Validation of the RAND Selective Incapacitation Survey and the Iowa Risk Assessment Scale in Colorado, 1982 and 1986

Published by National Institute of Justice | Department of Justice | Metadata Last Checked: June 25, 2025 | Last Modified: 2006-01-18T00:00:00
This data collection was designed to replicate the Rand Selective Incapacitation Survey and the Iowa Risk Assessment Scale using a group of Colorado offenders. The Iowa model provides two assessments of offender risk: (1) a measure of general risk to society and (2) a measure of the risk of new violence. The Iowa dataset includes crime information from defendants' self-reports and from official crime records. Both files contain important self-report items such as perceived probability of being caught, weapon used in the offense committed, months free on the street during the reference period, and detailed activity description during the free period. Other items covered include employment history, plans, reasons for committing the crime, and attitudes toward life, law, prisons, and police.
