Wales has not adopted the English IAPT system and has no centralized training plan for developing cognitive behavioural therapy (CBT) in Wales. However, Welsh Government policy expresses an ambition to improve access to evidence-based psychological therapies for people in Wales. This study focuses on one Welsh Health Board's plan to improve access to CBT. The study aims to benchmark support for effective delivery of CBT in the Health Board against NICE and Department of Health standards, and to establish whether the Health Board's plan is succeeding in developing staff capability and access to evidence-based CBT. Mental health staff funded by the Health Board to complete accredited training in CBT were asked to complete an online questionnaire asking about their training, accreditation, use of CBT, and experience of workplace support for delivering CBT. The standards were taken from the Department of Health competency framework for CBT, NICE guidelines and BABCP safety and confidentiality criteria. The Health Board performed well across seven standards of workplace support for the delivery of evidence-based CBT. Staff funded to undertake accredited CBT training continued to develop and to use CBT in their everyday clinical practice. The study indicates that the Health Board is succeeding in offering good standards of workplace support for CBT, including access to accredited CBT training. A recommendation is made that this be shared with other Welsh Health Boards and that a comparable study be undertaken within an IAPT service.
