さきに著者が発表した,K.K.改訂Bemreuter Personallty Inventoryを,中学生の生活や思考に適応するようにあらためた92項目の診断目録(K.B.P.I、-J特型)を作製し220名の被検者の応答に基づいて,各項目間の四分割相関係数を算出し,その相関行列をもとに三因子分析を行ない,7個の因子を抽出した。それはもとの診断目録の因子と5個一致し,2個はもとの因子とは別のものと解釈された。一致した因子は,神経質,自己充足・内向-外向,自信欠如・支配服従1の5特性であり,もとのB.P.I.にあつた社交性のかわりに,情緒性,自我の2特性が抽出された。次に各因子の各項目に対する負荷量を5段階法によって,重みづけを行をつて,2,1,O,-1,-2の得点をあたえた。次に中国・四国,近畿地区のづ・学校5年生以上高等学校1年までの児童,生徒約1,000名に,この診断目録を実施して,その標準化を行をつた。因子解釈において,特にS型との関連において,やや困難を感じさせられたものが若干あり,目録の妥当性についての検討が,今後に残された課題である。

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, l, O, -1, and -2, according to the 10adings. 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.
