Mostly heterosexual as a distinct sexual orientation group: A systematic review of the empirical evidence

Attitude Is Everything: Examining Acceptance of Violence Items for Differential Item Functioning Across Heterosexual and Sexual Minority Youth

Acceptance of dating violence (ADV) is a cognitive risk factor for violence perpetration and a common target of prevention programs. However, frequently used items assessing ADV are characterized by heteronormative item wording, and limited research has evaluated the degree to which ADV items function equivalently for both heterosexual and sexual minority youth (SMY). The current study sought to determine if there are differences in the way heterosexual and SMY respond to ADV survey items. Secondary data from a total of 2,014 adolescents (Mage = 16.78) were used to examine differences in ADV. Results of differential item functioning analysis indicated nonuniform differential item functioning for two of eight ADV items, with heterosexual youth being more likely to express strong levels of agreements with (a) female-perpetrated physical violence in response to male-perpetrated violence and (b) female-perpetrated violence against males broadly, relative to SMY. Although these differences were of negligible magnitude and only resulted in minimal differences in overall expected average scores, heterosexual youth were more likely to strongly accept female-perpetrated dating violence compared to SMY. Findings highlight differences in ADV item response patterns across heterosexual and sexual minority identifying youth and provide preliminary evidence for group differences in acceptance of female-perpetrated dating violence. Implications for prevention programming based on current findings include greater focus on measure adaptation and development as well as more consensus on the necessity of preventing female-perpetrated violence.

Fixed or Fluid? Sexual Identity Fluidity in a Large National Panel Study of New Zealand Adults

Sexual orientation has been defined as an enduring aspect of the self, but emerging evidence reveals that people's sexual attractions, behaviors, and identities can shift over time. To examine this possibility, we present a large longitudinal analysis of sexual orientation identity fluidity among New Zealand adults (Ntotal = 45,856; age = 18-99; lesbian, gay, bisexual, and other sexual minority (LGB+) ns = 746-3,387). Over seven years, 5.7% of participants changed sexual identities at least once. Change was bi-directional (i.e. toward and away from LGB+ identities) and most common in people who initially reported a plurisexual identity. Although women reported higher rates of plurisexuality than men, they were not more fluid in their identities, contradicting the notion of male fixedness and female plasticity in sexuality. Moreover, openness to experience was associated with increased odds of changing from a heterosexual to a plurisexual identity, while political liberalism and lower conscientiousness were associated with increased odds of changing from a heterosexual to a plurisexual identity and more identity changes over time. Overall, our study shows that sexual identity can be fluid into adulthood and has implications for how we understand contemporary human sexuality.

Laboratory Sex Research: Perceptions of the Ace Community

Asexuality is a sexual orientation centered around low or absent sexual attraction. Despite the growth of empirical scholarship on asexuality, laboratory sex research with asexual individuals remains significantly underutilized. As such, we conducted a qualitative survey aimed at examining asexual individuals' perceptions of laboratory sex research as well as their perspectives/experiences on participation. Reflexive thematic analysis of 412 responses revealed 4 themes and 10 sub-themes focused on mapping the domain of asexuality, participants' trust, distrust and ambivalence toward laboratory sex research, and developing best practices for overcoming challenges with asexual individuals. A large proportion of asexual individuals emphasized concerns related to the potential medicalization and pathologization of asexuality, with 34.6% exhibiting their unwillingness to participate. Nonetheless, 41.7% of asexual individuals expressed a desire to take part in laboratory sexuality studies. These findings indicate a strong interest in laboratory sex research, driven by the lack of knowledge about ace sexual functioning. To further improve ace individuals´ engagement and experience in such studies, a set of participant-driven recommendations was presented. As such, this study highlights the importance of grounding future laboratory sex research with asexual individuals in ethical and reliable procedures.

Mainly heterosexual, bisexual, or other?: The measurement of sexual minority status and its impact on analytic sample, demographic distribution and health outcomes

BACKGROUND

Sexual orientation has been measured in a wide variety of ways which reflect both theoretical and practical considerations. However, choice of sexual orientation measure and recoding strategy can impact analytic sample, as well as demographic and health profiles, in analyses of sexual minority populations. We aimed to examine how choice of sexual orientation dimension and recoding decisions impact estimates in the sexual minority population in two population-based studies in the UK.

METHODS

We used data collected at age 17 (2018) in the UK Millennium Cohort Study and at sweep six (2012-13) and eight (2017-18) of the English Longitudinal Study of Ageing. Descriptive statistics were used to examine the impact of choice of sexual orientation dimension (i.e. identity, attraction and experience) and recoding decisions on achieved analytic sample and composition by selected demographic and health measures within and between datasets.

RESULTS

Dimension choice and recoding decisions resulted in variation in analytic sample. For example, more respondents reported some same-sex sexual attraction than reported a non-heterosexual identity (adolescents: 20.77% vs 8.97%, older adults: 4.77% vs 1.04%). Demographic distributions varied, but not substantially by dimension choice or recoding strategy. Overall, in both datasets sexual minority respondents were more likely to be White and in the highest quintiles for income and education than heterosexual respondents. Health status did not vary substantially by dimension choice or recoding strategy, however sexual minority respondents reported worse health than their heterosexual peers.

CONCLUSIONS

This study explores a range of practical and theoretical considerations when analysing sexual minority respondents using survey data. We highlight the impact recoding decisions may have on the numbers of sexual minority respondents identified within a dataset and demographic and health distributions in this understudied population. We also demonstrate the benefits of including multiple dimensions for capturing mechanisms of interest in elucidating ambiguous responses and exploring sexual diversity.

Sexual orientation disparities in gestational diabetes and hypertensive disorders of pregnancy

BACKGROUND

Sexual minority (SM) individuals (e.g., those with same-sex attractions/partners or who identify as lesbian/gay/bisexual) experience a host of physical and mental health disparities. However, little is known about sexual orientation-related disparities in gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP; gestational hypertension [gHTN] and preeclampsia).

OBJECTIVE

To estimate disparities in GDM, gHTN and preeclampsia by sexual orientation.

METHODS

We used data from the Nurses' Health Study II-a cohort of nurses across the US enrolled in 1989 at 25-42 years of age-restricted to those with pregnancies ≥20 weeks gestation and non-missing sexual orientation data (63,518 participants; 146,079 pregnancies). Our primary outcomes were GDM, gHTN and preeclampsia, which participants reported for each of their pregnancies. Participants also reported their sexual orientation identity and same-sex attractions/partners. We compared the risk of each outcome in pregnancies among heterosexual participants with no same-sex experience (reference) to those among SM participants overall and within subgroups: (1) heterosexual with same-sex experience, (2) mostly heterosexual, (3) bisexual and (4) lesbian/gay participants. We used modified Poisson models to estimate risk ratios (RR) and 95% confidence intervals (CI), fit via weighted generalised estimating equations, to account for multiple pregnancies per person over time and informative cluster sizes.

RESULTS

The overall prevalence of each outcome was ≤5%. Mostly heterosexual participants had a 31% higher risk of gHTN (RR 1.31, 95% CI 1.03, 1.66), and heterosexual participants with same-sex experience had a 31% higher risk of GDM (RR 1.31, 95% CI 1.13, 1.50), compared to heterosexual participants with no same-sex experience. The magnitudes of the risk ratios were high among bisexual participants for gHTN and preeclampsia and among lesbian/gay participants for gHTN.

CONCLUSIONS

Some SM groups may be disparately burdened by GDM and HDP. Elucidating modifiable mechanisms (e.g., structural barriers, discrimination) for reducing adverse pregnancy outcomes among SM populations is critical.

The role of romantic relationships for sexual minority young adults' depressive symptoms: Does relationship type matter?

Sexual minority young adults consistently report higher rates of depression than heterosexual young adults. Drawing on the National Longitudinal Study of Adolescent to Adult Health, this study examines if types of romantic relationships provide mental health benefits for lesbian, gay, and bisexual young adults. Further, analyses distinguish between same- and different-sex unions to help determine which relationship types offer the most mental health benefits. The results show that marriage is linked to fewer depressive symptoms for gay and lesbian young adults, compared to being unpartnered or in a dating relationship. Further, same-sex unions are associated with fewer depressive symptoms, but not different-sex unions. Yet, bisexual respondents' depressive symptoms are not associated with romantic relationships, regardless of relationship type. The results suggest that it is important to address the stigma surrounding sexual minority status and same-sex relationships to improve the burden of depressive symptoms on sexual minority young adults.

Sex and Sexual Orientation Differences in Dark Triad Traits, Sexual Excitation/Inhibition, and Sociosexuality

The present study sought to investigate sex and sexual orientation differences in several traits related to sexuality and sexual behavior. Examining sexual orientation differences alongside basic sex differences to help identify correlates of sexual orientation diversity, and whether individuals with varying degrees of same-sex attraction show concurrent sex-atypical shifts in other domains. Males tend to score higher than females in the Dark Triad (DT) traits of sub-clinical narcissism, psychopathy, and Machiavellianism. Similarly, females tend to be more cautious than males in their attitudes and desires toward casual sex activity (i.e., sociosexuality). These sex differences may be related to the propensity for individuals to become easily sexually excited, which is higher in males, or to instead inhibit sexual arousal, which is higher in females. In a large undergraduate sample (N = 2047), we replicated expected sex differences in DT traits, sociosexuality, and sexual excitation/inhibition. We found that non-heterosexual females were "male-shifted" in some of these traits, but these shifts tended to be strongest among mostly heterosexual and bisexual individuals. Furthermore, we found that within-sex variation in sociosexuality, sexual excitation, and sexual inhibition was not related to sexual orientation in a linear fashion. Instead, sociosexuality and sexual excitation were related to sexual orientation in a curvilinear (inverted-U) fashion, especially among females. The fact that traits correlated with bisexuality and homosexuality were somewhat distinct is consistent with the idea that different developmental pathways may lead to these discrete sexual attraction patterns.

Differences in medically assisted reproduction use by sexual identity and partnership: a prospective cohort of cisgender women

STUDY QUESTION

Does medically assisted reproduction (MAR) use among cisgender women differ among those with same-sex partners or lesbian/bisexual identities compared to peers with different-sex partners or heterosexual identities?

SUMMARY ANSWER

Women with same-sex partners or lesbian/bisexual identities are more likely to utilize any MAR but are no more likely to use ART (i.e. IVF, reciprocal IVF, embryo transfer, unspecified ART, ICSI, and gamete or zygote intrafallopian transfer) compared to non-ART MAR (i.e. IUI, ovulation induction, and intravaginal or intracervical insemination) than their different-sex partnered and completely heterosexual peers.

WHAT IS KNOWN ALREADY

Sexual minority women (SMW) form families in myriad ways, including through fostering, adoption, genetic, and/or biological routes. Emerging evidence suggests this population increasingly wants to form genetic and/or biological families, yet little is known about their family formation processes and conception needs.

STUDY DESIGN, SIZE, DURATION

The Growing Up Today Study is a US-based prospective cohort (n = 27 805). Participants were 9-17 years of age at enrollment (1996 and 2004). Biennial follow-up is ongoing, with data collected through 2021.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Cisgender women who met the following criteria were included in this sample: endorsed ever being pregnant; attempted a pregnancy in 2019 or 2021; and endorsed either a male- or female-sex partner OR responded to questions regarding their sexual identity during their conception window. The main outcome was any MAR use including ART (i.e. procedures involving micromanipulation of gametes) and non-ART MAR (i.e. nonmanipulation of gametes). Secondary outcomes included specific MAR procedures, time to conception, and trends across time. We assessed differences in any MAR use using weighted modified Poisson generalized estimating equations.

MAIN RESULTS AND THE ROLE OF CHANCE

Among 3519 participants, there were 6935 pregnancies/pregnancy attempts and 19.4% involved MAR. A total of 47 pregnancies or pregnancy attempts were among the same-sex partnered participants, while 91 were among bisexual participants and 37 among lesbian participants. Participants with same-sex, compared to different-sex partners were almost five times as likely to use MAR (risk ratio [95% CI]: 4.78 [4.06, 5.61]). Compared to completely heterosexual participants, there was greater MAR use among lesbian (4.00 [3.10, 5.16]) and bisexual (2.22 [1.60, 3.07]) participants compared to no MAR use; mostly heterosexual participants were also more likely to use ART (1.42 [1.11, 1.82]) compared to non-ART MAR. Among first pregnancies conceived using MAR, conception pathways differed by partnership and sexual identity groups; differences were largest for IUI, intravaginal insemination, and timed intercourse with ovulation induction. From 2002 to 2021, MAR use increased proportionally to total pregnancies/pregnancy attempts; ART use was increasingly common in later years among same-sex partnered and lesbian participants.

LIMITATIONS, REASONS FOR CAUTION

Our results are limited by the small number of SMW, the homogenous sample of mostly White, educated participants, the potential misclassification of MAR use when creating conception pathways unique to SMW, and the questionnaire's skip logic, which excluded certain participants from receiving MAR questions.

WIDER IMPLICATIONS OF THE FINDINGS

Previous studies on SMW family formation have primarily focused on clinical outcomes from ART procedures and perinatal outcomes by conception method, and have been almost exclusively limited to European, clinical samples that relied on partnership data only. Despite the small sample of SMW within a nonrepresentative study, this is the first study to our knowledge to use a nonclinical sample of cisgender women from across the USA to elucidate family formation pathways by partnership as well as sexual identity, including pathways that may be unique to SMW. This was made possible by our innovative approach to MAR categorization within a large, prospective dataset that collected detailed sexual orientation data. Specifically, lesbian, bisexual, and same-sex partnered participants used both ART and non-ART MAR at similar frequencies compared to heterosexual and different-sex partnered participants. This may signal differential access to conception pathways owing to structural barriers, emerging conception trends as family formation among SMW has increased, and a need for conception support beyond specialized providers and fertility clinics.

Genetic and Environmental Influences on Sexual Orientation: Moderation by Childhood Gender Nonconformity and Early-Life Adversity

Existing evidence indicates genetic and non-genetic influences on sexual orientation; however, the possibility of gene-environment interplay has not been previously formally tested despite theories indicating this. Using a Finnish twin cohort, this study investigated whether childhood gender nonconformity and early-life adversities independently moderated individual differences in sexual orientation and childhood gender nonconformity, the relationship between them, and the etiological bases of the proposed moderation effects. Sexual orientation, childhood gender nonconformity, and early-life adversities were assessed using standard questionnaires. Structural equation twin model fitting was carried out using OpenMx. Childhood gender nonconformity was significantly associated with reduced phenotypic variance in sexual orientation (β =  - 0.14, 95% CI - 0.27, - 0.01). A breakdown of the underlying influences of this moderation effect showed that this was mostly due to moderation of individual-specific environmental influences which significantly decreased as childhood gender nonconformity increased (βE =  - 0.38; 95% CI - 0.52, - 0.001) while additive genetic influences were not significantly moderated (βA = 0.05; 95% CI - 0.30, 0.27). We also observed that the relationship between sexual orientation and childhood gender nonconformity was stronger at higher levels of childhood gender nonconformity (β = 0.10, 95% CI 0.05, 0.14); however, significance of the underlying genetic and environmental influences on this relationship could not be established in this sample. The findings indicate that beyond a correlation of their genetic and individual-specific environmental influences, childhood gender nonconformity is further significantly associated with reduced individual-specific influences on sexual orientation.

The onset of mental health disparities in sexual minority and majority youth: evidence from the UK Millennium Cohort Study

Decades of research shows that sexual minority youth (SMY) display heightened risk for mental health problems, although the onset of such disparities remains unclear. The Millennium Cohort Study is the largest nationally representative longitudinal study of adolescents in the United Kingdom. In this study, participants (N = 10,047, 50% female) self-reported their sexual identity at age 17 and had parent-reported mental health data, from the Strengths and Difficulties Questionnaire, reported across five waves at ages 5, 7, 11, 14, and 17. Multilevel linear spline models, stratified by sex, were used to examine mental health trajectories between sexual identity groups (completely heterosexual, mostly heterosexual, SMY). SMY showed heightened peer problems from the baseline assessment at age five, increasing over time, and heightened emotional problems from age 11, increasing over time. Mostly heterosexual youth showed heightened emotional problems at age 11 in males, and at age 17 in females. Findings are discussed in light of the literature on minority stress and gender conformity in youth. The use of parent-reported mental health data means that estimates are likely to be conservative. We conclude that interventions supporting SMY should start early and be available throughout adolescence.

Contextualizing Cisgender Women's Histories of Intimate Partner Violence Victimization With Men and Women

Sexual minoritized women (SMW) are more likely than exclusively heterosexual women to experience intimate partner violence (IPV). We conducted in-depth interviews with a clinic-based sample of plurisexual SMW (n = 25) ages 18 to 34 about the gender of their perpetrators. Participants primarily experienced physical and sexual IPV in relationships with men and emotional abuse in relationships with women. IPV perpetrated by men often included weapons with women fearing for their lives. Offering patients information about IPV resources and supports that do not make assumptions about women's sexualities may create more opportunity for empathic and effective communication with SMW experiencing IPV.

What About the Sexual Orientation of the Offspring of Lesbian and Gay Parents? A Multidimensional, Time and Gender-Based Answer

This study examined the sexual orientation of 30 young adult children of lesbian and gay parents, analyzing three dimensions (sexual behavior, sexual attraction and sexual self-identification), their evolution over time and the possible influence of gender (19 women and 11 men). Sexual orientation was measured using KSOG. The results revealed that most participants defined themselves as heterosexual only, although percentages varied between 87% for sexual behavior to 67% for sexual attraction and 60% for sexual self-identification. Gender differences were found for sexual attraction and self-identification, with men having a polarized profile (responses at both ends of the scale) and women reporting a less exclusive and more fluid sexuality. These findings are discussed in light of the complex nature of sexual orientation, the freedom of these young adults for defining their sexual orientation, and the role played by gender and family experiences.

In support of 2D:4D: More data exploring its conflicting results on handedness, sexual orientation and sex differences

In the last few years, several studies have questioned the value of the second-to-fourth digit ratio (2D:4D) as a measure of exposure to sex hormones before birth. Controversy has also extended to the 2D:4D association with individual features previously related to this exposure such as handedness and sexual orientation. Given that it has been argued that sex differences in 2D:4D could be a consequence of body-size differences, we have tested in a large sample the allometric relationship between finger lengths and body size. Our results show that the association is either allometric or isometric, depending on the analyses performed. In any case, the deviation from isometry is not large enough to explain the typically observed sex difference in this trait. We have also tested the association between sexual orientation and 2D:4D, finding a relationship between 2D:4D and sexual orientation in men but not in women. We attribute this discordance with previously published meta-analysis to differences in genetic background, a variable that has gained relevance in recent years in studies involving 2D:4D. Finally, we did not find any relationship between 2D:4D and handedness, evaluated through self-reported preference and hand performance. Our main conclusion is that 2D:4D shows differences between sexes beyond their disparity in body size. In our opinion, 2D:4D can be used cautiously as an indicator of intrauterine exposure to sex hormones taking into account some considerations, such as analysing a very large sample and taking careful measurements of the ethnicity of the sample.

Is everyone a mix of straight and gay? A social pressure theory of sexual orientation, with supporting data from a large global sample

Sigmund Freud, Alfred Kinsey, E.O. Wilson, and others have suggested that social pressure suppresses natural tendencies for humans to express bisexuality, the apparent norm for one of our two closest genetic relatives, the bonobo. An analysis of data obtained from a new online sample of 1,150,938 people in 215 countries and territories (63.9% from the United States, United Kingdom, and Canada) who completed the English version of a validated questionnaire of sexual orientation lends support to this idea. A histogram of scores from 0 (exclusive opposite-sex inclinations) to 18 (exclusive same-sex inclinations) forms a near-normal distribution. Although this distribution was likely caused to some extent by sampling bias, it may also reflect the unusual honesty people show when taking online tests anonymously, as an increasing body of evidence demonstrates. We present a formal mathematical expression of a social pressure theory of sexual orientation, along with empirical evidence and computational explorations that support the theory. We also present an analysis of the new data set. Among other findings: sexual orientation labels corresponded to broad, skewed, overlapping distributions of scores. Self-labeled gays/lesbians and, to a greater extent, self-labeled straights, reported that the larger the mismatch between their sexual orientation label and their actual sexual inclinations, the more distress they felt regarding their sexual orientation, a finding that is predictable from cognitive dissonance theory. Educating the public about the true nature of sexual orientation might quell the often rancorous public debates on this topic, as well as give comfort to a large number of mislabeled people.

The Conditional Effects of Savoring on the Relationship between Minority Stress and Alcohol Misuse in an LGBTQIA + Sample

Background: Alcohol-related difficulties are a significant public health concern in lesbian, gay, bisexual, transgender, questioning, intersex, asexual, and people with other sexual orientations and forms of gender identity (LGBTQIA+) communities. Considering these concerns, there is a strong push to develop affirming and strength-based prevention efforts. Unfortunately, such efforts are undermined by the lack of protective LGBTQIA + models for alcohol misuse. To this end, the purpose of the current study was to evaluate whether savoring, the ability to create, maintain, and prolong positive emotions, meets basic criteria for a protective factor for alcohol misuse in a sample of LGBTQIA + adults. Methods: The sample was comprised of 226 LGBTQIA + adults who completed an online survey. Results: Results indicated that savoring was inversely related to alcohol misuse. In addition, the relationship between minority stress and alcohol misuse varied as a function of savoring; at high levels of savoring (a score of 136.63 on the Savoring Beliefs Inventory), the relationship between minority stress and alcohol misuse was non-significant. Conclusions: In combination, these findings offer preliminary support for savoring as a protective factor for alcohol misuse among different LGBTQIA + communities. However, longitudinal and experimental research is needed to solidify the role of savoring in minimizing alcohol-related problems in this population.

Sexual Victimization Among Sexual and Gender Minoritized Groups: Recent Research and Future Directions

PURPOSE OF THE REVIEW

Sexual victimization is a significant public health concern. Compared to heterosexual and cisgender peers, sexual and gender minoritized (SGM) individuals are at elevated risk for sexual victimization. Prominent theories suggest that this risk is due in part to the stigma SGM individuals face when navigating heteronormative cultures. The goal of this article is to review the prevalence, risk factors, and consequences of sexual victimization in SGM individuals.

RECENT FINDINGS

Studies continue to show that SGM individuals-bisexual and/or gender minoritized in particular-are at higher risk for sexual victimization. Little work has focused on risk factors, though recent research continues to highlight post-victimization disparities among SGM individuals. Emerging studies also point to theoretically informed factors that may influence victimization risk and recovery, including sexual and gender-related stigma. To inform prevention and intervention efforts, future research would benefit from streamlining assessment, methodology, and dissemination practices.

Do Beliefs About Sexual Orientation Predict Sexual Identity Labeling Among Sexual Minorities?

Research has found that sexual orientation beliefs predict heterosexuals' attitudes toward sexual minorities, and important sexual identity outcomes in sexual minority populations. To this point, no studies have systematically examined how sexual orientation beliefs may be associated with sexual identity self-labeling among sexual minority individuals. The present study examined this question in a sample of 1840 same-gender attracted individuals recruited for a cross-sectional online survey. Beliefs in the naturalness and discreteness of sexual orientation categories were highest in gay/lesbian individuals, intermediate in bisexual people, and lower in queer and pansexual individuals. Beliefs in the importance of sexual orientation were highest in gay/lesbian and queer identified individuals and lower in bisexual people. Within-group analysis demonstrated that gay/lesbian individuals who reported more exclusive same-gender attraction reported higher naturalness, discreteness, and importance beliefs than those with less-exclusive same-gender attraction. However, naturalness, discreteness, and importance beliefs were not associated with sexual attraction patterns in bisexual individuals. Finally, among predominately same-gender attracted populations, the adoption of a queer identity (over a gay/lesbian identity) was predicted by lower naturalness and discreteness beliefs, and increased perceived importance in females. Among non-monosexual populations, adoption of a pansexual identity over a bisexual identity was predicted by lower naturalness beliefs in females, but not predicted by sexual orientation beliefs in males. Collectively, these findings suggest that sexual orientation beliefs differ between sexual identity groups and may partly explain the adoption of particular sexual identity labels among contemporary sexual minority populations.

Fertility Intentions and Sexual Orientation: Evidence from the 2020 Youth Survey in Estonia

Attitudes towards sexual minorities have undergone a transformation in Western countries recently. This has led to an increase in research into the experiences of sexual minorities in a variety of life domains. Although parenthood is a valued life goal only a few small-scale studies have looked into the parenthood goals of individuals in relation to their sexual orientation. The aims of this study are to analyse the diversity of sexual orientation, the factors associated with it and the relationship to fertility intentions among adolescents aged 16 to 19. The study draws on a nationally representative youth survey conducted in 2020 in Estonia (N = 1624), and employs descriptive methods and logistic and linear regression models. The results show that adolescents in Estonia exhibit considerable diversity of sexual orientation, with one-fifth reporting some degree of attraction to their own sex. The minority sexual orientation is more frequent among groups which can be regarded as more open or exposed to new behaviours, but is also associated with a disadvantaged family background. The results reveal a clear negative association between the intended number of children and the minority sexual orientation, which is not explained by other available variables.

Stability and Change in Asexuality: Relationship Between Sexual/Romantic Attraction and Sexual Desire

This study examined the stability and change in asexuality in terms of sexual orientation identity, sexual/romantic attraction, and sexual desire. Data were collected in three waves at 12-month intervals (n = 168). In each wave, the participants completed measures of sexual/romantic orientation identity, sexual/romantic attraction, the Sexual Desire Inventory, and the Asexuality Identification Scale (AIS). Approximately 83% of asexual and gray-asexual individuals maintained their sexual orientation identity between two adjacent waves. The latent growth models indicated an increased tendency for sexual/romantic attraction and solitary sexual desire, while a decreased tendency for AIS over time was established. Only the sexual attraction slope significantly predicted asexual identity, indicating a longitudinal effect of sexual attraction on asexual identification. Initial levels of sexual attraction, and scores on the AIS and dyadic sexual desire (DSD) were associated with stability and changes in asexual identity. Asexual individuals who reported low sexual attraction, low DSD, and high AIS maintained their asexual identity, whereas those who reported high sexual attraction, high DSD, and low AIS were more likely to change their sexual orientation. The current findings indicate the relative stability of asexuality, which supports the notion that asexuality could be deemed a fourth sexual orientation.

Different Categorizations of Women's Sexual Orientation Reveal Unique Health Outcomes in a Nationally Representative U.S. Sample

BACKGROUND

Sexual minority women (i.e., women minoritized for their sexualities) are identified as high risk for mental health and substance use problems; however, there is no consensus on the criteria by which women are categorized as sexual minority. Though there is some evidence suggesting that certain subgroups of women are at higher risk than others based on sexual orientation, different categorization schemes for sexual orientation have yet to be compared within the same sample.

METHOD

Using data from the National Epidemiologic Survey of Alcohol and Related Conditions-III (N = 19,528), we examined how multiple categorization schemes (i.e., identity, behavior, recency of sexual behavior) for categorizing women who have sex with women (WSW) yield different estimates of prevalence of mental health and substance use issues. We used chi-square and logistic regression to analyze the link between sexual orientation categorization schemes and health, categorizing by 1) self-identification only, 2) behavior only, and 3) the combination of self-identification and behavior (recent vs. past).

RESULTS

We discovered high prevalence rates of health problems among heterosexual-identified WSW who reported no recent sexual activity with women (i.e., previously had sex with women but not within the past 12 months); this category of women comprised 35% of all WSW.

DISCUSSION

Step by step, we found more detailed information about these women's experiences by moving to the complex categorization scheme (the combination of self-identification and behavior). Heterosexual-identified women who have had sex with women in their past (though not recently) presented as a large group with high prevalence rates of substance use and mental disorders. These women remain invisible to researchers who categorize sexual orientation only by sexual identity or by behavior and ignore the role of behavior change over time-imprecisely categorizing such women as heterosexual or as women who have sex with men. They thus are underserved by health research and represent a significant population for further study and intervention.

A Qualitative Approach to Exploring the Impact of the Gay Identity Formation Process

Background

Most gay men experience difficulty in coming to terms with their sexual orientation, with their health, wellbeing, and quality of life potentially affected by unpleasant experiences often associated with the formation of their gay identity. It is therefore important for nurses to understand the needs of gay men so that they can accompany them and provide quality care during and after the identity formation process.

Objective

The aim of the study was to explore and describe the identity formation and coming out experiences of gay men.

Methods

A qualitative design with a constructivist naturalist approach was used. Data were collected through in-depth semi-structured interviews with five gay men with experience of the gay identity formation process, and data were analyzed using a thematic analysis method.

Results

The results show that the men needed support, as they reported feeling different and alone during the identity formation and coming out process, and that their mental health was affected. Fear of rejection, negative reactions, and disappointing people were the reasons that led the men not to disclose their sexual orientation to family, while those who had come out defined a feeling of liberation.

Conclusions

The gay identity formation process has potential impacts on health, wellbeing, and quality of life. Nurses need cultural competence training to be able to understand the needs of gay men, accompany them in the identity formation process, and provide individualized and non-heteronormative care. Nurses also need to participate in dismantling a heterosexist social structure.

Higher sexual excitation is associated with an increase in sex-linked substance use in women with a history of unwanted sexual contact

Survivors of unwanted sexual contact have an increased likelihood of using substances in sexual situations, which puts them at heightened risk for intoxication-related harms. Separately, research has indicated that women may intentionally use substances in sexual situations to either enhance pleasure (i.e., increase sexual excitation) and/or reduce sexual anxiety or shame (i.e., reduce sexual inhibition), a phenomenon termed sex-linked substance use (SLSU). A predominant assumption in the literature is that women with unwanted sex histories are more likely to disengage during sex, suggesting greater inhibition-related SLSU; however, there is little prior research directly examining if women who have unwanted sex histories primarily engage in SLSU to increase sexual excitation or decrease inhibitions. We conducted exploratory analyses of an online survey in a convenience sample of 516 undergraduate women including data on their history of unwanted sex, SLSU, and sexual excitation/inhibition. Sexual excitation mediated the association between a history of unwanted sexual contact and SLSU, suggesting that women with unwanted sexual histories reported higher levels of sexual excitation, which in turn was associated with a higher likelihood of using substances to increase pleasure during sexual activity. Specifically, arousability, partner characteristics, and power dynamics subfactors were significant mediators. Sexual inhibition did not mediate the relationship between a history of unwanted sexual contact and SLSU, suggesting that women with unwanted sex histories may have been less likely to use substances to reduce sexual inhibitions. If replicated, these findings suggest that sexual excitation may be a useful target of intervention surrounding SLSU, particularly in women with histories of unwanted sexual contact. Specifically, treatments targeting cognitive and affective tendencies associated with sexual excitation may help women who engage in SLSU to have safe, pleasurable sexual activity, without increasing the risk of intoxication-related harms.

Sexual Fluidity and Psychological Distress: What Happens When Young Women's Sexual Identities Change?

The sexual identities of young women today are less binary and more fluid than ever before. Several theoretical perspectives imply that this fluidity could be accompanied by distress. To examine this, we analyzed four waves of data from Australian women born 1989 to 1995 (n = 11,527). We found no evidence of a universal association between sexual identity change and psychological distress. Instead, psychological distress was elevated when women changed their identity away from the heterosexual norm and lowered when they changed their identity toward it. Social stress partly attenuated these associations. In addition, women unsure of their identity at multiple assessment points reported significantly greater psychological distress in the final assessment than women who were never unsure. Our findings suggest that greater support should be offered to women who are questioning their sexual identity or developing a minority identity.

Sexual and romantic spectrums: Mostly straights and mostly gays/lesbians

Sexual and romantic orientations and identities exist along a spectrum with varying degrees of compliance to traditional concepts of sex and romance. Recent investigations have focused on individuals who are not exclusive in their sexual and romantic lives-mostly straights and mostly gays/lesbians. Multi-disciplinary research reveals the diversity of individuals' internal and external sexual and romantic feelings and expressions. One corrective strategy is to scrap categorically based assessment tools and replace them with continuum measures that capture the multiplicity of individuals' sexual and romantic lives. Here I suggest several new measures that are more responsive to a spectrum approach.

A heavy burden: Associations between sexual minority status, mental health, and BMI in women

BACKGROUND

Sexual minority women (SMW) are at increased risk of elevated body mass index (BMI) compared to heterosexual women, increasing their vulnerability to chronic diseases. Nonmonosexual SMW appear to be at additional risk for elevated BMI, likely due to unique sexual minority stressors.

METHODS

A total of 437 SMW and heterosexual women completed a cross-sectional, online survey including self-report measures of sexual orientation dimensions, weight, psychological distress, and eating behaviors. We investigated relations among these variables to better understand disparities in self-reported BMI based on sexual orientation and sexual orientation discordance (SOD).

RESULTS

SMW self-reported more psychological distress, more binge eating, and higher BMIs than their heterosexual peers, with nonmonosexual groups of SMW often reporting the highest values. SOD was positively associated with psychological distress.

CONCLUSIONS

SMW-particularly nonmonosexual SMW-are at increased risk for psychological distress, binge eating, and elevated BMI relative to heterosexual peers. Future research should further elucidate mechanisms for these disparities.

Divergent patterns of cognitive deficits and structural brain alterations between older adults in mixed-sex and same-sex relationships

Background

Sexual minority (SM) older adults experience mental health disparities. Psychiatric disorders and neuropsychiatric symptoms (NPS) are risk factors for cognitive decline. Although older people in same-sex (SSR) compared to mixed-sex relationships (MSR) perform more poorly on cognitive screening tests, prior studies found no differences in rates of dementia diagnosis or neuropsychological profiles. We sought to explore the role of NPS on neurocognitive outcomes for SM populations. We compared cognitive performance and structural brain parameters of older adults in SSR and MSR.

Methods

Data were originally collected at Alzheimer's Disease Research Centers (ADRCs). Inclusion criteria were: age of 55+ years, a study partner identified as a spouse/partner, and availability of T1-MRI brain volumes/thickness. Participants were labeled as either SSR or MSR based on their/their co-participant's reported sex. We identified 1,073 participants (1,037 MSR-555 cognitively unimpaired [CU]; 36 SSR-23 CU) with structural MRI data, Mini-Mental State Exam (MMSE), and Neuropsychiatric Inventory Questionnaire (NPI-Q) scores. A subset of the overall sample completed comprehensive neuropsychological assessment (n = 939; 908 MSR-494 CU; 31 SSR-22 CU). Covariates included in statistical models were age, sex, education, total intracranial volume, and apolipoprotein E genotype.

Results

Multivariate general linear models showed significant diagnosis-by-relationship interaction effects on the left parahippocampal gyrus volume. After stratification by relationship group, only cognitively impaired (CI) MSR had significantly smaller left parahippocampal volumes than MSR-CU. The SSR group showed better episodic memory performance. Severity of neuropsychiatric symptoms was negatively associated with volume/thickness of bilateral fronto-temporal areas and with MMSE scores, predominantly in the MSR group.

Conclusion

In our study, MSR participants presented with a more compromised cognitive profile than SSR participants. MSR-CI participants showed significantly smaller left medio-temporal volumes, a neural signature of AD. Neuropsychiatric symptoms predicted smaller fronto-temporal volumes in the MSR more consistently than in the SSR group. These findings may be due to unexplored protective factors against cognitive decline in SM elders. Indeed, social support has been proposed as a protective factor warranting future investigation.

Effects of Friendship among Same-Sex Attracted Youth on Sexual Minority Identity Development in Young Adulthood

Using data from Waves 1 and 3 of the National Longitudinal Study of Adolescent to Adult Health, this study investigated the interactive impact of adolescent friendship network characteristics and same-sex attraction (SSA) on the development of sexual minority (SM) identity in young adulthood. Results indicate that SSA youth who identified a best friend that also identified them as their best friend were 5.3 times more likely to identify as a SM compared to those who did not experience reciprocity. For each additional classmate who listed them as a friend, SSA youth were 1.2 times more likely to identify as a SM. Increased centrality in friendship network increased the likelihood that SSA youth would identify as a SM by 1.8 times. Sex-stratified results reveal that particular network characteristics impact boys and girls differently. These findings point to the importance of further investigating relationships between friendship characteristics and identity formation among adolescents.

Heterosexual Identification and Same-Sex Partnering: Prevalence and Attitudinal Characteristics in the USA

This paper used the 2011-2017 National Survey of Family Growth to estimate population sizes and attitudinal characteristics of heterosexual-identified men who have sex with men (MSM) and women who have sex with women (WSW) aged 15-44 years. Analyses estimated population sizes in stages: after excluding respondents who reported only one lifetime same-sex partner, which happened before the age of 15; after excluding males who reported nonconsensual male-male sex; after excluding respondents who reported only one lifetime same-sex partner, regardless of the age at which that experience occurred; after excluding respondents who reported only two lifetime same-sex partners, the first of which occurred before age 15; and after excluding males who reported male-male sex work. The broadest criteria included many individuals with limited same-sex sexual histories or those who experienced nonconsensual sex or potentially coerced sex in youth. After excluding those respondents, analyses showed that heterosexual-identified MSM and WSW had a diversity of attitudes about gender and LGB rights; only a distinct minority were overtly homophobic and conservative. Researchers should carefully consider whether to include respondents who report unwanted sexual contact or sex at very young ages when they analyze sexual identity-behavior discordance or define sexual minority populations on the basis of behavior.

Sexual Identity-Behavior Discordance in Canada

This paper uses two surveys to examine sexual identity-behavior discordance in Canada. The first is the Sex in Canada survey (SCS), which is a private survey of 2,303 Canadians. The second is the 2015-2016 Canadian Community Health Survey (CCHS), which is a large nationally representative government-administered survey with 109,659 respondents. Results from the CCHS show that identity-behavior discordance and overall rates of same-sex contact are lower in Canada than in the US, UK, or Australia. An estimated .7 percent of males and 2.7 percent of females aged 15-64 who had had lifetime sex identified as heterosexual yet have had same-sex contact, figures which equate to an estimated 65,700 males and 255,100 females. Few demographic factors were associated with discordance. Results from the SCS show that about two-thirds of heterosexuals with identity-behavior discordance were moderately supportive of LGBQ rights and one-third were moderately homophobic. Future research will need to uncover why a lower proportion of Canadians report same-sex partners and identity-behavior discordance than their counterparts in the US, UK, or Australia. Cet article utilise deux enquêtes pour examiner la discordance entre l'identité sexuelle et le comportement au Canada. La première est l'enquête Sex in Canada (SCS), qui est une enquête privée menée auprès de 2 303 Canadiens. La seconde est l'Enquête sur la santé dans les collectivités canadiennes (ESCC) de 2015-2016, qui est une grande enquête représentative à l'échelle nationale administrée par le gouvernement auprès de 109 659 répondants. Les résultats de l'ESCC montrent que la discordance identité-comportement et les taux globaux de contacts entre personnes de même sexe sont plus faibles au Canada qu'aux États-Unis, au Royaume-Uni ou en Australie. On estime que 0,7 % des hommes et 2,7 % des femmes âgés de 15 à 64 ans ayant eu des rapports sexuels au cours de leur vie se sont identifiés comme hétérosexuels, mais ont eu des contacts avec des personnes du même sexe, ce qui correspond à environ 65 700 hommes et 255 100 femmes. Peu de facteurs démographiques étaient associés à la discordance. Les résultats de l'enquête SCS montrent qu'environ deux tiers des hétérosexuels présentant une discordance entre identité et comportement étaient modérément favorables aux droits des LGBQ et qu'un tiers était modérément homophobe. Les recherches futures devront découvrir pourquoi une plus faible proportion de Canadiens déclarent avoir des partenaires de même sexe et être en désaccord avec leur identité et leur comportement que leurs homologues aux États-Unis, au Royaume-Uni ou en Australie.

Exploring different profiles of gender (non)conformity in women and their relationship with sexual orientation and mental health

We examined whether sexual orientation and the Conformity to Feminine Norms (CFN) were predictors of three mental health outcomes: depression, anxiety, and self-esteem. The sample comprised 690 women with different sexual orientations (heterosexual, lesbian and bisexual). Our results suggested that there were five CFN profiles related to sexual orientation, but only the former was a significant predictor of the three mental health outcomes and that women might experience different forms of CFN which in turn can differentially influence women's mental health.

Multidimensional and Intersectional Gender Identity and Sexual Attraction Patterns of Adolescents for Quantitative Research

To identify and compare gender identity and sexual attraction (GISA) patterns using a latent class analysis (LCA), questionnaire data from a cross-sectional study on social resilience in adolescence was conducted in 2020, using a sample of 785 Swiss seventh grade high school students. Following McCall’s complex intersectionality approach, we applied an intracategorical and intersectional approach to reshape, differentiate, and critique the existing binary, heteronormative GISA categorization. To empirically validate the detected classes according to content, we measured the participants’ psychological characteristics with measures of self-esteem, social competence, symptoms of anxiety and depression, dissociation, social desirability, and emotional styles, and related these measures to the respective GISA patterns the LCA detected. The results of our multistep LCA endorsed that heteronormatively binary gender identities are far too simplistic to fully illustrate adolescents’ differences and similarities where gender is concerned. Out of the subsample of n = 785 adolescents (375 identified as “assigned females” and 410 “assigned males”), three significant subgroups of multidimensional GISA patterns emerged for both assigned females and males where differences within the identified GISA groups were larger than those between traditional “boys” and “girls” overall. The LCA demonstrated that the six classes with GISA indicators could be described as low GISA diverse (cis/heterosexual), intermediate GISA diverse (gender identity diverse and/or sexual diverse), high GISA diverse (gender diverse/sexual diverse) for both assigned males and females thus showing that GISA and the psychological state according to gender variance is greater within groups of assigned females and assigned males than between these groups.

Sexual Victimization and Disordered Eating in Bisexual Women: A Test of Objectification Theory

The current study (a) ascertained whether there is a relationship between sexual victimization (SV) and disordered eating (DE) among bisexual women, (b) assessed whether objectification theory explains the relationship, and (c) tested for group differences between bisexual and heterosexual women on SV, DE, and other objectification theory variables. Utilizing a sample of 164 undergraduate bisexual women, there was a significant positive relationship between SV and DE that was serially mediated by self-surveillance and body shame. In addition, bisexual participants endorsed more SV, DE, body shame, and interoceptive deficits than a comparison sample of 335 undergraduate heterosexual women. Implications are discussed.

The New Genetic Evidence on Same-Gender Sexuality: Implications for Sexual Fluidity and Multiple Forms of Sexual Diversity

In September of 2019, the largest-ever (N = 477,522) genome-wide-association study of same-gender sexuality was published in Science. The primary finding was that multiple genes are significantly associated with ever engaging in same-gender sexual behavior, accounting for between 8-25% of variance in this outcome. Yet an additional finding of this study, which received less attention, has more potential to transform our current understanding of same-gender sexuality: Specifically, the genes associated with ever engaging in same-gender sexual behavior differed from the genes associated with one's relative proportion of same-gender to other-gender behavior. I review recent research on sexual orientation and sexual fluidity to illustrate how these findings speak to longstanding questions regarding distinctions among subtypes of same-gender sexuality (such as mostly-heterosexuality, bisexuality, and exclusive same-gender experience). I conclude by outlining directions for future research on the multiple causes and correlates of same-gender expression.

Exposure to continuous or fluid theories of sexual orientation leads some heterosexuals to embrace less-exclusive heterosexual orientations

We examined whether heterosexual individuals' self-reported sexual orientation could be influenced experimentally by manipulating their knowledge of the nature of sexual orientation. In Study 1 (180 university students, 66% female) participants read summaries describing evidence for sexual orientation existing on a continuum versus discrete categories or a control manipulation, and in Study 2 (460 participants in a nationally representative Qualtrics panel, 50% female) additionally read summaries describing sexual orientation as fluid versus stable across the life-course. After reading summaries, participants answered various questions about their sexual orientation. In Study 1, political moderates and progressives (but not conservatives) who read the continuous manipulation subsequently reported being less exclusively heterosexual, and regardless of political alignment, participants reported less certainty about their sexual orientation, relative to controls. In Study 2, after exposure to fluid or continuous manipulations heterosexual participants were up to five times more likely than controls to rate themselves as non-exclusively heterosexual. Additionally, those in the continuous condition reported less certainty about their sexual orientation and were more willing to engage in future same-sex sexual experiences, than those in the control condition. These results suggest that non-traditional theories of sexual orientation can lead heterosexuals to embrace less exclusive heterosexual orientations.

Age, sex, and other demographic trends in sexual behavior in the United States: Initial findings of the sexual behaviors, internet use, and psychological adjustment survey

It remains unclear how the seemingly ubiquitous use of the internet impacts user's offline personal relationships, particularly those that are romantic or sexual. Therefore, we conducted a national online survey to better understand the associations among internet use, sexual behavior, and adjustment called the Sexual Behaviors, Internet Use, and Psychological Adjustment Survey (SIPS). Here, we report patterns of sexual behavior in a sample of adults (N = 1987; ages 18-70) in the United States to establish its representativeness and consistency with similar recent surveys. We found age- and sex-related trends in oral, vaginal, and anal sex in terms of prevalence, frequency, number of partners, and age of initiation consistent with prior studies. We also detected differences in sexual behaviors based on relationship status and sexual orientation, but small and relatively few significant differences across racial and ethnic groups. The results confirm and expand upon trends identified in prior national surveys of sexual behavior, establishing the representativeness of the SIPS sample for use in future research examining the links among sexual behaviors and romantic relationships, internet use, and adjustment.

Sexual excitation and sex-linked substance use predict overall cannabis use in mostly heterosexual and bisexual women

Background: Bisexual and mostly heterosexual women report higher substance use than exclusively heterosexual or lesbian women. In sexual minority men, sex-linked substance use (SLSU) can increase risk for substance use problems; equivalent research in women is lacking.Objectives: To test if sexual excitation and inhibition mediate the association between sexual minority status and women's SLSU.Methods: We surveyed a convenience sample of 595 undergraduate women who identified as exclusively heterosexual (n = 499), mostly heterosexual (n = 59), or bisexual (n = 37). Participants reported on their last month use of alcohol, cannabis, and other drugs (e.g., cocaine) in sexual and non-sexual contexts, and symptoms of alcohol and non-alcohol drug use disorders (e.g., withdrawal symptoms). Drug use symptoms were collapsed across non-alcohol substances. We used structural equation modeling to test serial mediations of women's SLSU and overall drug and alcohol use.Results: Bisexual and mostly heterosexual women reported higher cannabis use (η2 = 0.030) and drug use disorder symptoms (η2 = 0.050) than heterosexual women. Mostly heterosexual women's SLSU was a stronger predictor of alcohol use (η2 = 0.019) and binge drinking frequency (η2 = 0.015) than for other orientation groups. Bisexual and mostly heterosexual women's higher sexual excitation predicted their higher SLSU, which in turn predicted higher cannabis use frequency and drug use disorder symptoms. However, sexual inhibition failed to mediate either SLSU or overall substance use.Conclusion: These findings point to SLSU as a mechanism by which sexual minority women may experience disparities in substance use related harms.

Relying on an "Other" Category Leads to Significant Misclassification of Sexual Minority Participants

Purpose: This study assessed which sexual minority participants selected "Other" if their identity was absent. Methods: This was an online survey; 905 participants saw a limited set of sexual orientation options (bisexual, gay/lesbian, heterosexual, other), and later in the same survey, saw an expanded list. Results: Twenty-one percent of participants chose different orientation labels across questions. When not presented with a "mostly heterosexual" option, 78% of mostly heterosexual participants chose "heterosexual"; 3% chose "other." However, when not presented with an "asexual" label, 100% of asexual participants chose "other." Conclusion: These findings suggest that "other" categories could misclassify a substantial proportion of sexual minority participants.

Changes in Sexual Identity Labels in a Contemporary Cohort of Emerging Adult Women: Patterns, Prevalence and a Typology

Sexual attraction, behavior and identity are subject to change across the life course for some individuals, and certain developmental periods such as emerging adulthood appear particularly conducive to this. However, the evidence documenting these phenomena comes overwhelmingly from data collected 10-20 years ago. In the brief interlude since, the socio-political context has changed markedly and increasing numbers of women are reporting non-heterosexuality. Drawing on contemporary data from the Australian Longitudinal Study on Women's Health (n = 16,870), we provide up to date evidence on changes in sexual identity labels among emerging adult women. We found that 19% of women changed their sexual identity label from one survey wave to the next, and 30.6% changed their identity label at least once across the four waves. Mostly heterosexual and bisexual labels were both more common and more stable in our sample than in previous studies. We propose a new typology of sexual identity sequences and fit this to our data, providing a blueprint for researchers looking to define sexual minority status longitudinally. Findings suggest that the ways women perceive and label their sexual orientation should be treated as dynamic phenomena situated within the nested temporalities of biographical and historical time.

Stories Told Together: Male Narratives of Non-Monogamous Bi+ and Heterosexual Men

The stories we tell about our identities and sexual orientations shape how we perform gendered scripts and negotiate relationships with significant others. Previous literature inquired the styles and outcomes of consensual non-monogamous (CNM) relationships, but more research is need on how CNM men resist or abide to hegemonic models of masculinity. To understand how constructions of masculinity and conceptualizations of sexual orientation are embedded in CNMs, the study analysed the stories of non-monogamous Bi+ and heterosexual men. Following a critical narrative approach, the study inquired the diverse conceptualizations of masculinity, sexual orientation and relationship practices in the narratives of 20 non-monogamous Bi+ and heterosexual identified men. The semi-structured in-depth narrative interviews (105 min on average) were analyzed via Nvivo 12 and explored their stories of desire and the sense-making process of being sexually oriented to one or more genders and to one or more partner/s. Engaging in non-monogamy was signified as a relevant insight from their personal stories and/or from adopting new concepts of desire beyond the "love as a zero-sum game." The latter theme was also shared by many heterosexual participants that, when negotiating a non-monogamous agreement, signified their attractions to more than one person as part of their personal identity. Finally, the paper discusses how non-monogamous spaces can offer a positive and safe space for bisexuals/Bi+ people to explore and reaffirm their identities, constantly challenged by biphobia, invisibility, and erasure. Experiences and stories of Italian cisgender Bi+ and heterosexual men cannot be generalized to the whole spectrum of masculinities within CNM spaces, and the study lacks how other gendered and sexual subjectivities construct masculinity. Diverse stories and construction of sexuality and gender can lead to similar relationship preferences and understanding how we signify them can greatly improve our understanding of intimacies.

Gender Similarities and Differences in Casual Sex Acceptance Among Lesbian Women and Gay Men

Popular wisdom and scientific evidence suggest women desire and engage in casual sex less frequently than men; however, theories of gender differences in sexuality are often formulated in light of heterosexual relations. Less is understood about sexual behavior among lesbian and gay people, or individuals in which there is arguably less motivation to pursue sex for reproductive purposes and fewer expectations for people to behave in gender-typical ways. Drawing from scripts theory and pleasure theory, in two studies (N₁ =  465; N₂ =  487) we examined lesbian and gay people's acceptance of casual sex. We asked participants who had been propositioned for casual sex whether they accepted the offer and to rate their perceptions of the proposer's sexual capabilities and sexual orientation. They also reported on their awareness of stigma surrounding casual sex. We found a gender difference in acceptance: Gay men were more likely than lesbian women to have accepted a casual sex offer from other gay/lesbian people, and this difference was mediated by participants' stigma awareness. We also found the proposer's sexual orientation played a role in people's acceptance. Lesbian women and gay men were equally likely to accept offers from bisexual proposers but expressed different acceptance rates with "straight-but-curious" proposers, which was mediated by expected pleasure. We discuss dynamics within lesbian and gay communities and implications for studying theories of sexual behavior and gender differences beyond heterosexual contexts.

An examination of emotion regulation as a mechanism underlying eating disorder pathology in lesbian, gay, and bisexual individuals

OBJECTIVE

Lesbian, Gay, and Bisexual (LGB) individuals generally experience eating disorders at higher rates than heterosexual individuals. While there is limited research examining why LGB individuals experience higher levels of eating pathology, emotion regulation (ER) deficits have been associated with higher rates of other forms of psychopathology in this population. The present study examined the impact of specific ER deficits on the relationship between LGB status and eating pathology. We hypothesized that 1) LGB individuals would report higher levels of ER deficits, and 2) ER deficits would mediate the relationship between LGB status and eating pathology.

METHOD

Participants were 195 LGB and 193 heterosexual adults recruited via mTurk who completed self-report measures of eating pathology and ER deficits.

RESULTS

One-way ANCOVA analyses revealed that LGB individuals reported higher levels of ER deficits compared to heterosexuals for all DERS subscales except for DERS-Awareness. Nearly all DERS subscales (DERS-Nonacceptance, DERS-Goals, DERS-Strategies, DERS-Impulse) significantly mediated the relationship between LGB status and eating pathology.

DISCUSSION

Consistent with our hypotheses, LGB individuals reported higher levels of ER deficits compared to heterosexuals and specific ER deficits partially accounted for the relationship between LGB status and eating pathology. Future research should utilize longitudinal designs to examine whether the ER deficits identified in the present study prospectively predict eating pathology. Considering the immense mental health burden placed on the LGB community, it is essential that research continue to identify the unique needs of LGB individuals to more effectively treat and prevent psychopathology, including eating disorders, in this population.

Family Belongingness Attenuates Entrapment and Buffers Its Association with Suicidal Ideation in a Sample of Dutch Sexual Minority Emerging Adults

Sexual minority emerging adults are more likely to engage in suicidal ideation than their heterosexual counterparts. Experiences of homophobic violence are associated with suicidal ideation. Yet, the specific mechanisms linking homophobic violence to suicidal ideation remain unclear. Entrapment and social belongingness were tested to determine their relevance for understanding the link between homophobic violence and suicidal ideation. A sample of sexual minority Dutch emerging adults (N = 675; ages 18-29, M = 21.93 years, SD = 3.20) were recruited through online platforms and flyers. Homophobic violence was expected to be positively associated with suicidal ideation and entrapment. The association between homophobic violence and suicidal ideation was expected to be indirectly linked through entrapment. We explored whether various sources of social belongingness moderated the path between entrapment and suicidal ideation and whether those sources of social belongingness moderated the indirect effect of homophobic violence on suicidal ideation through entrapment. Results showed that homophobic violence and entrapment were positively associated with suicidal ideation and that family belongingness was negatively associated with suicidal ideation. Homophobic violence and suicidal ideation were not indirectly linked through entrapment. The interaction effect between entrapment and family belongingness was significant, suggesting that, on average, the effect of entrapment on suicidal ideation decreased when family belongingness was high. These results suggest that family belongingness may reduce the association between entrapment and suicidal ideation while adjusting for homophonic violence. Reducing entrapment and improving family belongingness may be useful targets for programs aimed at preventing suicidal ideation among sexual minority emerging adults.

"Why Should I, the One Who Was Raped, Be Forced to Take Training in What Sexual Assault Is?" Sexual Assault Survivors' and Those Who Know Survivors' Responses to a Campus Sexual Assault Education Program

This study critically examines sexual assault survivors' (people with histories of sexual assault) and those who know survivors' (those who know and/or who are close to people with histories of sexual assault) responses to a mandatory online campus sexual assault education program using both quantitative survey data (N = 1,899) and qualitative narratives (n = 41) from a sample of students at a large southern university with special attention to gender, sexual identity, race, ethnicity, college group affiliations (student athletics, fraternities/sororities, LGBTQ [lesbian, gay, bisexual, and transgender, queer] ally programs), and the intersections between these identities and affiliations. The quantitative findings show that knowing/being a woman survivor is positively related to supportive attitudes toward the sexual assault education program and inversely, knowing/being a man survivor is negatively related to support of the program. In addition, being a woman, being gay/lesbian, being Black/African American, Asian/Pacific Islander, Native American/Alaskan Native, or another race, and being a sorority member are all significantly related to supportive attitudes toward the sexual assault education program. Furthermore, qualitative analyses revealed that the majority of personal survivors' narratives indicated traumatic/triggering responses whereas most of those who provided narratives about knowing survivors(s) indicated praiseworthy reactions. Overall, the current study offers empirically driven sexual assault education program implications that acknowledge survivors' and those who know survivors' experiences with the ultimate goal of determining how to best meet students' needs.

Suicide thought and behaviors, non-suicidal self-injury, and perceived life stress among sexual minority Mexican college students

BACKGROUND

Sexual minority college students are at a higher risk for suicidal thoughts and self-injurious behaviors compared to heterosexual students. Minority stress theory proposes sexual minority individuals experience higher stress due to stigma. Using a sample of Mexican college students, this study tested perceived life stress as a mediator of suicide and self-injury outcomes across various sexual orientation groups.

METHODS

The sample of college students (N=7882) was recruited from nine Mexican universities as part of the WHO World Mental Health International College Student (WMH-ICS) initiative. Participants completed an online survey including demographic questions, measure of perceived life stress, suicide outcomes, and non-suicidal self-injury (NSSI) in the past 12 months.

RESULTS

Logistic regression analyses revealed identifying as a sexual minority significantly predicted a higher likelihood of suicide ideation (ORs 2.05-3.00), suicide attempts (ORs 2.48-8.73), and NSSI (ORs 2.92-4.18) compared to heterosexual students reporting no same-gender attraction. Significant indirect effects from mediation path analyses showed perceived life stress mediated the relationship between a sexual minority identity and suicide ideation (range of proportion mediated 10.48-31.48%), attempts (10.48-31.48%), and NSSI (7.69-20.09%) across each group except among asexual students.

LIMITATIONS

The cross-sectional nature of the survey design precludes drawing causal inferences.

CONCLUSION

Findings from this study contribute to minority stress theory by elucidating the role of perceived life stress as a mediator of suicide ideation and attempts and NSSI among sexual minority college students. Clinical interventions may benefit in focusing on experiences of stress across various life areas when supporting sexual minority college students.

Patterns of Bullying Behavior by Sexual Orientation

Bullying has a long-lasting effect on both victims and their perpetrators; however, there is little literature dedicated to understanding the roles of sexual minority adolescents beyond being a victim or the specific types of bullying behaviors (verbal, relational, physical) in which sexual minority adolescents engage. Even less is known about the experiences of mostly heterosexual youth, as distinct from their lesbian, gay, and bisexual (LGB) peers. This exploratory study sought to identify sexual orientation differences in bullying behavior participation using a random cluster sample obtained from a county school district in the Southeastern United States. The sample included 3,463 middle and high school students from 66 schools. Four latent classes of bullies and victims emerged, with similar patterns of behaviors for heterosexual, mostly heterosexual, and LGB groups.

Risk and protective factors for suicide among sexual minority youth seeking emergency medical services

BACKGROUND

Differences in risk and protective factors (e.g., victimization, abuse, social support) have been used to explain elevated rates of suicidal ideation and suicide attempts in sexual minority youth (SMY) relative to heterosexual peers. However, little is known regarding how risk and protective factors may explain suicide risk differences among subgroups of SMY. The aims of this study were to 1) examine differences in prevalence and severity for suicide risk and protective factors among SMY, and 2) explore whether risk and protective factors are differentially associated with suicidal ideation and suicide attempts for SMY subgroups.

METHODS

Participants were 6,423 adolescents (ages 12-17) recruited from 14 Emergency Departments across the United States who completed an assessment of suicide risk and protective factors. SMY were 20% of the sample (n = 1,275) and categorized as bisexual (8%), gay/lesbian (2%), mostly straight (5%), or other sexual minority (5%).

RESULTS

Bisexual youth had elevated rates of suicidal ideation and attempts, more risk factors (e.g., bullying victimization, depression), and fewer protective factors (e.g., parent-family connectedness, positive affect) relative to mostly straight and other sexual minority youth. Bisexual and gay/lesbian youth only differed in parent-family connectedness (lower among bisexual youth). Depression and parent-family connectedness had weaker associations with suicidal ideation for bisexual youth.

LIMITATIONS

Emergency departments were not nationally representative. Study design was cross-sectional, preventing causal inferences.

CONCLUSIONS

Interventions seeking to mitigate risk factors and promote protective factors are greatly needed for SMY and may benefit from tailoring to address unique stressors for sexual minority subgroups.
