The purpose of this study was to validate the psychometric properties of the scale on the work organization in the hospital developed by the National Agency for Support to the performance of health and medical establishments (ANAP) through the implementation of exploratory and confirmatory analyzes. All these analyzes were performed using SPSS 17 software and Amos. The technique of weighted least squares estimation (Weighted Least Square) from the correlation matrix has been used to evaluate the model. The final results propose four factors (collective work, help at work, organizational and informational change, pace constraints and activity peaks). This provides a factorial appropriate structure and acceptable confirmatory evidence.
