The basic principle of CBT is that the way we think in specific situations affects how we feel emotionally and physically, and alters our behaviour.
Everyone will have their own, individual response to a particular event. For example, different individuals can react very differently to a busy day at work. The same applies to a wide variety of situations, including reactions to physical illness and disability.
No individual reaction is right or wrong. However, the way people react to events can often worsen their lives as a vicious cycle. In CBT, we try to identify the most important thoughts, feelings and behaviours that make up these reactions and decide whether these responses are rational and helpful. By identifying whether our reactions are helpful or unhelpful in achieving specific life goals, we can make choices about how to respond to different circumstances.
