Abstract

A validation study of Y·G personality test showed the following results. First, item analysis yielded a very high coefficient of reliability of 12 scales. The reliability was much improved if the scales were rearranged into groups. Second, factor analysis showed that the coefficient of factor congruence and correlation between the antithetical factors were very high and that the factor structure of the Korean was almost identical to that of the Japanese. Third, according to the results of structural analysis, 9 out of 12 scales were congruent structures, whereas C scale was semi-congruent structure, the R scale was similarity structure and the Ag scale was interaction structure. Thus the possibility of applying to both sexes of two countries was assured, although some items of the R scale and the scale level of the Ag scale should be reexamined. The above mentioned results affirmed the validity and reliability of Y-G personality test of a Korean version.
