The need for mental health promotion.

OBJECTIVE: To examine the concept and evidence for mental health promotion, within an understanding of mental health and mental illness and their determinants.
METHOD: A selective review of literature and opinion in the fields of public health and mental health.
RESULTS: Mental health and mental illness are often given a low priority, despite growing evidence of the burden of disease and costs to the economy. Improving mental health and reducing mental illness will improve quality of life, public health and productivity. The needs for mental health promotion are complementary to the needs for prevention and treatment of mental illness. The required activities are different. Mental health professionals have a necessary but not sufficient role in mental health promotion.
CONCLUSIONS: An understanding that mental illnesses are treatable can encourage early entry to care, improve outcomes and lessen the stigma and discrimination related to mental illness. In primary health care there is some evidence that preventive interventions with groups at high risk of depression can prevent episodes of ill health. However, mental health promotion involves another dimension. Better understanding of the nature of mental health and mental illness is the key to changing the priorities, policies and practices in education, law, social services, housing and health critical in turn to the conditions conducive to mental health.
