The concept of political efficacy was originally formulated to capture citizens’ subjective attitudes toward politics, more specifically, their notions about their role and position within the political system. It is "the feeling that individual political action does have, or can have, an impact upon the political process, i.e., that it is worthwhile to perform one’s civic duties. It is the feeling that political and social change is possible, and that the individual citizen can play a part in bringing about this change” (Campbell et al, 1954: 187). The concept is usually broken into two separate components: one external and one internal variant.
