Comparing LGBTQIA+ and Non-LGBTQIA+ Knowledge of Queer History: Implications for Historical Trauma

Historical trauma is a legacy of loss, grief, and violence that reverberates throughout generations. Research shows that historical trauma contributes to health disparities among racial and ethnic minorities. However, its impact on LGBTQIA+ individuals remains unstudied, as trauma may not be passed intergenerationally within families. Investigating how LGBTQIA+ individuals are affected by historical trauma would help improve mental health treatment and reduce health disparities. We aimed to develop a measure of historical trauma related to LGBTQIA+ history. To do so, we also assessed undergraduate students’ knowledge of LGBTQIA+ history across two universities. In the current study, n = 455 students participated. Of these, n = 136 (29.8%) identified as LGBTQIA+ or part of the queer/transgender spectrum. Among non-LGBTQIA+ students (n = 319), n = 199 identified as allies to the LGBTQIA+ community. Participants completed 13 multiple-choice questions assessing their knowledge of LGBTQIA+ history. An independent samples t-test was conducted to compare knowledge of LGBTQIA+ history between LGBTQIA+ individuals and non-LGBTQIA+ individuals. Results showed a significant difference in knowledge of LGBTQIA+ history, t (444) = 7.889, p < .001, d = .817. LGBTQIA+ individuals (M = 4.384, SD = 3.268) were more knowledgeable than non-LGBTQIA+ individuals (M = 1.987, SD = 2.782). These results demonstrate that LGBTQIA+ individuals are far more familiar with their community’s history. These findings are the start of understanding the potential psychological and social impact of historical trauma on LGBTQIA+ individuals. Additionally, the development of a measure for LGBTQIA+ historical trauma may provide a valuable tool for clinicians and researchers aiming to address the unique mental health challenges faced by this community. By recognizing historical trauma as a factor in LGBTQIA+ health, interventions can be designed to foster resilience and mitigate the negative effects of systemic marginalization.
