Studies have consistently shown that LGBTQ individuals are at increased risk for several mental and physical health challenges including suicidality. The relationship between religion and LGBTQ well-being in general and LGBTQ suicidality specifically has increasingly been the subject of scholarly investigation. This systematic review examines all peer-reviewed articles included in the EBSCO PsycInfo database since 2000 that examined the relationship between religiosity and LGBTQ suicide (50 studies in all). These studies reveal a complex relationship that is nuanced and, at times, contradictory. Overall, 65% identified at least one religiosity-related predictor as a risk factor for LGBTQ suicidality, 41% identified at least one religiosity-related predictor as a protective factor against suicidality, while 53% found no associations between religiosity-related predictors and suicide risk. However, when specifically examining religious affiliation/denomination, salience, or beliefs and behaviors, typically, religiosity was either protective or unassociated with LGBTQ suicidality. This held particularly true for studies that had population-based samples, employed control variables and included comparison groups, thus enhancing their generalizability. The one religiosity-related predictor that was almost universally identified as a risk factor was when an individual felt conflicted between their religious and sexual-gender identities.
