The presenters will discuss using positive psychology within a transgender and gender diverse population and present their findings from an international quantitative study published in a psychology peer review journal in 2019. Societal transphobia detrimentally impacts the mental health of transgender and gender diverse (TGD) people. Currently clinical psychology has focused on the diagnosis and treatments of gender dysphoria. However, an unintended consequence of the current approach is the creation of a deficit model that pathologises TGD identities, ignoring the possibility that TGD identities can have strengths. The aim of this study is to explore character strengths in TGD people. The psychometric properties of the Values in Action (VIA) Classification of Strengths were evaluated in relation to its use with transgender (trans) and gender diverse (TGD) people. 150 transmen, 150 transwomen, and 150 gender nonbinary people matched by age (18 to 63 years of age; M = 29.7, SD = 9.9) and of similar ethnicity and nationality completed the 192-item VIA-IS-R. Confirmatory factor analysis of responses supported a modified three-factor model consisting of three higher order ‘virtues’ – inquisitiveness, caring, and self-control. The model demonstrated adequate convergent and discriminant validity as well as measurement invariance (configural, metric and scalar) across the three TGD groups. Construct validity was supported by multiple regressions showing that the virtues explained significant variance in self-perceived resilience and, to a lesser extent, trans-specific positive measures. These results suggest that with modification, the VIA-IS-R is suitable for use with gender diverse people.
