This book describes and examines five psychological systems for classifying adult male prison inmates: 1) Warren's I-level; 2) Megargee's MMPI-Based Criminal Classification System; 3) Hunt's Conceptual Level; 4) Quay's Adult Internal Management System; and 5) the Jesness Inventory Classification System. It also presents psychometric data on the reliability and validity of each system and illustrates different adjustment patterns of prison inmates.
Patricia VanVoorhis is Associate Professor of Criminal Justice at the University of Cincinnati.
"The prison population is growing dramatically, and, if administrators are going to try to accomplish anything beyond mere warehousing of inmates, they could use the information that this book provides. The study shows that the type of classification system needed may vary with the types of inmates and the organizational structures of the institutions. It also shows that a less complex classification model can be as accurate as a more elaborate model. Thus, efficiency of administration can be increased without sacrificing accuracy." — Peter C.
