Validación del Cuestionario Nórdico Estandarizado de Síntomas Musculoesqueléticos para la población trabajadora chilena, adicionando una escala de dolor

Abstract Objective: to validate the general section of the Nordic Standardized Questionnaire (NSQ) for the Chilean population adding a numerical pain intensity scale. Method: NSQ was applied including a pain scale and it was compared with a functional clinical evaluation as the «gold standard», in a sample of 114 workers from 6 business areas. Validation through test-retest for NSQ was done in a sample of 54 workers. Results: concordance values between 0.119 and 0.435; positive predictive values between 0%; and 53.6% and negative predictive values between 80.3% and 100% were obtained. The numerical pain intensity scale presented a correlation between 0.3 and 0.4 for most segments. The validation test-retest produced medium and high concordance and correlation values. In this way a Chilean version of NSQ with known psychometric standards is made available to interested parties (clinical doctors, insurers, researchers).
