Research on Sexual and Gender Minority Health: Historical Developments and Future Directions

In this article the author reviews research evidence on the prevalence of mental disorders in lesbians, gay men, and bisexuals (LGBs) and shows, using meta-analyses, that LGBs have a higher prevalence of mental disorders than heterosexuals. The author offers a conceptual framework for understanding this excess in prevalence of disorder in terms of minority stress--explaining that stigma, prejudice, and discrimination create a hostile and stressful social environment that causes mental health problems. The model describes stress processes, including the experience of prejudice events, expectations of rejection, hiding and concealing, internalized homophobia, and ameliorative coping processes. This conceptual framework is the basis for the review of research evidence, suggestions for future research directions, and exploration of public policy implications.

This study describes stress as derived from minority status and explores its effect on psychological distress in gay men. The concept of minority stress is based on the premise that gay people in a heterosexist society are subjected to chronic stress related to their stigmatization. Minority stressors were conceptualized as: internalized homophobia, which relates to gay men's direction of societal negative attitudes toward the self; stigma, which relates to expectations of rejection and discrimination; and actual experiences of discrimination and violence. The mental health effects of the three minority stressors were tested in a community sample of 741 New York City gay men. The results supported minority stress hypotheses: each of the stressors had a significant independent association with a variety of mental health measures. Odds ratios suggested that men who had high levels of minority stress were twice to three times as likely to suffer also from high levels of distress.

Recent estimates of mental health morbidity among adults reporting same-gender sexual partners suggest that lesbians, gay men, and bisexual individuals may experience excess risk for some mental disorders as compared with heterosexual individuals. However, sexual orientation has not been measured directly. Using data from a nationally representative survey of 2,917 midlife adults, the authors examined possible sexual orientation-related differences in morbidity, distress, and mental health services use. Results indicate that gay-bisexual men evidenced higher prevalence of depression, panic attacks, and psychological distress than heterosexual men. Lesbian-bisexual women showed greater prevalence of generalized anxiety disorder than heterosexual women. Services use was more frequent among those of minority sexual orientation. Findings support the existence of sexual orientation differences in patterns of morbidity and treatment use.
