Trends in Public Stigma of Mental Illness in the US, 1996-2018

Abstract

IMPORTANCE Stigma, the prejudice and discrimination attached to mental illness, has been persistent, interfering with help-seeking, recovery, treatment resources, workforce development, and societal productivity in individuals with mental illness. However, studies assessing changes in public perceptions of mental illness have been limited. OBJECTIVETo evaluate the nature, direction, and magnitude of population-based changes in US mental illness stigma over 22 years. DESIGN, SETTING, AND PARTICIPANTS This survey study used data collected from the US National Stigma Studies, face-to-face interviews conducted as 1996, 2006, and 2018 General Social Survey modules of community-dwelling adults, based on nationally representative, multistage sampling techniques. Individuals aged 18 years or older, including Spanish-speaking respondents, living in noninstitutionalized settings were interviewed in 1996 (n = 1438), 2006 (n = 1520), and 2018 (n = 1171). The present study was conducted from July 2019 to January 2021. MAIN OUTCOMES AND MEASURES Respondents reacted to 1 of 3 vignettes (schizophrenia, depression, alcohol dependence) meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria or a control case (daily troubles). Measures included beliefs about underlying causes (attributions), perceptions of likely violence (danger to others), and rejection (desire for social distance). RESULTSOf the 4129 individuals interviewed in the surveys, 2255 were women (54.6%); mean (SD) age was 44.6 (16.9) years. In the earlier period (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006), respondents endorsing scientific attributions (eg, genetics) for schizophrenia (11.8%), depression (13.0%), and alcohol dependence (10.9%) increased. In the later period (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018), the desire for social distance decreased for depression in work (18.1%), socializing (16.7%), friendship (9.7%), family marriage (14.3%), and group home (10.4%). Inconsistent, sometimes regressive change was observed, particularly regarding dangerousness for schizophrenia (1996-2018: 15.7% increase, P = .001) and bad character for alcohol dependence (1996-2018: 18.2% increase, P = .001). Subgroup differences, defined by race and ethnicity, sex, and educational level, were few and inconsistent. Change appeared to be consistent with age and generational shifts among 2 birth cohorts (1937-1946 and 1987-2000). CONCLUSIONS AND RELEVANCETo date, this survey study found the first evidence of significant decreases in public stigma toward depression. The findings of this study suggest that individuals' age was a conservatizing factor whereas being in the pre-World War II or millennial birth cohorts was a progressive factor. However, stagnant stigma levels for other disorders and increasing public perceptions of likely violence among persons with schizophrenia call for rethinking stigma and retooling reduction strategies to increase service use, improve treatment resources, and...

Altering the landscape of mental illness stigma on university campuses.

“…Students in the sample had a moderately high and high endorsement of persons with a mental illness diagnosis’ dangerousness to others (31%) and to oneself (75%), respectively. The stigma endorsement found in our sample may be attributed to the higher representation of students who have previously engaged in treatment, the use of stigma measures that were nonspecific to mental illness condition, or the real occurrence of lower stigma endorsement by younger U.S. cohorts (Pescosolido et al, 2021). While we were unable to assess these issues in our study, future studies of the concurrent representation of these seven public stigma dimensions and their components on university campuses should take them into account…”

The efficacy of interventions on cognitive, behavioral, and affective public stigma around mental illness: A systematic meta-analytic review.

“…This is consistent with a systematic review of school-based stigma interventions which concluded that there is insufficient evidence to suggest that such interventions are efficacious for school-age (i.e., younger) populations (Mellor, 2014). Interestingly, recent evidence indicates a pattern of decline in behavioral stigma around depression in the United States, and that the effect is attributable to younger and more liberal residents (Pescosolido et al, 2021). Future interventions might consider ways to capitalize on the lower baseline stigma that may be found in younger generations.…”

Stigma towards People with Mental Illness among Portuguese Nursing Students

“…The knowledge and attitude of the general public towards people with mental illness differs depending on the type of illness. For example, several studies described a higher propensity for people to maintain a greater social distance from a person with schizophrenia when compared with someone with an anxiety disorder or depression [ 4 , 5 , 6 ]. This tendency was also verified in a study that compared physicians’ attitudes towards people with schizophrenia and depression [ 7 ].…”
