1. Attitudes: This refers to the individual's positive or negative evaluation of performing the behavior. In epidemiological studies, this might involve how people perceive the risks and benefits of getting vaccinated. 2. Subjective Norms: These are the social pressures or expectations from significant others that influence an individual's behavior. For example, if most people in a community believe in vaccination, others are more likely to follow suit. 3. Perceived Behavioral Control: This is the perceived ease or difficulty of performing the behavior, which is influenced by past experiences and anticipated obstacles. For instance, if a person believes they can easily access healthcare facilities, they are more likely to seek medical help.
