Final answer:
Socioeconomic Status is not related to treatment attrition in sexual offenders according to the study by Olver, Stockdale, and Wormith (2011), whereas Motivation for Change, Severity of Offense, and Therapeutic Alliance are.
Step-by-step explanation:
In the study by Olver, Stockdale, and Wormith (2011), several variables were identified as related to treatment attrition in sexual offenders; however, Socioeconomic Status is not indicated to be one of these variables. The factors that do have a correlation with treatment attrition are Motivation for Change, Severity of Offense, and Therapeutic Alliance. These aspects have an impact on a sexual offender's likelihood to continue with treatment post-incarceration. Variables such as therapeutic relationships and the individual's own motivation to change are critical in determining treatment outcomes. Socioeconomic status, while impactful in different criminal justice contexts, does not directly correlate with treatment attrition according to this particular study.
