AT ADMISSION THE WOMEN WERE GIVEN THE USUAL BATTERY OF ADMISSION TESTS PLUS A 24-ITEM SELF-CONCEPT SCALE. WHEN THE SAME TESTS WERE GIVEN 6 MONTHS LATER, GENERAL IMPROVEMENT WAS NOTED. THE WOMEN GENERALLY FELT THEY WERE MORE SKILLED, WERE MORE GOOD-LOOKING, WERE MORE RELAXED, AND WERE SMARTER. TEST ITEMS INDICATING THESE CHANGES ARE EXAMINED IN DETAIL AND THE FINDINGS ARE PRESENTED IN TABULAR FORM. ONLY ONE SCALE DECLINED; THE SUBJECTS WERE INCLINED TO VIEW THEMSELVES AS MORE LAZY AFTER 6 MONTHS. THIS IS CONSISTENT WITH THE NONPRODUCTIVE NATURE OF THE INCARCERATION SETTING. IT IS HYPOTHESIZED THAT THE NEWLY ADMITTED PRISONER IS IN A PERIOD OF LOW SELF-ESTEEM AND RETURNS TO HER NORM AFTER A PERIOD OF ADJUSTMENT. SOME OF THE CHANGE IS ALSO ATTRIBUTED TO THE ACTIVE EDUCATIONAL PROGRAMS IN THE INSTITUTION. REFERENCES ARE PROVIDED. (GLR)
