What organization provides the standards for professional ethics that psychologists must follow in Massachusetts?

The American Psychological Association (APA) provides the established standards for professional ethics that psychologists must adhere to in Massachusetts and across the United States. The APA's Ethical Principles of Psychologists and Code of Conduct outlines the responsibilities psychologists have to their clients, the public, and the profession. This document serves as a foundational guideline for ethical practice, emphasizing principles such as beneficence, fidelity, integrity, and justice.

Psycho-ethical obligations are crucial in maintaining public trust in the profession and ensuring that practitioners engage in responsible behavior in their interactions with clients and other professionals. Psychologists in Massachusetts are expected to be familiar with these standards as part of their professional training and ongoing practice. Compliance with the APA's ethics code not only helps protect the welfare of clients but also promotes the integrity and credibility of the field as a whole.

While other organizations listed may have their own values and ethical guidelines, the APA's code is the primary and most widely recognized source for ethical standards in psychology. Thus, it is the correct choice for this question regarding ethical standards in the practice of psychology in Massachusetts.
