AN EXAMINATION WAS MADE OF THE VARIOUS PATTERNS OF INTERPERSONAL BEHAVIOR OF YOUTHS WHICH DISTINGUISH DELINQUENTS FROM NONDELINQUENTS. THREE GROUPS WERE EMPLOYED IN THIS STUDY. GROUP ONE CONSISTED OF IDENTIFIED DELINQUENTS. GROUP TWO CONSISTED OF UNBEARABLE YOUNGSTERS AS DETERMINED BY THE TEACHER. GROUP THREE CONSISTED OF A MATCHED CONTROL GROUP. THE SUBJECTS WERE SELECTED FROM THE LOCAL JUNIOR HIGH SCHOOLS. THE RANGE OF DATA AND RESPONSES VARIED BETWEEN 135 TO 168 SUBJECTS. THE ACTIVITIES INDEX WAS ADMINISTERED TO ALL SUBJECTS. INFORMATION WAS ALSO OBTAINED FROM QUESTIONNAIRES SENT TO THE TEACHERS. INTERVIEWS WITH THE PARENTS, AND THE SUBJECTS'"LIFE CARDS." ANALYSES OF DATA WERE MADE USING CHI-SQUARE PROCEDURES. THE GENERAL FINDINGS SUGGESTED THAT DELINQUENT AND UNBEARABLE SUBJECTS WERE NOT THE SAME. ALSO THE DISTANCE BETWEEN THE DELINQUENT AND THE PARENT INDICATED THE HOSTILITY WAS DIRECTED AGAINST THE ENTIRE SOCIETY AND NOT JUST THE SCHOOLS. FURTHER INVESTIGATION WAS SUGGESTED ON THE RESPONSE OF THE TEACHERS TO SUCH BEHAVIOR AND THE DIFFERENCES IN HANDLING THE DELINQUENT AND UNBEARABLE-TYPE STUDENTS. (RS)
