Objective: To build, validate and apply a questionnaire to verify nurses' knowledge about infant feeding.
Material and methods: A cross-sectional, descriptive and analytical study conducted with a sample of 231 nurses, in the year 2017. The study was developed in three stages: construction and validation of the instrument, and application of the instrument to the population. The data were analyzed by Content Validity Index - CVI, statistical tests of association/correlation, Linear-by-Linear Association and averages tests.
Results: The instrument was validated with 21 multiple choice questions, and reached an I-CVI equal to or above 0.80 in all questions. It was evidenced that nurses were mostly female, with an average age of 38.7 years and had worked for more than 10 years in the Family Health Strategy. The knowledge of the majority (65.4%) fell into the medium level category, between 51% to 80% of correct answers on the questions.
Conclusion: The instrument was validated in content in the three aspects: language clarity, practical relevance and theoretical relevance. After its application, it was found that the knowledge of the study population about infant feeding needs to be improved.
