Does Criminal Thinking Predict Prison Misconduct? An Evaluation of TCU’s Criminal Thinking Scales

Abstract

To date, only one published study has tested the predictive validity of the Texas Christian University–Criminal Thinking Scales (TCU-CTS), and no studies have tested whether these scales are predictive of prison misconduct. Using a sample of more than 2,000 people incarcerated in Minnesota’s prison system, this study examined the predictive validity of the TCU-CTS with multiple measures of prison misconduct. The results showed the overall TCU-CTS score significantly predicted misconduct, although the strength of this association was relatively modest (AUC = 0.62). Among the six scales on the TCU-CTS, Cold-Heartedness significantly predicted both measures of misconduct, whereas Power Orientation and Criminal Rationalization were each significantly associated with one misconduct measure.
