Utrecht Gender Dysphoria Scale - Gender Spectrum (UGDS-GS): Construct validity among transgender,nonbinary, and LGBQ samples

Abstract

Background: Researchers combined both versions of the original Utrecht Gender Dysphoria Scale (UGDS) to create a single gender spectrum version (UGDS-GS) which measures dissatisfaction with gender identity and expression over time as well as comfort with affirmed gender identity.

Aim: This study examined the construct validity of the newly revised, UGDS-GS.

Method: Tests of measurement invariance were conducted in stages to assess measurement invariance of the UGDS-GS across three groups: cisgender, binary transgender, and nonbinary/genderqueer.

Results: Findings indicate that the UGDS-GS functions acceptably in all three gender groups (configural and metric invariance). Also, across binary transgender and nonbinary/genderqueer groups, the measure functions very similarly with all four types of invariance. Item level findings highlight the specificity of the measure to distinguish experiences of binary transgender and nonbinary/genderqueer persons differently from cisgender LGBQ individuals.

Conclusions: The UGDS-GS demonstrates a large degree of invariance across binary transgender, nonbinary/genderqueer, and cisgender LGBQ subgroups; and therefore, findings indicate this revision to be a substantial improvement. This 18-item self-report, Likert-type scale measure is a) inclusive of all gender identities and expressions (e.g., transfeminine spectrum, transmasculine spectrum, genderqueer, nonbinary, cisgender); b) appropriate for use longitudinally from adolescence to adulthood; and c) administered at any point in the social or medical transition process, if applicable, or in community-based research focused on gender dysphoria that examines cisgender and transgender persons.     

Correlates of unhealthy weight-control behaviors among adolescents: implications for prevention programs.

This study aimed to identify correlates of unhealthy weight-control behaviors in adolescents to guide the development of programs aimed at the primary prevention of disordered eating. A model explaining unhealthy weight-control behaviors was tested among 4,746 adolescents using structural equation modeling. Models fit the data well and explained 76% of the variance in unhealthy weight-control behaviors among girls and 63% among boys. Weight-body concerns were a strong correlate of unhealthy weight-control behaviors in both girls and boys. Models also emphasized the importance of weight-specific social norms within the adolescent's proximal environment. Findings suggest the importance of addressing weight-body concerns within prevention programs and extending interventions beyond classroom settings to ensure changes in weight-related norms among peer groups and family members.
