In this study I have investigated how role playing may change young students´ attitudes and behavior. According to the Swedish National Agency for Education´s governing document, Läroplanen för de frivilliga skolformerna, 1994, the principals at Swedish schools are required to inform students about the risks connected with alcohol and traffic. Scientists bring to our attention the need for emotional information to change attitudes and behaviors. The Historical Wine- and Sprits Museum in Stockholm has arranged a role play that gives emotional information to school students in order to affect their attitudes towards drunk driving. My study is a qualitative examination of this role play. One of my conclusions is that the strongest effect of the Historical Wine- and Spirit Museum’s role play lies on the cognitive and affective part of young students´ attitudes towards driving under the influence of alcohol. However, the role play is not using the other powerful effect a role play can have, which is learning to behave differently by actually acting. This leaves room for improvements. The study furthermore looks into different theories about role playing and how to build a role play to make an effective change in attitudes and behaviors. This is also investigated in the empirical part of the study in the form of interviews. For instance, arguments should always be thought out by the participants themselves and the time for preparing arguments has an effect on the effectiveness of the role play.
