Delayed infant development: content analysis of a nursing diagnosis proposal

OBJECTIVE: To analyze the content of the nursing diagnosis "Delayed infant development." METHOD: Methodological study addressing the content analysis phase, using a mixed approach. The first stage was a quantitative agreement study; the second was a qualitative consensus study. Both stages were carried out with proficient individuals. For analysis, the Binomial test was used, with a p value equal to or greater than 0.05 and a cutoff point of 0.85. The level of significance adopted was 5%. RESULTS: The proposed diagnosis obtained high agreement among the judges regarding its structure (title, definition, defining characteristics, related factors, at-risk populations, and associated conditions), with more than 85% approval. Some characteristics were reformulated to align with NANDA-I, improving clarity and clinical applicability. CONCLUSION: The content validity was satisfactory, proving to be relevant, clear, and applicable to nursing practice. Its adoption may favor the early detection of delays in child development and support multidisciplinary interventions, especially in vulnerable contexts.
