The relationships between perceived mental illness prevalence, mental illness stigma, and attitudes toward...

Previous research suggests that, despite the commonality of mental illness in the United States, the majority of U.S. individuals with mental illness do not seek treatment. One important factor that contributes to this lack of treatment utilization is mental illness stigma. Such stigma may result, in part, from many individuals in the U.S. underestimating the prevalence of mental illness. To test whether this is the case, 638 adults from across the U.S. completed measures related to perceived prevalence of mental illness, private stigma, perceived public stigma, and help-seeking. Findings indicated participants significantly underestimated the given-year prevalence rate of mental illness. The perceived given-year prevalence rate was significantly correlated with lower private stigma and more positive attitudes towards help-seeking. Personal stigma significantly predicted attitudes towards help-seeking. Findings also suggested that individuals who have received mental health services have a higher perceived prevalence rate of mental illness, as well as lower levels of personal stigma and more positive attitudes towards help-seeking. These findings support the notion that helping the general public recognize the true prevalence rate of mental illness could reduce personal mental illness stigma and facilitate help-seeking behaviors. However, future experimental studies are needed to test this hypothesis.
