This study sought to determine whether criminal thinking possessed by offenders in prison would be significantly reduced through the implementation of motivational curriculum amid a broader menu of treatment and educational programming. This study utilized the Criminal Thinking Scale (CTS) as a pretest and posttest measure of criminal thinking among offenders who participated in the array of programs offered. Results between both measures of the CTS showed significant reductions in criminal thinking. Further analysis related to reductions in subscale measures is also discussed in this study.
