RT Journal Article T1 An Evaluation of the NANDA International, Inc., Diagnostic Classification Among Spanish Nurses: A Cross-Sectional Study A1 Rodríguez Suárez, Claudio Alberto A1 Mariscal Crespo, María Isabel A1 Hernández de Luis, María Naira A1 Martins Teixeira da Costa, Emilia A1 González de la Torre, Héctor A1 Camacho Bejarano, Rafaela AB Background/Objectives: The NANDA International, Inc., (NANDA-I) diagnosticclassification is the most widely used standardized nursing language internationally.The EVALUAN-I tool was developed to evaluate the NANDA-I diagnostic classification.The aim was to analyze the use of the NANDA-I diagnostic classification among Spanishnurses and assess its correlation with sociodemographic characteristics.Methods: A crosssectionalstudy was conducted on a non-probabilistic sample of Spanish nurses workingin clinical, management, and academic settings using the EVALUAN-I tool (September2019–December 2020). The analysis was conducted using R® (version 3.6.3, Lavaan package;R Core Team, 2020), with statistical significance set at p < 0.05. This study was approvedby the Research Ethics Committee (2019-190-1). Results: A total of 483 responses were obtained.There was a correlation between the intensity of use of NANDA-I and its applicationin practice (polychoric correlation = 0.50; p < 0.001). Nurses with a PhD degree considerednursing diagnoses to be less evidence-based (p = 0.037) but more useful (p = 0.035).Academic and research nurses stated that NANDA-I was more useful (p = 0.007), evenfor exclusive responsibilities (p = 0.034), and that it provided greater significance to diagnoses(p = 0.0012). Conclusions: NANDA-I is the most widely used standardized nursinglanguage in Spain. Nurses’ academic qualifications and work environment significantlyinfluence their perceptions and use of NANDA-I. Advanced education fosters a criticalyet positive perspective, highlighting a relationship between the intensity of its use, itsapplication in clinical practice, and the nurse’s educational background. Tools such asEVALUAN-I promote its integration and evidence-based practice, but challenges remainin improving perceptions, scientific evidence, and visibility in electronic health records toenhance its clinical impact and nursing recognition.
