. The better you are able to control for even small variations in the delivery of the intervention, the more likely it is that you can trust your findings.

As a reviewer of many research proposals and many research manuscripts, one limitation to intervention study stands out; that the lack of attention provided by the researcher to assuring that the intervention is delivered the same way each time. I hope this short article will offer concrete and practical suggestions that can be easily followed to enhance the rigor of any intervention study,Dr. Sandra L Siedlecki, PhD, RN, APRN-CNS
