Confirmatory Factor Analysis of the Transgender Knowledge, Attitudes, and Beliefs (T-KAB) Scale for the Mexican Population

Creating the Chinese version of the transgender attitudes and beliefs scale

BACKGROUND

Trans persons' physical and mental health is easily affected by the attitude of those around them. However, China currently lacks a valid psychometric instrument to investigate people's attitudes toward trans persons. Therefore, this study modifies the English version of the Transgender Attitudes and Beliefs Scale (TABS) to suit the Chinese context. It subsequently examines the reliability and validity of the Chinese version of the TABS.

METHODS

This study recruited 1164 university students, aged 18-25 years, from 7 regions of China. SPSS26.0 and AMOS24.0 were used for data statistical analysis. Critical ratio method and correlation coefficient method were used for item analysis. Exploratory factor analysis and confirmatory factor analysis were used to test the structural validity of the Chinese version of Transgender Beliefs and Attitudes Scale, and the internal consistency reliability of the scale was tested.

RESULTS

The TABS-C contains 26 items with 3 factors. The Cronbach's alpha was 0.957 for the total scale and 0.945, 0.888, and 0.885 for the 3 factors. The half-point reliability of the scale was 0.936, and the retest reliability was 0.877. The Pearson correlation coefficients for the 3 factors and the total scale score ranged from 0.768 to 0.946.

CONCLUSION

The TABS-C has reliable psychometric properties and is suitable for usage among college students in the Chinese context.

Transgender Attitudes and Beliefs Scale-Greek (TABS-Gr) version: translation and initial evaluation of psychometric properties among medical students

BACKGROUND

Transgender people face significantly greater discrimination and health disparities in health care settings than cisgender people. The role of education in eliminating this phenomenon has been increasingly recognized by many medical schools. However, transgender health content is sparse or lacking in the medical curricula of many countries.

METHOD

This study was designed to validate the Greek version of the Transgender Attitudes and Beliefs Scale (TABS-Gr). The study adopted a cross-sectional, comparative-descriptive research design. Participants (N = 203) were contacted through online recruitment and invited to complete an anonymous web-based survey. The data were collected between December 2022 and February 2023.

RESULTS

The overall reliability of the TABS-Gr questionnaire was high (Cronbach's α = 0.961, p. from Hotelling's T-squared test < 0.000). High Cronbach's alpha values were estimated for the three subscales, with α = 0.958 for Interpersonal Comfort, α = 0.906 for Gender Beliefs, and α = 0.952 for Human Values. Hotelling's T-squared test confirmed that all items on the scale had the same mean (p < 0.001 for all subgroups). Explanatory factor analysis (EFA) demonstrated adequate fit. Convergent and discriminant validity were validated based on the estimated correlations. The three-factor structure of the Greek TABS version was confirmed. The mean total score was 155.95 (SD = 30.63), indicating that medical students had a moderately positive attitude towards transgender people. Participants showed significantly less biased (more tolerant, positive) attitudes towards transgender people on the Interpersonal Comfort (IC) and Human Value (HV) subscales than on the Sex/Gender Beliefs (SGB) subscale. A demographic comparison was conducted and demonstrated a correlation between scores and sociodemographics, except for place of origin. A statistically significant increase in the total mean score was estimated for women compared to men.

CONCLUSION

The overall psychometric findings provide some evidence to support the validity of the Greek version of the TABS. However, we call for further validation research in Greek medical schools. Since our claims for validity are based in part on an exploratory factor analysis, a future confirmatory factor analysis (CFA) is part of our call for further validation research. While the results of this study are mostly in line with the results of previous research, some nuances were identified. These results may inform educators, medical school curricula and education policy-makers.
