Improving Prison Classification Procedures in Vermont: Applying an Interaction Model, 1983-1985 (ICPSR 8933)
Principal Investigator(s): Apao, William K.
Summary: The purpose of this data collection was to develop and test an interactive model for classifying prisoners. The model includes person variables, environmental or situation variables, and prison-environmental interaction variables in order to study the interactions between individuals and their environments and to predict offender behaviors such as escape, misconduct, and violence. The model was designed to enhance the predictive validity of the National Institute of Corrections' clas... (more info)

Scope of Study
Summary: The purpose of this data collection was to develop and test an interactive model for classifying prisoners. The model includes person variables, environmental or situation variables, and prison-environmental interaction variables in order to study the interactions between individuals and their environments and to predict offender behaviors such as escape, misconduct, and violence. The model was designed to enhance the predictive validity of the National Institute of Corrections' classification system that was being used in Vermont prisons. Included are scores from the National Institute of Corrections' custody classification and reclassification instruments, scores from a needs assessment, sentencing information, and characteristics of the prison in which the inmate was housed.
