Results : The mean scores of MtFs were higher than the male normals in all 10 clinical factors of the MMPI, and the differences were significant (P<0.01 or P<0.001). Both the Mf and D factors exceeded the clinical threshold (T>60) and were the highest and second highest in the entire scale profile; FtMs were significantly higher than female normals in Hy, Pd, and Ma (P<0.05, P<0.01 or P<0.001); There was a significant difference in the detection rate of abnormal values of different factors of MMPI (T>60) in gender, age and education (P<0.05, P<0.01 or P<0.001). Conclusion : MtFs may have a variety of psychological distress, especially the need to focus on the primary education, 25 years old and below the transgender female personality psychological development.
