BACKGROUND: LGBTQI+ individuals appear to be particularly at-risk of exposure to interpersonal violence. This leads to an increased risk of developing symptoms of Post-Traumatic Stress Disorder (PTSD) or Complex Post-Traumatic Stress Disorder (C-PTSD). The objectives of this systematic review is to: (1) Compile the prevalences of PTSD/C-PTSD among LGBTQI+ individuals; (2) Compare the symptomatology of PTSD/C-PTSD according to sexual orientation and gender identity; (3) Identify the factors involved in the symptomatology of PTSD/C-PTSD among LGBTQI+ individuals.
METHODS: A systematic literature review was conducted on PTSD/C-PTSD among LGBTQI+ individuals. Psychinfo, Psycharticle, Psychology and Behavioral Sciences Collection, Embase, and LGBTHealth databases were queried. Only quantitative, observational studies based on data collected after 2010 and involving LGBTQI+ adults were included. The risk of bias was assessed using the Control Guidelines Critical Appraisal Toolkit developed by the Public Health Agency of Canada.
RESULTS: Out of the 7446 articles identified, 60 were included. Eighteen provided data on prevalence, and 57 on associated factors. The majority of studies were conducted in the United States. The vast majority of studies assessed PTSD using self-administered scales. Only one evaluated symptoms of C-PTSD. All included studies reported extremely high PTSD prevalence rates, with certain populations appearing particularly at risk, such as bisexual (10.3-35.7% PTSD) and transgender individuals (36.8-64.3% PTSD). Individual (e.g., financial precarity, transition, internalized stigma), interpersonal (e.g., outness, social support), organizational (e.g. health barriers), community (e.g. anti-trans discourse), and political variables (anti-trans laws project) associated with PTSD/C-PTSD symptoms have been identified.
CONCLUSIONS: The results show the importance of considering PTSD/C-PTSD among LGBTQI+ individuals in clinical practice and research. Higher quality studies are needed to quantify the extent of the problem. Healthcare professionals must be trained in the specific factors that may contribute to PTSD/C-PTSD symptoms in LGBTQI+ individuals. This cannot be achieved without public policies aimed at preventing all forms of violence against the LGBTQI+ population and ensuring access to equal rights.
