Articles in Community and political engagement can lead to self-efficacy, or perceived ability to affect change in one's life.

  • Workers in jobs with high demands and low level of worker control over the decisions leading to those demands show more heart disease and other conditions.

  • Self-efficacy levels predict preventive practices. For example, adolescents with high self-efficacy around communicating about HIV and using a condom were more likely to use condoms and have fewer lifetime sexual partners. And environmental-change self efficacy (belief that one can find and create environments that support physical activity) had a strong relationship with levels of physical activity.

  • Increasing self-efficacy is a key to encouraging behavior change of all kinds.

  • Exercise self-efficacy and perceived exercise control were significantly associated with physical activity level of the elderly.

  • High levels of self-efficacy—i.e. people’s judgments of their capabilities to organize and to execute courses of action required to attain designated types of performances --and outcome-efficacy—i.e. people’s estimation that a given behavior will lead to a certain outcome —were contributing factors for more active public participation in planning workshops for community landscape development in Switzerland.


    Hoppner C, Frick J, Buchecker M. 2008. What drives people's willingness to discuss local landscape development? LANDSCAPE RESEARCH 33(5): 605-622.

  • The efficacy gap negatively predicts collective action. Individuals were more likely to disengage from collaborative action when their perceived influence were far from their desired level of influence.
