In this study we report how the communicative method “Motivational Interviewing” (MI) is adapted to the context of health safety inspections. The principal aim is to analyze the effect of MI training on inspectors’ communicative skills and to discuss the outcome in relation to a previous study that involved training of inspectors in a broader context. A further aim of this study is to explore whether it is possible to establish an effect of MI-trained inspectors on property owners’ compliance with the request for reporting radon gas radiation measurement results.
