How important are political interest and internal political efficacy in the prediction of political participation? Longitudinal evidence from Germany

This study aims to disentangle the effects of interest in politics and internal political efficacy in the prediction of different political activities. The analysis examines the hypothesis that political interest is a more important precursor of electoral and unconventional political participation, and that both political interest and efficacy are required to promote participation in political parties. Using the German Longitudinal Election Study, multiple regression analyses yield that political efficacy is a strong and positive predictor of intentions to participate in party politics and unconventional political behaviour. Political interest has differential effects on voting conditional on whether respondents are surveyed before or after elections, and differential moderated effects appear for conventional and unconventional political action. The findings are discussed with respect to the importance of political interest and efficacy for citizen participation.
