Stigma is indeed a major barrier for seeking treatment. As such, several mental health awareness events focus on reducing stigma in order to encourage patients to come out and seek help and support from health professionals, their family, and community. While these observances do not exclusively focus on coming out, sharing experiences, or seeking help, they do often include this goal in their agenda:
- Mental Health Awareness Month (May): "Mental Health Awareness Month strives to reduce the stigma (negative attitudes and misconceptions) that surrounds mental illnesses." For example, the theme in 2016 was: "Life with a Mental Illness - and called on individuals to share what life with a mental illness feels like for them ... encourage people to speak up about their own experiences ..."
- Children's Mental Health Awareness Day (May 7): "Teens learned about how to take care of their mental health, ... and how to reach out to their parents/guardians to start a conversation around mental health."
- National Day Without Stigma (Oct 9): "The objective of National Day Without Stigma is to eliminate the shame and discrimination surrounding mental health disorders by creating communities of understanding, support, and help-seeking."
- Mental Health Week (Australia) (Oct 10-17): "Raising awareness of mental health issues and reducing stigma associated with seeking support."
- World Mental Health Day (Oct 10): "... an international day for global mental health education, awareness and advocacy against social stigma."
- Mental Illness Awareness Week (Oct 5–11): "Programs during Mental Illness Awareness Week are designed to create community awareness and discussion in an effort to put an end to stigma and advocate for treatment and recovery."
- World Teen Mental Wellness Day (March 2): “raise greater awareness of mental health issues among teens, as well as provide education about removing stigmas surrounding preventative mental health.”
- Mental Health Awareness Week (May 8–14): "... an annual event when there is an opportunity for the whole of the UK to focus on achieving good mental health."
- Asian American Pacific Islander Mental Health Awareness Day (May 10): ".... Asian Pacific American Mental Health Awareness Day will address the mental challenges faced by these communities and provide adequate tools to deal with them."
