An Offender Version of the Working Alliance Inventory-Short Revised

Abstract

The series of Working Alliance Inventories remains the most extensively researched and utilized instruments to measure the working alliance. However, these instruments have not been normed and validated among individuals on probation or parole. Therefore, this study provides psychometric properties for a modified, offender version of the Working Alliance Inventory-Short Revised (WAI-SR) with a sample of individuals on probation and parole. Results reveal that a single factor model should be used with an offender population. Results also indicate the WAI-SR has strong reliability and validity with this particular population.
