Stereotypes, prejudices and discrimination towards people with mental illness are common in the public, which is called public stigma. People with mental illness would internalize the public's stereotypes, prejudices and discrimination and apply them to themselves, which is called self-stigma. Both public stigma and self-stigma have serious, pervasive and permanent negative effects on people with mental illness. Therefore, it is of great significance to develop effective anti-stigma interventions. Interventions for mental illness related public stigma and self-stigma are summarized, aiming to provide insights for mental health organizations and professionals to choose, use and creatively design stigma reduction interventions in the future.
