Sociopolitical Trends and Attitudes Towards Transgender People: A Validation Study of the Transgender Knowledge, Attitudes, and Beliefs (T-KAB) Scale in a Portuguese Sample

Introduction: Attitudes towards transgender and gender diverse (TGD) individuals are associated with discrimination against TGD people and underly TGD minority stress. Despite Portugal’s progressive legal framework, anti-trans interactions and discourse are reported. Nonetheless, studies on trans attitudes are still incipient in Portugal. The Transgender Knowledge, Attitudes, and Beliefs (T-KAB) scale is a psychometrically sound measure of transgender attitudes. However, its convergent validity with transphobia is yet to be tested, and its ability to study sociopolitical factors driving pro-trans attitudes is unexplored. Methods: We explored the psychometric properties of the European Portuguese version of T-KAB in an online collected (February 2022 to May 2022) sample of Portuguese adults (N = 447), and tested differences (ANOVA; t-test) in T-KAB according to sociopolitical factors. Results: Results from the Principal Axis Factoring and Parallel Analysis showed a two-factor measure of acceptance, comfort, and social tolerance towards trans people. Both factors presented an excellent internal consistency (α =.94 and α =.95) and were significantly associated with the Genderism and Transphobia Scale. Conclusions: Results found that participants with a heterosexual orientation, less contact with TGD people, less educated, religious, and who endorsed a right-wing or conservative political ideology showed lower T-KAB scores. These results corroborate the psychometric validity of the T-KAB, as well as its ability to identify sociopolitical segments of the population according to their attitudes towards TGD people. Policy Implications: This study informs future research on tailored interventions to increase transgender acceptance, comfort, and social tolerance in the general population.
