The Psychological Inventory of Criminal Thinking Styles and Level of Service Inventory-Revised: Screening Version as Predictors of Official and Self-reported Disciplinary Infractions

A total of 159 male inmates screened with the Psychological Inventory of Criminal Thinking Styles (PICTS) and Level of Service Inventory-Revised: Screening Version (LSI-R:SV) were followed for a period of 24 months for evidence of disciplinary infractions (incident reports). Eighty-three of these inmates also furnished a self-report of disciplinary infractions occurring during the 24-month follow-up. The PICTS General Criminal Thinking (GCT) score and LSI-R:SV total score correlated with and accurately identified the presence of an officially recorded disciplinary infraction, an officially recorded severe disciplinary infraction, and a self-reported disciplinary infraction but only age and the GCT score achieved incremental validity when age, GCT, and LSI-R:SV were included as predictors in the same probit regression or loglinear survival equation.
