Journal of Social and Clinical Psychology 30(4): 329-360 Implicit inversion theory suggests that stereotypes about gay men include beliefs that they possess certain mental health traits more characteristic of women than men. However, no research has explored gay men’s stereotype about their own mental health or how their self-stereotype relates to stereotypes of women (i.e., heterosexual women and lesbians). Three studies documented gay men’s self-stereotype about mental health and compared it to other stereotypes. Comparisons among stereotypes about gay men, heterosexual women, and lesbians suggested that the stereotype about gay men partially overlaps with the stereotypes about heterosexual women and lesbians but also has traits independent of those female stereotypes. Overall, there appears to be a prevalent stereotype about gay men’s mental health that is partially explained by the implicit inversion theory.
