The T-KAB (Clark and Hughto, 2020) is a 22-item, 3-factor measure representing: acceptance of the gender spectrum (ACC), social tolerance (ST), and comfort and contact (CC) related to transgender people. The total score (TOT) is the sum of it three sub-scales.
The adjusted T-KAB It is scored on a 6-point Likert scale (instead of the 4-point original) ranging from 1 ("Strongly disagree") to 4 ("Strongly agree"). An even-number scale was utilized to ensure that participants choose either agreement or disagreement, and thus, a neutral option was not included in the scale.
This results in an item-level score ranging from 1 to 6, and an overall TOT range from 22 to 132, with higher numbers representing better outcomes.
We changed the wording and reverse-scoring of 6 items, which due to double-negative wording, proved confusing in pilot testing. This resulted in 9/22 reverse-scored items (R), from the original scale with 15/22 R's.
