Bisexual+ (e.g., bisexual, pansexual, queer) women experience higher rates of sexual violence (SV) and posttraumatic stress disorder (PTSD) than heterosexual and lesbian women, as well as unique identity-related minority stress. We examined between- and within-person associations between bisexual minority stress and PTSD symptoms related to SV in a sample of young bisexual+ women (N = 133) who reported adult SV (M = 22.0 years, range: 18-25 years; 85.0% White; 99.3% cisgender). We analyzed data from four waves of data collection (baseline to 3-month follow-up) using multilevel models. Controlling for SV severity, there was a significant within-person effect of antibisexual stigma from lesbian/gay people on PTSD, β = .17, p = .010, suggesting that at waves when women experienced more stigma, they also reported higher PTSD symptom levels. At the between-person level, women who reported higher levels of antibisexual stigma from heterosexual people, β = .26, p = .043, and anticipated binegativity, β = .29, p = .005, on average across study waves also reported higher average levels of PTSD. Additionally, anticipated binegativity explained the association between average antibisexual stigma and PTSD, β = .15, p = .014, 95% CI [0.45, 4.61]. Bisexual minority stress may be associated with higher PTSD symptom severity following SV among young bisexual+ women, and the anticipation of binegativity may be a target mechanism in this association. Study findings highlight the importance of examining the joint contributions of SV and minority stress to identify novel targets for future research and practice to address PTSD symptoms.
双性恋+（如双性恋、泛性恋、酷儿）女性遭受性暴力（SV）和创伤后应激障碍（PTSD）的比率高于异性恋和女同性恋女性，她们还面临与身份认同相关的独特的少数群体压力。我们在一个报告有成人期性暴力经历的年轻双性恋+女性样本（N = 133）中，研究了双性恋少数群体压力与与性暴力相关的创伤后应激障碍症状之间的组间和个体内关联（平均年龄M = 22.0岁，范围：18 - 25岁；85.0%为白人；99.3%为顺性别者）。我们使用多层次模型分析了四轮数据收集（从基线到3个月随访）的数据。在控制性暴力严重程度后，来自女同性恋/男同性恋者的双性恋歧视对创伤后应激障碍有显著的个体内效应，β = .17，p = .010，这表明在女性经历更多歧视的阶段，她们报告的创伤后应激障碍症状水平也更高。在组间水平上，在各研究阶段平均报告来自异性恋者的双性恋歧视水平较高（β = .26，p = .043）以及预期的双性恋消极态度较高（β = .29，p = .005）的女性，其创伤后应激障碍的平均水平也较高。此外，预期的双性恋消极态度解释了平均双性恋歧视与创伤后应激障碍之间的关联，β = .15，p = .014，95%置信区间[0.45, 4.61]。双性恋少数群体压力可能与年轻双性恋+女性遭受性暴力后更高的创伤后应激障碍症状严重程度相关，而对双性恋消极态度的预期可能是这种关联中的一个目标机制。研究结果凸显了考察性暴力和少数群体压力的共同作用对于确定未来研究和实践中解决创伤后应激障碍症状的新目标的重要性。
