The PMC system classifies inmates into one of five categories: selective intervention -- situational (SI-S); selective intervention -- treatment (SI-T); casework control (CC); environmental structure (ES); and limit setting (LS). Data were collected from records kept by the Research and Planning Section of Washington's Department of Corrections. Data included inmate characteristics (JU67W.DAT), work assignment records (JU68W.DAT), disciplinary records (JU69W.DAT), assignment records (JU70W.DAT), and housing assignment records (JU71W.DAT). Data were also collected from a long (JUnW.DAT) and short (JU73W.DAT) PMC questionnaire. Checks for out-of-range values revealed that the data are free of detectable coding errors. 1 I I GENERALSTUDYOVER~ I Source: I (1) Austin, J., Holien, D. A., Chan, L., & Baird, C. (1990).

I Study Identification Reducing Prison Violence by More Effective Inmate Management: An Experimental Field Test of the I Prisoner Management Classification (PMC) System James Austin I National Council on Crime and Delinquency Award No. B7-JJ-CX-0014 I KeyWords I Prison management, inmate violence, offender personality. I Purpose of the Study In Washington, the state selected for this study, the legislature passed legislation that increased the likelihood I and length of incarceration for persons convicted of violent crime. Because of longer sentences, violent offenders are increasing as a percentage of Washington's prison populat.ion. With more violent offenders in the prison population, concerns about the safety of inmates and prison staff emerge. The Prisoner I Management Classification (PMC) system was adopted from an offender management system developed originally in the late 1970s for probation and parole.
