Theory of Reasoned Action/Planned Behavior
Two closely associated theories – The Theory of Reasoned Action and the Theory of Planned Behavior – suggest
that a person's health behavior is determined by their intention to perform a behavior. A person's intention to
perform a behavior (behavioral intention) is predicted by 1) a person's attitude toward the behavior, and 2)
subjective norms regarding
the behavior. Subjective norms are the result of social and environmental surroundings and a person's
perceived control over the behavior. Generally, positive attitude and positive subjective norms result in
greater perceived control and increase the likelihood of intentions governing changes in behavior.
Theory of Reasoned Action/Planned Behavior Examples

Considerations for Implementation
The Theory of Reasoned Action/Planned Behavior provide useful information for predicting health behaviors and
planning and implementing health promotion and disease prevention programs. Subjective norms can be used to
describe the behaviors of healthcare providers, patients, care providers, and others in the community. These
theories have been used to guide health promotion and disease prevention asthma counseling and treatment
compliant, tobacco use interventions, and anti-drug media campaigns, among other topics.
