This session will review legal and ethical responsibilities of biofeedback and neurofeedback practitioners. Biofeedback professionals are governed in clinical practice by state regulations under the relevant licensing act, professional codes of ethics for his or her home profession, and the Professional Standards and Ethical Principles of Biofeedback (8th rev., January 2016) of the Biofeedback Certification International Alliance (BCIA). The workshop will provide an overview of medical ethics, a discussion of the ethical standards of the American Psychological Association, and a review of the most recent AAPB/BCIA Professional Standards and Ethical Principles of Biofeedback. Violation of such guidelines, even when unintended, invites the risk of lawsuit, criminal prosecution, financial penalties, loss of licensure, and expensive and stressful legal and administrative reviews.
