Cognitive behavior therapy is based on the cognitive model: the way we perceive situations influences how we feel emotionally.
For example, one person reading this website might think, “Wow! This sounds good, it’s just what I’ve always been looking for!” and feels happy. Another person reading this information might think, “Well, this sounds good but I don’t think I can do it.” This person feels sad and discouraged.
So it is not a situation that directly affects how people feel emotionally, but rather, their thoughts in that situation. When people are in distress, their perspective is often inaccurate and their thoughts may be unrealistic.
Cognitive behavior therapy helps people identify their distressing thoughts and evaluate how realistic the thoughts are. Then they learn to change their distorted thinking. When they think more realistically, they feel better. The emphasis is also consistently on solving problems and initiating behavioral changes.
