Changes in Criminal Thinking and Identity in Novice and Experienced Inmates

Criminal thinking and identity were assessed in 55 federal prison inmates with no prior prison experience (novice inmates) and 93 inmates with at least one prior adult incarceration and 5 or more years in prison (experienced inmates). Changes on the Self-Assertion/Deception scale of the Psychological Inventory of Criminal Thinking Syles (PICTS) and Centrality subscale of the Social Identity as a Criminal(SIC) questionnaire were congruent with the prisonization hypothesis and a priori predictions that measures of criminal thinking and identity would rise in novice inmates between initial assessment and follow-up but would remain stable in experienced inmates. On the other hand, experienced inmates recorded significant gains on the In-Group Affect subscale of the SIC. Incarceration, it would seem, may promote prisonization in both novice and experienced inmates.
