Generalized stress and sleep hygiene explain the relationship between sexual/gender identity and sleep quality

IntroductionTypically, LGBTQ + people sleep more poorly than their cisgender heterosexual (cishet) counterparts. However, there is a lack of literature investigating the impact of different lifestyle/psychosocial factors, outside of minority stress, on the negative relationship between being a sexual/gender identity minority and sleep quality. The current study aims to help fill critical gaps in the literature by looking at the effects generalized stress, COVID-19-related stress, social support, and sleep hygiene have on this relationship.MethodsTwo hundred and seventy-three participants (74 LGBTQ+;199 cishet), recruited online, completed a series of questionnaires assessing sleep quality, sleep hygiene, generalized stress, minority stress, COVID-19-related stress, and social support.ResultsAnalyses showed that LGBTQ + participants reported worse sleep quality, higher levels of generalized stress and COVID-19 stress, and smaller social networks than their cishet peers. Generalized stress fully mediated the relationship between sexual/gender identity and sleep while sleep hygiene partially mediated the relationship between generalized stress and sleep quality. Social support and COVID-19-related stress did not moderate the relationship between generalized stress and sleep.ConclusionWorse sleep quality in LGBTQ + than cishet adults is explained by differences in generalized stress and sleep hygiene. Stress management and sleep hygiene interventions may help prevent the negative associations between being LGBTQ + and poor sleep quality.
