A comprehensive handbook covering a range of ethical issues which psychologists working in practice or research are likely to come across. It contains an explanation of the background of ethical theory and details international covenants and a range of ethical codes from around the world, including the UK, Europe, US, Canada, Australia and New Zealand. Rather than addressing ethics for each particular discipline in psychology the book looks at common ethical concerns such as bodily contact, the use of aversive procedures and referrals. This comprehensive guide includes decision trees, case studies, legal issues and key ethical principles to make it of immediate application.
