ICNP® subset for breastfeeding: validity of operational definitions, diagnoses, outcomes and interventions

Abstract

Objective: To describe the construction and content validity of operational definitions and statements of nursing diagnoses, outcomes and interventions contained in an ICNP® subset for woman, child and family care in the breastfeeding process. Methods: This is a methodological study carried out in two stages: construction of operational definitions, diagnoses and nursing interventions for assistance in the breastfeeding process; validity with 37 judges, selected by snowball sampling and through a search on the Plataforma Lattes, who assessed 58 operational definitions, 8 nursing diagnoses/outcomes and 29 nursing interventions. The Concordance Index was used for data analysis. Results: Only four statements of nursing diagnoses and five interventions of the subset in question are contained in the latest version of ICNP®. Of the 58 operational definitions, 54 were validated (93.1%), 39 with a Concordance Index ≥0.8 (67.2%) and 15 (25.8%) with a Concordance Index between ≥0.70 and <0.80. Conclusion: A total of 54 operational definitions, 6 nursing diagnoses/outcomes and 29 nursing interventions were validated to compose an ICNP® terminology subset for assistance in the breastfeeding process.
