The Being LGBTQI+ in Ireland study is a sequel to the 2016 LGBTIreland study which highlighted that although many of the participants within LGBTQI+ communities were experiencing positive wellbeing, a sizable minority were experiencing high levels of mental distress and mental health challenges. Given the many developments that have taken place since its publication, it was considered timely to track potential changes since 2016. Similar to LGBTIreland, the Being LGBTQI+ in Ireland study consists of two Modules with a complementary focus. Module One focussed on the mental health of the LGBTQI+ community and collected data from over 2,800 LGBTQI+ people living in Ireland. In addition to tracking changes to mental health and wellbeing eight years on, positive experiences as well as issues of safety, discrimination, media, school and health care utilisation were explored. Module Two focussed on attitudes of the general public in the Republic of Ireland towards LGBTQI+ people. It consisted of two nationally representative surveys with approximately 1,000 people in each; one administered through a telephone interview, and one administered online.
