Individuals with mental illness can experience stigma and discrimination, which can cause adverse consequences (Zerger et al., 2014). Mental illness stigma and discrimination can also intersect with other marginalized social identities that individuals may possess, resulting in unique outcomes for individuals. Unfortunately, the research in this area is somewhat limited, often assumes an additive effect, and does not always consider less visible or more invisible marginalized identities (Turan et al., 2019; Williamson et al., 2017). The additive effect does not take into account the individual’s particular social context, such as elements of privilege, disadvantage, resiliency, which can impact the individual’s experiences (Mizock & Russinova, 2015). There is a need to better capture the experiences of people who face multiple stigmas, which could also help develop more effective mental health interventions (Oexle et al., 2018). This chapter will synthesize the literature in this area on mental illness stigma among various intersecting stigmatized groups, provide a critique of the current literature, and present implications for future treatment and research.
