Societal abuse refers to the disadvantages that a group experience as a result of unjust social structures. People with mental illness are among the most marginalized, oppressed, devalued and stigmatized populations in our society. They experience a range of societal abuses, including barriers to health care, lack of employment, difficulty accessing and maintaining adequate housing, and discrimination. Nurses are in a unique position to address social inequity and societal abuse as advocates for health and well-being. The author addresses the impact of societal abuse and presents ways in which nurses can advocate for people with mental illness.
