This presentation is a short summary of an article sent to Journal of Safety Research (Hedlund, Åteg m fl.). Knowledge about hazards in working life and ways to measure, eliminate and minimize them is growing. However, there are obstacles between this knowledge and actions to reduce workers’ exposure to hazards. A common problem is that the workers not are motivated to use available technology and knowledge. It is assumed that the workers’ motivation to actively take part in improvements to the work environment is important for the efficiency of investments for that purpose. With this as a background has a questionnaire that measure motivation for improvements to the work environment been developed. The objective is to present the internal consistency and test-retest reliability of the questionnaire. A second objective is to explore the factorial structure of the instrument comprising different aspects of motivation for work environment improvements.
