Understanding criminals' thinking: further examination of the Measure of Offender Thinking Styles-Revised.

The Measure of Offender Thinking Styles (MOTS) was originally developed to examine the structure of dysfunctional thinking exhibited by criminal offenders. In the initial investigation, a three-factor model of criminal thinking was obtained using the MOTS. These factors included dysfunctional thinking characterized as Control, Cognitive Immaturity, and Egocentrism. In the present investigation, the stability of the three-factor model was examined with a confirmatory factor analysis of the revised version of the MOTS (i.e., MOTS-R). In addition, the internal consistency, test-retest reliability, and convergent validity of the MOTS-R were examined. Results indicated that the three-factor model of criminal thinking was supported. In addition, the MOTS-R demonstrated reliability and convergent validity with other measures of criminal thinking and attitudes. Overall, it appears that the MOTS-R may prove to be a valuable tool for use with an offender population, particularly because of the simple, intuitive structure of dysfunctional thinking that it represents.
