This paper further explores the structure of moral personality traits, in order to develop scientific evaluation of moral personality traits. Using expert consultation and literature review to form the initial scale, after two times testing, the Chinese moral personality scale (CMPS) was formed. CMPS has two subscales (positive dimension and negative dimension), 16 items in each subscale, and 32 items in total. The results showed that, the scale accounted for 58.075% of the total variance, the coefficient of internal consistency of the whole scale is 0.957. The norm was established through a large sample size, and the results showed that the Chinese moral level ranged 95.84±5.04 (55.00±14.00 in positive dimension, 40.84±14.60 in negative dimension). There was no difference in the score (total score, positive dimension and negative dimension) of moral personality in gender, place of residence and education background. In positive dimension,age in 21-30 group ,more than 51 group and teacher were higher than other groups in age and occupation. In negative dimension age in 21-30 group and teacher were lower than other groups in age and occupation. In conclusion, CMPS has good reliability and validity and it is an effective tool to measure moral personality traits of Chinese.
