“…However, this is not the case. Although great advances have been made in our understanding of offender treatment and evidence for its effectiveness abounds (e.g., McGuire, 2002), critics remain suspicious about efforts to intervene in the lives of offenders (e.g., Israel & Chui, 2006;Merrington & Stanley, 2004;Wilkinson, 2005).
