RESUMEN
RESUMEN

Objetivo:

Analizar el grado de preservación de las propiedades psicométricas del Nursing Activities Score (NAS), según análisis de confiabilidad y validez del instrumento. Material y

método:

Estudio instrumental para la adaptación y validación de un instrumento que mide la carga de trabajo de enfermería en Unidades de Cuidados Intensivos y que abarca más del 80% de las actividades de enfermería, estimando la asignación diaria de pacientes al personal de enfermería, según las necesidades de cuidados de los mismos. La validación se realizó en seis unidades de cuidados intensivos de dos hospitales de Santiago de Chile.

Resultados:

La media NAS fue de 70,86%. Para el análisis factorial exploratorio se excluyeron los ítems que no presentaron variabilidad (2, 3, 15, 16 y 18). Se utilizó el método de extracción de factores de mínimos cuadrados en el programa Factor y se decidió la solución de 1 factor que explicó el 12,8 % de la varianza total del instrumento. La estructura factorial propuesta agrupó a los ítems en 1 factor y los ítems 1, 5, 6, 7, 8, 13, 14, 19, 20, 22 y 23 no presentaron una comunalidad adecuada. El estadístico de Kuder-Richardson fue de 0,886. La validez de criterio externo presentó una correlación alta y positiva (r= 0,601).

Conclusión:

Debido a la relevancia teórica y práctica y atingencia conceptual de los ítems reportada en el proceso de validación de contenido, se ha decidido no recomendar la eliminación de estos ítems y seguir haciendo estudios de validación en otras poblaciones.
ABSTRACT
ABSTRACT

Objective:

Analyse the degree to which psychometric properties are preserved in the Nursing Activities Score through assessments of instrument reliability and validity.

Method:

Assessments of instrument adaptation and validation that measures the workload of nursing in Intensive Care Units and that covers more than 80% of nursing activities, estimating the daily allocation of patients to the nursing staff according to the patients' care needs. The instrument's reliability was assessed in six intensive care units located in two hospitals in Santiago, Chile.

Results:

The mean nursing activities score was 70.86%. For exploratory factor analysis, items without variability were excluded (2, 3, 15, 16 and 18). The least squares factor extraction method was used, executed in the Factor software, and it resulted in one factor explaining 12.8% of total instrument variance. The proposed factor structure grouped items in one factor; however, items 1, 5, 6, 7, 8, 13, 14, 19, 20, 22 and 23 did not present adequate communality. The calculated value for the Kuder-Richardson formula was 0.886. The Nursing Activities Score instrument was highly and positively correlated with the Therapeutic Intervention Scoring System (r = 0.601), used as an external validation criterion.

Conclusion:

Due to theoretical and practical relevancy, as well as conceptual connections of the items selected during the content validation process, we recommend that these items are not eliminated from the Nursing Activities Score instrument. Additional validation studies should be conducted in other populations.
