Political efficacy is the term used to describe the amount of faith citizens feel they have on their government. It can also be used to describe the impact citizens believe their actions have on the political process.
If political efficacy is low it means citizens have little faith in their government. However, if political efficacy is high, citizens believe their actions have a positive impact on the government and that the government is doing what is best for them. The political efficacy is typically determined by polls and surveys.
Political efficacy is broken down to internal and external. Internal refers to a persons political knowledge, skills or abilities and is used to determine if a citizen will vote. External refers to how a government responds to the citizens needs.
