THE PSYCHOLOGICAL TESTS UTILIZED IN THIS STUDY INCLUDED THE THREE PERSONS TEST, A SENTENCE COMPLETION TEST, AND A DRAWING TEST. THESE ALLOWED AN EVALUATION OF THE YOUTHS' FEELINGS OF PERSONAL VALUE, POTENTIALITY FOR CONTRACT, AND TIME PLACEMENT. RESULTS OF THESE TESTS WERE COMPARED TO THOSE OF A MATCHED CONTROL GROUP. THE RESULTS ARE PRESENTED ACCORDING TO THE AGE AND SOCIAL SITUATION OF THE SUBJECTS. IT WAS FOUND THAT DELINQUENT GIRLS MORE OFTEN HAVE A NEGATIVE IMAGE OF THEMSELVES THAN OTHER ADOLESCENT FEMALES; THAT THEY EXPERIENCE MORE FEELINGS OF REJECTION BY SOCIETY; THAT THEY ARE MORE OFTEN NARCISSISTIC AND REFUSE THE PAST MUCH MORE OFTEN THAN FEMALES FROM THE CONTROL GROUP; AND THAT OLDER DELINQUENT GIRLS AND THOSE IN INSTITUTIONS AT THE TIME OF THE TESTS SHOWED A WORSE IMAGE OF THEMSELVES THAN OTHER DELINQUENT GIRLS.
