['To identify the problems nurses encounter in a Neonatal Unit and adapt them to the corresponding NANDA (North American Nursing Diagnosis Association) diagnostic categories for their validation in our environment.', 'A Nominal Group Technique (NGT) was developed to identify the problems that nurses detect and solve. Identified problems were catalogued with their corresponding diagnostic label using the NANDA diagnostic taxonomy. A concordance study was carried out between two observers, using the Kappa coefficient.', 'During the study period, 36 different NANDA diagnostic categories were identified for use. From these, 5 have been validated with an excellent or good concordance (K > 0.70) and 2 with an average concordance (0.70 > K > 0.40). The remaining categories did not occur with enough frequency during the study period to apply statistical treatment.'] Does nANDA nursing diagnose identification and validation in a neonatal unit?
