Mental health stigma has been categorized into three types. Public stigma refers to the negative attitudes society has toward people with mental illness. Self-stigma or internalized stigma is when an individual with mental illness internalizes these negative attitudes. Institutional stigma is systemic and includes laws or policies from the government or other organizations that, intentionally or not, discriminate against those with mental illness. An example of institutional stigma is the insurance coverage disparities between psychiatric treatment and medical treatment.
