Numerous studies have been conducted over the last twenty years investigating the effectiveness of cognitive intervention programs on reducing reconviction rates among offenders. Whereas cognitive intervention programs have demonstrated promising results, there is a gap in the literature surrounding who would be most responsive. Knowing what type of offender would most benefit from attending this program could potentially reduce recidivism by providing the proper rehabilitation programming to offenders before they are released. The goal of this dissertation was to determine if significant change occurred by taking the revised Cognitive Intervention Program (CIP2) and to define characteristics that best predict success in CIP2 with improvement in criminal thinking and attitudes. Data came from secondary, archival data from students (n = 20,587) in the Windham School District in Texas that participated in the revised Cognitive Intervention Program (CIP2) in the first three (3) years of new program (August, 2016 through August, 2019).The analysis indicated CIP2 created reliable change in criminal thinking and attitudes for a significant number of individuals. Additionally, the decision tree analysis revealed the most important predictors for reliable change category on the measure of criminal thinking (MOCTS) were inmate type, gender, number of times in state jail, race, academic hours, age at start of CIP2, and TABE reading level. The most important predictors for reliable change category on the measure of criminal attitudes (MCAA) were age at start of CIP2, TABE reading level, total number of times in prison, and inmate type.
