Applying the Good Lives Model to the Case Management of Sexual Offenders

A Practical Guide for Probation Officers, Parole Officers,
and Case Managers


by Mayumi Purvis, Tony Ward, & Simone Shaw


WP159 - GLM for Case ManagementThis book is about the case management of sexual offenders. It aims to explain how the Good Lives Model (GLM) can be effectively incorporated into case management work with sexual offenders and therefore forms a theoretical and practical guide for those correctional workers who wish to do so.

The authors helped implement a specialist case management model for sexual offenders at Corrections Victoria, Australia in 2008. From the very beginning, the organization was committed to the thorough and correct application of the GLM. On an ongoing basis, the authors have been working to constantly build and refine the GLM case management approach, based on the feedback and needs of Correction Victoria’s specialist case managers. This means that more than four years of theoretical and practical work has gone into the development of a GLM case management approach. The authors now feel that these practices, techniques, and tools should be shared with a wider audience. As such, the purpose of this book is to explain the core theories, principles, and practices that the authors believe should drive the case management of sexual offenders.
