Cognitive therapy was developed by Aaron Beck in the 1960s, as an attempt to treat patients diagnosed with depression. The principle of cognitive therapy is that humor and unhealthy behaviors are the result of distorted and rigid thoughts.

This causes people to behave as if the situation was worse than it actually is or makes them unable to see alternatives to the issue. The psychotherapeutic intervention based on cognitive therapy requires patients to actively participate in both the therapy process and to become their own therapists. In the first sessions, patients usually do not realize that such therapy can promote changes, however throughout the sessions the therapy efficiency is evidenced. In Brazil, the early development of cognitive therapy dates back to 1980. The technique 'Think healthy and feel the difference' was developed and can be used in facing various difficulties.

Such technique is essentially based on the concepts of health promotion, quality of life, decision making and cognitive therapy.
The cognitive model assumes that emotion and physical reactions, behavior and thinking are directly related, and thus building healthy cognition assures the improvement of the other areas.
