I had it years ago, prescribed by my GP and it took place at the surgery. It was to be 6 sessions but I only got 3 and then that Dr, and I have no idea what qualifications he had, just wasn't available for my sessions. It was for slimming, which I don't think anyone else here has mentioned. He made me list everything I ate and we discussed it and he said to cut some of it out. I did gain a lot of weight around then and had never been svelte. I went up to just under 19 stones and was 5'8. It didn't help and I then went to Slimming World, lost 3 stones and stopped as thought I'd do it alone, but began to gain and went to WW and lost the rest and got to goal. This was 2007, and I had to stop weighing in for various reasons, gained a stone and went back, was at goal in 2009 and have weighed in and been below goal every since. So CBT, if that was it, and they called it that, was useless for slimming. Maybe it was a trial. They didn't say so.
