The LGBTQ Supportive Environments Inventory: Methods for Quantifying Supportive Environments for LGBTQ Youth.

The social environment in which lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth live influences health and wellbeing. We describe the development of the LGBTQ Supportive Environments Inventory (LGBTQ SEI), designed to quantify the LGBTQ-inclusiveness of social environments in the US and Canada. We quantify aspects of the social environment: 1) Presence/quality of LGBTQ youth-serving organizations; 2) LGBTQ-inclusive Community Resources; 3) Socioeconomic and Political environment. Using GIS tools, we aggregated data to buffers around 397 schools in 3 regions. The LGBTQ SEI can be used to assess the role of the social environment in reducing health disparities for LGBTQ youth.
