In this fourth edition, the author updates readers on such complex issues as the duty-to-protect, multiple relationships, privacy, privileged communication, and the treatment of minors and clients with HIV/AIDS, particularly with regard to confidentiality. More than 20 articles published since 2003 and additional commentaries have been added on topics such as performing assessments, providing therapy, and conducting research on the Internet; navigating the federal regulations governing the transmission of health care records electronically under the Health Insurance Portability and Accountability Act (HIPAA); responding to requests for "raw data" from parents, insurers, and attorneys; testifying as an expert witness; becoming involved in military interrogations; and practicing ethically under the boundaries of managed care.
