Is Essentialism Essential? Reducing Homonegative Prejudice by Targeting Diverse Sexual Orientation Beliefs

Etiology Beliefs About Sexual and Gender Minority Youth (EB-SGM): Validation with College Students, Community Adults, and Pediatric Healthcare Providers

Sexual and gender minority (SGM) youth are at risk for adverse health outcomes because of stigma and discrimination exposure. Individuals' beliefs about the biological origin of SGM identity are linked to their negative attitudes and biases against SGM populations, which can also apply to pediatric healthcare providers. The current study outlines validation of the Etiology Beliefs about Sexual and Gender Minority Youth (EB-SGM) scale, a 12-item measure designed to assess adults' beliefs about youths' biological versus environmental SGM etiology. College students (N = 285; study 1), community adults (N = 258; study 2), and pediatric providers (N = 104; study 3) completed the EB-SGM and other self-report measures. Exploratory factor analysis (EFA) in study 1 revealed a three-factor structure: beliefs about gender nonconforming behavior, beliefs about gender identity, and beliefs about sexual attraction/behavior. Confirmatory factor analysis (CFA) in study 2 suggested a bi-factor structure, which was replicated in study 3. The EB-SGM demonstrated adequate concurrent and discriminant validity. We also examined bivariate correlations between etiology beliefs and sociodemographic characteristics across samples. Findings indicate that EB-SGM is a psychometrically sound instrument to measure adults' etiology beliefs. The EB-SGM has the potential to be used as a screening measure to enhance pediatric healthcare providers' SGM training.

The Role of Sexual Prejudice and Aetiology Beliefs in the Italians' Attitudes Toward Adoption by Same-Sex Couples

Research found that those who believe sexual orientation is inborn have generally positive attitudes toward gay men and lesbian women. However, other studies have also found that these beliefs could include negative eugenic ideas. This study aims to investigate the role of people's beliefs about the aetiology of sexual orientation in attitudes toward adoption for both gay and lesbian couples in Italy. We hypothesized that this relationship would be mediated by sexual prejudice. To test the predictions, 256 Italian heterosexual participants were asked to answer questions on a scale about their beliefs regarding the aetiology of sexual orientation, sexual prejudice, and attitudes toward adoption by same-sex couples. Results confirmed that the relationship between aetiology beliefs and support for adoption by gay and lesbian couples was fully mediated by sexual prejudice. These results suggest that the belief that sexual orientation is controllable may serve to justify one's prejudice and, in turn, result in a lower support for same-sex couples' adoption.

Effects of Biological Determinism on Beliefs and Attitudes About Transgender People: Psychological Essentialism and Biased Assimilation

This experimental study examined the effects of biological attributions on individuals' beliefs and attitudes toward transgender people and the moderating role of right-wing authoritarianism (RWA). We randomly assigned 183 Chinese university students (men: n = 85, women: n = 98) to read one of three fictitious articles. The first article suggested that transgender identity was causally linked to biology (biological determinist condition), the second one highlighted the interplay between biological and environmental factors (epigenetic condition), whereas the third article did not mention the origins of transgender identity (control condition). Consistent with the biased assimilation hypothesis, the effects of biological attributions depended on individual differences in RWA. Low-RWA participants showed higher levels of naturalness and discreteness/homogeneity beliefs about transgender identity in the biological determinist condition than those in the control condition. By contrast, high-RWA participants displayed higher levels of discreteness/homogeneity beliefs but similar levels of naturalness beliefs when they read the biological determinist message compared with the control group. Low-RWA participants showed higher levels of naturalness but similar levels of discreteness/homogeneity beliefs in the epigenetic condition compared with the control, whereas high-RWA participants exhibited lower levels of naturalness and higher levels of discreteness/homogeneity beliefs when they read the epigenetic message compared with the control group. This study also suggests that, contrary to attribution theory, presenting information regarding the biological basis of transgender identity does not necessarily lead to more positive attitudes because (a) it triggers essentialist thinking and (b) the effects of biological attributions depend on recipients' authoritarian dispositions.

North American Undergraduate Students' Sexual Orientation Beliefs: Exploring Differences across Diverse Sexual and Gender Identities

Societal beliefs about various aspects of sexual orientation have been shown to influence whether people have discriminatory or supportive attitudes toward diverse sexual orientations. The overall aim of this study is to measure the beliefs about sexual orientation among a diverse sample of university students from two institutions in Canada and the United States of America. Specifically, we explored how beliefs varied among individuals with differing sexual orientations and gender identities, while controlling for cultural differences. A total of 475 participants completed an online survey comprising of the Sexual Orientations Beliefs Scale (SOBS). ANCOVAs revealed that sexual orientation was a significant factor for all four subscales of the SOBS (naturalness, homogeneity, informativeness, and discreteness). Sexual orientation was the most significant predictor of endorsing different sexual orientation beliefs. We found a significant interaction between gender and sexual orientation, revealing that perceptions of sexual orientation differ between straight-identified men and straight women.

Assessing the Effects of a Real-Life Contact Intervention on Prejudice Toward LGBT People

Prejudice against sexual and gender minorities (e.g., LGBT people) is quite prevalent and is harmful. We examined an existing-and often-used-contact intervention in pre-existing groups in an educational setting and assessed its effectiveness in reducing different forms of LGBT negativity. We focused particularly on modern LGBT negativity: a relatively subtle form of prejudice, involving ambivalence, denial, and/or the belief that there is too much attention for LGBT prejudice. We used a mixed design in which condition (experimental vs. control group) was the between-participants factor, which was randomized at the group level, and time (pretest vs. posttest vs. follow-up) was the within-participants factor (N = 117). Interventions were video recorded and the behavior of LGBT educators and participants was coded. Participants responded positively to the intervention, especially to the LGBT educator's "coming-out story." Exploratory analysis of the video data indicated that the perceived effectiveness of the intervention was higher in groups where participants were more engaged, although caution is necessary in interpreting this finding. The most important measure indicated that modern LGBT negativity decreased in the intervention groups directly after the intervention, but returned to baseline levels one week later. However, in the control condition, modern LGBT negativity had increased over time. Taken together, this suggests that an actual reduction in modern LGBT negativity was short-lived (i.e., the intervention effect disappeared within 7 days).

Sexual Orientation Beliefs and Identity Development: A Person-Centered Analysis among Sexual Minorities

We conducted person-centered analysis of sexual orientation beliefs among sexual minorities to explore potential relationships between these beliefs and sexual orientation, developmental milestones, race and ethnicity, and attitudes about sexual orientation. We recruited participants (N = 416) via Amazon Mechanical Turk who completed measures of beliefs about sexual orientation and attitudes about their own sexuality, as well as assessments of mental health and age of sexual identity development milestones. We conducted a latent profile analysis and found three distinct sexual orientation belief profiles, similar to those previously observed in predominantly straight samples. We found that sexual orientation and race-ethnicity predicted belief profile membership, with the latter exhibiting the most substantial effect. Of the four identity developmental milestones tested, only the age of first same-sex attraction predicted belief profile membership. Across profiles, members differed significantly in their mean endorsement of both positive and negative attitudes regarding sexual orientation and psychological distress. Thus, the current research suggests that sexual orientation beliefs are powerful constructs in the lives of sexual minorities, with relationships to sexual orientation, other social identities, and mental health.
