Abstract
The purpose of this study was to see whether or not the six factors of the Bernreuter Personality Inventory were applicable to Japanese juveniles, and to standardize the inventory with Japanese pupils.
In order to adapt the inventory to Japanese pupils, we have modified some of the items, and decreased the number to 92 items. We have administered the inventory to 220 junior high school pupils, and we have calculated the 4186 tetrachoric correlations between the responses to each of the 92 items. By factor-analyzing the matrix of the correlations by the centroid method, we have extracted seven factors. The axes of the factors were rotated, and each factor was interpreted. Though five of them concided with the original factors of the Bernreuter Personality Inventory, we could not find the factor corresponding to the F-2 Sociability. Instead, we have found two other factors, to which we have named the Emotionality, and the Egostrength factors.
The loadings of the factors to each item were weighted by using a five point scale, and given scores of 2, 1, 0, -1, and -2, according to the loadings.
The sample of standardization consisted of about one thousand pupils from fifth grade to tenth grade (including elementary schools, junior high schools and senior high schools) of the Kansai and the Chugoku districts. The means, the S. Ds., and the percentile scores of the seven traits were calculated.
