Some problems on what sort of sub-factors composing of each dimension of the degree of delinquency （DD）should be selected by psychological specialists （PS）in the field of juvenile delinquency, were discussed.6 dimensions of DD were compared with each other by descriptive statistics, and 15 sub-factors belonging to each dimension were analyzed mainly by the principal component analysis（PCA）. On the base of those analyses, total 33 sub-factors selected from each dimension were finally subjected to PCA, and 8 principal components were extracted.Main findings based on above-mentioned analyses, were as follows;(1) PS laid stress on two dimensions of "criminal career" and "one's sense of value" in differentiating DD.(2) It was, however, found that 16 out of 33 sub-factors obtained from results of PCA, belonged to dimensions of "signs of delinquency" and "pre-delinquent behaviors", and that (3) 15 sub-factors belonging to the 1st principal component finally extracted by PCA, were all derived from two dimensions mentioned above, and were assumed to be named "over-active and glorious tendency".(4) These sub-factors could be observed objectively and collected easily, and be available in predicting delinquent behaviors.(5) We could prepare the Delinquency Scale equipped with both predictive and analytical functions, if we utilized results of this research.
