This report, Moving Beyond Change Efforts: Evidence and Action to Support and Affirm LGBTQI+ Youth, provides behavioral health providers, researchers, policymakers, and other audiences with current knowledge about LGBTQI+ youth, a comprehensive research overview, and important information on behavioral health concerns within this community. More specifically, the report provides details on helpful and harmful interventions for these populations in clinical, community, family, and school settings. In particular, the report documents that attempts to change an individual’s sexual orientation and gender identity (SOGI; pronounced “SO-gee” change efforts) are harmful and should not be provided. Additionally, this report discusses evidence-informed policy options that could improve the overall health and well-being of LGBTQI+ youth.
