[Validation of workload scale in peruvian workers].

The objective of this study was to validate the Workload Scale in Peruvian workers. The sampling was purposive -170 industrial workers at a chemical and detergent company with a technical education (83 of whom were women)- located in Metropolitan Lima. We used confirmatory factor analysis to evaluate the dimensionality of the items and the equivalence between men and women; reliability estimates of internal consistency; and linear regression of demographic variables on the workload were estimated. A one-dimensional factorial structure was found, and the metric equivalence of the items was similar between men and women; the reliability was acceptable, and workload intensity varied slightly by the type of labor contract.
