It does assume that an individual's thought patterns - how reality is viewed - produce his (or her) feelings.

These combined thoughts and feelings result in an individual's day to day behavior. When the behavior is counterproductive, the cognitive therapist challenges the client to become aware of the thinking errors that cause painful feelings and lead to negative action.

The cognitive therapist guides the client to correct distorted thinking and to introduce alternative, more positive thoughts. A new view of reality evolves, opening up possibilities for more productive feelings and effective behavior.
