This paper examines the diversity issues confronting lesbian, gay, and bisexual (LGB) individuals in the 21st century. Beginning with a historical overview of how homosexuality and bisexuality were once classified as mental illness, the paper traces the evolution of psychological and professional understanding since Evelyn Hooker's landmark 1957 research. It discusses how LGB individuals who also belong to racial or ethnic minorities, as well as those at different life stages — from adolescence to old age — face compounded stressors. The paper also considers the particular challenges faced by bisexual individuals and those living with physical disabilities, before evaluating the breadth and limitations of existing research literature.
The paper employs intersectionality as an organizing analytical framework, showing how LGB individuals face layered and compounding forms of prejudice when sexual orientation intersects with race, age, or disability. This approach moves beyond a single-axis view of discrimination and reflects nuanced social science reasoning.
The paper opens with a brief framing statement before moving into a historical introduction covering the reclassification of homosexuality. The background section reviews the psychological literature, followed by the paper's central analytical section, which addresses diversity challenges across subgroups. A definitions section clarifies key terms used throughout, and a concluding evaluation assesses the state and limitations of existing research. A full bibliography closes the paper.
The 21st century has brought new and greater understanding of issues surrounding diversity as it pertains to lesbian, gay, and bisexual people. In the past, it was widely assumed that homosexuality represented a deviant manifestation of some form of mental illness. It was not until the late 1950s (Hooker, 1957) that this idea began to be seriously questioned and the lifestyle subjected to closer academic study. The purpose of this paper is to review issues surrounding the homosexual, lesbian, and bisexual lifestyle, to identify the general nature of that lifestyle as it exists today, and to examine the state of diversity issues as they pertain to this group.
For many years, homosexuality, lesbianism, and bisexuality were classified as mental illness. Evelyn Hooker (1957) was among the first researchers to conduct in-depth studies in this area, finding no significant difference between homosexual and heterosexual men in terms of cognitive abilities or on projective testing. The definitive study by Fox (1996) was one of the first to state conclusively that there was no evidence of psychopathology in studies of bisexuals that could be attributed solely to their sexuality. Despite these findings, lesbian, gay, and bisexual (LGB) individuals continue to suffer from prejudice and discrimination as strong as that related to race, religion, or ethnic background. In some cases, individuals must navigate multiple, overlapping forms of discrimination, effectively making them members of multiple minority groups.
While some differences do exist in the psychological functioning of homosexual, lesbian, and bisexual men and women, research consistently links these differences to stress related to the lifestyle rather than to sexuality itself. These stress-related outcomes include diminished self-esteem, increased rates of suicide attempts, and substance abuse — all largely attributable to the emotional distress caused by social stigmatization (Gonsiorek, 1991).
Much debate has surrounded the question of whether homosexuality is a choice or a predetermined behavioral pattern. Much of the literature that continues to classify homosexuality and bisexuality within the framework of mental illness appears to be scientifically unsound, exhibiting methodological errors, flawed group comparisons, poor sampling procedures, and a general lack of empirical support for the association of gay, lesbian, or bisexual identity with mental illness.
To date, all major mental health associations have disavowed such studies. The American Psychological Association issued a landmark statement in 1975 urging mental health professionals to treat homosexual and bisexual patients not with the aim of changing their sexuality, but rather to help them explore the sources of distress they experienced while affirming what the patients understood to be their true sexual identity. The ethical code governing psychologists includes a statement affirming this position, specifying that there should be no discrimination against homosexuals on the basis of lifestyle.
