This report on integrating mental health into primary care, which was developed jointly by the World Health Organization (WHO) and the World Organization of Family Doctors (WONCA), presents the justification and advantages of providing mental health services in primary care. At the same time, it provides advice on how to implement and scale-up primary care for mental health, and describes how a range of health systems have successfully undertaken this transformation.

As this report will show, treating mental disorders as early as possible, holistically and close to the person's home and community lead to the best health outcomes. In addition, primary care offers unparalleled opportunities for the prevention of mental disorders and mental health promotion, for family and community education, and for collaboration with other sectors.
