Conversion practice recall and mental health symptoms in sexual and gender minority adults in the USA: a cross-sectional study

Conversion practices are associated with psychological morbidity, yet few studies have evaluated differences between efforts to change gender identity, sexual orientation, or both. We aimed to examine the individual and joint association of conversion practice recall targeted at gender identity or sexual orientation, or both, with current mental health symptoms among sexual and gender minority people. This cross-sectional study used data from The PRIDE Study, a US-based, online, prospective cohort study of sexual and gender minority adults who were recruited through social media, digital advertisements, and sexual and gender minority community-based events and organisations. For this analysis, we included participants who completed a lifetime questionnaire in 2019–20 and a subsequent annual questionnaire in 2020–21 without missing outcome data. All questionnaires were in English. The exposure was lifetime recall of conversion practice targeting gender identity alone, sexual orientation alone, or both (versus no conversion practice). Mental health outcomes were continuous measures: Generalized Anxiety Disorder 7-item scale, Patient Health Questionnaire 9-item (depression) scale, Post-Traumatic Stress Disorder Checklist 6-item scale, and Suicide Behaviors Questionnaire–Revised scale. We used linear regression to analyse the associations of conversion practice recall and mental health symptoms, controlling for demographic and childhood factors and stratified between cisgender and transgender and gender diverse groups. Sensitivity analyses evaluated the potential impact of unmeasured confounding. Analyses were conducted in R. We included people with related lived experience in the design and implementation of this study. Of 6601 participants who completed the lifetime questionnaire in 2019–20, 4440 completed the subsequent annual questionnaire in 2020 or 2021, and 4426 did not have missing outcome data. Of the 4426 included participants, 4073 (92·0%) identified as White (either alone or in combination with other ethnoracial options), 460 (10·4%) identified with multiple ethnoracial identities, and 1923 (43·4%) were transgender and gender diverse. Participants' age ranged from 18 years to 84 years (median 31·7 years, IQR 25·5–44·1). 149 (3·4%) participants reported sexual orientation-related conversion practice alone, 43 (1·0%) reported gender identity-related conversion practice alone, and 42 (1·0%) reported both.
