    Introducción: Este estudio evalúa la dimensionalidad del Inventario de Burnout de Maslach (MBI-GS). Método: La muestra fue de 204 profesionales de enfermería de instituciones de salud públicas peruanas. El análisis estructural se realizó con el análisis factorial confirmatorio haciendo uso de estimador acorde a la naturaleza ordinal de los ítems de la escala. La estructura evaluada fue la de tres dimensiones correlacionadas: agotamiento, cinismo y eficacia profesional. Resultados: Se obtuvo un ajuste adecuado luego de remover dos ítems de la dimensión de cinismo y permitir la covarianza de errores de la dimensión de eficacia profesional, X2(73) = 156.61, CFI = .97, TLI = .93, RMSEA = .075. Los coeficientes de consistencia interna fueron adecuados para cada una de las dimensiones (Ω >.80). Conclusión: El MBI-GS es un instrumento que presenta evidencias de estructura interna y confiabilidad en una muestra de personal de enfermería.

    Introduction: This study examines the dimensionality of the Maslach Burnout Inventory (MBI-GS). Method: The sample was composed of 204 professional nurses from Peruvian health public institutions. The structural evaluation was conducted with confirmatory factor analysis using a estimator appropriate for the ordinal nature of the scale items. The assessed structure comprised of three correlated dimensions of exhaustion, cynicism and professional efficacy. Results: An acceptable fit was reached after removing two items from cynicism and allowing correlated errors in professional efficacy, X2(73) = 156.61, CFI = .97, TLI = .93, RMSEA = .075. The internal consistency coefficients were adequate for each of the dimensions (Ω >.80). Conclusion: The MBI-GS is an instrument that presents evidence of internal structure and reliability in a sample of nursing staff.
