Intervention development: assessing critical parameters from the intervention recipient's perspective

Before effective nursing interventions can be translated into practice, they must undergo critical examination. Although randomized controlled trials provide evidence of effectiveness, other intervention parameters require evaluation before effectiveness trials are initiated. This article describes methods for evaluating six parameters of nursing interventions (necessity, acceptability, feasibility, fidelity, safety, and effectiveness) and emphasizes the importance of assessing them from the intervention recipient's perspective.
