Attitudes about mental illness and its treatment: validation of a generic scale for public health surveillance of mental illness associated stigma.

The purpose of this study was to test a brief instrument to monitor the U.S. public's attitudes about mental illness. A SAMHSA and CDC-led panel reached consensus through an iterative process to identify generic, multidimensional measures to test using a representative sample of 5,251 adults. Exploratory factor analysis revealed two subscales (Negative Stereotypes [alpha = 0.66]; Recovery and Outcomes [alpha = 0.69]). Confirmatory factor analysis supported the convergent validity of the two subscales. Subscale scores differed by sex, race/ethnicity, and experience with mental illness. Inclusion of these brief subscales on existing population-based surveys can help states and others track attitudes about mental illness.
