Objective: To validate the content of the diagnosis Risk for disturbed maternal-fetal dyad in high-risk pregnant women. Method: Nursing diagnosis content analysis study in which 48 nurses evaluated agreement regarding title, definition, class, and domain of the studied nursing diagnosis, as well as the relevance of its antecedents. The items were considered relevant when the Confidence Interval of the Content Validity Index was 0.8 or higher. When lower, the item was modified or excluded according to the experts’ suggestions. Results: Out of 21 antecedents, 14 were considered relevant. The labels of five elements considered irrelevant were changed, and one item was excluded. The experts did not choose the title and definition proposed by NANDA-I, preferring instead the ones suggested in this study. The experts agreed with the class and domain proposed by the taxonomy. Conclusion: Ten risk factors, four populations at risk, and six associated conditions for this nursing diagnosis were maintained; these may provide a basis for nursing practice. The phase of clinical validation is suggested to be conducted to corroborate this study’s results.
