The individual personality traits of diabetes patients are important to understanding in order to effectively educate patients about their disease. A variety of perspectives and theoretical backgrounds may be useful to assess individual patients. In this paper, we present information regarding effective diabetes education through the understanding of different personality types and their characteristics. When the individual characteristics of patients are understood and relationships between patients and educators are based on mutual trust and respect, the self-management motivation of patients will be maximized, as will the quality of patient's lives.
