摘要:Globally, more than 70% of people with mental illness receive no treatment from health care staff. Evidence suggests that factors increasing the likelihood of treatment avoidance or delay before presenting for care include (1) lack of knowledge to identify features of mental illnesses, (2) ignorance about how to access treatment, (3) prejudice against people who have mental illness, and (4) expectation of discrimination against people diagnosed with mental illness. In this article, we reviewed the evidence on whether large-scale anti-stigma campaigns could lead to increased levels of help seeking. INCREASING EVIDENCE SUG gests that significantly greater barriers exist to receipt of mental health care in comparison with physical health care. Worldwide, more than 70% of young people and adults with mental illness do not receive any mental health treatment from health care staff. 1 The difference between true prevalence and treated prevalence can be called the treatment gap. 2 This article describes the roles that stigma and discrimination contribute to the treatment gap 3,4 and assesses the evidence that public health approaches to stigma and discrimination can facilitate access to mental health care. We present new data from the evaluation of Time to Change, England’s largest ever program to reduce mental illness stigma and discrimination. 5
