Abstract: In this research, based on the parents' free description, four personality questionnaires(3, 6, 9, 12 years) were developed and employed on 777 3-12-year old children in Beijing and Fuzhou city. The results indicated that the four questionnaires had good validity and reliability. After factor analysis(PCA, principal compoment analysis) to four questionnaires in four age groups separately, the main personality dimensions over the factor structure of 3 to 12-years old groups were named as:"Intellect", "Conscientiousness", "Agreeableness"," Extraversion", "Emotional Stability"and "Autonomy". Among them, "Intellect" was the most stable dimension in the four age groups, "Agreeableness", "Extraversion" and "Conscientiousness" followed."Emotional Stability" was not a stable dimension in Chinese personality structures.Moreover, the content of the six dimensions were consistent with the first six (sub)categories of "14 Categories System for Personality Coding Descriptors", and the first five dimensions were consistent with adult Big Five faCtors (or sub-factors). The results showed that there were rationally resembleness betWeen Chinese children's personality structures and the Big five factors in adult Personality psychology. On the other hand, there were strong age and culture specificity in the personality dimensions of the four age groups, and it indicated that the dimensions can cover the specific personality characteristics of Chinese children.
