In this paper we study both long term and short term individual effects of political participation at the local level. Participatory theorists argue that political participation could lead to individual emancipation in terms of a rise of political knowledge and, in the long term, political trust. Indeed, in the short term the increased political knowledge associated with participation might enable citizens to better define their self-interest, which may be inconsistent with actual policies pursued by the local authorities and thus might be conductive to distrust. In the empirical part we will test these assertions using two-wave panel data for a random sample of 457 individuals in the district of Deurne (Antwerp – Belgium). Our results suggest that in the short term participation leads to more local political knowledge and distrust in the local administration. However, we do not find a significant increase in political trust in the long term.
