Ethics plays a dual role in psychiatry. The extrinsic role is in defining the rules of ethical conduct for the psychiatrist as a professional dealing with patients, peers and society at large. The intrinsic role is in defining ethical or moral conflict as a determining component in the construction of symptoms of mental disorder. Ethical considerations play a role in the truthful description of the disorder, diagnosis, dynamic formulation and the doctor-patient relationship in treatment. In treatment, there is a need to acknowledge 2 dimensions of psychological conflict: (1) an appraisal of the actual realistic moral conflicts due to symptomatic unethical conduct that goes against one's normative conscience, and (2) resolution of past conflicts arising from unconscious or repressed aspects of the neurotic conscience or superego, i.e. a holdover of unreflected obedience to parental authority. The resolution of past and ongoing conflicts promotes growth toward autonomy of moral judgment, free choice and moral responsibility.
