Revised to reflect the latest edition of the American Psychological Association’s (APA) Ethical Principles of Psychologists and Code of Conduct, Celia B. Fisher’s acclaimed Decoding the Ethics Code Fifth Edition explains and puts into practical perspective the format, choice of wording, aspirational principles, and enforceability of the code. Providing in-depth discussions of the foundation and application of each ethical standard to the broad spectrum of scientific, teaching, and professional roles of psychologists, this unique guide helps practitioners effectively use ethical principles and standards to morally conduct their work, avoid ethical violations, and, most importantly, preserve and protect the fundamental rights and welfare of those whom they serve.
