The impact of sexual abuse has been associated with a multitude of adverse consequences. As newer understandings on effective treatment methods emerge, treatment models are constantly being developed to adhere to best practice methods of reducing risk and recidivism. In clinical settings, Feedback Informed Treatment has been efficacious in reducing negative treatment outcomes. The Outcome Rating Scale (ORS) and Session Rating Scale (SRS) were subsequently developed for timely feedback collection in every treatment session. To investigate the utility of these scales in a sexual offending treatment context implementing the Good Lives Model-Comprehensive (GLM-C), 65 service users of a community-based treatment programme in Christchurch, New Zealand, completed the ORS and SRS in every individual session. As hypothesized, scores on both scales significantly increased over treatment (ORS effect size = .60, SRS effect size = .37). Those who did not complete the programme had lower rates of improved ORS and SRS scores (ORS: d = .70, SRS: d = .71), and those who were not cooperative with supervision had lower rates of improved ORS scores (η2 = .22). The average final ORS score and the average SRS change score had significant negative correlations with post-treatment dynamic risk scores measured on the Stable-2007. These findings suggest treatment for sexual offending implementing the GLM-C significantly improves well-being and therapeutic alliance as measured by the ORS and SRS, and higher well-being and improved therapeutic alliance are linked to favourable treatment outcomes in the form of lower dynamic risk.
