Effect of test administration set on the Psychological Inventory of Criminal Thinking Styles (PICTS).

The Psychological Inventory of Criminal Thinking Styles (PICTS) was administered to 160 male prisoners on admission to a medium-security federal correctional facility. A total of 106 of these inmates completed the PICTS a second time 6 months later in a routine follow-up of the intake PICTS; the other 54 inmates completed the PICTS a second time approximately 6 months later during the initial session of a psychological group. Results showed that inmates participating in the psychological group were less defensive and endorsed more criminal thinking items on the second administration of the PICTS, whereas inmates participating in the routine follow-up were more defensive and less likely to endorse criminal thinking items on the second PICTS. Despite a general increase in the magnitude of PICTS scores for program participants, the overall pattern of scale elevations (correlations between scales and high-point pairs) was comparable across the two groups.
