Personal Construct Psychology (PCP), also know as Personal Construct Theory (PCT) is a comprehensive and abstract meta theory that provides us with a powerful tool in exploring and understanding behaviour change, in individuals, organisations, and society as a whole. It is applied by people working in psychology, education, social services, business and in any area dealing with behaviour change. It is also of interest to people who are interested in their own personal development.
