How can I summarize and rewrite with my own words?: From the factor analysis, it was showed that the TAI fitted two-Bifactor structure very well, the FAT and TAS moderately fitted four-Bifactor structure, and all of the three scales extracted a general factor- that was test anxiety. Besides, the correlations of test scores among three scales ranged from 0.5 (p < .01) to 0.6 (p < .01), which showed that the three scales measured the similar latent traittest anxiety. Based on the general factor-test anxiety, the psychometric properties of different self-report TA scales were further investigated
