Treatment fidelity in nursing education research: Striking a balance between rigor and real-world relevance as a contemporary challenge

Background: Treatment fidelity is widely recognized as a cornerstone of essential rigor in nursing research and is frequently emphasized in education. However, curricula often do not address the practical challenges that occur when applying treatment fidelity in studies involving complex interventions or those requiring contextual adaptations. Contemporary issue: When students are taught to equate rigor with uniformity, treatment fidelity becomes separated from the contextual and relational realities of care. In this paper, we examine how treatment fidelity can be taught in ways that align with current understandings of complexity and person-centered practice. Discussion: Recent literature and empirical examples from transitional care, long-term care, and digital health interventions indicate that treatment fidelity is best understood as a dynamic, context-responsive process. We propose a pedagogical reframing that positions treatment fidelity as a tool to support contextual sensitivity, ethical judgment, and innovative application, rather than solely enforcing rigid standardization. Conclusions: Reconceptualizing treatment fidelity allows nursing education to prepare researchers who balance consistency with meaningful adaptation. From this perspective, treatment fidelity is understood not only as a procedural requirement but also as an interpretive framework, which increases rigor while remaining responsive to real-world conditions.
