Methodological quality, study designs, and epistemological precision in scientific production in nursing

Abstract

Scientific excellence in nursing does not depend solely on the social relevance of the topic under investigation, the timeliness of the problem, or the sophistication of the analytical techniques employed. It depends, above all, on the coherence among the research question, the epistemological framework, the methodological design, the analytical procedures, and the strength of the conclusions presented. This coherence constitutes one of the core elements of methodological quality. When it is weak, a study may appear formally well structured but produce inferences that are imprecise, overstated, or incompatible with its own investigative architecture.
