There is many forms of conceptualize the political participation. For example, direct (plebiscite, referendum) and indirect (vote, representation). The main form of active political participation in contemporary liberal democracy is the political party (Ostrogorski - La Démocratie et les Partis Politiques. Paris : Seuil, 1979). We can talk about active and reactive or passive political participation, in this sense. Or else we can talk in democratic participation (organization of the confidence in the politics) and counter-democratic participation (organization of the distrust) in the work of Rousanvallon (La contre-démocratie. La politique à l'âge de la défiance, Seuil, 2006). An classic approach in the political culture research is the typology participants, subjects and parochials (G. Almond and S. Verba. The Civic Culture: Sage, 1963). Varies in respect of your research interest. Bests regards!
