The Corrections Victoria Treatment Readiness Questionnaire (CVTRQ) scale itself exhibited good psychometric properties. It is internally consistent and has high levels of discriminant and convergent validity. The CVTRQ was able to predict treatment engagement and treatment performance at the mid-point of the program. It is concluded that the measure can play a valuable role in the assessment of offenders who are being considered for rehabilitative treatment. Although the needs to assess appropriate candidates for offender rehabilitation programs are widely acknowledged, few assessment tools are available that has been validated for use with offender populations. The objective of this study was to investigate the extent to which a self-report measure, the CVTRQ, validly predicted those offenders who were likely to be able to engage in a cognitive skills program. The CVTRQ is a 40-item self-report questionnaire that assesses readiness to participate in and engage with a cognitive skills training program. Participants in the study were 177 convicted male offenders referred to a cognitive skills program delivered in community and prison settings in Victoria, Australia. Tables and references
