The First Step in Validating the Criminogenic Cognitions Scale on a Sample of Romanian Prison Inmates: Variables Involved in Shaping a Profile of Criminogenic Cognitions

(1) Background: Criminogenic cognitions can influence criminal behavior and recidivism. The validation of the Criminogenic Cognitions Scale (CCS) within the cultural and social context of Romanian offenders, along with an understanding of their profiles, is essential for the development of effective rehabilitation. (2) Methods: The CCS was administered to 460 inmates across eight Romanian prisons, with the respondents having a mean age of 39.23 (SD 10.36; range 21–71). Data were analyzed using Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and the Kruskal–Wallis test. (3) Results: The Non-Acceptance of Responsibility (FAR) subscale had the highest internal consistency (Cronbach’s Alpha = 0.707), followed by Notions of Entitlement (NOE) (Cronbach’s Alpha = 0.683). The Negative Attitudes Toward Authority (NATA) subscale was considered valid with caution (Cronbach’s Alpha = 0.529). The highest FAR scores were observed among inmates convicted of sexual offenses, those who were widowed, and those with lower education levels. Higher scores were recorded on all scales for inmates who identified as drug users and those who perceived their punishment as unjust (p < 0.05). (4) Conclusions: The CCS is valid in the Romanian context, and the variability of criminogenic cognitions based on education level, type of offense, and perception of punishment should be considered when implementing rehabilitative measures.
