Counselors must deal with a variety of ethical issues and dilemmas. Counseling and psychotherapy are also guided by encompassing ethical guidelines, defined as ethical principles (high standards for ethical behavior). This chapter describes the six core ethical principles underlying ethical analysis in the profession of counseling. These principles are autonomy, nonmaleficence, beneficence, justice, fidelity and veracity. The chapter contrasts principle ethics with virtue ethics. The concept of justice involves fairness and equality in access to resources and treatment. Distributive justice involves access to resources and services that may be considered scarce. The chapter discusses the processes of considering their application to ethical issues and defines the concepts of balancing, weighing, and assigning prima facie merit to principles. Ethical standards are specific profession-relevant directives or guidelines that reflect the best ethical practice of professionals. The chapter discusses the principles with attention to how they inform ethical standards and practices in counseling.
