The purpose of this study was to analyze the relationship between citizen engagement in various public participation programs and the participants' assessment of transparency in local government. To examine this relationship, the study focused on three aspects of citizen participation: (1) citizen engagement in participation programs generally, (2) online versus offline participation, and (3) online or offline participation in policymaking phases specifically. A 2009 survey of residents of Seoul, South Korea, was used to test the study hypotheses, as it provided information from 1,014 respondents on their citizen participation and their perceptions of transparency in government. Surprisingly, citizens' engagement in public participation programs was not significantly associated with perceptions of transparency in government. Moreover, citizen participation in online programs had a marginally negative association with assessments of government transparency. However, citizens who engaged in offline participation programs during the policy agenda setting phase indicated a more favorable assessment of transparency in local government.
