[Personality, school-achievement and behavior disorders].

In the framework of the Basle Adolescence-Study, students with indications of behaviour disorders were the subject of a special analysis. The greater part of them belonged to the lower social class and frequented the intellectually less demanding branches of the school system. Even where this was not the case their personality profile showed the characteristics of the lower class populations. The theoretical base of the "labelling approach" could be verified. School and Counselling Service proved to be efficacious parts of the system of social control.
