Objectives. The aim of the study was to investigate socio-demographic andpsychopathological determinants of aggressive behaviors in male residents of a juvenile correctional center, and to assess their aggression level.
Method The subjects were compared with junior high school students enrolled as the controls. The Buss-Durkee Scale was used to assess various forms of aggression, and a sociodemographic ąuestionnaire developed by the authors - to collect personal data. Moreover, mental condition was evaluated in both groups.
Results. A majority of the correctional center residents had a working-class background. The main source of their family income included various forms of social benefits (unemployment compensation, alimony old age or disability pensions), and they mostly rated their material situation as bad or very bad. Approximately 50% of the controls had a white-collar background, 95% of theirparents were employed, and the material situation of the family was perceived as very good by over a half of the group. All the boys from the juvenile correctional center manifested behavior disorders. In some cases also otherpsychopathological conditions were diagnosed. On the other hand, no conduct abnor-malities were found in the control group of junior high school students.
Conclusions. In the study group of correctional facility residents the aggression level was higher than that among the controls. The difficult background socio-economic conditions of the former could have intensified their family problems, affecting in turn their psychophysical development. Their scholastic difficulties, environmental neglect, a sense of rejection by the family and relatives might intensify their aggres-sion and make them seek groups that would accept such behaviors.
