A lot of so-called 'third-wave' behaviour therapy uses techniques based on the concept of mindfulness - being aware of the moment in a non-judgemental way - including mindfulness-based stress reduction, dialectical behaviour therapy, acceptance and commitment therapy and mindfulness-based cognitive therapy (MCBT). A team of researchers from South Korea looked at the effectiveness of MCBT in treating panic disorder and generalized anxiety disorder. They studied 46 people - some with panic disorder and others with genralized anxiety disorder - and divided them into tow groups. One group received MCBT and the other group received anxiety disorder education. After eight weeks the MCBT group demonstrated significantly more improvement as far as anxiety and depression were concerned. However in terms of somatization (mental-health problems masquerading as physical ones), interpersonal sensitivity, paranoid thoughts and psychoticism there was no difference between the two groups.
