In psychology, attitude is a psychological construct that is a mental and emotional entity that inheres or characterizes a person, their attitude to approach to something, or their personal view on it. Attitude involves their mindset, outlook and feelings.[1] Attitudes are complex and are an acquired state through life experience. Attitude is an individual's predisposed state of mind regarding a value and it is precipitated through a responsive expression towards oneself, a person, place, thing, or event (the attitude object) which in turn influences the individual's thought and action.

• attitude of health personnel
• attitude to computers
• attitude to death
• attitude to health
  • health knowledge, attitudes, practice

Daniel Katz classified attitudes into four different groups based on their functions.

• Utilitarian: provides general approach or avoidance tendencies
• Knowledge: organizes and interprets new information
• Ego-defensive: protects self-esteem
• Value-expressive: expresses central values or beliefs

Utilitarian People adopt attitudes that are rewarding and that help them avoid punishment. In other words, any attitude that is adopted in a person's own self-interest is considered to serve a utilitarian function. For example, a person who has a condo would pay property taxes. If that leads to an attitude that “increases in property taxes are bad”, then the attitude is serving a utilitarian function.

Knowledge Several studies have shown that knowledge increases are associated with heightened attitudes that influence behavior.[47] The framework for knowledge is based on significant values and general principles. Attitudes achieve this goal by making things fit together and make sense. As a result, people can maintain a sense of stability and meaning within their worldview. For example:

• I believe that I am a good person.
• I believe that good things happen to good people.
• Something bad happens to Bob.
• So, I believe Bob must not be a good person.

When a person is relying on a single dimension of knowledge and that dimension isn't directly related to their behavior goal, that person might conclude that the attitude is wrong.[47]

Ego-Defensive This function involves psychoanalytic principles where people use defense mechanisms to protect themselves from psychological harm. Mechanisms include denial, repression, projection, and rationalization.

The ego-defensive notion correlates with Downward Comparison Theory, which argues that derogating a less fortunate other increases a person's own subjective well-being. A person is more likely to use the ego-defensive function when they suffer a frustration or misfortune.

Value-Expressive Identity and social approval are established by central values that reveal who we are and what we stand for. Individuals define and interpret situations based on their central values. An example would be attitudes toward a controversial political issue.
