The Role of Shame in Associations with PTSD and Depression Symptoms and Hazardous Drinking Among Bisexual Women Who Experienced Sexual Violence.

Bisexual (i.e. those with attraction to multiple genders) women experience disparities in sexual violence and mental health outcomes, including PTSD, depression, and hazardous drinking, compared to lesbian and heterosexual women. Unique stigma due to bisexual identity (antibisexual stigma), negative reactions to sexual violence (SV) disclosure (e.g. victim blaming), and prior child sexual abuse (CSA) may all contribute to shame. We tested whether shame explained the associations of antibisexual stigma, negative reactions to SV disclosure, and CSA severity with PTSD symptoms, depression, and hazardous drinking among young bisexual women. Participants who self-identified as bisexual women, between the ages of 18-35, residing in the US were recruited via Amazon's Mechanical Turk (MTurk) and completed online questionnaires. Women who reported SV since age 18 that they disclosed to someone were included in the current study, yielding a sample of 156 bisexual women (Mage = 25.7; 98.1% cisgender, 86.5% White). Path analysis with bias-corrected bootstrapping was conducted. There were significant direct effects of negative reactions on hazardous drinking and CSA on PTSD, and direct effects of shame on PTSD and depression symptoms. Shame explained the associations of antibisexual stigma, negative reactions, and CSA with PTSD symptoms, depression symptoms, and hazardous drinking. Shame may explain why stigmatizing experiences related to bisexual identity, sexual violence, and CSA history relate to distress among bisexual women. Shame is an important treatment target among bisexual survivors of SV.
