Abstract
The first objective of this study was to determine whether the Psychological Inventory of Criminal Thinking Styles (PICTS) General Criminal Thinking (GCT) score correlated negatively with program completion in a group of 199 (123 male, 76 female) day treatment clients across several different levels of defensiveness. The second objective was to ascertain whether the GCT continued to predict program completion in a logistic regression analysis when age, sex, race, educational level, marital status, drug offense, and prior arrests were controlled. Results indicated that while the GCT did not predict program completion in the full sample, it did so when clients with moderately high to very high scores on the PICTS defensiveness-revised scale (≥ T-score 55) were removed from the analysis. It would appear that elevated levels of defensiveness may impede the predictive validity of the PICTS GCT score, at least when it comes to assessing program completion in day reporting clients.
