The fourth edition of this established text for students, supervisors, and practitioners in marriage and family therapy emphasizes the multicultural context for intervention efforts. Additionally, the text features an examination of the impact of personal, professional, and institutional layers of values upon both the practitioner and the client/system. Emphasis is retained for classic ethical, legal, and professional concerns along with exploration of contemporary issues such as HIPAA (Health Insurance Portability and Accountability Act), technology, and managed mental health care. Each section of the text concludes with case study examples that focus on applied considerations related to ethical, legal, and professional issues.
