Abstract
Despite the importance of criminogenic thinking in addressing criminal behavior, validated instruments to measure these cognitions in Portuguese forensic settings are scarce. Therefore, the main aim of this study was to explore the psychometric properties of the Criminogenic Cognitions Scale (CCS) in a sample of 364 Portuguese incarcerated males (M(age) = 37.88, SD = 10.88). An exploratory factor analysis was conducted, indicating a 15-item, two-factor structure (KMO = 0.82; Bartlett's test, χ(2) = 1841.2, df = 105, p < 0.001). The CCS dimensions, comprising Short-Term Orientation and Responsibility Evasion and Authority Resistance, demonstrated satisfactory psychometric properties, including convergent validity with antisocial traits, moral disengagement, and self-control dimensions, as well as internal consistency (omega coefficient = 0.60-0.77; composite reliability = 74-91; coefficient H = 89-95), and sensitivity of items. The CCS is a valuable tool within prison settings for assessing criminogenic thinking patterns, supporting risk assessment, the development of targeted rehabilitation programs, and monitoring cognitive changes over time to reduce recidivism, thereby promoting inmates' safer reintegration into society. Overall, our findings suggest the CCS is a promising tool for assessing criminogenic cognitions in the forensic Portuguese population.
