Purpose and Methods: The purpose of this study is to clarify the characteristics of ideal self-image of juvenile delinquents, by means of Q-sorts. Q-sort cards used here, consist of 40 self-referent statements, and subjects are requested to classify cards in accordance with the likeliness to their ideal self-image.

Subjects: Delinquents (Group D)………174boys admitted into juvenile reform and training school. Age 14-19 Mean IQ=95 Non-Delinquents (Group ND)………133 boys in the training course of an electric power company. Age 15-18 Mean IQ=115

Results: (1) The appraisals to each statement between two groups are same for the emotional traits but not for the social traits.

(2) The correlations of ideal self-image are very high between each member of Group ND, but very low between each member of Group D.

The results of this study suggest that the value system of juvenile delinquents is very different one another.

In Japan, the problem of how to treat traffic offenders becomes one of the main topics of penal system, as the traffic accidents increase. This study aims at the classification of traffic offenders, from the stand-point of treatment, and suggesting the effective program in treating them in prison settings.

Subjects; Traffic offenders sent to Nakano Prison (Tokyo) from June to August, 1967.

N=124

Methods; (1) Subjects took such psychological tests as Intelligence Test, Driving Aptitude Test Batteries, (made by the Scientific Police Research Institute of Japan), and Driving Attitude Survey (made by Aoki & Sogo).

(2) The official records were examined.

(3) Subjects were classified into three groups according to the following;

Group I (1) Mentally and physically handicapped.

(N=22) (2) Not qulified according to the Driving Aptitude Test Batteries.

Group II (1) Usually driving recklessly and thoughtlessly.

(N =43) (2) Problem drivers according to the Driving Attitude Survey.

Group III Not classified into Group I or II.

(N=57)

These groups are reffered to the categories of “Can’ts”, “Won’ts,,, and “Don’ts” set by Economos, J. P. and Williams, S. J., while the method of our classification is rather operational.

(4) The awareness of the causes of accidents of subjects and the foresight of their future life were compared between these three groups.

Results; Results were as follows…………

Two-thirds of the Group I is not aware of their disability for driving. So the vocational guidance is nessesary for the members of Group I.

Most of the members of the Group II have psychological problems in personality. So they must be undergone the psychological counseling or psychotherapy.

The members of Group III have problems in the unskilled driving and the lack of knowledge. So the treatment of them should be focused to the re-education of driving skills.
