Stigma salience increases loneliness among ethnic minorities.

Research shows that ethnic minorities are at increased risk of loneliness compared to the general population of the United Kingdom. We hypothesized that stigma salience increases loneliness among ethnic minorities, conducting two experimental studies with ethnic minorities (Study 1: N = 134, Study 2: N = 267) in which participants were randomly assigned to a stigma salience (recalling a personal experience of discrimination based on ethnicity) or control condition (recalling a past meal in Study 1 and the experience of reading a book in Study 2). Across these two studies, we demonstrated that stigma salience consistently increased self-reported loneliness relative to the control conditions. Study 1 additionally showed evidence for an indirect effect of stigma salience on loneliness through feelings of anxiety. Study 2 replicated the effect of self-relevant (but not non-self-relevant) stigma salience on loneliness and provided suggestive evidence for a more specific indirect effect through identity-related social anxiety.
