Abstract
The purpose of this literature review is to identify mental health nursing's contribution to the care and treatment of patients with a first episode of psychosis; A systematic literature review was undertaken, with 27 articles selected for study. Five domains were identified: development of therapeutic relation, relapse prevention, enhancement of social functioning, stimulation of medication adherence, and support of family members. The level of evidence of mental health nursing's contribution to the care and treatment of those undergoing their first episode of psychosis was low. Our review suggests that mental health nurses should reflect upon their own daily practices within the five domains.
