Exploring the relationship between gay men's selfand meta-stereotype endorsement with well-being and self-worth Stereotypes typically have negative impacts on stigmatized minority groups, especially when endorsed by members of that group. This paper examines the prevalence and consequences of stereotype endorsement on well-being within the gay community.Specifically, we explored how gay men's self-stereotype (i.e., personal beliefs about the stereotypes pertaining to one's in-group) and meta-stereotype (i.e., believing that out-group members endorse stereotypes pertaining to one's in-group) endorsement would be related to mental and cognitive well-being. The sample of 253 gay male participants (aged 18 -78 years; M = 38.25, SD = 13.51) completed an online questionnaire assessing demographics, self-and meta-stereotype endorsement, mental well-being (depression, anxiety, stress), and cognitive well-being (life satisfaction, self-worth) measures. We found evidence that our sample endorsed both self-and meta-stereotypes, with meta-stereotypes being endorsed more strongly than self-stereotypes. Regression analyses revealed a unique pattern of findings about the consequences of endorsing stereotypes: increases in self-stereotyping predicted decreases in mental well-being, whereas increases in meta-stereotyping predicted decreases in cognitive well-being. Limitations and future directions are discussed.
