Guided by theory on stigma, a Likert‐type scale was developed to measure 7 factors of attitudes toward people with mental illness: interpersonal anxiety, relationship disruption, poor hygiene, visibility, treatability, professional efficacy, and recovery. The scale was validated among college students and community members, measuring attitudes toward people with mental illness, depression, bipolar disorder, and schizophrenia. In a second application, college students completed the scale from their own perspective, then from an imagined perspective of someone with mental illness, while psychiatric patients completed the scale from their own perspective, then from an imagined viewpoint of someone without mental illness. Psychiatric patients assumed that they were stigmatized to a greater extent than was admitted by the student sample.
