This article describes the nursing care of a schizophrenia patient with DSM-IV axis II diagnosis of borderline personality disorder. The patient presented psychiatric symptoms and signs, such as poor emotional control, manipulative behaviors, low self-esteem, and poor interpersonal relationships. The core symptoms of the personality disorder led to the admission of the patient, so this article mainly deals with the problem of borderline personality and its management. Through holistic nursing assessment, the author confirmed the diagnosis and found that the patient had some related mental health problems, such as, ineffectiveness of coping skills, impairment of social interaction, disturbance of self-concept, and low self-esteem. The author therefore applied the Modeling and Role Modeling model during the process of interpersonal mutual interaction, in order to establish the nurse-patient relationship, to accept the patient's point of view, to promote the patient's capacity for positive thinking, to establish healthy goals, to enhance the sensation of control, to make behavioral contact with the patient, to teach the patient proper conduct to deal with difficulties of emotional control, to improve the patient's interpersonal relationships, and to improve the process of self-identity. During the period of care (Feb. 14th, 2003 - June 6th, 2003), there was marked improvement in the patient's emotional control, adaptive abilities, and self-identity. The results revealed that, from the point of view of the patient, the nurse can improve the patient's willingness to participate in health promotion, to receive help from others, to learn and grow from past experiences and to develop the ability of self-control and mastering of one's own life.
