Medical Program

MODULE: Behavioral Sciences and Medicine BEHS 640

The course introduces students to the fundamental principles of human behavior and development, with particular emphasis upon the role of behavior within the context of illness and the medical encounter. Theories contributing to the understanding of normal human development and psychopathology are examined.

An overview of several major psychological theories of human behavior is provided, including psychodynamic, behavioral, cognitive, and biological models. Exposition of these systems leads to discussion of a number of topics, including systems of psychotherapy, behavior modification, biological/genetic bases of behavior, psychological assessment, complementary/alternative treatment approaches, and psychopharmacological intervention. An evidence-based approach is adopted in assessing treatment effectiveness, and data supporting the importance of a biopsychosocial approach to patient care is presented.

There is an emphasis upon behavioral medicine/health psychology and the role of cognitive/behavioral approaches in the modification of risky health behavior. Special attention is given to the crucial role of cultural factors within the doctor-patient encounter and health care setting, as well as to the importance of cultural competence in the provision of medical care. The role of the family is noted within this context, and life-disrupting disorders, such as substance abuse, domestic violence, and child abuse are discussed with reference to the physician’s role and responsibility, in terms of detection and intervention.

An additional theme of the course relates to the importance of preventive medicine. To develop this concept, students participate in lectures and group exercises in biostatistics, epidemiology, and health systems. Within the small group setting, students apply the tools of biostatistics and epidemiology to selected public health problems, with an emphasis on the goal of reading the medical literature critically. How behavior, environment, and politics influence health in different societies is also considered----an international comparison of the health systems of several countries is provided and factors underlying existing disparities in health care are explored. Current issues of health care financing and delivery are discussed, along with the important changes in insurance systems, cost containment, and different types of medical practice.

Finally, the fundamental concepts of law that relate to the medical profession are covered in this course. The concerns of society in the legislative, judicial, and administrative regulation of medical practice are emphasized. An overview is provided of the current and probable future expansion of society’s role in the regulation of medical practice of medicine. The basic principles of malpractice are discussed, in addition to topics, such as informed consent, medical ethics, and confidentiality. The course surveys the history of medical ethics and compares the major perspectives on such issues as the conflicts between different types of benefits to patients, the duties of a physician, patient autonomy, termination of pregnancy, end-of-life decisions, social ethics, and rationing of services. This course comprises the third component of the “Medicine in Society” course series.
