THE STUDY INVESTIGATED THE EFFECTS OF SIX CORRECTIONAL INSTITUTIONS IN THE SOUTHWEST AND SOUTHEAST ON INMATE VALUES AND EXPECTANCIES OF PRIVACY. THE HYPOTHESIS WAS THAT DIFFERENCES IN INMATE VALUES AND EXPECTANCIES WOULD BE OBTAINED BASED ON THE DIFFERENT STRUCTURAL CHARACTERISTICS OF EACH INSTITUTION. PRIVACY WAS CONCEPTUALIZED AS SOLITUDE, INTIMACY, INDIVIDUATION, AND SELF-DISCLOSURE. INMATES SELECTED BY A STRATIFIED RANDOM-SAMPLING WERE ADMINISTERED A QUESTIONNAIRE OF 32 ITEMS WITH QUESTIONS RELATING TO BOTH EXPECTANCY AND VALUE. EFFECTS ATTRIBUTED TO GENDER WERE CONTROLLED. RESULTS SUPPORTED THE HYPOTHESIS THAT INDIVIDUAL NOTIONS OF PRIVACY VARY AS A FUNCTION OF ENVIRONMENT. SUPPORT CAME ALMOST ENTIRELY FROM THE EXPECTANCY SCALES, IN WHICH MANY OF THE OBTAINED DIFFERENCES WERE SIGNIFICANT. THE ONLY DIFFERENCES OBTAINED ON THE VALUE SCALES OCCURRED WITH INTIMACY, SUGGESTING THAT ONE'S EXPECTANCY FOR PRIVACY IS MORE SENSITIVE TO ENVIRONMENTAL VARIATIONS THAN ONE'S VALUE FOR PRIVACY. OVERALL, THE RESULTS DEMONSTRATE THAT INMATE PERCEPTIONS OF PRIVACY VARY AS A FUNCTION OF THE DESIGN AND ORGANIZATION OF THE INSTITUTION, ESTABLISHING A LINK BETWEEN THE PHYSICAL ENVIRONMENT AND THE INMATE'S PERCEPTUAL ENVIRONMENT.
