The Psychological Inventory of Criminal Thinking Styles (PICTS) was administered

to 207 male federal prisoners enrolled in a 10-week program of psychoeducation. Compared with inmates who completed the course, dropouts (n = 16) scored higher on seven of the eight PICTS thinking style scales, with differences on three of these scales (Mollification, Cognitive Indolence, and Discontinuity) achieving statistical significance. A multivariate composite of the eight thinking style scales proved signif-icant, and the PICTS achieved significant predictability even after controlling for basic demographic measures such as age, education, ethnic status, marital status, and instant offense. Although a low base rate of discontinuation in the present sample (7.7%) made predicting program completion impractical, the PICTS may still help clarify the motives of incarcerated offenders who prematurely terminate psychoedu-cational programming
