Navigating Heterosexism: Unveiling the Impact of Isolation on Posttraumatic Stress Disorder Severity in Sexual Minority Women

This is the authors' abstract. We don't add key points for this paper.

Sexual minority women (SMW) face elevated trauma and PTSD rates compared to heterosexual peers. This study tested whether specific dimensions of heterosexism contribute to PTSD severity among 514 trauma-exposed SMW (ages 18–25). Self-reported heterosexism was positively associated with PTSD symptoms (β = .33, p < .115). Findings highlight the central role of isolation in PTSD among SMW, underscoring the importance of targeted, affirming mental health care.
