HIV-related stigma and knowledge in the United States: prevalence and trends, 1991-1999.

OBJECTIVES This study assessed the prevalence of AIDS stigma and misinformation about HIV transmission in 1997 and 1999 and examined trends in stigma in the United States during the 1990s. METHODS Telephone surveys with national probability samples of English-speaking adults were conducted in the period 1996 to 1997 (n = 1309) and in 1998 to 1999 (n = 669). Findings were compared with results from a similar 1991 survey. RESULTS Overt expressions of stigma declined throughout the 1990s, with support for its most extreme and coercive forms (e.g., quarantine) at very low levels by 1999. However, inaccurate beliefs about the risks posed by casual social contact increased, as did the belief that people with AIDS (PWAs) deserve their illness. In 1999, approximately one third of respondents expressed discomfort and negative feelings toward PWAs. CONCLUSION Although support for extremely punitive policies toward PWAs has declined, AIDS remains a stigmatized condition in the United States. The persistence of discomfort with PWAs, blame directed at PWAs for their condition, and misapprehensions about casual social contact are cause for continuing concern and should be addressed in HIV prevention and education programs.

Some of My Best Friends Intergroup Contact, Concealable Stigma, and Heterosexuals' Attitudes Toward Gay Men and Lesbians

In a two-wave national telephone survey, a probability sample of English-speaking adults indicated their attitudes toward gay men at Wave 1 (1990-91; n = 538) and toward both gay men and lesbians approximately 1 year later (n = 382 at Wave 2). At Wave 1, heterosexuals reporting interpersonal contact (31.3%) manifested more positive attitudes toward gay men than those without contact. Their attitudes were more favorable to the extent that they reported more relationships, closer relationships, and receiving direct disclosure about anothers homosexuality. At Wave 2, these findings were generally replicated for attitudes toward lesbians as well as gay men. Cross-wave analyses suggest a reciprocal relationship between contact and attitudes. Theoretical and policy implications of the results are discussed, with special attention to the role of interpersonal disclosure in reducing stigma based on a concealable status.

Black heterosexuals’ attitudes toward lesbians and gay men in the United States

Although the direction and intensity of Black heterosexuals’ attitudes toward homosexuality have been topics for considerable speculation, empirical data from representative samples previously have not been available. In the current article we report findings from a two‐wave telephone survey with a national probability sample of 391 Black heterosexual adults. Results indicated that negative attitudes toward homosexuality are widespread but do not appear to be more prevalent among Blacks than among Whites. Gender differences in Black heterosexuals’ attitudes (mens attitudes toward gay men were more negative than their attitudes toward lesbians or womens attitudes toward gay men) appeared to result primarily from mens greater tendency to regard male homosexuality as unnatural. The single most important predictor of attitudes was the attribution of choice to sexual orientation: Respondents who believed that homosexuality is beyond an individuals control expressed significantly more favorable attitudes to...

AIDS Stigma and Sexual Prejudice

This article presents national survey data to assess the extent to which AIDS-related stigma remains linked to public attitudes toward homosexuality in the United States. Most heterosexuals continue to associate AIDS primarily with homosexuality or bisexuality, and this association is correlated with higher levels of sexual prejudice (antigay attitudes). Although all people who contract AIDS sexually are assigned blame for their infection, such blame is greater for a gay or bisexual man than for a heterosexual man or woman. A sizable minority of the public equates all male-male sexual behavior with AIDS, even sex between two HIV-negative men. A substantial portion also expresses discomfort about touching an article of clothing or drinking from a sterilized glass used by a person with AIDS (PWA). These misconceptions and discomfort are correlated with sexual prejudice. It is argued that the link between AIDS attitudes and sexual prejudice impedes HIV prevention efforts and threatens civil rights.

Public reactions to AIDS in the United States: a second decade of stigma.

The pervasiveness of stigma in the United States related to the acquired immunodeficiency syndrome (AIDS) was assessed in telephone interviews with a general adult sample (n = 538) and an African-American sample (n = 607). Most respondents manifested at least some stigma. African Americans expressed greater support for policies separating persons with AIDS from others and a stronger desire to avoid these persons, whereas Whites expressed more negative feelings toward them and a greater willingness to blame them for their illness. Regardless of race, men were more likely than women to support policies such as quarantine and to say that they would avoid persons with AIDS.

Increased social fear and decreased fear of objects in monkeys with neonatal amygdala lesions.

The amygdala has been implicated in the mediation of emotional and species-specific social behavior (Kling et al., 1970; Kling and Brothers, 1992; Kluver and Bucy, 1939; Rosvold et al., 1954). Humans with bilateral amygdala damage are impaired in judging negative emotion in facial expressions and making accurate judgements of trustworthiness (Adolphs et al., 1998, 1994). Amygdala dysfunction has also been implicated in human disorders ranging from social anxiety (Birbaumer et al., 1998) to depression (Drevets, 2000) to autism (Bachevalier, 1994; Baron-Cohen et al., 2000; Bauman and Kemper, 1993). We produced selective amygdala lesions in 2-week-old macaque monkeys who were returned to their mothers for rearing. At 6-8 months of age, the lesioned animals demonstrated less fear of novel objects such as rubber snakes than age-matched controls. However, they displayed substantially more fear behavior than controls during dyadic social interactions. These results suggest that neonatal amygdala lesions dissociate a system that mediates social fear from one that mediates fear of inanimate objects. Furthermore, much of the age-appropriate repertoire of social behavior was present in amygdala-lesioned infants indicating that these lesions do not produce autistic-like behavior in monkeys. Finally, amygdala lesions early in development have different effects on social behavior than lesions produced in adulthood.

Stigma, social risk, and health policy: Public attitudes toward HIV surveillance policies and the social construction of illness

Data from a 1999 national telephone survey with a probability sample of English-speaking US adults (N=1,335) were used to assess how support for HIV surveillance policies is related to AIDS stigma and negative attitudes toward groups disproportionately affected by the epidemic. Anonymous reporting of HIV results to the government was supported by a margin of approximately 2-to-l, but name-based reporting was opposed 3-to-l. Compared with other respondents, supporters of name-based surveillance expressed significantly more negative feelings toward people with AIDS, gay men, lesbians, and injecting drug users. More than one third of all respondents reported that concerns about AIDS stigma would affect their own decision to be tested for HIV in the future. Implications for understanding the social construction of illness and for implementing effective HIV surveillance programs are discussed.

The effects of bilateral lesions of the amygdala on dyadic social interactions in rhesus monkeys (Macaca mulatta)

The role of the amygdala in dyadic social interactions of adult rhesus monkeys (Macaca mulatta) was assessed after bilateral ibotenic acid lesions. Social, nonsocial, and spatial behaviors of amygdalectomized and control monkeys were assessed in 3 dyadic experiments: constrained, unconstrained, and round robin. Lesions produced extensive bilateral damage to the amygdala. Across all experiments, the amygdalectomized monkeys demonstrated increased social affiliation, decreased anxiety, and increased confidence compared with control monkeys, particularly during early encounters. Normal subjects also demonstrated increased social affiliation toward the amygdalectomized subjects. These results indicate that amygdala lesions in adult monkeys lead to a decrease in the species-normal reluctance to immediately engage a novel conspecific in social behavior. The altered behavior of the amygdalectomized monkeys may have induced the increased social interactions from their normal companions. This is contrary to the idea that amygdalectomy produces a decrease in social interaction and increased aggression from conspecifics.

Sex differences in how heterosexuals think about lesbians and gay men: Evidence from survey context effects

Two experiments were embedded in a 1997 telephone survey of U.S. households to assess possible differences in how heterosexuals think about lesbians versus gay men. In each experiment, one half of the sample first responded to one or more attitude items about lesbians, followed by comparable items about gay men. The other half received the gay male item(s) first. Results are reported separately for White (N = 976) and Black (N = 479) heterosexuals. For White and Black men alike, self‐reported attitudes toward lesbians tended to be more favorable when they were assessed without reference to gay men (i.e., lesbian items presented first). White mens reactions to gay men tended to be less negative when assessed after the questions about lesbians were presented, but Black mens responses did not consistently show this pattern. For some items, women gave more favorable ratings of lesbians and less favorable ratings of gay men when the lesbian items were presented first. The findings suggest possible gender dif...

Why primate models matter

Research involving nonhuman primates (NHPs) has played a vital role in many of the medical and scientific advances of the past century. NHPs are used because of their similarity to humans in physiology, neuroanatomy, reproduction, development, cognition, and social complexity—yet it is these very similarities that make the use of NHPs in biomedical research a considered decision. As primate researchers, we feel an obligation and responsibility to present the facts concerning why primates are used in various areas of biomedical research. Recent decisions in the United States, including the phasing out of chimpanzees in research by the National Institutes of Health and the pending closure of the New England Primate Research Center, illustrate to us the critical importance of conveying why continued research with primates is needed. Here, we review key areas in biomedicine where primate models have been, and continue to be, essential for advancing fundamental knowledge in biomedical and biological research. Am. J.
