The APA Ethics Code Commentary and Case Illustrations is a comprehensive examination of the APA Ethics Code and the complex process of ethical decision making. The authors describe the Standards of the Code, their application, and how the Code can guide psychologists when ethical dilemmas arise. Case illustrations are used throughout the book to demonstrate the process a psychologist will need to work through when confronted with an ethical dilemma. In a wide variety of case illustrations that address most of the 89 Standards of the Ethics Code, the authors describe a realistic scenario, identify the ethical dilemma, map out the decision-making factors, and present appropriate resolutions to the dilemma. This book is meant to specifically include commentary and case illustrations that are applicable to the many areas of psychology (e.g., consulting, forensic, education and training, research, organizational, public and private practice). The authors also closely examine how the specific ethical standards in the Code relate to its general principles (e.g., beneficence and nonmaleficence, fidelity and responsibility). The authors show that a thorough working knowledge of relevant rules, regulations, and professional codes of ethics, combined with a systematic method of approaching and resolving dilemmas are essential for the ethical practice of psychology. This book of commentary is a must-read for psychologists at all levels of professional experience, from beginning students to those whose entire professional lives have been devoted to the field of psychology. The authors encourage psychologists to accept the invitation offered in the preamble to the APA Ethics Code to embrace a lifelong commitment to the highest ethical standards in the profession of psychology.
