Abstract
It is widely acknowledged that offender rehabilitation outcomes can be improved by attending to responsivity issues, including the readiness and motivation of offenders to undertake and engage in treatment. The measurement of responsivity, readiness and motivation in offenders, however, has received relatively little research attention. In this paper we focus on anger management programmes and evaluate the utility and psychometric properties of a measure of stages of change in relation to changing anger – the Anger Readiness to Change Questionnaire (ARCQ). Using data from a large sample of offenders undergoing anger management interventions, we investigated the construct validity, convergent validity and predictive validity of the ARCQ. We conclude the ARCQ may have utility as a measure for selecting offenders who are suitable for anger management interventions.
