Emanating Effects: The Impact of the Oregon Citizens’ Initiative Review on Voters’ Political Efficacy

Deliberative processes can alter participants’ attitudes and behavior, but deliberative minipublics connected to macro-level discourse may also influence the attitudes of non-participants. We theorize that changes in political efficacy occur when non-participants become aware of a minipublic and utilize its deliberative outputs in their decision making during an election. Statewide survey data on the 2010 and 2012 Oregon Citizens’ Initiative Reviews tested the link between awareness and use of the Citizens’ Initiative Review Statements and statewide changes in internal and external political efficacy. Results from a longitudinal 2010 panel survey show that awareness of the Citizens’ Initiative Reviews increases respondents’ external efficacy, whereas use of the Citizens’ Initiative Review Statements on ballot measures increases respondents’ internal efficacy. A cross-sectional 2012 survey found the same associations. Moreover, the 2010 survey showed that greater exposure to—and confidence in—deliberative outputs was associated with higher levels of both internal and external efficacy.
