Correctional facilities are increasingly burdened with mentally disordered offenders and are faced with the formidable task of effectively screening inmates for major mental disorders and suicide potential. Teplin and Swartz (1989) developed the Referral Decision Scale (RDS) as a rapid screen for schizophrenia and major mood disorders in jail populations. However, more recent research by Hart, Roesch, Corrado, and Cox (1993) has called into question the effectiveness of the RDS. In this study, we examined the convergent and discriminant validity of the RDS with the Schedule of Affective Disorders and Schizophrenia—Change Version (SADS-C) and the Personality Assessment Inventory (PAI) on a sample of 108 mentally disordered inmates. The RDS provided moderate evidence of convergent validity but failed to demonstrate acceptable discriminant validity, because of high intercorrelations on RDS subscales (heterotrait-monomethod coefficients). In comparison, the SADS-C yielded similar evidence of convergent validity and excellent discriminant validity.The authors would like to thank the Research Opportunities Program, University of North Texas for its grant support and Captain James Moore for his active cooperation.Tarrant County Mental Health and Mental Retardation Services.  相似文献

Congress and the Drug Enforcement Administration have assigned certain psychoactive substances to one of five schedules, based on assumed or demonstrated abuse potential. Although formidable difficulties exist in assessing the hazards of drug use, some of these assignments do not appear consistent with empirical estimates. This mismatch of assignment and abuse potential -possibly due to "radical" political ideology - obscures significant differences in drug effects, and therefore stifles meaningful public participation in evaluating the benefits, risks, and proper use (if any) of available psychoactive substances.  相似文献

Although past research has developed scales for the incidence, prevalence, and fear of student-on-student victimization (SSV), little is known about the scaling of perceived risk (i.e., the cognitive appraisal of the chances of experiencing SSV). Hence, this study examined self-report survey data for the perceived risk of SSV as measured in the Adolescent Index for School Safety (AISS). Children in grades 7 through 10 (n=337) in a single Florida public school completed the AISS. Factor analyses using Maximum Likelihood Estimation with Oblimin Rotation identified nine unique factors for perceived risk. Reliability analyses found standardized Cronbach Alphas that ranged from .64 to .91, and seven out of the nine identified scales were above .80, which suggested good to excellent internal consistency. Future research should examine the content validity, construct validity, and predictive validity for the AISS and other self-report surveys of SSV dynamics. This publication was made possible by a grant [#97-MU-FX-KO12 (S-l)] from the Office of Juvenile Justice and Delinquency Prevention (O.J.J.D.P.), United States Department of Justice (U.S.D.O.J.). This grant is administered through the Hamilton Fish National Institute on School and Community Violence at George Washington University. This specific study was developed and implemented by staff at: 1) East Carolina University’s Department of Criminal Justice; and 2) Florida State University’s Center for Educational Research and Policy Studies. All points of view and opinions in this paper are those of the authors and do not necessarily represent the official position or policies of East Carolina University, Florida State University, the Hamilton Fish National Institute on School and Community Violence, the O.J.J.D.P., or the U.S.D.OJ. The authors would also like to thank Dr. Bill Doerner and Jennifer Jolley for their support, editorial feedback, and insightful comments regarding earlier drafts of this paper.  相似文献

Seit längerem ist in Rechtsprechung und Literatur umstritten, 1 ob und in welchem Umfang ein Insolvenzverwalter wegen Gefahren, die von Massegegenständen ausgehen, ordnungsrechtlich haftet. In zwei aktuellen Urteilen hat das BVerwG eine Zustandsverantwortlichkeit des Insolvenzverwalters grundsätzlich anerkannt. Insbesondere durch Freigabe von Massegegenständen kann sich der Insolvenzverwalter aber von der ordnungsrechtlichen Haftung befreien. 1) Vgl. zu dem Streit zwischen Insolvenz- und Verwaltungsrechtlern, Verwaltungs- und Zivilgerichten: Uhlenbruck KTS 2004, 275ff.; Kothe ZfIR 2004, 1ff.; Häsemeyer in: FS Uhlenbruck, 2000, S. 97ff.; Franz NuR 2000, 496ff.  相似文献
