The aim of this unit is to assist students in developing an understanding of the theoretical and empirical underpinnings of cognitive behavioural therapy. The unit focuses on providing a grounding in the transdiagnostic application of cognitive behavioural principles and practices to understand human psychological functioning. This includes an emphasis on the understanding of the cognitive framework and its application to issues with depression, anxiety and anger. It also aims to help with the development of knowledge and skills to apply cognitive-behavioural interventions to address functional difficulties.
