Document Summary
Activity that people perform to maintain or improve health. Primary: actions taken to avoid disease or injury. Secondary: actions taken to identify and treat an illness early (to stop or reverse health problems) Tertiary: actions to retard lasting damage, prevent disability, and rehabilitation. Beliefs & attitudes concerning: threat, consequences, importance, benefits, ability, norms. A theory that attempts to explain or predict likelihood of making a specific behaviour choice. Developed in 1950s for the us public health services. In the 1980s, updated to incorporate the role of self-efficacy. Perceived susceptibility, seriousness, benefits and barriers all modified by individual characteristics. Perceived benefits must exceed the perceived barriers or costs for preventive behavior to occur. Likelihood of preventive action is based on the combination of perceived threat and the cost-benefit ratio. Various components tested, not all equally predicative of outcomes. No standard way of measuring its components. Started as theory of reasoned action (ajzen & fishbein, 1980)
