This chapter reviews some basic concepts underlying ethical issues in adolescence and provides a step-by-step procedure to address ethical dilemmas involving minor adolescents, based on a deliberative approach. "Deliberation" with the patient, along with involving the opinion of relevant stakeholders if possible, allows for a careful, multidisciplinary examination of all options, the medical and psychosocial consequences, and the moral values stressed by each option. Although the final decision regarding which ethical option should be chosen usually belongs to the health care providers and his or her patient, the deliberative approach provides the ingredients for sound, unbiased decision-making.
