Adding to the evidence base

Here at GIDS we are always thinking about the best way to support all young people who come to our service. Some of this thinking includes contributing to or being involved in research studies. Other ways that GIDS and the clinicians who work here add to the evidence base is through papers in medical journals or presentations at conferences. Below are some projects that are underway, and some that are completed.

We have linked to the items that are published, but some might be behind a paywall depending on the journal in which they appear.

We have added research in 2018 to this page, and will be working backwards to add previous years over the next few months.

Early intervention study

This study, currently underway, looks at psychosocial functioning, quality of life and treatment pathways after GnRHa pubertal suppression in young adolescents with gender dysphoria.

From the introduction to the study: “Pubertal suppression by means of gonadotropin-releasing hormone analogues (GnRHa) has gained increasing acceptance internationally as a recommended treatment option for young people of tanner stages two and over with gender dysphoria (GD), yet there is limited evidence of the psychosocial and physical outcomes of the treatment in this group. We prospectively evaluated the psychological, social and physical risks and benefits involved in pubertal suppression in a group of young people with gender dysphoria.”

The Longitudinal Outcomes of Gender Identity in Children (LOGIC) study

The Tavistock and Portman NHS Foundation Trust has been awarded £1.3 million by the National Institute for Health Research (NIHR) to carry out an independent study that will inform better, more individualised care for young people and their families struggling with issues relating to gender identity.

This new Longitudinal Outcomes of Gender Identity in Children (LOGIC) study is innovative and will include both quantitative and qualitative approaches. Uniquely, an independent team of researchers will follow a whole group of volunteer young people. The young people will be recruited from among those who have been referred to the Gender Identity Development Service (GIDS). The study will follow these young people, whether they remain in contact with NHS services or not, regardless of their path. This will allow the independent researchers to compare and investigate outcomes for the entire cohort, including both those who go on to use physical interventions (such as hormone blockers) and those who do not. The findings generated from this research will enable services to provide better care for patients and their families.
