Abstract
This article examines the reliability and validity of the adaptation of the Trans Attitudes and Beliefs Scale (TABS), an instrument capable of detecting transphobic positions, to the Spanish context. A total of 829 psychology students participated in the adaptation procedure. A confirmatory factor analysis was performed to study the fit of the new scale to the factor structure of the original scale (interpersonal comfort, gender identity beliefs, and human value). Convergent validity evidence showed significant correlations and predictive levels with different constructs and sociodemographic variables. The internal consistency of the mean scores was adequate at the global level. The study showed that the TABS is a psychometrically sound instrument for the assessment of attitudes toward trans people, particularly in the context of debates over access to rights and the lack of professional training in disciplines such as psychology.
