Cognitive-Behavioural Therapy is the most commonly given form of therapy you will find in the NHS. It originated from the work of psychologists in the 1970s and since then has been refined and adapted many times. The technique focuses on the present and the future. There is great emphasis on changing your thoughts and then your behaviour rather than going back to the past. Modern CBT approaches often use mindfulness strategies as well.
CBT has a very good evidence base from research and it is effective for lots of people. However, it doesn’t work for every person. Some people need to go back to their past to understand it so that they can let it go. Understanding the root cause of your problem can free you of it forever. CBT won’t do this so if this sounds like you you may prefer other forms of psychotherapy.
I tend to blend CBT with other approaches in my therapy work. It can be very successful when combined with hypnotherapy.
