Purpose: To develop and validate a tool to evaluate the NANDA International, Inc. diagnostic classification. Methods: The tool, EVALUAN-I, was validated in a non-probabilistic sample (N = 460) on Spanish Registered Nurses (September–December 2019) in two phases. First, design and construct the instrument in three steps: (1) literature review to define the construct focusing on the orientation toward nursing concepts and theoretical foundations, the level of scientific evidence, the structural configuration, the applicability, the nurses’ clinical reasoning skills, and the attitudes toward nursing diagnosis, (2) substantiation of the questionnaire items and design according to the criteria for a diagnostic classification, (3) expert test to establish the face validity and content validity. The second phase revolved around (4) conducting a pilot test and measuring the temporal stability (test-retest) and Cohen's kappa coefficient; assessing psychometric properties by measuring (5) reliability (internal consistency using Cronbach alpha and interfactor correlation) and (6) construct validity (exploratory and confirmatory factor analysis). The manuscript follows the STROBE checklist. The study was approved by the Research Ethics Committee with registration number 2019-190-1. Findings: EVALUAN-I displayed moderate test-retest stability, adequate construct validity, and excellent reliability. The confirmatory factor analysis provided evidence about the configuration of EVALUAN-I in relation to nine analytical dimensions: clinical competence, nurses’ reasoning skills, attitudes towards nursing diagnosis, discipline's central concepts, classification's contents, physiopathological attributes, level of scientific evidence, diagnostic precision, and conceptual correspondence between terminologies. Conclusions: EVALUAN-I is a valid and reliable instrument, which can be used to improve the epistemological, normative, and intuitive configuration of NANDA International, Inc. in a structured, systematic manner. Implications for Nursing Practice: Comprehensive evaluation of NANDA International, Inc. in different clinical settings around the world using a validated instrument, like EVALUAN-I, would allow strengths and weaknesses to be identified and contribute to the classification's development and practical application.

Introduction: nurses have different opinions and attitudes about the clinical functionality of Nursing Diagnosis.Objective: to describe the attitudes of Nursing professionals towards the Nursing Diagnosis.Method: observational, descriptive, cross-sectional study in a hospital in the Canary Islands (Spain). Position on Nursing Diagnosis is a validated instrument to measure the attitudes of nurses towards the Nursing Diagnosis with excellent reliability. It is made up by a coded scale of 20 pairs of opposite adjectives in which the interviewed must position himself; extreme scores 1 (most negative attitude) and 7 (most positive attitude); 4 middle value; 140 maximum score and 20 minimum one. Reliability analysis was performed using Cronbach's alpha and inter-element correlation. Frequency distribution for qualitative variables and proportion for quantitative variables. Association analysis.Results: the study population was N=170. The scale has shown high reliability (α=0.955) as well as adequate power to explain the total variance (66.13%). The global mean score was 74.41 (sd=23.53); the worst attitude was Routine (µ=2.91; sd=1.55) while the best attitude was Positive (µ=4.20; sd=1.56).Conclusions: the attitudes of the nurses in our environment are similar to other contexts, with global scores lower than the average. The increase in academic training and the use of the Nursing Diagnosis in the work environment seem to improve the attitudes of this professionals, mainly with regard to acceptance, comfort, ease, relevance, validity, creativity and gratification. Introducción: Las enfermeras tienen opiniones y actitudes diferentes sobre la funcionalidad clínica de los Diagnósticos Enfermeros.Objetivo: Describir las actitudes de los profesionales de Enfermería ante el Diagnóstico Enfermero.Método: Estudio observacional, descriptivo, transversal en un hospital de las Islas Canarias (España). Position on Nursing Diagnosis constituye un instrumento validado con excelente fiabilidad. Conformado por una escala codificada de 20 parejas de adjetivos opuestos; puntuaciones extremas 1 (más negativa) y 7 (más positiva); valor central 4. Puntuación máxima 140 y mínima 20. Se realizó análisis de fiabilidad mediante Alfa de Cronbach y correlación interelementos. Distribución de frecuencias para variables cualitativas y de proporción para cuantitativas. Análisis de asociación. Resultados: Población muestral n=170. La escala ha expuesto alta fiabilidad (α=0,955) y adecuado poder de explicación de la varianza (66,13%). La puntuación media global fue 74,41 (sd=23,53); la peor actitud correspondió a Rutinario (µ=2,91; sd=1,55) mientras que la mejor fue Positivo (µ=4,20; sd=1,56). Conclusiones: Las actitudes de las enfermeras son similares a las observadas en otras realidades, con puntuaciones globales inferiores a la media. El incremento de la formación académica y del uso del Diagnóstico Enfermero en el entorno laboral parecen mejorar las actitudes de estos profesionales, principalmente en lo que respecta a su aceptación, comodidad, facilidad, relevancia, validez, creatividad y gratificación.

Background/Objectives: The NANDA International, Inc., (NANDA-I) diagnostic classification 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 Spanish nurses and assess its correlation with sociodemographic characteristics. Methods: A cross-sectional study was conducted on a non-probabilistic sample of Spanish nurses working in clinical, management, and academic settings using the EVALUAN-I tool (September 2019–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 approved by 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 application in practice (polychoric correlation = 0.50; p < 0.001). Nurses with a PhD degree considered nursing 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), even for 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 nursing language in Spain. Nurses’ academic qualifications and work environment significantly influence their perceptions and use of NANDA-I. Advanced education fosters a critical yet positive perspective, highlighting a relationship between the intensity of its use, its application in clinical practice, and the nurse’s educational background. Tools such as EVALUAN-I promote its integration and evidence-based practice, but challenges remain in improving perceptions, scientific evidence, and visibility in electronic health records to enhance its clinical impact and nursing recognition.

Objetivo: el objetivo principal de esta revisión es identificar las mejores evidencias específicas disponibles en la literatura científica sobre el cáncer de mama en niñas y adolescentes.Metodología: búsqueda avanzada en distintas bases de datos de las que se han recopilado 8 artículos con altos índices de impacto según JCR publicados en los últimos 5 años y disponibles a texto completo.Resultados: existen factores de riesgo modificable y no modificables relacionados con el cáncer de mama en niñas y adolescentes. Es de gran importancia el conocimiento de la enfermedad, las pruebas diagnósticas, la imagen de la mujer con cáncer de mama y su preocupación por el embarazo tras el diagnóstico en este grupo poblacional. Es necesario establecer sistemas enfermeros específicos para las afectadas o en riesgo de presentar cáncer de mama, así como para su familia.Conclusión: La figura de la enfermera cobra aún mayor importancia en este ámbito. Los profesionales de enfermería deben estar perfectamente formados y tener una cartera de servicios para la prevención del cáncer de mama en niñas y adolescentes, pruebas diagnósticas específicas para este grupo vulnerable y el cuidado de la población afectada. El apoyo educativo sería la estrategia de elección para llevarlo a cabo.
