ONE SAMPLE WAS ALSO RATED FOR WARD BEHAVIOR BY NURSING STAFF, AND SIMILAR FACTORS EMERGED FROM THE BEHAVIOR RATING DATA. THE SELF-REPORT DIMENSION OF PSYCHOPATHY CORRELATED SIGNIFICANTLY WITH THE CORRESPONDING RATING DIMENSION AT THE TIME OF ADMISSION AND, FOR MEDICATED SUBJECTS ONLY, WITH RATING OBTAINED 2 YEARS LATER. CROSS-MEDIA CONVERGENCE OF THE WITHDRAWAL DIMENSION WAS NOT FOUND AT THE TIME OF ADMISSION, BUT FOR UNMEDICATED SUBJECTS, INITIAL SELF-REPORTS CORRELATED SIGNIFICANTLY WITH THE EQUIVALENT RATING DIMENSION AS ASSESSED 2 YEARS LATER. THE TWO DIMENSIONS THEREFORE APPEAR TO MEASURE MEANINGFUL BEHAVIOR DISPOSITIONS. WHILE THEY DEFINE THE SAME DIMENSIONAL SPACE AS NEUROTICISM AND INTROVERSION-EXTROVERSION, THEY APPEAR TO PROVIDE A MORE APPROPRIATE FRAMEWORK FOR CLASSIFICATION WITHIN THIS POPULATION OF OFFENDERS. TABLES, FIGURES, AND REFERENCES ARE PROVIDED. (AUTHOR ABSTRACT MODIFIED--PRG)
