Severe mental illness has been likened to drug addiction, prostitution, and criminality (37,38). Unlike physical disabilities, persons with mental illness are perceived by the public to be in control of their disabilities and responsible for causing them (34,36). Furthermore, research respondents are less likely to pity persons with mental illness, instead reacting to psychiatric disability with anger and believing that help is not deserved (35,36,39).Understanding the impact of stigma on people with mental illness.
