Worker Training in Job Safety and Health: how do we know it Works?

Two methods of occupational disease and injury prevention specifically required by Federal law are education and training of workers in job safety and health. Basic assumptions underlying these strategies are that they will increase safe behavior thereby reducing health risk. However, questions continue to arise regarding the effect of ongoing training as a preventive measure and, therefore, about the practical usefulness of these assumptions. The purpose of this study was to examine the extent to which evaluations of ongoing training programs can provide information to test the basic assumptions. A self-administered mail survey concerning the evaluation practices of occupational health professionals responsible for the evaluation of health and safety training programs was conducted. Results suggest that for many evaluations the information collected is inappropriate for the uses to which it is put. Furthermore, the results also suggest that measurement validity is a problem. Thus, in effect, we have no way of knowing whether or not the majority of training programs are effective.
