The purpose of this study is to construct and standardize the Five Factor Personality Inventory for Children (FFPC). Fifty items were chosen through two preliminary surveys. Then the 50-item questionnaire was administered to 3 386 primary school children. Based on the results of principal component analysis, 40 items were selected for the FFPC final version. The mean scores, standard deviations, and score distributions of the five-factor scales were computed. One sample of 215 children was tested twice, the interval being 9 weeks. The test-retest correlations ranged between .778 and .854. Scale scores correlated with teacher nominations of the various kinds of personality. The FFPC five-factor scales were shown to have high internal consistency and test-retest reliability. The factorial validity, construct validity, and concurrent validity were also confirmed.
