Social Support as a Mediator of Anti-Bisexual Prejudice and Posttraumatic Stress Disorder Symptoms.

Among sexual minorities, bisexual individuals experience higher rates of victimization and symptoms of PTSD than their lesbian and gay peers as well as heterosexual individuals. Despite these disparities, little work has examined factors contributing to PTSD symptoms among bisexual adults. The current study examined the associations between bisexual-specific minority stress and PTSD symptoms in a sample of adults with bisexual orientation and tested social support as a potential mediator of this association. Participants were 488 adults (378 cisgender women, 49 cisgender men, 61 transgender individuals), ages 18 to 66 years, with bisexual orientation based on identity and/or attraction to multiple genders. Greater anti-bisexual prejudice was associated with greater PTSD symptoms (ß = 0.16) and lower social support (ß = -.16), while accounting for sociodemographics and sexual identity-based victimization. Social support was associated with lower PTSD symptoms (ß = -.25), while accounting for sociodemographics, sexual identity-based victimization, and anti-bisexual prejudice. Mediation analyses indicated that anti-bisexual prejudice was indirectly associated with greater PTSD symptoms through lower social support. Addressing bisexual-specific minority stress and its role in diminishing social support for bisexual individuals represents a critical component of trauma-informed research and intervention development in the bisexual community.

Perceived Discrimination, Coping Mechanisms, and Effects on Health in Bisexual and Other Non-Monosexual Adults.

Bisexual individuals experience unique discrimination related to their sexual orientation, which may increase their risk of adverse health outcomes. The study goal was to investigate how bisexual and other non-monosexual individuals experience discrimination, understand how they perceive discrimination to affect their health, and examine the ways in which they cope with discrimination by analyzing responses to open-ended survey questions. The sample included 442 bisexual and other non-monosexual adults, ages 18-68 years (M = 28.97, SD = 10.30), who either reported a bisexual identity or reported attractions to more than one gender. Gender identities included women (n = 347), men (n = 42), and transgender/non-binary individuals (n = 53); 29% of participants were currently located outside of the U.S. Participants completed an online survey, including three open-ended questions regarding their experiences with discrimination, how discrimination affects their health, and methods used to cope with discrimination. Themes related to perceived discrimination included: double discrimination of bisexuals and other non-monosexual individuals by heterosexuals, lesbian and gay individuals; bisexual invalidation and erasure; and sexual victimization. Themes related to the perceived effects of discrimination on health included: impact on mental health; impact on physical health; and effect of discrimination in healthcare. Themes related to coping with discrimination included: social support; resilience; and identity-specific media consumption. Findings demonstrate that bisexual and other non-monosexual individuals' experiences of discrimination can be additive, based on other marginalized facets of identity, including race/ethnicity, gender, and socioeconomic status. Our findings have implications for advancing bisexual health research from an intersectionality framework.

Psychometric validation of the identity abuse scale among LGBTQ individuals.

Identity abuse (IA) comprises a set of abuse tactics that exploit discriminatory systems including homophobia, biphobia, and transphobia (Tesch & Berkerian, 2015). This study examined the factorial validity of the IA Scale (Woulfe & Goodman, 2018) with a large independent sample of lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals. Participants included 1,049 LGBTQ-identified participants (Mage  = 27.3, 71.9% White, 52.6% cisgender women, and 18.7% as other nonheterosexual identity in their sexual orientation), recruited through listservs. Participants completed an online survey measuring past-year and adult exposure to identity, physical, and psychological abuse. Confirmatory factor analysis indicated that the measurement model had good fit to the data, and strong factor loadings were found across the seven items, confirming a unidimensional factor structure. Findings demonstrate the IA Scale's validity and reliability, supporting its use to assess the frequency of IA tactics experienced within intimate partnerships among LGBTQ individuals.

Identity Abuse as a Tactic of Violence in LGBTQ Communities: Initial Validation of the Identity Abuse Measure.

Intimate partner violence (IPV; i.e., physical, sexual, or psychological abuse by a current or former partner) remains a public health concern with devastating personal and societal costs. Lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals are also vulnerable to a dimension of IPV called identity abuse (IA); that is, abuse tactics that leverage systemic oppression to harm an individual. Yet, we know little about its relative prevalence in subgroups of the LGBTQ community. This study developed and evaluated a measure of IA, and explored its prevalence in a sample of 734 sexual minority adults. The sample included women (53.1%), men (27.4%), and transgender or gender nonconforming "TGNC" (19.3%) participants. The majority of participants identified as queer or pansexual (38.7%), then gay (23.6%), lesbian (22.8%), and bisexual (13.6%). Participants completed an online survey that included measures of IA and physical, sexual, and psychological abuse. The IA items formed a unidimensional factor structure with strong internal consistency and construct validity. Nearly one fifth of the sample (16.8%) experienced past year IA and 40.1% reported adult IA. Women experienced greater exposure to IA in adulthood than men, and TGNC participants reported higher rates of IA in adulthood and in the last year compared to their cisgender counterparts. The odds of queer or bisexual participants reporting IA in adulthood were almost three times higher than gay participants, and two times higher than lesbian participants. Findings have implications for advancing assessment of partner abuse in the LGBTQ community, LGBTQ-competent clinical care, and training of practitioners.

Associations between anti-bisexual minority stress and body esteem and emotional eating among bi+ individuals: The protective role of individual- and community-level factors.

Bisexual individuals experience prejudice specifically related to their bisexual identity, and these experiences may compound extant risk for disordered eating behaviors and body esteem concerns. However, little is known about how sexual minority stress related to bisexual orientation is associated with emotional eating and body esteem. The current study examined the associations between bisexual-specific minority stress and emotional eating and body esteem in a sample of bisexual plus (bi+) adults (including bisexual, pansexual, queer, and those with attractions to more than one gender regardless of identity), and tested the moderating effects of identity centrality, affirmation, and community connectedness as potential protective factors. This study leveraged data from an online survey of 498 adults (77.46% cisgender women; 79.7% White), ages 18 to 64 years (M = 28.5; SD = 9.59). Bisexual-specific minority stress was associated with more emotional eating (ß = 0.15, p = .013) and lower body esteem (ß = -0.16, p = .005), while controlling for sociodemographic characteristics, body mass index, and heterosexist minority stress. This finding remained the same when sensitivity analyses were conducted with participants who identified specifically as bisexual. Identity centrality and affirmation and community connectedness did not demonstrate moderating effects but they had main effects, such that they were positively associated with body esteem (ß = 0.16, p = .001; ß = 0.21, p < .001; ß = 0.13, p = .004, respectively). Results suggest that anti-bisexual minority stress has a unique association with bi+ individuals' emotional eating and body esteem, and identified potential individual- and community-level protective factors for body esteem. These findings inform future research and interventions for this understudied population.

Self-Reported Mental and Physical Health Symptoms and Potentially Traumatic Events Among Lesbian, Gay, Bisexual, Transgender, and Queer Individuals: The Role of Shame.

OBJECTIVE: Lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals disproportionately face exposure to potentially traumatic events-adverse experiences that may have a traumatizing effect-and experience shame as a common consequence. Previous research demonstrates associations between shame and psychological and physical health issues among those with exposure to potentially traumatic events in general, with limited attention among LGBTQ individuals specifically. This study determined whether shame partially mediated the relationship between potentially traumatic events exposure and self-reported mental and physical health symptoms among LGBTQ individuals. METHOD: Participants were 218 self-identified LGBTQ individuals who reported experiencing at least one potentially traumatic event (e.g., childhood sexual abuse). Online surveys assessed the type and frequency of potentially traumatic events exposure, shame, self-reported mental health (depression symptoms, posttraumatic stress disorder symptoms, and substance use), and physical health symptoms (sexual risk behavior, somatic symptoms, and chronic health conditions). RESULTS: Greater potentially traumatic events exposure was associated with greater shame, and greater shame was associated with worse self-reported mental and physical health. Potentially traumatic events exposure had a direct effect on self-reported mental and physical health, and shame partially mediated this relationship. CONCLUSION: Shame represents an important and modifiable factor that relates to poor health and may be amenable to change through psychosocial interventions. Given the prevalence of negative self-attribution stemming from potentially traumatic events exposure, in addition to the internalization of stigma among this population, practitioners need to uncover interventions specifically targeting shame when working with LGBTQ individuals.
