There is widespread support for training in Cognitive Behavioural Psychotherapy (CBP) amongst psychiatrists and from the Royal College of Psychiatrists. One possible way to gain such training is to undertake a diploma or certificate course, a growing number of which exist in the United Kingdom. We report on a postal questionnaire survey of psychiatrists who have completed a CBP diploma course. Psychiatrists described the course as altering their clinical practice and found the skills learned, the format of multidisciplinary learning and of supervision all useful and helpful. However, individuals who undertook a CBP diploma were concerned about their ability to apply these skills and undergo further training, given the time constraints within busy consultant jobs.
