The MBTI® Instrument and Health Care Professionals
When health care professionals understand personality type they have more resources for providing quality service to patients and their families. With a knowledge of the framework of the sixteen types, health care providers can adjust communication and create appropriate care programs that best suit the patient. Personality type can assist the professions in many ways including learning how to be flexible with patients, understanding their reactions to disease, appreciating how they experience stress, determining patient compliance with protocols, and knowing how best to deliver challenging medical news.
