The British Association for Behavioural and Cognitive Psychotherapies, the lead organisation for cognitive behavioural therapy (CBT) in the UK and Ireland, is 50 years old this year. In this episode Dr Lucy Maddox explores how CBT has changed over the last 50 years. Lucy speaks to founding members Isaac Marks, Howard Lomas and Ivy Blackburn, previous President David Clark, outgoing President Andrew Beck and incoming President Saiqa Naz about changes through the years and possible future directions for CBT. Transcript  Dr Lucy Maddox:        Hello, my name is Dr Lucy Maddox and this is Let’s Talk about CBT, the podcast brought to you by the British Association for Behavioural and Cognitive Psychotherapies or BABCP. This episode is a bit unusual, it’s the 50th anniversary of the British Association for Behavioural and Cognitive Psychotherapies this year. And I thought this would be a nice opportunity to explore some of the history of cognitive behavioural therapy, especially the last 50 years.                                     Some of the roots of CBT can actually be traced way back. Epictetus, an ancient Greek Stoic philosopher wrote that man is disturbed not by things, but by the views he takes of them. This is pretty close to one of the main ideas of cognitive behavioural therapy, that it’s the meaning that we give to events, rather than the events themselves which is important. But actually, cognitive behavioural therapy started off without the C. To find out more, I made a few phone calls. Isaac Marks:               Hello, Isaac Marks here. Dr Lucy Maddox:        Isaac Marks was one of the founding members of BABCP and a key figure in the development of behavioural therapy in Britain. I asked him if he could remember what CBT was like 50 years ago. Isaac Marks:               Originally it was just BT and a few years later the cognitive was added. At the time, the main psychotherapy was dynamic psychotherapy, sort of Freudian and Jungian. But just a handful of us in Groote Schuur Hospital psychiatric department, that’s in Cape Town, developed an interest in brief psychotherapy. And I was advised if I was really interested in it and I was thinking of taking it up as a sub profession, that I should come to the Maudsley in London. Dr Lucy Maddox:        Isaac and his wife moved to London from South Africa and Isaac studied psychiatry at the Maudsley Hospital in Camberwell. What was it about CBT that had interested you so much? Isaac Marks:               Because it was a brief psychotherapy, much briefer than the analytic psychodynamic psychotherapy. We were short of therapists and there wasn’t that much money to pay for extended therapy, just a few sessions. Six or eight sessions something like that could achieve all what one needed to. They had quite a lot of article studies. Dr Lucy Maddox:        And I guess that’s still true today, that those are some of the real standout features of it, aren’t they? That it is a briefer intervention than some other longer-term therapies and that it’s got a really high quality evidence base. Isaac Marks:               I think that’s probably true, yes. Howard Lomas:          There was a group that met at the Middlesex Hospital every month. And that was set up by the likes of Vic Meyer, Isaac Marks, Derek Jayhugh. Dr Lucy Maddox:        That’s Howard Lomas, another founding member of BABCP remembering how the organisation got set up 50 years ago from lots of different interest groups coming together. Howard Lomas:          These various groups that got together and said, “Why don’t we have a national organisation?” So that was formed back in 1972. Dr Lucy Maddox:        Howard’s professional background was different to Isaac’s psychiatry training, but he found behaviour therapy just as useful
