The gender congruences and life satisfaction scale for transgender and gender-diverse youth (GCLS-Y): a validation study with samples from the UK and US

Abstract

Background There are currently no good quality psychometric tools available to assess multi-dimensional outcomes for trans and gender diverse youth. A tool is needed to develop a stronger evidence base regarding the evaluation of gender-affirming healthcare for the population. Aim The current study aimed to adapt and validate the Gender Congruence and Life Satisfaction Scale for young trans and gender diverse people (GCLS-Y) with young trans and gender diverse people aged 14-19 living in the United Kingdom (UK) and the United States (US). Method Initially, the GCLS-Y was adapted through expert consultation and discussion with trans and gender diverse youth to ensure it is meaningful and relevant. A survey that included the GCLS-Y and other psychometric measures that assessed gender incongruence, mental health and wellbeing to determine convergent validity and social desirability to examine discriminant validity was completed by 307 trans and gender diverse youth (n = 175 in the US and n = 132 in the UK). Findings Exploratory Factor Analysis supported a 5-factor model that was assessed as conceptually accurate. The final version of the GCLS-Y included 38 items with the following subscales: Psychosocial Implications of Gender Distress, Incongruence and Dysphoria related to Chest, Incongruence and Distress related to Genitalia, Social Perceptions of Gender, and Life Satisfaction. The measure was also found to be valid and reliable. Conclusions The GCLS-Y is a psychometrically sound tool that can be used to assess multidimensional outcomes among trans and gender diverse youth (14-19 years) related to mental health and wellbeing, gender incongruence and distress, and social experiences of gender. The tool can support the development of evidence-based policy, which has implications for legislation, healthcare funding, and broader societal attitudes.
