Televised political debates have become increasingly common during the last decades, and they belong to the most important campaign events in countries where they are being held. However, there is still no scholarly consensus with respect to the effects on voting intention from watching televised debates, while there is also a lack of research on debate effects on voting intention in countries with proportional elections and multi-party systems. Against this background, the purpose of this study is to investigate the effects of televised political debates on party choice in the context of the 2006 Swedish parliamentary election. Using an experimental panel design with five waves and including two televised debates with different formats, this study shows that televised debates do have both direct and indirect effects on people’s party choice, and that in order to capture the real impact of televised debates, it is important to focus on individual-level effects and not only aggregate effects.
