Community member attitudes and understanding of "serious mental illness": A mixed-method study.

Abstract

"Serious mental illness" (SMI) is a priority population within mental health treatment and policy. However, there is no standard operational definition across research, clinical, and policy contexts. The use of the label has also not been evaluated regarding its association with stigma among the general public. This mixed-method study compared community members' stigma toward "SMI" with other psychiatric labels and examined community understanding and perceptions of the SMI label. Two hundred forty-six participants recruited via Prolific read randomly manipulated vignettes describing an individual diagnosed with depression, schizophrenia, or "SMI" and completed measures of stigma and qualitative questions regarding familiarity, understanding, and perceived utility of SMI. Quantitative analyses evaluated stigma across vignettes, and qualitative analyses identified common themes across responses. Stigma was relatively high across vignettes, with more negative views reported toward SMI and schizophrenia compared with depression. Quantitative differences in stigma by vignette were not significant after controlling for participants' age and gender. Qualitative responses were split regarding the perceived utility of the SMI term, with noted concerns including its broadness and potential for stigma. Most participants described functional impairment or disability as characteristic of "SMI," and approximately 70% associated schizophrenia and psychotic disorders with "SMI" compared with 45% for depression. Person-level factors were more strongly associated with stigma than psychiatric labels. However, our sample described concerns that the SMI term is vague and may exacerbate stigma. Community education and antistigma efforts should move beyond diagnostic labels in characterizing mental illness to facilitate change in attitudes.
