Psychometric Evaluation of the Transgender Congruence Scale

Introduction: Despite increased attention to transgender and gender diverse (TGD) issues in psychological literature during the past decade, gaps remain for psychometric validation of TGD-specific measures. Kozee et al. (Psychology of Women Quarterly 36(2):179–196, 2012) addressed such gaps by creating the Transgender Congruence Scale (TCS), measuring gender acceptance and feelings of gender congruence between internal and external attributes across a broad range of gender identities. The current study extended Kozee and colleagues’ work by further examining the psychometric properties of the TCS. Methods: Between October and November of 2017, 210 transmasculine, transfeminine, and gender diverse adults between ages 19 and 73 completed online surveys containing demographic, gender identity-specific, and well-being measures including the TCS. Results: Results of confirmatory factor analysis replicated the original two-factor model (Appearance Congruence and Gender Identity Acceptance), with the elimination of two poorly loading items, resulting in a 10-item reduced model (TCS-10). Higher scores on TCS-10 were associated with positive scores on gender-related well-being, congruence, and pride, positive affect, and life satisfaction, as well as lower scores on gender-related dysphoria, non-affirmation, internalized transphobia, and marginalization. There were modest but significant associations between Gender Identity Congruence and both depression and negative affect. Conclusions: Despite limitations of sample size and diversity of identities, the study reaffirmed the utility of the TCS as an overall construct of gender identity congruence with a 10-item reduced structure related to other established TGD constructs. Policy Implications: Though socio-political climate is the ultimate domain for alleviating TGD stigma and discrimination, factors such as gender congruence are essential areas of focus to foster resiliency.
